La intensidad es una medida de los efectos de un terremoto: cómo se ha sentido, qué daños ha causado. Es una cosa distinta de la magnitud. No se mide con ningún aparato; hay que preguntar a la gente y estudiar sobre el terreno esos daños. La intensidad puede depender de la distancia al epicentro, pero no es una cosa matemática. Para clasificar los seismos de acuerdo con su intensidad tenemos la [[escala de Mercalli|http://es.wikipedia.org/wiki/Escala_sismol%C3%B3gica_de_Mercalli]].

Derived from NEUI (new-eee) but using a row, column, box model with the help of emastic framework. And there are some new goodies, like a sortable list makro for the ~MainMenu and ~TopMenu. ~ToggleLeft, ~ToggleRight. Fully functional, stand alone, icons. ~ThemeSwitcher at the options panel and more. Version: 0.6.3 ... have fun!

|''Version:''|1.0.1|
|''Date:''|Jan 04,2008|
|''Source:''|http://visualtw.ouvaton.org/VisualTW.html|
|''Author:''|Pascal Collin|
|''License:''|[[BSD open source license|License]]|
|''~CoreVersion:''|2.1.0|
|''Browser:''|Firefox 2.0; InternetExplorer 6.0|
!Demo
On the plugin [[homepage|http://visualtw.ouvaton.org/VisualTW.html]] :
*Try to tag some <<newTiddler>> with a tag displayed in the menu and edit MainMenu.
*Look at some tags like [[Plugins]] or [[menu]].
!Installation
#import the plugin,
#save and reload,
#optionally, edit TagsTreeStyleSheet.
! Usage
{{{<<tagsTree>>}}} macro accepts the following //optional// parameters.
|!#|!parameter|!description|!by default|
|1|{{{root}}}|Uses {{{root}}} tag as tree root|- In a //tiddler// content or template : uses the tiddler as root tag.<br>- In the //page// content or template (by ex MainMenu) : displays all untagged tags.|
|2|{{{excludeTag}}}|Excludes all such tagged tiddlers from the tree|Uses default excludeLists tag|
|3|{{{level}}}|Expands nodes until level {{{level}}}.<br>Value {{{0}}} hides expand/collapse buttons.|Nodes are collapsed on first level|
|4|{{{depth}}}|Hierachy depth|6 levels depth (H1 to H6 header styles)|
|5|{{{sortField}}}|Alternate sort field. By example : "index".|Sorts tags and tiddlers alphabetically (on their title)|
|6|{{{labelField}}}|Alertnate label field. By example : "label".|Displays tiddler's title|

!Useful addons
*[[FieldsEditorPlugin]] : //create//, //edit//, //view// and //delete// commands in toolbar <<toolbar fields>>.
*[[TaggerPlugin]] : Provides a drop down listing current tiddler tags, and allowing toggling of tags.
!Advanced Users
You can change the global defaults for TagsTreePlugin, like default {{{level}}} value or level styles, by editing or overriding the first config.macros.tagsTree attributes below.

| Estratos horizontales | Estratos no horizontales |

El principio de horizontalidad nos dice que cuando se formaron los estratos estaban en posición horizontal. Cuando nos encontremos estratos que no están horizontales tenemos que pensar qué causas han podido modificarlos. Por lo general serán deformaciones de origen tectónico.

En este tema hablaremos de un montón de cosas.
Los enlaces a los tiddlers del tema están ahí abajo.
Recuerda que @@color(brown):los tiddlers se abren, se leen, y se cierran@@. De lo contrario se empieza a llenar y nos hacemos un lío...

Los cloroplastos, como las  mitocondrias, tienen ADN y ribosomas en su interior lo cual hace pensar que sean descendientes de bacterias. Sin embargo, lo más importante que encontramos en estos orgánulos en un conjunto de membranas que reciben el nombre de ''tilacoides''. Estos tilacoides contienen grandes cantidades de ''clorofila'', una molécula que sirve como //antena// de captación de la energía solar para poder realizar la [[fotosíntesis]].
El espacio interno del cloroplasto se llama ''estroma'' y es un líquido similar al citoplasma.

La ''ecología'' es la parte de la Biología que estudia las relaciones entre los seres vivos entre sí y con el medio que los rodea.
La [[investigación que hemos hecho|informeecología]] sobre microorganismos de agua dulce es un pequeño estudio ecológico en el que hemos hecho hincapié en la metodología.
Para poder estudiar los ecosistemas debemos conocer las especies animales, vegetales,... que los habitan, con esta [[clave|https://sites.google.com/a/iesazucarera.es/claveplantasies/home]] podremos conocer algunas de las plantas que tenemos en nuestro instituto.

Dícese de los organismos que no son capaces de producir biomoléculas orgánicas a partir de moléculas inorgánicas (como el H~~2~~0 y el CO~~2~~). Por ese motivo, deben tomar las biomoléculas que necesitan de otros seres vivos (o muertos...).

Llamamos Geología Histórica a la parte de la Geología que investiga cómo era la Tierra en el pasado, comenzando desde el mismo momento de la formación del planeta. Esto abarca ni más ni menos que 4500 millones de años, de modo que la historia es larga. Sin embargo, todo tiene un [[origen]]...

Para reconstruir la historia geológica de una zona necesitamos //herramientas//. Las más importantes nos las aporta la [[Estratigrafía]], mediante una serie de [[principios básicos|Principios básicos de la Estratigrafía]] que debes conocer.

El sismograma es un gráfico que registra las ondas sísmicas que llegan a un lugar. El sismograma lo //dibuja// un aparato llamado ''sismógrafo''. En estos gráficos encontramos la información necesaria para saber a qué distancia y qué [[magnitud]] tiene el terremoto. Aquí tienes un ejemplo:

Unless you're delighted with the default theme you can make some quick changes by generating a new random color palette, hit this button to cycle through some alternatives.

<<RandomColorPaletteButton saturation_pale:0.67 saturation_light:0.53
saturation_mid:0.43 saturation_dark:0.06 pale:0.99 light:0.85 mid:0.5 dark:0.31>>

You can also change the look and feel completely by installing a new theme. To do this, find one you like in the @themes space, note down the name, and include it in this space by going to the space menu. You can reach the space menu by clicking on the blue and pink circle at the top-right of the page and chooshing "THIS SPACE". Here are a few to check out:
* @pip
* @caspian-ii
* @basalt
* @simplicity
* @cheesecake
* @jelly-doughnut

(//Note that if you are using a custom TiddlySpace install, these themes may not be present.//)

There are a lot of interesting people using ~TiddlySpace that you might like to keep track of and interact with. There are a number of ways of doing this.

If you see a number in the speech bubble in one of your tiddlers, it means that someone is writing about the same thing as you. You can find out what they're saying by clicking on it. Likewise, if you see something interesting in someone else's space, you can respond to it and write up your own thoughts on the subject by clicking "Reply to this tiddler".

Additionally, if you find anyone interesting, or you find an interesting looking space and you'd like to know when it's changed, you can "follow" that space. To do this, simply create a tiddler with the title: {{{@space-name}}} and tag it {{{follow}}}. If you want, you can store some notes about that space in the body of the tiddler.

If you then want to know what happening, simply [[include|How do I include/exclude spaces?]]@docs the @tivity space and then visit your activity stream at [[/activity|/activity]], or just visit the @tapas space directly.

!Not sure who to follow?
Here's a few suggestions:
* @fnd
* @cdent
* @pmario
* @bengillies
* @dickon

@@Please do not modify this tiddler; it was created automatically upon space creation.@@

Esta pregunta es fácil. Se puede resolver con una simple regla de tres. Si consideramos que la corteza tiene 40km de espesor queda así:

| Longitud(km) | % |
| 6370 | 100 |
| 40 | x |

lo que da ''un mísero 0.63%''. Es decir, que la corteza no es más que una peliculilla finísima que rodea la Tierra. Es insignificante comparada con el manto y el núcleo, pero es donde vivimos y de dónde sacamos todos los recursos geológicos (como el carbón, petróleo, minerales,...).
Aún así, tiene varios kilómetros de profundidad lo cual es mucho para el ser humano. No podemos atravesarla. El sondeo más profundo ha alcanzado los 16km, muy lejos todavía del manto. Es posible que nunca lleguemos a sacar muestras de rocas del manto. ¡Con lo interesante que sería...!

A series of plugins to link Scrapbooked pages to tiddlers.  They all share the dependency on the Firefox addin Scrapbook, which saves a Web page to a local archive in a predictable location.  The local TiddlyWiki must be sync'd to a server location along with the Scrapbook directory for it to work.

El primer proyecto del curso está dedicado al origen y evolución de nuestro planeta durante los primeros cientos de millones de años. Después de todo, la Geología se encarga del estudio de la Tierra, así que sería conveniente saber algo acerca de cómo se formó.
El primer eón de la historia terrestre es el [[Hádico|El Hádico]]. A éste le sigue el [[Arcaico|El Arcaico]].
Durante estas etapas tienen lugar acontecimientos fundamentales para comprender cómo es la Tierra hoy en día. Aparte de la formación del planeta, se formó la Luna, se diferenciaron las capas internas, se formó la hidrosfera y la atmósfera primitiva [[evolucionó|http://www.youtube.com/watch?v=u4tEVaobvrs]] hasta ser completamente diferente a la original.

----
Al acabar el proyecto deberás entregar un dossier que incluya:
*Línea del tiempo con todos los acontecimientos estudiados.
*Métodos de datación radiométrica.
**Fundamento teórico.
**Principales métodos.
**Simulación por ordenador.
**Modelo de laboratorio.
**Problemas realizados.
*Estudio monográfico de los meteoritos.
*Origen y evolución de la atmósfera.
*Origen y evolución de la hidrosfera.
*Concepto de cratón. Mapa con la localización de las formaciones geológicas más antiguas de la Tierra.
*Redacción acerca de la Tierra primitiva.

!!!Description
<<<
This macro is only needed if you want to use StylingPackage!
If you call {{{ <<xList>> }}} without any parameter you will get a non sortet list of all tiddlers.

!!!!UseCase
{{{
<<xList xCase [prefix] [regExp] [tag]>>
}}}
>*prefix .. can be any string. Default is "sort."
>*regExp .. can be any valid regExp, that runs against the tiddler title. Default is "." (any char except linebreaks)
>*tag .. "[tag[myTag]]" ''If you have spaces inside the tag, it has to be covered inside double quotes !!''
{{{
eg:
<<xList xCase "sort." "." "[tag[with spaces]]">>
}}}
>The above configuration will produce a custom field named {{{sort.with.spaces}}}. Because custom fields have to be lower case and spaces are not allowed. Since the tag name is used for the custom field, one tiddler can be part of different sorted lists.

La magnitud de un terremoto es una medida de la energía que se ha liberado en ese seismo. Podemos decir que un terremoto de elevada magnitud ha sido fuerte y que uno de poca magnitud ha sido débil. No estamos diciendo nada acerca de la destrucción o de los muertos que ha producido. Un terremoto de mucha magnitud puede no producir ningún daño (por ejemplo si tiene lugar en una zona totalmente despoblada). Es importante darse cuenta que __la magnitud del terremoto no depende de la distancia__ a la que estemos de él: es la misma en el epicentro y a 1000 km de él.
La magnitud de un seismo se suele dar en la escala de Richter. Hay que tener en cuenta que es una escala un poco especial porque en ella los decimales cuentan (y mucho como vemos [[aquí|http://www.youtube.com/watch?v=yNN7eDXzlMo]])

|Description|view any tiddler by entering it's title - displays list of possible matches|
''View a tiddler by typing its title and pressing //enter//.''  As you type, a list of possible matches is displayed.  You can scroll-and-click (or use arrows+enter) to select/view a tiddler, or press escape to close the listbox to resume typing.  When the listbox is not displayed, pressing //escape// clears the current input.
!!!Documentation
>see [[GotoPluginInfo]]
!!!Configuration
<<<
*Match titles only after {{twochar{<<option txtIncrementalSearchMin>>}}} or more characters are entered.<br>Use down-arrow to start matching with shorter input.  //Note: This option value is also set/used by [[SearchOptionsPlugin]]//.
*To set the maximum height of the listbox, you can create a tiddler tagged with <<tag systemConfig>>, containing:
//{{{
config.macros.gotoTiddler.listMaxSize=10;  // change this number
//}}}

{{{Exo}}} significa {{{por fuera}}} y {{{geno}}} significa {{{formación, origen}}}; así que las rocas exógenas son las que se {{{forman fuera}}}, es decir, las que se forman __por procesos que ocurren en la superficie terrestre__[[*|1]]. 
Los principales procesos externos relacionados con la formación de las rocas son:
*[[Meteorización]]
*[[Erosión]]
*[[Transporte]]
*[[Sedimentación]]
Muchas veces llamamos //rocas sedimentarias// a las rocas exógenas porque en la mayoría interviene el proceso de la sedimentación.
En la Naturaleza hay muchos tipos de rocas sedimentarias; por eso, los geólogos las clasifican en varios subtipos. Los más importantes son:
**[[Detríticas]]
**[[Carbonatadas]]
**[[Evaporíticas]]
**[[Orgánicas]]

En el interior de los lisosomas hay sustancias que son capaces de //descomponer// todo tipo de biomoléculas. Por eso decimos que se dedican a la //digestión celular//. Cuando una célula tiene que destruir algo (por ejemplo una bacteria que se ha comido...) lo hace con la ayuda de los lisosomas.

!Usage
The viewRevisions macro can be attached to any element, which should be passed
in as a parameter.

For example:

&lt;&lt;viewRevisions page:10 link:"<<view modified date>>"&gt;&gt;

would show the revisions "stack of cards" view, 10 at a time, when the modified
date is clicked.

El núcleo es un orgánulo ciertamente especial. Su función es almacenar la mayor parte del ADN presente en la célula (una pequeña parte está en las mitocondrias y cloroplastos -estos últimos en las células vegetales).
El ADN se presenta como moléculas muy largas y delgadas, imposibles de ver ni siquiera al microscopio. Forma lo que se llama ''cromatina''. Sólo cuando se va a producir la [[mitosis]] esos filamentos de ADN se superenrrollan para formar los [[cromosomas]].

Esta página es para poner cosas que os puedan ser útiles.
Lo primero que deberías hacer es quitar los menúes que tienes a la derecha y a la izquierda (si es que hay alguno) para tener más espacio en el centro. Para hacerlo, haz clic en cada una de las flechitas que hay en la barra de color arriba a la derecha. 
Lo segundo que puedes hacer es quitarte de en medio este mensaje clicando en la X que ves arriba a la derecha dentro de este rectángulo de texto (lo llamaremos //tiddler// a partir de ahora). Luego ya puedes empezar con el tema que quieras de los que hay en el menú de arriba a la izquierda...

Se debe hacer en forma de página web hecha con Google Sites. 
Esta página deberá contener:
**Página de Inicio con:
***Presentación del sitio, una introducción a qué hicimos en la excursión, cómo navegar por la página,...
***Google Mapa con enlaces a cada una de las paradas
Cada parada será una página en la que deberemos seguir el siguiente guión:
**Localización de la parada, diciendo dónde se sitúa y dando las coordenadas del lugar
**Geografía humana (cuando hayamos hablado de ello)
**Litología, es decir, descripción de los materiales y edad de los mismos
**Estructura tectónica e Historia Geológica (aquí deberá incluirse un corte geológico)
**Formas del relieve
**Ecosistemas (cuando hayamos hablado de ello)

!!!!!Usage
<<<
Specify which tags should be used for the columns and rows of the grid to ''see a particular cross-section'' of your document, or use //all// tags to ''get an instant 'birds-eye' overview of your entire document''.

Each grid cell contains a label with the number of tiddlers in that grid cell.  Click the number to ''show a popup of cross-indexed tiddler titles''.  Grid cells with no matching tiddlers contain a "-" (dash) that can be clicked to ''create new tiddlers automatically pre-tagged with that cell's combination of tags.''

To keep the grid display from getting very wide, the grid tags used as column headings are not initially displayed.  ''Click directly above the column to show/hide that heading'', or toggle all column headings at once by clicking the {{{>>>}}} symbol in the upper-left corner of the grid display.  Clicking a displayed row/column tag heading opens the tiddler whose title is that tag name.

The macro syntax to include a tag grid in your tiddler content is:
{{{
<<tagGrid "columntags" "exclude:tags" "rowtags" "exclude:tags" "filter:tiddlerfilter" startcolor endcolor open inline colorall sortrows sortcolumns>>
}}}
where:

''rowtags/columntags'' are each:
* a ''quoted'' space-separated lists of tags: {{{"tag1 tag2 [[tag3 with spaces]] tag4 ..."}}}
* //or,// a tiddler name preceded by "+": {{{+TiddlerName}}} where the specified tiddler contains a space-separated list of tags (same format as DefaultTiddlers)
* //or,// a tiddler name preceded by "@": {{{@TiddlerName}}} to use the same tags as those that are tagging the specified tiddler (i.e., the tiddler is a representative example of the kind of tags you are interested in cross-indexing)
* //or,// a tag name preceded by "=": {{{=tagName}}} to use the group of tags that are themselves, in turn, tagged with the indicated tagName (i.e., useful when you have defined a 'meta-tag'/classification system, a.k.a. "~TagglyTagging" techniques)
* //or,// keyword: {{{all}}} (use all tags)
* if only columntags are specified, rows display all tags by default
* if no parameters are provided, both rows and columns display all tags
''exclude:tag tag tag''
* This //optional// parameter can be placed immediately following the columntags and/or rowtags parameter to selectively omit certain tags from the grid row or column headings.  You can exclude several tags at once by enclosing the entire parameter in quotes, e.g.: {{{"exclude:tag tag tag"}}}.  This parameter is generally only needed to adjust the set of row/column headings that will be applied when using the {{{@TiddlerName}}} syntax.   Otherwise, you can simply omit the undesired rows/column headings directly from the specified columntags and/or rowstags parameters.
''"filter:tiddlerfilter"''
* By default, all tiddlers in the document are scanned to determine the contents of the grid cells.  The //optional// filter parameter allows you to specify a subset of tiddler to be scanned.  The syntax for this parameter is: {{{"filter:[tag[tagname]]"}}}, which will select only tiddlers with the indicated tag.  For more advanced selection of tiddlers, you can install [[MatchTagsPlugin]], which extends the {{{[tag[...]]}}} filter syntax to permit use of full boolean expressions, e.g., {{{"filter:[tag[NOT tag1]]"}}} or {{{"filter:[tag[tag1 AND NOT tag2]]"}}} or {{{"filter:[tag[(tag1 AND tag2) OR (tag3 AND NOT tag4)]]"}}}, etc.
''startcolor/endcolor''
* describes a ''color gradient'' where the grid cell background color is calculated as a combination of  the starting and ending colors, in proportion to the cell value
* colors are specified using 6-digit hex-coded RGB values (e.g., red="~FF0000", green="00FF00", blue="0000FF")
* the cells with the lowest number use the starting background color
* the cells with the highest number use the ending background color
* if one or both color values are omitted, all cells have //transparent// backgrounds
''open''
* causes the grid column headings to be shown when the grid is initially displayed (you can hide all the column headings using the &lArr; link, or just toggle one heading by clicking //near// the tag text.  (Note: clicking //on// the tag text will open the tiddler with the same name as the tag.
''inline''
* by default, cells with cross-indexed tiddlers display the total number of tiddlers in the cell.  When this number is clicked, a popup is displayed, containing links to the individual tiddlers in that cell.  However, the popup display makes it difficult to compare the contents of two or more cells because only one popup can be displayed at any given time.  To address this, you can use the ''inline'' keyword parameter to ''display the grid contents directly in the cells'', without using any popups.  While this can make the grid display significantly larger (to fit the text of each cell), it also enables quick comparisons between cells.  Inline rendering of the cell contents also makes it possible to print the entire grid contents for easy off-line reporting and analysis.
''colorall''
* by default, cells with no cross-indexed tiddlers have a //transparent// background (e.g., the tiddler's background colors shows through).  However, this can create a 'patchwork' appearance to the grid.  Add the ''colorall'' keyword parameter to force these 'empty' cells to use the specified startcolor instead of a transparent background.
''sortrows/sortcolumns''
* rowtags and columntags are normally displayed in the order specified in the macro parameters, or in alphabetical order when ''all'' is used to generate the list of tags.  Adding the ''sortrows'' and/or ''sortcolumns'' keyword parameters will sort the tags in decending order so that the most frequently used tags are displayed first (i.e., towards the top-left corner).

Las vacuolas son orgánulos típicos de las células vegetales. Su principal función es almacenar agua y sustancias disueltas. Suele haber una sola vacuola de gran tamaño.

El retículo endoplasmático puede ser de dos tipos:
*''rugoso'', que tiene ribosomas adosados a la cara externa de la membrana y se dedica a la síntesis (formación) de proteínas.
*''liso'', que no tiene ribosomas y se dedica a la síntesis de lípidos.

|''Name:''|XCaseListPlugin|
|''Description:''|Adds a new command ''xCase'' to the core list macro|
|''Author:''|Mario Pietsch|
|''Version:''|0.3|
|''Date:''|2010.08.03|
|''Status:''|''beta''|
|''Source:''|http://apm-plugins.tiddlyspot.com/#XCaseListPlugin|
|''License''|[[MIT License]]|
|''CoreVersion:''|2.5.0|
|''Requires:''||
|''Documentation:''|this file|
|''Keywords:''|list, sort, not case sensitive, filter|

!Description
This plugin performs a alphabetical sort for tiddlers. Default it is not case sensitive. That means ab = AB = aB = Ab! And it does some little more filtering using the RegExp syntax. The RegExp Syntax can be a little bit tricky to read and configure. But the best description I have found is at [[regular-expressions.info]]

!!!Example
{{{
<<list xCase title '[m]'>>
}}}
< <list xCase title '[m]'>>

!Default Format
{{{
<<list xCase>>
}}}

!More Possibilities
<<<
!!!Reverse sort order
{{{
<<list xCase -title >>
}}}

!!!Some basic filtering
*Every tiddler title, that starts with a number from 0 to 9.
{{{
<<list xCase title '[0-9]'>>
}}}

*Every tiddler title, that starts with an ''"a"'' or ''"b"'' or ''"c"''.
{{{
<<list xCase title '[abc]'>>
}}}

*Every tiddler title, that starts with exactly ''abc''.
{{{
<<list xCase title 'abc'>>
}}}
<<<

!!!Some advanced filtering
<<<
*same as above but with a tagList for additional filtering.
*adding the tag filter will disable the "excludeLists" setting !!
**If you need excludeLists, than you have to define it with the expression.
*XCaseListPlugin should be compatible to [[MatchTagsPlugin]] from TiddlyTools!

{{{
<<list xCase title '[a]' "[tag[MyTag]]">>
}}}

!!!Global / Local Settings
|<<option chkXCaseListCaseSensitive>> Global sort case sensitive |Sets case sensitiv sort globally|
|<<option chkXCaseListCheckField>> Sortfield defines case sensitive |Ignores global setting. Evaluates sortField and sets the value everytime <br> {{{<<list xCase sortField ..>>}}} is executed.|

If sortField is eg: 'title' .. not case sensitive (default).
if sortField is eg: 'Title' or 'TITLE' .. case sesitive sort is active.

Las rocas volcánicas no se consideran exógenas porque su origen está unos cuantos kilómetros en el interior de la corteza terrestre (aunque luego se formen en la superficie, cuando se produce una erupción...!)

La fotosíntesis es uno de los procesos biológicos más importantes de la Biosfera. La reacción química resumida es la siguiente:
CO~~2~~ + H~~2~~O &rarr; C~~6~~H~~12~~O~~6~~ (glucosa) + O~~2~~ (oxígeno)
La importancia viene del hecho de que es el (casi) único proceso que es capaz de transformar la materia inorgánica (CO~~2~~ y H~~2~~O) en materia orgánica (C~~6~~H~~12~~O~~6~~ (glucosa)). Como se utiliza agua como fuente de hidrógeno, se produce oxígeno (O~~2~~) como sustancia residual.
La materia orgánica producida en los cloroplastos podrá ser utilizada por la planta y servirá de alimento para todos los organismos heterótrofos de la Biosfera (entre ellos, nosotros...!)

2008.04.21 [1.7.0] added support for "filter:..." param to exclude tiddlers from grid
2008.01.08 [*.*.*] plugin size reduction: documentation moved to ...Info tiddler
2007.12.04 [*.*.*] update for TW2.3.0: replaced deprecated core functions, regexps, and macros
2007.07.24 [1.6.5] corrected handling for @TiddlerName with excluded tags, so that excluded tags are not actually removed from the @TiddlerName source tiddler.

!!!Description
<<<
To use this new toolbar command you have to add {{{addNow}}} to ToolbarCommands tiddler
eg:
{{{
|~ViewToolbar|tagSearch addNow +editTiddler  ...
}}}
<<<
!!!Date Format
<<<
Possible date formats can be seen at [[TiddlyWiki.org|http://tiddlywiki.org/#%5b%5bDate%20Formats%5d%5d]]

To change the date format add the following line to a tiddler eg: [[zzConfig]] tagged systemConfig
//{{{
config.commands.addNow.dateFormat = 'YYYY-0MM-0DD 0hh:0mm';
//}}}
To change the insert {{{mode}}} add:
//{{{
config.commands.addNow.mode = 'post';
//}}}
To change the {{{selectedText}}} in mode = 'pre' add:
//{{{
config.commands.addNow.selectedText = 'your text here';
//}}}

|''~CoreVersion:''|2.2.2|
!!!!!Usage:
<<<
Add the macro to the ViewTemplate, specifying the tag eg:"story" and a cookie: eg:"ACTIVESTORY" to navigate between the possible stories.
Find the line: 
{{{
<div class='viewer' macro='view text wikified'></div>
}}}
''and add the following line below:'' 
{{{
<div class='viewer' macro='storyGlue story ACTIVESTORY</div>
}}}
If you are allready using "navigation" macro. Replace "navigation" macro because it is called by StoryGlueMacro to handle navigation.
Don't delete it comment it !!
<<<
!!!!!Parameter
<<<
General Format: 
{{{
<div class='viewer' macro='storyGlue storyTag COOKIENAME</div>
}}}
storyTag: The macro searches all tiddlers tagged: "storyTag"
>If the tiddler is found in one or more stories. "selectStory" macro is activated instead of "navigation" macro to switch to a new story if you want.
>If it doesn't find a matching story nothing is displayed.

COOKIENAME is last part of an txtSelectStory option cookie, that storyGlue will look at. 
>The cookie is used, to store the name of the actual story, that will be used for navigating.
>The cookie can be manipulated also by SelectStoryMacro if the same name is used. 
>Bee carefull if you use a different name. Look at my examples!
>If you don't use SelectStoryMacro you will need a little program somewhere in your init functions.
>{{{config.options.txtSelectStoryCOOKIENAME  = "yourTiddlerThatContainsAStoryAndIsTaggedWithXXXX";}}}
>Better have a look at [[zzMptwUserConfigPlugin]] 

The option: {{{<<option txtSelectStoryACTIVESTORY>>}}}: ''<<varDisplay {{config.options.txtSelectStoryACTIVESTORY}}>>''
contains the active story, that is used in [[a-pm presentation manager|http://a-pm.tiddlyspot.com]].

If you click a tiddler, which is not part of the active story, but of any tiddler tagged: "story", storyGlue will activate the SelectStoryMarcro. SelectStoryMacro will display all stories found in a different color (default: blue). If you click on of the small sqares, it will activate this story, which can be used for navigatin now. 

The SelectStoryMacro can also work stand alone. See [[SelectStoryMacro]] for more details.
<<<
!!!!!Attention
<<<
There is no limit using different cookie names. ''But be warned: If you get confused. It is not my fault :)''
If your cookie name is eg: MYSTORY the option which contains the active story will be: {{{<<option txtSelectStoryMYSTORY>>}}}
It is always: txtSelectStory + yourCookieName.
In viewTemplate call it with: 
{{{
<div class='viewer' macro='storyGlue story MYSTORY</div>
}}}

|Description|adds support for resizing images|
This plugin adds optional syntax to scale an image to a specified width and height and/or interactively resize the image with the mouse.
!!!!!Usage
<<<
The extended image syntax is:
{{{
[img(w+,h+)[...][...]]
}}}
where ''(w,h)'' indicates the desired width and height (in CSS units, e.g., px, em, cm, in, or %). Use ''auto'' (or a blank value) for either dimension to scale that dimension proportionally (i.e., maintain the aspect ratio). You can also calculate a CSS value 'on-the-fly' by using a //javascript expression// enclosed between """{{""" and """}}""". Appending a plus sign (+) to a dimension enables interactive resizing in that dimension (by dragging the mouse inside the image). Use ~SHIFT-click to show the full-sized (un-scaled) image. Use ~CTRL-click to restore the starting size (either scaled or full-sized).
<<<
!!!!!Examples
<<<
{{{
[img(100px+,75px+)[http://upload.wikimedia.org/wikipedia/commons/thumb/0/0d/Andromeda_galaxy_2.jpg/800px-Andromeda_galaxy_2.jpg]]

!!Notes
* If TiddlerName doesn't exist it will be silently created
* Set label to '-' to specify no label
* See also http://mgtd-alpha.tiddlyspot.com/#ToggleTag2
!!Known issues
* Doesn't smoothly handle the case where you toggle a tag in a tiddler that is current open for editing
* Should convert to use named params

|Version|1.7.0|
|Author|Eric Shulman|
|Original Author|Clint Checketts|
|License|http://www.TiddlyTools.com/#LegalStatements|
|~CoreVersion|2.1|
|Type|plugin|
|Description|present a 'cloud' of tags (or links) using proportional font display|
!Usage
<<<
{{{
<<cloud type action:... limit:... tag tag tag ...>>
<<cloud type action:... limit:... +TiddlerName>>
<<cloud type action:... limit:... -TiddlerName>>
<<cloud type action:... limit:... =tagvalue>>
}}}
where:
* //type// is a keyword, one of:
** ''tags'' (default) - displays a cloud of tags, based on frequency of use
** ''links'' - displays a cloud of tiddlers, based on number of links //from// each tiddler
** ''references'' - displays a cloud of tiddlers, based on number of links //to// each tiddler
* ''action:popup'' (default) - clicking a cloud item shows a popup with links to related tiddlers<br>//or//<br> ''action:goto'' - clicking a cloud item immediately opens the tiddler corresponding to that item
* ''limit:N'' (optional) - restricts the cloud display to only show the N most popular tags/links
* ''tag tag tag...'' (or ''title title title'' if ''links''/''references'' is used)<br>shows all tags/links in the document //except// for those listed as macro parameters
* ''+TiddlerName''<br>show only tags/links read from a space-separated, bracketed list stored in a separate tiddler.
* ''-TiddlerName''<br>show all tags/links //except// those read from a space-separated, bracketed list stored in a separate tiddler.
* ''=tagvalue'' (//only if type=''tags''//)<br>shows only tags that are themselves tagged with the indicated tag value (i.e., ~TagglyTagging usage)
//note: for backward-compatibility, you can also use the macro {{{<<tagCloud ...>>}}} in place of {{{<<cloud ...>>}}}//
<<<
!Examples
<<<
//all tags excluding<<tag systemConfig>>, <<tag excludeMissing>> and <<tag script>>//
{{{<<cloud systemConfig excludeMissing script>>}}}
{{groupbox{<<cloud systemConfig excludeMissing script>>}}}
//top 10 tags excluding<<tag systemConfig>>, <<tag excludeMissing>> and <<tag script>>//
{{{<<cloud limit:10 systemConfig excludeMissing script>>}}}
{{groupbox{<<cloud limit:10 systemConfig excludeMissing script>>}}}
//tags listed in// [[FavoriteTags]]
{{{<<cloud +FavoriteTags>>}}}
{{groupbox{<<cloud +FavoriteTags>>}}}
//tags NOT listed in// [[FavoriteTags]]
{{{<<cloud -FavoriteTags>>}}}
{{groupbox{<<cloud -FavoriteTags>>}}}
//links to tiddlers tagged with 'package'//
{{{<<cloud action:goto =package>>}}}
{{groupbox{<<cloud action:goto =package>>}}}
//top 20 most referenced tiddlers//
{{{<<cloud references limit:20>>}}}
{{groupbox{<<cloud references limit:20>>}}}
//top 20 tiddlers that contain the most links//
{{{<<cloud links limit:20>>}}}
{{groupbox{<<cloud links limit:20>>}}}
<<<
!Revisions
<<<
2009.07.17 [1.7.0] added {{{-TiddlerName}}} parameter to exclude tags that are listed in the indicated tiddler
2009.02.26 [1.6.0] added {{{action:...}}} parameter to apply popup vs. goto action when clicking cloud items
2009.02.05 [1.5.0] added ability to show links or back-links (references) instead of tags and renamed macro to {{{<<cloud>>}}} to reflect more generalized usage.
2008.12.16 [1.4.2] corrected group calculation to prevent 'group=0' error
2008.12.16 [1.4.1] revised tag filtering so excluded tags don't affect calculations
2008.12.15 [1.4.0] added {{{limit:...}}} parameter to restrict the number of tags displayed to the top N most popular
2008.11.15 [1.3.0] added {{{+TiddlerName}}} parameter to include only tags that are listed in the indicated tiddler
2008.09.05 [1.2.0] added '=tagname' parameter to include only tags that are themselves tagged with the specified value (i.e., ~TagglyTagging usage)
2008.07.03 [1.1.0] added 'segments' property to macro object.  Extensive code cleanup

Las mitocondrias reciben con justicia el título de ''centrales energéticas'' de la ''célula eucariota''.
En ellas se producen grandes cantidades de la ''molécula energética'' de todos los seres vivos: el ''ATP''. Si en el citoplasma se pueden producir 2 moléculas de ATP por cada molécula de glucosa (nutriente), en la mitocondria esa misma molécula de glucosa producirá 38 moléculas de ATP.
Para ello, la mitocondria necesita oxígeno (por eso decimos que es un proceso //aerobio//).
La mitocondria es un orgánulo con muchas características especiales:
*su membrana es doble: una externa y otra interna.
*la membrana interna se extiende hacia el interior formando las ''crestas mitocondriales''.
*en su interior (que se llama ''matriz mitocondrial'') encontramos ribosomas y ADN, lo cual apoya la [[Teoría endosimbiótica]].

|Mitocondria vista al microscopio electrónico. Se aprecia que tiene una membrana doble y las crestas mitocondriales en su interior. Por fuera se ve gran cantidad de RER.|c

Binary tiddlers in TiddlyWeb when passed through the wikifier will be shown as images.
eg. {{{<<view text wikified>>}}} on a binary tiddler will show the image.
{{{<<view fieldname image>>}}}
will render the value of the tiddler field 'fieldname' as an image. This field can contain a tid
{{{<<image SiteIcon>>}}}
will create an image tag where the tiddler has content type beginning image and not ending +xml
will attempt to create svg object in other scenarios
{{{<<image /photos/x.jpg>>}}}
will create an image tag with src /photos/x.jpg as long as there is not a tiddler called /photos/x.jpg in 
which case it will render that tiddler as an image. Note for the case of svg files it will attempt to render as an svg if possible via the image
tag. It doesn't embed the svg in the dom for security reasons as svg code can contain javascript.

En sismología hay dos conceptos muy diferentes que debes saber distinguir: [[magnitud]] e [[intensidad]] de un terremoto. Está claro que en las facultades de periodismo que esto no se explica, porque pocas veces se oye usarlos adecuadamente en los telediarios. Ya sabes que el temblor de tierra se produce por las ondas superficiales R y L. Aquí tienes [[un vídeo|http://www.youtube.com/watch?v=jmpyrWFdE1I]] en el que las puedes reconocer.
----
Sobre la destrucción que provocan los terremotos hay mucho que discutir. Muchas veces oimos en los medios de comunicación que la Naturaleza es cruel con los países más pobres y no sé si eso es cierto. Con esta actividad intentaremos sacar alguna conclusión al respecto:
#Visita [[esta paǵina|http://es.wikipedia.org/wiki/Anexo:Terremotos_del_siglo_XX]] y [[esta otra|http://en.wikipedia.org/wiki/List_of_21st-century_earthquakes]].
#Haz una tabla con 15 terremotos que hayan tenido lugar después de 1950. Deberás elegir seismos que hayan destacado por ser de gran magnitud y/o por causar grandes pérdidas humanas. La tabla tendrá tres columnas: país-año, magnitud y número de fallecidos.
#Haz una gráfica que tenga en el eje horizontal la magnitud y en el vertical el número de muertes. Debe ser una gráfica de puntos (en cada punto, que es un terremoto, indica el país al que corresponde).
#Extrae al menos tres conclusiones a partir de la gráfica.
#En [[este mapa|https://maps.google.com/maps?q=http:%2F%2Ftoolserver.org%2F~para%2Fcgi-bin%2Fkmlexport%3Fproject%3Des%26article%3DAnexo%253ATerremotos_del_siglo_XX&ll=17.308688,156.269531&spn=65.138573,107.753906&t=m&z=3]] tienes la localización de todos los terremotos que salen en la tabla de los terremotos del siglo XX. 
#Saca un par de conclusiones de ese mapa.
#[[Aquí tienes|http://es.wikipedia.org/wiki/Anexo:Pa%C3%ADses_por_gastos_militares]] el ranking de países por su gasto militar. En [[esta otra|http://es.wikipedia.org/wiki/Anexo:Pa%C3%ADses_por_igualdad_de_ingreso]] puedes ver ordenados los países según las diferencias que hay entre sus habitantes más ricos y los maś pobres. [[Aquí|http://es.wikipedia.org/wiki/%C3%8Dndice_de_Percepci%C3%B3n_de_Corrupci%C3%B3n]] tienes un ranking de la corrupción en el mundo. Finalmente [[aquí está|http://datos.bancomundial.org/indicador/SH.XPD.TOTL.ZS?order=wbapi_data_value_2011+wbapi_data_value+wbapi_data_value-last&sort=asc]] lo que gastan en salud.
#Busca en las diferentes tablas los países de los terremotos que has representado en la gráfica y comenta su posición en cada una. Extrae conclusiones para cada caso.

Es ''el manto''. Podemos calcular su volumen fácilmente. Ya sabemos cuál es el volumen del manto más el núcleo. Podemos calcular el volumen del núcleo (que es una esfera) si sabemos cuál es su radio. Para eso debemos fijarnos en el modelo sísmico. Veremos que el núcleo comienza a 2885km de profundidad así que su radio es 6370km - 2885km = 3485km. Con la fórmula del volumen de una esfera obtenemos que V~~N~~ = 1.77x10^^11^^km^^3^^.
Con este dato podemos calcular el volumen del manto ya que

''V~~M~~'' = V~~M+N~~ - V~~N~~ = 1.06x10^^12^^km^^3^^ - 1.77x10^^11^^km^^3^^ = ''8.83x10^^11^^km^^3^^''

Si comparamos este valor con el volumen del núcleo vemos que claramente más grande. Con un sencillo cálculo podrás comprobar que el manto supone casi el 82% del volumen de la Tierra, de modo que es la capa (con diferencia) más importante del planeta.
A modo de resumen, esta tabla con los datos que hemos obtenido:

| ''Capa'' | ''Volumen (km^^3^^)'' | ''%''|
|Corteza | 2.03x10^^10^^ | 2 |
| Manto | 8.83x10^^11^^ | 82 |
| Núcleo | 1.77x10^^11^^ | 16 |
|Capas de la Tierra|c

Deberéis hacer un informe con los siguientes apartados:
----
*Título
*Objetivos
*Material
*Método: (es un apartado importante y debe explicarse bien la técnica utilizada en cada parte de la investigación)
**Toma de muestras
**Uso del microscopio del alumno
**Uso del microscopio del laboratorio
*Resultados
**Fichas de todas las muestras de agua estudiadas con mapa de localización exacta del lugar donde se tomó.
**Una ficha por cada organismo que hayamos estudiado. Incluirá:
***Clasificación
***Imágenes (se valorará la calidad)
***Descripciones
***Mediciones
*Conclusiones
*[[Tabla de recomendaciones|Cómo hacer un buen informe]] (con su valoración)
----
El informe se realizará en formato de presentación de diapositivas. Se puede hacer con googledrive o como se quiera, pero, en cualquier caso, debe subirse al google drive y compartirlo con bg@iesazucarera.es
----
Podéis encontrar imágenes de microorganismos de agua dulce en estas páginas. Es fácil que así podáis poner nombre (al menos del grupo al que pertenecen...) a vuestras imágenes.

Los núcleos de los isótopos radioactivos se desintegran en otros núcleos que son más estables. La ventaja para nosotros es que la velocidad a la que ocurre el proceso se puede conocer y, gracias a ello, podemos calcular la edad de los materiales geológicos o arqueológicos.

Llamamos Geología Histórica a la parte de la Geología que investiga cómo era la Tierra en el pasado, comenzando desde el mismo momento de la formación del planeta. Esto abarca ni más ni menos que 4500 millones de años, de modo que la historia es larga. Sin embargo, todo tiene un [[origen]]...

Para reconstruir la historia geológica de una zona necesitamos //herramientas//. Las más importantes nos las aporta la [[Estratigrafía]], mediante una serie de [[principios básicos|Principios básicos de la Estratigrafía]] que debes conocer.

Para //construir// la más sencilla de las células, que llamaremos ''PROCARIOTA'', necesitamos:
*Membrana celular: separa el interior del exterior. Sin ella no hay célula.
*Citoplasma: el medio interno, en el que tienen lugar multitud de ''reacciones químicas'' que permiten mantener la célula con vida. En el citoplasma se produce el ATP (molécula energética) que necesita la célula para realizar todas sus funciones.
*Biomoléculas: las más importantes de las cuales son
**el ADN
**las proteínas
*Ribosomas: que se encargan de //fabricar// proteínas.
Las células más complejas, que llamamos ''EUCARIOTAS'', tienen (además) muchos ''orgánulos membranosos'' como
*[[retículo endoplasmático]]
*[[aparato de Golgi]]
*[[lisosomas]]
*[[vacuolas]]
*[[mitocondrias]]
*[[cloroplastos]]
*[[núcleo]]

Podemos definir ''célula'' como:
*__unidad estructural__ de los seres vivos: es decir, la unidad necesaria para //fabricar// seres vivos. Utilizamos el término //estructural// para referirnos a //construcción//. Sin células no hay seres vivos lo mismo que sin fichas de Lego&reg; no hay construcciones de Lego&reg;...! La cuestión es ¿[[cómo son las células]]?
*__unidad funcional__ de los seres vivos: es decir, que no son piezas como las de Lego&reg;, que no hacen nada, sino que son unidades que //funcionan//, que hacen cosas. Si las células realizan sus funciones correctamente, el ser vivo vive; si no, lo normal es que el ser vivo muera. Las células,
**se relacionan
**se nutren
**y se [[reproducen]]
***por lo tanto, ¡¡LAS CÉLULAS SON SERES VIVOS!!
La parte de la Biología que se encarga del estudio de las células se llama ''Citología''

Etimológicamente {{{endo}}} significa {{{dentro, por dentro}}} y {{{geno}}} significa {{{formación, origen}}}; así que las {{{rocas endógenas}}} son las que se {{{forman por dentro}}}, es decir, las que se forman __por procesos que ocurren en el interior de nuestro planeta__. La profundidad puede variar mucho, desde pocos kilómetros hasta varias decenas de kilómetros.
Es un error habitual decir que estas rocas se forman en el centro de la Tierra así que ten cuidado!![[*|2]].

Podemos diferenciar dos grandes grupos dentro de las rocas endógenas:
**[[Rocas ígneas]]
**[[Rocas metamórficas]]

El centro de la Tierra está a más de 6000 km de profundidad.
Los geólogos no saben casi nada de lo que ocurre por debajo de los 20 km porque los pozos que se han perforado nunca han llegado tan profundo. No tenemos muestras en nuestros laboratorios cogidas a esas profundidades, sólo tenemos datos obtenidos gracias a las ondas sísmicas. Por eso decimos que nuestro conocimiento del interior del planeta es sobre todo //indirecto//.

|Description|Documentation for InlineJavascriptPlugin|
''Call directly into TW core utility routines, define new functions, calculate values, add dynamically-generated TiddlyWiki-formatted output'' into tiddler content, or perform any other programmatic actions each time the tiddler is rendered.
!!!!!Usage
<<<
This plugin adds wiki syntax for surrounding tiddler content with {{{<script>}}} and {{{</script>}}} markers, so that it can be recognized as embedded javascript code.  When a tiddler is rendered, the plugin automatically invokes any embedded scripts, which can be used to construct and return dynamically-generated output that is inserted into the tiddler content.
{{{
<script type="..." src="..." label="..." title="..." key="..." show>
	/* javascript code goes here... */
</script>
}}}
All parameters are //optional//.    When the ''show'' keyword is used, the plugin will also include the script source code in the output that it displays in the tiddler.  This is helpful when creating examples for documentation purposes (such as used in this tiddler!)

__''Deferred execution from an 'onClick' link''__
<script label="click here" title="mouseover tooltip text" key="X" show>
	/* javascript code goes here... */
	alert('you clicked on the link!');
</script>
By including a {{{label="..."}}} parameter in the initial {{{<script>}}} marker, the plugin will create a link to an 'onclick' script that will only be executed when that specific link is clicked, rather than running the script each time the tiddler is rendered.  You may also include a {{{title="..."}}} parameter to specify the 'tooltip' text that will appear whenever the mouse is moved over the onClick link text, and a {{{key="X"}}} parameter to specify an //access key// (which must be a //single// letter or numeric digit only).

__''Loading scripts from external source files''__
<script src="URL" show>
	/* optional javascript code goes here... */
</script>You can also load javascript directly from an external source URL, by including a src="..." parameter in the initial {{{<script>}}} marker (e.g., {{{<script src="demo.js"></script>}}}).  This is particularly useful when incorporating third-party javascript libraries for use in custom extensions and plugins.  The 'foreign' javascript code remains isolated in a separate file that can be easily replaced whenever an updated library file becomes available.

In addition to loading the javascript from the external file, you can also use this feature to invoke javascript code contained within the {{{<script>...</script>}}} markers.  This code is invoked //after// the external script file has been processed, and can make immediate use of the functions and/or global variables defined by the external script file.
>Note: To ensure that your javascript functions are always available when needed, you should load the libraries from a tiddler that is rendered as soon as your TiddlyWiki document is opened, such as MainMenu.  For example: put your {{{<script src="..."></script>}}} syntax into a separate 'library' tiddler (e.g., LoadScripts), and then add {{{<<tiddler LoadScripts>>}}} to MainMenu so that the library is loaded before any other tiddlers that rely upon the functions it defines. 
>
>Normally, loading external javascript in this way does not produce any direct output, and should not have any impact on the appearance of your MainMenu.  However, if your LoadScripts tiddler contains notes or other visible content, you can suppress this output by using 'inline CSS' in the MainMenu, like this: {{{@@display:none;<<tiddler LoadScripts>>@@}}}
<<<
!!!!!Creating dynamic tiddler content and accessing the ~TiddlyWiki DOM
<<<
An important difference between TiddlyWiki inline scripting and conventional embedded javascript techniques for web pages is the method used to produce output that is dynamically inserted into the document: in a typical web document, you use the {{{document.write()}}} (or {{{document.writeln()}}}) function to output text sequences (often containing HTML tags) that are then rendered when the entire document is first loaded into the browser window.

However, in a ~TiddlyWiki document, tiddlers (and other DOM elements) are created, deleted, and rendered "on-the-fly", so writing directly to the global 'document' object does not produce the results you want (i.e., replacing the embedded script within the tiddler content), and instead will //completely replace the entire ~TiddlyWiki document in your browser window (which is clearly not a good thing!)//.  In order to allow scripts to use {{{document.write()}}}, the plugin automatically converts and buffers all HTML output so it can be safely inserted into your tiddler content, immediately following the script.

''Note that {{{document.write()}}} can only be used to output "pure HTML" syntax.  To produce //wiki-formatted// output, your script should instead return a text value containing the desired wiki-syntax content'', which will then be automatically rendered immediately following the script.  If returning a text value is not sufficient for your needs, the plugin also provides an automatically-defined variable, 'place', that gives the script code ''direct access to the //containing DOM element//'' into which the tiddler output is being rendered.  You can use this variable to ''perform direct DOM manipulations'' that can, for example:
* generate wiki-formatted output using {{{wikify("...content...",place)}}}
* vary the script's actions based upon the DOM element in which it is embedded
* access 'tiddler-relative' DOM information using {{{story.findContainingTiddler(place)}}}
Note:
''When using an 'onclick' script, the 'place' element actually refers to the onclick //link text// itself, instead of the containing DOM element.''  This permits you to directly reference or modify the link text to reflect any 'stateful' conditions that might set by the script.  To refer to the containing DOM element from within an 'onclick' script, you can use "place.parentNode" instead.
<<<
!!!!!Instant "bookmarklets"
<<<
You can also use an 'onclick' link to define a "bookmarklet": a small piece of javascript that can be ''invoked directly from the browser without having to be defined within the current document.''  This allows you to create 'stand-alone' commands that can be applied to virtually ANY TiddlyWiki document... even remotely-hosted documents that have been written by others!!  To create a bookmarklet, simply define an 'onclick' script and then grab the resulting link text and drag-and-drop it onto your browser's toolbar (or right-click and use the 'bookmark this link' command to add it to the browser's menu).

Notes:
*When writing scripts intended for use as bookmarklets, due to the ~URI-encoding required by the browser, ''you cannot not use ANY double-quotes (") within the bookmarklet script code.''
*All comments embedded in the bookmarklet script must ''use the fully-delimited {{{/* ... */}}} comment syntax,'' rather than the shorter {{{//}}} comment syntax.
*Most importantly, because bookmarklets are invoked directly from the browser interface and are not embedded within the TiddlyWiki document, there is NO containing 'place' DOM element surrounding the script.  As a result, ''you cannot use a bookmarklet to generate dynamic output in your document,''  and using {{{document.write()}}} or returning wiki-syntax text or making reference to the 'place' DOM element will halt the script and report a "Reference Error" when that bookmarklet is invoked.  
Please see [[InstantBookmarklets]] for many examples of 'onclick' scripts that can also be used as bookmarklets.
<<<
!!!!!Special reserved function name
<<<
The plugin 'wraps' all inline javascript code inside a function, {{{_out()}}}, so that any return value you provide can be correctly handled by the plugin and inserted into the tiddler.  To avoid unpredictable results (and possibly fatal execution errors), this function should never be redefined or called from ''within'' your script code.
<<<
!!!!!$(...) 'shorthand' function
<<<
As described by Dustin Diaz [[here|http://www.dustindiaz.com/top-ten-javascript/]], the plugin defines a 'shorthand' function that allows you to write:
{{{
$(id)
}}}
in place of the normal standard javascript syntax:
{{{
document.getElementById(id)
}}}
This function is provided merely as a convenience for javascript coders that may be familiar with this abbreviation, in order to allow them to save a few bytes when writing their own inline script code.
<<<
!!!!!Examples
<<<
simple dynamic output:
><script show>
	document.write("The current date/time is: "+(new Date())+"<br>");
	return "link to current user: [["+config.options.txtUserName+"]]\n";
</script>
dynamic output using 'place' to get size information for current tiddler:
><script show>
	if (!window.story) window.story=window;
	var title=story.findContainingTiddler(place).getAttribute("tiddler");
	var size=store.getTiddlerText(title).length;
	return title+" is using "+size+" bytes";
</script>
dynamic output from an 'onclick' script, using {{{document.write()}}} and/or {{{return "..."}}}
><script label="click here" show>
	document.write("<br>The current date/time is: "+(new Date())+"<br>");
	return "link to current user: [["+config.options.txtUserName+"]]\n";
</script>
creating an 'onclick' button/link that accesses the link text AND the containing tiddler:
><script label="click here" title="clicking this link will show an 'alert' box" key="H" show>
	if (!window.story) window.story=window;
	var txt=place.firstChild.data;
	var tid=story.findContainingTiddler(place).getAttribute('tiddler');
	alert('Hello World!\nlinktext='+txt+'\ntiddler='+tid);
</script>
dynamically setting onclick link text based on stateful information:
>{{block{
{{{
<script label="click here">
	/* toggle "txtSomething" value */
	var on=(config.txtSomething=="ON");
	place.innerHTML=on?"enable":"disable";
	config.txtSomething=on?"OFF":"ON";
	return "\nThe current value is: "+config.txtSomething;
</script><script>
	/* initialize onclick link text based on current "txtSomething" value */
	var on=(config.txtSomething=="ON");
	place.lastChild.previousSibling.innerHTML=on?"disable":"enable";
</script>
}}}
<script label="click here">
	/* toggle "txtSomething" value */
	var on=(config.txtSomething=="ON");
	place.innerHTML=on?"enable":"disable";
	config.txtSomething=on?"OFF":"ON";
	return "\nThe current value is: "+config.txtSomething;
</script><script>
	/* initialize onclick link text based on current "txtSomething" value */
	var on=(config.txtSomething=="ON");
	place.lastChild.innerHTML=on?"enable":"disable";
</script>
}}}
loading a script from a source url:
>http://www.TiddlyTools.com/demo.js contains:
>>{{{function inlineJavascriptDemo() { alert('Hello from demo.js!!') } }}}
>>{{{displayMessage('InlineJavascriptPlugin: demo.js has been loaded');}}}
>note: When using this example on your local system, you will need to download the external script file from the above URL and install it into the same directory as your document.
>
><script src="demo.js" show>
	return "inlineJavascriptDemo() function has been defined"
</script>
><script label="click to invoke inlineJavascriptDemo()" key="D" show>
	inlineJavascriptDemo();
</script>

!!!!!Revisions
<<<
2010.12.15 1.9.6 allow (but ignore) type="..." syntax
2009.04.11 1.9.5 pass current tiddler object into wrapper code so it can be referenced from within 'onclick' scripts
2009.02.26 1.9.4 in $(), handle leading '#' on ID for compatibility with JQuery syntax
2008.06.11 1.9.3 added $(...) function as 'shorthand' for document.getElementById()
2008.03.03 1.9.2 corrected fallback declaration of wikifyPlainText() (fixes Safari "parse error")
2008.02.23 1.9.1 in onclick function, use string instead of array for 'bufferedHTML' (fixes IE errors)
2008.02.21 1.9.0 output from 'onclick' scripts (return value or document.write() calls) are now buffered and rendered into into a span following the script.  Also, added default 'return false' handling if no return value provided (prevents HREF from being triggered -- return TRUE to allow HREF to be processed).  Thanks to Xavier Verges for suggestion and preliminary code.
2008.02.14 1.8.1 added backward-compatibility for use of wikifyPlainText() in TW2.1.3 and earlier
2008.01.08 [*.*.*] plugin size reduction: documentation moved to ...Info tiddler
2007.12.28 1.8.0 added support for key="X" syntax to specify custom access key definitions
2007.12.15 1.7.0 autogenerate URI encoded HREF on links for onclick scripts.  Drag links to browser toolbar to create bookmarklets.  IMPORTANT NOTE: place is NOT defined when scripts are used as bookmarklets.  In addition, double-quotes will cause syntax errors.  Thanks to PaulReiber for debugging and brainstorming.
2007.11.26 1.6.2 when converting "document.write()" function calls in inline code, allow whitespace between "write" and "(" so that "document.write ( foobar )" is properly converted.
2007.11.16 1.6.1 when rendering "onclick scripts", pass label text through wikifyPlainText() to parse any embedded wiki-syntax to enable use of HTML entities or even TW macros to generate dynamic label text.
2007.02.19 1.6.0 added support for title="..." to specify mouseover tooltip when using an onclick (label="...") script
2006.10.16 1.5.2 add newline before closing '}' in 'function out_' wrapper.  Fixes error caused when last line of script is a comment.
2006.06.01 1.5.1 when calling wikify() on script return value, pass hightlightRegExp and tiddler params so macros that rely on these values can render properly
2006.04.19 1.5.0 added 'show' parameter to force display of javascript source code in tiddler output
2006.01.05 1.4.0 added support 'onclick' scripts.  When label="..." param is present, a button/link is created using the indicated label text, and the script is only executed when the button/link is clicked.  'place' value is set to match the clicked button/link element.
2005.12.13 1.3.1 when catching eval error in IE, e.description contains the error text, instead of e.toString().  Fixed error reporting so IE shows the correct response text.  Based on a suggestion by UdoBorkowski
2005.11.09 1.3.0 for 'inline' scripts (i.e., not scripts loaded with src="..."), automatically replace calls to 'document.write()' with 'place.innerHTML+=' so script output is directed into tiddler content.  Based on a suggestion by BradleyMeck
2005.11.08 1.2.0 handle loading of javascript from an external URL via src="..." syntax
2005.11.08 1.1.0 pass 'place' param into scripts to provide direct DOM access 
2005.11.08 1.0.0 initial release

Vamos a leer el Quijote y buscar en él pasajes en los que haga referencia a la Naturaleza.
Dividiremos el trabajo de modo que cada alumnoa leerá un solo capítulo y escribirá lo que encuentre acerca de animales, plantas, geología, clima,... todo lo que tenga que ver con la Naturaleza.
Aquí está el [[enlace a una versión online|http://www.elmundo.es/quijote/capitulo.html?cual=1]] de la obra maestra de Cervantes.

The popnote and poptiddler macros will be used extensively.  The syntax for the popnote macro is:
// //{{{<<popnote 'Text to display' 'Tiddler name' [open]>>}}}
For example,
// //{{{<<popnote 'This is the text to display' 'MainMenu' [open]>>}}}
will produce this:
<<popnote 'This is the text to display' 'MainMenu' [open]>>
Leaving the "open" out of the syntax:
// //{{{<<popnote 'This is the text to display' 'MainMenu'>>}}}
will produce this:
<<popnote 'This is the text to display' 'MainMenu'>>

The syntax for the poptiddler macro is simpler:
// //{{{<<popt MainMenu>>}}}
For example,
// // {{{<<popt MainMenu>>}}}
will produce this:
<<popt MainMenu>>

!!¿Qué son las galaxias?
Las galaxias son agrupaciones de miles de millones de estrellas separadas por enormes distancias que se miden en años-luz.

Un cromosoma no es más que un filamento de ADN superenrrollado. Como es más grueso, es posible verlo al microscopio óptico.
En un cromosoma hay muchos [[genes]]. En la especie humana las células //normales// tienen 46 cromosomas, así que hay muchos miles de genes en total.
Durante la //vida normal// de una célula los filamentos de ADN son sencillos, pero antes de la mitosis es necesario que cada filamento se duplique para que las dos células //hijas// tengan exactamente la misma información genética. Por eso, los cromosomas que vemos en la mitosis tienen la siguiente forma:
|[img(350px+,)[http://www.profesorenlinea.cl/imagenciencias/Cromatidas_image002.jpg]]|
|Cromosoma con dos ''cromátidas''. Las dos cromátidas tienen exactamente (salvo mutaciones) los mismos genes en las mismas posiciones. El punto en el que se unen las cromátidas se llama ''centrómero''.|c

Es la parte de la geología que estudia las [[rocas]]: sobre todo cómo son y cómo se han formado.
Los geólogos clasifican las rocas según __dónde se han formado__ en dos grandes grupos:
*[[Rocas endógenas]]
*[[Rocas exógenas]]

Vamos a hacer un póster para mostrar al mundo cómo es nuestro pueblo desde el punto de vista de las Ciencias naturales.
Los apartados generales y los correspondientes a la Geología ya puedes ir preparándolos.
El guión aproximado puede ser el siguiente:
*Título y subtítulos de los apartados.
*Localización geográfica.
*Estudio del relieve. Para ello podéis usar googlemaps usando la vista de relieve. Se debe incluir por lo menos un perfil topográfico. También se deben añadir fotos que dejen claro cuál es el relieve de la zona.
*Estudio de las rocas y sus edades geológicas.
**Para geología de todo el mundo: http://portal.onegeology.org/
**Para la [[Isla Bioko de Guinea Ecuatorial|http://www.geol.sc.edu/gegeo/guiadecampo/Bioko.htm]]
**Para geología de España: http://www.igme.es/internet/cartografia/cartografia/magna50.asp#Munici . Deberás ir buscando tu pueblo y acceder al mapa geológico de la zona.
***Puedes probar también con esta dirección http://www.igme.es/infoigme/visor/ es mucho más fácil, pero tendrás que instalarte un programa.

|Version|1.0||
!!!Description
A TiddlyWikiMacro to easily create a link to a [[Scrapbooked|http://amb.vis.ne.jp/mozilla/scrapbook/]] page.

/***

Example: 
Given this text in tiddler ScrapbookLocation -  <<tiddler ScrapbookLocation>>
Typing this in a tiddler: {{{<<sbk "Today in History" 20100523110142>>}}}
will generate this link: <<sbk "Today in History" 20100523110142>>

(to see this example work, you need to create ScrapbookLocation, and edit this tiddler, replacing the two timestamps with one of your own)



Directions:
!
# Create tiddler ScrapbookLocation
# Open an entry in a scrapbook in browser, and copy URL into ScrapbookLocation
# remove timestamp and index.url from URL, leaving the slash after "data"
# If you move your scrapbook, or put it on the Web, change ScrapbookLocation accordingly.

Todo lo relativo al origen de la Tierra son hipótesis que, además, es imposible comprobadar porque no podemos viajar hacia el pasado para ver cómo fue en realidad. Los científicos piensan creen que hay algunas cosas que están claras como por ejemplo:
**La Tierra se formó hace unos 4500 millones de años.
**Se formó por la aglomeración de millones y millones de cuerpos rocosos que llamamos ''planetesimales''.
**Los impactos de los planetesimales debieron generar cantidades inmensas de calor que mantuvieron fundido el //protoplaneta// total o parcialmente.
**El impacto de un protoplaneta contra la ''prototierra'' provocó la formación de la Luna.
**Durante ese estado de fusión los elementos más pesados (hierro y níquel) se //hundieron// hacia el centro y formaron el núcleo del planeta.
**El enfriamiento de las capas externas hizo que el material fundido se solidificase y se formase la //primera corteza terrestre//. Entre la corteza y el núcleo quedó el Manto.
**Esta corteza //atrapó// el calor interno de la Tierra, que va escapando poco a poco hacia el exterior desde entonces en un proceso que todavía no ha acabado.
**La //primera atmósfera// terrestre debió ser muy diferente a la actual. No tenía oxígeno porque los volcanes no producen oxígeno. Era rica en nitrógeno (N~~2~~) y dióxido de carbono (CO~~2~~).
**El agua presente en la Tierra procede de los cometas y meteoritos que bombardearon nuestro planeta hace unos 4000 millones de años.
**Por supuesto, en aquellos primeros millones de años no había vida en el planeta porque ni siquiera había agua líquida. La Hidrosfera se formó cuando la temperatura de la atmósfera bajó lo necesario para que el vapor de agua se condensase. Entonces empezaron a formarse los //océanos primitivos//, que serían de agua dulce ya que el agua de lluvia es dulce.
**Los océanos se hicieron salados a medida que los ríos llevaron sales disueltas. En cada ciclo hidrológico iría aumentando la cantidad de sales en el agua del mar. Las menos solubles, como el carbonato de calcio (~CaCO~~3~~), se fueron acumulando en el fondo formando rocas sedimentarias que llamamos //calizas//. Las más solubles, como la sal común (~NaCl), se fueron acumulando en el agua dándole el sabor salado que conocemos.

El Hádico es el primer eón de la historia de la Tierra.
Empieza hace más de 4500 millones de años con la formación de nuestro planeta y termina hace unos 4000 millones de años aunque esto no está del todo claro para los geólogos. 
Pero...¿cómo sabemos la edad la Tierra? La respuesta es corta: gracias a los [[métodos de datación por radioisótopos]].
Acerca del [[origen]] de la Tierra casi todo son hipótesis, lo cual no quiere decir que sean imaginaciones. Ya sabes que las hipótesis deben tener una base científica. Además, debe haber datos que las apoyen si quieren ser aceptadas por los científicos.

!Notes
* Borrows largely from ThemeSwitcherPlugin by Martin Budden http://www.martinswiki.com/#ThemeSwitcherPlugin
* Theme is cookie based. But set a default by setting config.options.txtTheme in MptwConfigPlugin (for example)
* Palette is not cookie based. It actually overwrites your ColorPalette tiddler when you select a palette, so beware. 

*MP Added the label to applyTheme macro.
*Made selectPalette tiddlySpace ready. 

!Usage
* {{{<<selectTheme>>}}} makes a dropdown selector
* {{{<<selectPalette>>}}} makes a dropdown selector
* {{{<<applyTheme>>}}} applies the current tiddler as a theme
* {{{<<applyPalette>>}}} applies the current tiddler as a palette
* {{{<<applyTheme TiddlerName>>}}} applies TiddlerName as a theme
* {{{<<applyPalette TiddlerName>>}}} applies TiddlerName as a palette

* {{{<<applyTheme TiddlerName label>>}}} applies TiddlerName as a theme and uses costumized button label
* {{{<<applyTheme {{tiddler.title}} label>>}}} applies actual tiddler as a theme and uses costumized button label

Click the "new tiddler" button towards the top right of the screen to write something in your space. You'll need to give it a title, some content and, optionally, some tags that will help you identify it later.

!Stuck for ideas?
Not sure what to write about? Not sure what to keep in your space? Other people use ~TiddlySpace for almost anything. How about some of the following:

* [[Save interesting sites|http://bookmarks.tiddlyspace.com]], images or articles from around the web so that you can refer back to them.
* [[Record your family tree|http://familytree.tiddlyspace.com]], store notes on long lost relatives or ancestors and map their relationship to you.
* [[Make up a pocketbook|http://pocketbook.tiddlyspace.com]] to store some useful information in, then print it out, [[fold it up|http://www.pocketmod.com/]], and take it with you.
* [[Plan your holiday|http://the-web-is-your-oyster.tiddlyspace.com/]], record where you're planning to go, note down places of interest and refer back to it later.
* [[Create a mindmap|http://mindmaps.tiddlyspace.com/]] to visualise your inner thoughts and see how they relate to each other.
* [[Set up a questionnaire|http://questionnaire.tiddlyspace.com/]] and get all your friends to answer it.

If you don't like any of those ideas, you can still use this space directly to keep notes and link them together, make a todo list and keep track of everything you're doing, or any one of a hundred million other things.

Still stuck? Check out the @featured space for more suggestions.

You can also [[socialise with others|How to socialise]].

|''Description''|Allows you to set the privacy of new tiddlers and external tiddlers within an EditTemplate, and allows you to set a default privacy setting|

|''Source''|http://github.com/TiddlySpace/tiddlyspace/raw/master/src/plugins/ToggleTiddlerPrivacyPlugin.js|
!Notes
When used in conjunction with TiddlySpaceTiddlerIconsPlugin changing the privacy setting will also interact with any privacy icons.

Currently use of
{{{<<setPrivacy defaultValue:public>>}}} is in conflict with {{{<<newTiddler fields:"server.workspace:x_private">>}}}

There is an option, found in the tweak tab of the backstage, called txtPrivacyMode. Set this to either ''public'' or ''private'' depending on your security preference. If you choose not to set it then it will default to ''public''.
!Params
defaultValue:[private|public]
Allows you to set the default privacy value (Default is private)

|Based on|http://www.TiddlyTools.com/#CreateTiddlersFromCSV|
|Version|1.3.1|
|Author|Eric Shulman|
|Modder|@pmario|
|License|http://www.TiddlyTools.com/#LegalStatements|
|~CoreVersion|2.1|
|Type|html|
|Description|create tiddlers from CSV data|
|Modifications|added defaultCustomFields for TiddlySpace compability. added "saveChanges" button below the input area. |

!FORMAT
<<<
~Comma-Separated Value (CSV) format:
{{{
title,modifier,tags,text,customfield1,customfield2,...
MyTiddler,YourName,tag1 [[tag 2]] tag3,"This is ""quoted"" content, with a comma",value,value,...
}}}
{{wrap{
''The first line contains lower-case field names and must include a //"title"// field''.  Subsequent lines define //~CSV-encoded// data: any values that contain quotes or commas are surrounded by double-quotes, and quotes occuring //within// the values are doubled-up.  The ''tags'' field is entered as a //space-separated bracketed list//. Additional fieldnames ("fieldN") are added as custom tiddler fields. Important for ~TiddlySpace users: The {{{modified, created}}} date-fields are set by the server.
}}}
<<<
!end

REVISIONS:
[1.3.1] remove debugging message
[1.3.0] correct handling for embedded quotes and strip \r from input
[1.2.0] convert created/modified values from strings to date objects
[1.1.0] handle CSV-encoded embedded commas and quotes

/***
|Name|ScrapbookImagePlugin|
|Created by|[[Steve Schneider|http://webarchivist.org]], built on ImageLinkMacro|
|Version|1.0||
!!!Description
A TiddlyWikiMacro to easily create an image link to a [[Scrapbooked|http://amb.vis.ne.jp/mozilla/scrapbook/]] page.

/***

Example: 
Given this text in tiddler ScrapbookLocation -  <<tiddler ScrapbookLocation>>
and this text in tiddle ImageLocation - <<tiddler ImageLocation>>
Typing this in a tiddler: {{{<<sbki select-make.png 20100523112405 "Select Make Feature" http://www.autotrader.com/ 2010-05-23>>}}}
will generate this link: <<sbki select-make.png 20100523112405 "Select Make Feature" www.autotrader.com 2010-05-23>>


Directions:
!
# Create tiddler ScrapbookLocation
# Open an entry in a scrapbook in browser, and copy URL into ScrapbookLocation
# remove timestamp and index.url from URL, leaving the slash after "data"
# If you move your scrapbook, or put it on the Web, change ScrapbookLocation accordingly.
# Create tiddler ImageLocation and put location of images files there

|''Name''|TiddlySpaceTiddlerIconsPlugin|
|''Version''|0.8.10|
|''Status''|@@beta@@|
|''Author''|Jon Robson|
|''Description''|Provides ability to render SiteIcons and icons that correspond to the home location of given tiddlers|
|''Source''|http://github.com/TiddlySpace/tiddlyspace/raw/master/src/plugins/TiddlySpaceTiddlerIconsPlugin.js|
|''Requires''|TiddlySpaceConfig BinaryTiddlersPlugin ImageMacroPlugin TiddlySpacePublishingCommands|
!Notes
{{{<<tiddlerOrigin>>}}} shows the origin of the tiddler it is being run on.
In TiddlySpace terms this means it will determine whether the tiddler is external, public or private.
Where private it will analyse whether a public version exists and distinguish between the different scenarios.
If a tiddler is external, the SiteIcon of that external space will be shown

!Parameters
width / height : define a width or height of the outputted icon
label: if label parameter is set to yes, a label will accompany the icon.

groups by the server.bag field (this version contains TiddlySpace specific code for turning a bag into a space name)

{{{groupBy modified dateFormat:"YYYY"}}}
group tiddlers by year.

{{{<<groupBy tags exclude:excludeLists exclude:systemConfig>>}}}
group tiddlers by tag but exclude the tags with values excludeLists and systemConfig

Within that group you can also exclude things by filter
{{{groupBy modifier filter:[tag[film]]}}}
will group tiddlers tagged with film by modifier.

// //''Name:'' Popnote Plugin

// //''Description:'' 
// // Create a direct link to a tiddler using a normal button and a button that expands the specified tiddler inside the current tiddler.
// // To display the included tiddler initially visible just pass ''open'' in the third parameter (not actually the only possible value but you can interpret it like that).
// // The expand button can also collapse the included tiddler, this will actually remove the included contents. If the included tiddler is changed you can simply expand it again.

Una vez que ya hemos definido si la roca es ígnea, metamórfica o exógena, la clasificación //detallada// de la roca se suele hacer basándonos en su contenido mineral. Dos rocas se pueden diferenciar por los minerales que presenten o por las cantidades en los que aparecen cada uno de ellos.
Para clasificar las rocas se usan a menudo [[diagramas triangulares|http://ocw.upm.es/explotacion-de-minas/termodinamica-quimica-ii/contenido/ProblemasPropuestos/diagrama_triangular_10.gif/image]] que debemos aprender a utilizar e interpretar. Luego, con la ayuda de páginas [[como ésta|http://www.insugeo.org.ar/libros/misc_18/02.htm]] podremos dar nombre a las rocas.
