Mahmoud Riahi Un des Plus grands mathématiciens en Maroc !

Les plus grands mathématiciens de tous les temps Mahmoud Riahi a l'école Al Madina Polo
J'ai cherché une liste des plus grands mathématiciens de tous les temps sur Internet et je n'ai rien trouvé en français. J'ai donc décidé d'en reproduire une avec les liens Wikipédia.

Toute liste est sujette à polémique. Le classement que je propose en est un parmi d'autres. Je l'ai d'ailleurs repris sur ce site ( en anglais) et je ne pense pas que ma contribution apporte énormément à l'affaire. Si j'ai d'ailleurs nommé ce blog " Inclassables Mathématiques ", c'est devant le constat que la science du classement me parait elle-même inclassable ainsi que ses contributeurs.

La discussion au sujet  de l'ordre choisi peut d'ailleurs être intéressante, ainsi que les grands absents de cette liste. Le  H  apparaissant à coté d'un mathématicien indique qu'il apparait dans le livre de Stephen Hawking "Et Dieu créa les nombres" regroupant selon lui, les plus grands textes de mathématiques. Tag  indique un lien vers le tag correspondant dans ce blog. Vous pouvez aussi faire une recherche directe dans ce blog sur le nom du mathématicien en le sélectionnant.

Why Media Viewer?
The purpose of this tool is to:
 * Provide a richer multimedia experience, to match user expectations
 * Display images in larger size, on the same page as the thumbnail you click on
 * Reduce confusion when users click on thumbnails (bypass duplicate file info page on Wikipedias)

It aims to serve all users of Wikipedia, Commons and other MediaWiki sites (including new users, as well as very active editors). Note that this media viewer will initially only be for still images, as we are now using the Kaltura video player for audio and video. But over time, we would like to use the same UI across players, and eventually use a single viewer for all file formats.

Current features include:
 * Show images in larger, media viewer panel when you click on them
 * Modal panel opens up as overlay (on same page where you clicked)
 * Large image appears without clutter (Lightbox view)
 * Information about the image can be accessed easily (in Lightbox view)
 * Image can be shown in full-screen mode (full screen view)

How does Media Viewer work?




Media Viewer provides two different views of an image when you click on its thumbnail on an article page: Lightbox and Full Screen View.

Lightbox View
The 'Lightbox view' for this tool includes:

The image is shown in large size, as an overlay over the page where you clicked on the thumbnail, against a white, slightly translucent background. This makes the image stand out more and removes some of the visual clutter typically found on a text-heavy page.
 * Image

For the first release, we are offering these simple tools:
 * Tools
 * Close button (goes back to article view)
 * Full screen button (expands into full-screen view)
 * Lightbox button (returns to smaller image in browser Lightbox)

Here is the information that is shown above the image (see mockup):
 * Primary Info
 * File name (Zonotrichia atricapilla)
 * Author (e.g. Alejandro Erickson)
 * Source (e.g. Bird Institute)
 * License Info (e.g. CC-BY-SA-2.0) (or link to license info)

Here is the information that is shown below the image:
 * Secondary Info
 * Site name and link (e.g. Wikimedia Commons)
 * Description
 * Uploader name (e.g. Smallbones)
 * Creation Date (e.g. 12 April, 2012)

Full Screen View
The 'full-screen view' for this tool will show a large image across the entire screen, with minimal information and buttons available on hover, as shown in this mockup.

This is the view that lets you focus exclusively on the image, with no other distractions. When you click on the full screen icon, you see the largest version of the image that fits within the user's screen. The image is displayed across the entire screen (not just the browser window), set against a pure white background color that only shows the image. In this mode, you only see the file name and the author/source/license near the image, as well as link to Commons.

Bypassing the media viewer
If you would like to directly access the file description page of a given image without loading the media viewer at all, you can open the image in a new tab or window (typically accessible via right-click, or a combined keyboard+mouse action such as ctrl+click, depending on your browser and OS).

When will it be released?
A first beta version of Media Viewer will be released gradually in November 2013, as part of Beta Features, a new experimental program that will enable users to opt-in to test new beta features before they are released widely.

Media Viewer can now be tested by logged-in users on MediaWiki.org, on Meta.Wikimedia.org and on Wikimedia Commons. Based on test results, we have released it on all wikis worldwide on 21 November, 2013.

In the first release, the Media Viewer will only support the most widely used image file formats (e.g.: JPEG, GIF, PNG, TIFF, SVG), when users click on thumbnails in articles, galleries and category pages. In future releases, we plan to add support for PDF files, as well as audio and video files.

How can I help?


Can you help us test Media Viewer in coming days? The first version of this beta feature is now available for testing by logged-in users on all wikis, but we already have a lot of feedback and known bugs about it. So we invite you to test the newer version v0.2 on MediaWiki.org, on this demo page (don't forget to enable Media Viewer in your Beta Features preferences page). For a sneak peek at this new version 0.2 of the Media Viewer, check out the next section below.

To test either version of Media Viewer, click on the small 'Beta' link next to 'Preferences' in your personal menu. Then check the box next to 'Media Viewer' in the new BetaFeatures section of your user preferences — and click 'Save' (see screenshot). You can turn off any this options anytime, by reversing these steps. To test a variety of images in different file formats, you might like to check this Lightbox demo page.

Try out Media Viewer and let us know what you think on this discussion page. If you find any technical bugs, please [//bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki%20extensions&component=MultimediaViewer report them here on Bugzilla]. Based on your feedback, we will improve this feature in coming weeks.

You can test Media Viewer with different file formats on this special test page.

Next Version


The next version 0.2 of Media Viewer will focus on a 'full-width design' as the default view, to provide a more immersive user experience. You can test this new version v0.2 on MediaWiki.org, on this demo page. When you click on a thumbnail, you will see a larger image than you do now, with only a small sliver of meta-data at the bottom of the page, as shown in this mockup, also shown to the right.

The goal is to display images to fill the browser window as much as possible, aiming for up to 100% of the browser window width and up to 90% of its height. To speed up this display, we will try to fetch the thumbnail size that is closest to 100% of the screen width but no more t 90% of the screen height (instead of asking the server to pre-render custom sizes, which is too time-consuming). Note that may propose different display rules for portraits and images with special aspect ratios.
 * Image Display

The meta-data will now be shown below the image, and only include a few items above the fold (file name, license, author, source and uploader). But you will be invited to scroll down to see a lot more meta-data below, with a clear affordance letting know how to get more info. The mockups below show examples of how this would work.
 * Meta Data

Tools will be shown below the image (thank, flag, share, full-screen) (except for the 'X' close icon and next/previous arrows, which can be shown over the image on hover, as suggested by best practices from other media sites). Next, we will also mockup audio-video playback as well in this context (play/pause, rewind, fast-forward, volume, scrollable timeline).
 * First Tools

Desktop Mockups
Here are some preliminary mockups of designs we're exploring for desktop computers.

These mockups will be adjusted based on community feedback.

Mobile Mockups
Here are some preliminary mockups of designs we're exploring for mobile devices.

These mockups will be adjusted based on community feedback.

Again, this new version v0.2 can be tested on MediaWiki.org, on this demo page. Don't forget to enable Media Viewer in your Beta Features preferences page. Enjoy!
