New Articles in the Encyclopedia
This encyclopedia is constantly updated and expanded. Here is a list of the latest new articles, including those articles which have recently been strongly expanded or otherwise improved. The frequent smaller improvements of articles are not mentioned here.
Hint: instead of regularly visiting this page, you may find it more convenient to use the RSS feed for new articles. For this purpose, you must "subscribe" the RSS feed in your browser (possible e.g. in Internet Explorer 7 and Firefox 2) or use a special newsreader software. In Internet Explorer, you find the orange RSS icon to the right of the tabs, while in Firefox it is placed next to the address field. In Firefox you can install a so-called live bookmark, which will appear in the bookmark toolbar. Similarly, Mac/Safari users can use the RSS icon.
Note that there is another RSS feed for new articles in the Encyclopedia of Laser Physics and Technology.
