I just visited a very interesting site called “did you ever wonder?“. Some of the topics included “How to rebuild the surface of a cell?”, “How soil keeps the world in balance?”, “About the invisible marvels of the nanoworld?”, and “How to carve with light?”. Each month the site features new questions and new personalities.
I discoved the site in the Scout Report, which I have been reading the every weekend for quite a few years. It is really excellenet. The Scout Report is a weekly publication offering a selection of new and newly discovered Internet resources of interest to researchers and educators. However, anyone is welcome to subscribe to one of the mailing lists (plain text or HTML).
The Scout Report provides a short summary about each new link. There are three categories: Research and Education, General Interest, and Network Tools. In the pre-Google days I would add a link or two that I thought was particularly interesting every week to the favorite Places section of my web site. It grew to more than 1,000 links and it is organized into a dozen categories with additional sub-categories. I still get emails from people saying they find it useful. I am sure there are some broken links there but I do my best to keep the old ones pruned out and add some new ones.
