Wikipedia

I'm a big fan of Wikipedia. I think if you understand its limitations it is an excellent resource. I rarely use it for any in depth research but I use it all the time to answer quick questions and I use the main page as my homepage on my computer and try to learn something new every day and, if I have time, read the featured article. Today's featured article is on Alfred Russel Wallace, a biologist and contemporary of Darwin who, independently came up with a theory of natural selection that was essentially the same as Darwin's.

I may be biased but I thought this article was much more interesting than yesterdays biography of the race horse Go Man Go....

Plus, today's featured picture shows guttation - drops of xylem sap forced out of a plant by root pressure. A physical phenomenon we will mention briefly next quarter.
