Ahh .. an interesting email edition of 'How Stuff Works' today.
Although they have lots of sections, I've found they are especially
good at explaining info-technology. For example here is the 'table
of contents' for their first article, on computer ethernets (networks),
today. Although their articles can be rather basic I have found they
are excellent resource for students in many many areas of science.
