Another excellent book along this line which is a personal favorite of mine is Imagining the Universe.  I see that Amazon lists multiple used copies of ItheU for less than $3, a very cheap price indeed for purchasing the secrets of the Universe – get a copy for your kids and read it for yourself.

While you’re waiting for dead-tree book delivery, check out the EXTREMELY COOL Java slide show at the Florida State University Molecular Expressions site, where there is so much other great stuff to see I’m going to just shut up and let you get started on it.  Enjoy!

By the way – how do I find all these links? Simple: Google !!!!
