I had to buy a book for my program on Amazon (out of print book, which means private seller) and then I started looking at other books. I bought a few more books:
"The Beginnings of Western Science: The European Scientific Tradition in Philosophical, Religious, and Institutional Context, Prehistory to A.D. 1450"
"Creations of Fire: Chemistry's Lively History from Alchemy to the Atomic Age"
"The Scientists: A History of Science Told Through the Lives of Its Greatest Inventors"
"The Joy of Chemistry: The Amazing Science of Familiar Things"
Now I just gotta wait for them to arrive!!!
(yeah... this is why I don't go book shopping often....)
