A wonderful book on 5 unheralded scientists that most have never heard about. Ira has a knack of explaining technical details in a way that the layman can identify with while telling a good story behind those people who he is writing about.
My favorite story in the book is about Henrietta Swan Leavitt. It's hard to fathom just how little women were respected & treated 100 years ago. Leavitt did allot to help change this, while adding significant methods & knowledge to astronomical research. Truly, she was a pioneer in more than one way.
All this, plus the fact that Ira is a fine writer as well. I've enjoyed reading his many different articles on the web for years now. It's great to have this compilation now in available in one place. I can't recommend this book strongly enough. Get it, you will enjoy reading it!
