I heard about Mario Livio's book Brilliant Blunders: From Darwin to Einstein -- Colossal Mistakes by Great Scientists That Changed Our Understanding of Life and the Universe on some sort of NPR interview that he did, and, based simply on the title, thought it might make for an interesting read.
It probably is, but it is not for me. I only got to page 13, and I decided that, although a real scientist would probably consider this title "popular science," it is still a little hardcore for me. Livio's basic idea is that great scientific discoveries don't pop out of nowhere; they are, in fact, made when scientists make lots of little mistakes and even a few huge ones while they're trying to figure stuff out.
The chapters cover scientists including Charles Darwin*, Lord Kelvin, Linus Pauling, and Albert Einstein, among others, and it certainly seems like a well-written book that the right reader might really enjoy.** But for me, right now, it's just a little dry: "The blunders described in this book have all, in one way or another, acted as catalysts for impressive breakthroughs--hence, their description as 'brilliant blunders.' They served as the agents that lifted the fog through which science was progressing, in its usual succession of small steps occasionally punctuated by quantum leaps." (pp. 10-11.)
*It didn't help that the book opens with Darwin and evolution, and I find evolution just about the most dull subject there is. If I even just hear the word "evolution," I start immediately yawning and my eyes get heavy.
**And I'm just totally scattered these days. If I had more time and my old powers of concentration I might have enjoyed this one a lot more too.
