Query: Hero worship can blind you to reality

Yes, Feynman was brilliant. Yes, Feynman revolutionized the teaching of physics. Yes, he seems to have been a delightful, charming, handsome, womanizing, fun guy to hang out with. But the Feynman cottage industry ran dry a long time ago. I expect his grocery lists to be published any day now to feed the insatiable hunger for anything that he touched. The essays and articles in this book are bland and nearly worthless. One is introduced as "uproarious." Uproarious is defined as "provoking hilarity." If you think anecdotes about Feynman running up a stairway to bring his heart rate up are hilarious, you are easily amused. This book was a complete waste of time and money.
