Thanks, it reminds me of Feynmann’s complaint about mathematics textbooks when he was reviewer for the Berkley school department. One book, in particular, consisted of nothing but blank pages. When he called the publisher, she apologized and said that all the reviewers had been accidently sent blank trade show props, with the correct glossy covers. Yet some of the reviewers had already submitted favorable recommendations!
I hated high school math, and in freshman year in college we were taught by a Chinese TA who could barely speak English, and then not intelligibly. (I got 795 on the SAT math level II achievement test, but never did math homework, I was somewhat like Lockhart, but I plugged through the hateful experience, because I needed a j-o-b.)
He was serving on the State Curriculum Commision of California, and it wasn't a mistake. The book hadn't been completed and the blank book was a required stand-in. And he didn't call the publisher, he raised the issue in a review meeting, saying he couldn't comment on it because he hadn't seen it. That's when he found out others had reviewed it.
This is in JUDGING BOOKS BY THEIR COVERS in "Surely You're Jokling, Mr. Feynman!" ( N.B. the quotes are part of the title ... and it's FEYNMAN ! )
