Clemson professor Leo Rebholz disliked every textbook available for an advanced mathematics course he taught for mechanical engineers.
Mostly, he hated the high costs publishers charged for the books.
“I eventually said we’re not going to use a book anymore because I don’t like any of them and I’m tired of you guys paying, I think it was, $120 for the book we used for a while,” Rebholz said.
So he wrote his own, culled from lecture notes and co-authored by Timo Heister, a mathematical science assistant professor.
The book was just published. He’s selling it for $19.90 and expects to make about 20 cents per copy.
