Bob Enyart

It took years to work through the problems of getting it uncorrupted so it could be published.

And so the ninth edition came out because before that, you guys, Real Science Radio in the Bob Enyart days, we're all about the hydroplate theory and people could go to the website and read his eighth edition.

And now, you know, people want to hear, well, I want to hear more about the idea play theory.

Where's his book? Actually, the eighth edition doesn't have the radioactivity chapter, but and the ninth edition is corrupted.
