Yes, he did, and that's the novel! He also invented the waterbed. And other things, I believe.

However, his characters use sliderules to calculate their trips between the Moon and Mars... there's a brilliantly funny scene in "The Rolling Stones" where the father, Grandma Hazel, the twins - Castor and Pollux- and the sister all calculate their course, and the sister's is off by orders of magnitude... she has them heading for Proxima Centauri, I believe. Sigh... I love that book. Just one great scene after another.

Oh, and he invented Tribbles, too - the guy who wrote that Star Trek episode admits he stole tribbles from the flat cats in "Rolling Stones".

That was a really good novel. I didn't know about the waterbed and Tribbles! Still have to read Rolling Stones.

BTW, I just finished Doomsday Book--"Apocalyptic!" :)
