I'm not impressed by this silliness. I'm an atheist, and got 40 out of 40. there was only 1 word pair out of 40 that I had any doubt about. It was just a mater of picking the word with the least negative connotations. I've always respected Dr. Hawkins, but this doesn't strike me as his greatest work.

In a mathematical sense, non-linear refers to equations that are not well behaved. There are complex definitions of what that means if you got a few days to puzzle over them, after a few years of studying advance math that is. Much of what qualifies technically as non-linear involves higher order powers, logarithms, wave forms, derivatives, and integrals. That sort of thing.
