Thanks to the hard work of the Association of American State Geologists, the second week of October has been officially declared "Earth Science Week" every year since 1998. So we decided to have Jeopardy!'s rarest gem, Ken Jennings, school us on the hardest rock of them all: diamonds. Are they really forever? Are they a girl's best friend? Let's shed the cold, hard light of 10-carat truth onto some of these semiprecious superstitions.
The Debunker: Does "Lucy in the Sky with Diamonds" Stand for LSD?
In the spring of 1965, John Lennon and George Harrison and their wives were having dinner with a friend, the cosmetic dentist John Riley. (When you're the biggest rock stars in the world, you can hang out with pretty much any dentist you want!) Riley wanted the Beatles to try the newest craze in swinging London, so he laced their coffee with a still-legal lab chemical called lysergic acid diethylamide, or LSD. John wasn't crazy about the surprise, but ended up loving his first trip, which he described as "a very concentrated version of the best feeling I'd ever had." Acid became a big influence on John's songwriting, leading to Beatles classics like "She Said, She Said" and "Tomorrow Never Knows."
