The Science of Discworld II - The Globe
It's not Terry Pratchett's latest, and while it's technically a Discworld novel, the alternating chapeters are by Ian Stewart and Jack Cohen - they write the science bit. I skipped the science bit. I wanted to be entertained. I didn't really want to ponder - I wanted Ponder. ;-) Here's what the inside flap says: "The planet Earth has picked up a parasite life form - elves. They get everywhere. And they like humans to be superstitious, fearful and frightened of thunder. They're after our future and must be stopped ... but by who? Enter the wizards of the Unseen University who, in the best-selling The Science of Discworld unwittingly created Earth and our own universe. At the time they quite failed to notice humanity. (Well, we've only been around for a million years, so we're easily overlooked ...) But now, at last they've found us." The Discworld novel within this novel is as usual, hilarious! The science and philosophy will make you ponder (sorry!). Excellent novel!
The first chef
First came fire ... and then, as the camera shifts to the soon to be late-village idiot, you're left wondering -- just what was going through that mind -- and food is put on the fire, for the first time, and cooking is accidentally discovered by humanity. The first chef is ridiculed by grunts, then the local thug tries a sample of the burnt carcass, and soon, everybody gets queued at the McDonalds drive-thru. What happened? Richard Wrangham of Harvard believes there's more to cooking than evolutionary history would have you believe. Wrangham points out that there is no way homo sapiens could survive on just raw food. Raw food just doesn't give up calories as easily as cooked food -- and raw food makes the digestive system expend more energy to get at those calories. Cooking on the other hand breaks complex molecules down, allowing the digestive system to make easy work of them -- and cooking also softens food, allowing the body to get to the calories with less effort...
