Core
Here's one out of SciFi and comic books. This guy is serious though. David Stevenson of the CalTech proposes to blast a rift through the Earth's crust of several hundred metres in length and depth, and about 30 centimetres wide - probably using a nuclear device. He would then send probes down the fissure to study the Earth's core. I'm not sure about you, but isn't invasive experimentation a thing of the past? And should we really be cutting up lab-rat-Earth to see how it works? This is akin to a flea deciding a really good idea would be to make a great gash into a dog to study how it works. Sound or not, I'm not for this.
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...
