Before the Big Bang
Here's an article from Discover magazine that nicely explains superstring theory -- extending the concept to origin of the universe, contending that there wasn't necessarily a singularity where the universe began, but rather, our universe may have been the result of the collision of two other universes that exist in a space that has up to 10 spatial dimensions. This may be a cycle that repeats itself endlessly, birthing new universes regularly -- but because we can only perceive four dimensions, this theory will only remain a mathematical conjecture -- however, a conjecture that promises to unite macro predictions relativity with the subatomic predictions of quantum mechanics. It's a beautiful idea.
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...
