Eileen Collins
Read about Eileen Collins -- NASA's first female shuttle commander. Before her, shuttle commanders had been only men, mostly due to the fact that shuttle commanders were chosen from the ranks of pilots who had logged hours flying test aircraft. That's still true, and Eileen Collins served in the ranks of the test pilots. Due to the recent drop in US manned missions to space however, there hasn't been many opportunities for other women to join Eileen Collins -- so to date, she remains the only female to have commanded a shuttle mission.
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...
