Lagoona Blue as a student of MITx MOOC 7.00 "The Secret of Life" Eric Lander PhD |
This morning,
Lagoona Blue was studying Hydrogen Bonds (not Hydrogen Bombs!!), a peaceful thing actually. She has learned that Oxygen is greedier than Hydrogen, on hence there'll be some negative charge on the side of Oxygen and some positive charge on the side of Hydrogen (water molecule H2O). The positive charge and the negative one behave like a magnet: they attract (+/- or -/+) or they repel (+/+ or -/-). "In a big cup of water, all of those molecules are doing that to each other. They're all weakly interacting by those little magnets. Hydrogen bonds mean: the water is all coupled to each other by these weak forces. It turns out that, nonetheless, because there are so many of them, water is highly, highly structured. There's a tremendous amount of structure in water. This is so strong bugs can walk on water. Bugs are walking on hydrogen bonds. The net that the bugs are walking on, that surface, is provided by the strength of all those hydrogen bonds. No hydrogen bonds, the bugs sink.
Next time you think about water, think about water as a highly, highly structured business..."
