Ordered WaterDecember 4, 2012 at 1:04 pm | Posted in Media, Nature, Science | Leave a comment
You’re probably familiar with surface tension in water. However, the effect is much deeper than was previously thought. In this talk by Dr. Gerald Pollack, UW professor of bioengineering, he shows that, when exposed to light (energy), a visible layer of water self-orders and becomes a liquid crystal. It gains a negative charge, becomes more stable and viscous, and it excludes solutes – things floating in the water.
This explains a number of natural phenomena he questions during the start of the talk; like photosynthesis, why water vapour gathers into clouds, and why life uses water so much. He suggests some applications, like a water purifier. He even touches on why water had become an unpopular science and the ball was dropped.
