That plain ol' water was so complex?


"Solving water's 66 known anomalies
Water is familiar to everyone—it shapes our bodies and our planet. But despite this abundance, the molecular structure of water has remained a mystery, with the substance exhibiting many strange properties that are still poorly understood. Recent work at the Department of Energy's SLAC National Accelerator Laboratory and several universities in Sweden and Japan, however, is shedding new light on water's molecular idiosyncrasies, offering insight into its strange bulk properties.

In all, water exhibits 66 known anomalies, including a strangely varying density, large heat capacity and high surface tension. Contrary to other "normal" liquids, which become denser as they get colder, water reaches its maximum density at about 4 degrees Celsius. Above and below this temperature, water is less dense; this is why, for example, lakes freeze from the surface down. Water also has an unusually large capacity to store heat, which stabilizes the temperature of the oceans, and a high surface tension, which allows insects to walk on water, droplets to form and trees to transport water to great heights."

Interesting but you have way too much time on your hands.   :biggrin:
Arguing with Christians is like playing chess with a pigeon.  No matter how good I am at chess, the pigeon is just going to knock over the pieces, shit on the board and strut around like it's victorious.

The truth is slow, but relentless. Over time it becomes irresistible.

Dude ... I know it's weird, but I get off on that kind of stuff. I get that newsletter in my Inbox and sometimes it's a welcome diversion to read something other than IT journals.

And I like to share!  :biggrin:

Keep on sharing Bo!  I like reading that kind of stuff too!
