You're thirsty. You get yourself a glass of water. But have you ever wondered how many molecules of dihydrogen monoxide are in that glass of water? (There are around 8.35 x 1024
molecules in an 8-ounce glass of water, in case you're curious.) And how cool would it be if you could actually see those tiny little molecules dancing around in that glass? While that's still a challenge, researchers at the Lawrence Berkeley National Laboratory have managed to produce the first ever "action movies"
showing individual water molecules moving across a palladium surface using a special scanning tunneling microscope. Here are a few more examples of some cool atomic-scale imaging breakthroughs.
