Smaller is Better

Here’s a challenge: envision a trillionth of something. You might think of one penny compared to 10 billion dollars.

Now you can add one more thing to the list, thanks to researchers in Zurich: a picometer, or a trillionth of a meter, is around the smallest distance that humans can resolve with a microscope. A team from IBM has refined their method to precisely measure the structural details of a single molecule. That is  3 picometers or 0.000000000003 meters. That’s one-hundredth the diameter of an atom.
