Forbes (March 10) -- Blog post from Chad Orzel: "...I was on the road last week giving a colloquium at the University of Illinois. As is typical for these trips, I visited a bunch of faculty research labs while I was there, including Brian DeMarco’s group, where they work in the same ultracold-atom field that is my own home in physics. They start with a gas of potassium atoms, cool them to a few billionths of a degree above absolute zero, and place them in an “optical lattice,” which uses light to create an array of places where the atoms would “like” to sit.
