Writing the Magnetic Alphabet
Instead of pencil, paper, and eraser, we can use combinations of lasers and magnetic materials to write, read, and and erase information by varying the temperature and magnetic field. Here we apply our laser "pencil" to magnetic "paper" to write the letter “N” (Go Huskers!!). This technique allows us write, erase, and rewrite tiny magnetic memories like those found in your computer hard drive and other devices. Click to learn how it works!
Flubber and flow
Glaciers have shaped the face of our planet for millennia, developing over hundreds and thousands of years as layers of snow compress into solid ice. Or IS it . . . ? Click to learn how glaciers actually flow like a liquid, and how the surprisingly similar physics of Flubber can build our intuition for how real glaciers behave.
All the light we cannot see
Electromagnetic waves are the fundamental source of information about the universe, but only a tiny fraction of them are visible to the unaided eye. Fortunately, physicists have developed new ways to "see" outside the visible spectrum. Click to enter a universe BEYOND living color!
