Researchers at MIT have made large gains, for a field of science that studies extremely small particles.

Some of those tiny particles — called neutrinos — traveled from Illinois to Minnesota (a distance of about 450 miles) and, along the way, proved the idea of superposition, a property of the quantum theory, which scientists have only been able to prove thus far for extremely small distances.

Guests

Joseph Formaggio, associate professor of physics and head of the Experimental Nuclear and Particle Physics division at MIT.

David Kaiser, history of science and physics professor at MIT.
