Physicist Elmer Imes’ careful work to capture the spectra of molecules made clear the worth of the theory of quantum mechanics. Shine a beam of white light through a chemical sample, then send that ...

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical? Most physicists expect that when we zoom in on the ...

Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical ...
