Transcription: Quantum mechanics is the study of motion in the micro-world of the atom. Quantum mechanical discoveries coming out of the study of light shook the foundations of science, including Newton's second law, F equals ma, which crumbled at the atomic level. Here's where it started. If you sifted particles like sand through trees, two holes in a plate, the sand particles would always pile up in two mounds on the table. But if a wave of water hit two holes in a brick wall, they would always create a diffraction pattern on the beach. Strangely enough, light can act like particles and waves, depending on ...
