Physics

A man in a colorful shirt holds a patterned ball while standing against a wall next to a periodic table and a book titled "For the Love of Physics." The scene cuts to a man in a suit standing on a stage in front of an audience, gesturing toward a physics demonstration setup with a track, lenses, and a laser beam, while smoke or vapor rises from the apparatus. He continues to explain the experiment, holding a cigarette in one hand and gesturing with the other, as the laser beam passes through the equipment.
