Quantum Theory Scientists

Isaac Newton

developed classical mechanics, calculus, and came up with the corpuscular theory - that light is a stream of particles that can bounce off things. believes light has a particle-like nature.

Thomas Young

double-slit experiment - shines light through double slits and the light created a diffraction pattern on the wall. this made him believe that light was wave-like, not particle-like.

Albert Einstein

photoelectric experiment - shone a light on gold foil, releasing electrons that traveled through a wire to a bottle-shaped thing with gold leaves in it. the gold leaves would go out, and when the light was put nearer the leaves would go out even more. pro

Max Planck

black-body experiment - heated up a hollow metal sphere thinking the more NRG he gave it the higher wavelength the light would be, but this did not happen - it leveled off (ultraviolet catastrophe). this shows that classical mechanics doesnt work for this

Neils Bohr

established the H-model of the atom and quantum postulates. creates an equation relating to the required NRG required for electrons to change levels.

Louis de Broglie

maybe if light has particle/wave duality, then maybe matter and electrons do too." discovered that electrons have particle/wave duality and that they travel around the nucleus as a wave.
