... The theory of quantum mechanics was developed by Erwin Schrödinger, Werner. According to quantum mechanics, the position and momentum of a particle cannot both be accurately known at the same time. Only its most probable position or momentum can be determined. The most probable distance between the ...

... Descartes famously defined: “matter is that which has mass and occupies space.” [Descartes]. Descarte’s thoughts on matter’s physical “extension” as its true basis for existence played a role in Newton’s thinking to refute Descartes on mass. Descartes also defined matter by extension, position, and ...

Quantum Physics Notes
... material didn't radiate electromagnetic waves continuously, but only at discrete values. He proposed that energy was quantized; it is not a continuous quantity. This energy was related to the frequency by E=hf. His quantum hypothesis suggests that the energy can only be whole number multiples of hf, ...

Bohr Atom
... To overcome this difficulty, Niels Bohr proposed, in 1913, what is now called the Bohr model of the atom. He suggested that electrons could only have certain classical motions: 1. The electrons can only travel in special orbits: at a certain discrete set of distances from the nucleus with specific e ...
