Apr 23, 2024 · Werner Heisenberg contributed to atomic theory through formulating quantum mechanics in terms of matrices and in discovering the uncertainty principle, which states that a particle’s position and momentum cannot both be known exactly.
In Niels Bohr’s theory of the atom, electrons absorb and emit radiation of fixed wavelengths when jumping between fixed orbits around a nucleus. The theory provided a good description of the spectrum created by the hydrogen atom, but needed to be developed to suit more complicated atoms and molecules.
Werner Karl Heisenberg (pronounced [ˈvɛʁnɐ kaʁl ˈhaɪzn̩bɛʁk] ⓘ; 5 December 1901 – 1 February 1976) was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics, and a principal scientist in the Nazi nuclear weapons program during World War II.
Werner Heisenberg contributed to atomic theory through formulating quantum mechanics in terms of matrices and in discovering the uncertainty principle, which states that a particle’s position and momentum cannot both be known exactly.
Learn how electrons behave as matter waves and how the Heisenberg uncertainty principle limits our knowledge of their position and energy. Explore the concepts of de Broglie wavelength, Schrödinger equation, atomic orbitals, electron spin and Stern-Gerlach experiment.
- In the spin quantum number the electrons are represented either by +1/2 or -1/2, and as shown in the quantum numbers video it is said that the elec...
- It's mostly a function in mathematics. It would be like asking "what is the average distance of a cosine wave from the center?" - and this might se...
- The shapes have been calculated from Schrodinger's equation. Moreover , the shapes represent the region where the probability of finding the electr...
- Isn't to do with the fact that the velocity is not quite 0? if you know it is exactly 0 then the uncertainty in the position is infinite as well (m...

- You can't cancel out the ψ's like that because Hψ is not H times ψ but rather H operating on ψ (that's what the ^ over the H indicates). The Hamilt...
- I think I can safely say that nobody understands quantum mechanics. - Feynman So you are right on track! :) But to be more pedagogical, you can vie...
- I never thought about it before. Its interesting question. My guess is that it is transverse. though, to honest, there is so much dispute about the...
- Spin is just a property that electrons (and other particles) have. It got named spin back when people were working with the Bohr model and trying t...
- Atomic orbitals are defined by energy levels not positions. The electron clouds that are depicted are usually where there is a 90% chance of findin...
Oct 8, 2001 · In atomic physics the observational data were obtained from spectroscopy and associated with atomic transitions. Thus, Heisenberg was led to consider the “transition quantities” as the basic ingredients of the theory.
5 December 1901 – 1 February 1976. Theoretical physicist famed for the quantum uncertainty principle. By Richard Webb. It might seem an obvious statement that there are limits to what we know, but...
