A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of ...

Quantum mechanics, or quantum physics ... The Heisenberg-Schrödinger model of the atom, in which each electron acts as a wave around the nucleus of an atom, replaced the earlier Bohr model.

Five years later, scientists were able to peer inside a hydrogen atom ... The model has been superseded since Niels Bohr first proposed it in 1913, as our understanding of the quantum world ...

For example, the oxygen atom has eight electrons ... Eventually, the much more complicated quantum mechanical model emerged, superseding the Bohr model. But because things get far less neat ...

Did these researchers truly just crack our fundamental concepts of (quantum) physics wide open ... in the photonic energy getting absorbed by an atom, boosting the energy state of its electron ...

In the 1920s, when quantum mechanics was young ... Equations pepper the text, and important concepts, such as the Bohr model of the atom, are often discussed without explanation.

The Clash of Titans: Quantum Mechanics vs. General Relativity Quantum mechanics and general relativity, developed by Albert Einstein in the early 20th century, have both stood the test of time and ...

How could Arrhenius understand the basics of the greenhouse effect before quantum mechanics was even discovered ... a team of researchers used a simple model to prove that the logarithmic scaling ...

On small scales, we have the theory of quantum mechanics. A paradigm of quantum mechanics is the Standard Model, which explains many of the smallest particles and how they behave. On large scales ...
