A technological revolution that is still playing out today began with new ideas about how atoms and subatomic particles work. Commentator Marcelo... One hundred years ago Niels Bohr introduced the ...

The roles of energy, momentum and orbital angular momentum conservation in high-harmonic generation were studied in the past. Here, we explore the role of spin angular momentum in high-harmonic ...

Physicists from the Canadian Institute for Measurement Standards are the first to measure a quantum mechanical wave function. And it only took 88 years from the formulation of Schroedinger’s equation!

One hundred years ago Niels Bohr introduced the idea of quantum jumps with his model of the atom. Since then, and in unexpected ways, quantum physics has taken over the world. Seeing the world through ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...
