During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

Electrons are extremely round, and some physicists are not pleased about it. A new experiment captured the most detailed view of electrons to date, using lasers to reveal evidence of particles ...

Although quantum mechanics is king of the hill when it comes to describing the properties of atoms, that doesn't mean classical physics is useless. In fact, the picture of an electron circling an ...

In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...

You may be familiar with matryoshka dolls: nested sets of painted figurines that fit within painted figurines. In the case of wooden dolls, the concept is pretty straightforward: hollow out a large ...

It’s like catching light in action. For the first time, physicists have measured changes in an atom to the level of zeptoseconds, or trillionths of a billionth of a second – the smallest division of ...

An international group of researchers, working on complex computer models for predicting the behavior of electrons, has discovered that those very computational models might not be as accurate as they ...
