The positions of all the atoms in a sample of a metallic glass have been measured experimentally — fulfilling a decades-old dream for glass scientists, and raising the prospect of fresh insight into ...

A 40-atom gold nanocluster breaks from gold's signature dense packing, forming square atomic planes with a central channel that accelerates electron relaxation about 80x.

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Explore the fascinating world of atoms in this 3D animated video. Discover the structure of atoms, including protons, neutrons, and electrons, as well as their significance in the universe.

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

The big idea of atomic theory is that, at some smallest, fundamental level, the matter that makes up everything can be divided no further. Those ultimate building blocks would be literally ἄ-τομος, or ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of ...

Of the four fundamental forces, gravity is the most familiar—seemingly unchanging, ubiquitous, and maybe even a little boring. We first meet gravity while dropping our first toys, and later get to ...

Why is our Universe the way it is, and not some other way? There are only three things that make it so: the laws of nature themselves, the fundamental constants governing reality, and the initial ...
