A: Some people think that an atom is the smallest form of matter, but it’s not. Every atom is made up of subatomic particles – protons, electrons and sometimes neutrons. Protons themselves are now ...

Physicists have started running the world's largest particle accelerator at a new record energy and taking the first data from these ultra-powerful collisions. Protons zoom around the 17 mile (27 ...

IBM’s Scanning Tunneling Microscope, or STM for short, uses an atomically sharp needle that passes over the surface of an (electrically conductive) object – the distance between the tip and object ...

GENEVA - Scientists working at the world's biggest atom smasher near Geneva have announced they are confident that the new subatomic particle discovered last summer is a version of the long-sought ...

Confine electrons within microscopically thin layers of material and weird things happen. Experiments on semiconductors in the 1980s demonstrated that to physicists (SN: 10/17/98, p. 247). Now, two ...

The new experiment demonstrated a bizarre quantum effect from the double-slit experiment at an unprecedented scale. When you purchase through links on our site, we may earn an affiliate commission.

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 ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

Scientists shined a little light, literally, on the perplexing processes that govern atoms, in a new experiment that showed the effect of bouncing one photon of light off an atom. Atoms and particles ...
