Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

Greg Piefer is a UW-Madison College of Engineering product who is bullish about fusion uses today while urging patience over ...

An exotic new approach could shrink kilometer-scale machines into table-top devices.

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light ...

As NASA plans to establish a permanent Moon base via its Artemis program, it is looking to avoid the dangers of lunar ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This phenomenon is ...

Fusion technology is a long way from powering a grid — if it ever will. Dozens of fusion startups have launched anyway.

NASA will send astronauts Butch Wilmore and Suni Williams home from the International Space Station early on a previously ...

Matter is made up of small particles called atoms. Atoms can exist on their own or together as molecules. Atoms are very small and around 100,000,000 of them end to end would measure 1 centimetre ...
