Fundamental interactions, also known as fundamental forces, are the interactions in physical systems that do not appear to be reducible to more basic interactions. Much like the periodic table of ...

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

In this video, we explore the Standard Model of particle physics, detailing the quantum field theories that describe fundamental particles and forces in the universe. Topics covered include: - ...

About 20 years ago, a physicist had an idea to reveal insights about a fundamental but enigmatic force at work in some of the most extreme environments in the universe. These environments include an ...

In recent years, a group of Hungarian researchers have made headlines with a bold claim. They say they’ve discovered a new particle — dubbed X17 — that requires the existence of a fifth force of ...

I'm teaching introductory Newtonian mechanics again this term, and as always I find myself fascinated by bits of the subject that my students are largely indifferent to. This week, that collided with ...

DEEP in a disused zinc mine in Japan, 50,000 tonnes of purified water held in a vast cylindrical stainless-steel tank are quietly killing theories long cherished by physicists. Since 1996, the ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...
