Quantum field theory is the framework that combines quantum mechanics with Einstein's special relativity to describe the fundamental particles of…
Conservation of momentum is one of the most fundamental and reliable laws in all of physics. Momentum, the product of an object's mass and its…
The Standard Model is the theory that describes all the known elementary particles of matter and the forces that act between them, except for…
Mass and energy are two forms of the same thing. This is the meaning of the most famous equation in science, which states that the energy contained…
Time travel, journeying into the past or the future, is a staple of science fiction, but is it actually possible? The surprising answer from physics…
The Manhattan Project was a secret American research effort during World War II that produced the first atomic bombs. A vast scientific and…
The Large Hadron Collider, or LHC, is the world's largest and most powerful particle accelerator, built by the European laboratory CERN near Geneva.…
Quantum computing is a new kind of computing that harnesses the strange rules of quantum mechanics to process information in ways ordinary computers…
Ball lightning is a reported phenomenon in which a glowing, floating sphere of light appears, usually during thunderstorms. Many people claim to have…
Time is one of the most familiar parts of our experience, yet what it really is remains one of the deepest and most contested questions in physics…
Isaac Newton (1642 to 1727) was an English mathematician and physicist, widely regarded as one of the greatest scientists who ever lived. His…
Radioactive decay is the process by which unstable atomic nuclei spontaneously break down, releasing energy and particles and transforming into other…
The bending of starlight is the deflection of light by gravity, predicted by Einstein's general theory of relativity and confirmed during a solar…
Superconductivity is a remarkable state in which certain materials, when cooled below a critical temperature, conduct electricity with absolutely no…
The Higgs boson is a fundamental particle whose discovery in 2012 confirmed how other particles acquire mass. Long predicted but famously hard to…
The neutrino is a tiny, almost massless subatomic particle that barely interacts with anything, streaming through matter, and through us, in…
Brownian motion is the random, jittery movement of tiny particles suspended in a fluid, caused by their constant bombardment by the fluid's…
The photoelectric effect is the release of electrons from a material when light shines on it. Simple to observe yet impossible to explain with older…
Gravitational waves are ripples in the fabric of space and time, set off by some of the most violent events in the universe. Predicted by Einstein a…
