The Manhattan Project
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
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
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
Ball lightning is a reported phenomenon in which a glowing, floating sphere of light appears, usually during thunderstorms. Many people claim to have…
The Nature of Time
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
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
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
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
Superconductivity is a remarkable state in which certain materials, when cooled below a critical temperature, conduct electricity with absolutely no…
The Higgs Boson
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
The neutrino is a tiny, almost massless subatomic particle that barely interacts with anything, streaming through matter, and through us, in…
Brownian Motion
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
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
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…
Grand Unified Theory
A Grand Unified Theory is a hypothesized framework that would merge three of the fundamental forces of nature, the electromagnetic, weak, and strong…
Crystallography
Crystallography is the science of crystals: how their atoms are arranged in orderly, repeating patterns, and how that hidden order gives crystals…
The Kinetic Theory of Gases
The kinetic theory of gases explains the behaviour of gases as the result of countless tiny particles, atoms and molecules, in constant, rapid,…
The Caloric Theory
The caloric theory was an explanation of heat, widely accepted into the early nineteenth century, which held that heat is an invisible, weightless…
The Coriolis Effect
The Coriolis effect is the apparent deflection of moving objects, such as air and water, when viewed from a rotating frame like the spinning Earth.…
