Physicists are one step closer to cooling down antimatter.
Reality Doesn’t Exist Until We Measure It, Quantum Experiment Confirms
Australian scientists have recreated a famous experiment and confirmed quantum physics's bizarre predictions about the nature of reality, by proving that reality doesn't actually exist until we measur...
Direct measurements of the wave nature of matter
New experimental techniques map out wave properties only known previously from theory.
Pilot Wave Theory and Quantum Realism
There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it's...
A living thing in two places at once? This quantum quandary test is limited
A recent proposed microbe experiment based on Schrödinger’s counter-intuitive theory would have a scale so small as to be almost meaningless, and other challenges such as consciousness also come into ...
Iodine Molecular Movie
This movie, derived from LCLS data, shows an iodine molecule moving in the first 2 trillionths of a second after being excited by a laser pulse. The clouds o...
Radioactive particles have been spotted across Europe
The presence of the radioactive compound Iodine-131 was first detected in Norway in January. Particles have now been detected in Poland, Germany, France and Spain.
NASA Mystery: Electron 'Superhighway' Traveling at Speed of Light Discovered Just Outside Earth's Magnetic Field
"This is a puzzling case because we're seeing energetic electrons where we don't think they should be, and no model fits them," said David Sibeck, co-author and THEMIS project scientist at NASA Goddar...
We May Have Found a Way to Cheat the Second Law of Thermodynamics
Physicists created a new quantum theorem for entropy, and included is a possible exception.
2016 Nobel Prize In Physics Awarded To David Thouless, Duncan Haldane And Michael Kosterlitz
They were honored for their work in revealing the secrets of exotic matter. Their discoveries, using advanced mathematics, had boosted research in condensed matter physics and raised hopes for uses in...
A New ‘Einstein’ Equation Suggests Wormholes Hold Key To Quantum Gravity
A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.
China Launches The First Quantum Communications Satellite – And What Is That, Exactly?

Schrödinger’s cat just got even weirder (and even more confusing)
The researchers hope their findings will help make quantum computers a reality.
Newborn babies intuitively understand quantum mechanics
Quantum mechanics is notoriously perplexing. But there's one set of humans who innately understand how it works.
Atomic theory
In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. It began as a philosophical concept in anci...

Quantum mechanics
Quantum mechanics (QM; also known as quantum physics, or quantum theory) is a fundamental branch of physics which deals with physical phenomena at nanoscopic scales, where the action is on the order o...
Quantum mechanics - Wikipedia
An atom is the smallest unit of matter that defines the chemical elements. Every solid, liquid, gas, and plasma is made up of neutral or ionized atoms. Atoms are very small: the size of atoms is measu...
