Physicists are trying to rewrite the axioms of quantum theory from scratch in an effort to understand what it all means. The problem? They’ve been almost too successful. Scientists have been using ...

A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum physics. The findings ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

There are two theories we have that explain all the particles and their interactions in the known Universe: General Relativity and the Standard Model of particle physics. General Relativity describes ...

Real and imaginary: The time-dependent Schrödinger equation formulated using complex numbers. (Courtesy: iStock/piranka) Complex numbers are essential to achieve the most accurate quantum-mechanical ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

Quantum game theory represents an emerging interdisciplinary field that extends the classical paradigms of game theory into the quantum domain. By utilising principles of quantum mechanics—such as ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets ...

You might say it all started with a spot of hay fever. In June 1925, a young physicist named Werner Heisenberg retreated to the barren island of Helgoland in the North Sea, seeking respite from his ...
