Left: The first lines of the letter sent by Werner Heisenberg to Wolfgang Pauli on 9 July 1925, explaining his efforts to interpret quantum physics ...

WE publish this week, as a special supplement, the substance of an address by Prof. N. Bohr on the development of the theory of atomic structure, and in particular of the latest form and ...

Quantum mechanics, or quantum physics, is the body of scientific laws that describe the wacky behavior of photons, electrons and the other subatomic particles that make up the universe.

The Bohr model is a neat but quite imperfect depiction of the inner workings of an atom before things got too muddled up by quantum principles.

Quantum electrodynamics, or QED, looms large in physics. It’s an integral part of the standard model of particle physics, the theory of fundamental particles and their interactions.

The takeaway from Helgoland 2025 was that the foundations of quantum mechanics, though strongly built on Helgoland 100 years ...

Why Gravity Resists Unification. The Standard Model is built on a framework called quantum field theory. This theory merges classical field theory, quantum mechanics, and special relativity.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
