Discover the physics that matters

Everyday physics

Conservation of linear momentum

From billiard balls and bullets to rockets and light, discover how a universal symmetry of nature preserves momentum everywhere.

Quantum physics

Quantum tunneling

A journey into the quantum world, where particles defy walls, probabilities rule, and tunneling powers the stars and life itself.

The theorising and discovery of black holes: the 2020 Physics Nobel

With increasing evidence being gathered about their existence, the 2020 physics Nobel finally recognised work done on black holes—but too late for Hawking.

Quantum physics

Bohr atomic model

By stating the problem with classical physics clearly, Niels Bohr showed us a new way of looking at the micro-world.

Why the BICEP2 results are important to physicists, part 2

How physicists use BICEP2, a telescope in the remote South Pole, to study polarisation of CMBR; and how some believe it should be verified first.
