Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

This video provides a simple explanation of symmetry and gauge theory, focusing on their foundational role in physics. It discusses symmetry as actions that leave an object's appearance unchanged, ...

Nobel prizewinner Alain Aspect’s ‘crackpot’ studies of quantum entanglement have explored the tricks reality plays on us — and built on ideas from a physics great. Einstein and the Quantum Revolutions ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means. Everyone has their favourite example of a ...

When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability ...
