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, ...
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) ...
Why quantum theory is just like magic (and Einstein deserves more credit in this field than he gets)
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 ...
An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result ...
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 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 ...
Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The recently rediscovered idea of quantum jamming complicates things. For the ...
