During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
A UA-led collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential for new technological ...
Just as in the well-known children's story of Goldilocks and the Three Bears, something good happens when things are done in moderation, rather than in extremes.
Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).
Chinese scientists have pulled off a major feat with one of the sub-atomic world's weirdest phenomena: photons that behave like twins and experience the same things simultaneously, even over great distances.
A breakthrough into the full characterisation of quantum states has been published today as a prestigious Editors' Suggestion in the journal Physical Review Letters.
All light sources work by absorbing energy – for example, from an electric current – and emit energy as light. But the energy can also be lost as heat and it is therefore important that the light sources emit the light ...
