For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is ...

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

The pioneer of quantum computing talks about how Albert Einstein would have reacted to his experiments, the hype around the ...

Artificial intelligence has begun to tackle a task once thought to be uniquely human: designing scientific experiments. And not just any experiments. Researchers at University College London have used ...
