Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics. A conservation law in physics describes the ...

Modern physics is weird. In quantum mechanics we have the Schrodinger’s cat thought experiment, a cat in a quantum ...

Killing horizon: a thought experiment suggests that the presence of a black hole can decohere a quantum superposition. (Courtesy: Shutterstock/Rost9) A new thought experiment suggests that the mere ...

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

Have you ever imagined the solution to a logic problem instead of calculating it? Such “thought experiments” are carried out using one’s imagination rather than doing actual research. Typically ...

A 155-year-old thought experiment, long thought to break the laws of thermodynamics, could be made real on a large scale. Maxwell’s demon is a thought experiment first proposed by Scottish ...

The Nobel Prize in physics this year has been awarded “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”. Read more: ...

The Matter of Everything tells the history of physics through experiments. Any book about the history of science for a general audience will, of necessity, be something of a distortion. The question ...
