Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Since most of the world-acknowledged masterpieces of painting are now safely behind museum walls, the few prizes that remain for big art hunters are all tagged, numbered and precisely located. A ...

De Foy has been working on inverse modeling to improve emissions inventories using long time series of hourly measurements at fixed sites. The inverse model was used to estimate emissions of elemental ...

Objectives Low back pain (LBP) is common in rowers and leads to considerable disability and even retirement. The athlete voice can help clinicians to better understand sport-related pain disorders. We ...
