Look into the pool of a research reactor and the water glows blue. That light comes from charged particles moving faster than light can travel in water, which relativity allows....

The Hanbury Brown–Twiss Effect: Why Photons Bunch
Light from a star arrives in clumps: photons are more likely to show up together than a random stream would allow. Here is how two radio astronomers found the effect,...

Huygens' Principle: How Every Point Becomes a S...
Every point on a wavefront acts as a new source. Here is what Huygens actually wrote in 1690, the two fixes Fresnel added, and how the principle predicts single-slit diffraction...

Why Does a Third Polarizer Let Light Through? T...
Cross two polarizing filters and the view goes black. Slide a third filter between them at 45° and light reappears, about one eighth of the original. Adding a filter lets...

How Did Rømer Measure the Speed of Light with Io?
In 1676, at the Paris Observatory, Ole Rømer noticed that eclipses of Jupiter’s moon Io came late when Earth was moving away from Jupiter and early when it was approaching....

A perfect lens still cannot focus light to a point. Waves spread out after passing through any opening, so every star becomes a tiny bright disk with faint rings, the...
