Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

But, of course, there’s a catch. The shorter the wavelength the higher the energy, so by the time you get down to these scales the photons used to image the samples are damaging or even destroying ...
