What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Researchers announced last week that they had slowed down faint pulses of laser light and retrieved an image from that light after speeding it back up. In principle such "slow-light" technology might ...

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

Electrons travelling through two slits and a single slit. (Courtesy: Herman Batelaan/New Journal of Physics) Physicists in the US and Canada say that they have done the best job yet of realizing ...
