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 ...

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 ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

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 ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...
