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 ...

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 ...

Describe young’s experiment of interference of light. Obtain the conditions of maxima and minima of light? Two waves of equal frequencies have their amplitudes in the ratio of 3:5. They are ...

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

If you ever had to make a difficult choice between two alternatives and unfortunately chose the one that turned out to be less favorable in retrospect, you probably wished you could simply turn back ...

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you'll produce an interference pattern because the particles ...

Researchers at MIT have conducted what they are calling the most "idealized" double-slit experiment yet, finding further evidence that Einstein's take on the phenomenon is likely incorrect. The double ...
