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 ...

A He-Ne laser shines on an adjustable single slit to make a diffraction pattern. The slit can be adjusted in two dimensions. Mount the laser and slit on opposite ends of the rail, making sure 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 ...

The authors discuss the valuable information that can be obtained from indexing and its applications in routine screening and analysis of solid forms. Crystal-structure determination using X-ray ...

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 ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
