Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...

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 ...

The advent of X-ray free-electron lasers (FELs) promises to eliminate the resolution limitation imposed on imaging of biological materials by radiation damage 1. Owing to the extreme brevity and high ...

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 ...

Classical Physics (Physics established mostly by Newton), has one property that we may think that is universal, which is, certainty. For example, by using the mathematics of Newton, we can precisely ...
