- Atom Interferometry- Detecting The Undetectable
If one beam travels a fixed length and another travels an extra distance or in some other slightly different way, the two light beams overlap and interfere when they meet up, creating an interference pattern that scientists inspect to obtain highly precise ...

- A Quantum Kiss Between Nanoparticles That Changes The Color Of Space
Researchers have observed the quantum regime in the interaction between nano-sized spheres of gold, thanks to the change of color of the gap between these particles when they are at distances of less than one nanometer. They have literally 'seen' ...

- End-Run Around The Diffraction Limit: Shrinking Light To Billionths Of A Meter
In modern times, we have been spoiled by the ability of the private sector to make technology shrink in both cost and size- but Moore's Law can't do that forever using regular electrical signals. Maybe it is time for Moore's Light to take o ...
