The paths of photons are random, but coordinated

(Phys.org)—Researchers at the Niels Bohr Institute have demonstrated that photons (light particles) emitted from light sources embedded in a complex and disordered structure are able to mutually coordinate their paths through ...

Ultra-precise optical systems for space

(PhysOrg.com) -- Metal mirrors made with extremely high precision and exactly positioned are the key elements of modern telescopes. A new production technique enables complex optical surfaces to be manufactured with excellent ...
