As I continue to ponder the mind boggling character of quantum physics (the 10^-n reality), I’m fascinated by articles about novel experiments which routinely explore infinitesimal time scales and distances. Nanoscale (10^-9) is amazing! But now there’s the attosecond. This Space.com article (April 30, 2018), “The ‘Attoclock’ Shows How Fast Electrons Move in a Millionth of a Billionth… Continue reading What’s an attosecond?
Have you ever counted the number of things that you own which use lasers?1 One of the best know devices emerging from our understanding of quantum physics is the laser. Remember the meaning of the acronym? Laser pointers are cool, eh. We rely on lasers for communications, entertainment, health & safety, defense, retail services, manufacturing,… Continue reading How to create entangled photon pairs
