Correspondence principle RIP

In reading Louisa Gilder’s book The Age of Entanglement, I was reminded of Bohr’s correspondence principle1 (originally analogy principle and also referred to as “Bohr’s magic wand”). I hadn’t thought about it much lately. Other than a few times in Lederman’s book Quantum Physics for Poets, the term wasn’t referenced in the other physics books… Continue reading Correspondence principle RIP

Quantum transport

After reading Chad Orzel’s article “How Do You Create Quantum Entanglement?” I discovered this 2011 TEDx 18′ video in which physicist Leo Kouwenhoven talks about what his lab at Delft University of Technology is actually building on the basis of spooky quantum superposition and entanglement. “Spooky” physics – Leo Kouwenhoven ( TEDxDelft) – uploaded on Nov 28, 2011. What… Continue reading Quantum transport

How to create entangled photon pairs

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

Pondering the infinitely small and large

So, after viewing some documentaries on modern physics and reading some books by “rock stars” in the field (see below), I felt a need to revisit my past musings, review topics and terminology, and organize all the “wow!” and “huh?” moments in my exploration. Recent media experiences: Everything and Nothing, two linked TV documentaries on Cosmology (Everything about… Continue reading Pondering the infinitely small and large
