The weird science of Light

More mind-blowing discoveries from quantum physics:

In the quantum optical laboratories at the Niels Bohr Institute, researchers have conducted experiments that show that light breaks with the classical physical principles. The studies show that light can have both an electrical and a magnetic field, but not at the same time. That is to say, light has quantum mechanical properties.

    Quantum physics is underaprieciated in theology and philosophy circles. People still speak as though we were in a Newtonian world.

    I find it fascinating that they keep finding infinitely smaller particles. The deeper we look the more we find.

  • I don’t have a subscription to JPL, so I can’t read the actual source article (not that I’m sure I’d understand it), but I can’t figure out what the news is here. Surely it’s not news that “light has quantum mechanical properties” — we’ve known that for, what, 50 years? What am I missing here?

    Please excuses my typos. I’m using my Father’s day gift, iPad. Anybody know how these things work? I grew up on windows.

  • Mike (@11), best I could tell, they had discovered a method by which the (long-known) quantum properties of light could be observed at a non-quantum level. Something like that. And the quantum property in question was the inability to know both position and momentum at the same time (as told us by the oft-misunderstood — including by me — Heisenberg uncertainty principle).

    Let me try again. Since I was in high school 20 years ago (and likely well before that), quantum physics has said that you can’t know both the position and momentum of something simultaneously. That’s Heisenberg. And quantum physics has been a very useful model in understanding and predicting how things work. But (here I’m speculating a bit), it would seem that never before had this particular theory from quantum had been observed at the “classical” level.
