L&FP, 65f: It’s all tangled up — quantum entanglement (vs how we tend to talk loosely)

Arvin Ash poses a macro scale parallel to entanglement (while using a Stern-Gerlach apparatus): Vid: Ash highlights, of course, that once entangled, particles have superposed wave functions leading to inherent non locality. So, spooky action at a distance overlooks that non locality. And as with the gloves, Alice needs to know her particle is part Read More…

At Big Think: The weirdness of quantum mechanics forces scientists to confront philosophy

Marcelo Gleiser: Due to space, I will only mention one more epistemic interpretation, Quantum Bayesianism, or as it is now called, QBism. As the original name implies, QBism takes the role of an agent as central. It assumes that probabilities in quantum mechanics reflect the current state of the agent’s knowledge or beliefs about the world, as he or she makes bets about what will happen in the future.

L&FP, 65e: Imaging light as a “wavicle” — both wave and particle

. . . using standing waves of light, vid: x Here is a snapshot: By setting up standing waves and using an electron beam to interact with it, a map could be imaged on photon location and waves. As an article explains: Until now [–> c 2015], scientists have only ever been able to capture Read More…

L&FP, 65: So, you think you understand the double slit experiment? (HT, Q & BA77)

So, here we go: And, the rise of solid state laser pointers makes this sort of exercise so much easier, BUT YOU MUST BE CAREFUL NOT TO GET SUCH A BRIGHT SOURCE INTO YOUR EYE AS THIS MAY CAUSE RETINAL BURNS THUS BLIND SPOTS. (I recall, buying and assembling a kit He-Ne laser to have Read More…
