Entanglement and the EPR Paradox | #Halloween2019

"Spooky action-at-a-distance". Albert Einstein used these words to express his disbelief about a certain interpretation of quantum mechanics. In this video, we will take a look at entanglement and the Einstein-Podolsky-Rosen paradox and see whether physics is really spooky or not.

Please make separate video on Bell's inequality.
Thanks

So why can't the two particles know their states before? You forgot to tell us -sthg about Bells?
Is it only Bells that shows this?

The entangled particles are described by a single wavefunction!

A recent video from another source informs that the preferred spin of an electron is down and that by applying energy at a particular frequency it can be made to spin up essentially opening a gate enabling accurate writing to a quantum chip. For an entangled pair of electrons, possibly separated at a spookily great distance, what causes the particle 'furthest away' to change its spin from down to up?
