You don't have to understand everything, but it's good to have a glimpse of the future

https://www.nature.com/news/quantum-spookiness-passes-toughest-test-yet-1.18255 here is the 2015 article about the Entanglement mentioned at 24:39

Here an explanation of the Quantum Entanglement https://en.wikipedia.org/wiki/Quantum_entanglement and Einstein's position. I think that saying that Einstein "HATED" the Q.E. is a bit excessive, he simply believed it was not possible and qualified as "spukhafte Fernwirkung" . I get allergic whenever someone tries to ridicule Einstein.

Here more about Einstein "spooky" story https://en.wikipedia.org/wiki/Bohr%E2%80%93Einstein_debates and here https://en.wikipedia.org/wiki/Qubit something more about the Qubit

This is also a good presentation of the brilliant Jaya, given to a totally passive and indifferent audience ("we don't really care if the NSA spies on us, all we care is make good money and have fun on the weekend")
