PBS Space Time explains the Bohr-Einstein debate over quantum mechanics and how quantum entanglement settled it. It covers the weirdness of measurement and nonlocal correlations.
Why Hacker News points people here: HN points to it as a clear, approachable explanation of quantum entanglement.

Clear explanation of quantum entanglement.

For anyone interested, there is a great video by the PBS space time channel explaining quantum entanglement here this video The thing is, although the quantum state of the photom collapses instantaneously on both entangled photons, we can't manipulate at which state the photon will collapse, and so, we can't really send information using quantum entanglement. We can't also confirm the entanglement until we can compare both measurement results or else we could send information from the future as in the quantum eraser experiment link Edit: formatting and typos

Some good related learnings: The Concept of Mass - with Jim Baggott (just watched this yesterday and it's reeeaalllyy good although basic): link Quantum Entanglement and the Great Bohr-Einstein Debate | Space Time: this video Measure for Measure: Quantum Physics and Reality (kinda old but still good): link Would recommend this order.

“The issue is that the measurement of the particle changes it - and changes the entangled particle.”
Explains the weirdness of measurement and entanglement.

Its... weirder than that. The issue is that the measurement of the particle changes it - and changes the entangled particle. PBS Space Time - Quantum Entanglement and the Great Bohr-Einstein Debate this video (and then watch the referenced Veritasium video)

“Einstein was later proven to be wrong.”
Covers the Bohr-Einstein debates.

Aside: Einstein (et. al.) wrote such a post (or a series of papers) as part of the Bohr–Einstein debates. Einstein was later proven to be wrong. this video
