Boris Podolsky was a prominent physicist known for his contributions to quantum mechanics. He is best recognized for co-authoring the famous EPR paper in 1935 with Albert Einstein and Nathan Rosen. This paper introduced the concept of "quantum entanglement," which sparked significant discussions and debates in the field of physics. Podolsky's work aimed to challenge the completeness of quantum theory as it was understood at the time. He argued that if quantum mechanics were complete, it would imply "spooky action at a distance," a notion that troubled many physicists, including Einstein. Podolsky's ideas continue to influence discussions in modern physics.
