BORIS PODOLSKY MEMORABILIA |

Hello. But first, I want to say a few words about why Podolsky is famous. In 1935, together with Albert Einstein and Nathan Rosen, Podolsky wrote a technical paper called, "Can Quantum Mechanical Description of Physical Reality be Considered Complete?" This modest document predicted that, if a certain experiment were performed, the result would prove the physical possibility of something that came to be known as "action at a distance" — a term that implies simply that a causal event that takes place at one place in space-time could have an instantaneous effect at another place in space-time — no matter how distantly the two locations might be separated. This prediction contradicted the common understanding among physicists of that day that the effect of a causal event could propagate, or travel, no faster than the speed of light. Unfortunately, in 1935 the technology necessary to perform the experiment described in the above paper was not available. So for many years the prediction was known as the "Einstein-Podolsky-Rosen (EPR) Paradox". It wasn't until 1964 that solid experimental evidence began to appear that the EPR prediction was correct. Although the experiments of Bell and Aspect are not yet totally conclusive, they are persuasive enough that the former "paradox" is now generally referred to as the "EPR Effect"; and the possibility of "action at a distance" regarded by most physicists as highly likely. The Effect also strongly suggests that the universe is encompassed by more than the four dimensions that are generally seen as characteristic of space-time — or that "hidden variables" are present everywhere. The latest theories of cosmology support this possibility.
