The story of quantum physics starts at the beginning of the 20th century with scientists trying to better understand how light bulbs work. This simple question soon led scientists deep into the hidden workings of matter, into the sub-atomic building blocks of the world around us. Here they discovered phenomena unlike any encountered before – a realm where things can be in many places at once, where chance and probability call the shots and where reality appears to only truly exist when we observe it.

From Wikipedia:
Jameel Sadik “Jim” Al-Khalili OBE FRS FInstP (born 20 September 1962)[2] is a British theoretical physicist, author and broadcaster. He is Professor of Theoretical Physics and Chair in the Public Engagement in Science at the University of Surrey. He is a regular broadcaster and presenter of science programmes on BBC radio and television, and is a frequent commentator about science in other British media.

Albert Einstein hated the idea that nature, at its most fundamental level, is governed by chance. Jim reveals how in the 1930’s, Einstein thought he’d found a fatal flaw in quantum physics. This was not taken seriously until it was tested in the 1960s. Professor Al-Khalili repeats this critical experiment, posing the question does reality really exist, or do we conjure it into existence by the act of observation?
Einstein’s nighmare was that reality had no fundamental existence a priori but was only what we observed. If we didn’t observe (or measure something), nothing was there. This documentary describes the nearly century-long battle between quantum mechanics and observable reality. It turns out that Einstein’s nightmare has come true. The battle has come to a conclusion but that leaves even more questions yet to be resolved.
