Professor Jim Al-Khalili traces the story of arguably the most important, accurate and yet perplexing scientific theory ever: quantum physics.

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.

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?

Elsewhere, we explore how the most famous law of quantum physics – The Uncertainty Principle – is obeyed by plants and trees as they capture sunlight during the vital process of photosynthesis. Could quantum mechanics explain the greatest mystery in biology - evolution?

Good documentary however, what’s up with the demon mask? 😂 just weird and totally out of place

If Einstein had seen the evolution of computer games he would have accepted that we live in a simulation.

I truly love that matter changes when we gaze upon it... Imagine a mothers love and how powerful those endless stares into each others eyes actually are and what is actually taking place in that moment.

I find it quite interesting that the World of Quantum Mechanics has this eerie spiritual feeling to it...oh look! The devil is here!
How peculiar that "Dealer" who you cannot beat and is also in charge of the quantum "realm"(or is it spiritual realm) happens to be represented by the devil....

You took three tries at six games (666 ??) and lost all(trying to out smart the devil but still losing).

Just coincidences I suppose, or is science finally admitting that its dabbling in the spiritual world?

"Edison's new invention - the light bulb." Obviously someone never heard of Tesla, which for me is really disappointing in such documentary.

Dr. Young who lived shortly after Newton, arrived at the double definition of Light, as both waves and particles. Newton like the particle theory because he hated the ideas of his rival who embraced the wave theory. This is a fascinating programme Dr. Al-Khalili, but the science/opinions need clearer dating. (And then there was Al Hazan around 1000 a.d.). And te analogy of waves of water with waves of light is not convincing since water is a dense physical element; light is not a dense physical material. But it does seem to have a physical contiuum; is the particle/quantum idea going back to Newtonian thought?
