Einstein's Nightmare | The Secrets Of Quantum Physics | Absolute Science 4.5

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?

Thank you, I finally understand Quantum theory and Bells probability equation and find it a little disconcerting that it is correct!
It's similar along the lines of Schrodinger's cat experiment!
Nothing is as it seems, until you view it!

like magnets, what ever the photon's position is, it's partner is opposite

I am 5 years too late.
This video needs to be shown to every student who's in school.

this proves that the flying spaghetti monster is real. We are all entangled in his noodly appendages

When I was much younger, I had little problem understanding relativity, or so I thought.
But quantum mechanics, I thought completely bizarre! But as a chemist, I had to use quantum mechanics and got used to the craziness. To me quantum mechanics is still crazily bizarre, but the calculations I struggled to perform worked.
I did not have to understand QM to use it, but understanding will bring greater discoveries in the future. A retired chemist.
Thank you for your discourse!

I love the Evil Dealer illustration. Hahaha

We don't even really need to watch the video!
The REAL professors are all down here lol in the comments section!! 😂

Amazing how interesting this is to the point I didn’t even relize it’s an hour long

I love Prof Al-Khalili's documentarys, he has a natural talent as a teacher (as well as his expert qualifications ) and he make the programs fun and entertaining. Please BBC keep showing more of Prof. Jim's science.

This is a great video. Nicely produced. Insightful analogies. Couldn´t recommend it more!

I wonder if simulation hypothesis could help quantum physics become more digestible.

It's all esoteric, but I love it. It makes me look smart.. even though I can only dream to understand it. Good stuff; and I'm thankful for the existence of this content and easy access to it.

If only i could train my brain to love math, because then I might begin to truly understand what theoretical physics is like and its wonders. Strangely enough I could not get enough of these great videos.
