The Secrets Of Quantum Physics: Let There Be Life (Jim Al-Khalili) | Spark 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?

💬 Comments on the video

Heisenberg, Schrodinger and Ohm are in a car
They get pulled over. Heisenberg is driving and the cop asks him "Do you know how fast you were going?"

"No, but I know exactly where I am" Heisenberg replies.

The cop says "You were doing 55 in a 35." Heisenberg throws up his hands and shouts "Great! Now I'm lost!"

The cop thinks this is suspicious and orders him to pop open the trunk. He checks it out and says "Do you know you have a dead cat back here?"

"We do now, asshole!" shouts Schrodinger.

The cop moves to arrest them. Ohm resists, because he doesn`t know how to conduct himself.

Evolution make s alot more sense when you calculate considering epigenetics.

I could listen to Jim all day. He’s so wonderful

Is it necessary to have such loud background music? I know it might seem weird, but I often prefer to hear the words spoken by the actors.

Probably an awesomely informative video, but 10 commercial breaks is unacceptable

this makes me appreciate life so much more. thank you

So this means that all biological systems are using quantum tunneling and entanglement, and plants use the uncertainty principal, in order to work with enough efficiency to work. But is it possible for the consience to fully understand.
That's what I wonder. I m saying that our entire mind understands but our consience has to have it taught to it using language.
This would mean that we have a mind within a mind.

btw, good science doesnt need a synthesizer backing track.

I just had a thought,
What particle's vibration I'm smelling when i smell a metal rod for example?

As I understand it shouldn't so much material decaying for being able to smell it so often without a visible "erosion", isn't it?
Is by any chance air picking up the vibration of objects it get contact with?

You can easily think particles of grass/pollen or others travel to your nose, but it's not so obvious with a metal.

Insights anyone?
