British physicist Brian Cox is challenged by the presenter of Radio 4’s ‘Life Scientific’, Jim Al-Khalili, to explain the rules of quantum mechanics in just a minute. Brian succeeds; while conceding that the idea that everything is inherently probabilistic, is challenging. Even Einstein found it difficult.

Ultimately, it’s much less glamorous than people think — but also at the same time more surreal, just not in the way people expect.
They (well, some folks, particularly to charlatans) expect something surreal in the sense of consciousness, the power of your mind, etc, etc.
In reality, the surreal part has to do with how particle move in some very peculiar ways, i.e., not akin to anything that most people would picture from their everyday experience.
And ultimately all effects can in principle be derived from these new ways to move from A to B.
Example in the context of atoms. Electrons orbit around protons. In normal physics, the electron can sort of be anywhere around the proton, kind how planets can be anywhere around the sun. But these different movement laws in the quantum version of mechanics put constraints on locations at which an electron can be found. So when it gains or lose energy, it has to respect these constraints, meaning it can only lose or gain energy in specific ways.
The analogous of this would be a car whose speed has to drop in steps, like going from 30 to 20 to 10, etc.
And roughly, roughly speaking that’s how you can get a laser: you have a bunch of atoms all changing from some configuration B to configuration A (again, because of the constraints of this new mechanics), so all of them emit the same color (the energy is determined by the color). That synchronous release of the same energy is a laser.
Thank you
Whats going on with his neck?? Notice the area where his shirt meets his neck ! Its like he is wearing a mask
So these little "hopping" particles have location in space "probabilities". What part does consciousness or observation play in the shifting or directing of these "probabilities"??? After all, recognizable patterns such as flowers and bees etc., are made up from these little "hopping" "probabilities".
Then Brian says off camera, "But unfortunately….it's wrong so we need to start over since we never got the concept of magnetism correct to begin with. Our bad."
So quantum mechanics is just a probability. Did I get this right?
Steve Rogers: Speak English 😆
Clear as mud to me
my stupid ahh wont be able to say abcd if someone asked me something like that
👌🏻
He just explained quantum mechanics in less than 2 mins. Ever heard of Immersive Translate?? It is a tool with meticulously crafted prompts, that allows translations in the technology field become more accurate and professional.
He said it succinctly.. it's about quantizing (measuring) everything and making bizarre predictions based on that.
I didn't understand a single thing but I'm pretty sure this mf a gay
so basically, he says, a particle in a specific location now, can be at any other location next, the probability is all possibilites,
I guess 2+2 is a thing.
So nine years on what do you think of the show so far and I’m talking about not so great BRITAN how does your quantum theory evaluate the perpetual negative demise of our society and a incontrovertible government
Famous for guessing
So what's a particle?!
A fascinating topic!
Mastering quantum science is indeed a crucial step towards understanding and potentially accessing the 4th dimension.
Here's why:
Quantum Entanglement: Quantum entanglement shows us that particles can be connected across vast distances, transcending our classical understanding of space and time. This phenomenon hints at the existence of higher dimensions.
Wave-Particle Duality: Quantum objects can exhibit both wave-like and particle-like behavior, blurring the lines between space and time. This duality is a fundamental aspect of quantum mechanics and may hold clues to accessing higher dimensions.
Quantum Superposition: Quantum objects can exist in multiple states simultaneously, which could be related to the concept of multiple dimensions or parallel universes.
Wormholes and Quantum Tunneling: Quantum science predicts the possibility of wormholes and quantum tunneling, which could be used to traverse or access higher dimensions.
However, accessing the 4th dimension, if it exists, would require a vast understanding of quantum science and its application to:
Exotic Matter and Energy: Creating or manipulating exotic matter and energy that can warp space-time and potentially access higher dimensions.
Quantum Gravity: Developing a theory that merges quantum mechanics and general relativity, allowing us to understand the behavior of gravity in higher dimensions.
Higher-Dimensional Mathematics: Developing mathematical frameworks to describe and navigate higher-dimensional spaces.
While we have made significant progress in quantum science, accessing the 4th dimension remains purely theoretical.
Nevertheless, the journey to understand quantum mechanics and its implications will continue to reveal the secrets of the universe.
Okay yeah I was stupid to think that
Brian Cox discovered nothing in his life, just smiling and give us no answers.
and get payed for this, this is the real mistery of our real dimension.
these things was discovered 100 years ago
Wow! Decided to leave a comment and noticed that I already did—- two years ago. My, how time flies. 😮
What is the probability of me understanding this??
Why don't you guys go up in outer space and video record in x-ray, UV, and any other part of the spectrum we can't see with out naked eyes and show it to the public? The people deserve the right to know just how bizarre our universe really is.
Quantum mechanics………imaginary science fiction. Make up shit to make people believe you know what you're talking about. No concrete proof of anything…
I watched this video in slow motion, I smiled deeply
My brain is not braning😓
Ahh 😭
😂😂😂😂😂 Insanity
that's pretty REJKF
But atoms don’t move as you would expect when observed. I believe light and time don’t exist together at all. Maybe estranged cousins in quantum physics at best, they should be studied as separates. We are getting closer 🤞🏻
