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.

I now understand all of quantum mechanics. I’ll be available to collect my phd whenever it’s ready.
Be sure to show the math!

This is perfect. It usually takes much longer to prove that I'm stupid.

You clocked in around 10 seconds. Well done!
Good one 🤣
I’ve never been able to even remotely comprehend quantum mechanics, so I really have no idea why I thought a 60-second explanation would be of any help.
Ikr..im lost😂
I was thinking the exact same thing. No idea why I even bothered watching this
I think it was Feynnman himself who said "If you think you understand quantum mechanics, you don't understand quantum mechanics."
essentially it boils down to how everything on a smaller scale acts completely differently to anything on the macro ... and that it looks weird and spooky.
Like most of the readers, which means you think he knows what he is talking about. Well partially yes, partially not at all. The guy is more like a pop icon, with Michiu Kaku, Brian Greene etc.
I love how people with extreme knowledge are always so calm 💀
Only in physical appearance
ive never really thought of that but, its so true. i want to be calm! lol
And cheerful.
It's not that extreme knowledge makes someone calm (have emotional control and stability), it's that someone who is calm is more likely to listen, research, absorb and ponder (therefor gaining extreme knowledge).
We see the opposite of this all the time, mostly in political discussions - so many loud or uncalm people. They generally are the ones who don't know much of what they're talking about.
Cause they keep their thought in control or focused on what they want or they think is necessary , when you do that , your thoughts dosent control how to fake calmness or become anxious , hence they are taken care by subconscious or the devine or what some people call god.
He explained it in 60 seconds. I will understand it in ten years.
Or 20
if you think you understand quantum mechanics, you’re wrong
Unlikely, physicists don’t completely understand it. That’s why the door is left open
At least you are optimistic.
Ever consider the either??(

This guy is always smiling when he’s explaining things, it’s really nice. Wish my teachers would’ve tried it.
Mine threw chalk and eraser brushes
its called botox.
Lol And mine! But then again, mine had good reason not to be able to laugh. I once saw a female teacher get slapped across the face by a male student, one of the many bullies.
@@user-op9mv5lq1u Mine were simply not even there. In all fairness to them tho my school was way too problematic for any teacher to survive it, even less smile while at it. Public lower secondary schools in Portugal are hell holes, just as bad as they are in England, because of all the monster kids coming from troubled homes. Basically if you can’t afford a private school at least until your kids reach higher secondary level (which in Portugal is year 9) you’re better off home schooling them. To this very day I have no idea how I myself survived it. It literally felt like I had served time by the time I got to year 9 and could kiss the hell goodbye. So again, one can’t really ask of teachers who work under these conditions that they’re able to smile; they are after all human beings, not super humans. I have seen female teachers be insulted with everything under the sun before getting slapped across the face by students. One can’t really expect a person like that, who is really just surviving day after day, lesson after lesson, to be able to teach much. So less judgement on the teachers, and more basic understanding please. The public educational system is a failure, and teachers are the escape goats, cause the ones who show their face in the field every day are obviously the easiest targets to blame; when facts are that they too are suffering. Most of my teachers in lower secondary were on the verge of mental breakdowns. So much for the physics! I made the decision not to have children because I can’t afford a private school or to home school, and I will never, EVER, produce a child so I can then leave it in the hands of any public school system of this fucked up society. I was still having nightmare’ish dreams about that school until very recently. As a teacher I’ve been lucky enough to only teach in private schools (well I made sure I qualified for that) and the difference is just abysmal! The kids are so mature, well adjusted, sane, healthy and well behaved it’s incredible. It makes me feel for the teachers, and kids, that have to endure the lower secondary public school insanity even further.

That was great. Quantum Physics is really weird. It takes a lot of math. I went from knowing no physics and very little math, all the way through my bachelor's and master's, just so I could understand Quantum. Part of my study focused just on the giants of physics, in general, and quantum specifically. Brian Cox mentioned Richard Feynman. There are lots of great quotes by the big names in Quantum, but this one from Feynman is one of my favorites:
"If you think you understand quantum mechanics, you don't understand quantum mechanics.”
Here's another good one. I could go on and on, but this is the last one:
"If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet." Niels Bohr.
Okay one more, because I have so many in my head. This one is from Erwin Schrodinger (of the infamous cat thought experiment):
"I don't like it, and I'm sorry I ever had anything to do with it."
That one always cracks me up. He did the cat thought experiment because he wanted to show how absurd Quantum Physics is. But Heisenberg and all of them applauded him, and went wild for it, saying, That's it exactly! Poor Schrodinger. hehe!
Haha brilliant. Thnx for that
You know what? What you said is profoundly interesting, I was quite disappointed when you finished your word. I just started learning quantum(in high school) and it was so confusing and was even more confusing towards the end. That was hilarious and made me relate to Feynman's quote. But I like seeing quantum enthusiasts here and there on the internet, always having fun chatting over the Higgs boson or the probabilistic behavior of energy quanta with a random someone on the internet. What can I say? It makes sense, and it does not!
@@gachalusaxxx.770 "It makes sense, and it does not!"
Then you DO understand it! Congratulations. I think the main hurdle in Quantum is coming to grips with a completely different universe. We're talking about particles inside protons and neutrons.
These quarks and so on can basically slip through the "fabric" of space/time like water through a sieve. So they can be any place at any time. Time is hard enough to understand in Newtonian physics (with it not having any inherent + or - direction), and with Einsteinian Relativity (where it's "created" and governed by the gravity wells of massive objects).
But in quantum, everything is so near massless that gravity can't mess with it. And so the three dimensions of space don't know what to do with it either! These sub-sub-nuclear particles pop in and out of our existence, and so they can only be calculated by probability. And their size makes them do really weird things.
Above all else, I see Quantum Physics as an exercise in humility. I'm also really impressed you studied it in high school.
Do you have any advice for someone approaching learning physics with the desire to understand quantum mechanics?
I just turned 20 years old and have wasted my life and potential up until this point by smoking and partying. I need some guidance to catch up with my education.

@@jacka602 Hello, I don't know if I should even comment, because I'm younger and inexperienced than you. But I did want to comment to admire your need to change for the better. Not a lot of people have that kind of confidence and willpower. If you do want to start on quantum mechanics, I would definitely recommend going through 'quantum mechanics for Dummies', it will give you a broad beginning, and this channel Code Geek has a 11-hour course on quantum mechanics, it was pretty interesting, I would suggest you want to take a look at that. Calculus one is good, also take a dip at differential calculus, partial differential equations, and linear algebra.
Good luck on your journey!

if i had a teacher who could explain in simple terms the meaning and functions of certain principles of physics and math just the way brian cox did for quantum mechanics, I would have been an enthusiasts of deep learning a long time since childhood days. brian is a very good example of a very good teacher.
Brian Cox is not teaching, he’s divulging that is very different. The problem about quantum physics, or even Newton physics is one should study maths to real understand concepts without lack of information.
The art of divulgation is to explain something which arises from the mathematical formulation and give some common day life experience to have some intuition.
But one always loose something when doing so, there’s no magic ways to explain quantum physics or general relativity: if you want to understand them you have to study, otherwise you’ll never get the real thing and lack security when applying what you learn beyond the example in the video.
You can try perhaps Leonard Susskind courses or MIT open courses on quantum mechanics to have the basis of the theory: then you have good teachers, not divulgation
Simply put, 99% of math is shortcuts to adding and subtracting. Just shortcuts.

Brian Cox has done something that most people can never do. He has managed to hold onto that child enthusiasm we all had. Look at him. He's explained what's beyond most people's imagination or ability to comprehend and he did with the same look an excited child explains things to a parent or sibling.
If a child explained things this well, they were clearly the smarter adult
Hmm, It has been proven that only a small percentage of people don't understand quantum mechanics, and even less that don't get it when it's explained to them like they were 10. So I don't know where you get this "most people don't understand it". Must be from TV shows because they make it seem so. I mean, if you actually bothered to read something about quantum mechanics you would realize it's not complicated at all. The complicated and hard part is actually discovering something new about it. Understanding it is very easy.
Science has nothing to do with people's abilities and everything to do with their opportunities and their environment. Peer pressure, poor teaching, lack of resources, all play a part.

This is crazy. I've only taken one physics class, grasping only a basic level of understanding relating to the terminology. Yet, this was incredibly simple to follow and even made me excited to follow along while recognizing the logical consistency of the concepts he was introducing. Very nice.
Well, he's taken a particularly selective slice through the entire thing. By treating these quantum fields as if they were particles, he can describe them in terms of point locations in spacetime, and then, almost as a footnote, mention that the point locations have a probability of finding the particle there.
So far, it sounds just like classical physics, which is exactly what makes it intuitive to understand. That's because he doesn't mention what it looks like before measurement collapses the wave function to produce the specific particle. In other words, he doesn't mention what makes quantum physics unlike classical physics. And so he's glossed over the account of what is taking place in the general case, when there is no measurement to simplify things.
Everything that we think of as a classical particle is properly described as a field. A field in mathematics is a description of what values exist at every point in some kind of space. For example, if you take the ocean's surface as a 2D space, the wave height at every point on that surface could be called a field. So could the temperature, the salinity, and so on. This is still intuitive classical physics.
But in quantum physics the value of, say, the electron field at some point is the probability of finding an electron at that point. The field is spread out over all of spacetime, and there's just one field for all the electrons. It's like waves on the ocean surface. But there are no electrons anywhere in this field until some interaction occurs. It's all just field potentials. Those potentials are as real as the particles, but we don't know that directly, because we can't measure them without interacting with them and thus turning them into particles. That's a bit spooky.
@@starfishsystems I appreciate the time and effort you took to elaborate on the key details missing from this video. The format is inherently stress-inducing, which I now imagine lent credence to oversimplification (in regards to the speaker having 60 seconds to answer the prompt). The explanation you provided was concise, constructive, and accessible to a passive enjoyer of quantum mechanics like me. While I don't understand 100% of the information you explained. My concluding thought was still "damn, a lot of this seems like discerning and predicting the pretense of particles." Not sure if that thought means I'm on the right track to understanding this though 😅.

There is a nonzero probability that you can walk through a wall.

"If you think you understand quantum mechanics, you don't understand quantum mechanics" - Richard Feynman
carpy1970 "If Quantum Mechanics hasn't profoundly shocked you, you didn't understand it." -Neils Bohr
I don't think quantum mechanics understands me either. Perhaps we're not suited.
maybe because quantum mechanics cannot be understood mentally. Through intuition and looking at the big picture, it seems accessible tho.
IMO Intuition says _charm , up, down, spin_ etc... is all BS Emperors new clothes only.
If you want intuition's version look up Walter Russell or Tesla, Bill Gaede even.
Saying "Bill Gaede" has stripped you of all credibility. He is just a bitter old man who failed high school mathematics, who is on a crusade to remove mathematics from physics because he just can't understand it.
Here's my slightly longer explanation: Heisenberg's Uncertainty Principle states that we cannot simultaneously measure both the position AND the velocity of a particle. All we can measure are ranges of probabilities. The probability of measuring a particle at a particular position at a later point in time is governed by the Schrödinger Equation, which calculates the time-evolution of the "probability wave", aka, the distribution of probabilities at all possible locations at later points in time. Another way of calculating the probability of finding a particle at a certain position at a later point in time is using Path Integrals (this formalism was created by Richard Feynman), and adding up the quantum "Action" for every possible path the particle could have taken to get to that specific position. The Path Integral formalism is also used in Classical Mechanics, but is updated in Quantum Mechanics to use an Imaginary term in the Action quantity. Lastly, I will clarify that the uncertainty in the particles position is not due to a measurement limitation or a lack of knowledge, it is *true* indeterminism.
Why should one even care about "the probability of measuring a particle at a particular position at a later point in time"? Is science trying to predict the future of particles and how they relate to particles in the 'here and now'? And with all the infinite "space" that's out there, not to mention all that "time", how do scientists know where and when "a particle at a particular position at a later point in time" will appear to be able to measure it?

Path integral formulation uses Lagrangian to describe quantum mechanics (you can notice that when he said 'action'). The easier version of quantum mechanics is to use Hamiltonian, involved when you describe quantum mechanics with the Schrodinger Equation. Path integral formulation is more difficult since you have to know field theory, whereas solving the Schrodinger Equation is equivalent of solving a linear algebra problem.
Well, knowing field theory should be a given I think considering quantum physics is literally the quantization of classical field theory. And I do sense that you're correct because I have run into Hamiltonian mathematics numerous times but never this path integral thing. But I don't see at all how these specific domains (which seem mostly to just be disparate components of quantum theory rather than the core elements that define it) actually serve as any kind of synoptic explanation for the quantization of particle physics and field theory generally.

It takes a very smart individual to explain something with deep complexity in simple terms. These types of people make the greatest memorable teachers in life. We all had a few of them as we pass through our educational path.
Yes! I saw a quote that said something like “if you can’t explain it in a way that makes sense to a child, then you don’t fully understand it yourself”. I think the quote was attributed to Einstein but who knows whether that’s true or not 😂
Hmm, never saw it once in my life path, UNTILL NOW! Quite a revelation, I must say 👍
Load of tosh , next he'll be saying we're descended from ape's 😂
One of the best particle physicist in the world.
If everybody in the world smiled like him. So contagious.
Quite brilliant. I couldn’t get past how shiny his skin was.
it always is. Every interview he's in.
I was looking at the redness of his lips ...
@@remirec that's sensual bro
You can get there too, the probability from a to b, you have to calculate, multiple that by infinity, to the 4th power...now solve for x
I guess now that he has explained this simple concept, things, can only get better.
Winner
Haha...
Um no.
Only D-reams
I see what you D-ream there.
Hopping is an understatement.
1. Double hop, (wave self inference)
2. Hop only when you read my next position, (ask the Cat)
3. Complex hop (All Feynman diagrams)
4. Conservation if hopped, (charge, momentum,...)
5. Hop from nowhere, (Planck scale fluctuation)
6. Don't hop to here! (Pauli's order)

I love him, I went to a lecture in Manchester was alot more in depth than this. But he really makes it interesting for people that just want it simplified. Just draws more people into the field, witch is a great thing. (Yes I put witch instead of which get over it)

I failed my job interview last week but I repeated this line at the end and I came out feeling smart which was nice.
Great Explanation
I've watched all the videos about quantum mechanics on TH-cam in my quest to understand the concept. But I would have saved myself countless hours if I only watched just this video. Brian Cox managed to confuse me like all the other quantum mechanics videos, but he did it in under 60 seconds.
see my notes above. His example was a poor and over complicated example.
The most important part is that particles can hop around without ever being anywhere in between, but we cannot state with absolute certainty where they will be at a later time point. All we can do is calculate the future probability that they are somewhere else with a very simple equation. It becomes complicated though as soon as the situation gets complicated. But then we can calculate it on a computer given enough time and processing power.
What he forgot to mention is that particle can also be in all the positions simultaneously.
THAT's the doozy@@rohandavies8889
Sign of genius. Taking the very complex and making it at least understandable to the masses.
He quoted Feynman who was a great teacher and a theoritical physicist who would break down complex knowledge in a simple way

It is though he said it's just about mass, acceleration and distance which would literally describe the movement of any particular particle, then he states that quantum mechanics essentially studies the many probabilities of said particle being at any of these many particular points but I think it gets wackier at a subatomic level where things are quite frizzly.... I never studied quantum mechanics or looked into it properly but his 60 second explanation was anything but unsimplified

@@OTG414 sorry ….. that’s unlike me . 👍. Super clever bloke . Best 😁
I like them both, Brian Cox and Jim Al-Khalili. Physics is so interesting, and these two guys really do their best to present it to the world in a way that most people can understand it.
Brian: well Jim put it this way, you had hair and the probability of you having hair again is zero.
Jim: Very good
Tell that to William Shatner.
Jim’s bald head is more likely to get him a wife than Brian’s mushroom type cut.
Hahaha, nice😅
I could stop laughing for 60 seconds straight
but they are both bald 😉
For the F1 fans among you: He sure does sound like Chain Bear (Stuart Taylor).
As a Physics teacher, I find the sub-minute explanation quite brilliant. Will use it for introduction in my lessons!
To call this an explanation of quantum mechanics is a huge overstatement.
Dah! Do ya think?
Yes but you may need more than 60 seconds to describe it succinctly. ;)
you can do better right?
@@AlexandrBorschchev Of course not! My comment has nothing to do with Brian Cox, who is quite brilliant and entertaining. My issue is with the plethora of videos trying to simplify complex scientific concepts to the point of making them meaningless. Some things simply cannot be explained in simple lay terms. Watch Richard Feynman's response to a reporter asking him to explain magnetism.
I am Bangladeshi Electrical Engineer. I think your explanation is outstanding.
I think I just felt a breeze above my head.
buk1237 That was my nutsack :-(
😂😂😂
buk1237 How tall are you? I'm only 5'7" and I felt that same breeze.
At least that breeze coasted above your head and below my balls.
It was the breeze running from ear to ear through Brain Cox's head.
Simplicity is one of the hardest traits to master. Perfect.
Brian Cox and Alexei Filippenko seem to be two of the nicest people you would ever want to meet. They always smile and just seem to be jovial all the time. Being happy is infectious. Unfortunately so is sadness and anger. Watching Brian and Alexei smile all the time during an interview always gives me a reset of some sort.
When you're fully into a certain subject and you can look at it from a wide angle, you're able to explain it in simple terms.
“Describe quantum mechanics as fast as you can”
Gives an obligatory Feynman quote. Describes in detail what Feynman meant by it, then sums it up in one sentence at the end that he could have just said at the beginning. And STILL gets it in under a minute. Prof Cox is one badass physicist.
I disagree. He chose a poor over complicated example.
@@mathematics5573 You realise this was 2014 right? Feel free to post your uncomplicated example.
@@Mk1Male To all of you. A better way of explaining the basic rules of Quantum Mechanics in 59 seconds is The Heisenberg Uncertainty Principle.
The Heisenberg Uncertainty Principle says,"" the more accurately you know the position of a particle, the greater the uncertaintly over its velocity and vise versa."" This is the foundation of Quantum mechanics, and are its basic rules and are a total contradiction to classical mechanics, that allows you to determine positions, velocities, accelerations and momentum accurately, all at the same time. Classical mechanics break down at the level of particles.
Hope this is clear. Brain Cox's example came a generation after Heleisenberg l. And is a poor and over complicated example.
I am a chemist and physicist.
@@mathematics5573 You seem to have a very big opinion of yourself. Never heard of you but have known about Prof. Cox for an awful long time.

The core concept behind explaining something is to make someone understand.
It's a party of concepts. Can one idea prove another idea to be its own point of reference? Don't forget since the beginning of language, consciousness has stuck shiny labels on its world. Science no less is an activity of consciousness and self discovery.
a fun thing to do with quantum computing is related to spin, and angular
momentum, I’ve read its kind of math metaphorical to compare newtonian
spinning bike wheels to quantum spin, I saw a video where a guy had two
bike wheels on an axle, on a rope, where he could spin them same
direction or opposite directions, spinning same direction they turned
horizontal and had precession, they had a particular spin, when the two
were spinning same direction they omitted going horizontal and just went
vertical, now with quantum entanglement or linkage of 18 photons to one
other photon, or one electron, you can have all of them spin up, and
the main one actualizes nonfractional spin up, then if you you have 9
spin up, and 9 opposite spin up they balance bigly, and perhaps the
quantum actualized state of the photon is durably undecided or
indeterminate (longer compute interval! Less unwanted environmental
disruptability/stabler quantum computers!) along with perhaps causing
increased compute time or computation resolution, “cylesishness” this
could be a new third quantum bit besides up and opposite of up spin, so
you get 3 factorial states, making quantum computing more effective per
module. also, if fractional ratios like like 4:14 are resolvable or 7:9
then you can get like 2^18 bits, or something, per quantum superposition
compute element, really heightening quantum computer capability.
tell me what you think of this quantum computing idea/note, if you think it
has merit pass it along to engineers and scientists. The idea is public
domain. I'm Treon Verdery.
Well Jim, a particle disappears in a place called A, and then has a reasonable probability to appear in a place called B, but that probability is 0 if the particle is a hair follicle and both places A & B, is your head
From his explanation, which was brilliant by the way, I gathered - it is the calculated probability of a particle being in different positions at any given time or structure.
Based on where it is now.
It was so hard to understand quantum mechanics before, but I understood quantum mechanics a little bit!
Dr.Brian cox explains complicated things like a enthusiastic happy kid and that make it more interesting to hear and simple to understand.. Nail and brian cox r two gems❤
Great to see Rafael Nadal explaning quantum mechanics
That's being verrrrry generous to Brian LOL
tim wheeler
I used to watch him in television when I was so young,Brian Cox is always charismatic! (his way of interpretation isn't overly exaggerating)
For the benefit of anyone wanting a "proper" short explanation and confused by this, all Brian explained here is that QM is probabilistic. If you want a bit more, here's my best effort:
The thing that really makes QM quantum is that those probabilities are calculated by adding up lots of wavelike amplitudes, which can reinforce or cancel each other. In "classic" QM we add up a finite number of special amplitudes, or "wavefunctions"*. The other key feature is how physical measurements are derived from these amplitudes -- making a measurement breaks the wavefunctions into components (called "eigenfunctions") specific to the quantity being observed, each one of which has a special value, the "eigenvalue". Each time the measurement is made, the observed value will be randomly chosen from the discrete set of eigenvalues, according to how much their eigenfunction overlaps with the total wavefunction. Since the eigenfunctions are specific to the thing being measured, not all observables can be measured at the same time: this gives the Heisenberg Uncertainty Principle.
* The Feynman path integral and action mentioned by Brian are actually a step up from this, which say that the number of such amplitudes is infinite: this is key to the more advanced Quantum Field Theory.
Our great ambassadors and explicators of the wonders of modern Science.
You lost me at particle
Love Brian Cox, he just explains things in a way that’s not overly complicated so you can understand it but he actually makes it fun to learn science. Really liked his series he did which was 7 wonders of the solar system or universe but it was factual and I actually learned a lot just from watching him, plus if you actually have an interest in that stuff it helps as well 😂
yes I've just watched these Series too. Love how he explains stuff in a way you can grasp. He uses good examples. Makes science interesting
