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 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.
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.
Damn, imagine if they’d given him two minutes.
What good would it do to give two basic explanations when you can just restart it?
I still wouldn’t get it

@@spunkymunky9286 lmao that’d be great
Brian's gift is that he never tries to make himself sound smarter than you in his explanations. No hubris or ego at play.
Seems like a lovely human.
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.
I have a profound urge to understand the world
What sort of math should I focus on? I’m learning calculus 1 at the moment.
@@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 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??(
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.
The ability to explain complex ideas in simple terms is a skill we should all strive for.
On that level he just gave birth to a turd, though. ;-)
It’s also sign of high level intelligence

@@joeg5265 everything if you know pls help
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 😅.
Great! Now explain quantum entanglement.
It was so hard to understand quantum mechanics before, but I understood quantum mechanics a little bit!
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.

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.

In quantum mechanics the physical system is described through a wave function whose evolution over time is determined by the Schrodinger equation. The wave function represents infinite different possible results for the physical quantities related to the system, but when we take a measurement, only one of these infinite possibilities becomes real; after the measurement, we must therefore modify the wave function “by hand” to eliminate all other possible results, and this modification is called the “collapse” of the wave function.
The fundamental problem with quantum mechanics is that interactions among particles are already included in the Schrodinger equation and such equation does not predict any collapse. The collapse of the wave function is a violation of the Schrodinger equation, i.e. a violation of the most fundamental laws of physics and therefore the cause of the collapse cannot be determined by the same laws of physics, in particular, it cannot be determined by the interactions already included in the Schrodinger equation. The Schrodinger equation is what allows us to make quantitative predictions about the outcomes of future measurements; everytime we make a measurement, we receive new information about the system, and we need to "update" our wave function, i.e. to collapse it, otherwise the Schrodinger equation would provides wrong predictions relative to successive measurements. After one century of debates, the problem of measurement in quantum mechanics is still open and still represents the crucial problem for all interpretations of quantum mechanics. In fact, on the one hand it represents a violation of the Schrodinger equation, that is, a violation of the fundamental laws of physics. On the other hand, it is necessary for the laws of quantum physics to make sense, and to be applied in the interpretation and prediction of the phenomena we observe. This is the inescapable contradiction against which, all attempts to reconcile quantum physics with realism, break.
Quantum mechanics is incompatible with realism (that's why Einstein never accepted quantum mechanics); all alleged attempts to reconcile quantum mechanics with realism are flawed. Quantum mechanics implies that physical reality (the universe) consists of the collection of all observed phenomena and such phenomena do not exist independently of consciousness. In fact, the properties of a physical system are determined only after the collapse of the wave function; when the properties of the system are not yet determined, the system is not real, but only an idea, a hypothesis. Only when collapse occurs do properties become real because they take on a definite value. It makes no sense to assume that the system exists but its properties are indeterminate, because properties are an intrinsic aspect of the system itself. The collapse represents the transition from a hypothetical system to an actual system.
The collapse of the wave function represents a non-physical event, since it violates the fundamental laws of physics, and can be associated with the only non-physical event we know of, consciousness. Therefore, the only consistent rational explanation of the collapse is that it occurs because consciousness is involved in the process. However, the fact that properties are created when a conscious mind observes the system in no way implies that it is the observer or his mind that creates those properties and causes the collapse; I regard this hypothesis as totally unreasonable (by the way, the universe is supposed to have existed even before the existence of humans). The point is that there must be a correlation between the collapse of the wave function (=violation of the physical laws) and the interaction with a non-physical agent (the human mind); however, correlation does not mean causation because the concomitance of two events does not imply a causal link. The consciousness that causes the collapse of the wave function must be an eternal consciousness, that is, a conscious God. This is the idealistic perspective, which implies that physical reality exists as a concept in the mind of God who directly creates the phenomena we observe, according to the matematical models through which He conceived the universe (the laws of physics); the collapse of the wave function is a representation of the moment when God creates the observed phenomenon. This is essentially the view of the Irish philosopher George Berkeley, and in this view God is not only the Creator, but also the Sustainer of the universe. Idealism provides the only logically consistent interpretation of quantum mechanics, but most physicists do not accept idealism because it contradicts their personal beliefs, so they prefer an objectively wrong interpretation that gives them the illusion that quantum mechanics is compatible with realism.

Brilliant!
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?
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.
Feynman also said in an identical situation: «Listen, buddy, if I could tell you in a minute what I did, it wouldn't be worth the Nobel Prize.»
Literally everything that was said in this video can further be shortened to very short and also very useless sentence:
Particle is described by it's physical properties such as it's location, moment of time, mass, momentum, etc
Chance of particle hoping from one place to another is calculated by adding up chances of all it's different possible paths.

There is a nonzero probability that you can walk through a wall. The particles that constitute the atoms that make up the wall, would have to move in just the right way and you could try from now until the end of the universe and never succeed. But the probability is not zero. That’s quantum mechanics.

Thanks for this thought process
What's the probability you make it halfway and they move back so you and the wall become one?🤔
@@Juan-dc6yf i think it would be even more likely to be stuck in the wall than to go through it😅
But why?
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.
I've watched hours of videos to explain this but couldn't in the end. This guy nailed it in less than a minute!

Why would a solution to Kolmogorov's axioms shock me? At the core this is simply Pythagoras at work. The old Greek would have understood quantum mechanics, if they had been shown the geometry of it. :-)
Quantum Mechanics were the only lectures I never missed in my Physics degree, found them absolutely fascinating, took as perfect notes as I ever took. Thought I understood it really well but could I ever get the calculations to work and give me the right answers? That would be a big fat "no".
There were the ones I hated. Never understood much of it (didn't need to either). And I understand even less when, say, BBC or quantum computer fantatics try to popularise it by their far fetched analogies.
I had the same problem with deep learning.
How's it going now?
I just saw a video with Einstein explaining E = MC2
Is this the same?
You just need some renormalization shenanigans 😂
He has more shine on his face than my future!
Feel sorry for you than! :D
Lol
Do not study quantum mechanics. It makes you forget to wash your face.
lmfao someone please parody this interview
Your future must really suck, because I saw loser reflecting towards your direction.
"You have 1 minute to explain quantum mechanics"
Brian cox: *sweats profusely*
*explains quantum mechanics in 60 seconds*
RUclips: Here’s a 30 second ad
Me: GOD DAMN IT!
I use Huawei phone, so no ads for me and i can even play youtube in the background 😎
@@navish1909 your all data for no ads
Fair deal you say?
Schrodinger's Cat Litter!
Congrats we all are now PhD in quantum mechanics. Update your resume and apply in NASA
Foxy nope. Particles can be waves, or waves can be particles. Depends on observer.
Except for you. You still clean toilets.
@@joelklemann9841 how do you know?
Well NASA isn't going to hire a PhD in Quantum mechanics
Indians obsessed with certifications and phds ... No wonder pathetic country
Our great ambassadors and explicators of the wonders of modern Science.
I watch this video in my high school then in graduation then after doing masters in physics everytime i learn something new.
One thing I learned. Real scientists don't comment on YT vids.
Whistler4u Nonsence.
Rob Degrey You mean Nonsense? Thanks for proving my point.
Whistler4u aha Im a real physicst here, look how angry all my comments are XD Rob Degrey I've seen your other posts I dont believe u know phys for a second
Nick Sumner And your point? At what time did I say I was a physicist? btw You're actually a stalker too...
Whistler4u Late night? Yeah using the term stalking so damn loosely, I can't help it those messages were at the top of the comment page jeez...
And read into what I said, I don't think I was angry at you nor calling you a physicist. Everyone else here thinks they're one and you seem to point out some truth to how egocentric everyone's being, so grats I actually think ur alright.
Brian is an amazing man. Knowledgeable, well-spoken, and a great speaker on scientific issues.
and played keyboards for D:Ream.
terrific actor too
Incredible
He always smiles all the time. Either he is crazy or very smart and happy.
This is what is so compelling about physics in general. We start with fundamentally basic principles of things like mass, energy, inertia and build ever more complex relationships between them to explain the universe.
Quantum mechanics is still elusive to me, but I appreciate an expert starting with a singular concept of the Path Integral.
You tried so hard with the vocabulary lmfao
@@jpmcfrosty I'm an engineer. Newtonian mechanics are really straightforward. Quantum is not.
@@petrichor3647 Alright, mate. Me like simple motion. Newton friend. Quantum strange. Smart man make hard topic less hard. Thanks, smart man.
Upsetting people think you’re going over the top with vocab 💀 I’ve seen people throwing in long words they don’t even understand before.
It's elusive to me why the Path Integral would make much of an impact on your understanding of QM. He outlined just a calculations technique.
This guy makes more sense on a complicated topic in 60 seconds than my group do in our 15 minutes presentation :)
Yeah because you go to a state college and not private so it’s going to deaden your mind
That's because his IQ level is 183. The average human IQ is 100.
@Lizzie McGuire Had a crush on you as a kid
@@alexk3469 they really arent much different from each other depending on the major youre going for. also he never said he goes to a state college. but maybe you did.
My friend Gus is a quantum mechanic. He does a great job on my Capri everytime I take it to his shop for a service
I have no more idea now than I had prior to watching this, but I've lost a minute twenty seconds of my life I'll never get back.
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
Or for most of us, “How to impress your friends in 60 seconds by pretending you understand quantum mechanics.”
😂🤣😂
Literally this
I just add the word quatum to everything and make quatum sentences with quantum grammars
@@Shinji17 🤣🤣🤣🤣🤣
spotted Fake
I am a quantum mechanic for my cars and bikes. I work out the probability of whether I'll know where to even start on a repair or maintenance project...
His voice is so reassuring and demeanour always so calm and charming. I wish I had a maths or science teacher like him. Although looking back I might not have appreciated them.
He is like damon (ian somerhalder)
Don't dwell on the past, think about the future! Things Can Only Get Better!
@@imaweerascal that’s not true if a nuke drops then things will only get worse hour after hour
@@adamatch9624 It was a joke. Brian Cox was in a band called D Ream, they had a hit called 'Things can only get better'. Weird but true.
@@imaweerascal He played keyboards for the band Dare too.
Brian lost me after “well, the most basic version is….”!
The good old days before everyone thought it was so cool and trendy to start sentences inappropriately with "So"
😂😂
@@richardmacpherson2
So, what?
🤣😆😂
Brian lost me and thousands of others when he started spouting his anti-Brexit garbage. Just another pathetic Liberal littering our education institutions that has never held a proper job. Never again will I listen to anything of his.
Now that I know that , I can go on with my life with the full understanding that I will need this information in case I critically need the location in the room of a specific electron .
Well I’m glad we cleared that up.
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 😂
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.
Quantum mechanics is *much more amazing and mind blogging* than this one minute single example explanation.
Yes, but since you didn't listen in high school you don't understand it. ;-)
Utterly amazing. We had brain cox for a paid business presentation but nobody was interested in the subject. This is the stuff we wanted to hear. A teaching genius.
Now I understand what my dog hears when I speak to him.
Hahaha so true
nice analogy
Normally, before you shoot an interview, you would powder the subject's face so he doesn't look like he took a shower in Vaseline before you started filming.
Dr Shaym Yeah, normally done when the interview is on screen. This is radio. No one gives a fuck how you look.
u r the guy from red letter media
Does that offend you ?
Radio?! Then why did they shot it it HD and posted in RUclips?
RUclips is radio now? Also the lighting and other elements in the room suggests a video "version" of this interview was intended.
It is a simple explanation but it's like telling someone who never saw a machine or even a wheel what a car is. Its something you sit in with four round things that takes you from point A to point B.
Einstein: "Spooky action at a distance".
I've watched all the videos about quantum mechanics on RUclips 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
Read the comments below for an explanation of Quantum Stupidity in under 60 seconds. 😀
And this is one reason why we love Prof Brian Cox.
These tw3o are my favourite physicists. Jim Kahlili is so good at explaining theory. Cox draws you into it's fascinating field.
If everybody in the world smiled like him. So contagious.
Brian’s youthful appearance is one of the mysteries of the universe.
No, it was one minute exactly: from second 14 till minute 1:14. That was a very elaborate and easy to understand explanation. Well done Brian. I wonder how Jim would've answered in under a minute. Much more succinctly I expect.
Brilliant!
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 😉
I watched this video in slow motion, I smiled deeply
who’s there after watching oppenheimer
“it’s a simple rule”
-Brian Cox
"It's not a lie if you believe it"
-The great George Costanza.
"Easy for you, difficult for me "
-Skipper.
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
