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.

[@WhoWho569]

@@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.

[@miguelalonsoperez5609]

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

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.

[@Ryan88881]

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.

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.

[@BuckWho]

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?

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!

[@canaanite23]

Haha brilliant. Thnx for that

[@gachalusaxxx.770]

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!

[@ncwordman]

@@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.

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.

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.

[@starfishsystems]

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.
