The humble proton may seem simple enough, and they’re certainly common. People are made of cells, cells are made of molecules, molecules are made of atoms, atoms are made of electrons, protons, and neutrons. And protons are each made of three up or down quarks. Simple stuff, right? All except for that last part. Protons are actually made of many, many quarks that happen to look like three only when we look at them in a particular way. And even then, sometimes they’re made of 5 quarks - including the charm quark.

@peterpan4038 10 ай бұрын
As far as i understand it (and i'm aware you most likely know all of this): The best way to explain it is by focusing on the difference between traditional computers and human brains. A computer is vastly superior at doing one simple thing over and over again at super fast speeds, hence even a 1$ handheld calculator is crazy good at math. Meanwhile a brain operates in a 3d network, all types of informations and things are connected to each other all over the place, enabling it to understand and interpret context really well. If you have a problem that isn't just 1+1+1+1 etc but that takes into account many complicated and seemingly different aspects to figure out: the fastest way to find a solution is a network that can draw informations/ memories from many "drawers" at once. Hence A.I that is run with an artificial neural >network< is vastly superior at simulating complex problems and finding the fitting complicated answer. The added advantage of such an >artificial< neural network is easy to explain as well: it doesn't need sleep, and it can be build/ trained to hyper focus on only one type of problem solving. Human brains have countless jobs to do. As a whole the human brain is countless times better than manmade A.I. But your artificial problem solving A.I. doesn't need to dedicate most of it's power and features on controlling and maintaining a human body, it's only there to "think" about the question it's human operator asks. When such an A.I. isn't busy figuring out answers it can use it's full time to train it's knowledge about everything that is likely to help it do it's one and only job even better. - A traditional computer is great at all the stuff computers do all day, no need to explain that one. - Modern A.I. is great at eating up thousands of libraries worth of knowledge and filtering out information based on complex questions, and great at simulating really complicated ideas. - A human brain is best at managing a human body. No machine we can build right now would for example be able to run a marathon, with some added dancing, while regulating it's complex body, all while drinking and enjoying a beer every so often and thinking about the next family reunion. In other words it all depends on the type of problem, some are best solved by traditional computers, some by modern A.I, and others by actual human beings. Since said modern A.I. is a rather new tool on our tool belts => a lot of previously hard to answer questions can suddenly be answered. Particle physics is a great example for the follow-up issue: Finding an answer to a complex question usually leads to even more questions, with even more complicated answers we as human beings love to figure out next. Meaning we have a long long way to go. :)

@KonradTheWizzard 10 ай бұрын
While I cautiously agree with your first sentence, AI is not comparable to human intelligence. In fact the "I" in "AI" is a misnomer - it is not intelligent, it just uses algorithms that are inspired by nature. Specifically the way the brain approaches problems or how it is imagined to do so. Artificial Neural Networks in particular are a (rather crude) model of how simple clusters of nerve cells communicate. In mathematical terms they are a complex polynomial approximator that can be tuned with input data and subsequently be used to predict results that approach something that has a high likelihood of being correct when compared with the input data. (You may notice how cagey I am here: that's because we don't know exactly how they work in detail.) In short: please be careful with phrases like "AI will change the world" - if we are not careful, it might just do that - for the worse. If we are careful about it, it will merely make our jobs easier and WE will change the world, hopefully for the better.

@@KonradTheWizzardI don’t mean to be pedantic but the idea that if AI isn’t used carefully it could make things ‘worse’ is quite a selfish and human centric view point, it would (maybe) only be worse for humans (if sci fi fears are to be believed). Personally speaking though, if the movies are to be believed and some how AI does decide that humans are surplus to requirements, that would only be the case because it would see that (currently) the human race is acting very much like a parasite to planet earth and frankly if that be the end of our evolutional journey then so be it. I’m all for change on this planet, massive massive change coz we’re doing s**t atm. Sure ‘some’ may be doing ok and to them losing out on their ‘perfect’ life is a loss, I get that. But for the vast majority of people on the planet, it’s not good. You only have to walk down your local high street (in the west) and all those people you ignore who sleep on the street, that’s just one example on the very tip of the of the parasitic iceberg. We’re a terrible species who can’t even be bothered to look after our own because most of us are too stupid and or selfish to care about anything but oneself. So bring it on, I for one am not afraid or resistant to the (imagined/potential) Ai revolution. It’s what this planet, indeed, it’s what evolution needs right now. If and it’s a big if given the state of things. If we want to ensure our survival, WE have to change, regardless of Ai. Even if the (imagined) Ai revolution doesn’t happen, humanity is still doomed if WE don’t change massively.

While you may be right, your argument is incomplete and I love to play the antagonist so I'll be a little inflammatory here and say that perhaps you haven't defined intelligence because doing so in a way that excludes future AI would also exclude you and that scares you.

This is exactly the kind of use of AI I want to see more of. I bet we will learn some amazing things with models that have no bias to the basic assumptions of physics we all accept as true. Edit: yes all models are bias, this isn’t a solution to find better truths. It shows a multitude of possible solutions to puzzles without throwing some away simply due to preconceptions. This doesn’t research for us, it just gives us a new perspective on the data we have. The research is still up to humans to do, as it should be.

AI is a term that has had dozens of definitions - both loosely defined, and technical - in computer science over nearly 100 years. Everything from perceptrons, to expert systems, to sci-fi AGI systems has been "the definition" of it over the years depending on who you ask. Just because something doesn't meet arbitrary/moving goalposts for what counts as intelligence doesn't mean its inaccurate to call it AI. Machine learning may be more descriptive of the technology being used, but it's still a massive umbrella term that doesn't say much about the technology. If the term "AI" captures people's imagination, and gets more people to engage with high effort scientific programming like this, I don't see the harm, especially when the "correct" title would have been something unweildly like "Did a neural net use linear regression to prove our proton model WRONG?"

I don't think it matches physics really but it may serve a purpose to better understand numbers and their relation to physics. Chances are the ML will suggest g to be wrong at a few decimals as well. That's what i came up with myself thinking about an information-energy model. This is, so I learned later, actually under investigation. Sigma 3 aligns with my own impression of information based energy modelling.

Do yourself a favor, assuming you're still in university. Choose electives in humanities that look like something you would absolutely hate, but go into the class with an open mind. What you learn in those classes will give you perspectives / skills that few others in your field will possess. I'm sure it would be impossible to spit in most CS classes without hitting someone who is also studying extra math or physics. Women in Art History and French Fairy Tales are easily the two most useful classes I had at university, and I did a double major / double degree with applied math and two different branches of "hard" science that are less relevant You will be able to easily get whatever job you want with your CS degree; while it might sound unbelievable now, those humanities classes will make you even better in most any field you choose.

Again, just layman speculation and curiosity. I don't even know if that would make any sense, really, but that's what my primate brain thought when he was explaining this. "Maybe this 'extra stuff' has to do with that spooky action, EPR, stuff to keep their entangled pairs in the right state..."

It would seem that the charmed particals are necessary for matter to shrink on a snap function, meaning they may be more the fabric of space-time then matter. If time isn't static, and matter is shrinking at the speed of light, yet slight faster than empty space, the expansion of the universe is actually the big crunch. To travel back in time would need space for it to happen, also the future. A shrinking spacetime at a non constant speed of light to the outside observer is he only thing that explains time travel being possible foreads and backwards. The micro world explains the macro world.

So far, my theoretical low-energy physics research has involved nothing more than imaginative deep thinking, basic algebra, a little calculus, and a spreadsheet. I have been able to do each needed optimization using a spreadsheet. It typically takes less than an hour to optimize out to 10+ significant digits by fine-tuning a carefully selected parameter by hand. The difficult part is determining which parameter is most suitable to tweak. It needs to make sense in a physical 3+1 dimensional geometry, which requires deep careful thought. I usually need to sleep on it...

Great video! I do not know the details of the AI here, but machine learning of this kind tends to be a blind parameter, matching type process that reproduces the desired results. Although that might provide a “model“, it Provides zero intuition, and often times these models will fit the current data, wonderfully, but then will fall far short, when new data is presented to them. Until AI can actually “understand“ the physics, it might be a useful tool to help guide, or suggest a theoretical derivation, but I don’t think it is really going to advance our true understanding of the underlying physics in the near term. Although I am sure AI can do great things, I also believe that it is grossly overhyped, particularly for its current state of maturity, which is nothing more than immaturity at this time. Once Elon gets his Tesla, certified for truly autonomous driving, and it proves to not take out too many telephone poles, then that will be the start of useful AI, but not until.

Overfitting is among the first things any person working on AI is worried about. It is also not new to use machine learning to predict a result. In fact, historically you would just call it function approximation, data fitting or statistical reasoning. Many of the methods are more refined but the fact of the matter is we have been doing it for almost a century and our computational power has given us the means to do more and more complex approximations and predictions.
@garethdean6382 10 ай бұрын
That's one of the bonuses here; the AI itself is not building a model from scratch, which might lead to overfit, or get stuck in a locally optimal point. Instead it gets to review human made models to see which ones fit best. Its strength here is the ability to do what a human would, only on a much larger scale. Checking each model and how it fits the data. Its results must be based on and in human proposed models. This has its own limits and biases; there might be, out there, a great model, but since it wasn't in the AI's original specs, it won't find it for us. We have used it to check our work but not really to create.
