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 artificial 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. :)

An absolute great use and application for AI! I recall when I was in college (engineering) hearing about the discovery of a thing called a "quark" and the buzz it created. We've come a long way with still more to go. Great video. Thanks.

Incredible episode. Had to pause and rewind multiple times to understand some parts, but mostly due to me going "wait, that can't be right, let's listen again". Thank you, it was amazing

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.

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.

I did enjoy this presentation. I found it very informative to the lay person. Of course, there is probaably a hundred thousand hours of more and greater indepth information. As a last point, in a different video, you might explain why the weight of a sub particle is measured in electronvolts as opposed to pounds/ounces. I have explained this as the amount of energy contained when using energy to mass conversion. I could be incorrect in my explaination so coming from a physicist would be much better. Thanks for the video.

I like Star Talk, but I love Space Time. Great work, as always, Space Time team😊

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?"

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.

This is really cool. We have done one of two things. 1. Found a new way to better discover what the universe has to teach using AI. 2. Found a more efficient way to create even better delusions taking us even further from a theory of everything. Either way, I found this episode brought my hopes up, then let me down. Ultimately, I was just a little charmed. What a strange experience from top to bottom.

Underrated comment

If Charm-antiCharm collisions do happen inside Protons, it seems like that would allow for Protons to decay if their interaction were to happen unevenly or otherwise linger on fractionally long enough to cause the proton to destabilize.

Spontaneous (not in a particle collider) proton decay is a major prediction of several theories in physics, and String Theory IIRC, however every experiment performed to detect it has never found a single proton decay.

@@stevenverrall4527 After reading and re-reading your abstract, looking up concepts I had no clue about... can I just ask for a cliff's notes version?

This channel is awesome. So dense with material I feel like I’m kind of taking an advanced class in physics. Not that I’d know, I’ve never taken physics. Still pretty cool though trying to figure out what makes up our universe.

This is the best video ever on elementary particles.

The Extrinsic particle concept sounds like the doubts I have had for over twenty years over what all these "Atom Smashers" could ultimately reveal. I have long wondered if the collider approach is just creating tinier and tinier energy conformations that do not exist otherwise.. All the way down to the Planke length:-)

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.

Oh thanks I really appreciate the advice and it's good for others who find this. But I'm actually going back for my second BS in CS. I did biotech first time around and ended up hated being in the lab, so here I am. I did end up basically doing a creative writing minor during that first degree, so i completely agree. Humanities are so useful, like I've been consistently praised for communication skills at my job thanks in large part to how much writing I did. That's not even to mention all the ways it's probably just helped me stand out but thinking flexibly, or something, that I just haven't noticed

It would me more helpful if also give us some link to the mentioned papers

I love this channel. Well made with no sponsors

I learned something new. Thank you! Very excited for the future with AI.

Is there a link to the paper that can be shared in the video description? Would love to know what kind of AI modeling was used here.

This was reallly good, thanks for sharing

The reason matter and energy are equivalent in particle collisions has to do with the geometry of the particle. Billiard ball? Standing wave? Something else? How does a billiard ball, or whatever it is, store and exchange energy?

Amazing video, as always. Maybe, one day, AI will help us understand things like 1/137 or quantum gravity similarly. By analyzing relationships between scientific observations we've collected over time, maybe it will see something we've been missing all along. Also, loved your appearance on StarTalk! Keep up the awesome work.

The proto-virtual neutral pion in the 2023 paper "Ground State Quantum Vortex Proton Model" published in Foundations of Physics on January 23, 2023 could perhaps occasionally transform into a charm-anticharm pair. Note that the two charge shells have the same charge structure as five quarks.

@@denysvlasenko1865 In my opinion, low energy physics is set to become an emerging scientific frontier. I also think that human creative thinking will outperform any supercomputer or AI system. 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... I could fully automate each needed optimization process in software, but it would take me far longer to write and debug the code than to simply do it by hand (with a spreadsheet). Of course, the spreadsheet rapidly recomputes all the parameters for me.

1. Uncertainty is the only certainty, maybe. 2. Mass is "normal" matter's energetic resistance to acceleration. Quit thinking of mass as a kind of weight. It's a kind of energy. 3. IMO, The medium of the galaxy is involved in all these particles and reactions, maintaining the intrinsic speed of light, and contributing energy to them. Thanks for a great and informative video!

Beyond curious to find out. This extends on the information modes i trained a public Ai testground with around 2016 or so. Essentially, the AI is likely to have made an information based model. 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.

Last time I was this early, the helium nucleus was just starting to form.

About the objectivity of AI: An AI is programmed by a subjective human. Therefore, an AI can also have intended or unintended biases towards finding certain results.

omg this is the 1st time that this guy went into an extremely complicated topic & i came out understanding it a little better. Previously he went over dark hole & alternte reality and halfway through i was so lost. I really liked the guy before this one. Or maybe it was whoever wrote the script who changed and thats who i understand.

From now on I will refer to my eyes as my “particle detectors.” Thanks PBS Space Time!

2:45 I know it's just a simple visual to show how the electron microscope works, but it really bothers me that the figure shows the electrons focused on the ant's thorax while the display shows it's head.

For the 15 minutes I watched this video, I felt a lot smarter than I usually do. Thanks!

i was about to say that there is negative energy inside the proton to compensate for the generation of the charm quark. the presence of negative energy could be lead to interesting ideas. like the interior of the proton is an indication of the structure of quantum vacuum. maybe this negative energy is the origin of dark energy.

That actually almost made sense! I finally have my head around MeV, and why it's relevant to this sort of work. Baby steps lol.

Thank you so much for these videos! The further I get in my PhD, I lose track of other fascinating aspects of physics
