The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

This is the kind of content that has a real impact on the current revolution in the online education. Clear, eloquent, well animated - a real gem for curious minds. Thank you for doing this.
no such thing as difficx or knowx or strugx or elox etc, say, can sx any nmw and an ys perfx
I was about to comment with a similar statement. I agree 100% and share the same appreciation.
Also check out PBS Spacetime
Yeah, it just feels like a gem to me 😁
To bad particle science has so many failed predictions.
When RUclips search gives you exactly what you were looking for. It’s new. It’s long. It’s well explained. Finally some good RUclips

"Finally, some _good _*_friggin'_* videos!"
you look and act like an angel. I feel sad I can not help in any way but sending good thoughts.
Usually I watch these because I am interested, but end up falling asleep because it just overloads me or the presenter is boring. This video managed to keep me awake and engrossed the whole time, and I learned a lot. Thank you!
The most craziest thing is that we are basically just that which is being explained, except the missing bits, that is trying to explain itself to itself. I love it
As a Physics student, I have to say that this is an amazing introduction to the standard model. This video deserves to be played at schools as part of their curriculum! It explains all of the important aspects in a simple way that upcoming students can easily understand. Thank you for your contributions to science communication.
Hey thanks!
Yes, it's an amazing indoctrination material. Sadly, there are just lies. There are no particles. "Particles" is just an idea in consciousness. Consciousness is all there is. I wish somebody told me this when I was a physics student too. Unfortunately, I had to waste years of my life through the indoctrination machine.
@@domainofscience des, really really well done, and I have seen a lot. Many public scientific comment state we almost know everything about the basics the Standard Model explains most, so we understand, how our world works. But actually, we merely deciphered most of the alphabet of partivle science, at least we hope. No idea, why we need 3 generations of quarks and leptones, no idea why they have the masses they have.
Do you know answers to?:
1. Do we actually know, how fast neutrinos are, since they are likely not without mass?
2. Why do we need to care about mirrored universes and if some particle would break that symmetry?
Thank you for your great work, inspired by kids. 😋 looking forward to my girl growing and being curious 😍😊
@@visancosmin8991 everything is " indoctrination ", what's your point,?
@@enoughofthis No. Reason is not.
I saw one of the greatest memes on quantum shit:
*Two legos talking template*
"What is spin, exactly?"
"It's like when a ball spins but it is not a ball...and it doesn't spin"
Scientists are really good at science...but DAMN, do they suck at naming things.
@@ultimategamer2669 lol like when they name big telescopes.....
@@ultimategamer2669 True, also humans in general seem to be quite crap at naming things. The greatest marketing minds at microsoft named their consoles Xbox, Xbox 360, Xbox One, Xbox One Series X
@@Doombacon LOL. You can say that again. Pretty nonsensical names.
Nothing against the consoles though.
@@ultimategamer2669 Well it behaves exactly as if it were spinning, it just doesn't. The name makes enough sense. You could call it "intrinsic angular momentum" every time but it's a bit long - easier to just call it spin
I am 63 and struggle even with atomic physics. What a wonderful world! I studied physics at school in 1970 and gave it up. Where have I been all these years?
You explain everything so clearly that even an interior designer like me can keep up with the video until the end. Thank you so much for this great work.
Less than halfway through the video and it's already one of the best-explained quantum physics videos I've ever seen.
Agreed
Is just a bunch of lies.
@@visancosmin8991 lolol keep walking
@@abgast Nope. Physical world doesn't exist. "Physical world" is just an idea in consciousness. Consciousness is all there is.
@@visancosmin8991 the physical world is just an idea in whose consciousness? Just yours?
glad to see the long form videos are back, this one was epic. The way I like to think about spin 1/2 is to go around a moebius strip, where you kinda have to go around twice before you get back to the start
Also shout out to Chien Shiung Wu for her discovery about weak force parity breaking!
Hey thanks Mel. Yeah I like the moebius strip analogy, that's cool!

I am a beginner in the field of particle physics however a most interested one. I am really taken by your way to explain the issues related, their presentation and complexity and behaviour etc because you are doing this slowly but astute sharp to the point , with very good pictures and illustrations. I shall be back. A very big thank you for all the great work you are doing to produce your videos
I'm a beginner to physics, and being quite young it's been pretty difficult to follow through and remember everything mentioned. New concepts like spin, quarks, several things in the first few minutes. Definitely worth the rewatch, I'll watch this again when I'm in the right state of mind 👍
Same here😅.
Take a closer look at the letters of the alphabet, they are also the letters of the universe, which are capable of expressing themselves in a way that is unknown to most people. w=wave, describes the shape, (w)atts, (a)mps, (v)oltage, (e)nergy......etc. you can get much deeper into this

Hey, thanks for including the bit about the neutron lifetime question. I have worked on the UCNtau experiment and its nice to see this parameter mentioned as an important question. For those curious, the lifetime is believed to be around 880 sec, but the statistics are still underperforming, and of course this result deviates from the older bottle/beam experiments by such a degree that there is not yet a consensus.
Hey that's cool you worked on this. It is a very interesting area, especially as it seems to be so difficult to pin down!
This might sound like a stupid question, but why aren't nuclei all falling apart if neutrons break down after a matter of minutes?
@@DoctorPlacebothey interact with the proton through the strong nuclear force and one of the quarks gets replaced (as far as I know)
Your illustrations are amazing. This video is going to help a LOT of people conceptualize the fundamentals of particle physics.
You must have put a lot of work into this. Nicely done.
Thanks Kris!
Hello kris
I have am so excited to talk to you kris
The SM Is Total BS.
Proton particle and electron particle are impossible to
exist. The smallest particle is hydrogen atom.
So easy to prove, if all the stars are single protons, all the planets are
single electrons, what will happen?
According to proven physics laws, all the single charged particles will
become one big chunk of mass and there would be no stars. Correct?
What is the shape of an atom? Is atom hard or soft? Does atom has solid
indestructible surface? If carbon atoms are not harder than diamond, how
diamond is made?
Clear as daylight?
Atom is structured as a solid indestructible ball that has opposite
charges near equally distributed on the surface.
Two atoms/masses at any distance, their charges repel and attract each
other, the net force is the source of gravity.
Atoms must have moving parts to carry energy.
All energy in atom is electric energy.
If we don't know exactly how atoms are formed, how to know how everything works correctly? Everything is made from atoms. Yes, we have theories, based on what foundation? Solid or not?
@@domainofscience Thanks Kris? Please tell Kris your video completely ignored the fact that light waves, a property we know light does have..can also explain your imaginary particles! ruclips.net/video/XzxJ65hX_dU/видео.html
I wish I had seen this years ago! Trying to visualize particle physics in my head has always been my stumbling block and this video just made it a whole lot easier.
I have watched this video a few times now in order to prepare for a presentation that I have to do for school. I've seen countless other videos on the topic but none of those compares to the quality and clarity of this video. Thank you so much for making this, this video is amazing!
I was just thinking about your 'map of' videos yesterday and then poof one appears like a particle in quantum foam
Haha my quantum telepathy crystals are working!
Are you aware he includes string theory on his map of quantum physics?
String theory must be hurled into the abyss. IT'S WRONG!
@@ScienceCommunicator2001 Maybe
Same ! Was thinking about the map of mathematics video just yesterday and boom ! New map video
The best explanation I have ever seen about the standard model. Congratulations!
Is just a bunch of lies. There are no particles. There is only consciousness.
I have gotten this poster in my room for a while, but every now and then, I like to watch the video again. I feel there is always a new bit I learn by watching this again. Thank you Dominic
I'm usually read-only on youtube, but just had to say thanks for making this. This is the first video of yours that I've seen, I've only gotten 1/3 the way through it, and you've already earned my subscription. This is an outstanding explanation of very complex and fascinating topics.
In India about 60 percent of current youth is studying with science as their main stream but I find they are drained out of curiosity,such terms make me feel excited and wonder why my peers don't.Sir,please carry on making such amazing informative videos that are enlightening me and the world.I know in my ,life whatever may happen I will never loose this curiosity to learn our world,I hope your efforts may lead others to do the same.
A hearty thank you from India

Excellent video. I've been trying to piece together an understanding of particle physics from various other sources for months, but each source would only cover ever specific slices of what you covered here, and I was just finding them randomly here and there, so I wasn't ever sure if I'd gotten it all, and so it was hard to get a good lay of the land. But this was exactly what I was looking for. Thanks for making it!
I think this is one of the best videos explaining particle physics, along with arvin ash's video. I also love that you doing longer videos now.

This channel is quickly becoming one of my favorites for educational science content. Thank you for what you do!
May i recommend more then??
Just binging on Standard Model videos at the moment, watched more than a dozen. This one really works the best for me, just the right level and beautiful graphics. Many thanks.
Thank you for making these videos! I genuinely feel smarter after watching this. I really feel like I understand the Standard Model much better than before!
Not the most scientific question, but is there any reason we haven’t all just agreed to call the τ particle the “Tauon”?
It sounds so much nicer (in my humble opinion) and would fit the pattern set by Electrons and Muons. The only thing I could think of is that the name Tauon might be taken already but then I’d be surprised never to have heard of it. If anybody could shed some light on the potential reason that’d be greatly appreciated!
P.s. Great video as always, I’d never heard colour (do you have to spell it as ‘color’ for particles?) explained this clearly, and the alternative analogy is very good at explaining why things like Tetraquarks can exist!
I am a simple man. I see the anti-color charges represented as cyan-magenta-yellow, the complementary colors of red-green-blue, and I immediately click like.
@REMF Complementary colors are ones precisely opposite on a color wheel. If you mix them with the color in question (as pigments) you get black.
Thank you so much for this video. For years I've been struggling to understand particle physics to no avail, looking though so many different resources. I'm amazed at how I've learned in a single 1/2h video.
MAN'S SO HUMBLE IN THE END RAMBLE, BEAUTIFUL VIDEO EASY-TO-FOLLOW (WITH ALOTTT OF REWINDING BUT STILL)
This is a great video that goes beyond the bare basics, giving an actual introduction to the standard model. That being said, I actually learned a lot here.
I've been trying to put this complete list together (what are ALL the fundamental particles), and there's always "one more" property. Thank you very much for doing the hard work of completing the map!
24:00 Interestingly enough, at high enough optical intensities (beyond those attainable by current lasers) it is possible for photons to interact with one another. This study of photon-photon interactions is known as nonlinear optics. For example, two photons can combine to create a photon with twice as much energy. However, due to these high intensities not being common in daily life, this isn't frequently observed outside of laboratories.
2 photons can combine into one when shone through some crystal structure
I remember some youtube video about that
@@NoNameAtAll2They dont combine
@@NoNameAtAll2Its a sonic boom that happens when a particle moves faster than a photon of light
That coresponds with mixing of radio signals in a superheterodyne radio receiver. There you mix 2 frequencies in a non linear circuit but you get actually 2 new frequencies out. You get A + B and A - B. Is that the same with photons?
@@leonhardtkristensen4093 it's exactly the same concept with photons. Those two interactions would be "sum-frequency generation" and "difference-frequency generation" respectively. You can also get "second-harmonic generation" where you get 2A and 2B.
I mostly work with infrared light so it's interesting to see an application like that with radio frequencies instead!
Best ever about particles & interactions. Logic, simple, nice, honest. Thanks a lot!
Great video. The quality is just amazing!!
After YEARS of hearing of the standard model I FINALLY understand what it is and why physicists are so sure that there must be a unified theory of everything - THANK YOU.

Great video! I love computer science and the process of digitizing things and the potential for quantum computers.
I literally spent the past two days, usually about once a month I dive into this, but I actually stumbled upon 3 great videos including yours today. The first one that I hope helped me understand wave functions and symmetry is one that had visualizations of waves along the X|Y axis in regards to the frequency, amplitude, momentum, and the electromagnetic dips into imaginary space.
I’m a musician, so once I could visualize a standing wave with the the destructive nodes and constructive anti nodes. It’s such a great help when you can take some sine waves and change the frequency over time so that there’s the phase interference you can actually hear disappear when they hit their respective peak and dip upon the Real and Imaginary space.
It made a lot more since to think of these to particles stuck in place by the inversion of the wave creates a collapse. I am more on the developer side of things then any physics or quantum mechanics, but it’s much easier for me to visualize the wave pattern summing to show the path rather then going straight to “spin” with the standard 3 axis angle rotation.
I’m probably oversimplifying, but atleast now I can a cyclic path extending out in either direction and looping back in on itself to intersect and create a sort of harmonic feedback loop that spawned all space and time, and these interactions of the fundamental wave creates the quantum particles.
Maybe those black holes are locked in a quantum state with negative black holes(which I guess would be peak stars? Lol) to create these huge gravitational wave functions.
This channel is such a cocktail of gorgeous science
As curious is Particle Physics, the video just gives a very amazing and deep insight into it. Just the simplicity of the explanation and the animations just makes the person gripped to it throughout. Thank you for this amazing video. Much appreciated!!

Today , Arvin ash also explained about the standard model . And after watching these two videos i know my brain will explode .
No problem gravity is here
Yeah, I love both channels, Arvin ash deeply explained the Langragian equation of the Standard model.

Even to someone who has watched hundreds on physics videos by now I found this one to be quite helpful.
Brilliant. The clearest presentation I have ever seen of this stuff
Phenomenal. I LOVE DOS. I think you are a very unique educator on RUclips. The way you lay out the subjects in a discipline is really useful for building "wide-minded" scientists. (Scientists who recognize where they stand in their discipline and how to cross disciplines).
God, I love physics so much! This is basically the only channel that actually comprehensively allows me to understand all this stuff
You should try ScienceClic English. It's amazing.
No you dont understand it. Neither does he. Its bollocks
Wow ! This is an awesome summary. I have to watch it again , and again and again :)
This is excellent! Truly. Such generosity with one's knowledge is absolutely commendable. Thank you for making this resource.
I love this video so much, after spending countless hours watching videos on the subject, this really brings it together and connects it all
I’m having this subject at college right now! Thank you for the video, it helped me a lot to understand it!.
I really don't understand much of what I'm hearing, but this feels so well-presented that I'm gonna keep coming back to it. I'll understand all of it some day. 🥰
My thought as well.
watching this to get my footing before studying for my particle physics final...I won't lie, this laid out the context and motivations for the class better than my professor did!
One of the best videos I have ever watched on some topic of physics.
The way you explained everything with the help of diagrams is kind of amazing.
Thanks, for your's awesome work !!
Great narration like a documentary.
Thanks a lot DoS.
A mobius strip needs 2 full revolutions to get back to a starting position. I see one spinning as an analogy of 1/2 spin.
Edit: I see the same earlier independent comment. So maybe useful.
The Möbius strip is a sham, the acceptance of which may be as silly as stating that the circumference of a circle or loop is infinite or that time exists,
for it consists in no-more than an object with little more than two surfaces having its ends cleverly joined so as to appear to have a single surface
@@JoePortly regardless, it is a mathematical truth. yes, one can argue that the surface of a sphere is infinite and uninterrupted, obviously because this would be a reality for anyone "living" on the surface. contrast this to a cylinder or a cone. the actual construction of such a body is irrelevant, mathematically speaking. if you can't fathom the difference, than you don't really appreciate the necessary abstraction of ideas.
@@JoePortly you can easily create a solid, continuous mobius strip. the fact that its usually made of paper has little relevance to the topography.
Just discovered this channel. It is soo underrated.
What a wonderful world of particle Physics, and explained extremely well! Thank you sir! I wish I had these when I was really in love with Physics!
Can you do a map of all simple groups in abstract algebra? That would be awesome
This was so good! I work in a neutrino physics lab, and this is far and away the best explanation of all of this stuff I've seen minus the jargon
but how do we know right handed neutrinos don't exist and it's not just that we can't detect them because they interact less with matter?
I love how all of these particles have so many properties and interaction based logic behind them, that we're really grasping at straws trying to find unused metaphors and analogies to describe them. There's just something very human about it.
ive been taking notes of this video for four days and i finally finished it. VERY helpful !
Fascinating to watch your videos as always! May I ask which software/tools you use to make 'Map of' videos?
I've been rewatching this for a while now😂. It's actually pretty interesting but I'm finding it hard to understand the leptons( especially the lepton numbers) symmetries and the neutrinos. But except all that I understood the rest. You really explained very well and you made it very comprehensive and detailed. Thanks very much😊😊❤️.
If a four-year-old asks me that question, I would ask that kid to wait till the time has come where he/she can understand my explanation.
Excellently presented. Thank you.
I don't 'understand' this but I've spent a good part of my life following it at my own level!
Amazing! Thank you so much for this detailed explanation. I no longer feel completely lost in my particle physics class. Keep 'em coming!
Amazing content! Best presentation/lecture I've seen in my entire 4 years of academics...
Wow. Just WOW ! So much I didn't know about the standard model despite it being mentioned so often. So much that is NEVER told, not even alluded to. And still you presented this in a casual way that was very understandable !!!
Extremely superb and comprehensive explanation that I've been trying to get for many weeks
I just wanna thank you for your efforts with these maps it opened my mind to a lot of things . Can you do a map about industrial engineering? Thank you
"Don’t worry about subscribing unless you really want to"
I really want to.
For some reason this was saved in my physics playlist. I’m not complaining it’s good to have some laugh before I cry for exams
100 years of physics boiled down to a digestible, byte sized video. Thank you.
I've been waiting for a video like this for ages. To be able to explain a complicated theory like this, so comprehensively, in about half an hour is great. What would be a great follow-up would be how these various phenomena were derived. For example, starting with Rutherford's simple experiment of bombarding gold nuclei with alpha particles - to determine the constituents of nuclei or the Stern-Gerlach experiment to determine 1/2 integer spin. So, for example, what experiment(s) determined the Color Charge of Quarks? Looking forward to how the Map of Particle Physics was determined.
Man. This is amazing! I have no idea what kinds of degree you have, but in my world you are a grand Physics Professor :) thanks for spreading knowledge in such a well made way.
One of the best (slightly uncertain) videos on the subject made. I watch them all.
Last week I had a test on this subject and I looked for a explanation on this channel. One week later, a whole explanation. One week toolate😪
Best day of my life first arvin ash upload an amazing video and now this DMS the map of particle physics
What a lovely day
true! what a coincidence
Adding my voice to the choir. Truly excellent video. Filling in the gaps of my knowledge. Thank you so much.
The best explanation of what is spin I've ever seen. Congratulations for that!
I just discovered a new particle. Its called "confusi-ion" and there is currently an overload of them inside my brain
No doubt, it's hard to understand when the people explaining it are making up words and using bad analogies.
Check out this new model of the periodic table the Thunderbolts Project put up a few days ago. ruclips.net/video/EDxmp04h3Bo/видео.html
Makes way more sense imo. And if you like it subscribe to the channel, they are associated with and following closely a group that have built a working sun, basically.
They call it The Safire Project.
Wha what is time? I died right there 😂 great video!
Brilliant channel, and fantastic delivery by the way. You and Sabine Hossenfelder are top of the list for this stuff.
absolutely love this vid and your posters, thank you, dude!
According to all we know, Dominic breaks the conservation laws, because his charmness is constantly increasing, the longer you look into his cuddly eyes... :p
* doesn't include neutrinos in the higgs field interaction visual *
*_"That was a bold move Mr. Freeman"_*
clearest explanation of spin yet - thanks for this video!
You just gave us all a free, amazing , enough detailed course on Quantum Physics. You changed how I saw the world. It is not included in textbooks and a lot of other books.
Edit: I feel like, I wasted 6 months of life.
Hi! Even though our school haven't discussed about physics yet, I already find this type of things interesting. Thanks DoS, I'm learning a lot!
As a dumbass who has an interest in everything, I'm really glad a video like this helped me conceptualize and understand such a terribly complicated topic. Thank you so much!
You just got your dopamine fix without actually putting in the work.
@@visancosmin8991 very true, it's a waste of time really if it comes at the expense of your own achievements and growth, watching videos of what other people have discovered all day along and regurgitating it in family gatherings
Hey Mridul Same here 😀🥀
Your explanations and illustrations are amazing! Keep it up 👍
This is outstanding!!
To see and see and see again!
The answer to "why do things exist?" Is that, If they didn't, we wouldn't be here to ask that question. Things must exist, but they didn't always, and they wont forever.
That is not an answer to the question. It only indirectly proves that things exist.
@@pasijutaulietuviuesas9174 "things must exist"
@@AlexFoster2291 That still doesn't answer the question. It only explains that things can't not exist. That they have to exist. It doesn't not explain why. Why is the sun shining? Because it has to shine. Not a very useful answer, is it?
My guts stick with string theory on why everything exists, might be wrong, but I like how elegant and beautiful it is.
omg!!! how is it I have only just found this channel??
if the rest of the videos are as good as this then I will definitely watch them all, such as "The map of quantum physics", which is now in my recommendation bar.
Thank you, these explanations were very valuable to me! The excellent graphics made it all better. I have been interested in physics for a long time, but often struggle with finding education material that is on a good level to start at (either it's too simplistic, too complicated or just poorly explained). This was perfect.
Well confused but very happy
Dont give up.and try more than thousand times
16:23 I never understood why you would mark the antiparticle with a bar while ALSO showing that they move backwards in time on the Feynman diagram. To me it just looks like an antineutrino going backwards in time, which would just make it a regular neutrino...
The arrows are necessary as they describe particle flow. Whether it is a particle or anti-particle depends on which way time flows in the feynman diagram, the arrow with time is a particle and the arrow against time is an antiparticle
@@hotlinkster123 Yes, but then they also mark it with a bar on top of the particle which is redundant at best.
