When you start watching Quantum Chromodynamics videos after midnight, you know you've ended up in the "weird" part of KZread again. This quantum sh*t could be mind bending while having a joint.... which by the way I never do, nonetheless it's fascinating to imagine it. ;D

One of the most masterful physics professors on planet Earth!! You truly set the bar for all other professors!!!

I propose to have a playlist strictly dedicated to Dr. Don on this channel.

after watching this, I watched like 6 hours of worth of lectures that talk some/were about qcd. the Fermilab channel is definitely up there with all of the Brady Haran channels in my book. Can I just have all of Dr Don's shirts?

Up and down, from top to bottom, I think you're charming and strange.

Really enjoying these videos. Fermilab has done a fantastic job with them. Thank you!

One of the best videos about physics I have found on KZread. Thanks and congratulations.

You do an outstanding job of bringing complex physics to the lay person and I love watching your channel.

This video is really awesome! Keep posting more in depth stuff like this.

always impressive. thank you, fermilab. 감사합니다.

Feels bad people have enough time to waste upon watching worthless videos and ignoring these amazing videos of reality of our world. Great work sir by the way. I'm so pleased to watch ur videos 😊😊😊

great video as always!

First video of yours I've watched. Very impressed and can't wait to watch more! Earned yourself a sub good sir

Whoo hoo, you are finally getting into QCD. I hope you can go more into depth with QCD at some point. In order to explain some of the points regarding asymptotic freedom, and how weird it is (you touched on it in this vid, but I would like it if you went more in depth, in some future video) creating mesons with the excess gluon energy so it is absolutely impossible to ever see a single quark. Likewise, that the Strong Nucelar Force is just a tiny bit of left over force leaking out of the quark-gluon interaction. It really blew my mind, and continues to do so, knowing we only exist because the gluon field is so strong that tiny bits that leak out of it are what holds nucleons together. That the tiny bit of excess energy leaking out of the system is so strong, that it remains the strongest force in the universe, even though it is basically just race amounts getting out due to confinement.

Out if this world 🌎!!!!May be best vid on topic and great delivery ! Thank you,

Thanks Dr. Don for explaining the QED … u can make physics a piece of cake to any layman…

Thank you for clear explanation. By the way, I suppose that the term "Quantum Chromo-Dynamics" is like that of 3 linguistic fun. Namely, the 'Quantum' derives from Latin, 'Chromo' from Greek and 'Dynamics' is English in itself. Eventually the usage of these 3 sorts of languages is the same idea of 3 sorts of coloristic tiny particles in the mother bowl, I perceive. Very ingenious and reasonable usage. Yes, that's the same term as 3 characteristic languages vs particles. So be happy !

I have limited formal sceince education, I enjoy watching these videos, one has to marvel at the sheer brilliance of the human mind .

The best lecturer that ever was!

Thanks a lot. 👍 I do appreciate it! 3:06 In any event, unlike electric charge, which comes in two varieties: plus and minus, the strong charge comes in three varieties, named red, blue and green, anain, nothing to do with regular color. The particles that the colored quarks exchange are not photons, but rather particles called gluons. The photon is the particle of electromagnetic force and the gluon is the particle of the strong force. And, in analogy with QED or quantum ELECTROdynamics, we call this theory QCD for quantum CHROMOdynamics. Get it? Chromo? Color? Alright, sometimes I'm a little embarrassed by my tribe. For those of you who are fans of Feynman diagrams, we draw an exchanged photon as a wavy line, while a gluon is a corkscrew. And, just like all Feynman diagram, the Feynman diagram of two quarks exchanging a gluon orresponds to an equation that a sufficiently diligent stuend can solve. ... So how is QCD different from QED? Both involved exchanging force carrying particles between other particles carrying charge. The photon is massless. The gluon is massless. The photon has no electric charge. The gluon has no- oh wait a minute ... there's a difference. Gluons carry the strong charge. They have color. And that little different has a huge consequence. 4:28 5:42 But here's the tricy thing. When we break it, the energy that was stored in the string converts into matter and antimatter, specifically quarks and antiquarks. This process can go on for a while with more stretching and breaking and creating quarks and antiquark pairs. In the end, the particles all pairs up and what we get is a bunck of particles all travelling more or less in the same direction as the quark that got knocked out of the nucleon. Physicists call this blast of particles a jet. 6:09 And we see jets all the time. Here is a picture of a real even collision in the CMS detector, 6:12 one of the big LHC experiments. See those sprays of particles? Those are jets. So those are the big ideas of quantum chromodynamics. The strong force has a different charge and force carrying particle than quantum electrodynamics, but, in some respects, theay aren't so incredibly different. The big difference is the fact that the force carrying particles is itself charged with, as we have seen, dramatic consequences. The subatomic realm is really a pretty crazy place. 👍

Fantastic video. Thank you.

Excellent explanation ☺️

i'd like to hear more about the "string of colour charge" concept. i've also heard of them being referred to as 'flux tubes' & being explained as being like a column of true vacuum between the quarks. i've also heard of them being called 'gluons' & being explained as a particle interaction. i'd like to hear FermiLab's take on this, or someone's.

Love this, very straightforward and Dr.Don's jokes are really quircky.

i love this i have been learning quantum physics and quantum mechanics along with quantum chromodynamics

brilliant explanation. bravo

The quarks that build up things like protons are held together by a small exchange of mass. They swap "charges" and that interaction keeps them close together. Nothing unimaginable going on like really fast moving particles that somehow magically generate a force...

Very good video! Thank

Hey, I have few questions on QCD. Question 1 of 4000: Is there reasons, why quarks have such high velocity/energy, and gluons possess such huge energy; and why that energy won’t emerge as weaker virtual particles or bozons before reaching gluon threshold? I.e. why this energy is reserved to quark/gluons only? Thanks for these vids!

Excellent.... thanks 🙏

Is the sphere of a nucleon something like the 'soup' in a nucleus of cellbiology or is the sphere just a representation of of the length the different quarks can travel from each other?

Excellent.... thanks.

Dr Lincolm - in your presentation , quarks are depicted as flying randomly about with the sphere of a nucleon , making sudden changes in path via some acute angles and yet bouncing seemingly elastically of the spherical external wall of the nucleon. Is this correct ? Are nucleons under normal circumstances - outside of the accelerator free to move about in these chaotic patterns and yet instantly constrained and redirected when they hit the “wall” of the nucleons perimeter ? If this is the case than I seems as if the “wall” of the nucleon must itself be made of some solid structure such that it can redirect the quark back into the sphere as If it had impacted the edge of a pool table. Thanks much for the discussion,.

Thank you Sir😍

Really great and enjoyable, may I get book u wrote thanks Regards

Thank you sir

cheers Don

Excellent.

A complete, well designed and stable world exists inside a nucleus. One question - will these properties remain the same at all values of gravity? E.g will these properties change closer to a blackhole or a neutron star?

So is there a physical shell holding the quarks in a nucleon, or is it a force as you described?

Wouldn't it be more correct, if you say electromagnetism has two charges (+ and -), that QCD has *six* charges (red-antired, green-antigreen, blue-antiblue)?

I guess that depends on if there are any remaining symmetries in the topology of k in your gallois representations for further dimensionality, or if you've already arrived at your del0 Z transform right? If it's zero their higher dim duality is fundamentally unitary at Csub0. Otherwise they are further decomposable, I think? Quantum harmonics are hard >.< Especially when you're working with relativistic chromogeometries with fundamentally moduloarithmetic properties.

Nice video

Matter can be explained as energy with points and those points at times have reference. Like a bathroom surrounded by reflecting wall tiles or a room surrounded by mirrors top to bottom.

QCD is the study of strong force interactions which happen via gluons. The quarks and gluons both carry colour charge unlike QED.

Nice video! However I'm a bit confused now. This video makes be believe that the strong force is the force holding the quarks in a proton or neutron together. In your video about the strong force it was introduced as the force holding the protons and neutrons in a nucleus together. Or is it both due to the strong force?

@sumsar01

4 жыл бұрын

It is both. Quarks are held together by gluons, while the nucleus is held together by mesons. But both are due to the strong force.

very nice

Do the protons and neutrons inside a nucleus remain distinct packages, or does it all dissolve into some kind of quark soup?

Thank u don lov u

Are self-interacting force carriers a sufficient per-condition to confinement or is there more to it?

I think color was a pretty good choice for the strong force charge. I can't think of many other analogies where things come in threes. For two things, plus and minus works. We use north and south for magnets (which is an obvious choice considering the Earth's magnetic field). Male / Female, left / right, up / down. But not many things in threes...

@DrDeuteron

it's not just the 3 colors. There are also 3 anti colors in QCD, and we use the complementary colors on the color wheel for those, or not ("anti-blue" is as good as "yellow"). The real kicker is that physical states we see are always colorless, and as such are made from either 3 colored quarks, or 3 anti-colored antiquarks, or 1 colored quark and 1 anti-colored anti quark....which is exactly how we interpret colors to make neutral shades/white....however, for QCD it stems from the representation theory of the Lie group, SU(3). It's a convenient coincidence.

So are these charges detectable through the electromagnetic field? Can these "color" charges directly interact with electric charges?

Do you have a video explaining how the particle collision detectors work? I want to know how you compute the jets.

@sumsar01

4 жыл бұрын

They basically use photoelectrons. But how the detectors work arent really related to computing jets. You would have to compute Feynman diagrams to find the cross section etc. etc. You can probably find out how if you look for compton scattering. That is probably the most basic example.

sir you are great

Does nucleus at end keeps its quark? What happens, if hit are all quarks? Does whole nucleus is moved or stretched? Or strong force tries to keep all of them in its place by breaking and creating multiple nucleuses.

I learned more about the what the LHC does in 3.5 minutes (thanks KZread double speed) than I have in all the hours I’ve spent watching tv or documentaries about the LHC

So when you have two magnets in contact, and there is a force between them, are there photons required to establish the force? There is no energy transmission between the magnets in the static condition. So the electromagnetic force does not need photons for the static case. It only needs photons for the accelerating case. If there are no photons required for a static example, does that imply that objects other than photons can interact with electromagnetic fields?

great videos!! ''...photons, which are completely oblivious to each others existance...'' wait so why do EM waves cancel out eachother if they are out of phase?

@sumsar01

4 жыл бұрын

A classical EM wave is not a photon, but billions of photons. Photons can also turn into an electron and a positron. By doing this it is basically possible for two photons to scatter each other.
