The Standard Model - with Harry Cliff 

This guy is an awesome speaker. Keeps it in understandable terminology. Love the royal institution lectures.

This is by far the most clear, concise and eloquent description of a very confusing, complex & counter intuitive model

That woman, sleeping in the background, cracks me up every time i see her :D

Wow This Video is SUPERB!!!!! There are SO MANY pearls of WISDOM that get dropped in this Video it’s AMAZING!!!! 10/10 STARS MATE!!!!! He really knows his stuff!!!!!

this is the single most interesting and informative video I've ever seen

Note to self: When you feel sleepy, never sit in the front row.

If the muon decays into a electron and neutrinos, how is it fundamental. Just curious, I want to go into particle and quantum physics so knowing these things are helpful.

The explanation is very clear and I can even understand it! I love your speech. Learned a lot

I'm studying this at school and even my teacher couldn't explain it properly eh.. I haven't find any material in my language so this video really helped me

This gas been the clearest to understand to someone like me. Thank you. Will search for the continuation of the talk!

This is very helpful. I am reading “Galileo’s Finger” by Peter Atkins where he talked about fundamental particles and this vid really helped me to understand the condept

7:15 me (in the background) when the most important part of lecture comes which would've built my basic understanding of the topic

he missed a couple things like: every fermions has anti-fermions, there are positive and negative W gauge bosons and the fact that quantum electrodynamics also includes positrons that react as the electromagnetic force with electrons that exchange photons.

O wish Mr Faraday could see this lecture

A very lucid lecture. Excellent!

The PARTICLE TRAIN! Previously I suggested that eternal photons made electron positron pairs, (as well as all standard model particles). Here's how. Start with a PARTICLE TRAIN, each time you add an electron or positron car to the train, you get a new particle. The only rule is the cars have to alternate from electron to positron. Think of a wave with trough always alternating with crest. Photons as electron positron pairs could make the main parts of an atom in the brief time after the Big Bang under those extreme and never repeated conditions. Charges are the cars on our particle train. Positive positron (+), Negative electron (-). Positron (+) Electron (-) Photon (+) (-) Proton (+) (-) (+) Anti Proton (-) (+) (-) Neutron (+) (-) (+) (-) Anti Neutron (-) (+) (-)(+) . The PROTONS and NEUTRONS are made from ELECTRONS and POSITRONS! When this production of particles was over, most anti particles with charge; positrons, and anti protons, didn't exist on their own. They were LOCKED INTO PROTONS OR NEUTRONS. That way conservation of charge was maintained. That also explains the MISSING ANTI MATTER PROBLEM! This from Wikipedia article Matter Creation: It is possible to create all fundamental particles in the standard model, including quarks, leptons and bosons using photons of varying energies above some minimum threshold, whether directly (by pair production), or by decay of the intermediate particle (such as a W− boson decaying to form an electron and an electron-antineutrino).

An excellent explanation.

in 12 minutes you explained 2 weeks of lecture material at my university for free... Really makes you wonder why university is still a thing. I could argue that the youth pay for the countries research like child labour to make clothes. Hopefully education changes with the times...

The original video was fine, no need to cut it out in pieces, we can hold our attention for an hour...

Classy presentation quality...

I needed a refresher for standard model after the announcement from Fermilab

Well done!

Cool video! So does the Higgs field not interact at all with photons and other massless particles? How is that explained?

the women near the exit have learnt alot that day :D

Have a look at Ultra Unification: Quantum Fields Beyond the Standard Model (Unified model beyond grand unification) PhysRevD.103.105024

Good talk

No it's not particles bumping off fields it's particles moving through fields that consists of more dimensions that we can't conceive and so on.

So my TShirt that I got to support The R.I. came in the mail today, courtesy of the Royal Postal Service.(keeping the packet because it's my first packet from the U.K.) but any how....I was so pleased with it! It's the short that has the print out of "The Standard Model" when I put it on to show my wife, knowing she'd jus roll her eyes an say, " Oh, got yourself another 'nerd' shirt."...she didn't say anything. She actually stared at it for a minute. Just a blank stare. Then she looked up, into my eyes, an said, "I don't like it." ...I asked why, it's the standard model of everything the universe is made of, all the fundamental particles....she said...."somethings missing......I don't know what, but it's wrong....." So....how right is she? What is missing from the standard model that we are still looking for? Cause I can't wear my new t-shirt thinking it's incomplete, let alone in front of her, without being judged as an incomplete fool....please help R.I. !

Clear info!

A muon decays into "an electron and some neutrino's", but a muon is about 200 times the mass of an electron. Then either the neutrino's are very heavy (which I thought they absolutely weren't), or there must be an awful lot of light neutrino's being produced (which contradicts the "some"), or quite some energy is being released (E=mc2 where m would be 199*the mass of an electron). Right?

There are 3 particles you are all made of, that's it! And they explain everything! ... ok, except of gravity. ... and then there are Myons ... ... and then there are 3 generations of all of them ... ... and then there are force particles ... ... and then there are ...

You've heard of Harry Hill now get ready for Harry Cliff.

Harry Cliff is gorgeous 😍 Love the way he explains.

Really good

Great

great overview but too, too short.

How to Get full lecture ?

are quarks really indivisible ? or, some century later, somebody will say they are made of further more physical things ?

Wow I finally understand

The more learn, the more we yearn.

Should have told the names of the all the blocks.. like top,charm,strange, bottom, tau neutrino etc.. It would have been more beneficial to the students.

Question, please: What is the smallest, most elemental thing in the universe?

I wish he was my physics teacher😎

*_[_**_10:32_**_] 'hokum'-electrons have mass because they are energy convolved on itself, and, the momentum equation shows force imparts energy as a statistic-integration of wave-shifting (there's no Higgs impartation in that-unless rather, the Higgs, assigns, the mass-values, to particles... or the vacuum speed of light to photons... or else converts potential to kinetic)..._*

So the 4th of July is Independence Day and Higgs day?

I wonder to which degree Mendeleev felt like a Victorian.

How do we know there aren't extra columns? Like a 4th generation?

If the 2nd generation particles can be broken down to electrons and neutrinos, are they fundamental particles?

Here it is gravity doesn't exist it's neutrinos counteracting the electromagnetism

So just by being, I'm a great disturbance in the field?

I love how the numbers on the standard model aren't explained at all....

5:13 she's sleeping...

👍👍👍👍👍👍

Even Albert Einstein was sceptic about the quantum theory... But its convincing.. I mean you may be genius but there are a lot more to know... To understand

The correct pronunciation of 'quark' is actually ... [imagine the sound of a duck here] ... Because Murray Gell-Mann said so.

I would say that the particles of The Standard Model are about a Gaggoogol times smaller in diameter than The Planck Length. A field is just a probabilistic description of a particle. There is still a particle there. I never though of these particles as hard spheres but rather fuzzy, sphere-like things.

I think Harry Cliff is in hurry to end the lecture...

Hocus pocus I take pills to focus

i allready saw this, why are you making short video snippets of old videos i dont want to watch? :(

That woman in the front is in the wrong lecture room.

Soo if every particle is jst an excitation of fields , and these particles make matter does than mean nothing is real 😄😄😄.

Uploaded on the same day as the Boston Dynamics video of AI using a physical body to parkour.

It sounds like he's talking on a grade school level.

I am eager for someone to debunk this theory as I don't believe myself worthy to have such insights: I don't think the force we term "gravity" is a separate entity to either relativity or quantum mechanics, I think it is a result of the contraction effect that mass has on it, mass given to up and down quarks by the higgs field. The "matter", "forces" and "energy" we are created from and experience are merely errors and fluctuations in the unfathomable scale (therefore infinitely likely probability) of the fields that in turn cause them to "cross" and "intersect" (I'm imagining the images of something similar to the plasma filled magnetic loops that occur and cross on the surface of our sun), resulting in a phenomena we call "matter". My hypothesis on the reason we don't immediately fly back apart due to natural correction of these errors in the field, is because we exist in an elongated perception of the time phenomena of the space-time fields. I also think that neutrinos are the ultimate form of high-entropy for the universe to create a uniform low-energy state, all quarks eventually ceasing to be created by the soothing effect neutrinos have on all "fields". I believe a conclusion could also be drawn that black holes are, in fact, areas where all fields premating the "universe" are synchronised and uniform, therefore unknown and incomprehensible. Maybe...….

Consider the following: The heart in a human supposedly takes the place of one of the lobes of one of the lungs. Now, if we can come up with a device, (via natural DNA or man-made technology), that could convert CO2 into C and O2, and put it in place of one of the lobes of the other lung, or find somewhere else in the body to put it and leave the other lung alone, and maybe the C gets routed to the stomach and the O2 back into the bloodstream, would it be possible to create an entity that could never be suffocated or be drowned? Sure, quarks, electrons and energy would still be needed to the entity to grow and to replace those items that left the body, but would it be possible to do? And then consider also, if astronauts had this done, they would be better able to survive in outer space and on planets and moons with little or no oxygen. Of which, if species do not get off of this Earth and out of this solar system, we are all going to die one day from something and go extinct. Life itself would all be ultimately meaningless in the grand scheme of things. So, why not at least try it? Think also of the Earthly applications for the military, fire fighters, etc. A hybrid next generation human.

Nice lecture but you sir completely failed to explain what a field is. "A field is like a magnetic field of a gravitational field"... Really?

Mendeleev, Russian scientist, you prof. Hairy He was the one who made the predictions and the incomplete table

dont speedtalk.

Does particle physics explain where all these forces come from? What makes all these forces different? Can someone explain where spin comes from? Particle physics is a joke... It doesn't explain anything.

so mass is not real anymore

One of the worst video productions for an education presentation. You get half a second to see the slides then the camera focuses on the speaker for who knows why. I've haven't seen these atomic models before. Show the face in the beginning and end, and leave the rest to the slides.

Here is a copy and paste of my latest TOE idea along with a test for what I believe 'gravity' truly is: Revised TOE: 3/25/2017a. My Current TOE: THE SETUP: 1. Modern science currently recognizes four forces of nature: The strong nuclear force, the weak nuclear force, gravity, and electromagnetism. 2. In school we are taught that with magnetism, opposite polarities attract and like polarities repel. But inside the arc of a large horseshoe magnet it's the other way around, like polarities attract and opposite polarities repel. (I have proved this to myself with magnets and anybody with a large horseshoe magnet and two smaller bar magnets can easily prove this to yourself too. It occurs at the outer end of the inner arc of the horseshoe magnet.). 3. Charged particles have an associated magnetic field with them. 4. Protons and electrons are charged particles and have their associated magnetic fields with them. 5. Photons also have both an electric and a magnetic component to them. FOUR FORCES OF NATURE DOWN INTO TWO: 6. When an electron is in close proximity to the nucleus, it would basically generate a 360 degree spherical magnetic field. 7. Like charged protons would stick together inside of this magnetic field, while simultaneously repelling opposite charged electrons inside this magnetic field, while simultaneously attracting the opposite charged electrons across the inner portion of the electron's moving magnetic field. 8. There are probably no such thing as "gluons" in actual reality. 9. The strong nuclear force and the weak nuclear force are probably derivatives of the electro-magnetic field interactions between electrons and protons. 10. The nucleus is probably an electro-magnetic field boundary. 11. Quarks also supposedly have a charge to them and then would also most likely have electro-magnetic fields associated with them, possibly a different arrangement for each of the six different type of quarks. 12. The interactions between the quarks EM forces are how and why protons and neutrons formulate as well as how and why protons and neutrons stay inside of the nucleus and do not just pass through as neutrinos do. THE GEM FORCE INTERACTIONS AND QUANTA: 13. Personally, I currently believe that the directional force in photons is "gravity". It's the force that makes the sine wave of EM energy go from a wide (maximum extension) to a point (minimum extension) of a moving photon and acts 90 degrees to the EM forces which act 90 degrees to each other. When the EM gets to maximum extension, "gravity" flips and EM goes to minimum, then "gravity" flips and goes back to maximum, etc, etc. A stationary photon would pulse from it's maximum extension to a point possibly even too small to detect, then back to maximum, etc, etc. 14. I also believe that a pulsating, swirling singularity (which is basically a pulsating, swirling 'gem' photon) is the energy unit in this universe. 15. When these pulsating, swirling energy units interact with other energy units, they tangle together and can interlock at times. Various shapes (strings, spheres, whatever) might be formed, which then create sub-atomic material, atoms, molecules, and everything in existence in this universe. 16. When the energy units unite and interlock together they would tend to stabilize and vibrate. 17. I believe there is probably a Photonic Theory Of The Atomic Structure. 18. Everything is basically "light" (photons) in a universe entirely filled with "light" (photons). THE MAGNETIC FORCE SPECIFICALLY: 19. When the electron with it's associated magnetic field goes around the proton with it's associated magnetic field, internal and external energy oscillations are set up. 20. When more than one atom is involved, and these energy frequencies align, they add together, specifically the magnetic field frequency. 21. I currently believe that this is where a line of flux originates from, aligned magnetic field frequencies. NOTES: 22. The Earth can be looked at as being a massive singular interacting photon with it's magnetic field, electrical surface field, and gravity, all three photonic forces all being 90 degrees from each other. 23. The flat spiral galaxy can be looked at as being a massive singular interacting photon with it's magnetic fields on each side of the plane of matter, the electrical field along the plane of matter, and gravity being directed towards the galactic center's black hole where the gravitational forces would meet, all three photonic forces all being 90 degrees from each other. 24. As below in the singularity, as above in the galaxy and probably universe as well. 25. I believe there are only two forces of nature, Gravity and EM, (GEM). Due to the stability of the GEM with the energy unit, this is also why the forces of nature haven't evolved by now. Of which with the current theory of understanding, how come the forces of nature haven't evolved by now since the original conditions acting upon the singularity aren't acting upon them like they originally were, billions of years have supposedly elapsed, in a universe that continues to expand and cool, with energy that could not be created nor destroyed would be getting less and less dense? My theory would seem to make more sense if in fact it is really true. I really wonder if it is in fact really true. 26. And the universe would be expanding due to these pulsating and interacting energy units and would also allow galaxies to collide, of which, how could galaxies ever collide if they are all speeding away from each other like is currently taught? DISCLAIMER: 27. As I as well as all of humanity truly do not know what we do not know, the above certainly could be wrong. It would have to be proved or disproved to know for more certainty. __________________________________________________________ Here is the test for the 'gravity' portion of my TOE idea. I do not have the necessary resources to do the test but maybe you or someone else reading this does, will do the test, then tell the world what is found out either way. a. Imagine a 12 hour clock. b. Put a magnetic field across from the 3 to 9 o'clock positions. c. Put an electric field across from the 6 to 12 o'clock positions. (The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.) d. Shoot a high powered laser through the center of the clock at 90 degrees to the em fields. e. Do this with the em fields on and off. (The em fields could be varied in size, strength, density and depth. The intent would be to energy frequency match the laser and em fields for optimal results.) f. Look for any gravitational / anti-gravitational effects. (Including the utilization of ferro cells so as to be able to actually see the energy field movements.) (An alternative to the above would be to shoot 3 high powered lasers, or a single high powered laser split into 3 beams, each adjustable to achieve the above set up, all focused upon a single point in space.) 'If' effects are noted, 'then' further research could be done. 'If' effects are not noted, 'then' my latest TOE idea is wrong. But still, we would know what 'gravity' was not, which is still something in the scientific world. Science still wins either way and moves forward.

Am I the only 11 year old here

how could you weigh something and say that it’s heavy when it would be weightless in space? 🤔🤷‍♂️

Its striking how similar science and religion are Good evil Dark light Heaven hell Matter antimatter Ect

2nd !!!

Very smart people, yet still can’t manage their own audio. This is ear assault.

Could you have provided more evidence please. Your insights are indistinguishable from parroting your favourite deep thinkers.

Listen you all to Current Value's uncertainty principal and learn you can be dump ;)

why do the background people look like cgi double.....

Imagine that all us had the capability of accessing that cosmic field with our own particles and thereby manipulate space and time. 🤔😎

I did not know that Sebbastian Vettel had a phisyscist brother

Hey you copied tedshow
