Santa is a smart man.
Omg ahahahahahahaha
Dumbedore in physics
that was literally what I was thinking about
Course he is, he knows what you want one day in the year( the other 364 days, he's in an Amazon warehouse)
These guys are the real wizard of our world.
Question: We all know what snow is made of?
Me: Finally something i know, water!
Answer: Snowflakes
Me: -_-
It is made of ice
You getting comments after 9 years, damnnnn😂😂😂
If you were a kid back then, you might be having kids now😂😂😂
Curiously Interesting. Is this meant to begin to explain energy and frequency 'particles'? ... and into Tesla's world we go? 🎇
Snowflakes, eh. I wonder who came up with that, like really ... who? Serious question.
I already knew what a Higgs boson was, I just wanted to see your awesome beard.
John Ellis described the Higgs very clearly and understandably for me a non scientist, but popular science fan.
Don't sell yourself short...you're the MOST popular science fan! *sorry. I couldn't resist. Cheers.
Andy Trullinger Thank you!
I had no idea Santa was such an intelligent scientist
Great explanation. Thank you very much for all the hard work that you guys have done. Also Thank you for not blowing us up in search of the Higgs particle. Best Regards
How do you know he didn't?
Considering that I've been out of school since most of these guys were working on why Oreos float in milk, but then sink, that was a pretty good explanation of something we think is real, but don't really know for an absolute fact. It sure as shoot saved me from endless hours of reading. So I had to give the guy a thumbs UP.
It was now proven!
that intro scared the shit outta me
All of the comments are like "ERR MEHHH GEERRDD CERN IS PLAYING GOD"........hahahaha
TheBlashMusic welcome to the internet.
maybe someone can correct me if i'm wrong but I just learned about the Higgs Boson in Astronomy class and the professor explained the significance of it as such:
There are four universal forces which everything undergoes -
Strong force, electromagnetism, weak force, and gravity.
All these forces have units, all of which we have directly or indirectly observed. Except for one, the so-called 'graviton' for gravity. It is believed that the Higgs Boson is this 'graviton' which mediates gravity.
From what I understand: There is a permeating field called the Higgs Field. If you interact with the field, you have mass. If you excite the Higgs Field, you can cause a particle to be released, the Higgs Particle, or Higgs Boson. If you drop a tiny ball of sponge onto water, it won't do much because there is a low energy. If you drop a rock into the water (high mass) then a blob of water will come flying out (Higgs Boson) and then quickly deteriorate away back into the water when it lands.
What is snow made of ? Snow flakes
Interesting...
That's hot 😎
reading all the nerd comments, hold on.......... I had to grab my thesaurus. continue on.
exactly, it's CREATING the boson, by decomposing the bigger particles that it smashes, and the super sensitive sensors detect,measure,observe,characterize it. you're spot on
TWELVE YEARS LATER,SOMEONE IN THIS UNIVERSE REPLIED…
Tried reading the Wikipedia article for the Higgs boson, it got confusing and I only got that the boson proved mass. This helped in how masses are through the analogy and helped reinforce the proof. Helpful for getting a basic yet useful understanding of this new scientific discovery.
where do I get that shirt ?
I saw some at CERN gift shop.
understand and memorize the formula, than write it on any shirt
@@melonangie "understand" hahahahahaha
@@melonangie yep , that's how i got my Schrödinger Equation Tshirt and my Maxwell Equation pants back in the early 80s :o)
This is the best explanation on the Higgs boson.
Wow. Thanks. I have been trying to understand the Higgs Boson idea. After quite a bit of surfing, I found this video and you explained it so well that I understand it now. THANK YOU!
If you're wondering the formula on his shirt is part of the mathematics related to the Higgs Boson. Like he says in the video, they're the basic equations of the standard models. Really good explanation too, I was confused before Santa cleared it up with his analogies.
It confirms our current understanding of the standard model of particle physics. We also might be able to engineer things to use it's characteristics to our advantage like we did with the electron.
I am concerned with the fact that scientific youtube video's always turn out into religious discussions. I am a firm believer in the fact that you can only be a good scientist when you are an atheist, or at the very least an agnostic. Any rational scientist would agree. Now we got that out of the way, I am very excited that CERN has discovered the higgs boson. This is a major step in the direction of understanding how this universe works. A good time to be alive!
The Higgs Boson is an excitation in the Higgs field - which is what actually gives mass to particles. The boson is the easiest to discover (kinda) evidence for the existence of the field. The boson is not disallowed from interacting with the field, which it does, which is why it has mass. Minutephysics' series on it is worth a watch.
Gandalf just taught ne about Higgs bosons!
@eleerzaa (1) The gauge group that represents the EM force. A gauge group is a symmetry group, a group of objects that are unchanged by a specific transformation. Spheres are a part of O(3), the rotation group. The group representing the EM force is called U(1). The weak force is described by SU(2). In the early universe, these were combined into the electroweak force, with group U(2). (cont.)
Hey, I am a Christian, and my faith motivates me to learn, and the more I've learned about this world we live in, the more I have come to believe that there must be a God. If you take it mathematically, and think about the chances of the thing we call life occuring, the chances are so small that you conclude that it has to be set in motion by a greater force. I agree, some religions do take advantage of people (scientology, etc.) but true Christianity only teaches peace, learning, and respect.
I have watched 20 Higgs explanations , and tours is by fae the best.
This was the most comprehensive explanation i have heard yet even i was able to grasp the concept from other videos i find that this makes more sense
I bet he wore his best T-Shirt for this video. Bless him
why only 240p :( ? This topic is worth at least 1080p, if not 4k.
Folks, here is a particle that through its asymmetry, slides like a neutrino through normal matter, and when then perturbated in orientation, immediately becomes 'real'. This means that when 'harnessed', it can be polarized to near zero mass and spun up to light speed, then when 'rotated', it will flash into 'existence', with a HUGE mass. We may never harness anti-matter, but we CAN harness this, which would be the second highest energy storage device in our ability to do further work.
@gravytrain84 Since Higgs bosons are scalar bosons (they have no spin), they can participate in interactions with other Higgs bosons. These interactions, through Feynman loops, give them mass in the same way mass is given to fermions.
i get it. in the desert where i live the skier would be a sidewinder traveling over the snow. and the second guy would be like walking through tapioca. how long you cook the tapioca would determine how deep you sink into it.
Isn't the process of drawing conclusions through experiment just ruddy marvelous!
My uncle works at CERN. Hurray. Just been out with him and his co-workers nerding about this.
Space, like tonal space in music theory, is a harmonic structure. So the further back in time we look, the "stronger" E is relative to itself in the lower octaves. And the effect is real as the mathematics of dark matter shows explaining why its "missing". The only thing really missing is the answer to why DM does not exist, and that's not even missing if you look real close. E=mc2 is unit of measurement, to enter the strong force it takes time and E=m+{a}c2 as CERNs N @ v-c/c=2.48e-5 sec showed
my respects John Ellis ... to know what you know and to to teach what you teach ... respect and more respect.
The mass is converted from the energy in the collision of two protons, by E=mc^2.
Yes, the boson does interact with its own field.
Thank you for this , when you shovel this snow a substitute must be present,this opens many doors for me thanks again.
Weight is the consequence of the effect the higgs boson has on particles without 'weight' or mass. Weight is not a force, but rather, it is a behavior that particles express when effected. Weight is an illusion to make sense of the world around us, and the higgs feild and resulting boson from interacting with particles causes the behavior we interpret at weight.
'That guy' is John Ellis, a quite renown theoretical physicist and an important character in CERN's theory group.
it s increadable as people can make jokes with anything and disfocus of the point. May God bless
!!!
The higgs boson is a bit hard to put into classical physics understanding, but is a consequence of the higgs field. The higgs field permeates the whole universe, and movement and interaction in this field can cause particles to acquire mass, kinda like how walking through mud makes your foot heavier. To get technical, the higgs boson allows multiple identical particles to occupy the same space with the same state. This breaks the electroweak symmetry which... sorry, told you it's hard to explain
quarks are like tiny little bits of mass that combine to form hadrons, the most stable of the known hadrons are protons and neutrons! There are 6 types of quarks, and they are known as flavours: up, down, bottom, top, strange and charm. Up and Down are the most stable of all the quarks in the universe and the other 4 are only created in high energy collisions, particle decay then rapidly happens decaying the 4 rarer quarks of the 6 until they are up and down quarks themselves.
Why nobody talking about that the name Bosom comes from an Indian scientist Dr Bose who died in.1979. He deserves an equal amount of recognition for the discovery of Higgs Boson, The original idea for Higgs Bosom comes from Hinduism and Dr Bose was the one, who introduced his idea to Dr, Higgs
i think he was saying the speed of these particles is what causes different levels of interaction with the field
This is incredibly well explained.
One of the easiest way of understanding Higgs boson
To be honest, over the next two weeks for school holidays I need to present a slideshow on this, Thank You John Ellis and Scientists at CERN :)
@tripelb1 The Higgs field interacts with particles to give them mass, the Higgs Boson is an individual excitation o the field. The Higgs field originally had four degrees of freedom - but three of these became the masses of the W ad Z bosons, the particles that carry the weak force. That's the primary function of te Higgs field - to break the electroweak fore into the electromagnetic and weak forces. The remaining DoF became the Higgs Boson, and couples to matter fields.
@jdistler123 The photon doesn't interact with the Higgs field because it belongs to a different gauge group. The Higgs gives mass to particles by breaking the SU(2) group, but the photons interact via the U(1) group. Same goes for gluons, which interact through SU(3).
@granand Remember that the Higgs field is what takes a value everywhere and interacts with particles, breaks symmetries, etc. The Higgs Boson is what we call in quantum mechanics, the quanta of the Higgs field. Similar to the way photons are the quanta of the EM field, or fermions are quanta of fermionic fields, the Higgs is the quanta if the Higgs field.
u are completely right,,i misunderstood what he said first and then i continued with the error ,,thanks for pointing it out
but what IS hogg's bison?
Very deftly explained prof. In an enjoyable and interesting form.
The particles with integer spin, are governed by Bose-Einstein statistics, hence the name bosons. The Higgs boson is a spinlees particle, as zero is an intenger, the Higgs boson is a boson.
Thank goodness. I've been hearing the term here and there, but never looked into it (Can't say I watch much news) but I'm glad this video taught me what exactly the big fuss was about.
A "particle" of light is constantly spinning round an centre external to it, as demonstrated by polarisation. An electron is also spinning round a centre external to it, and has little mass. A nucleus on the other hand is so close to its centre of spin that the centre is within the internal to the nucleus. Could this kind of observation not alternatively explain mass as a physically induced attribute rather than a particle.
The particles that dont pass smoothly through the higgs bosons should encounter resistance if I understand all that right. That means if you could create something that emits said particles it might be a more efficient form of propulsion in space than say rocket fuel. The particles would encounter resistance from the higgs bosons and could push a body through space.
@Arachnalicious That isn't totally correct. Particles receive mass from the Higgs mechanism, the process by which SU(2) (the summaries of the weak force) is broken, giving a large number of particles mass. (U(1) and SU(3) were untouched by the Higgs field, so photons and gluons never gained mass and therefore do not interact with the Higgs Field.)
Thank you. Most appreciated. You have read a lot then and some really interesting books. All the best in your continuous study.
what gave that impression? i'm not weak enough to get upset other a fight with a person on the internet. in fact this actually immensely amuses me. carry on.
Space is relative to time so no two particles in separate space exist at the time just like frames in a movie. And if you observe (measure) using time and the particle does not get bigger it will measure smaller. But Ohm's law is V=IR not V=IxR and space expanding so we have measurements that agree...almost. The neutron still measures larger than the proton. So something is causing that and it's called a harmonic comma. And because the 2nd is bigger than the 1st we have the force of gravity.
@deyomash Yes, you're correct. Through the breaking of the SU(2) symmetry (the group that corresponds to the electroweak forces.), the Higgs Boson gains mass, and interacts with the Higgs field.
From what I understand, particles acquire mass when they pass through the Higgs field and are essentially slowed down by it, which manifests itself as mass. So logically, a particle would have no mass if it's not moving through the field. If my thinking is incorrect, then the video is misleading.
@GreatestTop Most of the mass of a proton doesn't come from the quarks that make it up (which get their mass from the Higgs field). Most of the mass of the proton comes from the binding energy that holds quarks together. Since E = mc^2, this contributes to the mass of the proton. No, The Standard Model offers no DM candidates.
The Higgs boson endows particles with mass, which gravity can subsequently affect. We need analogies precisely because it's difficult to understand this kind of counter intuitive idea. It's like the hydraulic analogy which is often applied to electricity, that is, useful but not to be taken too literally. There would still be a Higgs field even if there were no Higgs boson, since there is no proof that wave particle duality holds true for all waves
I failed chemistry exam at my school but clicked subscribe and bell button. How dare i am😨
I realize that the amount of interactivity with the Higgs-Boson is what gives particles mass, but why exactly do some particles pass through the field with little resistance, while other particles of the same size pass through it with a high level of resistance?
Everytime I watch a video like this I feel smarter
I still think the 4 Maxwell Equations are more elegantly presented.
they investigate what implications it has (for example on the standard model) and if the Higgs can be used to try to derive a theory of quantum gravity.
Happy belated birthday John!
Good explanation, I would struggle to repeat this to anyone, but thank you John.
Light doesn't bend; the space in which it propagates does. A black hole is a region of spacetime so distorted that you could say that every direction becomes "down". Gravity never reaches a zero-value either, so if you can see it, then you're experiencing some degree of gravity from it. Even if that value is infinitesimally small.
"What is the Higgs boson?"
"Everybody's favorite Boson", Penny, The Big Bang Theory
His explanation uses so many analogies that his explanation is wrong. For example: the Higgs field isn't made up of Higgs boson. The quantisation of Higgs field gives rise to the Higgs boson.
Here's the information I understood, if someone else can correct me, please do:
Prof. Ellis is basically stating that the Higgs boson is a particle that gives mass to other particles. Correct?
This man is science personified.
@julianlobo91 @deyomash The Higgs boson gained mass through the breaking of the symmetry between the weak force and the electromagnetic force. (called SU(2)). So, just like all other particles, it interacts with the Higgs field. Similar to the way gluons can interact through their own field.
Nice one. Some people come here to learn so let's be respectful to them
Yes it does result in more questions. That's the beauty of Science. The more you know, the more you know how much you still don't know. :)
All of the commentors are so smart compared to me. Using words like belittled and analogy. And they actually use periods! I like this group.
Thank you for this. The snow analogy made it very clear.
It isn't a case where we point at a collision and make up logical explanations based on what we "think" happens. There is data.. sure, the data does not say "aha, there is a quark!," but we can identify different properties of things that come out of the collisions.
Also gravity affects energy and momentum - two properties that mass usually has.
Best explanation I've seen so far
A dimension is like length, width, and height, we view things in these 3 dimensions. If someone were only able to see two dimensions they would not be able to tell a disc and a ball about as they would both look like circles. So let's say this guy is seeing a basketball, his 2D mind sees an orange circle. Likewise, if I were looking at that basketball in 4 dimensions it'd look different but it is still the same basketball. Dimensions are NOT places or alternate realities or universes.
The Higgs bison is one of the friendliest of all water buffalo
@kirstenlopez Yes, roughly 126.5 times the mad of the photon. The Higgs field interacts with individual Higgs Bosons (or, if you prefer, individual Higgs couple to each other) through the weak interaction, giving them mass. The most interesting thing about the discovered Higgs mass is that it's less than the SM Higgs, but is in the range of a supersymmetric extension to the SM.
This is the standard model - what of it you find unfinished or clumsy is an opinion that hardly any physicist will share.
no, imagine you have a proton in a higgsfield. This particle moves in the higgsfield and will 'touch' the higgs bosons. The way the proton reacts with these higgsbosons determines the mass it has. For instance a neutrino almost has no reaction with the higgsfield so thats why it is almost massless. But if you have a top quark, which is the 'heaviest' of all the particles, will interact a lot with the higgs field. Search for the fermilab explenation on youtube, it s a better analogy i think
2 questions: first, what about matter determines how much it interacts with the Higgs field to obtain mass. second, since the Higgs bosons have all decayed, what maintains the Higgs field in the absence of it's particles?
now that IS the proper look of a professor
Ohhh, of course. Now I get it! His t-shirt explains everything.
and yes, you would be right if you would have said that one person is not identical with his caricature. but since we know where the countless caricatures named pere de noel, weihnachtsmann, santa claus etc. come from it really makes no sense to discuss that further. thank you for taking so much time for semantics.
In other words, Mass is the interaction of particles with the Higgs field. No interaction, no mass. More interaction, more mass.
the higgs boson isn't rare, its ubiquitous. the higgs field is everywhere around us, extends as far as the edges of the universe. the higgs field is composed of higgs boson particles as the ocean is composed of countless amounts of h2o molecules.
The establishment (LHC) is only needed to CREATE the higgs boson, by smashing particle beams against one another, not only to measure/observe it. The higgs boson was found by smashing these beams allowing the sensors to pick it up for the first time.
According to the explanation and the given example, particules which interact with the Higgs field do not aquire more materia, but behave as if they would. Is what we call "mass" the consecuence of an interaction with the field and not an increase of materia in the quantic conception?
Sorry! Could you please repeat all that? I understood everything except what the subject, message and the whole point was about.
