The Standard Model of Particle Physics (5 of 15) 

I've learned a lot from this :)

The idea of quantum physics is that matter is not continuous, but made of tiny discrete fundamental particles that are indivisible.. We cannot cut them into half using a knife because the 'sharpness' of the knife is limited and can never cut quarks or electrons into half.. The only way to break these particles apart so that we can see what is inside of them is to smash them together..

this is so exciting!

I was watching this video then at 1:12 I heard the dude say "hundred" I immediately thought Holy shit it's Brian Cox!

I love this! I love this. I love this!!!

I don't understand what is meant to be discovered by colliding protons. If it is know that protons are made of elementary particles (UQ and DQ) what is likely to come out the other side of a collision, except these particles?

@pab7984 At smaller and smaller distance scales momentum become more and more uncertain. The chances that a particle will pick up enough speed to get out becomes ever greater. Basically at some point it would take a force stronger then any that exist to keep these particles in a small enough space.

Could you take an electron micrograph of the electron itself?

Atoms; but subatomic particles are smaller than them- i.e. top quark, bottom quark (which makes up neutrons, and protons), electron, electron neutrino, charm quark, strange, quack, muon etc...

@orlandorjames Because no chemical or even nuclear process could extract the energy out of the quarks. It would require breaking the bonds between the quarks, which would take far more energy input then you'd ever get out of it. This would also sent neuron on fire.

Just wait two years to see what cool things they find! Like remember the Higgs Boson? Well.... ah never mind, I won't spoil it for you.

If by collisions, we don't get more particles than we have originally smashed together, no matter how hard we smashed, we know that these particles are most probably fundamental or indivisible.. to give you an idea of the distances we are probing.. It's approximately 2.81794 x 10^-15 m.. Thats about 3 millionths of a billionth of a meter... That's cutting a meter into half about 47 times!

@violentauntie Classical mechanics (the old laws) explain very accurately our world that we usually see - fairly large sized objects and low speed. When the speeds become sizeable relative to speed of light, classical physics completely fails, and we need a new model - relativistic mechanics. At extremely small sizes and low speeds we have quantum mechanics. At small sizes and large speeds - quantum field theory. None of them is right or wrong, they just fit reality better at that dimension.

How does the LHC gather data? Dr. Cox described the detectors as "taking 600 million pictures a second" after the collision. But doesn't introducing so many photos effect the result of the experiment?

1XAJAVIER: i love this video! I love chemistry

The sound at 53! IT's from a game named AIRFIX DOGFIGHTER!!!!!!

the world of the large , the stars , galaxies and stuff ... its limited to us ...we have a horizon ..we cant see past the cosmic microwave backround ...for several reason but the main one is the expansion of the universe but the world of the small ...is still strange and misterious to us. so i think its more important to discover everything we can about how particles work before we think about big stuff again.

every particle type has it's own personality. Inside a detector it's a particle party.

@cheasea Absolutely correct!

@pab7984 I guess quarks are just energy? idk and string theory those strings are like the DNA of the universe, the fundamental building blocks of the universe. so those strings are jus the smallest things imaginable cuz we'll never be able to see them, even with our most powerful microscopes that we have or we will ever have

finally switched it on today :-)

SUPER VIDEO JE RECOMMANDE

@shep312 Very clever!

1XADOCTOR amazing!

@sidewaysfcs0718 I agree, but really, I think we should focus on everything. We're a species of information, of discovery, that is what we do best and that is what we should focus on, only problem, we're still too dumb to understand that we yet don't understand. If our focus as a species was to discover the beauty of existence, instead of trying to take it for our own individual selves, then there would be no desire of hoarding it all, allowing us to experience the full depth of being

It sounded more like a Star Wars Tie Fighter Blaster.

1XE SISON: wow!

Interesting. But, isn't the idea of "no size" an oxymoron? If Quarks exist then they have a size. If they are physically "there" then they can be cut in half, and those "pieces" also can be cut in half...and so one and so forth, forever. No?

2:05 : Twenty-seven kilometres of tunne... in circumference?

i hope they'll find out why the identical particles are heavier in difference. -alfabeto Chem 51 AGC

That is a pretty big hadron

so which is smaller, atoms or DNA?

I'm a lawyer, not a science person, but, If there is an infinity in both directions (big and small, or out and in?) then isn't there an infinite amount of particles to discover? The atom is made up of protons and neutrons, which are made of quarks, which are made of....??? Get my point? Then string theory says all matter and energy is made of tiny vibrating stings. But what are the stings made of? And what is what makes the strings made of? It's an infinity, right?

@Zayin1993 It is well over 9000.... kph

good series but to learn about quarks ill have to stick to my textbooks lol

@jockedahl123 thank you

@shep312 TURBOPUNS!!!

@shep312 lol I see what you did there :P

newtons laws arent wrong ..they just dont explain in detail how gravity works ....

Does anyone know where the four forces and the particles of the standard model come from? Please someone explain this. Explanations of the Big Bang given by physicists state it started from a "singularity", but then contradict themselves by saying they don't know anything about what happened prior to an infinitesimal part of a second from the beginning of the "bang". Then they start talking about cooling, etc., after that time, that produced "dust", blah blah blah. They then say that hydrogen came about, blah blah blah. OKAY, but where did the electron, proton, and neutron, come from to produce the element???? Where do all the exotic particles, quarks, leptons, bosons, etc. come from??? Please no BS!

this guy looks young but hes got grey hair...kinda like this kid i went to school with. he was like 16 but had bunches of grey hair.

no sorry i ment 1:53

holy fk 600million frames/s...

sounded more like the clack of a billiard ball.

The awesome Carl Sagan was replaced by this kid....

the outer is the source not theinner just trust me. factor that in for everything and it all makes sense. think about it. think the universe like a hologram a human would look out and be blinded by the outer wall and the sun would help light things around us my girl is deaf and if i stand in front of the sun shhe cant see my lips so think the original light source as the darkness of space we need stars to see around us like a hologram we are blinded by the spotlight that created us

Who are the 3 inch worms who disliked this video?

@shep312 OLD

how i wish im as smart as them haha -serina chem81EB1

oww man he looks pretty young....i bet when hes 90 he'll look like hes 40, but his hair will be as white as Gandolf's.

yo chris come and find me

he’s cute

Im all for education but how exactly is this so important to loose sleep over?Are people that desperate to find the truth to existance?You will learn or you wont once you die.Thats it.
