The Standard Model of Particle Physics (5 of 15)

Episode 5 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn how particle physicists have developed a theory that can explain almost everything in the universe in terms of just 12 particles.

particle physics gives me a hadron

[MilletGtr]

this is so exciting!

[Graham6762]

1.9 that is so fucking cold, that would instantly kill a person, all countries should use Kelvin

[simysimss]

love the video man

[chrispikeyp]

very interesting video thanks

[farenhai]

@shep312 Very clever!

[Asuperl33tninja]

@shep312 lol I see what you did there :P

@Mattsretiring

If you give the protons a lot of kinetic energy by accelerating them close to the speed of light then when they collide you can create new particles from the energy in the collision.

So it is possible to create any particle at all as long as you have enough energy there.

Everytime I watch movie with Dr. Brian Cox saying about physics, my moggy comes and starts mewing.

[Mattsretiring]

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?

[remoraid7]

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!
