The Weak and Strong Nuclear Forces (9 of 15)

Episode 9 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 the string and weak nuclear forces were discovered.

This film is part of a series originally broadcast on Teachers' TV (http://www.teachers.tv/video/23645).

The series was made with the support of The Science and Technology Facilities Council (www.scitech.ac.uk).

2000 years = ridiculously brief period of time

5-6% of observble universe = an unconceivably large portion of our world

[nurbsenvi]

So it took us nearly 2000 years to understand 5~6% of the observable world...

[craigz06]

so that's what the strong force is, thanks

[thedeadlystoat]

I just came here to listen to Dr. Brian Cox saying the word 'atom'.

[EarosioN]

@MrDgaf12345 we havent existed for even 0.1% of that time

[sbergman27]

This is why I keep watching science videos. I've studied a lot of physics, but was unaware that the weak nuclear force was involved in nuclear fusion. Between now and the next video, I will maintain an attitude of scientific skepticism. I expect that the next video will probably provide the necessary evidence to overcome that.

[MrDgaf12345]

@nurbsenvi no, more like it took the universe 13.7 billion years to understand 5-6% of itself if we are the first

Lol Professor Cox workin out in the gym, breakin a mental sweat

[Tr4newreck]

what happened to his show... wonders of the universe...

[omgthatscrazyx]

That guy looks so out of place in the gym lol

[BPMa14n]

Is there any theory wich states that every atom is a black hole -ish vortex and that the proton and neutron are held together by the strong force actually being similar to a vortex force negatively charged. Also the electron dowsnt go in the center because the vortex is negatively charged but stiull the protons in the middle atract it enough to orbit it?

@weicek37 oh right okay, so that's why in fusion there is a greater amount of energy realesed, due to the fact that elements have a greater binding energy as they get bigger ( closer to iron) and when they get so big like uranium, they have a lower binding energy and so when fission occurs they move closer to iron again and release energy, but not as much as fusion?
