quarks and one up quark and they are also held together they are held together by gluons gluons are the strong nuclear force analog of the photons of the electromagnetic force So within nature you see this pattern played out over and over againthere are different levels of structure where you have particles that are Fons taking up space held together by bons carrying
have no experience with them. One is the strong nuclear force , which holds the nucleus of the atoms together, and the other one is what we call the weak nuclear force , which is responsible for some types of radioactivity. And since most people don't play around with nuclei, and most people don't play around with radioactivity, they don't know what that is. But by the '30s, scientists had done enough experiments, done enough theorizing
that's where we were. There were the four forces. So we move ahead, and in the late '50s and early '60s, some people were thinking that maybe the weak nuclear force and electromagnetism actually were the same. So they were working on trying to bring together these two forces to show that they're connected.
and how those fundamental particles combine and interact. We also talk about the strong nuclear force that holds the atomic nuclei together as one of the fundamental forces involved in fusion. But that mass defect, E=MC², we know from Einstein, is also energy. And so, in that process, a tremendous amount of energy is
But there are two other forces that only have any real importance inside the nucleus of atoms, which is why most people have no experience with them. One is the strong nuclear force , which holds the nucleus of the atoms together, and the other one is what we call the weak nuclear force , which is responsible for some types of radioactivity. And since most people don't play
The individual protons and neutrons are made of quarks, up and down quarks, which are held together with the strong nuclear force . Occasionally an up quark or a down quark can convert into the other one by the weak nuclear force and give up a neutrino in the process. Everything is pulled towards everything else by gravity.
I do. The first one could lead to an accidental war, or a war by miscalculation. And so none of us who have been in this field have been much concerned about the Chinese nuclear force
And so conserved CPT as a whole. But in 1956, theoretical physicists Tsung-Dao Lee and Chen-Ning Yang realized that no one had checked whether parity is conserved in the weak nuclear force . So they set out to test whether the universe favored left or right handedness.
But it wasn't until 1967, so three years later, that Steven Weinberg and some others actually unified electromagnetism and the weak force. - Sheldon Glashow, Abdus Salam, and Steven Weinberg successfully unified electromagnetism and the weak nuclear force that showing that at high energies- - Right - ... these two forces were merged into a single electroweak force.
Whatever planets have water, it looks more and more likely like a lot of them do. What an incredible future, just out into the cosmos, nuclear power plants everywhere. Okay, so to linger on some of the technical stuff, you said strong nuclear force . So how exactly is the energy created? So how does the E=MC squared, the M go to the E infusion?
blackboard and totally divorced from the average person. They don't realize that everything about their life, about electricity, about magnetism, about the nuclear force , about industry, everything comes from physics. But the average person thinks that physics is for eggheheads. It's for equations you
And then that money can pay for probably free community college for everybody, maybe even free college for people. But just if you take the six major constants that-- you know, gravitation, the strong nuclear force , the weak nuclear force , the force, the dark energy force,
The electron is held together to the nucleus by electromagnetism. The individual protons and neutrons are made of quarks, up and down quarks, which are held together with the strong nuclear force . Occasionally an up quark or a down quark can convert into the other one by the weak nuclear force and give up a neutrino in the process.
And they only show up in what is known as the weak force. The laws of physics are broken down into sort of four fundamental forces-- gravity, electromagnetism, and the strong and weak nuclear force . And every one of them, except for the weak force, seems to not give any concern whatsoever about the
