if you took a notebook, a plastic bottle, a toaster, and a glass container and burned them in a fire hot enough, around 10^31 degrees Celsius, all the particles and forces, would become one entity. This is what...

Ordinary matter that we experience around us is really just made of 4 particles, the up and down quarks which make up the protons and neutrons in the nuclei of atoms, electrons which form a cloud around the...

The Dirac equation holds the secrets to everything that we can see in the universe. In this video, I show how with this equation, we can start with a completely empty universe, make just one assumption, ask just one simple...

QCD: Quantum Chromodynamics. How can positive protons be so close together in the nucleus, if they repel each other? Japanese physicist and Nobel laureate Hideki Yukawa sought to answer this question. He proposed...

If you ask a physicist, what is at the core of physics, you will hear symmetry. What is symmetry? Gauge theory explained simply.



Symmetry is about actions that don't change anything. If we take an...

What is the Electroweak force? Electroweak theory explained: At the moment of the Big Bang, all 4 fundamental forces were probably the same. But as temperatures and energies lowered, the forces separated into...

Does a final theory exist that can end our reductionist probing into ever shorter distances? Or is there no end to reductionism? There should be an end point because as the object of our measurement gets small...

Summary:

Everything you can see is made of up of the same fundamental particles. The best theory of fundamental particles and forces is the Standard model of particle physi

Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory? Let's find out.

We've already learned about different types of chemical bonds, including covalent bonds. But now that we know about enthalpy, and orbitals, and some other concepts, let's revisit the covalent bond and dig a little deeper.

If higher dimensions exist, they aren't what you think - Exploring Worlds Beyond Our Own

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's...
