In this video, we look at nuclear fission and nuclear fusion. First we explore how nuclear fission works and what is meant by a chain reaction. We then look at examples of controlled and uncontrolled nuclear fission. Finally, we explore what is meant by nuclear fusion.

In this video, we start looking at waves. We explore the key differences between transverse and longitudinal waves. We then look at how when a wave travels, the wave moves but not the medium.

A simple and clear explanation of all the important features of quantum physics that you need to know. Check out this video's sponsor https://brilliant.org/dos
I have spent a lot of time thinking about how best to explain quantum physics and this is the result of all my hours of pondering, and I’m really happy with how it turned out. I decided to just explain it as it actually is, rather than rely on analogies. The video explains the quantum wavefunction, particle-wave duality, the measurement problem, the double-slit experiment, superposition, entanglement, quantum tunnelling, the Heisenberg uncertainty principle, and energy quantisation. Let me know if it was helpful! Cheers Dx

Further reading
For a more detailed introduction to quantum physics: 'The Quantum Universe' by Brian Cox and Jeff Forshaw is good.
And a slightly more advanced but fantastic description of what we do and don't know about quantum physics is the excellent book 'Beyond Weird' by Philip Ball.

In this lesson, you will learn an introduction to physics and the important concepts and terms associated with physics 1 at the high school, college, or university level.
We will review Newton's laws of motion, projectile motion, force, energy (potential and kinetic energy), gravitation, momentum, collisions and more..
When you fall thousands of feet from the sky, it seems like something strange is happening with the laws of physics. Turns out, everything relies on a simple force - DRAG!

Quantum gravity is the hardest problem in physics. It's the attempt to unify the two pillars of modern physics: quantum mechanics and general relativity. It's the study of how gravity works at the quantum level, where the laws of physics are very different from what we experience in everyday life. One of the biggest challenges in quantum gravity is that gravity is the weakest force in nature. It's so weak that it's impossible to study for particles in the lab. We can only see its effects on very large objects, like planets and stars. Scientists have been working on quantum gravity for decades, but they haven't been able to come up with a complete theory. So it remains one of the biggest unsolved mysteries in physics, one that scientists are determined to solve.
