Hello everyone! Thanks very much for checking out the channel!
The aim of this channel is to provide higher level physics content in a clear and precise manner. The content I will mostly be covering will be aimed at university undergraduate level, though there is also some A-Level topics.
I’m a first class physics graduate as of 2021, and I wish to share some of my understandings I had to help anyone achieve their goals without feeling a loss of enjoyment for the subject. Much of the content covered is very advanced, and so I hope I can deliver it as clearly as possible.
If anyone wishes to support the channel on an additional level, then I have a Patreon where supporters can gain additional bonuses including one-on-one support with any problems as well as requesting topics.
I hope that everyone can benefit from the content i provide on my channel.
Thanks for the video, derivations in books/notes I've seen only 2-3 pages long, however without commentary some parts are quite tricky and now entire lecture material feels very intuitive!
Hey I just came across your channel and I absolutely love your videos and teaching, I love how you explain every single topic in detail, and the length of the videos is perfect, but I think it would be nice to label the videos in a series according to the order, maybe like lesson 1 or L1 and L2 , cause I found it a bit challenging to find the order of the videos. Apart from that everything is good, pls don't stop !!
such a great video, just the right amounts of curiosity, intuition and mathematics, i love it! you explained this very well😊 many physicists lose their exitement for the subject, it seems, and get lost in the sea of mathematics, but you still got it, like richard feynman
im a music producer far away from maths trying to understand the E=Hf, i want to know how much energy per frequency of a soundwave, and how to put it on a graph from 20hz to 20Khz, can someone help ? very informative video tho !
Hey, good to have you back, looking all bright and healthy! Just wanted to say I passed my Thermodynamics course. Honestly, your playlist was a game-changer for me. Couldn't have done it without your Playlist. It was the only way I could understand the topic. Thanks a bunch
hello hello, a quick question at 41:00. looking at my notes, the Clausius Mossitti relation differs by a factor of 4pi. are your explanations written in SI or in CGS units?
So the entropy, S, is given by S = k_B * ln(w) Where w is known as the macrostate multiplicity (ie the number of microstates for given marcostate). So a given system in thermodynamic equilibrium will want to maximise this quantity - and so will occupy the state which has the greatest number of choices!
I'm confused about how you're defining degrees of freedom. For an ideal gas, we had 3 degrees of freedom, but in the metal lattice you show in the derivation of the Dulong-Petit Law, you say there are 6 degrees of freedom? Why the difference? Furthermore, you mention at the end that in future videos there will be elements of QM. You mention that we will now assume particles are indistinguishable, but I thought we were assuming that for a while now? Isn't that what the point of the Gibbs factor (1/N!) is? These videos have been excellent in all other aspects and have hugely helped me navigate this difficult subject.
For the ideal gas, there are indeed 3 DOF. These include: motion in the x direction, motion in the y direction and motion in the z direction. Mathematically, this can be written as a Hamiltonian which has three momentum terms: p_x^2, p_y^2, p_z^2, one for each cartesian coordinate. In the case of an atom in a metal lattice, we model the atom as a harmonic oscillator. This means that in addition to the three momentum motion terms in the Hamiltonian, there are three additional terms which correspond to the elastic potential energy stored when an atom deviates from its equilibrium position in the lattice. Think the formula for the potential energy stored in a spring ½*k*x^2. But because we're in three dimensions, it would be ½*k*(x^2+y^2+z^2). These 3 terms, alongside the 3 momentum terms give rise to 6 degrees of freedom in total in the metal lattice. The key difference is, in an ideal gas there is no potential experienced by the particles, whereas in a lattice the atoms are bound by potentials caused by other atoms. I'll get back to the second part of your question when I rewatch my video!
Man you are the myth, the monster, and the legend. I hope you were my professor. I'm in awe after watching your videos. You are a savior. Keep uploading and helping us😁
7:05 Wrong. The issue is that the further you go up in frequency, the more energy would be expected to radiated out from the black body. The limit would be infinite energy emitted by the black body, and THAT is the "carastrophe." Also, the word "ultraviolet" was their time's way of describing photons beyond visible light. You're welcome.
Hey, nice video but Gibbs entropy formula does NOT have a capital N term. You missed saying that entropy is linear, and that you are takin N elements/systems, hence the entropy of ONE element / system is the actual formula of Gibbs, which does not have N, because you have to divide by N.
This series as a whole is incredible! In 2 nights I went from someone who got a bad lecturer in first year thermo and permanently put off any ambition to learn the theory, this has changed that to someone who is enjoying learning all these things I wish I knew in the first place! Amazing videos so far!
Boltzmann Distribution Hey Pazzy, does this model look like it might describe the math in your lecture? Thanks for your well produced video. Your viewers might enjoy seeing my personal amateur science project. Sorry if it’s not a well produced video I need to do better. It might be a good visual aid that the math describes. See linked below. It uses a sheet of spring-like material buckled from the ends to form a Gaussian curve. The area under the curve represents the energy in the system. The sheet of material represents a field with the ends bounded. Seeing the mechanical effect may takes some of the mystery of what the math for your students. See the load verse deflection graph in the white paper found elsewhere on my RU-vid channel. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wrBsqiE0vG4.htmlsi=waT8lY2iX-wJdjO3
Is it me just wildly speculating or does this actually relate to your lecture and subject? Particle in a box model Thanks for your well produced video. Your viewers might enjoy seeing my personal amateur science project in the visual aid linked below. It uses a sheet of spring-like material buckled from the ends to form a Gaussian curve. This is to represents a two dimensional field with the ends bounded. Seeing the mechanical effect may also takes some of the mystery of what the math is showing.
