Holy cow. This is a needle in the haystack - there are tons of awkward explanations for this equation. Thank you.

Explained more in 8 minutes than my professor did in 2 days. Thank you!!

Excellent! It's much easier to explain in one dimension, then the partial in one dimension can be replaced with the Laplacian which makes it valid for three dimensions. Also, you are also easy to listen to. Good flow and good pace.

I think the PDE series, even the heat equation part, are not over yet, such as laplace equation isn't mentioned. hope you can make them up, that will be a great contribution for popularizing PDE. BTW, you have done a very great job!

Thank you! I feel like in lecture I (at best) follow the language as it's logically consistent. But here I feel like I have an actual understanding. So thank you for the effort put into these videos

In the end of the video you said there will be a derivation of the heat equation. I couldn't find any derivation of it in your channel. I request you to share the video if possible because you have explained it well.

Great video! I shared one of these explanations with my class. I linked to this video in a pinned comment. Did you ever get around to deriving the heat equation from the conservation of energy principle?

The layout of "Some new topic: Intuition" into "Same topic: derivation" is extremely pedagogical. Hope you're still teaching somewhere. You should really get in touch with Khan Academy to reach a big audience. This sort of material is invaluable.

I’m not sure if I have a wrong understanding, but online I’m finding many videos solving for the heat equation, but how do you actually find the temperature of a point x at time t?! Also what is the temperature measured in? Joules? I’m just looking for a way to actually use the equation. Very helpful video by the way!

If the change in temperature is proportional to the concavity, then why do the points of inflection change temperature?

Hi... Thanks for the explanation! I'm confused about the general solution though. I understand the math behind the derivation, but I don't understand the physical interpretation. In my book, it says that the value of the solution is a kind of weighted average of the initial values around the point x. How does this follow from the integral of the source function and the initial condition, and your animation? Please help!

Maybe I'm misunderstanding. He said the graph is a snapshot of the spatial temperature distribution (what the temperature looks like as a function of space at one instant in time). But when he explains the graph's shape he says "let's see how this temperature changes in time". He's using a temperature versus space graph to explain how the function evolves in time? How does that make sense? Feel like I'm missing something here. I'm a dummy so an explanation would be amazing. Thanks Bois.
@frizzleskillet185 жыл бұрын
Oh I think I understand. He's using the second derivative of the graph and showing how it relates to time. Because the equation literally says that the second derivative of the function with respect to space is equal to the first derivative of the function with respect to time. Gonna leave this here in case anyone else is ever confused about the same thing.

I think there is a h missing in the denominator of the definition of the derivative
