These are wonderful, wonderful videos, and your explanations of PDE's is just great. The intuition you give for what they mean and how to solve them really is delicious. I eagerly await more videos in the series (here's hoping that more are coming T~T)
@Zyphet The derivative u_x has units (units of u)/(units of x). This is because of the definition of derivative (partial derivative included) as a difference quotient. The second derivative u_xx has units (units of u_x)/(units of x) = (units of u)/(units of x)^2. In the case where both u and x are lengths, this is L/L^2 = 1/L.
@waspbr I use Screenflow and Corel Painter Essentials on a Macbook with a Wacom Bamboo tablet and AT2020 usb mic. Sounds fancy reading that, but it's $100 worth of software and $150 worth of hardware, not counting the laptop :).
Well you just solved all my doubts of differential equtions hope it works for my GATE paper ..
:) Thanks a lot ..

How did you conclude that uxx has the units of 1/L...
