Topics include languages, music, technology, social studies, science, engineering, maths, journalism, and more. Most are about five minutes (some longer, some shorter) and cover topics like chemistry, physics, calculus, geometry, biology, Algebra, trigonometry, grammar, ACT prep, and SAT prep. Videos can be searched by topic or decade.

Line, Surface and Contour Integration “Find the integral of the function ” is a typical core thing one wants to do in calculus. But particularly in applications of calculus, it’s common to want to ask slightly more elaborate questions, like “What’s the integral of over the region ?”, or “What’s the integral of along the line ?”

For example, as transportation networks play a key role in moving goods and materials from suppliers to customers, Zach hopes to integrate models of global transportation networks into his models of global supply chain networks. There are many branches of maths, including algebra, geometry, calculus and statistics.

And indeed particularly in chemistry and engineering it’s often been in the background, justifying all the computations routinely done using entropy. There had been precursors of steam engines even in antiquity, but it was only in 1712 that the first practical steam engine was developed. Lazare Carnot died in 1823.

I should say at the outset that I’m going to focus on the big picture of what’s going on—and while I’ll mention some engineering details, I won’t get deeply into them. It turns out that the chain rule of calculus in effect lets us “unravel” the operations done by successive layers in the neural net.

It didn’t help that his knowledge of physics was at best spotty (and, for example, I don’t think he ever really learned calculus). His father ’s university engineering studies had been cut short by the Russian Revolution, and he now had a one-man wholesale electronic parts business. Petersburg; his mother in Odessa ; they met in LA).

Once one has the idea of “equilibrium”, one can then start to think of its properties as purely being functions of certain parameters—and this opens up all sorts of calculus-based mathematical opportunities. Class 4 shows behavior that looks more like the “insides of a machine” that could have been “intentionally engineered for a purpose”.
