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.

For three centuries theoretical models had been based on the fairly narrow set of constructs provided by mathematical equations, and particularly calculus. In a sense, the concept of taking phenomena and drilling down to find their underlying essential causes is at the heart of reductionist science.

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.
