I understand the basic laws of physics, and I understand the premise of internal combustion. Sure, there are a lot of details that I'm missing, but I get the basic idea. Similarly, I may not be able to design a modern processor from scratch, and I don't have the time to build my own robust Web framework, but I know at least the basic idea of every layer. That's enough to make me comfortable using a framework. I don't have to be intimately familiar with every line of code, at least to begin with, I just need to understand how it works in broad strokes.

Your knowledge of basic physics is a function of your education and merely coincidental that it could be of help in understanding internal combustion engines...unless you purposefully took physics classes for this reason.

Abstractions are a basic requirement for any sort of advancement, there is no inherent virtue in knowing what's under the hood unless you have a good reason to dig deeper.

When you get sick you take drugs that may actually kill you, you don't say I am not going to take this pill because I don't know how it works. Heck, I have no idea how the lowly Tylenol works and I take it all the time:)
