Say you were trying to teach yourself, to a 99th percentile *layperson’s* level, how, say, an electric car actually worked. How would you go about doing that, precisely?
I am not sure exactly how high (or low) a standard that is, but here is what I would do.
2. Read a book or two on how electric cars work, along the way finding an expert or mentor who could answer my questions.
3. If needed, read a more general book about electricity.
4. Try to explain to someone else how electric cars work. Try again.
I would recommend this same general method for many particular questions.
