Still, the course has critics. The students don't know formal math. Teachers can't use the language of science. For example, suppose I say that electricity flows in wires the way water flows in pipes. That's very clear, but it's only true when the pipe flow is laminar.
Water moves too fast for that in most pipes.
The pipe flow in your house is turbulent. To double the water flow you need four times the pressure. To double the current in a wire you only have to double the voltage. That would be so much easier to say in mathematics. I want to tell what took me years to learn.
