It is my understanding that at top schools like MIT at Berkeley, EE and CS are actually combined into a single undergraduate degree.

e.g. "The Berkeley EECS major, offered through the College of Engineering (COE), combines fundamentals of computer science and electrical engineering in one major."

The fact that they are combined to form a third program underlines the point.

Remind me where CS came from again?

This is the old debate of whether CS should stand for Computer Science ( chips / signals / digital electronics ) or Computing Science ( algorithms / language design ).

Mathematics?

Philosophy.
