Paul Erdos said mathematics is like a machine which converts coffee into theorems and proof. Marcus in his book "Finding Moonshine" says mathematician is a pattern searcher. Lord Kelvin asked the question, whom do you call a mathematician? He answered a mathematician is a person who finds the integral of e^(-x^2) from plus infinity to minus infinity as easy as you find 2x2=4. Is this what mathematics is about? Why is mathematics taught at university not related to the engineering course we study? Mathematics seems to be an abstract idea which does not overlap with our engineering course. Shouldn't it be taught in an engineering context?
