I happen to be of the considered opinion that programming is one of the more difficult branches of applied mathematics, because it is also one of the more difficult branches of engineering, and vice versa. When I tried to explain to one of my mathematical colleagues why I held that view, he bluntly refused to listen to my arguments and, instead, blamed me and my fellow computing scientists for not yet having designed the programming language that would make programming as easy as it should be! Should I have asked him, why mathematicians have not developed a notation that would enable everyone, no matter how ill-equipped otherwise, to do mathematics?
