“If you find that you're spending almost all your time on theory, start turning some attention to practical things; it will improve your theories. If you find that you're spending almost all your time on practice, start turning some attention to theoretical things; it will improve your practice." D. Knuth
In fact, my main conclusion after spending ten years of my life working on the TEX project is that software is hard. It’s harder than anything else I’ve ever had to do.
Knuth, Donald (2002). "All Questions Answered" (PDF). Notices of the AMS 49 (3): 320.
What were the lessons I learned from so many years of intensive work on the practical problem of setting type by computer? One of the most important lessons, perhaps, is the fact that SOFTWARE IS HARD. From now on I shall have significantly greater respect for every successful software tool that I encounter. During the past decade I was surprised to learn that the writing of programs for TeX and Metafont proved to be much more difficult than all the other things I had done (like proving theorems or writing books). The creation of good software demands a significantly higher standard of accuracy than those other things do, and it requires a longer attention span than other intellectual tasks.
—Donald Knuth, Keynote address to 11th World Computer Congress (IFIP Congress 89).
Programming is one of the most difficult branches of applied mathematics; the poorer mathematicians had better remain pure mathematicians.
--Edsger Wybe Dijkstra, EWD498
The easiest machine applications are the technical/scientific computations.
