9. What composes
software
development?

10. Computer
● To compute: to calculate, to reason → computer would be a machine to calculate
and reason
● Mathematicians won the war. Mathematicians broke the Japanese codes... and
built the A-bomb. Mathematicians... like you. The stated goal of the Soviets is
global Communism. In medicine or economics, in technology or space, battle
lines are being drawn. To triumph, we need results. Publishable, applicable
results. - Hellinger - Beautiful Mind

11. Engineering
● Patterns
● Scientifical
● Reproducible
● Quantifiable
● Principles
● Design
● Build
● Create
● Improve
● Evolved from Art

12. Technology
● (Greek) Tekhnē - technique, art, craft
● (Greek) -logia - subject of study

13. Code
● “As you will find in multivariable calculus, there is often a number of
solutions for any given problem.”― John Nash - Beautiful Mind
● The mythical man month - The joys of the Craft
● “I like solving problems, Commander. And Enigma is the most difficult
problem in the world.” - Alan Turing - The Imitation Game
● The art of computer programming - Donald E. Knuth (fundamental,
seminumerical, sorting and searching, combinatorial, mathematics
preliminares redux, backtracking, dancing links and satisfiability)
