A woman who could always love would never grow old; and the love of mother and wife would often give or preserve many charms if it were not too often combined with parental and conjugal anger. There remains in the face of women who are naturally serene and peaceful, and of those rendered so by religion, an after-spring, and later an after-summer, the reflex of their most beautiful bloom.Jean Paul Richter
Abstraction is the process or result of generalization by reducing the information content of a concept or an observable phenomenon.
- I discovered the works of Euler and my perception of the nature of mathematics underwent a dramatic transformation. I was de-Bourbakized, stopped believing in sets, and was expelled from the Cantorian paradise. I still believe in abstraction, but now I know that one ends with abstraction, not starts with it. I learned that one has to adapt abstractions to reality and not the other way around. Mathematics stopped being a science of theories but reappeared to me as a science of numbers and shapes. ~ Alexander Stepanov
- An abstraction is one thing that represents several real things equally well. ~ Edsger W. Dijkstra
