"Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away"
- Antoine de Saint-Exupéry, French writer and aviator
one of my favorite quotes. The sentence following this quote tells us what he is writing about:
"Au terme de son évolution, la machine se dissimule"
I don't dare to translate it to English. In the German book, it's "Die Maschine in ihrer höchsten Vollendung wird unauffällig".
Достаточный минимум.
I do not know how to accurately translate into English.

A long time ago, this photograph was for me the first vivid example of a достаточного минимума.
