Neither is it the right angle, which me attracts, nor the straight line, hard, inflexible, made by men.
What attracts me is the curve, free and sensual, the curve I find in the mountains of my country, in the winding course of its rivers, in the waves of the sea, in the body of the beloved woman.
The universe is made out of curves - the curved universe of Einstein.
(Oscar Niemeyer)
