Quote by Brouwer, Luitzen Egbertus Jan

"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."

"The intuitionist does not accept the axiom of the excluded middle."

"Creating mathematics is like creating poetry or music."

"The act of intuitively creating a mathematical system requires freedom of thought."

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
