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."

"Friendship is built on trust and honesty."

"True friendship is worth more than gold."

"Good friends are like stars, always there even when you can't see them."

"Friendship means sacrifice."
