Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.
William ThurstonThe product of mathematics is clarity and understanding. Not theorems, by themselves. ... In short, mathematics only exists in a living community of mathematicians that spreads understanding and breathes life into ideas both old and new.
William ThurstonThe real satisfaction from mathematics is in learning from others and sharing with others.
William ThurstonI think mathematics is a vast territory. The outskirts of mathematics are the outskirts of mathematical civilization. There are certain subjects that people learn about and gather together. Then there is a sort of inevitable development in those fields. You get to the point where a certain theorem is bound to be proved, independent of any particular individual, because it is just in the path of development.
