To do mathematics is to engage in an act of discovery and conjecture, intuition and inspiration; to be in a state of confusion โ not because it makes no sense to you, but because you gave it sense and you still don't understand what your creation is up to.
Paul LockhartWhy don't we want our children to learn to do mathematics? Is it that we don't trust them, that we think it's too hard? We seem to feel that they are capable of making arguments and coming to their own conclusions about Napoleon. Why not about triangles?
Paul LockhartNo mathematician in the world would bother making these senseless distinctions: 2 1/2 is a "mixed number " while 5/2 is an "improper fraction." They're EQUAL for crying out loud. They are the exact same numbers and have the exact same properties. Who uses such words outside of fourth grade?
