A good problem is something you don't know how to solve. That's what makes it a good puzzle and a good opportunity.
Paul LockhartThere is nothing as dreamy and poetic, nothing as radical, subversive, and psychedelic, as mathematics.
Paul LockhartMathematics is about problems, and problems must be made the focus of a student's mathematical life. Painful and creatively frustrating as it may be, students and their teachers should at all times be engaged in the process - having ideas, not having ideas, discovering patterns, making conjectures, constructing examples and counterexamples, devising arguments, and critiquing each other's work.
Paul LockhartThe thing I want you especially to understand is this feeling of divine revelation. I feel that this structure was "out there" all along I just couldn't see it. And now I can! This is really what keeps me in the math game- the chance that I might glimpse some kind of secret underlying truth, some sort of message from the gods.
