There is geometry in the humming of the strings.
If all art aspires to the condition of music, all the sciences aspire to the condition of mathematics.
Besides language and music, [mathematics] is one of the primary manifestations of the free creative powers of the human mind, and it is the universal organ for world-understanding through theoretical construction. Mathematics must therefore remain an essential element of the knowledge and abilities which we have to teach, of the culture we have to transmit, to the next generation.
