Please think again before you decide to study "official" mathematics. There is a good chance you will waste your prime time on a huge pile of intellectual rubbish.
In the department of philosophy and mathematics new branches sprout as prolifically as lianas in the rain forest and there is a pullulation of techniques, terms and symbols producing a heterogeneous crop full of chaff that conceals a few kernels of wisdom.
