I'm surprised by the downvoting on this thread. Kumarvr asked for examples of things math doesn't explain. Simple examples of things math doesn't (at this time) explain (e.g. psychology; dreams) were downvoted.

Why? There's no way to know why. Just downvotes. Maybe someone thinks math explains physics, which explains [...], which explains dreams. Maybe that's not it at all. Who knows?

I can only speak for myself here, but silly downvotes are the primary reason I'm disengaged with this otherwise really great site.
