Mathematics is a place where you can do things which you can't do in the real world.

The point is with good maths skills you have just wonderful opportunities and if you don't have good maths skills, there are just so many things that you won't be able to do.

I studied international relations and economics at the University of Virginia. I paid my way by working as a bartender in the summer and at three part-time jobs during the year.

By pouring money and goods into devastated regions, foreign aid workers sometimes compound the disruption and debauch the survivors.
