4. Massachusetts Institute of Technology
With 81 former MIT alumni having become Nobel laureates so far, the Massachusetts Institute of Technology is one of the most selective universities in the world, accepting less than 8% of applicants. MIT has rich traditions and offers students quality educational opportunities in the areas of physical science and engineering among others. There are many MIT alumni that have gone on to start incredibly successful businesses.
