Princeton Innovation, the October supplement to PAW, amazed me with the number and variety of cutting-edge projects being undertaken in a wide variety of fields, from making pure oxygen from water to extracting lithium from salt water to reimagining public toilets in the Third World. For a history major who steered very far from engineering, the projects are intriguing and sometimes mind-boggling. Entrepreneurship at Princeton, powered by some impressive minds, is alive and very well.
