Back in the 1990s, the Digital Libraries Initiative from the National Science Project supported a small project out of Stanford University. It sounded obscure, and a lot of people thought it wasn’t exciting, and would have little real-world application. But on that team were two graduate students – Larry Page and Sergey Brin – the founders of Google.

The modest grant ended up paying off very well, according to Robbert Dijkgraaf, a physics professor and the director of the Institute for Advanced Studies at Princeton. He recently wrote a companion essay to Abraham Flexner’s 1939 piece, “The Usefulness of Useless Knowledge,” explaining why Flexner’s ideas are even more relevant today.

We talk with Dijkgraaf about why governments should fund more basic research that doesn’t necessarily have immediate results, like the project at Stanford – and how it can actually reap huge rewards in the long run.
