To become a world-class university takes a lot of time. There are simply no shortcuts. People tend to assume, and I have encountered this sort of thinking all over the world, that if they just sink enough money into a university, it will emerge in a few years as a first-class institution. But such rapid growth never happens. It takes time; it takes generations.

The rank of a university is similar to an index number say like the NASDAQ index. I don't understand how you can take an institution like Harvard, Stanford, or Michigan, and represent it by an index number. The concept makes no sense.

Public image is extremely important in American society and I observed personally that the Presidency of John F. Kennedy did much in the public mind for Harvard. Harvard was an excellent school before Kennedy, but Kennedy embodied a new vision for the United States: a leader who caught the world's imagination and that reflected on his alma mater, Harvard.

On the one hand, there is no question that English - frequently bad English - has become the universal language of scholarship. It is clearly a tremendous handicap for people outside of the United States, Britain, and Australia and a few other countries because few of them are native speakers, but we demand that they present and publish in English.

That said, there are a few clear factors that determine the potential of a university to reach the highest levels of excellence. In the case of Harvard University, it was true that by the time of its tercentenary (300th anniversary of its founding) in 1936, Harvard had already achieved a reputation as a world-class institution. Harvard did not have the stature that it does today.

As academics we have pretty good judgment about the quality of institutions that cannot simply be measured by counting the number of papers published or patents received. Outsiders who swoop in to count beans and make up lists based on statistics have little sense of what excellence is.

I suppose the situation varies from field to field. If you're a mathematician, your proficiency in English may not be such a problem. If you're in the humanities or social sciences, there is no doubt that it is a handicap for you.
