What struck me was some regularity in the anomaly. The rotational velocities were not just larger than expected, they became constant with radius. Why? Sure, if there was dark matter, the speed of stars would be greater, but the rotation curves, meaning the rotational speed drawn as a function of the radius, could still go up and down depending on its distribution. But they didn't. That really struck me as odd. So, in 1980, I went on my Sabbatical in the Institute for Advance Studies in Princeton with the following hunch: If the rotational speeds are constant, then perhaps we're looking at a new law of nature. If Newtonian physics can't predict the fixed curves, perhaps we should fix Newton, instead of making up a whole new class of matter just to fit our measurements.

A similar situation occurred in astronomy, where the Newtonian law of gravitation had been found to predict the orbits of the outer planets with great accuracy, but had failed with the orbits of Mercury and Venus. The relativity theory of gravitation had provided the necessary modification of Newton's law, and in working out the details of the new theory, Einstein had utilized the fact that Newtonian law gave the right result at great distances from the sun. Heisenberg, confronted with a similar problem, was able to avail himself of the fact that the classical mechanics gave the right result at great distances from the atomic nucleus. Here, and here alone Heisenberg's theory made contact with the world of the older physics.

By the end of the decade it had become obvious that perhaps the one constant of our variegated and strung-out peer groups was a pervasive sense of self-consciousness that sent us in grouchy packs to ugly festivals just to be together and dig ourselves and each other, as if all of this meant something greater than that we were kids who liked rock 'n' roll and came out to have a good time, as if our very styles and trappings and drugs and jargon could be in themselves political statements for any longer than about fifteen stoned seconds, even a threat to the Mother Country! So we loved and loved and doted on ourselves and our reflections in each other even as the whole thing got out of hand and turned into mud and disaster areas and downs and death.

Hadiya Pendleton was me and I was her, but I got to grow up and go to Princeton and Harvard Law School and have a career and a family and the most blessed life I could ever imagine. And Hadiya, we know that story. Just a week after she performed at my husband's inauguration, she went to a park with some friends and got shot in the back because some kid thought she was in a gang. Hadiya's family did everything right, but she still didn't have a chance. And that story, the story of Hadiya's life and death, we read that story day after day, month after month, year after year, in this city and around this country. So I'm not talking about something happening in a war zone, halfway around the world. I am talking about what is happening in the city that we call home.

As late as 1959, a friend and colleague of Albert Schweitzer defended his unsterile hospital in the following terms: Now to the domestic animals at the Hospital. People have been shocked by the informality with which animals and people mix, and although it is perhaps not always defensible on hygienic grounds, the mixture adds considerably to the charm of the place. The writer was a dental surgeon from New York, who would obviously have had a fit if a goat or chicken had wandered into his New York surgery. He knew full well that at Schweitzer's hospital "the goats, dogs and cats visit hospital wards teeming with microbial life of the most horrifying varieties,” but he defended their habitation with Africans because that was part of the culture and charm that had to be preserved!

There is an enormous difference between modern science and Greek philosophy, and that is just the empiristic attitude... Since the time of Galileo and Newton, modern science has been based upon a detailed study of nature and upon the postulate that only such statements should be made, as have been verified or at least can be verified by experiment. The idea that one can single out some events from nature by an experiment... to find out what is the constant law in the continuous change, did not occur to the Greek philosophers. Therefore, modern science has from its beginning stood on a much more modest, but at the same time much firmer, basis than ancient philosophy. Therefore, the statements of modern physics are in some way meant much more seriously than the statements of Greek philosophy.
