Renaissance Physicists This duet of talks by two Nobelists, while cheering the consolidation of MIT’s Physics groups within the new Green Center for Physics, sees primarily gloomy prospects for science in coming decades. There are “dark clouds on the horizon,” believes Robert Laughlin, as the post-World War 2 public funding of basic research dwindles. In its wake, commercial interests are gaining control over the production of knowledge, favoring chemistry, materials sciences and engineering disciplines. In a technical milieu, some of the people “have to have a wild childlike curiosity where they demand to understand everything,” and this “omnivorous” person is typically a physicist, says Laughlin. Omnivorous scientists are not valuable to industry, and often dangerous, since they make knowledge public rather than hiding (or patenting) it. But university students and their parents need such teachers, who provide an invaluable balance to the relentless forces in the world driving technical knowledge into corporate realms. The “era we’re in right now is an era of darkness in which the entire idea of public domain knowledge is being rejected by people very high up in society, and implemented in laws,” says Laughlin. So the young physicist must regard himself “as a revolutionary person… a troublemaker when it comes to the sequestration of knowledge.” Concludes Laughlin, “Our job is “to make sure the concept of reason, the science of reason, does not perish from the earth.” Learning from MIT Pulling people together across scientific boundaries has proven valuable in the past, and is even more essential moving forward, believes Steven Weinberg. In his own years at MIT, scientists banded together to oppose the deployment of an anti-ballistic missile system, and formed the Union of Concerned Scientists to help guide government science policy. Today, there’s an urgent need for a unified scientific voice to speak out on key issues. He singles out for derision NASA’s singl...
