Harold Shapiro Presents EPP2010 Report
Particle physics is on the threshold of major scientific discoveries, but unless the United States takes prompt action, it risks being left out.
This was the message of Harold Shapiro, acclaimed economist and chairman of the National Academies Committee on Elementary Particle Physics in the 21st Century (EPP2010). "Particle physics is at a crossroads," he told a lecture audience of approximately 300 at the Panofsky Auditorium on Friday.
In his talk, Shapiro summed up the conclusions and recommendations of the EPP2010 committee, which was formed in 2004 to identify compelling questions in elementary particle physics and recommend a prioritized implementation plan to address them.
In its report titled "Revealing the Hidden Nature of Space and TimeCharting the Course for Elementary Particle Physics" released on April 26th in Washington, D.C., the committee unveiled a 15-year plan for the future of U.S. participation in particle physics.
The EPP2010 committee's unusual feature was that less than half its members were particle physiciststhe others were experts from a variety of other fields including genetics, aerospace engineering, and economics. The non-particle-physicists were initially skeptical of the value of investing in particle physics, Shapiro said. But by the end, he said, everyone was convinced of the intellectual vitality of the field and excited about its potential to advance the frontiers of science.
In order to remain a leading player in particle physics, the U.S. will have to invest a large amount of "risk
capital," Shapiro said. This capital would be needed to act on the following six priorities identified by the
Many U.S. experiments in particle physics are nearing the end of their life cycles, Shapiro said. Without a commitment from the government, the U.S. share in the field could decline to half its size in a decade. "The center of gravity will shift to Europe and Japan," Shapiro said.
Shapiro stressed the importance of strategic partnerships with other countries in future particle physics projects. He said that instead of asking foreign partners: "We are going to build this, will you help us?," we should ask: "What can we best build together?"
