for all sensible quantum field theories, except for Yang-Mills-type gauge theories. Gross now took on a new graduate student, twenty-one-year-old Frank Wilczek, who had come to Princeton from the University of Chi- cago planning to study mathematics, but who switched to physics after taking Gross's graduate

her lucky or astute because he served as the graduate supervisor of probably the two most remarkable intellects among physi- cists in my generation, Wilczek and Edward Witten, who helped lead the string theory revolution in the 198os and '9os and who is the only physicist ever to win the prestigious Fie

political machinations eventually led to SSC's demise in October 1993. I remember the time well. I had recently moved from Yale to be- come chair of the Physics Department at Case Western Reserve Uni- versity, with a mandate to rebuild the department and hire twelve new faculty members over five years. The first year w

Along with Frank Wilczek, I wrote a paper that not only pointed out that such an observation would indicate a symmetry-breaking scale that corresponded nicely to the Grand

M. Krauss is director of the Origins Project at Arizona State University and Foundation Professor in the School of Earth and Space Exploration and the Physics Department there. Krauss is an internation- ally known theoretical physicist with wide research interests, including the interface between elementary-particle

Some examples of brandied Hamiltonians were explored both classically and in the context of quan- tum mechanics, as recently advocated by Shapere and Wilczek. These are in fact cases of switch- back potentials, albeit in momentum space, as previously analyzed by us for quasi-Hamiltonian chaotic dynamical

While the Physics Department has consistently supported our research efforts during the last three decades, additional outside support is critically needed for us to carry out
