What about brake fluid which is said to be incompressible. When I push down the brake pedal, the master cylindre pushes the brake liquid inside the hoses which tightens the brakes immediately? So what is the speed of propagation in this scenario if it cannot be faster than c even though brake fluid seems incompressible?
Professor Grosse Perdekamp received his diplom in physics from Freiburg University in 1990, and his Ph.D. in physics from the University of California, Los Angeles, in 1995. He was an associate research scientist at Yale University from 1995 to 1998, and a research scientist at Johannes Gutenberg University in Mainz, Germany, from 1998 to 1999. Most recently, he was a RIKEN Fellow at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) facility. He joined the Department of Physics at the University of Illinois as an assistant professor in 2002 remaining a Fellow at RIKEN through 2007.
Professor Grosse Perdekamp is a high-energy nuclear physics experimentalist who is a member of the PHENIX experiment at RHIC. The PHENIX collaboration, which includes 498 physicists and engineers from 70 institutions in 14 countries, engages in a broad program of studying QCD phenomena at RHIC, including the physics of heavy ion collisions, the spin-dependent structure of the proton in polarized proton-proton collisions, and the study of nucleon structure in a nuclear environment in proton- or deuteron-ion collisions.
He has taken a leadership role in PHENIX's spin-physics program, which will employ the polarization of the proton beams at the RHIC collider to perform spin-dependent measurements at the highest energy scales yet explored. Important components of his research interest are the study of transverse spin pheonomena and the preparation of spin physics program with W-boson at RHIC.
