Laszlo Mihaly: Why do you need Einstein's special and general relativity to find your way in NYC?
The Global Positioning System (GPS) has transformed the way we travel. We discuss how the system was developed and what the basic principles are behind it. It turns out that without properly implementing time corrections predicted by Einstein's special and general relativity the system would not work.
Professor Mihaly is a condensed matter physicist and former Chair of the Department of Physics and Astronomy.
Salvatore Fazio: A New Particle Collide to Explore the Wonderful and Dynamical Inner Microcosm of the Visible Matter
An Electron-Ion Collider facility (EIC), a major new research facility to advance the long-term vision for Nuclear Physics in the United States, is under consideration at the Brookhaven National Laboratory (BNL) in Long Island. An EIC is designed to collide an electron beam with the currently existing RHIC hadron beam (protons and nuclei), capable of largely varying the energy produced in the collision and the species of nuclei accelerated. This new particle collider will be the ideal "microscope" for investigating, with an unprecedented precision, the three-dimensional picture of the internal structure of protons and nuclei. I will highlight the large impact that such machine can have versus the current knowledge of quarks and gluons (the building blocks of the visible matter) and thus how they contribute to all the basic properties that characterize a single nucleon, such as mass, charge and spin. An EIC will investigate the depths of the matter with an unprecedented precision and accuracy. It will open a new window though which we can gaze onto the universe around us and the matter inside us. It will be a world-class research facility, a prime source of knowledge and applications.
Dr. Fazio is a research scientist at the STAR experiment, installed at the Relativistic Heavy-Ion Collider (RHIC), at
Brookhaven National Laboratory. He works on the study the formation and characteristics of the quark-gluon plasma
(QGP), a deconfined state of matter that is believed to exist at an energy density sufficiently high. Its understanding will
provide information on the evolution the universe in its first moments of life immediately after the Big Bang. He
received his Ph.D. at the University of Calabria in 2007. Before coming to BNL he worked at the ZEUS experiment at the
HERA accelerator (DESY Lab, Hamburg, Germany) and at the ATLAS experiment at the LHC accelerator (CERN Lab, Geneva, CH).
