T he Michelson Lecture Series, sponsored by the United States Naval Academy Class of 1969, commemorates the achievements of Albert A. Michelson, Naval Academy graduate Class of 1873 and instructor, and the first American scientist to receive a Nobel Prize. Each year since 1981, a distinguished scientist has come to the Naval Academy to present the Michelson Lecture. This year the Michelson Lecture is hosted by the Physics Department. The Class of 1969 is proud to sponsor this lecture by Professor and Nobel Laureate, Dr. Adam Riess, of Johns Hopkins University.

Barber Professor of Physics and Astronomy Krieger School of Arts and Sciences Johns Hopkins University Prelude U. S. Naval Academy Woodwind Quintet A dam Riess is the Thomas J. Barber Professor of Physics and Astronomy, Krieger-Eisenhower Professor of Physics and Astronomy at the Krieger School of Arts and Sciences, Johns Hopkins University, and a distinguished astronomer at the Space Telescope Science Institute. He is also a member of the National Academy of Sciences. He received his bachelor’s degree in physics from the Massachusetts Institute of Technology in 1992 and his Ph.D. from Harvard University in 1996. His research involves measurements of the cosmological framework with supernovae (exploding stars) and Cepheids (pulsating stars). Currently, he leads the SHOES Team in efforts to improve the measurement of the Hubble Constant and the Higher-z Team to find and measure the most distant type la supernovae known to probe the origin of cosmic acceleration. In 2011, he was named a co-winner of the Nobel Prize in Physics and was awarded the Albert Einstein Medal for his leadership in the High-z Supernova Search Team’s discovery that the expansion rate of the universe is accelerating, a phenomenon widely attributed to a mysterious, unexplained “dark energy” filling the universe. The discovery was named by Science magazine in 1998 as “the Breakthrough Discovery of the Year.” His accomplishments have been recognized with a number of other awards, including a John D. and Catherine T. MacArthur Foundation “Fellowship Grant” in 2008, the Gruber Foundation Cosmology Prize in 2007 (shared), and the Shaw Prize in Astronomy in 2006. History of the Michelson Memorial Lecture Andrew Phillips, Ph.D. Academic Dean and Provost Introduction of the Guest Speaker Captain John O’Neill, USN Director, Mathematics and Science Division Michelson Memorial Lecture Adam Riess, Ph.D. “Supernovae Reveal An Accelerating Universe” Question and Answer Session Dr. Riess Presentation to the Speaker Midshipman 1/C Eric Swanson, USN and Major Stephen W. Comiskey, USMCR (Ret.) President, USNA Class of 1969 Abstract: In 1929 Edwin Hubble discovered that our Universe is expanding. Eighty years later, the Space Telescope that bears his name is being used to study an even more surprising phenomenon: that the expansion is speeding up. The origin of this effect is not known, but is broadly attributed to a type of “dark energy” first posited to exist by Albert Einstein and now dominating the mass-energy budget of the Universe. Professor Riess will describe how his team discovered the acceleration of the Universe and why understanding the nature of dark energy presents one of the greatest remaining challenges in astrophysics and cosmology.
