The Mystery of Dark Energy and the Accelerating Universe
An Undergraduate Lunch with
Adam Riess, 2011 Nobel Laureate in Physics
The Twenty-third Konopinski Memorial Lecturer in
Wednesday, March 20, 12:30-2 p.m.
Harlos House (1331 E. Tenth St.)
SIGN-UP REQUIRED: See details below.
Physicists concluded that with the "Big Bang" 13.7 billion years ago the
universe began expanding and was continuing to do so although at a
slower rate in recent times. In the late 1990s, contrary to current
theory, Adam Riess and Brian Schmidt leading one group and Saul
Perlmutter leading a competing group made a fascinating, unexpected, and
still puzzling discovery that won them the 2011 Nobel Prize in Physics:
The expansion of the universe is speeding up! Other groups have since
confirmed their measurements and their discovery that some mysterious
new process is causing galaxies to recede from one another at an
increasing rate. Although the exact cause is not known, astrophysicists
have given it a name"dark energy."
Join Adam Riess for lunch and an informal conversation that can
range as widely as you would like, from the mysteries of "dark energy"
to other interesting issues in science and science policy.
Riess is the Thomas J. Barber Professor in Space Studies at
Johns Hopkins University, a Distinguished Astronomer and senior member
of the science staff at the Space Telescope Science Institute, and a
member of the National Academy of Sciences. His many awards include the
Albert Einstein Medal, the MacArthur "genius" grant, the Shaw Prize in
Astronomy, and the Gruber Cosmology Prize (shared).
SIGN-UP INFO: If you are interested in attending this
undergraduate lunch, please e-mail Anna Duquaine (firstname.lastname@example.org),
you wish to sign up for the "Riess" lunch and include your name,
e-mail address, year in school, and field(s) of study. This program is
open to any IU undergraduate through this sign-up process; but space
is limited so we will let you know by e-mail if a space was available
when you replied. The lunch is co-sponsored by the Hutton Honors
College and the Wells Scholars Program.
Riess will deliver the Joseph and Sophia
Konopinski annual public lecture in physics and astronomy on
"Supernovae and the Discovery of the Accelerating Universe" on
March 19, 7:30 p.m. in Whittenberger Auditorium in the IU Memorial
