Nov. 30, 2005 – As the 2005 World Year of Physics nears
its end, University of Utah physicists will deliver two free public
lectures billed as “An Evening with Einstein” on Tuesday
Dec. 6 and Wednesday Dec. 7 at Kingsbury Hall.
Benjamin Bromley, an associate professor of physics, will speak
on “Space, Time and the Expanding Universe” during
the 7 p.m. Tuesday Dec. 6 lecture.
“Albert Einstein’s ideas on space and time gave us
a new way to look at the universe,” according to a summary
for Bromley’s lecture. “His theory of gravity predicted
curved spacetime and black holes, with gravity so strong not even
light could escape. Einstein’s theory also enabled us to
build a picture of our Universe as it transformed from a hot Big
Bang into the web of galaxies we see today. However, this picture
also contains mysteries, for it suggests the presence of dark
matter surrounding galaxies, and dark energy, which seems to permeate
all of space.”
Orest Symko, a professor of physics, will discuss “The Quest
for Energy Using Heat and Sound” during the 7 p.m. Wednesday
Dec. 7 lecture.
“Since waste heat is around us, from large machines to microelectronics,
its conversion to electrical power can provide an important source
of renewable energy,” according to a summary of Symko’s
talk. “A new method of doing this will be presented. It
deals with the conversion of heat to sound and then directly to
electricity. In presenting this approach, fundamental questions
dealing with heat, engines, and acoustics will be covered with
demonstrations. The role of Brownian motion will be discussed.”
The two lectures are among the final events during the University
of Utah’s observance of the 2005 World Year of Physics,
which is a global celebration of the centennial of Albert Einstein’s
major discoveries in 1905. That was Einstein’s so-called
“miracle year” during which he published three fundamental
papers that laid the foundation for modern technology and for
relativity and scientific understanding of the universe.
The final University of Utah event planned for the World Year
of Physics will be the last screening in the Physics Film Festival.
That will occur from 7 p.m. to midnight on Saturday Dec. 17, when
the films “The Best Mind Since Einstein” and “Planet
of the Apes” will be shown in room 101 of the James Fletcher
Bldg. Admission is free of charge.
