Recent evidence demonstrates that the earth
has been warming monotonically since 1980.
Transient to equilibrium temperatures takes
centuries to develop, as oceans are slow to
respond to atmospheric temperature changes.
Atmospheric CO2 concentrations, from ice core and
observatory measurements, display consistent
increases from historical averages, beginning
about 1880, and can be associated with the
industrial revolution. The climactic
consequences of this human dominated increase in
atmospheric CO2 define a geologic epoch that has
been termed the “Anthropocene.” The issue is
whether this is a short term, relatively minor
change in global climate, or an extreme deviation
that lasts for thousands of years. Eight
“myths” that posit the former are examined in
light of known data. The analysis strongly
suggests the latter. In order to stabilize
global temperatures, sharp reductions in CO2
emissions are required, of the order of 80%.
Two examples of economically sustainable CO2
emission reduction demonstrate that technological
innovation has the potential to maintain our
standard of living while stabilizing global
temperatures.
Great
Time to Do Physics
- Friday, October 7, 2011 - 8:20am
- 9:10am
Dr. Gary
White, Director, Society of Physics Students
and Sigma Pi Sigma
Associate Director of Education, American Institute
of Physics, gwhite@aip.org
Has there ever been a more
exciting time to do physics? Whether you're interested in the
big philosophical questions of matter and energy or just the next cool
wireless gadget, in saving the world from nuclear annihilation or
saving a single life with positron emission tomography,
physics is a great place to begin the journey. In this
talk, I'll expound a bit on career trajectories of
hidden physicists, and touch on tales from a
variety of physics research topics, from spintronics
to
spallation to spandex. Yes, it is an unlikely trio,
but within each are opportunities for "a meaningful
undergraduate research experience”, the kind advocated
by the SPS Council for all undergraduate
physics majors*. Along the way, I'll mention some
pointers for physics undergraduates about
preparing for their future, whether it includes
summer
research internships, industry aspirations, or
graduate school.
Physics has one of the lowest participation rates for
underrepresented minorities and women of all Science,
Technology, Engineering and Mathematics (STEM)
fields. Things are improving for women and while
still not representative of the population, the trends
have been encouraging. Underrepresented
minorities, however, have not been as fortunate. I
will describe the current status of participation in
physics, and a new program being launched by the
American Physical Society that aims to significantly
increase the number of minorities who receive PhDs in
physics. The Minority Bridge Program is bringing
together representatives from doctoral granting
institutions and universities that educate minority
students to establish a set of model programs based on
the successes of existing efforts and capitalizing on
the strengths of the American Physical Society.
Our goal is to improve graduate education for all
students by improving the opportunities for minority
students.
Building sustainable systems that support success of
underrepresented students - Friday, October 7, 2011 - 9:35am -
10:00 am
Dr. Eric Brewe,
Florida International University; Assistant Professor,
Department of Teaching and Learning & Physics
Department
The number of physics
majors at Florida International University has grown
from 37 declared majors in 2003 to 143 in 2011. This
growth provides us with an opportunity to investigate
the components of FIU's educational system which have
contributed to this growth and the overall success of
our students at FIU. Understanding student success at
FIU is important because FIU is a research intensive
Hispanic Serving Institution which has a majority of
students who have been historically underrepresented
in physics including, minority students and women. Our
primary efforts have focused on developing supportive
learning environments through the implementation of
Modeling Instruction in several sections of
introductory physics and providing dedicated space for
student collaboration outside of class. We provide
data indicating that the Modeling courses support
enhanced learning, attitudes, and retention and that
the space is being utilized by students to integrate
into the physics department.
Why is the expansion of
the universe accelerating? - Friday October 7, 2011
- 5:15pm - 6:05 pm
Dr. Mustapha
Ishak-Boushaki, Associate Professor, Head
of the Cosmology Group, University of Texas at
Dallas
For more than a
decade, a number of cosmological observations have
been indicating that the expansion of the universe
is accelerating. Cosmic acceleration and the
questions associated with it have become one of the
most challenging and puzzling problems in cosmology
and physics. Cosmic acceleration can be caused by
(i) a repulsive dark energy pervading the universe,
(ii) an extension to General Relativity that takes
effect at cosmological scales of distance, or (iii)
the acceleration may be an apparent effect due to
the fact that the expansion rate of space-time is
uneven from one region to another in the universe. I
will review the basics of these possibilities and
provide some recent results on these questions.
Single Molecule Manipulation - Friday October 7, 2011 -
2:35pm - 3:25 pm
Dr. Ching-Hwa Kiang,
Associate Professor, Rice University - Houston
Single-molecule
manipulation studies open a door for a close-up
investigation of complex biological interactions at
the molecular level. In these studies, single biomolecules
are pulled while their force response is being
monitored. The process is often nonequilibrium,
and interpretation
of the results has been challenging. We used the
atomic force
microscope to pull proteins and DNA, and determined
the equilibrium properties of the molecules using the recently
derived nonequilibrium work theorem. I will present
applications of the technique in areas ranging from fundamental biological
problems such as DNA mechanics, to complex medical processes such as
the mechanical activation of von Willebrand Factor, a key protein in
blood coagulation.
Banquet Talk
The Scientific Method - Critical and Creative
Thinking - Friday, October 7, 2011 - 8:30 pm
- 9:30 pm
Dr. John Cotton and
Dr. Randall Scarlise, Department of Physics,
Southern Methodist Universty, Dallas
The “scientific method” is not just for
scientists! Combined with critical thinking, the
scientific method can enable students to distinguish
credible sources of information from nonsense and
become intelligent consumers of information.
Professors John Cotton and Randall Scalise illustrate
these principles using a series of examples and
demonstrations that is enlightening, educational, and
entertaining. This lecture/demonstration features
highlights from their course (whose unofficial title
is “debunking pseudoscience” ) which enables students
to detect pseudoscience in its many guises: paranormal
phenomena, free-energy devices, alternative medicine,
and many others.
Crisis in Texas Higher Education: The Need for
Leadership -
Friday, October 7, 2011 - 9:35am - 10:00 am
Dr. Richard Tapia,
Director,
Center for Excellence and Equity in Education,
Department of Computational and Applied Mathematics
(CAAM), Rice University Dr. Tapia will receive the National Medal of
Science from President Obama, the highest scientific
award in the US.Rice University press
release.
Texas has the fastest
growing Hispanic population in the nation. Hispanics
will soon comprise a majority of the state’s
population. Yet this population has a high school
drop-out rate of nearly 60% and is vastly
underrepresented in STEM (science, technology,
engineering, and mathematics) disciplines in the
student bodies and faculties of the state’s
universities. The scientific and economic health of
the state is threatened with the formation of such a
large scientific underclass. But Rice is making a
difference, positioning its underrepresented minority
students for STEM leadership throughout the state and
nation. The speaker will discuss several successful
national award-winning undergraduate and graduate
programs that he directs at Rice University that are
being heralded as models for the state, region, and
nation.
The World-Wide Effort to Understand the
Visible Matter in Our Universe -
Saturday, October 8, 2011 - 8:30am -
9:20am Dr. Robert E. Tribble,
Distinguished Professor of Physics & Astronomy,
Texas A&M University - Cyclotron Laboratory
Director
A general goal in nuclear physics is to explain the
origin, evolution, and structure of the visible matter
in the universe. Today, nuclear physicists are
working at a wide range of facilities around the world
to provide information to help guide us to an
understanding of this issue. I will provide a
general overview of the field, which will focus on the
important questions that are being addressed, the
facilities that are being used to answer them, and a
roadmap of the new construction projects that will
define the field in the next decade.
All
things White Dwarf: The State of Stellar Forensics
at the University of Texas and Sandia National
Laboratories - Saturday, October 8,
2011 - 11:20am - 12:10
Dr. Donal Winget,
Harlan J. Smith Centennial Professor in Astronomy,
University Distinguished Teaching Professor, University
of Texas at Austin
Astronomy has always been considered an
observational science, in contrast with other
experimental sciences like physics, chemistry, biology, and geology. This is because
it has not been possible to perform experiments
on the objects
we observe. This situation has changed in a way that
is transformational.
We are now able to make macroscopic bits of star
stuff in
the lab: plasmas created underconditions that are the
same as the plasmas in stars. Although laboratory
astrophysics has long been an important part of
astronomical research, what has changed is the
ability to produce large enough chunks of a star that we
can make measurements and perform experiments.
In this way, astronomy joins her sister sciences in becoming an
experimental science as well as an observational
one. I will
describe how this came about, the technology behind
it, and the results of recent laboratory experiments.
Most importantly, we will discuss how this will
change our understanding of the universe and its
contents.
This work will shed new light on our recent
discoveries involving McDonald Observatory: planets
around white dwarf stars, massive carbon/oxygen
variable white dwarf stars, and white
dwarf-white dwarf binaries -- including one detached
double eclipsing system with an orbital period of 12
minutes, We should measure the rate of change
of the
orbital period in this system within a year and we
expect it to be the highest S/N source of gravitational
radiation, easily detectable with LISA or similar
approaches.
