Our Sustainable Earth - Friday, October 7, 2011 - 11:30am - 12:30 pm  (Keynote speaker)

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

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.

*“We advocate that every student majoring in physics and/or astronomy engage in a meaningful undergraduate research experience.” For more detail, see http://www.spsnational.org/governance/statement /2008undergraduate_research.htm along with some background and history about this statement.


The APS Minority Bridge Program - Friday, October 7, 2011 - 9:10am - 9:35am

Dr. Theodore Hodapp,  Director of Education and Diversity for the American Physical Society (APS)

Hodapp Learn about Dr. Hodapp work here.

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

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

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

Kiang Dr. Kiang's Research Group is presented here.

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

  John Cotton       
Scarlise

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

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

Tribble A link to his university directory: click here

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

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.
