    • Departmental Colloquium : Violent Events in Rocky Planetary Systems, Ben Zuckerman, Research Professor and Emeritus, UCLA

      When: Thursday, March 5, 2015 3:30 pm - 4:30 pm Where: Physics Auditorium (Rm. 202)

      Implications for the fate of technological civilizations, including our own

    • Special : Search For Extraterrestrial Intelligence and Why It Will Fail, Ben Zuckerman, Research Professor and Emeritus, UCLA

      When: Wednesday, March 4, 2015 7:00 pm - 8:00 pm Where: Physics Auditorium (Rm. 202)

      In recent years astronomers have discovered that essentially all stars are orbited by planets, thus raising the hopes of many persons that life and even technological life is common in our Milky Way galaxy and will soon be found.  Notwithstanding the existence of so many planets, we present reasons why technological life is a very rare phenomenon and thus will be very difficult to discover.

    • Departmental Colloquium : Computer Simulation Studies of Polymer Adsorption and Aggregation - From Flexible to Stiff, Prof. Wolfhard Janke, University of Leipzig

      When: Thursday, February 26, 2015 4:00 pm - 5:00 pm Where: Physics Auditorium (Rm. 202)

      An overview is given on recent computer simulation studies of polymer adsorption and aggregation using generic coarse-grained models. The simulations are performed with Monte Carlo methods in generalized ensembles (multicanonical and parallel tempering) and analyzed from a canonical and microcanonical view. As examples polymer chains interacting with a flat patterned surface or being confined in a spherical cage will be discussed. Of particular interest is the scaling behavior of conformational transitions in dependence of the polymer's bending stiffness. Bending stiffness also  plays a key role for semiflexible polymer aggregation. Our results show that this is the distinguishing parameter that controls whether amorphous aggregates or twisted bundle-like motifs are formed.

    • Departmental Colloquium : Research on Transfer and Implications for Learning and Problem Solving, Dr. Sanjay Rebello, Kansas State University

      When: Thursday, January 22, 2015 3:30 pm - 4:30 pm Where: Physics Auditorium (Rm. 202)

      Transfer of learning is often described as the overaching goal of education.  I will provide a broad overview how the theoretical perspectives on transfer of learning have evolved over time and delve deeper one perspective of transfer that has served as an overaching framework for some of the projects in our reasearch group over the past few years.  In particular I will discuss projects that utilize this perspective to facilitate problem solving. One of these projects focuses on facilitating transfer of mathematical integration to problem solving in a calculus-based physics course for future engineers. The other focuses on the use of visual cueing to facilitate learning and problem solving. I will discuss how these interdisciplinary efforts have advanced our knowledge of how students learn and solve problems in STEM disciplines.

    • Departmental Colloquium : Are the Parameters of the Standard Model fine-tuned for Carbon-based Life?, Prof. Dean Lee, NC State

      When: Thursday, December 4, 2014 3:30 pm - 4:30 pm Where: Physics Auditorium (Rm. 202)

      I discuss some recent results obtained using ab initio lattice simulations of effective field theory to probe nuclear structure. I present recent lattice calculations of the Hoyle state of 12C and whether or not light quark masses must be fine-tuned for the viability of carbon-based life.

    • Using Nanotechnology to Improve Treatment for Stroke Victims

      UGA Researchers including Physics Professor Yiping Zhao have developed a new technique to enhance stroke treatment using magnetically controlled nanomotors to transport a clot-busting drug to blockages in blood vessles. Results of this new technique are published in the Journal ACS Nano, and is featured in UGA's Research News. The clot-busting drug, recombinant tissue plasminogen activator, or t-PA is usually delivered to blood clots intraveneously.  In the UGA Research story, Dr. Zhao explains that “Our technology uses magnetic nanorods that, when injected into the bloodstream and activated with rotating magnets, act like stirring bars to drive t-PA to the site of the clot. Our preliminary results show that the breakdown of clots can be enhanced up to twofold compared to treatment with t-PA alone.” You can read more about this potentially life-saving research in the UGA Research Blog.

    • Physicist John Campbell to give Fire-Walking Lecture and Demonstration

      Dr. John Campbell, a retired physicist from the University of Canterbury in Christchurch, New Zealand, will offer a fire-walking demonstration in the quad adjacent to the physics building following a lecture on the subject on Thursday, Sept. 19, 2013. The lecture will be held at 7:00 pm in the Physics Auditorium (rm 202), and the demonstration will be in the physics quad immediately following the lecture. Both the lecture and demonstration are free and open to the public. 

      Campbell plans to discuss the reasons why anyone can fire walk and what the rules are, then invite those in attendance to give it try. He has visited and presented fire-walking demonstrations in Athens twice previously, most recently in 2005.

    • Ying Wai Li is the recipient of two prestigious UGA Graduate Student awards in 2013

      • Graduate Student Excellence-in-Research Award, 2013
      Initiated in 1999 to recognize the quality and significance of graduate student scholarship, these awards may be given in five areas: Fine Arts, Humanities and Letters, Life Sciences, Mathematical and Physical Sciences, and  Applied Studies.

      • Robert C. Anderson Memorial Award, 2013
      This award is given to recent Ph.D.s for outstanding research at the University or immediately after graduating. It is named for the late Robert C. Anderson, who served as UGA’s vice president for research and president of the University of Georgia Research Foundation, Inc.

      Ying Wai Li, a doctoral graduate in physics, was an outstanding graduate student researcher while at UGA, and her many accomplishments led to her current postdoctoral fellowship at Oak Ridge National Laboratory. For her PhD research project, Li worked at the interface between physics, computational science and biochemistry. She carried out very detailed simulations of the hydrophobic-polar protein folding model, which examines how proteins become functional in space. Her painstaking work led to the identification of a small number of “universal classes” of protein folding behavior. Understanding the folding behavior of proteins under diverse conditions is key to interpreting their functional properties, and Li developed a number of novel approaches to speed up the simulations and to permit her to access system sizes necessary to reveal the relevant physics. Her work explores and maps new territory, and the conclusions she has drawn may lead to new design principles for proteins or peptides used in nanotechnology and a range of real-world applications.
