Adam’s Demonstrations
SPECTRUM Volume 1, Issue 1 Summer 2009
Name change reflects evolution in curriculum, research and department as a whole.
S
peaking to students at the Spring 2009 Undergraduate Seminar, department Chairman Dave Kieda declared, “None of you here will ever receive a degree from the Department of Physics.” The room filled with shocked silence as Kieda continued, “The Department of Physics is officially the Department of Physics and Astronomy!” The change was approved by the Board of Regents on March 23 and was celebrated on June 3 in the James Fletcher Building. Physicists and astronomers alike came together over an assortment of space cake, Starbursts, Milky Way candy bars, and Starlight mints, to celebrate the landmark achievement. Kieda and Pierre Sokolsky, dean of the College of Science, both spoke briefly, highlighting the department achievements of the last year. Recognition was given to Zeke Dumke of the E.R. & E.W. Dave Kieda (right) after presenting a certificate of appreciation to Steve Denkers. Dumke Foundation, and to Steve Denkers of the Willard L. Eccles Foundation. Generous funding from both foundations have helped establish and develop the current astronomy program and its research. Astronomy courses were first taught on campus in the 1890s, as a part of the math department, and the university has had an on-campus observatory of one form or another for the last 50 years, but there was never a dedicated astronomy program until now. Within the department, astronomy research started with the discovery of a nova, by Professor Don Groom, and has continued for more than 35 years. For students, the department now offers a major degree program in Astronomy, and a minor as well. The title ‘Department of Physics’ is now a thing of the past. However, for the ‘Department of Physics and Astronomy’, when looking towards the future, the stars are the limit.
Adam’s Off-The-Wall Demos
New Faculty Join Physics & Astronomy Douglas Bergman
Adam Bolton
Douglas Bergman is interested in all aspects of ground based observations of cosmic rays. He is a member of the Telescope Array collaboration in Delta UT, seeking to measure the spectrum, composition of ultra-high energy cosmic rays and to determine their sources. This experiment detects the cosmic ray air showers both by collect the shower particles as they hit the ground and observing the fluorescence light emitted as they pass through the atmosphere. Prof. Bergman comes to Utah from Rutgers University in NJ, where he was an Assistant Professor, and prior to that a post-doctoral associate. He received his Ph.D. from Yale University in 1997, working on a fixed target, high energy physics experiment at Brookhaven National Lab. He enjoys most outdoor athletic activities including running, skiing, volleyball and soccer. Indoors, he likes all types of live musical performance.
Adam Bolton joins the department in August 2009. His interests are observational cosmology; formation, structure, and evolution of galaxies; and astronomical spectroscopy. He is a founding member of the Sloan Lens ACS (SLACS) Survey collaboration, which has combined SDSS spectra with Hubble Space Telescope images to nearly double the number of known “gravitational lens” galaxies. Dr. Bolton will continue his gravitational lensing research program, and will pursue extensive involvement in the SDSS3 and other massive astronomical spectroscopic surveys. He was employed as the Beatrice Watson Parrent Postdoctoral Fellow at the University of Hawaii, and was also a CfA Postdoctoral Fellow at the Harvard Smithsonian Center for Astrophysics. He obtained his Ph.D. in physics from MIT in 2005. His outside interests include cooking, music, and economics. He is looking forward to the skiing and hiking opportunities in Utah.
Shanti Deemyad
Inese Ivans
Starting January of 2010, Shanti Deemyad joins the University of Utah from Harvard University, where she completed her postdoc. She received her Ph.D from Washington University in St. Louis. Her main field of interest is condensed matter at extreme conditions. The research would be divided in two major areas; studying the nature of electronic interactions in existing solid state systems such as physics of quantum solids, the second being the synthesis of materials with new or enhanced properties for storage and transport of energy by guidance of high pressure studies. The unifying purpose is to find and explore new exotic states of matter which have strong promises for material engineering. Shanti enjoys a wide variety of activities. She loves stargazing and visiting archeological sites. She loves the mountains and the outdoors. Among other activities she enjoy playing chess, watching Sci-Fi movies and reading books. Her favorite authors are Kundera, Kafka, Hesse and Camus.
Inese Ivans is an observational astronomer. She specializes in the application of stellar spectroscopic tools to investigate topics ranging from the origins of chemical elements in the Universe to the formation and evolution of galaxies, including our own Milky Way. She is interested in developing astronomical applications to exploit large data sets such as the Sloan Digital Sky Survey using statistical, data mining, and scientific visualization techniques. She joins the University of Utah in August of this year from Princeton University, where she most recently has held a joint postdoctoral fellowship with the Observatories of the Carnegie Institution for Science. Previously Inese was on a fellowship at the California Institute of Technology, moving there from the University of Texas at Austin where she received her Ph.D. Her undergraduate work at the University of Toronto introduced her to astronomical research, something she is keen to continue here.

Michael Vershinin
Assistant Professor vershinin@physics.utah.edu
Dr. Michael Vershinin will start in January 2010 as the first professor in the new BioPhys research program in the department. He has a Bachelor degree in Engineering from Cooper Union, a PhD in Physics from University of Illinois at Urbana-Champaign, and additional biologyrelated training from his postdoctoral work at UC: Irvine. His research interests are similarly interdisciplinary and reside at the interface of biology, physics, mathematics, and computer science. Michael is using techniques such as optical trapping to investigate the function of single molecules and molecular complexes. He is also developing methods for better quantifying and modeling biological processes. His current focus is on molecular motors – how things are transported inside of cells, how this transport is regulated and routed and ultimately how it can break down. The latter question is important for understanding many types of cell degeneration and the related diseases (e.g. Alzheimer’s disease and similar dementias).
In each newsletter, Adam Beehler, Lecture Demonstration Specialist, explains one of his demonstrations. This demo won second place at the American Association of Physics Teachers 2009 Summer Meeting in Ann Arbor, MI.

Simple Photoelectric Effect When ultraviolet light, x-rays, or other forms of electromagnetic radiation are shined on certain kinds of matter, electrons can be ejected. This phenomenon is known as the photoelectric effect. It made scientists think about light and other forms of electromagnetic radiation in a whole new way. The peculiar thing about the photoelectric effect is the relationship between the frequency (energy) of the light shined on a piece of metal and the number of electrons ejected. The higher the frequency (energy) of the light source, the more electrons and thus electric current, is given off. Just making the same type of light brighter, or more intense, does not give the ejected electrons any more energy. Demo Albert Einstein’s Nobel Prize winning photoelectric effect has been demonstrated for many years quite effectively, yet now it can be done with simple household items. Past versions used specialized black lights or carbon-arc lamps to show any effect. This version takes advantage of the currently popular germ sanitizer lights, which are much more affordable and portable. It also uses aluminum pop cans instead of zinc plates and Christmas tree tinsel instead of standard electroscopes. Use • Lightly sand one side of your aluminum soda pop can to remove any oxidation/ outer coating. • Rub the PVC pipe with the brown paper. • Slide the pipe across the tinsel. The tinsel should now be negative and the strands repel from each other. • With the tinsel repelling, touch the soda pop can and discharge it. The tinsel should relax. If incoming light has enough energy, electrons will be • Charge the tinsel again with the negatively charged PVC pipe. ejected from the middle. • Move the UV germ sanitizer lamp into position (near, but not touching, the sanded portion of the soda pop can). Nothing should happen. • Turn it on and watch the tinsel slowly relax as the negative charges leave the aluminum. This is the photoelectric effect. The energy of the short-wave UV light is enough to eject electrons from the surface of the aluminum. • Charge the tinsel again with the negatively charged PVC pipe. • This time shield the soda pop can from the UV light with a piece of glass. Nothing should happen. The tinsel should remain charged. Why? The UV light is absorbed (or blocked) by the glass. Now remove the glass and watch the tinsel relax. • Charge the tinsel again with the negatively charged PVC pipe. • This time use the long-wave UV lamp. Nothing should happen. Why? This UV light does not have enough energy (too low a frequency) to eject electrons. • Charge the tinsel again but this time by induction so that the tinsel becomes positive. • Shine the short-wave UV lamp onto the soda pop can. Nothing should happen. Why? The photoelectric effect ejects electrons from the aluminum, and the tinsel and soda pop can already have a deficiency of electrons.

Growing An Astronomy Program at the University
Physics & Astronomy Renovating Despite Economy
208 South Physics Building
South Loading Dock
Equipment Lift- B39 James Fletcher Building
The Physics & Astronomy department began its first major renovation in a decade, in the spring of 2009. The initial construction began with the Intermountain Network Scientific Computation Center (INSCC). The summer semester saw a decline in students, and thus work increased to include areas of the South Physics and James Fletcher buildings. The initial focus of the million-dollar renovation is to provide space to accommodate the new Astronomy program including seven new Faculty offices, five new Research Labs, and many new and remodeled student areas and offices. Despite recent budget cuts this year and next, the renovations are necessary to accommodate the growth in the department. The commitments were made to expand the faculty and the accommodations are necessary, regardless of the timing. “ This is really an investment, not only in the department, but also in the future of the Astronomy program itself ”, Building Supervisor Harold Simpson said. “ The University is struggling some, but thanks to strong financial management, steady enrollment, and research funding, the blow is not as bad as it could have been and I think the University is definitely steadying itself.” Harold also mentioned that most of the contractors the university has awarded construction bids to, are local businesses, hiring local subcontractors. It is important to the university and the Physics and Astronomy Department especially, to keep work in the Salt Lake area and contribute to the local economy. Over the past 6 months, Harold Simpson has worked closely with architects to develop a master plan for department renovations. “ The architect conducted a study of the department facilities and operations in spring of 2008. The results were presented last summer and the renovation project was approved in September of 2008. The bid was awarded in late April and work began in May,” said Harold. While the current renovations satisfy present space needs, the department is looking toward the future and methods of accommodating growth. The long term space needs would require a new building with more lecture halls and a possible planetarium. While currently an unfunded project, the current renovations will be a considerable improvement. Areas of the buildings and certain rooms have been blocked off, some permanently, during the renovation. Many faculty and graduate students and a few undergraduate majors remain on campus. Other than the inconveniences of a few faculty offices moving from the James Fletcher building to INSCC, the minor interruption in South Physics while the floors were re -tiled, and a week long closure of the stockroom, the department continues to proceed as normal. Harold wishes to thank everyone for their cooperation and support. “In my hectic days, it may not be apparent; but I really do realize how this project impacts everyone. I will try to minimize the disruptions and inconveniences, but I must keep things moving forward.”

In the last few years, the Department of Physics & Astronomy has worked to grow an astronomy program with the support of the Willard L. Eccles Charitable Foundation. The department added an astronomy minor program, and used an $88,000 Eccles grant to refurbish an observatory atop the South Physics Building. The foundation also has provided $680,000 for the university to build an $800,000 observatory at 9,000 feet on Frisco Peak west of Milford, Utah. The university now is seeking approvals from the U.S. Bureau of Land Management and Beaver County. Dave Kieda says the 32-inch research-grade reflecting telescope now is being fabricated by DFN Engineering in Boulder, Colo. Observatory construction [started fall 2008] and the telescope’s “first light” is set for September 2009. Stephen Eccles Denkers, executive director of the Willard L. Eccles Charitable Foundation, says his family is “incredibly excited” to be involved in “elevating the University of Utah to one of the premier physics and astronomy departments.” With a $450,000 Eccles grant and a matching amount [from the office of David Pershing, the university ’s senior vice president for academic affairs], the Department of Physics & Astronomy is joining the third phase of the Sloan Digital Sky Survey (SDSS-III), an effort by about 20 research institutions around the world. Denkers says his mother, sister and cousins are enthusiastic about funding the U’s entry into the Sky Survey in part because they “would love to see more women get into the sciences, into physics and astronomy.” “Joining a recognized astronomy project like SDSS-III is a stepping stone to a successful astronomy program at the University of Utah,” says Paolo Gondolo, leader of the university ’s astronomy initiative and an associate professor of physics. “ The wide scope of the SDSS-III program - from planet searches to galactic studies to cosmology - offers ample choices of research topics to faculty and students.”

Adam Bolton
Douglas Bergman is interested in all aspects of ground based observations of cosmic rays. He is a member of the Telescope Array collaboration in Delta UT, seeking to measure the spectrum, composition of ultra-high energy cosmic rays and to determine their sources. This experiment detects the cosmic ray air showers both by collect the shower particles as they hit the ground and observing the fluorescence light emitted as they pass through the atmosphere. Prof. Bergman comes to Utah from Rutgers University in NJ, where he was an Assistant Professor, and prior to that a post-doctoral associate. He received his Ph.D. from Yale University in 1997, working on a fixed target, high energy physics experiment at Brookhaven National Lab. He enjoys most outdoor athletic activities including running, skiing, volleyball and soccer. Indoors, he likes all types of live musical performance.
Adam Bolton joins the department in August 2009. His interests are observational cosmology; formation, structure, and evolution of galaxies; and astronomical spectroscopy. He is a founding member of the Sloan Lens ACS (SLACS) Survey collaboration, which has combined SDSS spectra with Hubble Space Telescope images to nearly double the number of known “gravitational lens” galaxies. Dr. Bolton will continue his gravitational lensing research program, and will pursue extensive involvement in the SDSS3 and other massive astronomical spectroscopic surveys. He was employed as the Beatrice Watson Parrent Postdoctoral Fellow at the University of Hawaii, and was also a CfA Postdoctoral Fellow at the Harvard Smithsonian Center for Astrophysics. He obtained his Ph.D. in physics from MIT in 2005. His outside interests include cooking, music, and economics. He is looking forward to the skiing and hiking opportunities in Utah.
Shanti Deemyad
Inese Ivans
Starting January of 2010, Shanti Deemyad joins the University of Utah from Harvard University, where she completed her postdoc. She received her Ph.D from Washington University in St. Louis. Her main field of interest is condensed matter at extreme conditions. The research would be divided in two major areas; studying the nature of electronic interactions in existing solid state systems such as physics of quantum solids, the second being the synthesis of materials with new or enhanced properties for storage and transport of energy by guidance of high pressure studies. The unifying purpose is to find and explore new exotic states of matter which have strong promises for material engineering. Shanti enjoys a wide variety of activities. She loves stargazing and visiting archeological sites. She loves the mountains and the outdoors. Among other activities she enjoy playing chess, watching Sci-Fi movies and reading books. Her favorite authors are Kundera, Kafka, Hesse and Camus.
Inese Ivans is an observational astronomer. She specializes in the application of stellar spectroscopic tools to investigate topics ranging from the origins of chemical elements in the Universe to the formation and evolution of galaxies, including our own Milky Way. She is interested in developing astronomical applications to exploit large data sets such as the Sloan Digital Sky Survey using statistical, data mining, and scientific visualization techniques. She joins the University of Utah in August of this year from Princeton University, where she most recently has held a joint postdoctoral fellowship with the Observatories of the Carnegie Institution for Science. Previously Inese was on a fellowship at the California Institute of Technology, moving there from the University of Texas at Austin where she received her Ph.D. Her undergraduate work at the University of Toronto introduced her to astronomical research, something she is keen to continue here.

Michael Vershinin
Assistant Professor vershinin@physics.utah.edu
Dr. Michael Vershinin will start in January 2010 as the first professor in the new BioPhys research program in the department. He has a Bachelor degree in Engineering from Cooper Union, a PhD in Physics from University of Illinois at Urbana-Champaign, and additional biologyrelated training from his postdoctoral work at UC: Irvine. His research interests are similarly interdisciplinary and reside at the interface of biology, physics, mathematics, and computer science. Michael is using techniques such as optical trapping to investigate the function of single molecules and molecular complexes. He is also developing methods for better quantifying and modeling biological processes. His current focus is on molecular motors – how things are transported inside of cells, how this transport is regulated and routed and ultimately how it can break down. The latter question is important for understanding many types of cell degeneration and the related diseases (e.g. Alzheimer’s disease and similar dementias).

Simple Photoelectric Effect When ultraviolet light, x-rays, or other forms of electromagnetic radiation are shined on certain kinds of matter, electrons can be ejected. This phenomenon is known as the photoelectric effect. It made scientists think about light and other forms of electromagnetic radiation in a whole new way. The peculiar thing about the photoelectric effect is the relationship between the frequency (energy) of the light shined on a piece of metal and the number of electrons ejected. The higher the frequency (energy) of the light source, the more electrons and thus electric current, is given off. Just making the same type of light brighter, or more intense, does not give the ejected electrons any more energy. Demo Albert Einstein’s Nobel Prize winning photoelectric effect has been demonstrated for many years quite effectively, yet now it can be done with simple household items. Past versions used specialized black lights or carbon-arc lamps to show any effect. This version takes advantage of the currently popular germ sanitizer lights, which are much more affordable and portable. It also uses aluminum pop cans instead of zinc plates and Christmas tree tinsel instead of standard electroscopes. Use • Lightly sand one side of your aluminum soda pop can to remove any oxidation/ outer coating. • Rub the PVC pipe with the brown paper. • Slide the pipe across the tinsel. The tinsel should now be negative and the strands repel from each other. • With the tinsel repelling, touch the soda pop can and discharge it. The tinsel should relax. If incoming light has enough energy, electrons will be • Charge the tinsel again with the negatively charged PVC pipe. ejected from the middle. • Move the UV germ sanitizer lamp into position (near, but not touching, the sanded portion of the soda pop can). Nothing should happen. • Turn it on and watch the tinsel slowly relax as the negative charges leave the aluminum. This is the photoelectric effect. The energy of the short-wave UV light is enough to eject electrons from the surface of the aluminum. • Charge the tinsel again with the negatively charged PVC pipe. • This time shield the soda pop can from the UV light with a piece of glass. Nothing should happen. The tinsel should remain charged. Why? The UV light is absorbed (or blocked) by the glass. Now remove the glass and watch the tinsel relax. • Charge the tinsel again with the negatively charged PVC pipe. • This time use the long-wave UV lamp. Nothing should happen. Why? This UV light does not have enough energy (too low a frequency) to eject electrons. • Charge the tinsel again but this time by induction so that the tinsel becomes positive. • Shine the short-wave UV lamp onto the soda pop can. Nothing should happen. Why? The photoelectric effect ejects electrons from the aluminum, and the tinsel and soda pop can already have a deficiency of electrons.

SPECTRUM Volume 1, Issue 1 Summer 2009
Name change reflects evolution in curriculum, research and department as a whole.
S
peaking to students at the Spring 2009 Undergraduate Seminar, department Chairman Dave Kieda declared, “None of you here will ever receive a degree from the Department of Physics.” The room filled with shocked silence as Kieda continued, “The Department of Physics is officially the Department of Physics and Astronomy!” The change was approved by the Board of Regents on March 23 and was celebrated on June 3 in the James Fletcher Building. Physicists and astronomers alike came together over an assortment of space cake, Starbursts, Milky Way candy bars, and Starlight mints, to celebrate the landmark achievement. Kieda and Pierre Sokolsky, dean of the College of Science, both spoke briefly, highlighting the department achievements of the last year. Recognition was given to Zeke Dumke of the E.R. & E.W. Dave Kieda (right) after presenting a certificate of appreciation to Steve Denkers. Dumke Foundation, and to Steve Denkers of the Willard L. Eccles Foundation. Generous funding from both foundations have helped establish and develop the current astronomy program and its research. Astronomy courses were first taught on campus in the 1890s, as a part of the math department, and the university has had an on-campus observatory of one form or another for the last 50 years, but there was never a dedicated astronomy program until now. Within the department, astronomy research started with the discovery of a nova, by Professor Don Groom, and has continued for more than 35 years. For students, the department now offers a major degree program in Astronomy, and a minor as well. The title ‘Department of Physics’ is now a thing of the past. However, for the ‘Department of Physics and Astronomy’, when looking towards the future, the stars are the limit.
