October 2013 Announcements

Two items:

The National AAPT winter meeting in Orlando is up for registration. see http://www.aapt.org/Conferences/wm2014/

Also: Beth Cunningham from the National Office sent me this today. Shout if you’re interested.

“I am seeking your assistance in finding an AAPT national member in your section to represent AAPT at an upcoming important conference in the region of your section.  The Conferences for Undergraduate Women in Physics (CUWIP) are three-day regional conferences for undergraduate physics majors.   The goal of the conferences is to help undergraduate women continue in physics by providing them with the opportunity to experience a professional conference, information about graduate school and professions in physics, and access to other women in physics at all career stages with whom they can share experiences, advice, and ideas.  The program includes research talks by faculty, panel discussions about graduate school and careers in physics, presentations and discussions about women in physics, laboratory tours, student research talks, and opportunities for students to interact.

The conferences are held simultaneously at eight different institutions of higher education.  The 2014 conferences will run Friday evening, January 17th, through Sunday afternoon, January 19th.  For more information about the conferences, see http://www.aps.org/programs/women/workshops/cuwip.cfm.  One of the locations for the conferences is University of Utah which is located in the Idaho-Utah section.  I need your assistance in finding a local AAPT national member who could represent AAPT and provide materials about careers in physics particularly involving teaching in high school or at the college or university level.  In addition, this representative can provide information about AAPT and the value of an AAPT membership in supporting careers in physics teaching.  The national AAPT office can provide materials for this representative to distribute.  If needed, we may be able to provide modest travel reimbursement if the volunteer requests support.


The leadership of AAPT understands the value of increasing the participation of women in physics careers.  AAPT’s current leadership includes four women: the current president, vice president, past president, and executive officer.  We are also keen to support programs to increase the number of women in physics, particularly as role models and mentors teaching physics to the next generation of scientists and citizens.  In fact, the AAPT Marketing Manager RaShonda Rosier (rrosier@aapt.org) is attending the conference at Florida State University and I am attending the conference at University of Maryland.


Can you find a local AAPT member who is willing to attend this conference as a representative of AAPT?  And, can you connect that individual to RaShonda and me by forwarding their contact information?  I would appreciate this information by October 31st so that RaShonda and I can coordinate registration and mailing of materials with this individual.  We can also assist this individual in contacting the conference local organizing committee.  As always, I appreciate your willingness to assist AAPT!

Warm regards,


I told her I’d do it if no one else wanted to.

Information about UVU:


Utah Valley University is just off of I-15 at exit 269. Please visit http://www.uvu.edu/visitors/visit/index.html for addition information and maps.


The UVU Physics Department is quite young. It has graduated just over 60 students since 2004 (its first graduating class).  The department’s graduates have been accepted to many graduate programs and several UVU physics alumni have their PhDs and are well established in research careers. The department has ten full time faculty. The faculty are active in several research areas including thermal acoustics, geophysics, medical physics, astronomy and aeronomy.


UVU has grown tremendously during the last decade and during the 2011-2012 academic year had the largest student body count of any of the institutions of higher education in the state of Utah. (The University of Utah has reclaimed that distinction for the present.)

Kent Gee and Tracianne Neilsen‘Sound’ physics? A discussion of acoustics in Utah’s sixth grade science curriculumAs part of Utah’s science core curriculum, sixth grade students are to learn about heat, light, and sound. Of the specific objectives listed for all three topics, the points related to investigating sound appear to be the most lacking and disconnected from the objectives found within the understandably more advanced Physics Core. Shortcomings of the current objectives and possible modifications that could help build a better foundation of physics concepts for students are described.


Tim WendlerAccurate Scientific Visualization in Research and Physics TeachingAccurate visualization is key in the expression and comprehension of physical principles. Many 3D animation software packages come with built-in numerical methods for a variety of fundamental classical systems. Scripting languages give access to low-level computational functionality, thereby revealing a virtual physics laboratory for teaching and research. Specific examples will be presented: Galilean relativistic hair, energy conservation in complex systems, scattering from a central force, and energy transfer in bi-molecular reactions.


Harold StokesLecture ClipsUsing Camtasia Studio software installed on a Lenovo Thinkpad tablet, I have made a large number of short videos of material discussed in class.


Jean-Francois Van HuelePseudoscience and AAPTThe recent National AAPT 2012 Winter Meeting in Ontario, CA featured several well-attended sessions on pseudoscience. I will report on what I learned from attending some of the talks. I will also relate how the learning experience may have been even better than the conference organizers intended.


Spencer PerryGatling Vortex CannonGenerating vortex rings by means of acoustical and mechanical energy. Vortex rings are an application of fluid dynamics, but they can be used to teach acoustics, Newton’s Laws, viscosity, pressure, and torque. The presentation will discuss our motivations for design and construction of the vortex cannon demos, what we learned about the relationships between parameters, and alternative methods of producing similar results. I will also discuss possible classroom applications and other possible applications outside the classroom.


Dallin S DurfeeA Classically Intuitive Spin on Quantum Angular MomentumI will discuss a way to connect the x, y, and z basis sets for the spin 1/2 system using a classical understanding of angular momentum. This method should help students to develop greater intuition for the quantum description of angular momentum, and highlights the connections between classical coordinate space and the Hilbert space used to describe quantum mechanical spin states.


Tracianne NeilsenPreliminary results of pre-class learning activitiesIt is significantly easier to create an effective learning experience during class if the students come prepared. In reality, this rarely happens because the students are busy with other things; thus it is necessary to require a graded assignment on the new material that is due prior to class as motivation. In an attempt to approach the Just-in-time Teaching methodology, pre-class learning activities (LA) have been implemented in the Descriptive Acoustics course to provide the students with meaningful engagement with the concepts before class. An LA consists of a hands-on interaction either with a simulation/applet on their computer or a small experiment. The students are required to submit one paragraph describing their experience and observations. Feedback from the students at the end of the first semester indicates that they generally enjoyed the learning activities and found them helpful.


Dennis PedersenCan Scientific Reasoning Ability and Epistemological Beliefs Limit Success in Introductory Physics?Research in Physics Education is shedding new light on the relationship between scientific reasoning ability, epistemological beliefs, and conceptual change in Introductory Physics. This talk will present data acquired from the Physics 123 course at BYU-Idaho in an ongoing effort to improve conceptual understanding among introductory Physics and Physical Science students.


Diana ColePhysics Education ResearchThe students in several of the mechanics/kinematics classes at the school were given an exam at the beginning of the semester. This exam tested their attitudes about science, their basic science knowledge, and their conceptual understanding of kinematics. I analyzed the results of this test and discovered a few interesting trends in the results, including a difference between male and female test scores as well as a correlation between the scores of the three parts of the test.


Adam RollPhysics Education Research IIPhysics is generally considered to be a difficult subject to truly understand. Our group is investigating how students best learn so that teachers can help students to understand physics better. With the data from a class of Physics 220-Electromagnetism students I am trying to find any statistically meaningful correlations between students’ backgrounds, their pre-course attitudes about science, their reasoning ability, and their conceptual understanding. these data will eventually be compared with post-course data for the same students and as well as data from other courses.


J. Ronald Galli and Farhang AmiriPHOTON MOMENTUM AND PRINCIPLES OF REFRACTION THROUGH A UNIFORMLY MOVING MEDIUMThe bending of light as it passes from one medium to another and undergoes a speed change is well established. Not so well established or understood is the change in photon momentum and the role that momentum plays in the refraction process. In particular, it is uncertain whether the momentum of a photon increases (P=nPo) or decreases ( P=Po/n) as a photon of momentum Po passes from a vacuum to a medium of refraction index n. This paper proposes that P=nPo and that the momentum change vector is perpendicular to the surface. We show that these two mutually inclusive assumptions can be used to get the relationships between the angles of incidence and refraction for all speeds of the moving medium.

13:15Rondo JefferyJumping Ring MovieKey features of this ever-popular physics demonstration will be presented which show that it is much more than a simple application of Lens’ Law. High-speed movies of the jump confirm theoretical predictions based on understanding the magnetic field in and around the extended iron core and the phase-shifted ring current.
13:30Steve ShropshireImpact of Outreach on Physics Enrollment at ISUIdaho State University Physics Outreach has many aspects, from workshops for teachers, demonstration presentations for schools and community groups, Science Olympics, science festivals, and a Haunted Science Lab. A brief overview of these programs will be provided, enrollment and Graduation data will be presented, and the impact outreach has had on enrollment will be discussed.
13:45Todd LinesLight, Sound, & Perception: A Physicist teaching Biology and PsychologyBYU-I, as an institution, has undertaken a major effort to revitalize our GE program. Our team was given the charge to make a GE science class where the content was relevant to incoming freshmen. The design was to be a “vertical slice” through science rather than a general survey, explaining one science topic deeply rather than giving a shallow overview of science. The hope was that we would teach many things, but have a purpose that would drive interest governed by the major goal, aiding retention. Our class seeks to explain how video presentations motivate behavior (movies, commercials, etc.). Our goal is to teach the physics, biology, and psychology of light and sound. This talk is a short report of the charge we were given, how we are executing it, and a preliminary report of our results.
14:00Brian PyperChanging Reasoning Ability in College StudentsReporting on continuing efforts to improve conceptual understanding in introductory physics courses by paying explicit attention to improving students’’ reasoning ability.

12 noonClaire ChowBiophysics Research: Investigating the Mechanisms of the Rho HelicaseThe termination of RNA transcription is a well-known phenomenon in the scientific community. While the exact mechanism behind transcription termination differs between prokaryotes and eukaryotes, in prokaryotes termination is often dependent on the actions of Rho. Rho is an ATP dependent helicase that acts to release the RNA from the rest of the transcription machinery upon completing of transcription. Even though it is broadly understood, the exact role Rho protein plays, during transcription, as well as its energy requirements have yet to be elucidated.This study attempts to better establish the energy requirement for Rho during transcription termination. The Fluorescence Resonance Energy Transfer (FRET) was used, which allowed us to better visualize the protein-nucleic acid interaction and molecular movement as a whole. During this study, Rho was analyzed under various concentrations of adenosine triphosphate (ATP). Results indicate that approximately 1mM of ATP is optimal to propel Rho along the RNA strand. However, adding a higher concentration of ATP did not increase Rho’s rate at which it moved along the RNA molecule. These finding not only gives insight into Rho’s minimal energy requirement but contributes to further understanding gene expression and regulation.

There’s a Springhill Suites and an AmericInn by the south interchange, and a Days Inn by the Main street exit on at the intersection of Hwy20 and Hwy33, and a Super 8 on the corner of 2nd West and Main Street. The Super 8 is walking distance to campus, the others aren’t.

The AmericInn is offering us a rate of $65.90. Use reservation code UTAHID0312.

The Springhill Suites is offering us a rate of $72 using reservation code AAPT.

Both these sets of rooms (about 15 rooms at each hotel) will be released Wednesday the 7th of March.

We weren’t able to negotiate anything with the others. They may have better rates.
