Design and Alignment of the Hilbert Telescope for use in an Undergraduate Laboratory

A Ritchey–Chrétien telescope, named in memory of Robert S. Hilbert, was designed and constructed for use in an undergraduate laboratory. It will also be valuable in demonstrating multinodal aberration in a controlled environment in which misalignment would be purposely introduced to the system to display the resulting aberration in the image. Testing of the secondary mirror concluded with positive results. Testing of the primary mirror was hindered by the incorrect assembly of the Offner Null lenses that were used to explore aberrations, but ultimately concluded with results that suggested little flaw in the accuracy of the mirror. After multiple careful assemblies of the system, methods of alignment in the lab were improved and resulted in images that were detectable by the CCD camera, though there is room for improvement before the system could be used to create controlled multinodal aberration for study. The nature of the aberrations presently produced by the system due to misalignment must be better understood before any experiments are run that would introduce any external aberration not intrinsic to the fundamental setup.

Archaeogeophysics in Cyprus 2012

We will be talking about the KAMBE team and the work we did in Cyprus, relating to Archaeogeophysics, and the study of Archaeological remains, using Physics concepts. We will talk briefly about the history of the KAMBE team, and then focus more on the Data that we obtained and processed this summer, as well as briefly talking about the experience of working abroad with Ithaca College.

A Foam Model for Bread Development 

Here a model for the geometry of two dimensional bread is investigated. The incorporated model takes into consideration the interior structure of the gases in a bread foam. Using the calculus of variations, a minimal configuration is found with respect to the gravitational potential and surface energy of the dough. We compare the resulting configurations to previous models of bread as a liquid drop by comparing the discrete curvatures of the convex hull from the found minimal configurations. Elementary statistics are also incorporated to compare the two models.

Public Viewing Night at the Clinton Ford Observatory!

You are invited to join the Ithaca College Department of Physics for a Public Viewing of the night sky at the Clinton B. Ford Observatory.

8:00 PM - 10:00 PM Friday October 26, 2012

To attend a Public Night:
Just show up at the vehicle 'turn around' in front of the entrances of Smiddy Hall and CHS (F lot side).  A shuttle van will make regular runs to convey people up to the observatory and back down. Please note that there is NO parking available up at the observatory and that the access road is NOT lighted. For your own safety, please do not walk up.

Bad Weather Plan:
The "go/no-go" decision for any public night will be made at 3:30 pm on the scheduled date. Our web page and the recorded message at the observatory will be updated shortly thereafter to reflect the decision for that evening. So if you check our website or call the observatory at 607-274-3012 after 4:00 pm you will get the final decision for that evening.

Physics Fall Seminar Series at 12:10 in CNS 204 with Dr. Angela Biselli, Fairfield University (Fairfield CT)

Talk Entitled: What we are really made of: an introduction to the subatomic world of nucleons, resonances and quarks and to how physicists explore it.

Since the time of ancient Greek philosophers, mankind has been trying to characterize matter in terms of fundamental building blocks. The modern vision is that matter is made of quarks and leptons. Although an enormous progress has been made in the past century in describing the world around us in terms of these particles, nuclear and high energy physicists continue to experimentally explore matter to gain additional knowledge about these particles, their properties and their interactions with each other. To explore the microscopic the world of elementary particles, physicists accelerate them, scatter them against other particles or against each other and look at the outcome of the reaction. In this talk I will present the experimental program of Jefferson Laboratory in VA, with particular focus on the study of nucleon structure using Deeply Virtual Compton Scattering.
