Outreach Effort for Penn Physics and Astronomy

At the Penn Summer Science Academy (PSSA) students listen to a lecture, delivered from CERN by Professor Elliot Lipeles, on the discovery of a Higgs-like particle the day after the international announcement.


Reflective Self-Assembling Proteins

Prof. Alison Sweeney studies the biophysical properties of reflectin - a highly reflective and self-organizing squid protein found in cephalopods like the Hawaiian Bobtail squid shown here.


Large Hadron Collider - ATLAS Higgs candidate event

An event captured by the ATLAS detector in the search for a Higgs boson decaying into two Z bosons, one of which goes into a pair of electrons and two muons (the two tracks shown in red). There is no way to tell if this particular event comes from a Higgs decay or simply from a background event such as one containing two Z bosons.


Science Verification Images from DES

Topology and Liquid Crystals

Liquid crystal molecules can be molded into shapes which resemble a Hopf fibration, a complex shape from topology resembling a series of linked rings wrapped into a torus. This fascinating shape has applications in mathematics, quantum physics, and computer graphics.
