Principles of Scientific Inquiry: Wave Phenomena 2014

December 5, 2014
PSI Presentations

How do you build a short pulse laser only from materials available 100 years ago? How do you make color holograms, explore how a violin works, measure the "Ether wind"? How can you trap particles with light or build a flute?

These are some of the questions which this year's students addressed independently in their experimental projects for "Principles of Scientific Inquiry", the lab component of Physics 15c.


2015 Goldhaber Prize Winners

November 25, 2014
Graduate students Dennis Huang, Siyuan Sun, Bo Liu, and Shu-Heng Shao (pictured above, clockwise from top left) are the winners of the 2015 Maurice and Gertrude Goldhaber Prize. The prize is awarded annually by the department to its most outstanding current PhD students after they pass their qualifying exams, based on their accomplishments, creativity, and innovative approaches to research, as determined by a vote of the faculty.

Observation of an Excited Bc+/- Meson State with the ATLAS Detector

Figure 1: Invariant mass distributions of the reconstructed Bc± → J/ψπ± candidates in 7 TeV data (top) and in 8 TeV data (bottom). The data are represented by the points with error bars (statistical only). The solid line is the projection of the results of the unbinned maximum likelihood fit to all candidates in the mass range 5620–6820 MeV. The dashed line is the projection of the background component of the same fit. [From G. Aad et al.


Lost and Found: A Science Symposium about Navigation

November 21, 2014

On November 14, 2014, experts from fields as far-ranging as human cognitive neuroscience and neural computation, animal life science, anthropology and culture, space science, current and future technology, and emergency management converged on Radcliffe’s annual Science Symposium to conduct a broad, cross-disciplinary investigation of navigation and way-finding.
