Accelerated Beats

Listening to this audio file you will hear the left and right hands beat together at 4 beats/measure for one measure.

Then at the start of the 2nd measure the right hand accelerates its beat rate speeding up by 3/2 beats per measure in each measure.  This acceleration goes on for two measures until the rate of the right hand is 7 beats/measure.  It takes 11 beats of the right hand to reach this new rate.

After reaching the new rate, the right hand stops accelerating and the two hands beat steadily, the left hand at 4 beats/measure; the right hand at 7 beats/measure.

Teaching Physics with Astronomy

From 2010 to 2012  Better Physics supported efforts to use the research results of modern astronomy and astrophysics to enrich undergraduate physics instruction. This site reports several efforts to this end.

Detectors for the CMB

Body: 

 

Dr. John Kovac, Assistant Professor of Astronomy and Physics at Harvard University, presented a two-part talk. First, he gave a gripping account of detector development, installation, and use at the South Pole Telescope; then he described his course in which undergraduates build a microwave horn, assemble the necessary electronics, and detect the cosmic microwave background.

Design, build, & test a CCD camera

Body: 

 

Dr. Zoran Ninkov, Professor in the Center for Imaging Science at Rochester Institute of Technology, described his year-long course in which his students learn and use basic physics and engineering to design and build a working CCD camera.  See, for example, http://spie.org/etop/2007/etop07coursesV.pdf.

Gamma-ray bursts, black holes, exoplanets

Body: 

 

Dr. George Ricker, Senior Research Scientist in MIT's Kavli Institute for Astrophysics and Space Research, described the work of four of his graduate students. Detector development was central to the Ph. D. education of each, opened new frontiers, and led to a career and leadership in astronomy or space science.

Advanced CCD and CMOS image sensor technology at MIT Lincoln Laboratory

Body: 

Dr. Vyshnavi Suntharalingam, Group Leader, Advanced Imaging Technology at MIT Lincoln Laboratory, took us through the refinements of design and fabrication that have made silicon and CCDs so important for astronomy. She reviewed the achievements of CCDs, the capabilities of CMOS devices, and some future prospects.

Basic physics of astronomy's detectors

Body: 

 

The lead-off speaker, Dr. James Beletic, Director of Astronomy & Civil Space at Teledyne Imaging Sensors (TIS) also chaired the session. He gave a fine overview of optical and infrared detectors and their physics.
