NCNAAPT Business Meeting

Run by Claudia Winkler, NCNAAPT President

Next meeting will be at American River College in the Spring:

Would like to make afternoon session to be more Show & Tell with a longer length (10 min). Include not only new ideas but also “oldies but goodies” that new teachers may not know.

Potentially have a world-class astrophotographer for the Friday night reception

Potential Topics:

–  learn how to be better physics educators

– learn how to increase people entering Physics and bring in current topics

– potentially have speakers involved in green energy & environmentally topics

– Dual topics for high school & college

– potential speaker in physics education research

– current research topics (problems) facing Physics

– No Child Left Behind issues

Potential Locations:

– CSU Chico

– Lawrence Livermore National Lab

– Exploratorium

– Academy of Science (SF)

NCNAAPT Afternoon Session

“Taking a Ride on the Wild Side: The Successful Stardust Sample Return Mission to Comet 81P/Wild 2”

One of the rare sample return mission meant to analyze the composition of a comet. There are long term benefits to sample return missions including future study and analyses that were not developed or wanted at the time of the original mission. Stardust had to make three elliptical orbits of different sizes in order to get the right timing to collect from the comet. Sandford discusses the design of Stardust including specific design challenges such as the 6km/s average speed of particles within the coma of the comet. The Wild 2 comet uses areogel to collect material from the coma. After collection, the spacecraft returned to Earth’s orbit and only the collection capsule returned to earth. The spacecraft used a heat shield similar to the Apollo missions to return to Earth in Utah Test and Training Range. Sandford helped to collect the capsule in Utah which included several practice ones involving dropping mock capsules at the range. The December 15, 2006 issue of “Science” has a detailed article about the results. The results were surprising, samples were found of more complex materials than expected and some minerals that were usually found only in hotter conditions. Several samples were also a lot larger than expected and disagrees with the traditional theory that comets are made of miscellaneous interstellar material.

Dark Secrets: What Science Tells Us About the Hidden Universe: Free talk in Berkeley

Dark Secrets: What Science Tells Us About the Hidden Universe

admission free  •  monday, october 26, 2009  •  7:00 – 8:30 pm
Berkeley Repertory Theatre (Roda Stage)
2015 Addison St. Berkeley, CA 9470

No mystery is bigger than dark energy — the elusive force that makes up three-quarters of the Universe and is causing it to expand at an accelerating rate. KTVU Channel 2 health and science editor John Fowler will moderate a panel of Lawrence Berkeley National Laboratory scientists who use phenomena such as exploding stars and gravitational lenses to explore the dark cosmos.

Image of Saul PerlmutterSaul Perlmutter heads the Supernova Cosmology Project, which pioneered the use of precise observations of exploding stars to study the expansion of the Universe. His international team was one of two groups who independently discovered the amazing phenomenon known as dark energy, and he led a collaboration that designed a satellite to study the nature of this dark force. He is an astrophysicist at Berkeley Lab and a professor of physics at UC Berkeley.

Image of David SchlegelDavid Schlegel is a Berkeley Lab astrophysicist and the principal investigator of Baryon Oscillation Spectroscopic Survey (BOSS), the largest of four night-sky surveys being conducted in the third phase of the Sloan Digital Sky Survey, known as SDSS-III. BOSS will generate a 3-D map of two million galaxies and quasars, using a specially built instrument outfitted with 1,000 optical fibers and mounted on the SDSS telescope in New Mexico.

Image of Alexie LeauthaudAlexie Leauthaud is Chamberlain Fellow at Berkeley Lab. Her work probes dark matter in the Universe using a technique called gravitational lensing.  When gravity from a massive object such as a cluster of galaxies warps space around it, this can distort our view of the light from an even more distant object.  The scale and direction of this distortion allows astronomers to directly measure the properties of both dark matter and dark energy.
