Spring 2013 Morning Invited Talks

Invited Talk: “Changes in the Teaching of Introductory Physics at Stanford” Chaya Nanavati or Stanford University

Chaya diChayascussed the existing structure that has an instructor that leads lectures and has Head TAs, Discussion TAs and Lab TAs that assist the smaller groups.  Often we encounter several barriers to change: Administration or Colleagues are often resistant to change and need convincing, materials and time are necessary for change. She suggests using the already developed resources from Maryland University, Harvard, CU Boulder, etc. on group work and student-centered learning. Eric Mazur has lots of resources and evidence that interactive engagement increases the post-test gain on the Force Concept Inventory test. Continue reading “Spring 2013 Morning Invited Talks”

Spring Section Conference at Foothill College: April 26-27, 2013

Join us at Foothill College in Los Altos Hills, CA (just 16 miles NW of San Jose, 40 miles south of San Francisco) for the spring conference of the Northern California/Nevada Section of the American Association of Physics Teachers. Starting with a social and physics show, and observatory tour Friday evening, followed by a full day of physics education speakers and workshops on Saturday.

Physics of Baseball

David KaganDavid Kagan, CSU Chico

All of David’s material related to the Physics of Baseball are available on his website: Phys.csuchico.edu/baseball

David demonstrated the Physics of the Baseball bat including the progression of the baseball bat. He explained how to find the center of percussion of the baseball bat as well as the center of vibration.  The “sweet spot” of a bat is where the center of percussion and the center of vibration meet which means that the player will minimize the jarring force of the bat. David showed us many high speed videos from the playoffs that show the compression of a baseball bat being hit and the reaction of the bat after the impact. David demonstrated his rubber bat that has no internal support so that it can create a standing wave. By putting together that information, your students can choose the correction direction that the bat will swing and even guess where the baseball will break if it is outside or inside of the sweet spot.

Pablo shared the physics of the splash hits in the San Francisco Giants Stadium. The ballpark has been designed for maximum home runs and the majority are hit to right field, where the ballpark meets the bay. He discussed the geometry of the park and where a home run is most likely hit.

He has more materials on the change in velocity of a ball hit on different planets, the Physics of a home run, etc. Visit his website for additional materials and videos.
