Program: 7:30 PM
Physics of Steam Trains by Lewis Epstein
Come join us and have a brew or two. Pablo will show you his Lionel trains, momentum conservation apparatus (pool table), as well as his Apollo 13 pinball machine. If there's a quorum, Lew will give a short talk on the Physics of Steam Trains! Don't be a party pooper!
Take the Whipple Exit from 101, westward (from either direction).
As soon as you cross the railroad tracks, turn left onto El Camino Real.
Go for about a mile and turn right onto Jefferson Avenue.
Go for about 1.1 miles and turn right onto Quartz Street.
Go 2 long blocks up the hill until you see a white mailbox, on the left,
in the ivy fence that says "424". Park on the street and walk down the driveway;
Rancho Robinson is behind the house on the street. Lost? Call (650) 400-9425 for help.

Dark Matter, Dark Energy: Mysteries of the Universe
Patricia Burchat, Stanford University
A scientific revolution in our understanding of the universe is under way.
In the last decade or so, cosmology has become an experimental science that's
led to two mysterious observations: about a quarter of the universe is "dark matter,"
which gravitationally attracts but is otherwise invisible, and about two-thirds
is "dark energy," which causes the universe to expand at an ever-increasing rate.
That means only a small fraction of the energy in the universe is composed of matter
that we understand! This class explores the evidence for dark matter and dark energy,
and the experiments being developed to investigate their fundamental nature.
Patricia Burchat studies differences in the time evolution of matter and antimatter
to try to understand why there is more matter than antimatter in the universe.
Currently a Guggenheim Fellow, she has held several leadership positions in the 550-person
international BABAR Collaboration at the Stanford Linear Accelerator Center.
She was appointed a Bass University Fellow in Undergraduate Education in 2004,
and a Fellow of the American Physical Society in 2001.
11:15 Invited Performance: “The Tesla Coil Show”
Hartmut Sadrozinski, UC Santa Cruz,
James J. Dann, Menlo School,
The Santa Cruz Institute for Particle Physics'
Outreach Program gets students electrified about
learning physics using a Tesla Coil which generates dazzling electrical arcs about
5 feet (1.5 meters) in length! See them demonstrate their Tesla Coil and
how to get students charged up to learn about physics.
12:15 LUNCH: Menlo School Cafeteria.
We encourage our attendees to eat lunch on campus to save time and also to give you an opportunity to converse with interesting luminaries like yourself! Lunches will be prepared by the Menlo School cafeteria and you will be asked to make your selection from a menu when you register.
I will post the menu online later this week rigvht here! Expect to pay about $12.
1:30 Raffle/Business Meeting:
Report from the Officers and other business.
Afternoon Program: Contributed Papers
Does Successful Prediction by a Theory Validate the Physical Model?
Dick Kidd • Diablo Valley College, firstname.lastname@example.org
|It is important that students recognize that
science is an ongoing evolution of inquiry and not some kind of infallible religion.
To promote critical thinking with regard to physics, seven historical examples are
discussed and a relevant and significant (but relatively unknown)
20th century controversy between competing models will be described.

Incorporating the Physics of Global Warming and Alternative Energy Sources in Physics Instruction
There are many opportunities within the standard curriculum for high-school and
college-physics classes to explain how issues involved with global warming and
alternative energy sources can be understood in terms of basic physics.
This lecture will present several examples and encourage the use of materials available on the website
Three examples are:
(1) The radiation energy balance of the earth as it absorbs sunlight and radiates away
thermal energy can be included in introductory thermodynamics.
(2) The impact of melting of floating ice versus terrestrial ice can be presented when discussing buoyancy.
(3) The power (which is the cube of the wind velocity) that can be generated by wind turbines can be included in describing mechanics.
LabVIEW Programming in an Advanced Physics Laboratory
Thomas Colton • firstname.lastname@example.org
Joel Fajans and Don Orlando • UC Berkeley
The physics department at UC Berkeley recently introduced a 3-week unit on computerized data acquisition, signal processing, and control into the junior-level electronics lab course. Students learn to program virtual instruments in the National Instruments LabVIEW graphical programming application. After an on-line LabVIEW tutorial, students construct a simple amplifier circuit and write a program to measure Boltzmann's constant from Johnson noise in a resistor. In the 2nd week, students build a scaled resistor digital to analog converter (DAC) and program an analog to digital converter (ADC). In 3rd week, students explore digital filtering techniques and write a proportional-integral-differential (PID) loop to control a magnetic levitator. Many students use LabVIEW for their final course project and subsequent research experiences. We will share lessons learned in adding 18 computer workstations and three weeks of material to an already-packed room and course.
The People's Physics Book
James H. Dann • email@example.com,
Kim Knestrick, Jason P. Murphy, James J. Dann • Menlo School, firstname.lastname@example.org
We have written a freely available alternative textbook for high school and community college
physics students and teachers. The textbook is in partnership with the Santa Cruz
Institute of Particle Physics Teacher Outreach Program. The textbook can be easily printed and
bound from source PDF documents at any copy shop. It is lightweight, easy to bring to and from class,
and contains a variety of problems suitable for regular, honors and AP physics.
The People's Physics Book is an inexpensive (free except for copying costs),
easy to use and practical study guide aimed for use by students, who have a knowledgeable teacher to guide them.
The book focuses on the physics alone and brings out the beauty and universality of the physics
(example: we do not spend time rewriting the same equation 5 different ways--we assume the teacher
will teach the students how to rearrange equations). The book does not go into great or repetitious detail;
nor have a lot of history or applications, neither does it offer solved problems;
thus it is not intended to replace the teacher and/or regular hardcover textbooks.
The book is ideal to be used to accompany a conceptual physics book or a website-like the physics classroom.
We will discuss the idea behind the book; how to obtain it; how to use the book in a variety of classes;
how to improve and contribute to future editions of the book;
and how the book can be used in conjunction with standard textbooks and online resources.
Flaws in Classical Thin Soap Film Theories
Robert Sprague • Foothill College (ret), email@example.com
When thin soap films are formed on a square and rectangular parallelepiped wire frame,
a flat film rectangle is formed parallel to one side of the wire frame.
The dimensions of this rectangle depend on the dimensions of the wire frame.
Classical plateau theory gives wrong dimensions for this rectangle that are
especially bad for a cubical parallelepiped wire frame. Classical minimum soap
film area theory also gives very different wrong dimensions that are especially
bad for the cubical wire frame. A new combination theory will be given
that agrees very well with experimental results for every square and rectangular parallelepiped wire frame.
Using Tape Timers with TI Graphing Calculators
Lee Amosslee • Carondelet High School, Concord. Lee@TeacherResourceExchange.ORG
Think you need motion detectors to have students analyze motion with technology?
Instead, try it with the relatively inexpensive tape timer
and the graphing calculators most of your students already have for their math classes.
This talk will present the basics of how to use data tables, formulas,
and curve matching on a TI 83/84, including graphing of p/t, v/t, and calculating the slope of each.
Experiments include simple one-dimensional motion, and acceleration of a system that includes
the traditional "falling mass accelerating a cart."
A double-sided "How-To" manual that includes the basic steps will be distributed.
Discussion of how to introduce your students to the operations of the tape timer will also be included.
Standards and Assessment—How’s That Workin’ Out for You?
Dean Baird • Rio Americano High School, Sacramento, firstname.lastname@example.org
We're five years into the annual administration of the California Standards Test (CST)
in 9–12 Physics. Has the state's adoption of standards and assessments
affected your instruction? If so, how? If not, why not? How much do you know
about your school's performance on the Physics CST? Does your district provide
you with meaningful statistics on your students' performance? Let's get together
and discuss the issues. This session will be more of a "crackelbarrel" discussion than a presentation.
