Optical elements manipulate light waves. They may be used to focus the light or to change the phase, the polarization, the direction, or the intensity of light. Many of these functions are often demonstrated with microwaves, since the devices normally available in teaching laboratories produce...
Digital computers use different kinds of memory, each of which is either volatile or nonvolatile. On most computers only the hard drive memory is nonvolatile, i.e., it retains all information stored on it when the power is off. When a computer is turned on, an operating system stored on the hard...
Rocket experiments demonstrating conservation of momentum will never fail to generate enthusiasm in undergraduate physics laboratories. In this paper, we describe tests on rockets from two vendors 1,2 that combine baking soda and vinegar for propulsion. The experiment compared two analytical...
In How to Solve It , accomplished mathematician and skilled communicator George Polya describes a four-step universal solving technique designed to help students develop mathematical problem-solving skills. By providing a glimpse at the grace with which experts solve problems, Polya provides...
Our school recently acquired 1 Vernier's Wireless Dynamics Sensor System (WDSS). The WDSS consists of a three-axis accelerometer, altimeter, and force sensor that has the ability to remotely collect data for later transfer to a computer.; 2 While our primary purpose for acquiring the WDSS was to...
This little problem arose because I was frustrated with the standard electromagnetism texts, which show the magnetic field due to a current-bearing wire outside the wire ∝1/; r and inside ∝; r . However, they never point out that the moving electrons must be influenced by the magnetic field...
In this paper I describe an in-class discussion activity aimed at helping elementary education majors in a physical science course think about issues surrounding the inclusion of “Intelligent Design” in public school science standards. I discuss the background instruction given, the content of...
