Egdall, Ira Mark – Physics Teacher, 2014
In this paper, I describe a lay course in special relativity (SR) given at the Osher Lifelong Learning Institutes (OLLI's) at Florida International University and the University of Miami. Courses are also offered in general relativity quantum theory cosmology the nature of time, and the fine-tuned universe. Each course is presented in six…

Aubrecht, Gordon J., II; French, Anthony P.; Iona, Mario – Physics Teacher, 2011
As all physicists know, all units are arbitrary. The numbering system is anthropocentric; for example, the Celsius scale of temperature has 100 degrees between the boiling point of water at STP and the freezing point of water. The number 100 is chosen because human beings have 10 fingers. The best units might be based on physical constants, for…

Amann, George; Mader, Jan; Matsler, Karen Jo; Nelson, Jim – Physics Teacher, 2011
A train barrels directly toward a stone wall. It looks like a disaster is inevitable. Suddenly, a group of railroad workers run to a switch that changes the direction of the train. They reroute the train onto a new track by throwing the switch just in time. Perhaps you had not known what to do, nor were you strong enough to do it yourself, but you…

Egdall, Mark – Physics Teacher, 2009
This paper describes a lay course on general relativity (GR) given at the Osher Lifelong Learning Institute at Florida International University. It is presented in six hour-and-a-half weekly sessions. Other courses offered by the author include special relativity (which precedes the course described here), quantum theory, and cosmology. Students…

Brichta, J. P.; Bizheva, K.; Sanderson, J. H.; Holbrook, J. – Physics Teacher, 2009
We have developed an easy-to-use online tutorial generator designed to allow instructors to make tutorials quickly and with a minimal learning curve. The motivation was to create a generator that would allow instructors to create tutorials as needed and possibly build up a bank of tutorials over a number of years. A key design feature of the…

Cohen, Bernard L. – Physics Teacher, 2008
It is often stated that the physical properties of our universe are "fine tuned"--that is, they must be almost exactly as they are to make the development of intelligent life possible. The implications of this statement, called the "anthropic principle," have been widely discussed in a philosophical context, but the scientific basis for the…
