An Experiment with Cellular Phones in General Physics Education(PDF,752KB)
Takashi Iwasaki,Chuo University, Japan
abstract---
Recently cellular phones are used worldwide as convenient communication
tools. In spite of that, very few people understand the underlying
physics. Of course, underlying mechanisms of other electrical
equipments such as TV, radio, and so on, are also not fully
understood by many people. However, cellular phones are used anytime
and anywhere, with or without partners, but can they be used
safely without the knowledge about their mechanisms? In fact, their
usage may occasionally threaten other people's life if used in improper
ways, such as disrupting pacemakers of the heart-disease
patients. As a result, the society may need to restrict their usage in
order to protect people's safety. Such restrictions might be imposed even if there is lack of correct
knowledge about them in order to prevent that some people may use them ignoring the safety of
the other people. Therefore, as cellular phones spread all over the world, it is important for us both
to understand their mechanisms scientifically and to learn their proper usage. Accordingly, we
believe that it is important to give the students the opportunity to understand their mechanisms.
In this paper, we would like report our trials of designing the cellular-phone experiments in general
physics educations for the science and engineering students.
