Theory of Knowledge Connections
Terminology used in electromagnetic field theory is extensive and can confuse people who are not directly involved. What effect can lack of clarity in terminology have on communicating scientific concepts to the public?
There is continued debate of the effects of electromagnetic waves on the health of humans, especially children. Is it justifiable to make use of scientific advances even if we do not know what their long term consequences may be?
Nature of Science
In 1831 Michael Faraday, using primitive equipment, observed a minute pulse of current in one coil of wire only when the current in a second coil of wire was switched on or off but nothing while a constant current was established. Faraday's observation of these small transient currents led him to perform experiments that led to his law of electromagnetic induction.
In the late 19th century Edison was a proponent of direct current electrical energy transmission while Westinghouse and Tesla favored alternating current transmission. The so called "battle of currents" had a significant impact on today's society.
Examples of exponential growth and decay pervade the whole of science. It is a clear example of the way that scientists use mathematics to model reality.
