About the Author

R S
Teacher (retired)
I taught physics and electronics for over 30 years, mainly at A level in sixth form colleges. Quite a few years ago I wrote several physics books and contributed to others, it was so long ago I am sure they must all be out of print. In addition I have worked for the OU in the past and still do some examining work.
