Abstract

IT seems fairly certain that television will have a great future, but, like all inventions, it is difficult to predict when it will become commercially successful. Of the systems in use, that invented by Baird seems to have made the greatest progress, and this little book gives an excellent description of it in non-technical language. Perhaps too much stress is laid in the opening chapter on the atomic nature of electricity. It is not very instructive to quote numbers beyond our comprehension. A clear description is given of the photoelectric cell, which enables a varying light scattered by the object to be ‘televised’ into a varying current of electricity. The varying currents can then be changed by a neon lamp to a fluctuating light which can be received on a screen? for television, neon is found to be the best gas to use, as it responds instantaneously to changes in the current.
