Knowledge of Physics, History, and Chemistry

The appeal of physics lies in its knowledge. Physics has many practical applications. For example, the discovery of electromagnetic induction made it possible to build generators, converting other forms of energy into electrical energy. This drove the development of the power industry and supplied the energy needed to run the many electrical devices of modern society.

Physics can also satisfy our curiosity. It helps us understand the nature of light. The debate over whether light is a particle or a wave lasted for many years, as scientists explored the question through various experiments. That process of discovery was full of mystery and wonder. Physics has also driven technological progress: advances in semiconductor physics have continually improved computer chip performance, while relativity provides the theoretical basis for the high-precision positioning of the Global Positioning System (GPS). These are just some examples of the tremendous impact physics has had on modern technology.
