How did James Clerk Maxwell build upon the work of Michael Faraday? How do astronomers today benefit from scientific work done in the middle of the 19th century? Since the birth of classical physics, the greatest advancements in knowledge have come from bringing together different fields of study. Even the early steps in physics—such as an unexpected unity among electricity, magnetism, and light—united what were thought at the time to be wildly different areas of study. Theoretical physicist Michio Kaku discusses the history of electromagnetic theory in his book The God Equation. Take a look.
