Summary
Starting from the common electric phenomena, electrons were discovered, and its behavior was quantized. Human has been using electricity to do many things. Nowadays, without electricity, human cannot live.
Electric phenomena always come together with magnetic phenomena. Maxwell’s 4 famous equations for describing the behavior of electric charge resulted the discovery of electromagnetic waves, include the visible light. Light, electricity, and magnetism are the 3 aspects of one matter particle.
In this book, I summarized the history for the study of electromagnetism, did all the calculations, and solved Maxwell’s equations by my own hands. Completing this, I developed the ideas for making powerful tools such as lasers, highly sensitive detectors, and extending human lifetimes. It really worth the effort.
