Introduction to Classical Field Theory

This book is a short introduction to classical field theory, focusing on showcasing the role of fields in mediating action-at-a-distance interactions. Suitable technical machinery is developed to explore at some aspects of each of the four known fundamental forces in nature. Beginning with the physically-motivated introduction to field theory, the text covers the relativistic formulation of electromagnetism in great detail so that aspects of gravity and the nuclear interaction not usually encountered at the undergraduate level can be covered by using analogies with familiar electromagnetism.
