This section of the book "Spacetime and Geometry: An Introduction to General Relativity" by Sean Carroll provides an overview of the fundamental concepts in special relativity and flat spacetime. It covers topics such as the separation and combination of space and time, Lorentz transformations, vectors, dual vectors, tensors, Maxwell's equations, energy and momentum, and classical field theory. The chapter also includes exercises to reinforce the understanding of these concepts.This section of the book "Spacetime and Geometry: An Introduction to General Relativity" by Sean Carroll provides an overview of the fundamental concepts in special relativity and flat spacetime.
