This volume investigates the foundational principles and historical development of Albert Einstein's special theory of relativity through a curated selection of primary source documents. C. W. Kilmister, a mathematician and physicist, compiles key papers to provide a technical overview of how the theory emerged from classical mechanics and electromagnetism. The text serves as a pedagogical tool for students to engage directly with the original arguments that redefined space and time.

Experts recognize this work as a useful historical reference for understanding the evolution of relativistic thought. Readers frequently note the academic density of the prose, which requires a solid background in undergraduate-level physics to fully comprehend.
