Dr. Sadri Hassani is an Adjunct Professor of physics at the University of Illinois at Urbana-Champaign, Urbana, IL, USA, and a Professor Emeritus at Illinois State University, Normal, IL, USA. With over 30 years’ experience in teaching various physics courses, he is the author of several books at the introductory, intermediate, and advanced undergraduate and graduate levels.

"The content of the book is unique, including topics such as interstellar travel, relativistic photography, spacetime triangle inequality, the proof of the fact that acceleration reduces aging, and connection between STR, spin, and antimatter. ...This is an impressive, unique book that should be beneficial for students, lecturers and explorers who are interested in STR." --Zentralblatt MATH
