This is a delightful small book... It will be a good resource for lecturers, showing some nice examples of applications of the physical principles, and of especial interest to advanced undergraduates and postgraduates. The reader is encouraged to write computer codes to find solutions, and the student with a thirst to learn and the motivation to engage fully with the book will be amply rewarded.

Astronomers like the concept of back-of-the-envelope calculations. Such calculations help us get a handle on very complex problems that would otherwise require far more time and effort to solve properly. Prasenjit Saha and Paul A. Taylor build an introductory guide to astronomy on exactly this premise.
Nature Astronomy
A sophisticated text that will bring physical intuition for astronomy for mathematically able students. The computationally based problems are a welcome addition to better empower student learning.
