Why don't you give exact delivery time?
Delivery time is estimated on our previous experiences. We give estimations only, because we order from outside Hungary, and the delivery time mainly depends on how quickly the publisher supplies the book. Faster or slower deliveries both happen, but we do our best to supply as quickly as possible.

Short description:
Working physicists, especially astrophysicists, value `back-of-the-envelope' calculations -- short elegant computations or arguments that start from general principles and lead to interesting results. This book guides advanced undergraduates and lower graduates on how to understand astrophysics using general principles and concise calculations.
MoreLong description:
Working physicists, and especially astrophysicists, value a good `back-of-the-envelope' calculation, meaning a short, elegant computation or argument that starts from general principles and leads to an interesting result. This book guides students on how to understand astrophysics using general principles and concise calculations -- endeavouring to be elegant where possible and using short computer programs where necessary.
The material proceeds in approximate historical order. The book begins with the Enlightenment-era insight that the orbits of the planets is easy, but the orbit of the Moon is a real headache, and continues to deterministic chaos. This is followed by a chapter on spacetime and black holes. Four chapters reveal how microphysics, especially quantum mechanics, allow us to understand how stars work. The last two chapters are about cosmology, bringing us to 21st-century developments on the microwave background and gravitational waves.
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.
