Great Formulas Explained - Physics, Mathematics, Economics

My congratulations to the author! The topics [from physics, mathematics, economics] are interesting and useful, and he explains these relatively simple equations fully, with examples worked out clearly, results in both S.I. units [kg, m, s] and English common units [pounds, feet, seconds]. From physics, M. Bextis has chosen: intensity, explosion, Mach cone, reverberation, Doppler, hurricanes, flow, traffic, gravity, projectile range, impact velocity, braking distance, centrifugal force, satellite speed, roller coaster loops, lift, airplane speed, momentum, energy forms, energy conservation, and heat. From mathematics, he presents: trigonometry, circles and spheres, quadratic equations, logarithmic identity, harmonic series, geometric series, and the Poisson distribution. From economics, he instructs about: inflation, doubling time and half-life, optimal price, annuity, queues, games of chance. His appendices cover conversion factors, unit prefixes [tera to pico], and references for his topics. The text is clear and accurate, yet conversational. As a retired physicist, I was familiar with many of the equations, but I still found it worthwhile to review and to deepen my understanding of related topics. I do some mentoring at openstudy.com, a site primarily for high school students, and I know that many of these equations have turned up in our discussions of their homework related to physics and math. New to me were sections on acoustic reverberation, hurricanes, traffic, harmonic series, optimal pricing, annuities, and queues. I intend to keep my copy of the book, on my Amazon kindle e-reader, near me as I interact with the students on-line at openstudy.com.

The book is short and well-written. Some of the pagination is off near the end, but beyond that, it worked well. Metin Bektas does a fine job explaining the equations from physics, mathematics, and economics.

This book provides a short overview of some common and less common formulas used in physics, math and economics. Each formula is introduced and then applied in several examples. Most of the sections are separate, making it possible to get in and out of the book without losing the "story". The explanations are well-written and easy to follow, you should be able to understand them without special knowledge. And the choice of formulas is diverse, there's always something new and interesting to discover. However, I'll only rate the book 4 stars because I felt that it missed depth in some parts. For example, I would have loved to have the historical background to the formulas or some more information on where they are applied. All in all, a great book for those curious about science.

A really informative and entertaining overview. The book is easy to read and you don't need to be a mathematician to understand it, a little bit of algebra will do the trick. The list of references make an excellent guide for further study. Recommended for anyone who wants to know why we learn math in school.

The author has managed to bring out great formula and simplify by real world examples, a unique book each formula has a small chapter that you can finish in less then 10 minutes. I finished the book after a year or so. When I had time or just bored I would run a chapter and enjoy the formula. Definitely gonna buy more books from the author

Many formula listed, but their origin is not explained and many of the formulas are of questionable usefulness. It would have been better to focus on a few of the most important ones and take a deep dive. But a pleasant read.

I really enjoyed exploring amazing and simple formulas that are used in complex areas like aviation, orbits, people statistics, etc.

Generally well written and accessible. I would have liked it if author spent more time deriving some of the material

Takes your understanding of fundamentals to a new height.

É um livro simples, mas precisa ter uma boa formação matemática de ensino médio. Eu realmente gostei do enfoque prático dado pelo autor.

¡Brutal! Entendiendo el término como sinónimo de extraordinario. Hace que los conceptos que explica parezcan simples y sencillos, algo que en temas de ciencias y matemáticas me parece muy difícil de lograr. Tengo seis libros de este señor y voy camino de completar la colección. Un consejo, si veis un libro de este autor considerar seriamente adquirirlo si el tema os interesa, no tiene pierde.

Il libro e' scritto in modo semplice e molto ben articolato. Le formule sono enunciate senza molti fronzoli e non e' necessario neppure un diploma per comprenderle (qualche radice quadrata....). Le formule presentate sono approssimate ma ottime e contengono anche termini come attrito e viscosità che permettono predizioni piu' realistiche. Interessanti e chiari gli esempi, che gettano una nuova luce su fenomeni che si incontrano ogni giorno o quasi. Unico appunto e' la brevità del libro che si legge in poche ore.

I wish I had read this book when I was still at school, because the author does a great job in revealing how powerful maths can be when applied to the "real world" and manages to demonstrate that formulas are not just abstract theory, that alone would have helped me tremendously and even made me love maths from the start. The book is very user friendly, well written and gets the ideas across without oversimplifying. You will need a bit of high school mathematics to follow it though. The only downside is the length of the book, it took me only a few hours to get through it. But at that price, this is acceptable. An excellent book for anyone wishing to understand what math is and what it can do.
