Thalken explores how physics can be applied to martial arts.More than a body of facts, Thalken sees physics as a practical discipline: an approach that can be applied to any number of pursuits. His chosen pursuit is martial arts. As in physics, the author says, no authority or status can make a martial artist's technique effective. Testable and reproducible results hold all the power. His thesis is that by understanding the way the human body moves and balances, a martial artist can gain the upper hand on opponents who do not approach their sport scientifically. Thalken outlines the way concepts from physics reveal strategies in fightingthe center of mass is important for leg sweeps and grappling, hits that travel shorter distances will arrive with greater force and speed, etc. He also debunks common misconceptions about equipment. For example, boxing gloves are not safer than bare knuckles; while they distribute force over a wider area, causing fewer breaks in the skin, they allow the fist to strike with more momentum and hit hard surfaces (like the head) more frequently. He also delves into many of the myths propagated by media portrayals of martial arts as well as the pseudoscience propagated by practitioners of martial arts themselves. A relatively short book, the work is more primer than instruction manual, advocating a perspective as opposed to promoting individual exercises or training regimens. There is an infectious energy to Thalken's prose, one that sells both the no-nonsense combat analysis and the cool skepticism of the physics discussion. As a guidebook, the text has very little fat: section titles like, Where Is My Center of Mass, and Why Do I Care? keep readers assured Thalken isn't trying to force more information on them than needed. The author is an apt communicator of even the more abstract ideas, putting them into a simple, intuitive context. It's unclear if thinking like a physicist can actually win a fighter matches, but it certainly provides a new grammar for thinking about the ways in which our bodies move.An enlightening book for martial artists seeking a competitive edge. Kirkus Fight Like a Physicist is a cool concept that makes physics tangible for fans of fighting sports.As a martial arts practitioner with a doctorate in physics, Jason Thalken has an interesting perspective on fighting sports, and he applies his knowledge of scientific principles to his chosen sport in Fight Like a Physicist. Though there probably isn't quite enough material here for a full book, the early sections do a solid job explaining the physics in a relatable way that gives fighters some perspective on how to incorporate scientific knowledge to fight better.Fight Like a Physicist finds a nice middle ground in terms of the material's tone the writing is simple enough for its target audience to understand and apply, while it still delivers meaningful scientific concepts. For example, the book uses levers as a way to explain the relationship between distance and force, and explains how the dispersal of force on impact can make particular blows more or less effective.Thalken includes numerous charts and graphs throughout the book. Like many of the concepts he writes about, these visual representations will look familiar to anyone who took physics in high school, but may not have thought about the material since then. He throws in the occasional math box, to highlight mathematical concepts like the force curve or the center of mass, while using both equations and sample fight-based scenarios. Combined, these elements make Fight Like a Physicist both a useful primer and an enjoyable refresher.Though the early chapters are strong, the book does lose its way a bit late, with chapters that seem shoehorned in. Thalken includes a chapter about brain injuries affecting football players (including Chronic Traumatic Encephalopathy), and posits a theory about how applied force might manifest in such injuries. However, the author also has a patent pending on a new helmetwhich he discloses honestly, but which does make an already tangential chapter feel like a sales pitch at times.Other sections criticize practices like tai chi for their lack of scientific basis, or advocate fighting back against criminals in dangerous real-life situations, but these parts feel unnecessary, and the tone deviates from the book's strengths. They don't quite fit the fighting-sports theme, and the science in these chapters is less than clear cut, especially when compared to the universal principles discussed earlier.At its best, in the early chapters, Fight like a Physicist is a cool concept that makes physics tangible for fans of fighting sports, and can just as easily get more science-minded readers interested in those sports. -- Jeff Fleischer Foreword Reviews, March 12, 2015
