The thought experiment proposed by Langevin in 1911, known under the popular names, "Clock Paradox" or "Twin Paradox", is the most surprising result of the theory of Relativity: A twin who travels to a star at nearly the velocity of light comes back to Earth and finds his twin brother much older. In over a century, several thousands of published articles debated both in favor of and against this result. Unique to the physics of Relativity, this baffling phenomenon is analyzed as a main goal of this book.

Among an incredible number of solutions, is there one of simplicity and clarity which may be accepted unanimously by all of the physics community? The answer is yes and this solution, which has its origin in Einstein himself, is developed in the framework of the Special Theory of Relativity. In detailing this solution, it is shown that the essential ingredient to understand the theory is the acceleration of the twins. All the models which do not include acceleration are incompatible with the original idea of Langevin. If one considers this phenomenon, several questions come to mind. Why did physicists debate excessively on the paradox and struggle to reach an agreement? Why was there resistance to integrate acceleration into their studies? Why is the solution developed in this book known only by a minority of scientists?

Written for physicists, historians and philosophers of science, this book seeks to answer these questions based on (1) the psychological difficulty to accept the theoretical results, and (2) the fact that scientific knowledge is not uniformly distributed among scientists.

This book is the real deal
Format: Paperback
This book is the real deal. I found it to be eye-opening, because, despite sounding very advanced and almost next-level, the attacks accompanied by source code show how simple and effective they are in reality. This book seemed light at first (200 pages), so I was skeptical at it's ability to really tackle advanced topics, but I will say I was very pleasantly surprised. Those two hundred pages are action packed and filled with jaw-dropping 'this is cool' moments. My only gripe with it is that it's a little formulaic, with the social engineering being shoehorned into every attack, and maybe pushing the whole APT thing too much, like when you really want something to become 'a thing'. Do we really need to socially engineer payloads using the same formula for all of the attacks? Not even one 'ha Ked the router with boring Cisco exploits' example? I guess it wouldn't make for an entertaining book.

Best pentest book read to date
Format: Paperback
This is the best penetration testing book that I have ever read to date. There is such a depth of understanding of penetration testing that is conveyed in this book in the way that the author is able to portray highly advanced topics in a conceptually understandable way. A novice might not be able to follow the text, as it is advanced, but for anyone looking to open their mindset up to becoming a more effective penetration tester, I HIGHLY advise this book.

Worth every penny
Format: Paperback
This book is in a class of its own compared to other security and pentesting books. I would highly recommend to anyone interested or currently working in network security. Instead of simply explaining how to use common pentesting tools, Wil Allsopp explains how they work and how to write your own custom tools from the ground up. Even if you do not have a programming background, it is worth understanding how an attacker can infiltrate a "secure" network without being detected.

Format: Paperback
Bought yesterday, can't put it down -- will reread it again this week. This book is a solid gold mine on pulling our InfoSec heads out of our InfoSec tailpipes and focusing on the modes and methods our real adversaries are using. (Pro Tip: They aren't using crappy malware, so if you're InfoSec program is built on stopping malware you should be concerned.) We all hear about the social engineering component to an effective attack, but to see it so effectively used over and over again with Wil's case studies really drives home the point. If you're involved in either the management of an Information Security program, or involved in the more tactical parts of penetration testing, I'd put this on your short list of books to read this year. I hope he does a follow-up.
