Stop choosing between speed and safety. Master the language that gives you both.For decades, developers have been forced to make a trade-off: the raw performance of C/C++ (at the cost of memory safety) or the safety of languages like Java and Python (at the cost of garbage collectors and runtime overhead). Rust solves this problem, and "Rust for Developers" is your practical, project-based guide to mastering it.This book is written for you: the experienced ...

This book analyzes a little-known but highly significant document that played a key role in early nuclear history: the Frisch-Peierls memorandum of March 1940. Prepared by Otto Frisch and Rudolf Peierls, refugee European physicists then at the University of Birmingham, this 10-page document described the physics behind the possibility of creating nuclear weapons utilizing a chain reaction with uranium-235, as well as the associated military, strategic, and ethical implications of such weap...

This book provides a guide to the people, places, artifacts, events, terminology, scientific concepts, groups, critical documents, and code phrases associated with the Manhattan Project. It is of interest to all readers/researchers (students, journalists, policy-makers, specialist and non-specialist instructors and scientists) who need to rapidly access authoritative, self-contained definitions/descriptions of such items and references to authoritative sources. The individual entries are e...

Kepler’s three laws of planetary motion were a stunning development in human intellectual history. This second edition is a concise, self-contained treatment of Kepler/Newton planetary orbits at the level of an advanced undergraduate physics student. New to this edition are elements such as a detailed derivation of Newton’s shell-point equivalency theorem, a revised derivation of the polar equation for an ellipse, Kepler’s Third Law for non-inverse-square central potentials, a chapter on t...

Quantum mechanics is one of the most fascinating elements of the physics curriculum, but its conceptual nuances and mathematical complexity can be daunting for beginning students. This user-friendly text is designed for a one-semester course which bridges the gap between sophomore-level treatments and advanced undergraduate/lower-graduate courses. Qualitative explanations and descriptions of historical background are combined with detailed mathematical analyses to help students establish a...

The development of nuclear weapons during the Manhattan Project is one of the most significant scientific events of the twentieth century. This revised and updated 4th edition explores the challenges that faced the scientists and engineers of the Manhattan Project. It gives a clear introduction to fission weapons at the level of an upper-year undergraduate physics student by examining the details of nuclear reactions, their energy release, analytic and numerical models of the fission proce...

The development of nuclear weapons during the Manhattan Project is one of the most significant scientific events of the twentieth century. This book, prepared by a gifted teacher of physics, explores the challenges that faced the members of the Manhattan project. In doing so it gives a clear introduction to fission weapons at the level of an upper-level undergraduate physics student. Details of nuclear reactions, their energy release, the fission process, how critical masses can be estimat...

The development of man's understanding of planetary motions is the crown jewel of Newtonian mechanics. This book offers a concise but self-contained handbook-length treatment of this historically important topic for students at about the third-year-level of an undergraduate physics curriculum. After opening with a review of Kepler’s three laws of planetary motion, it proceeds to analyze the general dynamics of “central force” orbits in spherical coordinates, how elliptical orbits satisfy N...
