This revised edition of an extremely clear Navy training manual leaves nothing to be desired in its presentation. Thorough in its coverage of basic theory, from the lever and inclined plane to internal combustion engines and power trains, it requires nothing more than an understanding of the most elementary mathematics. Beginning with the simplest of machines — the lever — the text proceeds to discussions of the block and tackle (pulleys and hoists), wheel and axle, the inclined plane and the wedge, the screw, and different types of gears (simple, spur, bevel, herringbone, spiral, worm, etc.). A chapter on the concept of work discusses the measurement of work, friction, and efficiency; this is followed by investigations of power, force, and pressure, with explanations of the uses of scales, balances, gauges, and barometers. The fundamentals of hydrostatic and hydraulic machines (such as the hydraulic braking system and the hydraulic press) are discussed in detail. The remaining chapters cover machine elements (bearings and springs), basic mechanisms (gear differential, couplings, cams, clutches), the internal combustion engine and power trains (including explanations of various transmission systems — synchromesh, auxiliary, etc.). Every concept is clearly defined, and discussions always build easily from elementary theory to specific applications familiar to anyone with the slightest interest in mechanics. Important concepts, machine components, and techniques are clearly illustrated in more than 200 diagrams, drawings, and cross-sections that reveal inner workings — all of these help to clarify even further an already clear and well-organized presentation. Although it was originally designed for use in U.S. Naval Training Schools, this book can be used to great advantage as a basic text in mechanical engineering in standard technical schools, and it will be immensely valuable even to lay readers who desire a basic knowledge of mechanics.

Anyone who truly wants to understand general relativity, quantum field theory or any other area of modern physics first needs to master Lagrangian mechanics.The issue with most resources teaching Lagrangian mechanics is that they don't truly teach you the why behind it. But what if it didn't have to be that way? What if you could truly learn Lagrangian mechanics the right way?The truth is that trying to understand physics at a deep level without understanding Lagrangian mechanics is like driving a car without a steering wheel – you’ll eventually run into a wall and not be able to move forward anymore.The issue is that Lagrangian mechanics is often taught in a way that does not truly explain why it's needed and instead leaves you wondering “who cares about this?”The true reason why Lagrangian mechanics is so incredibly powerful is that it gives you a general framework for describing literally any area of modern physics.This is the reason why Lagrangian mechanics exists, but almost no one will teach you it this way... even though they should.Whether you want to learn:ElectrodynamicsSpecial and general relativityQuantum field theoryString theoryYou absolutely need to have a deep understanding of Lagrangian mechanics to even get started on any of these topics.However, getting started and specifically knowing where to start is often the most difficult part. It would be nice to have a dedicated resource that introduces Lagrangian mechanics completely from scratch and gives you everything in one place.Well, that's exactly what this book will give you.You'll learn Lagrangian mechanics in a completely unique way you've likely never seen before - as both a fundamental framework for advanced modern physics, but also as an incredibly powerful problem solving tool.Lagrangian Mechanics For The Non-Physicist is a complete resource specifically designed to teach you everything you'd possibly need to know about Lagrangian mechanics and the foundations of modern physics - the fundamentals, prerequisites, theory, math and practical applications. It's all here.Some of the interesting you'll be able to learn from this book include:The intuition and proper motivation for why Lagrangian mechanics works and how it's useful in the first place as well as why the principle of stationary action makes senseCalculus of variations - the area of math Lagrangian mechanics uses - from the ground up, starting from the very basic ideas of single-variable calculusThe framework of Lagrangian mechanics, how to set up and solve any Lagrangian mechanics problem in a consistent step-by-step fashionA deeper dive into topics like generalized coordinates, generalized momenta, Lagrange multipliers and solving problems with constraintsAdvanced topics not covered in most other books - the most notable ones including friction and non-conservative forces in Lagrangian mechanics, solving statics problems with the principle of virtual work as well as a bottom-up approach to d'Alembert's principleThe relation between symmetries and conservation laws, described by Noether's theorem, as well as a precise description of what we even mean by symmetries in physicsSome advanced applications to modern physics, such as relativistic energy conservation and conservation of probability in quantum mechanics Read more

''Beautifully clear explanations of famously "difficult" things ... It almost makes you think you could have been a Newton yourself'' John Gribbin Here is the ultimate master class in modern physics.

The conservation of energy, the second law of thermodynamics, the theory of relativity, quantum mechanics­­together, these concepts form the foundation upon which modern physics was built. But the influence of these four landmark ideas has extended far beyond hard science. There is no aspect of twentieth-century culture­­including the arts, social sciences, philosophy, and politics­­that has not been profoundly influenced by them.In Great Ideas in Physics, Alan Lightman clearly explains the physics behind each of the four great ideas and deftly untangles for lay readers such knotty concepts as entropy, the relativity of time, and the Heisenberg uncertainty principle. Throughout the book he uses excerpts from the writings of scientific luminaries such as Newton, Kelvin, Einstein, and de Broglie to help place each in its proper historical perspective. And with the help of expertly annotated passages from the works of dozens of writers, philosophers, artists, and social theorists, Lightman explores the two-way influences of these landmark scientific concepts on our entire human culture and the world of ideas.

A Nobel-winning physicist argues that fundamental physical laws are found not in the world of atoms, but in the macroscopic world around us In this age of superstring theories and Big Bang cosmology, we're used to thinking of the unknown as impossibly distant from our everyday lives. But in A Different Universe, Nobel Laureate Robert Laughlin argues that the scientific frontier is right under our fingers. Instead of looking for ultimate theories, Laughlin considers the world of emergent properties-meaning the properties, such as the hardness and shape of a crystal, that result from the organization of large numbers of atoms. Laughlin shows us how the most fundamental laws of physics are in fact emergent. A Different Universe is a truly mind-bending book that shows us why everything we think about fundamental physical laws needs to change. Read more

This book takes the student from the Newtonian mechanics typically taught in the first and the second year to the areas of recent research. The discussion of topics such as invariance, Hamiltonian-Jacobi theory, and action-angle variables is especially complete; the last includes a discussion of the Hannay angle, not found in other texts. The final chapter is an introduction to the dynamics of nonlinear nondissipative systems. Connections with other areas of physics which the student is likely to be studying at the same time, such as electromagnetism and quantum mechanics, are made where possible. There is thus a discussion of electromagnetic field momentum and mechanical"hidden" momentum in the quasi-static interaction of an electric charge and a magnet. This discussion, among other things explains the"(e/c)A" term in the canonical momentum of a charged particle in an electromagnetic field. There is also a brief introduction to path integrals and their connection with Hamilton's principle, and the relation between the Hamilton-Jacobi equation of mechanics, the eikonal equation of optics, and the Schrödinger equation of quantum mechanics.The text contains 115 exercises. This text is suitable for a course in classical mechanics at the advanced undergraduate level. Read more
