Book Description
This is a rare book on a rare topic: it is about 'action' and the Principle of Least Action. A surprisingly well-kept secret, these ideas are at the heart of physical science and engineering. Physics is well known as being concerned with grand conservatory principles (e.g. the conservation of energy) but equally important is the optimization principle (such as getting somewhere in the shortest time or with the least resistance). The book explains: why an optimization principle underlies physics, what action is, what `the Hamiltonian' is, and how new insights into energy, space, and time arise. It assumes some background in the physical sciences, at the level of undergraduate science, but it is not a textbook. The requisite derivations and worked examples are given but may be skim-read if desired. The author draws from Cornelius Lanczos's book "The Variational Principles of Mechanics" (1949 and 1970). Lanczos was a brilliant mathematician and educator, but his book was for a postgraduate audience. The present book is no mere copy with the difficult bits left out - it is original, and a popularization. It aims to explain ideas rather than achieve technical competence, and to show how Least Action leads into the whole of physics.

Book Description
Energy is at the heart of physics and of huge importance to society and yet no book exists specifically to explain it, and in simple terms. In tracking the history of energy, this book is filled with the thrill of the chase, the mystery of smoke and mirrors, and presents a fascinating human-interest story. Moreover, following the history provides a crucial aid to understanding: this book explains the intellectual revolutions required to comprehend energy, revolutions as profound as those stemming from Relativity and Quantum Theory. Texts by Descartes, Leibniz, Bernoulli, d'Alembert, Lagrange, Hamilton, Boltzmann, Clausius, Carnot and others are made accessible, and the engines of Watt and Joule are explained. Many fascinating questions are covered, including: - Why just kinetic and potential energies - is one more fundamental than the other? - What are heat, temperature and action? - What is the Hamiltonian? - What have engines to do with physics? - Why did the steam-engine evolve only in England? - Why S=klogW works and why temperature is IT. Using only a minimum of mathematics, this book explains the emergence of the modern concept of energy, in all its forms: Hamilton's mechanics and how it shaped twentieth-century physics, and the meaning of kinetic energy, potential energy, temperature, action, and entropy. It is as much an explanation of fundamental physics as a history of the fascinating discoveries that lie behind our knowledge today.

Book Description
Thaddeus Golas is a lazy man. Laziness keeps him from believing that enlightenment demands effort, discipline, strict diet, non-smoking and other evidences of virtue. He found a way to enlighten himself - and you - with two sentences. The first is We are equal beings and the universe is our relations with each other. The second? The universe is made of one kind of entity; each one is alive, each determines the course of his own existence. If you remember this, that's all you really need to know to understand this book. Originally published in 1972, and in print for 15 years, THE LAZY MAN'S GUIDE TO ENLIGHTNMENT teaches you, amongst other things, how to feel good.

Book Description
NEW YORK TIMES BESTSELLER • Being a Lazy Genius isn't about doing more or doing less. It’s about doing what matters to you. “I could not be more excited about this book.”—Jenna Fischer, actor and cohost of the Office Ladies podcast The chorus of “shoulds” is loud. You should enjoy the moment, dream big, have it all, get up before the sun, track your water consumption, go on date nights, and be the best. Or maybe you should ignore what people think, live on dry shampoo, be a negligent PTA mom, have a dirty house, and claim your hot mess like a badge of honor. It’s so easy to feel overwhelmed by the mixed messages of what it means to live well. Kendra Adachi, the creator of the Lazy Genius movement, invites you to live well by your own definition and equips you to be a genius about what matters and lazy about what doesn’t. Everything from your morning routine to napping without guilt falls into place with Kendra’s thirteen Lazy Genius principles, including: • Decide once • Start small • Ask the Magic Question • Go in the right order • Schedule rest Discover a better way to approach your relationships, work, and piles of mail. Be who you are without the complication of everyone else’s “shoulds.” Do what matters, skip the rest, and be a person again.

Book Description
From social psychologist Dr. Devon Price, a conversational, stirring call to “a better, more human way to live” (Cal Newport, New York Times bestselling author) that examines the “laziness lie”—which falsely tells us we are not working or learning hard enough. Extra-curricular activities. Honors classes. 60-hour work weeks. Side hustles. Like many Americans, Dr. Devon Price believed that productivity was the best way to measure self-worth. Price was an overachiever from the start, graduating from both college and graduate school early, but that success came at a cost. After Price was diagnosed with a severe case of anemia and heart complications from overexertion, they were forced to examine the darker side of all this productivity. Laziness Does Not Exist explores the psychological underpinnings of the “laziness lie,” including its origins from the Puritans and how it has continued to proliferate as digital work tools have blurred the boundaries between work and life. Using in-depth research, Price explains that people today do far more work than nearly any other humans in history yet most of us often still feel we are not doing enough. Filled with practical and accessible advice for overcoming society’s pressure to do more, and featuring interviews with researchers, consultants, and experiences from real people drowning in too much work, Laziness Does Not Exist “is the book we all need right now” (Caroline Dooner, author of The F*ck It Diet).

Book Description
INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.
