movies and TV shows. That’s not because space physics is difficult or obscure – most of the details were understood by the end of the 18th century – but because it can often be bafflingly counter-intuitive for a general audience. The purpose of this book isn’t to criticize or debunk popular sci-fi depictions, which can be very entertaining, but to focus on how space physics really works. This is done with the aid of numerous practical illustrations taken from the works of serious science fiction authors – from Jules Verne and Arthur C. Clarke to Larry Niven and Andy Weir – who have taken positive pleasure in getting their scientific facts right.Par Mark Denny. 2007
A deep dive into pivotal technological advances in areas from warfare to time measurement. “A wonderful combination of history and…
physics.” —Mark Kidger, author of Astronomical EnigmasIngenium is medieval English vernacular for “an ingenious contrivance.” In this fascinating book, physicist Mark Denny considers five such contrivances—the bow and arrow, the waterwheel, the counterpoise siege engine (including the trebuchet), the pendulum clock anchor escapement, and the centrifugal governor—and demonstrates how they literally changed the world. Interweaving an entertaining narrative with diagrams, equations, and drawings, Denny shares the history of each device, explains the physics behind it, and describes how it was used, how it evolved, and why it is significant in today’s world.Consider the bow and arrow, which transformed warfare by allowing soldiers to attack their enemies at a safe distance. Or the waterwheel, which enabled Old World civilizations to grind grain, pump water, and power machines during a period of extreme labor shortages. Medieval warriors engaged in an early form of biological warfare by using the trebuchet to launch dead animals or plague-ridden corpses over enormous fortress walls. The pendulum clock forever enslaved modern humans to the clock by linking the accurate measure of time to the burdens of schedules, deadlines, promptness, and tardiness. And the centrifugal governor gave rise to an entire branch of modern engineering science: feedback control.Reflecting on the inventors of these ancient machines and the times in which they lived, Denny concludes with thought-provoking observations about inventors, inventiveness, genius, and innovation. Whether you dream of making a better mousetrap or launching pumpkins into the stratosphere, Ingenium will tickle your fancy.Par Ian F. Verstegen, Laura Messina-Argenton, Tiziano Agostini, Tamara Prest. 2022
How does a visual artist manage to narrate a story, which has a sequential and therefore temporal progression, using a…
static medium consisting solely of spatial sign elements and, what is more, in a single image? This is the question on which this work is based, posed by its designer, Alberto Argenton, to whose memory it is dedicated. The first explanation usually given by scholars in the field is that the artist solves the problem by depicting the same character in a number of scenes, thus giving indirect evidence of events taking place at different times. This book shows that artists, in addition to the repetition of characters, devise other spatial perceptual-representational strategies for organising the episodes that constitute a story and, therefore, showing time. Resorting to the psychology of art of a Gestalt matrix, the book offers ha formattato: Italiano (Italia) Codice campo modificato ha formattato: Italiano (Italia) ha formattato: Italiano (Italia) researchers, graduates, advanced undergraduates, and professionals a description of a large continuous pictorial narrative repertoire (1000 works) and an in-depth analysis of the perceptual-representational strategies employed by artists from the 6th to the 17th century in a group of 100 works narrating the story of Adam and Eve.Par C.

TIPERs: Sensemaking Tasks for Introductory Physics gives introductory physics students the type of practice they need to promote a conceptual…
understanding of problem solving. This supplementary text helps students to connect the physical rules of the universe with the mathematical tools used to express them. The exercises in this workbook are intended to promote sensemaking. The various formats of the questions are difficult to solve just by using physics equations as formulas. Students will need to develop a solid qualitative understanding of the concepts, principles, and relationships in physics. In addition, they will have to decide what is relevant and what isn’t, which equations apply and which don’t, and what the equations tell one about physical situations. The goal is that when students are given a physics problem where they are asked solve for an unknown quantity, they will understand the physics of the problem in addition to finding the answer.Par Antonio Padilla. 2022
A fun, dazzling exploration of the strange numbers that illuminate the ultimate nature of reality.For particularly brilliant theoretical physicists like…
James Clerk Maxwell, Paul Dirac, or Albert Einstein, the search for mathematical truths led to strange new understandings of the ultimate nature of reality. But what are these truths? What are the mysterious numbers that explain the universe? In Fantastic Numbers and Where to Find Them, the leading theoretical physicist and YouTube star Antonio Padilla takes us on an irreverent cosmic tour of nine of the most extraordinary numbers in physics, offering a startling picture of how the universe works. These strange numbers include Graham’s number, which is so large that if you thought about it in the wrong way, your head would collapse into a singularity; TREE(3), whose finite nature can never be definitively proved, because to do so would take so much time that the universe would experience a Poincaré Recurrence—resetting to precisely the state it currently holds, down to the arrangement of individual atoms; and 10^{-120}, measuring the desperately unlikely balance of energy needed to allow the universe to exist for more than just a moment, to extend beyond the size of a single atom—in other words, the mystery of our unexpected universe.Leading us down the rabbit hole to a deeper understanding of reality, Padilla explains how these unusual numbers are the key to understanding such mind-boggling phenomena as black holes, relativity, and the problem of the cosmological constant—that the two best and most rigorously tested ways of understanding the universe contradict one another. Fantastic Numbers and Where to Find Them is a combination of popular and cutting-edge science—and a lively, entertaining, and even funny exploration of the most fundamental truths about the universe.This book analyzes the development of space light-fiber coupling research, highlights its importance, examines the underlying theory and key problems,…
and elaborates on methods to improve the space light-fiber coupling efficiency. Starting from the basic theory of electromagnetic field, the transmission characteristics of light in optical fibers are expounded, and the coupling characteristics of optical signals of different modes are investigated.

atomic-level dynamics and leading to experimentally verifiable descriptions of macroscopic properties such as elastic and viscoelastic moduli, plasticity, phonons and vibrational spectra, and thermal properties. This theory begins with the assumption of the undeniable existence of an “amorphous lattice”, which allows one to relegate the theoretical uncertainties about the ultimate nature of the glass transition to a subsidiary role and thus take a more pragmatic approach towards the modelling of physical properties. The book introduces the reader not only to the subtle physical concepts underlying the dynamics, mechanics, and statistical physics of glasses and amorphous solids, but also to the essential mathematical and numerical methods that cannot be readily gleaned from specialized literature since they are spread out among many often technically demanding papers. These methods are presented in this book in such a way as to be sufficiently general, allowing for the mathematical or numerical description of novel physical phenomena observed in many different types of amorphous solids (including soft and granular systems), regardless of the atomistic details and particular chemistry of the material. This monograph is aimed at researchers and graduate-level students in physics, materials science, physical chemistry and engineering working in the areas of amorphous materials, soft matter and granular systems, statistical physics, continuum mechanics, plasticity, and solid mechanics. It is also particularly well suited to those working on molecular dynamics simulations, molecular coarse-grained simulations, as well as ab initio atomistic and DFT methods for solid-state and materials science.Par Chaoyang Zhang, Jing Huang, Rupeng Bu. 2023
This book highlights the intrinsic structures of all kinds of energetic compounds and some structure–property relationships therein. Energetic materials are…
a class of energy materials that can transiently release a large amount of gases and heat by self-redox after stimulated and usually refer to explosives, propellants and pyrotechnics. Nowadays, in combination with various theories and simulation-aided material design technologies, many new kinds of energetic materials like energetic extended solids, energetic ionic salts, energetic metal organic frames, energetic co-crystals and energetic perovskites have been created, in addition to traditional energetic molecular crystals. It is somewhat dazzling, and an issue of how we can understand these new types of energetic materials is raised. In the past about 20 years, we were immersed in the computational energetic materials. By means of defining a concept of intrinsic structures of energetic materials, which refers to the crystal packing structure of energetic materials, as well as molecule for molecular solid specially, the microscopic structures have been mostly clarified, and related with many macroscopic properties and performances, with molecular simulations. This book presents our understanding about it. Thereby, a simply and new way to readily understand energetic materials is expected to be paved, based on this book. It contains energetic molecular crystals, energetic ionic crystals, energetic atomic crystals, energetic metallic crystals and energetic mixed-type crystals and the substructures closest to crystal packing. Meanwhile, the common intermolecular interactions in energetic crystals will be introduced. In addition, theoretical and simulation methods for treating the intrinsic structures will be briefed, as they are the main tools to reveal the molecules and crystals. Besides, the polymorphism as a level of intrinsic structures will be briefly discussed. In the final of this book, we introduce the crystal engineering of energetic materials. This book features the first proposal of intrinsic structure and crystal engineering of energetic materials and the understanding of the properties and performances of energetic materials by maintaining a concept that structure determines property. It helps to promote the rationality in creating new energetic materials, rather than increase experience.Par Bernhard Rembold. 2023

accident: a cylinder with lenses at both ends. Galileo's Telescope tells the story of how an ingenious optical device evolved from a toy-like curiosity into a precision scientific instrument, all in a few years. In transcending the limits of human vision, the telescope transformed humanity's view of itself and knowledge of the cosmos. Galileo plays a leading-but by no means solo-part in this riveting tale. He shares the stage with mathematicians, astronomers, and theologians from Paolo Sarpi to Johannes Kepler and Cardinal Bellarmine, sovereigns such as Rudolph II and James I, as well as craftsmen, courtiers, poets, and painters. Starting in the Netherlands, where a spectacle-maker created a spyglass with the modest magnifying power of three, the telescope spread like technological wildfire to Venice, Rome, Prague, Paris, London, and ultimately India and China. Galileo's celestial discoveries-hundreds of stars previously invisible to the naked eye, lunar mountains, and moons orbiting Jupiter-were announced to the world in his revolutionary treatise Sidereus Nuncius. Combining science, politics, religion, and the arts, Galileo's Telescope rewrites the early history of a world-shattering innovation whose visual power ultimately came to embody meanings far beyond the science of the stars.
