For more than 30 years the book Practical Gear Design, later re-titled Handbook of Practical Gear Design, has been the leading engineering guide and reference on the subject. It is now available again in its most recent edition. The book is a detailed, practical guide and reference to gear technology. The design of all types of gears is covered, from those for small mechanisms to large industrial applications. The presentation is designed for easy reference for those involved in practical gear design, manufacture, applications and problem solving. The text is well illustrated with clear diagrams and photographs. The many tables provide needed reference data in convenient form.
In Rethinking Physics Second Edition, gravity is fully explained and Newton's and Einstein's gravitational concepts are reconciled by considering elementary particles as electromagnetic energy localized in the observer domain. A theoretical expression for Newton's gravitational constant, GN, is derived and a major issue in physics, the Large Number Problem, is logically resolved. The electron and proton are shown to be quantum black holes satisfying the Schwarzschild equation, with charge and mass as emergent properties, and give the proton - electron mass ratio of 1836. The Universe mass energy density is derived, giving a value close to observations. Dark Energy and Dark Matter are briefly discussed.
This book deals with gas-phase nanoparticle synthesis and is intended for researchers and research students in nanomaterials science and engineering, condensed matter physics and chemistry, and aerosol science. Gas-phase nanoparticle synthesis is instrumental to nanotechnology?a field in current focus that raises hopes for environmentally benign, resource-lean manufacturing. Nanoparticles can be produced by many physical, chemical, and even biological routes. Gas-phase synthesis is particularly interesting since one can achieve accurate manufacturing control and hence industrial viability. Nanotechnology is popular today. However, basic scientific aspects of the relevant, underlying processes have not received sufficient attention. This book fills the gap in the current literature by addressing certain fundamentals of gas-phase nanoparticle synthesis. Chapters cover topics such as forces within and dynamics of nanoparticle systems, gas evaporation and deposition, laser assisted...
This updated and expanded third edition of this successful work includes a new, comprehensive introduction to the recursive Green?s function technique applied to model solid state nanostructures. Focusing on the physical background as well as on technical details of the technology, this is a must–have book for beginners in the field.
High Quality Content by WIKIPEDIA articles! In mathematical physics, spacetime algebra is a name for the Clifford algebra C?1,3(R), which can be particularly closely associated with the geometry of special relativity and relativistic spacetime. It is a linear algebra allowing not just vectors, but also directed quantities associated with particular planes (for example: areas, or rotations) or associated with particular (hyper-)volumes to be combined, as well as rotated, reflected, or Lorentz boosted. It is also the natural parent algebra of spinors in special relativity. These properties allow many of the most important equations in physics to be expressed in particularly simple forms; and can be very helpful towards a more geometrical understanding of their meanings.
This clearly explained layman's introduction to quantum physics is an accessible excursion into metaphysics and the meaning of reality. Herbert exposes the quantum world and the scientific and philosophical controversy about its interpretation.
An accessible introduction to the practical aspects of satellite communications. Provides historical background of satellite communications and discusses the wide range of applications throughout the world.
Archimedes was an extraordinary mathematician, astronomer and engineer, credited with astonishing breadth of thought and brilliance of insight. This classic 1897 text celebrates Archimedes' achievements. Part 1 places Archimedes in his historical context and presents his mathematical methods and discoveries, while Part 2 contains translations of his complete known writings.

In cryptography, SIGSALY (also known as the X System, Project X, Ciphony I, and the Green Hornet) was a secure speech system used in World War II for the highest-level Allied communications. It pioneered a number of digital communications concepts, including the first transmission of speech using pulse-code modulation. The name SIGSALY was not an acronym, but a cover name that resembled an acronym -- the SIG part was common in Army Signal Corps names (eg, SIGABA). The prototype was called the "Green Hornet" after the popular radio show The Green Hornet, because it sounded like a buzzing hornet ? resembling the show's theme tune ? to anyone trying to eavesdrop on the conversation.
