Mathematical and Physical Data, Equations, and Rules of Thumb

This is a comprehensive sourcebook of definitions, formulas, units, constants, symbols, conversion factors, and miscellaneous data for use by engineers, technicians, hobbyists, and students. Some information is provided in the fields of mathematics, physics, and chemistry. Lists of symbols are included. Every effort has been made to arrange the material in a logical manner, and to portray the information in concise but fairly rigorous terms. Special attention has been given to the index. It was composed with the goal of making it as easy as possible for you to locate specific definitions, formulas, and data. Feedback concerning this edition is welcome, and suggestions for future editions are encouraged.

Geometry, Topology and Physics

This book is a considerable expansion of lectures I gave at the School of Mathematical and Physical Sciences, University of Sussex during the winter term of 1986. The audience included postgraduate students and faculty members working in particle physics, condensed matter physics and general relativity. The lectures were quite informal and I have tried to keep this informality as much as possible in this book. The proof of a theorem is given only when it is instructive and not very technical; otherwise examples will make the theorem plausible. Many figures will help the reader to obtain concrete images of the subjects.

GEOMETRIC OPTICS

Geometrical optics is both the object of abstract study and a body of knowledge necessary for design and engineering . The subject of geometric optics is small , since so much can be derived from a single principle , that of Fermat , and large since the consequences are infinite and far from obvious . Geometric optics is deceptive in that much that seems simple is loaded with content and implications , as might be suggested by the fact that some of the most basic results required the likes of Newton and Gauss to discover them . Most of what appears complicated seems so because of obscuration with mathematical terminology and excessive abstraction . Since it is so old , geometric optics tends to be taken for granted and treated too casually by those who consider it to be ‘‘understood . ’’ One consequence is that what has been long known can be lost if it is not recirculated by successive generations of textbook authors , who are pressed to fit newer material in a fairly constant number of pages

Design sketching. Including an extensive collectioin of inspiring sketches by 24 students at umea institute of design

Design Sketching (2005, 104 pages, Klara Sjölen and Erik Olofsson) is an innovative sketch technique book that has since its release in 2005 quickly become a bestseller and a highly regarded resource for designers, students and Universities throughout the world. Rather than taking the traditional theoretical approach, its aim is to teach and inspire by displaying a broad collection of design sketches encompassing the entire design process. Twenty-four talented students from the Umeå Institute of Design, one of Europe’s best design schools, have contributed to the diverse material in the book. Design Sketching includes basic theory, investigative and explorative sketches from the early stages of projects, explanatory sketches used to communicate, and persuasive sketches done to sell and express emotion. The book is rounded of with 6 step by step sketching tutorials.

The art of soldering for jewellery makers: Techniques and projects

Jewelry-making involves working with hot metals, cutting tools, and high temperature burners, activities which are potentially hazardous and carried out at your own risk. The guidelines laid down in this book on pages 10–11 on safe working practices and workstations are important, and should be read and followed carefully. Readers should also check their compliance with health and safety legislation currently in force, and always follow manufacturers' instructions, guidelines, and recommendations for using and storing tools and equipment. Inform your insurance company if storing or using combustible gas within or near an insured premises. The publisher accepts no liability for loss or damage sustained in the course of using this book.
