Download Description

The decomposition of a beam of light can be noticed by exposing it to a prism. If, in a dark room, a beam of light be admitted through a small hole in a shutter, it will form a white round spot upon the place where it falls. If a triangular prism of glass be placed on the inside of the dark room, so that the beam of light falls upon it, it no longer has the same direction, nor does it form a round spot, but an oblong painted image of seven colors--red, orange, yellow, green, blue, indigo, and violet. This is called the solar spectrum. ... Read more

Book Description

The key technology for future information processing and communication systems is light wave manipulation. Optical fibers and all optical switching devices have already been intensively developed, mostly based on inorganic materials. From the viewpoints of response time and materials processing, organic materials are more attractive. Although much work has been done following these lines the outlook until now has not been favorable due to the lack of stability of organic materials. Among various kinds of organic materials, nonlinear optically active materials are most promising for light wave manipulation. The study group of 'Light Wave Manipulation using Organic Nonlinear Optical Materials' was organized in 1995 under the support of The Ministry of Education as a priority research project and it has made remarkable progress in this field. This study group brings together an unique combination of chemists, physicists and electrical (device oriented), and consists of three groups investigating wavele ... Read more

Little Mouse's Learn and Play Colors
My daughter and I loved this book. It helped her learn colors and to pick out objects out of the picture. She and I really enjoyed reading it. We would love to have a copy of it. The one we have came from the library and needs to be returned. I hope I win the $50 Gift certificate so I can buy this book for her. She will be surprised greatly. I also will check into the other 3 books in this series if I win. I can't wait to find out. We really love these books. Courtney always wants to read them. They are the only ones she really enjoys. Thanks for the opportunity to win. Tina Wine ... Read more

Leonid Sokoletsky, Bar-Ilan University, Israel
I think this is excellent book for those who want to have an understanding of complicated, but marvelously beautiful world of optics. The book is vast on questions considered - from relatively simple geometric optics to extremely difficult radiative transfer equations and multi-layered particle optics, from bio-optics to planetary optics and remote sensing problems. The book has written on the clear simple English and following from audibly described theory to engineering formulae and references on programming codes. I know that now the secondEdition of this book is in preparing. I urgently recommend to read this book to beginning students-optics and professionals dealing with optical methods in their practice. ... Read more

Book Description

Building on the success of his previous two books in this series, 'The Lit Environment' sees Derek Phillips approaching the topic of exterior lighting. This book addresses the issues raised by the perception of light experienced by people who are outside buildings. It is not simply about floodlighting buildings, but takes a more embracing approach to deal with light for the whole external environment.

Covers a comprehensive range of buildings, through 30 international case studies, including buildings in Britain, France, Germany, Denmark, Israel, Egypt and the United States. The book represents a strong fusion of science and quantity with light and vision. Visually inclined designers should understand how science can improve their vision and engineers with a strong science basis should understand how they can come to terms with visual affects. This book illustrates the essence of how to light buildings well.

* Benefit from the experience and knowledge of a top architect and lighting engineer
* Gain an understanding of the design principles involved with this comprehensive overview of exterior lighting
* International case studies from Lyon to Tel Aviv as well as the United States show theory in practice ... Read more
