This is quite a tricky photo. I held my webcam in front of the screen, and it generated such an image. You can see the point of infinity in the photograph. The same phenomena can be observed if two huge glasses are kept facing each other and parallel to each other. The light keeps on getting reflected from each glass and if you put your head in between them, you can see the +infinity and -infinity on either sides. Some people don�t understand this phenomena and consider it quite enigmatic.
Flying Trains, by G.Zelkin, from MIR publications. It is one of the books of the series �SCIENCE FOR EVERY ONE�. The book discusses the development of a number of promising vehicles, such as fast wheel-less trains, and shows the perspectives of their advancement. The material of the book is based on a great deal of facts concerning the latest achievements in the field. It is a nice book intended for those who are interested in the history of transportation, new technical ideas and the prospects of transportation technology.
