Throughout the world, mysterious patterns have almost magically started appearing in fields--baffling the farmers who own the land and the scientists who examine them. What are these fantastic geometric figures? Who (or what) is creating them? Two journalists specializing in crop circle research provide revealing answers in this bestselling and visually stunning study. A spectacular 30-page pictorial, which presents an eye-catching survey of the contin-uing phenomenon, will fascinate believers and non-believers alike with its surprising beauty, variety, and complexity.
This second edition is a thoroughly revised, updated and expanded version of a classic text, with lots of new material on electronic signal creation, amplification and shaping. It’s still a thorough general introduction, too, to the theory and operation of drift chambers. The topics discussed include the basics of gas ionization, electronic drift and signal creation and discuss in depth the fundamental limits of accuracy and the issue of particle identification.
