Who's Crazy Now?

When a group of evil geniuses and super-villains get together for a quiet weekend at a secluded resort, plotting the world's destruction, what can go wrong? But when the "newby" is found dead and suspected to be a spy, the whole convention is thrown in to an uproar of suspicion, dissension, and distrust. Things only get worse as more corpses are found and even more questions are left unanswered: Who can we trust? Who killed who? And why didn't I kill them first? They are villains after all... Warning: Mild sexual themes. Full Length / Farce / 7m, 7f / 1 Interior Set


The Ray And Wave Theory Of Lenses

Calculations on lens systems are often marred by the unjustifiable use of the small-angle approximation. This book describes in detail how the ray and wave pictures of lens behaviour can be combined and developed into a theory capable of dealing with the large angles encountered in real optical systems. A distinct advantage of this approach is that Fourier optics appears naturally, in a form valid for arbitrarily large angles. The book begins with extensive reviews of geometrical optiks, eikonal functions and the theory of wave propagation. The propagation of waves through lenses is then treated by exploiting the close connection between eikonal function theory and the stationary phase approximation. Aberrations are then discussed, and the book concludes with various applications in lens design and analysis, including chapters on laser beam propagation and diffractive optical elements. Throughout, special emphasis is placed on the intrinsic limitations of lens performance. The many practical insights it contains, as well as the exercises with their solutions, will be of interest to graduate students as well as to anyone working in optical design and engineering.
