Mathematical Visualization is a young new discipline. It offers efficient visualization tools to the classical subjects of mathematics, and applies mathematical techniques to problems in computer graphics and scientific visualization. Originally, it started in the interdisciplinary area of differential geometry, numerical mathematics, and computer graphics. In recent years, the methods developed have found important applications. The current volume is the quintessence of an international workshop in September 1997 in Berlin, focusing on recent developments in this emerging area. Experts present selected research work on new algorithms for visualization problems, describe the application and experiments in geometry, and develop new numerical or computer graphical techniques.

Government's ever-increasing participation in communication processes, Mark Yudof argues, threatens key democratic values that the First Amendment was designed to protect. Government control over the exchange of ideas and information would be inconsistent with citizen autonomy, informed consent, and a balanced and mutually responsive relationship between citizens and their government. Yet the danger of government dominance must be weighed against the necessary role of government in furthering democratic values by proposing and promotion policies and by disseminating information and educating citizens. Restraints on government's ability to control communications processes are desirable, but excessive or inappropriate restrictions threaten democracy. Professor Yudof identifies a number of formal and informal checks on government as disseminator, withholder, and controller of ideas and information. Where more controls are needed, the strengthening of pluralism and legislative oversight is generally the answer. Constitutional redress in the courts should be sought only in extreme instances, he cautions, to avoid judicial interference with legitimate policy objectives.

Reprint of sole edition. Originally published: New York: Harper Brothers Publishers, [1948]. "Dr. Meiklejohn, in a book which greatly needed writing, has thought through anew the foundations and structure of our theory of free speech . . . he rejects all compromise. He reexamines the fundamental principles of Justice Holmes' theory of free speech and finds it wanting because, as he views it, under the Holmes doctrine speech is not free enough. In these few pages, Holmes meets an adversary worthy of him . . . Meiklejohn in his own way writes a prose as piercing as Holmes, and as a foremost American philosopher, the reach of his culture is as great . . . this is the most dangerous assault which the Holmes position has ever borne." --JOHN P. FRANK, Texas Law Review 27:405-412. ALEXANDER MEIKLEJOHN [1872-1964] was dean of Brown University from 1901-1913, when he became president of Amherst College. In 1923 Meiklejohn moved to the University of Wisconsin- Madison, where he set up an experimental college. He was a longtime member of the National Committee of the American Civil Liberties Union. In 1945 he was a United States delegate to the charter meeting of UNESCO in London. Lectureships have been named for him at Brown University and at the University of Wisconsin. He was awarded the Presidential Medal of Freedom in 1963.
