Alonzo Church, 92, Theoretist Of the Limits of Mathematics (Quoted without permission from 95Sep05 NYT) Alonzo Church, an eminent contributor to mathematical logic and teacher of a generation of American logicians, died in Hudson, Ohio on Aug. 11. He was 92. Dr. Church's principal achievements lay in extending the work of Kurt Godel on the foundations of mathematics in a direction that bears on modern philosophy and computer science. "If you ask who is the greatest logician of this century, no question it's Godel, but Church was really pre-eminent among American logicians," said Simon B. Kochen, professor of mathematics at Princeton University. Born in Washington in 1903, Dr Church spent most of his professional career at Princeton, where he recieved his Ph.D. in 1927. Two of his most important contributions to mathematical logic are known as Church's thesis and Churche's theorem. Both can be explained in reference to Godel's incompleteness theorem, a cornerstone of modern logic. Godel, a young Czech mathematician in Vienna, showed in 1931 that any consistent system of formal logic powerful enough to express the truths of arithmetic must be incomplete, in the sense that it will contain statements that are true but cannot be proved or disproved using the system itself. This dealt a fatal blow to the program proposed by David Hilbert to develop a method for determining the truth or falsity of any statement in formal logic, and hence of any mathematical statement, however complex.

The Church-Turing Thesis as an Immature Form of the Zuse-Fredkin Thesis (More Arguments in Support of the "Universe as a Cellular Automaton" Idea) ppetrov@digitalphysics.org Abstract: In [ ] we have shown a strong argument in support of the "Universe as a computer" idea. In the current work, we continue our exposition by showing more arguments that reveal why our Universe is not only "some kind of computer", but also a concrete computational model known as a "cellular automaton".

The Zuse-Fredkin thesis explained by the Church-Turing thesis ... Footnotes 1. Introduction This paper is essentially an addition and continuation of the main idea described previously in [ In fact, it will be best if [ ], the current work, and the forthcoming [ ] are read in a rapid succession. These three works may be considered something like a "triad of papers" that essentially describes a single topic, but only with gradually increasing depth of understanding.
