Event description

Description

The Department of Informatics Annual Distinguished Lecture with Professor John Tucker (Swansea University)

Computability by people, machines and nature: the legacy of Alan Turing

The event will begin with tea and coffee from 18.00, followed by the lecture, 10 minute Q&A session and will close with a drinks reception.

Abstract
What can and cannot be computed, now or in the future? This modern question has its origins in
philosophy, mathematics, computer science, and other parts of science and engineering. However, different
theoretical answers to this question were discovered and largely unified by 1936, before the first programmable electronic computers appeared. Since 1936, Alan Turing’s discoveries have been at the heart of computability theory, the subject that analyses the scope and limits of computation.

Professor John V Tucker of Swansea University will describe the origins of our contemporary understanding of computation and its theoretical limits, and look at later developments, including: its generalization from computation with bits to computation with arbitrary data; the introduction of criteria for computation to be practically feasible; and new evidence of the power of physical systems to implement computations that break the barriers defined by Turing's theory.
