JAMES TAGG

Truphone

James Tagg is a computer scientist, physicist and inventor. He has many patents in the field of human-computer interaction, most notably touchscreen technology and is founder of Truphone, a London based mobile telecommunications company.

James’ talk will begin with the 1989 book The Emperors New Mind by Sir Roger Penrose which argued that conscious understanding requires a non-computational, i.e. non-algorithmic, explanation. Penrose cited ‘Fermat’s last theorem’ as an example of a single problem of infinite nature that is not susceptible to brute force algorithmic solution. At the time of writing it was not known whether this problem was non-computable nor if it could be solved. In 1982 Yuri Matiyasevich showed it was non-computable and 1995 Andrew Wiles proved Fermat’s last theorem, resulting in a paradox. For those who believe the human mind is a computer Wiles had just solved a provably non-computable problem. The paradox is much contested. Arguments are put forth that only general-purpose computers are forbidden from solving any problem and that humans are special-purpose computers solving a specific problem or, alternatively that computers are only forbidden from giving precise answers but approximations are permitted. Tagg will address the concept of non-computability, analyze and refute counter arguments to the Wiles Paradox, and discuss implications for progress in Artificial Intelligence. If non-computability is a significant factor, what are the broader implications on physics and cosmology?
