PLENARY SPEAKER
JAMES TAGG
Truphone
James Tagg is a computer scientist, physicist and inventor. He has many patents in the field of humancomputer 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 noncomputational, i.e. nonalgorithmic, 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 noncomputable nor if it could be solved. In 1982 Yuri Matiyasevich showed it was noncomputable 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 noncomputable problem. The paradox is much contested. Arguments are put forth that only generalpurpose computers are forbidden from solving any problem and that humans are specialpurpose 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 noncomputability, analyze and refute counter arguments to the Wiles Paradox, and discuss implications for progress in Artificial Intelligence. If noncomputability is a significant factor, what are the broader implications on physics and cosmology?
