Hi all,
next week's group meeting will take place on *Tuesday* at 4pm. Joseph
Emerson from the University of Waterloo will be visiting and give a short
presentation.
Additionally, on Wednesday at 11am in E41.1 Chiara Marletto from the
University of Oxford will give a talk entitled "The Constructor Theory of
Information". See the abstract below:
"Constructor theory is a new mode of explanation, where theories of physics
are expressed solely in terms of which transformations of physical systems
are possible and which are impossible. In this seminar I explain how it can
be applied to address fundamental problems in physics, particularly those
related to 'information'. The Constructor Theory of Information is a theory
of information expressed entirely in constructor-theoretic terms. It
proposes conjectured laws of physics that are directly about information.
Indeed, it does not regard the latter as an a priori mathematical or
logical concept, but as something whose nature and properties are
determined by the laws of physics alone. The constructor-theoretic approach
allows one to cure the circularity at the foundations of existing
information theory (namely that information and distinguishability are each
defined in terms of the other); and to explain the relationship between
classical and quantum information, revealing the single,
constructor-theoretic property that underlies the most distinctive
phenomena associated with the latter."
Best,
