Chris Isham - Topos theory in the formulation of theories of physics

Talk given in Oxford in 2008. See David Albert Talking Complete Nonsense. 

You can't see his slides, but the 2008 paper he refers to is `What is a Thing?': A Topos Foundation for Theories of Physics: I. Formal Languages for Physics A. Doering and C.J. Isham.  A review of some work from a decade earlier: Chris Isham and Jeremy Butterfield Some Possible Roles for Topos Theory in Quantum Theory and Quantum Gravity. See also other publications mentioned in nlab.

The term he coined is daseinization. 

1:02:05 "... the most important thing is: how do you construct,..." A model for a bullshit ontology? 

1:03:33 Urs Schreiber on state representations. See The Category Enriched over the Category of Finite Sets, The Finitely Triangulated Manifold and the Magnitude of a Finite Category. 

I think this is how you should look at the epistemological structure of physics. See John Norton on "Landauer's Principle".

A derivative is linearisation, and differential calculus is essentially linear algebra, ...  See  Freya Holmér - Why Can't You Multiply Vectors?  and  Freya Holmér on Continuity of Splines . See also the MIT OCW page:  Matrix Calculus For Machine Learning And Beyond  (Alan Edelman, Steven G. Johnson) Subscribe to The Julia Programming Language . Alan Edelman talking about expressing mathematics as computer code. The idea is that you can use computer languages to communicate mathematical ideas precisely to other people.

Tensor Fields and Simplicial Complexes

Listening to Freya Holmér last night I started to get glimmers of an idea I had long ago about how to represent vector spaces in computational processes using this recursive abstract type :  abstype 'a point = POINT   of {getx :  'a vector,       diff :  'a point -> 'a point,       move :  'a point -> 'a point,       scale : 'a -> 'a point,       proj :  'a point -> 'a} with    fun new i (op +) (op -) (op * ) dot =    let fun self x =  POINT       {getx = x,        move = fn (POINT pr) =>           (self (x + (#getx pr))),        diff = fn (POINT pr) =>          self (x - (#getx pr)),        scale = fn i =>          (self (x * i)),        proj = fn (POINT pr) =>     ...
