Dana Scott on the History of Lambda Calculus

Includes an interesting anecdote about Church and Turing's working relationship.

He has a real gift for getting to the point in simple terms. Listen to his description of Post-Turing machines at 21 minutes 38 seconds.

This more detailed talk was given almost a year ago in Switzerland:

See Journal of Applied Logic Special issue on Combining Probability and Logic to Solve Philosophical Problems.

Then listen to this:


 See Logic and also Measuring Ignorance.

David Hestenes - Tutorial on Geometric Calculus

Image
This is a very high-level overview, and not too technical, for the first fifteen minutes at least. It's about the relationship between mathematics and physics and development of scientific ideas. At 40:11 he shows how Structure and Interpretation of Classical Mechanics should have been written!

David Turner Obituary by Sarah Nicholas Fri 24 Nov 2023

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory Illinois. Did

Modeling Probability Distributions and Solving Differential Equations

See  Spread Polynomials : 27:48 On factorization of spread-polynomials, see  Lewis Carroll - Crocodile Story Subscribe to Norman Wildberger . JPL Orbits & Ephemerides: https://ssd.jpl.nasa.gov/orbits.html See also this very impressive student project, which is a digital orrery that uses the JPL Ephemerides: https://www.robots.ox.ac.uk/~mjc/Papers/3YP_Report.pdf  This seems to be the basis for a way to make a space-flight simulator for planets. See  Trying to Make a Sci-Fi Movie  for the context. See also  Laplace Transform : Algebraic construction The Laplace transform can be alternatively defined in a purely algebraic manner by applying a field of fractions construction to the convolution ring of functions on the positive half-line. The resulting space of abstract operators is exactly equivalent to Laplace space, but in this construction the forward and reverse transforms never need to be explicitly defined (avoiding the related difficulties with proving convergence).  Mikusiński
