Notes On Categories • 2

Re: Category Theory • Joe Moeller JM: In category theory, we have this perspective that we should focus attention on maps, on the relationships between objects, rather than on the objects themselves.  What’s your favorite examples of people giving a … Continue reading

Logical Graphs • Discussion 3

Re: Peirce List • JFS • RM • ET • RM • JFS • JFS • RM Dear John, Robert, Edwina, The Peirce List discussion on “thinking in diagrams vs thinking in words” called to mind the time I spent … Continue reading

Logical Graphs • Discussion 2

Re: Category Theory • Chad Nester CN: Recently a few of us have been using the “cartesian bicategories of relations” of Carboni and Walters, in particular their string diagrams, as syntax for relations.  The string diagrams in question are more … Continue reading

Logical Graphs • Discussion 1

Re: Laws of Form • John Mingers JM: I find it very frustrating not to be able to draw crosses and expressions within emails or Word documents.  Does anyone know of any software or apps that can do this?  If not, … Continue reading

Inquiry Driven Systems • Discussion 9

Re: Laws of Form • Leon Conrad LC: As someone who has worked on, teaches, and uses the CoI [Calculus of Indications] to make classical syllogistic logic much easier to practice and more visually intuitive than any of the visualisations we … Continue reading

Inquiry Driven Systems • Discussion 8

Re: Category Theory • Simon Burton SB: From what I’ve noticed there are two kinds of mathematical thinking:  manipulating abstract syntax, versus direct experience/perception of concrete mathematics.  These two are intertwined in various ways, but in my experience people generally … Continue reading

Inquiry Driven Systems • Discussion 7

Re: Category Theory • Henry Story HS: I place Logic within Mathematics and modal logic is a field of Logic, and so of mathematics.  You will find that modal logic comes up a lot working with machines, programs, and all … Continue reading

Inquiry Driven Systems • Discussion 6

Re: Category Theory • Henry Story HS: If one were to think about maths and children’s education one would need to look at the needs of other subjects too.  It should be easy for people here to work out how … Continue reading

Differential Logic • 11

Transforms Expanded over Ordinary and Differential Variables As promised in Episode 10, in the next several posts we’ll extend our scope to the full set of boolean functions on two variables and examine how the differential operators and act on that … Continue reading
