    > The Halting Problem is famously only undecidable if the code you're analyzing is being modeled on a "Turing machine" or something equally "powerful" to it. The Halting Problem ap…

    > It does not. That only means that you if you, say, want to analyze how a program behaves when ran in a computer with 16 GB of state, you need to analyze it on a computer that has…

    > Now, I'm not a computer scientist nor a mathematician or logician. So I could be wrong. If so, I would be interested in knowing how I'm wrong, as I've never seen this issue being…

    > Some numbers in a set called the "smooth reals" square to 0... without being zero. This seems to create a universe in which every geometric object is "infinitesimally straight". …

    One "application" (in quotes because honestly for all the fanfare I haven't come across something that was worked out to be usable by non-specialists) is automatic differentiation,…

    The remarks on computable and continuous functions can also be thought about as follows. The law of the excluded middle is only one non-constructive aspect of classical mathematics…

    Originally, categories arose as (mathematical) descriptions of various universes of functions. For example, there is universe of functions that are given linear functions (i.e. mat…

    History is a convenient and readily available proxy for shifting content focus away from mathematical facts and toward mathematical processes such as problem-solving, proof-writing…

    The UI confuses me to the point of frustration. 1. A "Previous" button would help since otherwise you have to go loop through the whole thing to see what actually happened (e.g. ho…

    I'm puzzled by your comment, especially the first few sentences. What did you not understand from her blog post? What kind of evidence would help you understand? What would you ask…

    You've correctly shown that "f2 does not contain p". However, the subtle bit of reasoning "f2 cannot be evenly divisible by p as that would require it to have a prime factor of p" …
