   It even works with two digons sharing their boundaries. Or two unigons. Or, perversely, it works with a single vertex and a single face. The face has no sides. (Think of a sphere with a single vertex on it.)

   Or he might understand it as an organ stop. The 5 1⁄3′ (quint) and 4' (octave) stops just create constant parallels. The prohibition of parallel perfect intervals is for independence of distinct voices, which strengthens counterpoint.

   For the first, I frequently (for my own projects) change the Array prototype to have Array.prototype.toString = function () { return '[' + this.join(', ') + ']'; }; It would be convenient if Ob

   Javascript is a lot saner than that. The result is "12". (I'm ok with automatic casting so long as it's an embedding. Every number has a reasonable string representation, but not vice versa. Wanting explicit casts like

   Yeah, and putting a natural measure on the space of rectangles, squares are a measure-zero subset. In other words there are so many rectangles, almost no rectangles are squares.

   One reason people care about knots in low-dimensional topology is that every compact ("finite-volume") 3-dimensional manifold without boundary can be constructed by taking a 3-sphere (the set of points in R^4 unit distance from th

   Yeah, it's pretty cool! On one hand you have knot traces, which are spaces that completely determine whether a knot is slice, and on the other you have the Rassmussen s-invariant, which can sometimes tell whether a knot isn't sli

   This is definitely her field. Pretty much every individual topic in the paper was present at the conference mentioned in the acknowledgments, either during a talk or at the coffee breaks (not all put together, of course). I don't thi

    Is it apt comparing being right about things to a broken clock? Unlike a clock, there's no guarantee that anyone might eventually be right about anything. Sure, a monkey at a typewriter will eventually produce Shakespeare's comp

    I agree, but I'm saying something stronger here. The reaction notation is equivalent to a FRACTRAN program. Given a prime<->species correspondence, it survives a round trip to and from fractional notation, so to speak ("

    I'd call the reaction notation pseudocode inasmuch as I'd call assembly language pseudocode or prime factorizations pseudocode -- they're equivalent in completely mechanical way. (Caveat: there needs to be a prime<->sp

    I've played with some programs I made to explore 4D objects, and, yes, you do gain some intuition. Interestingly, I was told one of George Boole's daughters got lessons from a guy on 4D objects by using colored wooden blocks. She

    Adding to that, even just six frequencies to choose from would let you have twenty distinct targets. (Six choose three.)

    I can see the similarity, though Git seems like an interesting differentiating example. Technically, it is extremely simple. A commit is a file tree with content stored in blobs along with a reference to the previous commit. A branch is the

    I'm vaguely remembering a talk I saw at Microsoft Research in 2013 by someone who studies psychoacoustics at a university I can't recall. They created an acoustic model that predicted certain qualities of a sound (wetness, harshne

    It makes certain kinds of representation theory easier to deal with. Rather than just group homomorphisms to automorphisms of a vector space (or ring homomorphisms to endomorphisms of a vector space) you can more generally study functors fr

    I don't think so, because the simulation uses vortex particles with continuous positions. Sure, time is discretized, but space is not, like how grid-based methods are.

    A while back I was learning about doing high quality approximate fluid simulations. If you take the curl of the Navier-Stokes equation and quantize (perhaps not the right word), you can simulate a collection of vortex particles that generat

    No, they can't, since they are just representations of the knot diagram. As for uniqueness, even "rational knots," the ones from the simplest of the fundamental polyhedra, have multiple fractions representing them.

    That's known in Haskell as the List monad. There's a function to transform Maybe (like Rust's Option) to lists. In Haskell, lists can be infinitely long. Regarding the IO monad, Simon Peyton Jones has an article explaining w

    The set membership symbol is called a lunate epsilon. As I half remember, someone used the Greek version of the first letter of the Latin word "est," meaning "is."
