    Lawvere is the Yoda of category theory

    John Baez is the real-life Yoda though

    obviously Grothendieck is the real-life Dumbledore

    Timelapse of Wood Cut Millimeter by Millimeter Creates Waves that Ripple Like Water [VIDEO]

    this is only a 2+1 dimensional spacetime but i think the first gif sheds some light on the relativistic perspective that what look like different velocities through space are really just different angles in spacetime

  11. Classical mathematics are founded within set theory, but sets don’t have symmetries. We conjecture that if we allow sets with symmetries, then many problems such as Mirror symmetry or Homological mirror symmetry can be explained. One way to do this is to embed sets to higher categories and especially into higher groupoids as already envisioned by Grothendieck, and more recently by Voevodsky. We simply outline this idea in these notes.

    this is a really nice (and short) article

    one of my favorite things about it is that the author uses “thhe” to mean what he calls “the homotopy version of ‘the’”, i.e. to designate something as being unique up to homotopy
