The inner structure of time
Based on the idea that time is computation, we discuss one interpretation regarding the inner structure of time that explains quantum superposition.

LJ calculus with stoup: A pedagogical approach
We prove a theorem in calculus LJ and in LJT (LJ with stoup) as well. We show that while there are many proofs to one single theorem in LJ, there is exactly one proof in LJT.

Categories in symbols
An introduction to the language of category theory is presented in a very minimalistic fashion, using the fewest number of symbols as possible. In this white paper, the focus is on the main concepts underlying categories.

Lyapunov exponents for the Lorentz transformations
[microresearch]
We calculate the Lyapunov exponents of the complex stretch factor $f^-(z)=(1-z^2)^{-1/2}$ from the Lorentz transformations and of its reciprocal $f^+(z)=(1-z^2)^{+1/2}$ as well.

Time is a discrete dynamical system
We conjecture that quantum vacuum operates its discrete dynamics in a superposition of a class of iterating functions such that each physical system operates within a distinct function.

Two non-isomorphic structures with the same number of elements
[white paper: pedagogical]
For pedagogical purposes, we define a simple language to show that two different structures with the same number of elements in their universes are not isomorphic.
