  1. We see the fundamental theorem of arithmetic and the sieve of Eratosthenes in the decomposition into weight × level + jump of natural numbers. Applied to prime numbers this decomposition leads to a new classification of primes.

  6. Street Photography Taxonomy

    Street photography is something that bothers me, so I want to understand it. And to understand things, I need to classify them and understand how they relate. Call it professional bias.

    With street photography, I quickly hit a wall: the term clearly covers many disparate activities and everybody h

  10. My first, favorite and most important sequence, the weights of prime numbers: A117078
    We see prime numbers classified by level and by weight on the graph.

    A117078: a(n) is the smallest k such that prime(n+1) = prime(n) + (prime(n) mod k), or 0 if no such k exists ➡️ oeis.org/A117078

  15. Now we have evidence that #prototaxites are not part of the #fungi kingdom, as they are clearly chemically distinct. Pointing towards them not being a genus, but belonging to their own distinct kingdom. The #classification of #life is fascinating, and an exciting endeavour.
