  Hi, I would love to get any hints about the mystery creature cards "Genderwurfstern", "Toothless dancing", "Void Chicken", "Angry As Fuck", "spectre of communism", "The One Ring (ID6A30)", "Toothless", "Das kleine Gespenst", "Kirby", "Pocket Blahaj", "HRT", "The One Ring(IDE8B3)" and "Caronicorn". If you know anything about these cards or perhaps even carry one of them around with you, please visit me at the adult ball pit on floor 0 (near the lost&found) between 13:00 and 15:00 on day 4 (30.12.). I can give tips about at least 2 cards in exchange without having to get up :D

  Hi!

  I'm looking for other Mathematicians who would like to discuss, learn or help me with my thesis project. It's in computational neuroscience, so I'm doing data-driven optimization and numerical simulations of biologically plausible brain models.

  If you are familiar with Time-Continuous Dynamical Systems, Measure Driven Dfiferential Equations, Bifurcation Analysis and/or Numerical Methods related to these concepts, especially Continuation Methods, please get in touch! I'm also interested in, but know almost nothing about Graph Theory and Stochastic Calculus.

  I'm 30 cis-male, slightly on the spectrum, good at listening and very happy to connect on a cognitive level.
