Robert MacKay's Chaos Machine. Its configuration space is a genus three surface. The dynamics of the machine are equivalent to geodesic flow on the surface, which is Anosov, hence chaotic.

Let me emphasize this: inmates took advanced math just for fun.

I discovered the board game "Seasons" yesterday: it is very nice! A 2 to 4 players game at the intersection of deck building and resource management with smooth yet interesting gameplay. Not too hard to understand nor too easy to master.

You may call me sentimental, but the variable ζ will always be a root of unity in my heart.

John Baez collects more than you wanted to know about the statistics of random permutations: math.ucr.edu/home/baez/permuta

The really pretty ones are

Part 3 puzzle 8: What is the probability that a chosen element of an \(n\)-element permutation lies in a cycle of length \(k\)?

And part 6 puzzle 7 (don't ask me how the numbering works): What is the expected number of \(k\)-cycles in a random \(n\)-element permutation?

Hi, my name is Max Reinhold Jahnke. I'm 34, and I'm a mathematician from São Carlos, Brazil. The main reason I'm here is to write about my hobbies and connect with new people. I love #mathematics, #reading, #writing, #learning foreign #languages, watching TV shows, and playing video games.

I'm a post-doctoral researcher at the Federal University of São Carlos, and my research field is Partial Differential Equations. I will stop here because I don't want to scare anyone.

I usually read science, fiction, and fantasy. My favorite authors are H.P. Lovecraft, G.R.R. Martin, and V.S. Vinge. Now I'm reading the series The Expansion, and I'm loving it.

As I said, I like to learn foreign languages. Some years ago, I studied a little #Esperanto, but I didn't reach a high level. I can read the Esperanto Wikipedia and some news in Esperanto, but can't speak the language.

I'm always learning. Usually, it is mathematics and languages, but I also like to learn about other cultures, science, and technology. Most recently, I began learning how to bake bread, my main interest is in #baking #sourdough.
