Hello!
I read a bunch of SE's and write on some.
Professionally, I pursue a PhD in mathematics.
As an amateur I do things like to do things like
- Design and play non-standard harmonicas
- Dance bugg (Sort of Swedish jive)
- Juggle
- Talk to people
- Turn everyday things to math problems
I also like reading about and thinking about many different subjects, including
- All kinds of musical instruments
- Human prehistory
- The future of humanity and possible disasters
- ... in particular, risks of artificial intelligence
- Animals and other organisms
- Evolution
