Well, I'm not quite sure what I should say and what not, but I'm about 30 years old somewhat sick man who is trying to keep himself alive against cancer and depression. Math has been my hobby since 2001. I've also studied theoretical physics, mathematics and astronomy in university about 7 years - before I had to stop due to several reasons. Thus far I'm nothing but a hobbyist when it comes to anything related to my studies.

I have several topics which I'm interested in. Bolded are maybe the main topics.

- In mathematics:
- calculus
**numerical analysis**- differential equations
- discrete systems like difference equations, cellular automaton, etc.

- In physics:
**classical mechanics**: e.g. projectile motion, Hamiltonian mechanics- fluid dynamics
- general relativity
- electrodynamics
- magnetohydrodynamics

- in astronomy:
**celestial mechanics**- stellar physics
- star formation
