Hello everybody! My name is Jacek, I'm from Poland. I'm working on my PhD thesis on pure mathematics (potential theory, Markov processes), I'm interested in science, art and IT but in my free time I like to present myself as a nature photographer. I was invited to Steemit by @liriel (you would really enjoy her posts!).
I'd like to present some of my photos:
Muscicapa striata
Dryocopi martii
Motacilla flava
