Hello Steemians!

My name is Dawid Ratajczyk and I would like to introduce myself :) I know Steemit for some time due to interest in cryptocurrencies, but now I finally decided to write down this text.
I'm from Poland. I am 26 and just one month ago I got master's degree in cognitive sciences and started PhD in this field. I'm interested in human-computer interaction, artificial intelligence, social robotics and also sensory substitution. That stuff in particular, but generally I think it's good to know things and there are no boring topics. It's only the time that limits us to learn them all.

Regarding my activity on Steemit, I sometimes have thoughts, considerations or findings which are not suitable for academic papers but I want to share them. Steemit is probably the best place where I can post it.
Three years ago I got interested in cryptocurrencies thanks to @saunter. And since then I am a huge fan of them. How they will change the world and how much good they can bring is especially exciting. I have recently written an article about blockchain use cases for polish magazine about cryptocurrencies @ilovecryptopl. I know that there's a lot of cryptofans around here, so it's good to be part of Steemit.

In my free time, I am historical reconstructor (XIII century). Playing medieval ages from time to time allows to relax and reconsider present reality. It changes the point of view on our needs and what we should care about. And I like the adrenaline during the swords combats :).

I'm also interested in photography. Now I mostly use old analog Kiev camera. A couple of my shots below.

That's all for now. Thank you for reading!
