Born and live in Celje, Southwestern Lower Styria, Slovenia. For a short period I had studied physics and astronomy at the University of Ljubljana and after that I had changed the studies to mechanical engineering at the University of Maribor. At present I am a CAD designer in a die (tool making) sheet metal industry.

Partial chaotically ordered set of my interests in the English version of Wikipedia are listed bellow but, since I am participating here, I must say, my interests have grown to very high altitudes almost from a nowhere-land. I would like to believe I know something, but most probably I might be wrong. I am glad to hear that JAnez Demšar was spending 2 years on physics at UL where he learned some mathematics as he wouln't learn it otherwise at other universities or elsewhere in some SF novel for instance. After that he became a FRIar. Numbers are like children as they say. Our civilization|universe is young, so there is a vast amount of time. Or is it? Let me give here one Solomon Lefschetz's quote

Don't come to me with your pretty proofs. We don't bother with that baby stuff around here.

which tells me much.

1. Anyone is free to find two non-existent terms in the above list. A reward is two dark ales at Smash's pub what is about 4€ (a meek variation of Paul Erdös' reward on Collatz conjecture: mathematics is not yet ready but its lovers are). In fact there are three ones, but the third one does not count...
2. I wonder if this project is worthy enough to "cawt" much of the precious time in it. It may happen in some next 500 years the Wikipedia would look totally different as it is at present. But I shout this won't happen as it is meant to be...
