My real name isSiim Ainsaar. I was born onAugust 19,1986 inTallinn,Estonia. My home is inSaku (the centre ofSaku Parish). Coming from Tallinn Secondary Science School (Tallinna Reaalkool inEstonian) and, till the 9th form, Saku Gymnasium (Saku Gümnaasium), I am now studying physics inTartu University (Tartu Ülikool). Therefore please apologize my occasional lack of wikitime.

I am interested inphysics (mostly theoretical, but not exclusively),mathematics and also in otherscience subjects. I used to take part in many olympiads every year. In2004 I reached theinternational level by getting a bronze medal on theInternational Physics Olympiad inPohang,South Korea. In2005 I got another one fromSalamanca,Spain. Now I'm specializing to particle physics and cosmology.

My other interests include:

• Rubik's cube andPyraminx
• Cycling (just for my own pleasure, no competitions)
• Orienteering
• Karate (Shotokan style in particular, I have an orange belt or 7kyu)
• Juggling with 3 balls
• Classical music
• Music theory, in particular classicalharmony
• Singing in achamber choir
• Western concert flute (studied for 8 years)
• Piano (5 years of studies and endless improvizations thereafter)
• Harmonica
• And of coursecomputer (since early 1990s):
  • Linux operating system,Gentoo Linux in particular
  • Bash shell scripting
  • C++ programming language
  • LaTeX document formatting system
  • GNU Lilypond music typesetting program
  • Functional programming, in particularHaskell
  • Maxima andMathematica computer algebra programs
  • … and naturallyWikipedia!

I have been using Wikipedia since2004, choosing the username for a personal reason.This edit on23 January2005 was my thousandth. Usually, when I've not dived into the endless information labyrinth, I reside at themathematics andscience reference desks. Browsing the article space, I tend to immediately correct any small mistake I meet, especially regarding TeX and orthography. If I find anything I cannot fix, but seems to need attention, I tag it. Thus,my edits are mostly minor.

• Some general statistics about my edits,
• created articles,
• created redirects,
• created categories,
• uploaded images in Commons (plusthat one now moved there).

• A discussion atWP:RD/Math about the number of permutations with at least one 2-cycle
• Another one about${\displaystyle O(n\log n)}$ evaluation of a polynomial of degree${\displaystyle n}$ and its${\displaystyle n}$ derivatives at some point
• Solvedthis,this andthis nonlinear 2nd-order differential equation
• Found aclosed form expression for continued fraction [1;2,1,3,1,4,1,5,…]
