Here are some Mathematics...

Hello, this my webpage on Wikipedia. some useful Wiki links (which are very useful to me) as well as a long list of articles to which I have made a major contribution, and which I'm checking once a while.

Area of interests include physics and mathematics (as I am a Master in Physics and Ph.D. in Mathematics), engineering, Gothic architecture, Combat Engineering, IDF Caterpillar D9, counter-terrorism, Gothic literature and philosophy, metal music, Israel and photography - check my Gallery (pictures I've created).

As an Israeli Jew I have added articles about Israel and fixed other articles - which had inaccuracies about Israel (misspelled names, unupdated information etc). Scope of the articles isn't limited to politics and the Israel-Palestinian conflict but also deals with the geography, history, culture, sports and science of Israel.

I am a son to a familiy which lost dear ones in the Holocaust and have seen the horrors of Palestinian terrorism during Police service. I cannot accept any form of Holocaust denial, support of Nazism, Antisemitism toward Jews and denying their right to live safely in their own Jewish state in Israel.

Currently I'm a SysOp in the Hebrew Wikipedia and therefore investing most of my efforts on improving and monitoring the domestic Wikipedia. It is developing very well, with great increase in Sciences (Mathematics and Physics) and Military technology articles. Recently I started a project on Gothic and Neo-Gothic cathedrals and structures in the Hebrew Wikipedia.
