I study mathematics and computer science, and I'm starting to learn japanese.
Could you suggest me dictionaries/sites/etc where I could learn terminology on
these subjects?

question
resources terminology dictionary computing mathematics
Japanese dictionary for mathematics/computer science jargon
I have been using [JquickTrans](http://www.postmeta.com/) dictionary software
for years (had to pay $15 before but it's freeware now), and it has a few
specialized dictionary catalogs that could be useful to find science and math
terms:

[EDICT](http://www.edrdg.org/cgi-bin/wwwjdic/wwwjdic?1C) (which is the corpus
JquickTrans apparently uses) has several special dictionaries for technical
terms. The "Computing/Telecomms" dictionary includes such wonderful words as:

変数設定 【へんすうせってい】 (n) variable initialization  
参照渡し 【さんしょうわたし】 (n) call by reference  
オブジェクト[指向]{しこう}プログラミング (n) object-oriented programming

I don't know about math, but at my company, (where i am the only english
speaker) everyone understands the katakana versions of the english words
without even knowing english. If you come to japan though, there are actually
tons of Japanese dictionaries specifically for programming terms.

It is a little bit informal, but the language site that I always use to look
up some word in Japanese is [alc.co.jp](http://eow.alc.co.jp)

It uses the Eijiro dictionary, and has pretty good coverage on many subjects.

Hope this helps.

If you are not a computer nerd, but want to know academically, I think
[岩波数学辞典](http://www.amazon.co.jp/%E5%B2%A9%E6%B3%A2%E6%95%B0%E5%AD%A6%E8%BE%9E%E5%85%B8-%E6%97%A5%E6%9C%AC%E6%95%B0%E5%AD%A6%E4%BC%9A/dp/4000803093)
is the standard for mathematics.

I always check [Weblio's dictionary](http://ejje.weblio.jp/) for a lot of
great real-world examples of technical terms. I haven't looked into what the
sources are exactly, but they seem to have a lot of technical corpora that I
haven't seen anywhere else.
