If wanting to read non-English references, then are there translators that work well for science papers?
Based on getting things like google translate to translate technical terms, I have to go with NO.
Works fine for simple language but technical language is a different game.
Even people who claim to be bi-lingual cannot translate technical information. I had this argument once and gave a lady who claimed she could translate anything a paper on stresses and buckling in 3 dimensions which proved she could not. :)
I have done some work translating a paper or two between 2 languages and it is challenging even for an engineer who understands the concepts to make sure what is stated is what is meant.
