Scientists could write their science in any of the higher level representation languages, or even Esperanto or Lojban, or whatever they culturally prefer for their particular brand of science. As a bonus, you could even use the Vernacular Metatranslator optimizers to tighten up prose even if it was originally written in your preferred output language!
In most languages, word for word translation produces rubbish. In Esperanto it doesn't.
Esperanto has no particular word order, instead, suffixes denotes parts of speech. This alone makes it much more simple to translate literally between languages. It also has no gender, and is perfectly regular.
The language was designed so that one could send a letter to a friend who with did not speak it, and they could translate the entire document quickly using only a dictionary and a basic understanding of the grammar.
