To help authors with technical and scientific vocabulary, Phillips Publishing is maintaining an Arabic-English-Arabic lexicon of terms, that is the merger of lexicons generated by Phillips authors. Authors are encouraged to review this lexicon whenever they need to translate some concept for which they know the English word.
If they do not find the word they are looking for, they are free to suggest one and include in their publication's lexicon, for subsequent inclusion in the lexicon of Phillips.
If they do find a translation in the lexicon but do not approve of it, they are free to suggest an alternative, which will also be included in the lexicon of Phillips. Subsequent usage will produce natural selection.
An obvious reference for a first attempt at translating technical terms from English to Arabic, is google's translate site.
