English however is currently the most prominent international language so writing in it has a lot of practical advantages.
I prefer to write my research papers in english language. On the other hand I’ve always liked the English tongue as it has a large vocabulary and its grammar allows a wide variety of options.
I only use my native languaje (Spanish) for papers with local results. I write the papers dealing with neotropical topics usually in English, because more people can read your paper and use your results.
I would write all my research papers in English to be able to be internationally understood however, I would write in my mother tongue (Malay or Bahasa Malaysia) if needed.
I write my publications in English because my Iraqi and Arabic language skills are more limited. More importantly, not many people in my field would understand me.
It is not so much a matter of preference. The international scientific bodies need to be in touch and communicate together for the advancement of their disciplines. The language of communication between the members of various scientific and professional speech communities is presently Globish (global English). Because of language spread privilege, which is the result of the sociopolitical dominance of English speaking countries , the scientists have no other alternative but to publish their works in English. Despite objections under what is called linguistic imperialism, English is now used as the main medium for the dissemination of knowledge across the world.
If the journal u are sending your paper to is in English is better to write it in English even from the scratch...For example if ur mother language is Arabic writing in the same format will definetly distort the infomation conveyed.
I prefer to write my papers in English. This language is global and allows researches to be shared and accessible to many scientists around the world. This allows science to develop. RG scientists can communicate and share their research. It can also create international research groups which develop cooperation and knowledge. Just as the universe is illuminated by the sun, man - from knowledge. And knowledge is spread globally quickly and accessible through the papers and books written in English.
I want to ask you: If would Grigory Perelman published his brilliant proofs not in English but in Russian, then they would not be recognized, would that be so? I think that the value of scientific work should not depend on the language on which it was written. If you want, you can always use Google Translator to understand any information. This is not a problem at this time. It is quite another matter when the journal has its own requirements, which must be observed, otherwise the article will not be published. However, if you would, for example, presented not an article but a development (some device) in your own language, then people will buy your development for the fact that it can solve your problems. Thus, language can not become an obstacle to the exchange of information, it is a myth. Another thing - live communication. Here, of course, English is irreplaceable. Although mathematicians, too, should not have any problem, because they can always understand each other in the language of formulas. It is well known that mathematics is not a science, but a universal language.
thanks all for your valuable answers. I agree with all the mentioned reasons for writing in English. I just have the feeling that writing in English makes our research applicable and widely shared but what about our local people who do not speak English?
Most of the international journals are published in English so I need to write research in English. But .... the Arabic language is very rich language ... I have publications in this great language too
I prefer to write my papers in English since it is used as a global 'Lingua Franca' and it is spoken by around 2 billion people, native and non-native together.
