How is English important for your job or future?

I would like to be a physicist. For realizing my dream, there are some stages on which I should appear.                   The first stage is to write thesises in English. There are meny difficult technical terms or formulas, which is seldom used as usual. And, I have heard a rumor that there seems to be the idea: thesises in the world of science should be written in English. Even if that rumor is not true, I should write what I would like to report to people all over the world in such a way. Lastly, it goes without saying that I will make my English understood. So, in order to be able to write my thesises, I must learn how to use those words and formulas, how to say in English, and how to write thesises in understandable English. The second stage is to make presentations at conferences. After detecting fruits of examinations, I will announce the fruits at conferences, including those that is international. I shouldn't depend on interpreters. I must tell those to other people with my own words and ideas. In order to do so, I must be able to say smoothly what I think or how I think. The third stage is reading and listening to English. Other people will write or tell their ideas in english like what I should do. In my concludion, English and my dream cannot be separate at all.
