English, the common language of science

English is the common language of science. A paper written in English is more valuable than that in Japanese. Someone says that it is unfair. But I think this is a rule. Although science is built on equalities, we need a common language. English is suitable for it because many kinds of people can speak English. English may be easier than Japanese and Chinese. We, Japanese, are not good at English. However, if we want to show something truly, it is not so difficult to do it. The enthusiasm to want to explain something is most important, in which case, languages are not so important.
