Government invests in science reseach fields because technology from them can make money someday. It's true and a well known fact.

I am working for imaging analysis technology, especially in biology and medicine. Until last week, I have never came up with the idea like "What is the best software which doctors can use easily and in the end, patients can be happy."
Anyway, writing english is now not so hard;however I want to write about one math equation called identity theorem. This is difficult in English, so maybe some next time.
