Write a short letter asking Copernicus to publish his ideas so everyone can read them.Write a short letter
asking Copernicus
to publish his ideas so everyone can read themPractice One possible version:
Dear Nicolaus Copernicus,I am a student studying astronomy and I would very much like to read your new theory about the solar system. I hope you will publish it for several reasons.I understand the problems with the present theory. The way the planets move is not what you would expectif the earth was the center of the universe. It is also odd that the brightness of some stars seems to change. So I agree with you that we need a new theory. So I hope you will feel you can publish your new theory.
Yours sincerely, Lin QiI know your observations have been very carefully carried out over many years. I know you worry about what will happen if you publish your new theory. No matter how people oppose it, time will show if your ideas are right or wrong.
