Sample writing 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 expect if the earth was the centre 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. I know your observations have been very carefully carried out over many years. Now you must have the courage to publish them. Science can never advance unless people have the courage of their beliefs. 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. So I hope you will feel you can publish your new theory. Yours sincerely, (your name) Homework1.
