Discussion:
If you were Nicolaus Copernicus, would you have hidden your theory for so many years? Why? As a scientist, Copernicus was more cautious

than coward. If he had published his ideas at his
time, he would have been killed just as Bruno who

was burnt to death because his theory was against
the Christian Church’s. Every time when a new idea appears, there are always rejections. It’s normal.

Scientists should have patience to spread their truth.

◆ As a scientist, one should be brave. But Copernicus was afraid of being attacked by the Christian Church. So he had hidden his theory for so many years. What do you think of this? Agree: 1.He was cautious. if he had published his ideas, he would have been killed just as Bruno who was burned to death because his theory was against the Christian Church. 2.Every time when a new idea appears, there are always rejections. It’s normal. Scientists should have patience to spread their truth. 3.It made no sense for him to publish his theory in a hurry. He was just cautious not coward. He should protect himself first.

Disagree:
1.Copernicus was very coward. He should speak out his discovery and let the world know the truth earlier. 2.Science can never advance unless people have the courage of their beliefs. 3.As a scientist, you must have the courage to publish your findings. No matter how people oppose them, time will show if your ideas are right or wrong.

Dear Nicolaus Copernicus,

Write a short letter asking Copernicus (not) to publish his ideas so everyone can read them

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 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.

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,
Lin Qi
