He discovered that objects in water are lifted up by a force that helps them float.

79. Charles Darwin (1808-1882) British
author of The Origin of Species

90. Copernicus’ Revolutionary Theory
Why didn’t Copernicus publish his theory before he died?

91. Read the passage and find the experiences of Copernicus
Birth: February 19, 1473
Death: May 24, 1543
Place of Birth: Toruń, Poland
Career:
Studied mathematics at Kraków Academy
1496 Went to Italy to study astronomy and law at the University of Bologna
1497 Began observations of the Sun, Moon, and planets
1514 Wrote Commentariolus, an outline of his astronomical ideas, but did not circulate it widely
1543 Published De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial)

92. More Information About Copernicus …

93. 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.

94. Writing
Now write a short letter asking Copernicus to publish his idea so everyone can read them.

95. Learning tips
This article is persuasive writing, which is about changing somebody else’s point of view. When you are doing this kind of writing, you must always have some evidence to support your idea. To make this easier, you can hold discussions with your family and friends. Give your ideas and reasons to them whenever you are making choices. You may argue with them and try to persuade them. Then you will find it easier to do your persuade writing.
However, when you are writing, do not forget to plan your work and put your ideas in a logical order.
Now please discuss in a group of four and decide how to write this letter. You can read the tips given to you in ex.3 on page 7

96. First you need to collect your ideas, for example
He believes his new theory is true.
There are problems with the present theory.
He has done many years of observations to prove his new theory is true.
Science can’t develop unless people publish their ideas.
Time will show if his theory is true or not.

97. Here is a plan:
Beginning: Tell Copernicus who you are and why you want him to publish his ideas.
Paragraph 1: Reason 1 and evidence.
Paragraph 2: Reason 2 and evidence.
Summing up: Ask him to think again about publishing his ideas.

98. 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)
