Warming up 1.Get 1-2 Ss to report to the class information of Copernicus ( Who is he? What achievement did he make? When? ...) 2. Background Nicolaus Copernicus was a Polish astronomer (1473-1543). Born in Torun, he began his university studies in Krakow in 1491, where he studied canon law and Latin and Greek classics. However he also had an interest in mathematics and astronomy. After obtaining his degree of Doctor of Canon Law (教会法规博士学位)in Italy in 1503, Copernicus returned home to Warmia in Poland to serve as Canon (=priest) . In 1530, Copernicus completed his great work De Revolutionibus (《天体运行论》).Copernicus knew that these findings would lead him into trouble with the Roman Catholic Church (罗马天主 教教徒), so he wasin no hurry to publish his theory. He only published it as he lay dying in 1543. Though Copernicus did not live to hear of its extraordinary impact, the book which first

suggested that the Sun, not the Earth, is the centre of the universe is now recognized as one of the most influential scientific works of all time. 3 Get Ss to give the names of the nine planets of 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 certre 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, Zhang Hua Step 4.
