cautious than coward. If he had

It’s normal. Scientists should have
patience to spread their truth.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. Sample writing (P7)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.

Koningsberg is an island and there is a river breaking it into two parts. “Seven Bridges of Konigsberg” and the famous “Euler path”.People wondered if they could walk around the city by crossing the seven bridges without going over any of them twice or going back on himself, but Euler found he couldn’t cross all the seven ones. This is Euler’s puzzle. The first stage in his research is to find the problem that he could cross six of the bridges without going over any of them twice or going back on himself, but he couldn’t cross all seven. How did Euler prepare for his research?The second stage is to think of a
method: He drew a map and used
dots and lines to simplify his analysis.
Trying and observing over and over
again, he found a general rule. It is topology. Euler’s theory is called “The Euler path”, which is expressed like this: If a figure has more than two odd points, you cannot go over it without lifting your pencil from the page or going over a line twice. What are the theories?So the general rule that Euler found is the even points and the odd points .Look at the following pictures:Conclusion
