"Philosophy is written in the universe, a big book that is always unfolding before our eyes. Only when we learn and are familiar with its writing language and symbols can we understand this book. It is written in mathematical language, and the letters are geometric figures such as triangles and circles. Without these, humans can't even read a word. " -Galileo Galilei.

"It was a sunny Sunday afternoon and I went out for a walk. From the gate at the end of Charlotte Street, I came to the grassland and walked past the old laundry. I was still thinking about the steam engine. Then I came to the shepherd's hut. Then it suddenly occurred to me that steam can rush into a vacuum because it is an elastic substance. If the cylinder is connected to the exhaust container, the steam will suddenly rush into the container, and the steam can condense in the container without cooling the cylinder! When these are mature in my mind, I have not walked the golf course. " watt
"After thinking for a long time about the suspicious parts of traditional mathematics in studying various celestial movements, I am angry that philosophers can't put forward the correct theory about the beautiful and orderly cosmic mechanism created by the creator for us. ..... Therefore, I took pains to reread all the philosophical works I could get to see if there was any hypothesis different from the mathematical school of celestial motion. As a result, in Cicero's works, I found that Cicero truly described the movement of the earth. Later, in Plutarch's works, I saw that others agreed with similar views ... which inspired me to start thinking about the movement of the earth. Although this view seems ridiculous, predecessors can imagine circular motion at will to explain the starry sky phenomenon, so I can try to see if it is better to assume that the earth has some motion than to assume that the celestial sphere rotates. " So, from the perspective of the earth's movement, after long-term repeated observation, I finally found that if the movements of other planets are considered in connection with the earth's movement and calculated according to the orbital ratio of each planet, not only can we get all kinds of observation phenomena, but also the orbits of all stars are organically related to the size and order of the celestial sphere and the celestial sphere itself, so that no part can be changed without causing confusion between the stars and the universe. "-"on the rotation of the celestial sphere ",Mikolaj Copernic.
"People are paying attention to an astronomer who suddenly made a fortune, trying to prove that the earth is turning, not the sun, moon and stars. .....
