Chinese composition material daquan junior high school 1 life is dominated by a string of hopes, and hopes have made life. Because a person has hope, life will be explained and life will be meaningful and interesting; Hope is like the sun. With light, there is heat, and with heat, there is vitality. Hope, like a small stream, flows to the rivers, seas and seas of Wang Yang, giving full play to everything in life. A faithful pursuer of hope doesn't know how old age comes from.
Hope is by no means a stingy giver, but it is not a generous Meng Changjun. Sweating is sweating, bleeding is harvesting. It's just that sometimes when you look too close, you dream of getting the light of hope when you take a step. How can there be light without darkness? Without perseverance, how can we succeed one day?
There is a considerable distance from hope to ultimate goal. The bigger the goal of hope, the more tortuous the road, and the more difficulties you will encounter. Therefore, it is necessary to have a strong will, make patient efforts, take heroic steps, and walk non-stop towards the future of hope, so that one day you will taste the taste of hope.
For a long time, the geocentric theory of Ptolemy, an ancient Greek astronomer, has dominated people's thoughts. Ptolemy believed that the earth was motionless at the center, and the sun, moon, planets and stars all revolved around the earth. Copernicus overthrew Ptolemy's theory about the movement of celestial bodies and clarified Heliocentrism: The sun is the center of the universe, and the earth revolves around the sun. Then, Bruno accepted and developed Copernicus' Heliocentrism, who thought that the universe was infinite and the solar system was just a celestial body system in the infinite universe. Galileo observed the celestial bodies through a telescope and found that the surface of the moon is uneven. Jupiter has four satellites, the sun has sunspots, the Milky Way is made up of stars, and Venus and Mercury have profit and loss phenomena. Soon, Kepler analyzed Tycho.
According to Bula's observation data, it is found that the planet runs in an elliptical orbit, and three laws of planetary motion are put forward, which laid the foundation for Newton to discover the law of gravity ... Therefore, it can be said that science is a process of continuous discovery and truth is a process of continuous innovation.
