Physical science papers 700 words
As a branch of natural science, physical science has played an important role in promoting the progress of material civilization and deepening human understanding of nature, and has also had an indispensable impact on the development of human thinking. With the development of science and technology and the progress of society, physics has penetrated into all fields of human life.
When it comes to physics, some students find it difficult; Speaking of physics pedants, some students feel unfathomable. Speaking of physicists, some students feel that they are not mortal. It is true that there are only a handful of people who become physicists, but as long as you are diligent in observation, good at thinking, and brave in practice and innovation, you will find that physics is around you. As Marx said: "Science is experimental science, and science lies in arranging perceptual materials in a rational way."
Galileo, an Italian physicist, is diligent in observation. He is interested in the swing of the copper chandelier hanging in the air of Pisa Cathedral. Later, after repeated observation and research, he invented the isochronous polarity of the pendulum. In order to understand the nature of God's anger, Franklin, an American physicist who is brave in practice, risked his life and used an ordinary kite to lower the "fire of God" on a stormy day and invented the lightning rod. Henry, an innovative British scientist. Achar went to the post office to handle affairs. At that time, a foreigner took out a large edition of new stamps and prepared to cut them and post them on the envelope. However, he didn't have a knife and asked Aga to borrow it. Neither did Aga. The foreigner had a brainwave, took off the pin on the suit and tie, neatly tied a circle of small holes around the stamp, and then neatly tore off the stamp. After the foreigners left, Achar invented the stamp punching machine, and the stamps with tooth patterns were born. Archimedes discovered Archimedes principle in ancient Greece; German physicist Roentgen discovered X-rays ... There are countless examples of physicists who have made great achievements in studying things around them.
Today, all the amazing technological achievements of mankind are based on the observation and research of scientists around them in their early years. In learning, we should establish scientific consciousness, focus on the overall situation and start from small things. Make constant progress in physics.
