Physics thesis

Physics is a natural subject with a long history. As an important branch of natural science, physical science not only plays an important role in promoting the progress of material civilization and deepening human understanding of natural science, but also has an indispensable influence 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.

The rearview mirror outside the driver's cab is a convex mirror. By using the divergent effect of the convex mirror on light and the vertical and narrow characteristics of the virtual image, the real object you see is smaller and the observation range is wider, which ensures the driving safety.

The reflector of automobile headlights is a concave mirror.

It is made by using the property that concave lens can reflect the light from the light source at its focus into parallel light.

The car is equipped with a solar film, so it is difficult for pedestrians to see the faces of people in the car. The solar film can reflect some light and absorb some, so the light penetrating into the car is very weak. To see the passenger's face clearly, it is necessary to radiate enough bald heads from the face to the outside of the glass. Because the light inside the car is weak and there is not enough light to come out, it is difficult to see the passenger's face clearly.

When the front window glass of a car is tilted, it is reflected just like the air above the front, so that the image of the passengers in the car is separated from the pedestrians on the road, and the driver will not have the illusion. The bus is bigger, and the front window is much higher than the car. If the front window is installed vertically, it seems to be at the same height as the window, and pedestrians on the road are unlikely to appear at this height, so drivers will not mix with pedestrians on the road when they meet passengers outside the window.

Now all the amazing scientific and technological achievements of mankind, such as sheep cloning, Internet, nuclear power plants and space technology, are based on the observation and research of trivial things around us by early scientists. In learning, students should establish scientific consciousness, focus on the big picture, start from small things, experience observation, thinking, practice and innovation, gradually master scientific learning methods and train scientific thinking methods, and soon you will have a scientist.
