basic physics

Physics and chemistry courses were usually not taught in the first year of junior high school. They usually started to learn these two subjects in the second or third year of junior high school. Therefore, there was no content related to the basic knowledge of physics and chemistry in the first year of junior high school.

Alright, here are some basic physics problems in junior high school and the corresponding physicists and their corresponding inventions: What is Newton's first law? A: Newton's first law states that any object will remain stationary or move in a straight line at a constant speed without the effect of an external force. Physicist: Isaac Newton The discoverer of Newton's first law was the British scientist Isaac Newton. 2 What is electricity? A: Electricity is a physical phenomenon that can be expressed as the interaction between electric charges. Physicist: Isaac Hendrikse [Description: Coulomb's law states that the interaction force between two electric charges is inverse proportional to the square of the distance between them.] 3 What is a magnetic field? A: Magnetic fields are generated by electric currents and can be expressed as the surrounding magnetic field around magnetic objects. Physicist: John James Clerk Maxwell [Description: Maxwell's equations describe the laws of motion of the electromagnetic field, including Ampere's law and the Farady's law of electromagnetic induction.] What is the reflection of light? A: When light shines on the surface of an object, part of the light will be reflected back, and the other part will penetrate the object and enter the air. Physicist: Aristotle [Creation: The law of light reflection proposed by aristotle.] What is electromagnetic wave? A: Electromagnetic waves are a kind of physical medium that will not be weakened during transmission. They can be expressed as radio waves, microwave, infrared rays, visible light, and so on. Physics: Maxwell [Description: Maxwell's equations describe the law of electromagnetic wave transmission.] 6 What is heat? A: Heat is a physical phenomenon that can be expressed as a change in the temperature of an object. Physicist: John Wallis The law of heat transfer states that the speed at which heat is transferred from a high-temperature object to a low-temperature object is inverse to the temperature of the object. 7 What is pressure?

In " The Three-Body Problem ", there was no clear answer to the question of why the Three-Body Man wanted to kill the basic physics scientists on Earth, but it could be considered from the plot and logic of the novel. In the novel, the trisomatics were described as a highly civilized alien creature with powerful technology and the ability to understand human thoughts. When facing the scientists on Earth, the Three-Body People showed a strange fear and hostility. They believed that the scientists on Earth would threaten the survival of the Three-Body People. Therefore, they tried to kill the fundamental physics scientists on Earth to eliminate this potential threat. In addition, the novel also mentioned that the existence of the Three-Body People on Earth was affected by some factors that forced them to come to Earth and attack humans. Therefore, killing the basic physics scientists on Earth might be a means for the Trisolaris to try to eliminate the influence of this factor. It should be noted that the plot in the novel was fictional and not a real historical event. Therefore, the plot in the novel should be viewed rationally and not as a reference to reality.

Cartoon physics can often be more fantastical and over-the-top, making it seem stronger. However, anime also has its moments of intense and creative physics, so it's not a clear-cut answer. It all comes down to the specific shows and their creative directions.

During the ancient Greek era, a mathematician and physicist named Eulerian proposed the famous Eulerian formula, which was e^ix=cos(x)+isin(x). This formula was widely used in physics and mathematics. The proposal of the eulerian formula also marked a revolution in the history of physics. It allowed people to use mathematical methods to describe and predict natural phenomena. There was also a famous physics story that happened to Newton, a British physicist in the 18th century. When Newton was studying optical problems, he discovered the relationship between the speed of light and the optical path. The ratio of the optical path to the speed of light was a constant. This constant was called the constant in the Michelson-Morley experiment, namely the speed of light. Newton's discovery had an important impact on the development of modern physics. It provided a way for people to describe the transmission of light. These stories are only a part of the history of physics. There are many other important events and discoveries, such as Leibniz's calculus and the law of universal gravitation, Einstein's theory of relativity and quantum mechanics, which have a profound impact on the development of modern physics.

In the United States, there was the American High School Physics Photographer Competition (Aapt), which was organized by the American Association of Physics Teachers. The contestants had to take a photo that could subtly reflect profound physical phenomena and physical principles. The photo could be a natural scene in life or a specially designed scene, and then accompanied by a physical explanation of no more than 250 words (English). The competition was divided into natural photos (photos that naturally appear in daily life and contain physical principles) and design photos (photos that are artificially designed to show specific physical concepts). The photos were required to express physical phenomena and principles. They could be photos taken of natural or creative phenomena. They should be less than 250 words to describe the physical phenomenon expressed in the photos, and each photo should have a title. The photos should be high-resolution and could be clearly enlarged to the size of 10 inches (at least 8 million pixels). The entries must be original works and could not be synthesized by computer or photoshopped. In terms of scoring criteria, the ASDAN China office would select 100 highest-scoring works (50 nature and 50 design) from the photos received and send them to the Aapt Association for a semi-finals (60% of the scores were based on the physical phenomena reflected in the photos, and 40% were based on the corresponding text descriptions in the photos). The Aapt Association would then further select the final winner. The participants were Grade 9 - 12 students (Grade 10 - 12 high school students; GCSE1- A2 are suitable). The registration fee for the competition was 180 yuan per piece of work. There were different awards in the competition, including the top three in the nature and design category in the China region, the top three in the global competition, and the top 50 in the national competition. All contestants would receive a certificate of participation, and the winners would receive a certificate of the corresponding award. In 2019 - 2020, due to the impact of the new crown epidemic, Aapt officials had canceled the competition. The specific competition time for 2020 - 2021 was not announced at that time, so you need to pay attention to the official website. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

'Physics Cultivation' was a concept that appeared in online literature. Some novels set the protagonist as a physicist or someone with a physics background to enter the world of cultivation. For example, the protagonist in " Physics Cultivation ", Chen Pan, was the disciple of a great physicist in the 40th century. He transmigrated to the world of cultivation in an experimental accident. In the settings of such works, physics concepts were often used to explain some phenomena in the world of cultivation. For example, reiki was interpreted as the basic energy of the universe, and ascension was interpreted as crossing from a low-energy region to a high-energy region or from a low-energy universe to a high-energy universe. It also involved the integration of physics theories such as vacuum zero-point energy and string theory with the concept of immortal cultivation. In addition, some novels, such as The Great Immortal Sect of Science and Technology and The Academy of Cultivation Sciences, also involved the elements of combining science and technology with cultivation. They indirectly reflected the creative idea of integrating scientific thinking into the cultivation system. "If you don't have money, why cultivate immortality?" The novel is equally exciting.

At present, there was no complete physics book that could cover all the contents of physics. Physics was an extremely large knowledge system that included many different branches such as mechanics, electromagnetism, energetics, quantum mechanics, relativity, and so on. Even in the same field, different scholars might have different views and explanations. Therefore, even the best physics books could not cover everything in physics. However, there are many excellent physics textbooks and works that provide in-depth explanations of the basic principles and important concepts of physics and cover many different disciplines. If you are interested in physics, you can read these textbooks and works to expand your knowledge.
