relativity textbook

Label: style blog HTTP Div problem log c EF RToday, when I saw Einstein in his later years, he thought about the theory of relativity and suddenly realized (). The special theory of relativity requires that the speed of light remains unchanged for all inertial references. However, if we use light as the reference (origin ), all inertial systems are on the sphere and tangent to the sphere, which can indeed b

Great artist is better than others. in his Tolle-style cosmic view, the more likely conclusion is that great artists are good for you, just as the book says, "Life is good for people. Appreciation is a good way to avoid argument. The problem is that it is not true. When you start to design things, you will feel this. No matter what people do, they naturally want to do better. football players want to win competitions, and CEOs want to increase revenue. it makes people feel happy and proud to do

resolution; it also includes Xu shaoxia's understanding of this passage. The premise of this passage should first be clarified: C ++ is a static object-oriented language, so there is basically no question about the type of runtime decisions. NaturallyThe contradiction points to: the object type is fixed before compilation, or determined at compilation.. Deerchao does not have to give up this sentence as the basis of his argument because the original post of deerchao is basically centered on thi

The correctness of the mathematical model is obvious, but the premise of the whole problem is not exactly the same as the mathematical model, the mathematical model and the conclusion , such as "he", "Man", "Life", "Live" and "death" can not be precisely defined, "year" Nor is i

have not had the slightest experience.I have told people many times, my ideal of life is, I hope one day to learn the various branches of mathematics, and then stand at a high point, overlooking the whole field of mathematics, really appreciate the beauty of mathematics. However, it is difficult to achieve this. The biggest difficulty is the lack of a way to learn maths. Read the textbook? This is what I want to say today-textbooks are extremely unre

This is what I talked about during the summer vacation. I handed in questions from the physics department. Suppose a person is moving at a close speed of light. Then he looks back and asks what he sees? For a long time, it cannot be solved. The only answer is:Colorful lightBut I don't know why.Is it a magic horse?In the end of the semester, I suddenly remembered it when I was studying for one day. I mentioned it to Zhang Zijun xiaopan.As a result, the two abandoned the operating system and star

classic physical perspective ".The smoothness of time is manifested in the uniformity of the time passage speed. In philosophy, space and time are similar to the above descriptions and conform to the inherent framework of our minds. Our minds naturally think of space as flat, boundless, and irrelevant to any material.. We can call it "Void", but it doesn't mean we can discard this void? No. Although the space in philosophical sense is basically equivalent to vanity, it serves as a stage for all

these people in the last day trial. I will tell you the correct solution: II. Introduction to future technologies: 1. Future Technology tree: The exploration activities of the earth's people on future science and technology are still in a state of unordered and unordered searches without theoretical guidance. Although this status can discover something, it is often just an empirical discipline. For example, if a head shot is about robots, why do we need to study robots? It may not be cl

a measure of its inertia, and vice versa. In real life, we often use this method. For example, the balance says the gravitational mass of an object, but from the result of the call, we immediately know how much inertia the object is. Einstein had very vividly used the gravitational attraction between Earth and Stone as an example to illustrate that gravity and inertia were two physical properties that were completely different. "The earth attracts stones with gravity and has no knowledge of its

Reading notes: "From one to Infinity"This book was found in the beauty of mathematics, the original is an old book in the 80 's, but the scope of the book is quite wide, from digital to infinity, then to four-dimensional space, and then to the theory of relativity, then to the microcosm, and then to the macro-world, some of the content with some simple way to let people understand, with high school knowledge of people can understand, In terms such as

The Austrian physicist Wolfgang Pauli (Wolfgang Pauli) was born in 1900 and died in 1958. A rare genius at the beginning of this century, he has made outstanding contributions to the theory of relativity and quantum mechanics, and was awarded the 1945 Nobel Prize in Physics for discovering the "Pauli incompatibility Principle" (exclusion Principle). This principle, which he discovered in 1924, has revolutionized the establishment of atomic structures

The book's influence is quite large, in the watercress ranking in the first place, in this temptation, I decided to read, unfortunately ... Summary of the bookThe author of this book is the famous Stephen Hawking .... It seems to be the words, God is closing a door, always open another window. Hawking, although physically hindered, but the thinking is no less than ordinary people, but also more than ordinary people.He put forward many well-known theories of physics.This book describes the c

be seen that these physicists, despite their lifelong commitment to science, struggled for it, but this did not affect their lifespan. They are still relatively long, the oldest Newton lived 85 years old (the rest of the ox is holding the money to sleep, can not live long?) )。 2 personality and HobbiesEinstein: 6 years old with his mother to learn to play the violin, 14-year-old stage performance. Love music, like playing the violin for life. History, Geography, language performance is poor, ha

One pixel knowledge 1.1 device pixel (Devices pixel)It is a physical concept, referring to the physical pixels used in the device (physic pixel). This unit is represented by PX, which is a [relative absolute unit] ————That is, on the same device, the physical length (such as inches) represented by each of the 1 device pixels is fixed (that is, the absolute nature of the device pixels);However, between different devices, the physical length (such as inches) represented by each of the 1 device pix
