Find the specific knowledge of relativity and the process of inference

The process of inference is actually cranky--- pure blindness, blindness is genius, blindness is stupidity, the so-called bold assumption - easy, careful verification - difficult, the success rate is very low, if one in 10,000 is confirmed is a huge success, and Einstein actually discovered e=mc2, indicating that energy can be ** in mass, it is really unimaginable, and it has been proved in practice - to create an atomic bomb, hydrogen bomb, etc., so, he became a genius. But the theory of relativity is not all right, and there are many inferences that are blind, and the theory is not completely perfected, such as bending space, giving the universe **, etc., these are hypotheses, there is not enough evidence, but they can be popular in the world, so that everyone can believe that it is true, and we have to wait for future generations to continue to break blindly.

It is recommended that you take a look at Mr. Liang Canbin's set of books on differential geometry and general relativity and his classes**, you will benefit a lot. The specific knowledge and derivation process is not simple. From a geometric point of view, the theory of relativity is very clear.

You don't have a Ph.D. level, even if someone tells you about it, it's hard to understand. However, I can tell you that everything in the theory of relativity is derived from the constant speed of light, that is, the speed of light does not change in any inertial frame, and although the general theory of relativity is far away and profound, it is still extended from the special theory of relativity, so all the sources are to explain the phenomenon of the constant speed of light. You can learn more about the history of physics.

Only Albert Einstein knew about this...

There are not many people in China who really know.

1. The special theory of relativity is a new theory of straight space-time proposed by Albert Einstein in 1905 entitled "On the Electrodynamics of Moving Bodies", which is different from Newton's view of space-time. "Narrow" means that it applies only to inertial frames of reference.

The starting point for this theory is two basic assumptions: the principle of special relativity and the principle of invariance of the speed of light. The central equation of the theory is the Lorentz transform (group) (see Inertial System Coordinate Transformation).

Special relativity predicts some new effects (relativistic effects) that are not found in Newton's classical physics, such as time dilation, length contraction, transverse Doppler effect, mass-velocity relationship, mass-energy relationship, etc.

Special relativity has become one of the foundations of modern physical theory: all microscopic physical theories (such as elementary particle theory) and macroscopic gravitational theories (such as general relativity) meet the requirements of special relativity. These relativistic kinetic theories have been confirmed by many high-precision experiments.

2. The special theory of relativity does not only include a series of inferences such as time dilation, but also includes the transformation of Maxwell's Hertzian equations. Special relativity requires the use of mathematical tools that introduce tensors.

3. Special relativity is an extension of Newton's theory of space-time, and to understand special relativity, it is necessary to understand four-dimensional space-time, and its mathematical form is Minkowski geometric space.

4. The new classification criterion for physical theories is to divide classical and non-classical physics according to whether the theory is deterministic, and non-quantum theories can be called classical or classical theories. In this sense, special relativity is still a classical theory.

1. The theory of relativity was proposed by Albert Einstein, an outstanding physicist in the 20th century. The theory of relativity is a theory about space-time and gravity, which can be divided into special relativity and general relativity according to the different objects of study.

2. The theory of relativity and quantum mechanics brought revolutionary changes to physics, and together they laid the foundation of modern physics. The theory of relativity has greatly changed mankind's "common-sense" concept of the universe and nature, and has put forward new concepts such as "simultaneous relativity", "four-dimensional space-time", and "curved space-time". However, in recent years, there has been a new understanding of the classification of physical theories, which distinguishes classical and non-classical physics according to whether their theories are deterministic, that is, "non-classical = quantum".

In this sense, the theory of relativity remains a classical theory.

3. The special theory of relativity unifies the two systems of Newtonian mechanics and Maxwell's electrodynamics on the basis of the principle of special relativity, and points out that they both obey the principle of special relativity and are covariant to the Lorentz transform, and Newtonian mechanics is just a good approximation of the law of objects in low-speed motion. On the basis of the generalized covariance, the general theory of relativity establishes the relationship between the local inertia length and the universal reference coefficient through the equivalence principle, obtains the generalized covariant form of all physical laws, and establishes the gravitational theory of the generalized covariance, while Newton's gravitational theory is only its first-order approximation.

4. This fundamentally solves the problem that physics was limited to inertial frames in the past, and is logically and reasonably arranged. The theory of relativity rigorously examines the basic concepts of physics, such as time, space, matter, and motion, and gives a scientific and systematic view of space-time and matter, so that physics becomes a perfect scientific system logically.

1. The theory of relativity in a broad sense refers to the discussion of the concept of relativity, the most common concept of relativity is large-small, more-little, more relative to 1,10, relative to 100,10 is less. The theory of relativity is commonly referred to as Einstein's theory of relativity.

2. Einstein's theory of relativity was originally used to explain what happens when the speed of motion is close to the measured speed. Because the velocity is relative, so all kinds of measured velocities are relatively close, so the theory of relativity should have a wider range of use.

3. Einstein's theory of relativity was discovered to explain the reason why the laws of motion of particles moving at high speed close to the speed of light do not conform to Newton's laws, but conform to Lorentz's laws.

4. For this reason, he made two assumptions: the laws of motion in different frames of reference have the same mathematical form; The speed of light is the same in different frames of reference.

5. Special relativity says that there is a relativistic effect in a coherent system.

6. Einstein deduced the results of slow clock, ruler shrinkage, and space bending from the equation, which is different from the traditional definition.

7. Your "simplicity" is relative, even if you know the theory of relativity very well, you can ask everyone to "simple" discussion. This simplicity is not the same concept as the simplicity of elementary school students. It is more useful to understand the concept of relativity than to understand the theory of relativity.
