2 Nuclear energy makes use of the physical phenomenon that when uranium atoms are fissioned, a small loss of total mass can be converted into energy, based on Einstein's famous equation e mc2. Today, nuclear energy provides 25 percent of the UK's electricity.
3 The Global Positioning System (GPS) is able to accurately position objects down to the meter because of the correction of signals emitted by Earth satellites based on Einstein's theory of relativity.
4 Special relativity, combined with quantum theory, points to the existence of antimatter. Scientists use positrons, or antimatter "electrons," to study brain activity through X-ray tomography.
5 The properties of subatomic particles are a direct result of the theory of relativity, and their existence can explain a variety of phenomena ranging from the properties of chemical elements to the action of magnets.
6 Einstein's research on photons in 1916-1917 laid the groundwork for the discovery of lasers 40 years later. At present, lasers are widely used in a variety of products from *** to laser printers.

RelativityThe theory of relativity is a basic theory about space-time and gravity, mainly founded by Einstein, and is divided into special relativity (special relativity) and general relativity (general relativity).The basic assumptions of the theory of relativity are the principle of invariance of the speed of light, the principle of relativity, and the principle of equivalence. The theory of relativity and quantum mechanics are the two fundamental pillars of modern physics.
Classical mechanics, which laid the foundation of classical physics, is not suitable for objects moving at high speed and objects under microscopic conditions. The theory of relativity solves the problem of high-speed motion; Quantum mechanics solves problems under microscopic subatomic conditions. 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".
Special relativity.
Special relativity is a theory of relativity that is limited to discussing the case of inertial frames. Newton's view of space-time is that space is a straight, isotropic, and point-isotropic three-dimensional space, and that time is a single dimension (and therefore absolute) independent of spaceThe special theory of relativity holds that space and time are not independent of each other, but are a unified four-dimensional space-time whole, and there is no absolute space and time.
In special relativity, space-time as a whole remains flat, isotropic, and point-isotropic, an ideal condition corresponding to a "global inertial frame". The special theory of relativity takes the speed of light in a vacuum as a constant as the basic assumption, and the Lorentz transform can be deduced by combining the principle of special relativity and the properties of space-time mentioned above.
General relativity.
The general theory of relativity is a theory published by Albert Einstein in 1915. Albert Einstein proposed the "equivalence principle", which states that gravitational and inertial forces are equivalent. This principle is based on the equivalence of gravitational mass with inertial mass (experiments have confirmed that the difference between gravitational and inertial mass is still not seen in the range of 10-12 precision).
According to the principle of equivalence, Einstein generalized the principle of special relativity to the principle of general relativity, that is, the form of the laws of physics is invariant in all frames of reference. The equation of motion of the object is the geodesic equation in that frame of reference. The geodesic equation has nothing to do with the inherent properties of the object itself, but only depends on the local geometric properties of space-time.
Gravity is the manifestation of the geometric properties of space-time. The existence of material mass will cause the bending of space-time, in which the object still moves along the shortest distance (i.e., along the geodesic line - in Euclidean space, it is a linear motion), such as the earth's geodesic motion in the curved space-time caused by the sun, which is actually revolving around the sun, causing a gravitational effect. Just as on a curved surface of the earth, if it moves in a straight line, it actually walks around the great circle of the earth's surface.

First, the principle of relativity.
The state of the physical system.
The law of change has nothing to do with the change of these states and the reference to which of the two coordinate systems moving at relative uniform speed to each other is made. Excerpt from "A Brief Introduction to the Special Theory of Relativity".
Principle of relativity.
The laws of physics are the same in all inertial systems. Therefore, any physical experiments done in the inertial frame cannot determine the state of motion of the inertial frame itself. Excerpt from "Handbook of College Physics" Electromagnetism Chapter 10 Special Relativity Basic Principles of Relativity 296 pages Shandong Science and Technology Press, September 1985
Second, any ray of light always moves at a definite velocity c in a "stationary" coordinate system, regardless of whether the ray is emitted by a stationary or moving matter. Excerpt from "A Brief Introduction to the Special Theory of Relativity".
The principle that the speed of light does not change.
The velocity of light in a vacuum measured in either inertial frame is c and is independent of the motion of the light source. Excerpt from "Handbook of College Physics" Electromagnetism Chapter 10 Special Relativity Basic Principles of Relativity 296 pages Shandong Science and Technology Press, September 1985
A very simple example. You stay with a beautiful girl for ten minutes. Ten more minutes with an ugly girl. You clearly feel that the former is shorter than the latter. This is the very simple theory of relativity in life.

Time is a parameter set by humans to express natural processes. It really should, as Newton said, that the uniform passage of time that is not related to other events, and the rest of the time, is not up to the definition. So, time doesn't turn back. There is no time travel.
When we exceed the speed of sound, we will catch up with the sound that the clock made before, that is, we will first hear the bell strike 3 times, report 3 o'clock, then hear the bell strike 2 times, report 2 o'clock, and then hear the bell strike 1 o'clock and report 1 o'clock, which is the phenomenon of time reversal over the speed of sound!

Hello the content of special relativity: the two principles of special relativity 1The principle that the speed of light does not change. ":
The speed of light in a vacuum depends neither on the movement of the light source nor on the movement of the receiver, and in all inertial frames it has the same value. 2.Principle of relativity. ":
The space is homogeneous and isotropic. The time is even. In all inertial frames, the fundamental laws of physics can be written in the same form.
Albert Einstein established the special theory of relativity in 1905 on the basis of the above two basic assumptions (which are slightly different). To date, all the fundamental laws of physics (except gravity) can be based on the special theory of relativity. Lorentz transform.
The moving clock slows down.
Relativity at the same time.
Clocks in different spatial positions cannot have the following relativity at the same time: two events that occur in two places far apart may appear to an observer to occur at the same time; To another observer in a different state of motion, it may have occurred at a different time.
The ruler of the movement is shortened.
Spatiotemporal interval invariance spatiotemporal interval intrinsic time and system"Co-action"The time measured in the inertial frame is called intrinsic time and is denoted by letters. That is, four-dimensional velocity.
Four-dimensional momentum. Mass-energy nexus.
Four-dimensional acceleration.
The law of velocity synthesis of the relativistic nature of the four-dimensional force.
General definition of energy.
Causality is in the special theory of relativity,"At the same time"It is relative. The order of two events with a nullity-like relationship (i.e., no causal relationship can exist) can also be reversed, but the causal relationship is not undermined. Causation is still valid, thank you for adopting!
