Time Episode II – scientists explain time: the arrow of time (2)
The laws of science do not distinguish between the past and the future. More precisely, as explained earlier, the scientific law remains unchanged under the combined action (or symmetry) of the original works C, P and t. C refers to replacing particles with antiparticles; P means to take the image, so that the left and right are exchanged with each other; T refers to reversing the direction of motion of all particles, that is, reversing the motion). In all normal cases, the scientific laws governing the behavior of objects remain…
Time Episode 1 – scientists explain time (1)
How people’s views on the nature of time have changed for a long time. Until the early 20th century, people believed in absolute time. That is, each event can be called “ Time ” All good clocks are consistent in measuring the time interval between two events. However, the discovery that the speed of light is always the same for any moving observer led to relativity; In the theory of relativity, people must abandon the idea that there is only one absolute time and replace it with his own time…
Foreign scientists found the earliest Aurora records in ancient Chinese books, more than 300 years earlier than Babylon
We have all heard of the aurora. Although few people have seen it, we all know that it is an atmospheric optical phenomenon in the earth’s two poles. It occurs when the charged ion stream (solar wind) emitted by the solar flare strikes the earth and is attracted to the two poles by the earth’s magnetic field line. When these charged ion streams collide with the gas atoms in the earth’s upper atmosphere (thermosphere), they will emit light, That’s why the aurora appears According to an article published on May…
