What is time!

In the language of science, what is time?

In the language of science, Aristotle gave a scientific definition of the first (350 BC) period, which is quite modern in relation to his time; He defines time as "the means of calculating motion relative to the past and the future."

In his Principia of 18, Newton wrote, "Absolute, true, and mathematical time, in and of itself and of its own nature, flows uniformly." One 'master clock' is this 'time'

In 1829, the astronomer Jean-Jacques Drt de Myran showed that this 'time' regulates the daily cycle of plants; It used to be thought that plants would respond to sunlight and match their petals, but Myron found that the cycle of the plant remained unchanged even after leaving it in a dark room for several days. That is, he is controlled by something other than sunlight

Then, in 1824, Saadi Karno, while doing mathematical calculations of engine efficiency, gave birth to the second law of thermodynamics and the concept of 'entropy'. According to this formula, the entropy of any closed system always increases From this idea, it is determined that there is a 'direction' of time, that is, time can only move in the direction in which entropy increases.

Thunder struck Einstein in 1905 when he claimed that the universe had no 'master clock' at all, as Newton thought. Rather, how time passes depends on the speed of the observer The only exception to this is the speed of light, which maintains the same speed for everyone That is, in Einstein's theory of relativity, time became secondary, and in its place came the speed of light, a special status, a speed that cannot be exceeded. In 1906, Herman Minkowski, Einstein's teacher and German mathematician, collectively described time and space as "space-time".

Einstein's revolution in science came in 1915 when he said that gravity affects time (and space)! This theory of general relativity gave birth to the 'black hole' whose 'boundary' seems to be 'from afar' as if it is in the eternal future.

The concept of 'direction' became more popular in 1926; The scientist Arthur Eddington explained the direction of time in the formula of entropy: if there is more chaos around, then this direction is towards the future, if there is less chaos, then this direction is towards the past. That is all that can be said in physics.

Another revolution took place in 1929; Astronomers have observed that the farther a star is from Earth, the faster it moves away from us. The 'Big Bang Theory', which says that all the matter and energy around us was concentrated in a very small space at some point in time this is the primitive time of the universe. That is, there is a beginning of time

In 1974, two American scientists, Arno Penzias and Robert Wilson, discovered the "Cosmic Microwave Background" with the help of a radio antenna - the echo of the Big Bang. However, there is disagreement among scientists as to whether time started at the moment of the Big Bang.

There is still a lot to be written about time, but Shiva's song will be sung to make it look like rice I may have already sung it Because I wrote a lot about time, but 'What is time?' Probably I do not know the satisfactory answer.

A dimension?

Speed ​​calculation? Or

Something deeper than that?

Can you answer those questions?

Note: Importance of time-

We know the proverb - Time and treade wait for none. We should use every moment in our life. We should enjoy all the time we got. Becouse every second in our life is gift from our god.

For capture and measure time. Many legends are worked for it. As result we got watch in our hand, phone or wall in our house.
