What do scientists compare time to?

What is time.

I asked the doctor what time was, and the doctor said that time is life;

I asked the workers what time was, and the workers said that time is money;

I asked the farmer what time was, and the farmer said that time is the fruit;

I asked the scientist what time is, and the scientist said that time is the truth;

I asked the teacher what time is, and the teacher said that time is knowledge;

I asked the lazy what the time was, and the lazy man stood still, couldn't.

Because he didn't know what time was, and time didn't bring him anything.

Resources.

The scientist-based time machine slows down time.

He developed a time machine.

Soviet scientists have slowed down time.

Time is life, time is speed, time is power. Scientists with great creativity and contributions,

Time doesn't exist when you're busy, and when you realize the concept of time, you're waiting.

The analogy about time is as follows:1. Time is like flowing water, never returned; Time flies like a galloping horse.

2. Time is like delicate water in a sponge, as long as you are willing to squeeze it, there is always it.

3. The carving knife of time is always ruthlessly engraved on our faces.

4. Time is like an arrow off the string, time passes by in a hurry like flowing water, and time is like a running horse, passing in a blink of an eye.

5. Time is like sunlight that can be seen but cannot be touched.

6. Time is like the sun in the sun, it can bring us incomparable warmth and light.

7. Time is like a stream of water, it can help us dilute the painful memories in our hearts.

8. Time passes quietly like fine sand in an hourglass.

9. Time is like light, shining brightly, but there is nowhere to look for it.

10. Time passes like flowing water, and everything never repeats.

11. Time is like a clear spring, it can help us wash away the dirt on our souls.

12. Time is like an idle person, always tirelessly moving forward.

16. Time is like a watery sponge, no matter how much you squeeze it, you will always have it.

17. Time flies by like an arrow off the string.

1. Time is like a glass of water, it can dilute the memories of the years. Time is like a mirror, it can reflect all kinds of things in the world. Time is like a leather whip that spurs us to pursue our goals in life.

2. Time is like an underground spring, as long as you dig it, you will find a sweet spring, time is like an oxygen cylinder on the bottom of the sea, if you hesitate too much, it will be exhausted and will be replaced by seawater.

3. Time is like water in a sponge, as long as you are willing to squeeze it, there is always it.

4. Time is like a fresh breeze, blowing across your face, and if you want to touch it again, it has blown away. Time is like the ticking of a clock, you can hear it, but you can't stop it.

5. Time is like a wild horse that has escaped, never looking back. Time passes like water, and nothing happens again.

6. Time is like an arrow off the string, rushing by. Time is like water spilled, gone forever.

7. Time is like the fine sand in the hourglass, passing quietly, time is like a flashing meteor, fleeting, time is like a kind old man, seeing the vicissitudes of the world in a smile.

8. Time is like the golden sand in your hand, no matter how tight you catch, it will always leak, time is like a watery sponge, no matter how much you squeeze, you will always have, time is like the long river of history, no matter how far you run, there will always be traces, time is like a bamboo sieve of the years, what is left depends on your grasp.

1. Time is like an oxygen cylinder on the bottom of the sea, if you hesitate too much, it will run out and will be replaced by seawater.

2. Only cover time is like spilled water, gone forever.

3. Time is like a glass of water, it can dilute the memories of the years.

4. Time is like a mirror, it can make the mountains blind and reflect the world.

5. Time is like a leather whip, which can spur us to chase the goal of life.

7. Time is like the golden sand in your hand, no matter how tight you catch, it will always slip away.

8. Time is like a watery sponge, no matter how much you squeeze it, you will always have it.

9. Time rushes by like an arrow off the string.

10. Time is like a wild horse that has escaped and never looks back.

11.Time passes like water, and nothing happens again.

12.Time is like a spring underground, if you dig it, you will find a sweet spring.

13.Time is like a breeze in the sky, blowing across your face, and if you want to touch it again, it has blown away.

14.Time is like the ticking of a clock, you can hear it, but you can't stop it.

15.Time is like a carving knife, always mercilessly engraved with the vicissitudes of life on our faces.

In the eyes of scientists, astronomers, physicists, etc., the requirements for time are particularly precise because the requirements for studying the speed of light in the universe to detect space and distance are very high. For example, three million years is one second. Chinese"Tiangong-2"It carried an experiment called the Space Cold Atomic Clock, which had an accuracy of one part per trillion.

In the 20th century, a great genius appeared, a man named Albert Einstein. He changed our understanding of science, and even our understanding of the world, and the biggest change in his understanding of us was time. For example, he believes that time is not the same everywhere, but has to do with the environment, with the speed at which people move.

For example, suppose that in the future humans build a spaceship that is close to the speed of light, and then you take that spacecraft and leave the ground for 10 million years, you are still alive because only a year has passed for you. When you return to Earth, you find that everything has changed. Your friends are long gone.

This is called the relativity of time. Does time exist? Why does the passage of time sometimes be slow?

How have scientists and ordinary people understood and defined time, both physical and general, since ancient times? Can we go back in time? Humanity's understanding of time has a long history.

At the beginning of the agricultural era, the concept of the day and year was derived from the calculation of the rise and setting of the sun, the full and waning of the moon, and the alternation of the seasons.

The ancients invented primitive timekeeping tools such as sundials, hourglasses, and water clocks, which we can see in ancient palaces. A sunset is a shadow cast by sunlight on a hand that moves one block for an hour. Sunglasses and water clocks are more precise than sundials.

Water clocks use water droplets to push an internal mechanism that moves like the hands of our watches to keep time, but they are still not precise enough. Around the 16th century, when people started sailing, they got lost at sea, they didn't know where they were, and they didn't know what time it was, so time was very important to them, they needed to measure time accurately, define time.

Some even offer high bonuses to scientists to solve this problem and create a timer for four minutes a week. It is said that Galileo also saw the bounty notice, and he was attracted by the huge prize, believing that if he solved the problem, he would achieve a lifetime of wealth and freedom. From then on, he began to think hard.

Time should be the study of physics, as well as astronomy, mainly every day, which is the time in the eyes of scientists.

Time is an immutable movement, and in the eyes of many scientists, time is also the unity of the universe, encompassing the vast scope of the universe.

Time is like an hourglass, it is constantly lost, and as long as it is lost, it cannot be retained, time flies very quickly, and it is gone forever.

The hour is like an hourglass, constantly lost, and as long as it dissipates, it cannot be kept, and the hour passes very quickly, never to return.
