Time and tide must wait

Time and tide wait for none. Once the word of mouth and the arrow of the bow run away, it never comes back. There are so many types it's hard to say. But these are ancient ideas. The present age is the age of science. These ancient ideas can be disproved by experiments. We will give that.

1. The tube from which you take out the toothpaste can no longer be inserted into that tube. I do it often. I took out more paste. Then hold the mouth of the tube in the paste. I keep inflating the tube with gentle pressure. The toothpaste falls into the tube.

2. An arrow shot from a bow can never be brought back. There is no reason not to go. How far will the bow go? Anyone can run and pick up the arrow. If any child hits the boy, he will be able to run and bring it back every time he throws an arrow. This is a joke at the moment. One Japanese, one American and another Bengali are traveling on the launch and chatting. The Japanese threw a watch into the river and said, "We have a lot of clocks in our country."

"We have a lot of dollars," said the American, throwing ড 100 into the water.
The Bangladeshi threw a boy into the water. "There are a lot of people in our country," he said.
After a while, the boy dived and picked up the watch and the dollar and got on the launch.

3. Time and the current of the river do not wait for anyone. If you want to do it.
Come on time first. It used to be thought that time was running out. But after Einstein's Theory of Relativity we know that time is actually relative. Time does not flow in the same way all over the world. In Stephen Hawking's A Brief History of Time, one of the twin boys was placed on the beach, the other on the top of a hill. As can be seen after many years, the age of the two boys has changed. Because, the speed of time also varies with the height. "It's not a myth," Hawking said. When a signal is sent from a satellite, the time at each altitude is calculated at the same speed.
Isaac Asimov has a science fiction. Once Shakespeare rode in the time machine and moved to the present world. He enrolled in an English literature class at a university. Shakespeare was being taught in that class.

Shakespeare entered that class. He takes classes like an obedient student. Then test. Shakespeare also participated in the experiment and he failed that experiment.

So time does not wait for anyone, it is not right. It is also not true that light always goes straight like a straight line. When light passes by a large planet, the light is bent by the pull of that planet. Einstein said it. That said, this turn can be seen during solar eclipses. His words have been proven true. Scientists have traveled to South Africa on the day of the solar eclipse to prove that the light bends.
Now let's come to the words 'the current of the river does not wait for anyone'. The current of the river waits as soon as the dam is built.

I have seen a few rivers like this. The river is flowing into the sea. The height of the river and the height of the sea are not the same. So we're going by ship. The ship was first anchored in a canal. Then the mouth of the canal was closed. Then the water level of that canal rises and becomes equal to the sea. Then the mouth of the canal was opened. So people can change the course of the river if they want. You can book or stop the flow of the river as you wish.
It depends on your ability. If you have the power, you must be able to control the flow of the river.

4. Cannonballs can no longer be brought back. This is also not true. Earlier in the day, people were tied to cannons and shot, which was a terrible punishment. So it depends on what the bullet is made of. We know that rubber bullets from toy guns can be fired repeatedly. So if the cannonball can be made reusable, then the cannonball can also be used again.

5. The words that run out of the mouth can no longer be brought back.
It also depends on your ability. If you have the power, you can say one thing in the morning and another in the afternoon. No problem. Again, if you are powerless, then what is the value of your words.

Let me tell you a joke.

Police from three countries were given training. At the end of the training, the police were told, ‘Go, catch the deer from the forest.’ The Japanese police caught a deer in an hour. Two hours later, American police brought in 500 deer. And the police of the third country caught a goat and brought it two days later.
‘What’s the matter? Why bring goats? Bring deer. '

‘Just let the wire be remanded. I will admit to myself that he is a deer. '
‘It took two days to bring? "Hey, I caught it two days ago, but I'll show Sean's arrest today ..." If you are in power, you can move the words you want. And if you are a victim of power, then you have to accept what the people in power say. The words that come out of the mouth can also be swallowed. There is no difficulty. But if Chinese scientists are told, they will make this device, where the words that come out of the mouth can be deleted, can be brought back.

One last piece of advice: don't leave what you can do today for tomorrow. There will always be a day after tomorrow.

Thank you.....
