There is one historical pattern. Architects of the Middle Ages, when building castles, designed spiral staircases in them. Moreover, in most cases, the direction in which the stairs turned was as follows: if you go up, you turn right, if you go down, you turn left. This was no accident. Why were spiral staircases in castles built this way? answer

When defending a castle from attack, the defenders often took refuge in the towers. In such cases, opponents attacked from bottom to top, i.e. They climbed the spiral staircases, turning right all the time. In this case, the soldier, as a rule, held a shield in his left hand and a sword in his right. Consequently, to protect himself from the castle defenders, he was forced to cover the right side of his body with a shield, which was inconvenient and prevented him from attacking.

Imagine 2 rooms nearby. There are 3 switches in one room, 3 light bulbs in another. The rooms are isolated from each other, that is, you cannot see or hear what is happening in the next room. You are in a room with switches.

When moving to a room with light bulbs, only once establish the correspondence of the light bulbs to the switches, that is, which light bulb is turned off by which switch? tips

Hint 1: The riddle is based on one of the properties of electric current.
Tip 2: The first thing you should do is turn on the 2 switches.
Tip 3: It takes a certain amount of time to actually complete a task.

Answer

When Edison invented the light bulb, he spent a very long time looking for material for the filament, which he could not char, but could not get the desired result. The electric current caused the filaments to heat up and burn out. It is heating that is the property that will help us in our task. The first thing to do is turn on 2 switches, wait 2-3 minutes for the bulb to heat up, then turn off one of the switches. We go into the next room, the burning light bulb corresponds to the switch left in the “on” position, the extinguished light bulb, but warm to the touch, corresponds to the switch that you turned on and then turned off, the third light bulb is the remaining switch.

One man was sentenced to death. But since he was very respected, we decided to give him a chance. He was informed that tomorrow morning he would pull a piece of paper out of a hat in the main square. In the hat there will be 2 pieces of paper with the inscriptions execute and pardon. Whichever one he pulls out will happen. But his ill-wishers did not want to leave him alive and, having bribed the authorities, made sure that there were 2 pieces of paper in the hat, both with the inscription to execute.
Friends of the accused found out about the plot and informed him. However, he told them not to do anything and not to make this conspiracy public.
The next morning he went out to pull out the papers... He put his hand into his hat and then...
As a result, he was pardoned...

What did he do? answer

He quickly ate one piece of paper, leaving the other to execute. He was pardoned.

One wise man was sentenced to death penalty. In those days, executions were carried out quite often, and a special platform was equipped where the sentence could be carried out by any means.
When the sage was brought to execution, the judge gave him the last word. And he said: “If you are in your last word if you tell the truth, we will hang you, and if you tell a lie, we will cut off your head. I promise to keep my promise no matter what.”
At first glance, the sage has no prospects except to die, but the sage thought well and said his words. As a result, the execution was forced to be postponed.

What did the sage say? answer

Something had to be said that would contradict the king's words. He said, “They will cut off my head.” If his head is cut off after this, it means that he told the truth and he should have been hanged. And if you hang him, it means he lied - and his head should have been cut off! The sage spent another forty years in prison and died of old age...

The righteous man, who lived by honor all his life, died and went to heaven.
God met him there and told him: “You have lived your life honestly, and I am giving you the opportunity to look into heaven and hell, and you yourself will choose where you will stay.” To which the righteous man agreed. Where shall we go first, to hell or heaven, God asked? The righteous man replied, “First to hell.” They enter the room. In the middle of the room there is a huge table, in the middle of the table there is a large bowl of food. People are sitting around the table. Everyone has a long spoon. Everyone can easily reach the thicket, but cannot put it in their mouth. The handle of the spoon is much longer than the arm. And all attempts to put food in the mouth, or to intercept the spoon in a different way end in failure. Everyone sits sad and exhausted. "Yes. This is truly hell." - said the righteous man.
“Let's go look at heaven,” said God.
They enter heaven. And what do they see... “The same table, a thicket with food in the middle. People with long spoons."
- The righteous man was surprised and asked God: “How is this possible? It turns out that heaven and hell are the same thing?
- God answered: “Look at the people.”
The righteous man looked at the people. People sat happy and contented. “What’s the matter?” asked the righteous man. And God answered:

What did God answer? answer

People don't feed themselves here, they feed each other.

Here is another confirmation that it is wrong to divide the world into physicists and lyricists. After all, it is precisely the fact that the duration of Beethoven’s Ninth Symphony in the favorite performance of one high-ranking physicist is one hour and fourteen minutes and nine seconds that formed the basis of one purely technical standard.

Which one? answer
