Answer the phenomenon of

Many people put a hand on the wheel surface. Read the spell and it will . spin. This " strange " game is in the south of our country, considered by many to be mystical. Scientists have experimented and concluded that the rotary is due to . mechanical force, not by any mystical effect.

The phenomenon of rotating wheels

This folk game has appeared in our country for hundreds of years, mainly circulated in some southern provinces (Binh Dinh, Lam Dong, Da Nang .). The rotary has a circular structure, made of wood, copper, aluminum or glass. Wheels are designed on a bearing to reduce friction when rotating. Participants play around, put their hands on the tray and " order " continuously in the head: " Turn " .

Clockwise or anticlockwise rotation is conventionally played by the player when starting the experiment. Players read continuously and when the tray starts to spin (or the feeling of the tray has a tendency to spin), follow the rotation direction of the tray to follow, not to stop. When the tray has turned, everyone wants to stop and read: " stop ". Read continuously until the tray stops and then lift your hand again. Thus, when people put their hands on the tray and read the command, the tray will obey and spin (or stop) in accordance with the mantra that people are reading.

So does the turntable really understand human thoughts?

To find the answer, the Union of Applied Informatics Science and Technology (UIA) has set up a mission to investigate and understand the nature of this phenomenon. According to the initial assessment of the UIA Science Council, the tray can be rotated when and only if there is a force acting on the tray to create the torque - this force is in the plane of the tray, which is perpendicular to the sale. rotating glass (ie tangent to the turning circle).

There are four possible causes for this moment:

- The impact of electromagnetic fields,

- The impact of biological forces,

- The impact of mechanical forces and

- The impact of metaphysical power or spiritual realm.

The survey team chose a famous place for the spinning wheel, the Phong Lan restaurant next to Tau pagoda, Da Lat, where the press talked a lot in the past years. The owner of the restaurant reserved a room to specialize in performing this item.

The rotary wheel is made of wood, placed on a well-designed rotary bearing. The owner introduced this as a " family heirloom " tray, dating back to his grandfather's time, at the same time introducing the visitor's notebook about the magic of the wheel.

First of all, the mission turned the tray out of the rotating shaft, checking to see if it could install devices that could be affected by electromagnetic waves from the remote control. This option was quickly removed because no devices were found, more than a long time ago, the tray was performed like that, but at that time it was not possible to have a remote control device by electromagnetic waves like now. hours. In the test team, there are some famous psychic, they said that they did not find the intervention of the spiritual realm in this room.

Thus, it is possible to eliminate the possibility that the tray is rotating due to the impact of electromagnetic force and the spiritual realm.

Positive test

To conduct a positive test, the team followed the same procedure as the other groups did before: People stood around, placing their hands directly on the surface of the tray and reading commands for " rotating " platters. The first time ordered the tray turning clockwise. After more than 4 minutes of reading "mantra", the tray slowly turned, getting faster and faster. After about 5 minutes, the tray is required to " stop ". The experiment is repeated, but counterclockwise. This time, only about 3 minutes of the wheels have been turned and when you want to stop it takes just over 1 minute.

Negative test

The third experiment, assigned each person to participate in a ball, the size of a ping pong ball. This time, people do not place their hands directly on the surface of the tray, but put their hands through the sphere on the tray. The process of reading " voice commands " remains the same as before. But strangely, people read up to 30 minutes but the tray still didn't budge. Even if you change the "command" to read it, the tray is still impassive.

The landlord was very anxious, saying: " Up to now, there have been no cases where the experiment has not been done. The brothers are the first group to read the mantra, but they will not listen to the words."

Explanation of the phenomenon of rotating wheels

According to Vu The Khanh, a member of UIA's research team, when the player's hand does not come into contact with the tray, it must be indirectly through the sphere, the player can only apply the force perpendicular to the tray (this way). does not cause rotation torque for the tray. Observe carefully the times of the experiment, clearly: the player, whether accidentally or deliberately pushing his hand, the ball immediately rolled immediately, no transmitting force down to the tray anymore. How to put such force has caused the whole "miracle" to end.

Through this experiment, the team concludes that there is no impact of some biological or supernatural forces as people think. In fact, the tray can only be rotated when and only when the player places the hand directly into the tray to create the rotating moment for the tray. If this force is lost due to the rolling ball, the tray cannot be turned.

But where does the mechanical force cause the torque to be?

When players place their hands directly on the surface of the tray, constantly reading the command, the psychology of autism arises, gradually falling into illusion: it seems that there is some invisible force that makes the tray spin and feel The tray "prepares to spin", so players tend to lean towards the conventional rotation in their heads. At that time, accidentally or intentionally increased the force on the tray. Just like that, the tray will spin faster and faster. This is not to mention the case where one of them had intentionally pushed the spinning wheel. The process of stopping the tray also follows that principle, generating the corresponding psychology.

Thus, the phenomenon of rotating wheels is caused by mechanical forces, not a mystical impact at all. In fact, players are not really in the state of "impartial", not really " unconscious ". Therefore, when they read the command, they gradually fell into hallucinations and of course the effect of " self-obsession ". This effect is the culprit causing mechanical force to create a rotating torque for the tray. However, players do not think of themselves as the culprit, they are self-possessed, so when they see the wheels, they think that due to some objective factors.

In the same experiment, the team conducted with those who practically practiced meditation or yoga, the wheels did not rotate (because they created the unconscious state so they were not governed by the effect of " self-obsession"). Marketing ").
