Named ordinary things that science can not explain

(ORDO NEWS) — Science is very important in the life of mankind. With its help, you can make existence easier, make progress move forward.

Science helps develop critical thinking. At the same time, there are some things familiar to every person that cannot be explained with the help of science.

The action of paracetamol

Paracetamol or acetaminophen is considered such a common drug in Western countries that no one has thought about exactly how it works.

Nobody knows this, not even scientists. More precisely, they know that it is an effective pain reliever, but the principle of its effect on the body remains unknown.

Most experts suggest that paracetamol blocks neurotransmitters and prostaglandins. These are the substances that give a signal to the brain that a person is in pain.

Some studies have shown that paracetamol can affect the levels of serotonin, the “happiness hormone”. If this is true, then there are new questions and no answers.

Why do people yawn

Everyone yawns quite often. Why is it really needed? Initially, it was believed that yawning allows you to increase the level of oxygen in the body, but in 1987 this version was disproved.

Some time ago another idea was proposed. The air flow can cool the brain and prevent it from falling asleep.

At the same time, yawning may not have any physical effect. Some theories suggest that this is just a psychosocial phenomenon.

Studies have been conducted that partially confirmed this version. In addition, a person will more often “catch” yawns from people he knows.

Why are buttocks needed?

The large berry muscles are considered the largest in the human body. There are several versions of why they are needed.

In the first case, it is said that this is the result of evolution. In order for a person to run fast, he needed anatomical adaptation not only of the muscles, but also of the bones of the buttocks.

The second issue in this situation is fat. Why it is present in the buttocks – no one knows. At the same time, it has been proven that the amount of fat depends on the size of the brain, but this point will continue to be studied.

Why is the bike stable while riding?

Scientists have no idea why a bicycle is stable and does not fall while riding. Initially, there was a gyroscopic theory, but it was refuted 50 years ago.

Then it was considered that stability is affected by the contact angle of the bicycle wheel and the road. This theory was debunked in 2011.
