Indeed, a few minutes after the chicken chop off her head, she "lives". She may even try to run and fly. This is due to the fact that sometimes, losing his head, chicken keeps the brain stem, which is responsible for most of the reflexes.

Life and real science is very prosaic.
The human brain is only 10% - lozh
This misconception There is already almost a century. Fortunately, or maybe, and unfortunately, it is not. These magnetic resonance imaging of the brain demonstrate that a large part of the cerebral cortex actively involved in human life. Proceedings of our head, even when we sleep.

In space there is no gravity - lozh
This misconception seems to blame the popular expression "zero gravity" and "weightlessness". Gravity is everywhere, the force of gravity acts equally on all people. Astronauts in orbit floating in zero gravity just because constantly falling with his ship to Earth. They do so only in a horizontal plane. Gravity decreases with distance, but it will never disappear completely. And, incidentally, it is not true and misleading, that the space vacuum. In fact interstellar space is filled with all sorts of atoms and particles, the distance between them just a bit more than on Earth.

Coin thrown from a skyscraper kill a man - lozh

So if you have decided to deal with his ill-wisher such exotic way, better take a trifle to buy bricks.
The growth of brain cells in the adult stops - lozh
Although the most active human brain grows and passes the basic stages of formation was at an early age, cell division ceases and adults. Studies show that neurons successfully grow and change until his death. So nerves are restored, and the odds are at all smarter.

That cure a cold chicken broth, of course, impossible. But scientists still support adults who force their children to absorb sick chicken broth. In it, the studies show that contains substances with anti-inflammatory properties that help stop the spread of the disease. Therefore, no matter what you think, Mom was right.
Yawn "contagious" - rather pravda
Experience has shown that when one person starts to yawn, it "infects" it all around. It is difficult to say whether this is true from a scientific point of view, but some anthropologists believe that the reflex to repeat the blunders neighbor stayed with us from the apes.

And to see the wall from the moon can not be sure.
The change of seasons is due to changes in the distance of the Earth from the Sun - lozh
Changing the distance from Earth to the sun, what is happening with the movement of the planet in its orbit, it has little effect on the temperature on Earth. It's all in the angle of inclination of the Earth's axis relative to the sun, which, changing affects the change of seasons. It's simple, but it is still not clear.
