Fingers in the socket can not poke. Coffee at night to drink, too. Hands before eating wash sure. Every day we are faced with unwritten rules, which we follow. And I believe the facts known from childhood. But do they deserve our faith? Let's look at the biggest myths of everyday life.
: Quickly lifted it isn't considered "fallen"
There is a "five second rule": if fallen on the floor food fast to raise, it will be quite edible and harmless. In fact, sitting on the floor of the microbes, and the sight of food, they immediately sit on it. This is especially true of the kitchen, where flourishes the bacteria of Salmonella. Do you want to eat off the floor?
: the Acid will burn the skin and disfigure you
In fact, there are hundreds of different acids, and the majority of them are not strong enough to damage the skin. We are regularly consumed several weak acids: acetic and citric. However, some acids can be harmful. Hydrochloric, nitric and sulfuric acid can damage the skin, but the list of strong acids is quite small.
: brain Cells do not regenerate
In fact, recovering. The reason people believe this myth, it's a long confidence scientists that a complex brain to be damaged in the case of the growth of new cells. In 1998, scientists from the Swedish universities and University of California have found that brain cells regenerate. Centers of learning and memory in the brain can create new cells. Later in the Georgia state University stem-cell researcher Steve Stice has discovered a process of making copies of embryonic stem cells that can transform into brain cells.
: Fell from a great height, the coin will kill a man
Not so long ago we wrote about the meteorite that landed in the thigh of a woman. She had a bruise. People believe that if you throw a coin into the man from atop the Empire state building, she will gain enough speed to kill him. But this is not true. Given the aerodynamic nature of the coin and its low weight, the person will remain alive. He will feel the impact, it may be unpleasant, but that's it.
: Lightning never strikes the same place twice
The lightning may strike the same place several times. It happens quite often. In the aforementioned Empire state building it hits 25 times per year, for example. Lightning chooses tall buildings and trees, but in the open field, lightning is more than likely to strike twice in the highest object before you advance far enough in the search for another high goal.
: Evolution means growth from the bottom up
Actually, although natural selection selects more acceptable genes from the gene pool, imperfect organisms feel great. Mosses, fungi, sharks and crabs, for example, remained unchanged for a sufficiently long period of time. Other types has changed, and not always in such a way that the improvement was obvious. To develop to be "in shape" does not mean that the development will progress just be easier to survive and reproduce in a familiar environment.
: the Cold causes colds
In fact, colds are caused by a viral infection in the respiratory tract. Viruses do not appear in your body magically just because you forgot a scarf and mittens. For the most part, we greet with viruses hand when you come in close contact with other people who are already infected, which means you are putting yourself more at risk of getting sick, staying at home with coughing family than if you were wandering around the cold woods without a hat, but one.
: Children's vaccination causes autism
In fact, there is no evidence that the children's vaccination causes autism spectrum disorders. This myth has a clear origin story. In a 1998 article in the prestigious medical journal the Lancet reported that a common vaccine for children may lead to RACES. But first, from this article and refused to apologize, and secondly, there were no scientific papers proving the facts of the article. Despite this, many parents refused to vaccinate their children. Well, Voltaire believed superstition, the worst enemy of the human race.
: Rubber tires protect car from lightning
Actually, the bus does not save a car from a lightning strike. If you get caught in a thunderstorm while driving, of course, inside the machine will be safer than outside. The vehicles provide protection against lightning, but not why you think. When lightning hits the car, it gets in metal frame which protects passengers in the role of a conductor and transferring the charge into the ground. It is logical to assume that a convertible or motorcycle will not protect you from a lightning strike, though they have tires and rubber.
: Children get mad from sugar
In reality, let the kids eat their cookies. The researchers did not find any significant relationship between sugar consumption and hyperactivity. The analysis, published in the journal of the American medical Association, showed that more than 16 qualified scientists are unable to identify a significant link between sugar consumption and cognitive performance or behavior. Of course, the sugar primarily affects obesity (and other problems), so parents still need time to taking children out of cotton candy.
: the Big Bang Theory explains how the universe was created
Actually, the Big Bang theory merely reflects our observations of the early Universe: originally, it has undergone massive and rapid growth that continues to this day. Physicist Joao Magueijo and does protect scientific views on the fact that during the existence of the early Universe the speed of light was greater than it is now (why it is constant and maximum, read here). The Central value of the Big Bang theory is the explanation of the expansion of the Universe, not how it originated. What was before the Big Bang — is another question.
Myth # 12
: Summer the Earth is closer to the Sun
No, no and no again. For people living on the equator this is true is exactly the opposite: the Earth closer to the Sun in January. But for people living in the southern hemisphere January is the best time when you can sunbathe on the beach and drink cold lemonade. What are the reasons for the change of seasons? The proceedings tilt of the Earth's axis. The earth wobbles during rotation. Summer occurs when the earth gets the most direct sunlight; in winter the sun's rays reach the earth under an oblique angle.
: People descended from chimpanzees
In fact, looking at a chimpanzee, you don't look at his grandfather, you see a distant relative. Humans and chimpanzees descended from a common ancestor. 95% of human DNA and chimpanzees are the same, but it talks mostly about how very similar our bodies. At some point, our genetic paths diverged, so humans and chimpanzees began to develop under different genetic codes.
: Antibiotics kill viruses
In fact, antibiotics are a wonderful target poisons that help your body kill bacteria — the bacteria, not viruses. Moreover, the virus generally can't be killed, because he is not alive initially. When malicious cough or cold takes over, we all want to take a pill and get rid of them. Unfortunately, therefore, you cannot fight against the germs that cause colds and flu, and in many cases antibiotics can make the problem worse. Listen to the doctor, do not self-medicate.
: the Full moon drives people crazy
In fact, you will kill during the full moon only in one case: if you are a werewolf. For centuries, nearly all cultures have attributed mystical powers and influence of supernatural beings to the bright and round face of the full moon. In English the word "lunacy" (insanity) and "lunatic" (crazy) originate from the words "lunar" — associated with the moon, of course. But in spite of human prejudice, science finds no significant relationship between the phases of the moon and acts of murder, aggression, madness, vandalism or rituals of human sacrifice.
: After your death, the nails continue to grow
Actually no. Just think: why? The tissues of the body to burn energy from food to continue growth. People do not continue to eat or digest food after death. In addition, in the case of death the heart stops pumping blood. How fingers will get the oxygen needed to sustain life in the tissues and the production of a new keratin? The same applies to hair.
: the Coin on the rails let the train derailed
Well, try it. Freight trains weigh thousands of tons. With such success you can say that will upset a tanker with one firecracker. Trains sometimes don't roll out of and under threat of more massive: cars or rocks. The legs of the myth grow here's how: once many people have tried to align the coin on the rails and suffered severely until death.
: Bats are blind
Thank you, bats see very well. From Chiroderma villosum, for example, have eyes, and those eyes great work. Where did this myth? Like dogs, bats rely heavily on other senses, like hearing and smell. With the help of advanced system of echolocation bats are well oriented in the dark and hunt almost invisible prey. Bats love the night, unlike people who for some reason decided that the eyes of nocturnal hunters perform a rudimentary function.
