Fiction | The biggest myths of everyday life


Stick your fingers in the socket can not be. To drink coffee at night – too. Wash hands carefully before eating. Every day we are faced with the unspoken rules that we follow. And believe facts known since childhood. But are they all deserve our faith? Let’s break down the biggest myths of everyday life.

Myth 1: Fast raised is not “dropped”

There is a “five-second rule”: if the food had fallen to the floor quickly raise, it will be completely edible and harmless. In fact, sitting on the floor of the microbes, and seeing the food, they immediately sit down on it. This is especially true for the kitchen, where a thriving bacteria Salmonella. Do you still want to have sex?


Myth 2: The acid will burn skin and cripple you

In fact, there are hundreds of different acids, and most of them are not strong enough to damage the skin. We regularly consume some weak acids, acetic and citric. However some acids may be harmful. Hydrochloric, nitric and sulfuric acids can damage the skin, but the list of strong acids is quite small.

Myth 3: The brain cells do not regenerate

In fact, restored. The reason that people believe in this myth, it is a long belief of scientists that the complex brain will be damaged if the growth of new cells. In 1998, scientists at the Swedish University of California and found that brain cells regenerate. Centers of learning and memory in the brain can create new cells. Later, at the University of Georgia stem cell researcher Steve Stice found the process of making copies of embryonic stem cells, which can be transformed into brain cells.

Myth 4: The fallen from a great height coin kills a man

Not so long ago we wrote about the meteorite that hit a woman in the thigh. She escaped with bruises. People believe that if you throw a coin into a man with a height of the Empire State Building, she gathers enough speed to kill him. But this is not true. Given the aerodynamic nature of the coin and its low weight, the person is still alive. He will feel the impact, it may be unpleasant, but that’s it.

Myth 5: Lightning does not strike twice in one place

Lightning may well strike the same place more than once. It happens quite often. In the aforementioned Empire State Building it beats 25 times a year, for example. Lightning chooses tall buildings and trees, but in the open field more than likely lightning strike twice in the highest object before you will move far enough to find another high-end.

Myth 6: In space, no gravity

In fact, in the space full of gravity. That gravity helps to ensure that the stars revolve around the center of the galaxy, the earth revolves around the sun and the moon – around the Earth. Why, then, astronauts experience weightlessness, you ask? They are orbiting the Earth. They fall down, but they compensate for this movement. They fall down, but never fall. In orbit altitude of about 402 kilometers above the Earth’s surface gravity is only reduced by 10%.

Myth 7: There is a dark side of the moon

In fact, the dark side of the moon exists only as the album Pink Floyd. The sun shines all sides of the moon at different times. However, there is a side of the moon, which is not visible from Earth. We always see the same side, and the other is “dark” because when we in heaven month (crescent), sunlight illuminates just the other side, we do not see.

Myth 8: The Evolution of a rise from the bottom up

In fact, although natural selection selects a suitable genes from the gene pool, imperfect organisms feel great. Mosses, fungi, sharks and crabs, for example, have remained unchanged for a long enough period of time. Other greatly changed, and not always such that improvements were evident. Evolve to be “in shape” does not mean that there will be progress in the development – just be easier to survive and reproduce in a familiar environment.

Myth 9: In the vacuum of space man explodes

In fact, all the fault of science fiction movies. In the real world this does not happen. People will be able to experience a brief meeting with outer space without a space suit exactly the time at which they will be able to hold your breath. This prevents the lungs from the rupture, which sends air to the blood. However, without oxygen a person falls into a coma and die of suffocation. That’s why it’s so important space suits: they allow to breathe in a vacuum.

Myth 10: Synthetic chemicals are dangerous

In fact, many of the chemicals produced in laboratories and factories are no different from the natural, and very few synthetic products as poisonous as natural substances. In nature there is something that leads to death. Cyanide, for example. Natural substance, the strongest poison. Botulism is also a natural process, but one drink can kill half the people in the city. Poison oak and poison ivy – common plants, but they are extremely dangerous. On the other hand, most of the drugs, prescription prescription created artificially, and their valuable contribution to the life can not be overstated.

Myth 11: The cold causes the common cold

In fact, the common cold is caused by a viral infection of the airways. Viruses do not appear in your body magically just because you forgot a scarf and mittens. For the most part, we greet each other with viruses hand when entering into close contact with other people who are already infected, which means you are putting yourself more at risk of getting sick, staying home with the family coughing, than if you were wandering through the cold forest hatless but one.

Myth 12: 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 1998, an article in the prestigious medical journal The Lancet reported that a common vaccine for children can lead to a PAC. But first, from this article and refused to apologize, and secondly, there was no scientific studies confirming factology article. Despite this, many parents refused to vaccinate their children. Well, Voltaire believed superstition worst enemy of the human race.

Myth 13: Rubber tires protect the vehicle from lightning

In fact, the bus does not save the car from a lightning strike. If you get caught in a storm, while driving, of course, would be safer in the car than outside. Cars provide protection against lightning, but not because of why you think. When lightning strikes the car, it gets to the metal frame, which protects passengers by acting as a conductor and assigning the charge into the ground. It is logical to assume that a convertible or motorcycle does not protect you from a lightning strike, though they tire and rubber.

Myth 14: Kids rage of sugar

In fact, let kids eat their cookies. The researchers found no significant association between the consumption of sugar and hyperactivity. The analysis, published in the Journal of the American Medical Association, found that more than 16 qualified scientists could not identify a significant association between sugar consumption and cognitive performance or behavior. Of course, sugar is mainly affected by obesity (and other problems), and then the parents will still need time to take in children cotton candy.

Myth 15: The Big Bang theory explains how the universe was created

In fact, the theory of the Big Bang merely reflects our observations of the early universe: initially, it has undergone a massive and rapid growth, which continues to this day. Physicist Joao Magueydzho and protects all scientific views on the fact that during the lifetime of the early universe, the speed of light was greater than now (why it is constant and maximal – read here ). The central value of the Big Bang theory is an explanation of the expansion of the universe, and not how it originated. What came before the Big Bang – is another question .

Myth 16: The summer of the Earth closer to the Sun

No, no and no again. For people living on the equator it is true the other way around: the Earth is closer to the Sun in January. But for the people living in the southern hemisphere in January – it’s the best time when you can lie on the beach and drink a cold lemonade. What are the reasons for the change of seasons? The point is tilted axis of the Earth. Earth sways in the rotation. Summer is when the earth receives the most direct sunlight in winter the sun’s rays reach the earth at an oblique angle.

Myth 17: Albert Einstein failed math exam at school

In fact, Albert Einstein was always good at math. Unlike Stephen Hawking . Another version of the myth says that Einstein was basically slow learners. But there is no evidence that this is true: the remaining time sheet genius physicist tell a different story. Of course, lazy kids enjoy this myth: “Even Einstein bad student!”. But unfortunately, “this student was Albert Einstein” – this is not about you, so learn.

Myth 18: People have evolved from chimpanzees

In fact, looking at the chimp, you do not look at his great-grandfather, you’re looking at a distant relative. Humans and chimps evolved from a common ancestor. 95% of human DNA and chimpanzees are the same, but it tells mostly on how much like our body. At some point, our genetic paths diverged, so humans and chimpanzees began to develop according to different genetic codes.

Myth 19: Antibiotics kill viruses

Indeed, antibiotics are brilliant targets poisons that help kill bacteria your body – the bacteria and not viruses. Moreover, the virus can not be killed at all, because he did not live very beginning. When a malicious cough or cold takes hold of us, we all want to take a pill and get rid of them. Unfortunately, so you can not fight against germs that cause colds and flu, and in many cases, antibiotics may make the problem worse. Listen to the doctor, do not self-medicate.

Myth 20: The full moon drives people crazy

In fact, you will kill a full moon in only one case: if you’re a werewolf. Over the centuries, nearly all cultures attributed mystical powers and influence of supernatural creatures in a bright and round face of the full moon. In English, the word «lunacy» (folly) and «lunatic» (crazy) originate from the words «lunar» – associated with the moon, of course. But in spite of the prejudices of men, the science does not show a significant association between the phases of the moon and the acts of murders, aggression, insanity, vandalism or rituals of human sacrifice.

Myth 21: After your death fingernails continue to grow

No, not really. Just think: what would? Tissues of the body to burn energy from food to continue to rise. People do not continue to eat or digest food after death. Furthermore, in case of death the heart stops pumping blood. How are your fingers will get the oxygen needed to sustain life in the tissues and produce new keratin? The same goes for hair.

Myth 22: The coin on the track let the train derailed

Well, try it. Freight trains weigh many tons. With such success, you can say that would upset a tanker petard. Trains, at times, not rolled over and under the threat of a massive: cars or rocks. His legs are growing myth that’s how: once many people have tried to align the coin on the tracks and suffered seriously until death.

Myth 23: Bats – blind

Thank you very much, bats see perfectly. We Chiroderma villosum, for example, have eyes, and those eyes are working perfectly. Where does this myth went? Like dogs, bats rely heavily on other senses, such as hearing and smell. With advanced system of echolocation bats are well oriented in the dark and hunt almost invisible prey. Bats love the night, as opposed to people who for some reason decided that the eyes of nocturnal hunters perform rudimentary function.

Myth 24: The Coriolis effect determines the direction of the discharge hopper

In fact, it is one of the few occasions when Lisa Simpson was mistaken. In one of the episodes of the sixth season of “The Simpsons,” “Bart vs. Australia” Lisa tells his brother about the Coriolis effect, which causes the water to merge counterclockwise in the Northern Hemisphere and clockwise – in the South. However, the Coriolis effect – the name of the inertial force, which determines the trajectory of objects moving in a rotating frame of reference. For example, it determines the rotation of the Earth affects the weather. The amount of water in the toilet too small to be subjected to the Coriolis effect.
