Newborns usually have about 270 bones, most of which are very small. This makes the skeleton more flexible and helps the baby pass through the birth canal and grow quickly. Many of these bones grow together as they grow older. An adult skeleton has an average of 200-213 bones.
2. The Eiffel Tower grows 15 centimeters in summer
The huge structure is built with temperature compensators, thanks to which the steel can expand and contract without any damage.
When the steel heats up, it begins to expand and takes up more volume. This is called thermal expansion. Conversely, a drop in temperature leads to a decrease in volume. For this reason, large structures such as bridges are built with expansion joints that allow them to change in size without damage.
3.20% oxygen is generated in the Amazon rainforest
Flickr.com/thiagomarraThe Amazon rainforest covers 5.5 million square kilometers. The Amazonian jungle produces a significant portion of the oxygen on Earth by absorbing great amount carbon dioxide therefore they are often called the lungs of the planet.
4. Some metals are so reactive that they explode even on contact with water
Some metals and compounds - potassium, sodium, lithium, rubidium and cesium - exhibit increased chemical activity, so they can catch fire with lightning speed upon contact with air, and if they are immersed in water, even explode.
5. A teaspoon of a neutron star will weigh 6 billion tons
Neutron stars are the remnants of massive stars, consisting mainly of a neutron core covered with a relatively thin (about 1 km) crust of matter in the form of heavy atomic nuclei and electrons. The nuclei of stars that died during a supernova explosion were compressed under the influence of gravity. This is how superdense neutron stars were formed. Astronomers have found that the mass neutron stars can be comparable with the mass of the Sun, despite the fact that their radius does not exceed 10–20 kilometers.
6. Every year Hawaii approaches Alaska by 7.5 cm
The earth's crust consists of several huge parts - tectonic plates. These plates are constantly moving with the top layer of the mantle. Hawaii is located in the middle Pacific plate, which slowly drifts northwestward towards the North American Plate, on which Alaska is located. Tectonic plates move at the same speed as human nails grow.
7. In 2.3 billion years, Earth will be too hot for life to be possible.
Our planet will eventually become an endless desert, similar to today's Mars. For hundreds of millions of years, the Sun has been heating up, getting brighter and hotter and will continue to do so. In more than two billion years from now, temperatures will be so high that the oceans that make the Earth habitable will evaporate. The entire planet will turn into an endless desert. As scientists predict, in the next several billion years, the Sun will turn into a red giant and completely swallow the Earth - the planet will definitely come to an end.

9. Light will take 8 minutes 19 seconds to get from the Sun to the Earth
It is known that the speed of light is 300,000 kilometers per second. But even at such a dizzying speed, it will take time to cover the distance between the Sun and the Earth. And 8 minutes is not so much on a cosmic scale. To reach Pluto sunlight it will take 5.5 hours.
10. If you remove all interatomic space, humanity will fit in a sugar cube
In fact, more than 99.9999% of an atom is empty space... An atom consists of a tiny, dense nucleus surrounded by a cloud of electrons, which proportionally take up more space. This is because electrons move in waves. They can only exist where the crests and troughs of waves add up. in a certain way... The electrons do not stay at one point, their location can be anywhere within the orbit. And therefore they take up a lot of space.
11. Stomach juice can dissolve razor blades
The stomach digests food thanks to caustic hydrochloric acid with a high pH (hydrogen index) - from two to three. But at the same time, acid also affects the gastric mucosa, which, however, is able to quickly recover. Your stomach lining is completely renewed every four days.
Scientists have many versions of why this is happening. Most likely: due to huge asteroids that influenced its course in the past, or because of the strong circulation of air currents in the upper atmosphere.
13. A flea can accelerate faster than a space shuttle
Jumping fleas reach mind-boggling heights - 8 centimeters per millisecond. Each jump gives the flea an acceleration of 50 times the acceleration of the spacecraft.
And what Interesting Facts do you know?
We've tracked down scientific articles proving the benefits of owning pets and are sharing our findings with you. For example, cats reduce, not increase (as many thought) the risk of allergies in children.
Prevention of allergies in children
It used to be thought that having a cat or dog in your home increased your child's risk of allergies. And if there is a hereditary predisposition, then the doctors recommended not to have pets. However, this view is not just outdated, now science has turned it 180 degrees.
There is a growing body of research proving that children growing up with pets (and it doesn't matter with a cat or dog) are less likely to develop allergies and asthma.
Pediatrician, scientist James E. Gern, MD, of the University of Wisconsin-Madison conducted a study, checking the blood of children: immediately after birth and after a year. Children who grew up with a pet dog suffered much less from allergies - 19% versus 33% - among those who grew up without pets. They also had lower levels of eczema overall. In addition, children growing up with pets had higher levels of certain components of the immune system.
Reducing the risk of dying from heart disease
Several scientific research showed that heart attack survivors with pets live longer than those in the same situation but without pets.
Male pet owners are also generally less likely to suffer from heart disease.
In addition, there is research proving that the risk sudden death heart attack rates for pet owners are much lower. Researchers at the University of Minnesota have calculated that cat owners have a 30-40% lower chance of dying from a heart attack than those without pets.
Lower blood pressure
Doctor Karen Allen conducted a study among 48 randomly selected brokers (working in a constant stressful situation). The study compared 24 pet owners and 24 people without pets and found that pets improved blood pressure and stress hormone levels better than medications (ACE inhibitors).
Reducing cholesterol levels
Back in the early 90s, research data was disseminated American Health Association states that cat owners generally have lower blood cholesterol and triglyceride levels. What's more, the study says having a pet lowers these levels.
Too much high level triglycerides can potentially contribute to the development of atherosclerosis and myocardial infarction.
Reduced stress
In one study, researchers showed that people who received a stressful task showed less stress when their pets were with them. This level was even lower than in the presence of a spouse or acquaintance. Apparently, because pets love the owner unconditionally and do not appreciate his actions.
In general, there are several studies conducted to prove that pets play the role of a natural "medicine", providing a sedative effect in the inevitable stressful situations... For example, one of them studied how long it takes to recover normal performance pressure and pulse rate of a person after stress. It showed that dog and cat owners experience less psychological and physical stress and are able to recover faster. Therefore, it is not at all surprising that some people take their beloved pets with them everywhere.
General health promotion
In the early 90s of the last century, a group of researchers from the University of Cambridge found that those who acquire a pet improved overall health in just a month. These positive changes continued throughout the 10 months of the study. It has been observed that pet owners are less likely to suffer from colds or headaches. It was later found that male owners of cats or dogs have a more even heart rate and stable blood pressure than those who have not yet acquired a pet.
There are also scientific observations showing a generally longer life span for pet owners.
Already read: 6326 timesFriends, today we would like to lead 30 irrefutable and scientifically proven facts about our body and food that we eat every day. Read on to find out where we got white bloom on our tongue and at what hours our liver processes alcohol best!
So here are the bodily food facts and about what is associated with our digestion and food intake:
Your hair can support the weight of a whole apple. Scientists have not yet specified the size of the apple.
You have as many bacteria in your mouth as there are people on our planet.
The lining of your stomach is renewed every 3 days.
There is so much acid in our digestive system that with its help you can easily digest an iron nail. But we do not advise you to experiment, just take our word for it!
Your body produces approximately 1 liter of saliva every day.
Some scientists believe that the saliva that you have produced during your life can fill two pools. And the saliva of these scientists, of course, too!
White bloom in the language that you see every morning - these are cells that died during the night.
The liver breaks down alcohol most actively between 18:00 and 20:00. So plan your active get-togethers with these hours in mind!
Men have much fewer taste buds on their tongues than women. Therefore, we pour all dishes with ketchup and mayonnaise. And do not be offended by this!
1/2 of your (sorry) bio-waste is bacteria.
Your tongue print is absolutely unique, keep this in mind when showing it bad people. :)
By the way, it is the tongue that is the strongest muscle in our body. Not what you just thought. :)
A person's ability to eat inedible objects, such as swords, spoons, stones, plastic, etc., is called polyphagia... Small objects leave the body along with feces, and large ones remain until they begin to bother the owner. We do not recommend eating anything inedible - it is better to try the dishes according to our recipes, which can be prepared for a festive table or quickly and tasty!
The sword swallowers actually swallow these most inedible swords - this is proved by X-rays. The length of the sword can reach as much as 62 cm! I wonder how they get them then ?!
For 24 hours every day, you excrete about 1 liter of bile.
Our intestines are about 9 meters long. This is what you need to measure, and not what is usually measured!
Your stomach can hold about 4 liters of partially digested food.
Are you addicted to fasting? It's a good thing, but do not starve for more than 1 day - otherwise you will provide yourself with permanent headaches, weakness and lethargy. In addition, fasting is bad for diabetics and heart patients. Use the section of our website with recipes for lean dishes and diet dishes.
How much does a person's heart weigh? The heart of every adult weighs approximately 220-260g.
The most common food allergy in the world is cow's milk allergy. For those who do not have it - use our recipes to quickly and easily prepare the most delicious milk recipes according to our recipes!
Our navel is scientifically called umbilicus... Great nickname for a dog - use it to your health!
99% of all calcium in our body is found in our teeth.
In terms of hardness, the enamel of your teeth can be compared to quartz.
During the day, your body can generate as much heat as is enough to bring 30 liters of cold water to a boil. How do you fight the annual blackout hot water?
Bumping your head against a wall loses about 150 calories per hour. Here it is - the most reliable way to lose weight!
The fat in our body is enough for an average of 7 pieces of laundry soap. Plus we can also heat water! Just a bath and laundry complex of some kind.
Overweight women give birth to smart children - scientists have found. Remember this when dealing with the opposite sex!
The stomach uses hydrochloric acid (HCl) to digest food. Yes, yes, the one that melts our skin and causes burns in films!
Your body contains as much chlorine (Cl) as is enough to disinfect as many as 5 pools (2 of which, most likely, are filled with your own saliva). :)
