10 scientific facts that will be interesting even for the skeptics

    The world around us is really versatile and extremely diverse. That is why people are often skeptical to everything magical and mystical that they see around them. We have compiled a list of the most unusual facts and interesting stories that will make even the most inveterate skeptics to think that the world is actually not only a science, but also the magic!

       1. Every time you smell violets, you smell it for the first time.

    Try to remember what flavors have violets? A very vague memories, is not it? No wonder. The smell of violets is formed by the substance called ionone, which is very specifically interacts with our olfactory receptors.

    After stimulation of receptors by ionone, it connects with them and turns them off. You can no longer smell violets, no matter how much you do not sniffed. After a couple of breaths buds begin to work as usual, but your brain recognizes the scent of violets as a completely new impetus. Therefore, every time when you smell violets you feel it for the first time.

       2. Saturn's density is so low that it could float in water.

    The gas giant Saturn is the second largest planet of the solar system after Jupiter. Their diameter varies by only 19%, but Saturn weighs three times less than its massive neighbor. Saturn is the only planet in the solar system, the average density of which is less than the density of water.

       3. In nature, there are underwater waterfalls.

    "Um, what?" - Might say the skeptics. In fact, it is not surprising, if you remember high school physics. Cold water is heavier than warm water, as it has a higher density. So when in the ocean there are two flows - the colder and warmer, one of them literally falls to the bottom. Water with Different salinity plays its role.

    One of the most famous underwater waterfalls is located in the Denmark Strait, which separates Greenland and Iceland. Its height is 4 kilometers, but unfortunately you cannot see it with your own eyes.

       4. The color of the Universe is called the "cosmic latte."

   

Once the researchers took data on light emission of more than 200,000 galaxies, they saw which color could be if the colors will occupy a whole sky. It turned out that the average color of the light in the universe - it is beige, reminiscent of a latte. So he eventually called cosmic latte.

    If you want to use "cosmic latte" in the graphical editor, here it’s RGB-record: # FFF8E7.

       5. The body of the person can turn himself into soap.

    If protect human corpse from the effects of bacteria and insects, for a long time it can remain relatively intact through the process, which is called "saponification" - the transformation of cells of adipose tissue into the stearin compounds, to put it simply - in the soap.

       6. In some circumstances, hot water can freeze faster than cold.

    This phenomenon is known for the skeptics in science as the Mpemba effect, which is mentioned in writings of Aristotle, Francis Bacon and René Descartes, but its scientific name appeared only in 1963, when it had been re-opened.

    The essence of the effect is that if you put in the freezer two cups with hot and cold water, hot water freezes faster in some circumstances. From the point of view of physics at the phenomenon can have a lot of different explanations, but which of them is most true - scientists are still not decided.

       7. Sun on Mercury can get up and sit down at one point.

    Mercury revolves around the sun in eccentric orbit - this means that the star is strongly shifted relative to the center of rotation of the planet. In addition, Mercury is very slowly rotates around its axis. All this leads to the fact that the Sun on Mercury's sky can change direction and get up and sit down in the same point of the horizon at a mercurial day.

       8. In a group of 23 people there is more than 50% probability that two people will have the birthday at one day.

    Looks like something impossible for skeptics, however, need to take into account that if you are considering a group of 23 people, you need to take into account any possible pairs of birthdays, which in general is typed 253. Out of this, the more likely turns out that someone will have birthday in one day than that everyone will have a personal birthday. Skeptics probably will try to make some researching.

    This fun fact called birthday paradox, though strictly speaking it is not a paradox - it is simply a consequence of the theory of probability, which is not consistent with the usual intuitive representation. It is also interesting that if you take a group of 60 people, the probability of coincidence of two birthdays will be more than 99%.

       9. Standing on the equator, you are moving at a speed of about 1,600 kilometers per hour.

    Linear speed of the Earth's rotation around its axis at the equator is 465.1013 m / s or 1674.365 km / h - it is so fast you will be moving with respect to the planet's center, standing on the equator.

       10. On Jupiter's moon Io there are no seas and oceans, but there are tides.

    These tides consist of hard stones. Yes, the gravitational influence of Jupiter and its other moons so great that makes Io's surface to rise and fall at a height of 100 meters. To better imagine this hell - that's about the height of a 30-storey building. These tides cause very high volcanic activity on Io.
