As we get older, we lose our childhood curiosity. From the height of our experience it seems to us that we know everything, but there is absolutely nothing that can surprise us. Or not? We invite you to see if you can easily answer children’s questions that confuse most adults.
Zebra – black or white?
There are many theories as to why zebras have such unusual colors. Some scientists believe that this pattern protects against insect bites. Experience has shown that horses covered with striped rugs are less likely to be attacked by African horseflies. Other scientists believe that black and white stripes are necessary for thermoregulation: keeping warm in cool weather and reflecting rays in hot weather. But the most surprising thing is that the zebra under the multi-colored fur is actually black.
Meanwhile, dingoes and the marsupial wolf, thought to be extinct due to overhunting, also had similar stripes. We have talked about extinct animal species before.
Why doesn’t the spider stick to the web?
Spiders can avoid sticky areas thanks to the special claws on their legs and their position. However, the spider always moves only along smooth radial (centre) threads and never along sticky, concentric (circular) threads.
Why is the sky blue but clouds do not fall to the ground?
Each color has a wave emission spectrum. Our eyes see the sky as blue due to the scattering in the atmosphere of short wavelength colors such as blue and violet and, less frequently, long wavelength colors orange and red. In this case, clouds do not “fall” to the ground in the form of ice and water crystals. The size of each drop is 1 micrometer. Due to upward currents from the ground, clouds are held in the sky until they become too heavy.
Where does lightning come from?
Even if your physics teacher seems to know the answer to this question, it’s just a trick. In fact, not much is known about the nature of lightning, especially ball lightning. Yes, we know that hot steam rises and forms clouds where positive and negative charges accumulate. For example, did you know that approximately 50 lightning strikes the earth’s surface every second? We have even learned to create small lightning strikes in artificial conditions, but there is a nuance that contradicts our knowledge of electricity. The truth is that the electric field in a thunderstorm is about ten times less than that required to create lightning, so we don’t actually know how such a powerful discharge is produced.
Why do cucumbers have bitter “butts”?
Due to lack of water or other adverse conditions, a toxic organic compound called cucurbitacin appears in cucumbers, which makes the fruit taste bitter.
Why do mosquitoes drink blood?
The blood of humans and animals contains a protein that mosquitoes need to produce offspring. Therefore, blood drinkers are female mosquitoes, but they do not drink for food.
Why was the main character’s name Baby in the cartoon “Carlson Who Lives on the Roof”?
If Eduard Uspensky explained the extravagant nickname Uncle Fyodor in the cartoon “Three from Prostokvashino” by the wisdom of his little hero, an incorrect translation intervened in the works of Astrid Lindgren. In the original story, the character was revealed to have the Swedish name Svante Svaneson, nicknamed Lillebror – “little brother”. He also had a sister, Bethan, and a brother, Bosse. His childhood was in Soviet cartoons and book translations.
Why can’t you divide by zero?
Everyone remembers from school that it is possible to multiply by zero, but not to divide. But why? From a mathematical perspective, you will need to find a number that when multiplied by zero will give a number. However, we know that when any number is multiplied by zero, the result is zero. The problem has no solution, so the result will be an infinite or indefinite number. Let’s take the equation 0 · x = 0. Let’s try to take x = 4. We get 0 · 4 = 0. Is it true? So 0 : 0 = 4? But this way you can take any number and add 0:0 = 12, 0:0 = 417 etc. you can get it.
Why do wolves howl at the moon?
Wolves don’t actually howl at the moon. For them, howling is just a way to communicate over long distances. This is how they inform their relatives about their location, threats from other predators or prey. That’s why they howl not only at night but also during the day. Apparently, the legend of the mystical connection between the wolf and the Moon arose among our ancestors, who in ancient times entertained themselves by writing stories. Otherwise we would not know the legends about werewolves.
Do polar bears hibernate?
Surprisingly no. They sleep as usual, and only pregnant or lactating female polar bears hibernate. At the same time, brown and polar bears are the closest relatives. Their common ancestor lived only 150 thousand years ago; This is a very short period of time by evolutionary standards. In the wild, both species interbreed. At the same time, during the mating season, polar bears begin to actively feed, so their weight increases to over 200 kilograms. This allows them to sit in the den and feed the newborn pups.
