How do cats purr? What was the actual speed of the tyrannosaurus? What was Caligula’s real name? A lot of interesting facts are omitted during classes, but it’s never too late to expand your knowledge.
Craftside has found the answers to the most perplexing questions and we are ready to share that information with you.
Most Interesting Facts About Our World
1. Cats Are Right And Left-handed
Scientists at Queen’s University, Belfast, have conducted research that has shown that, in most cases, cats use the same paw to play or eat. Unlike people, the number of right-handed and left-handed cats is almost the same, although most females are right-handed.
2. 500 Years Ago, Watermelons Looked Different
If we look at Giovanni Stanchi’s 17th-century painting, we can hardly recognize the watermelon. This fruit came to Europe from Africa and looked completely different 500 years ago. Today’s watermelons look the way they do because of the selection processes and their level of lycopene (the substance that makes them red).
3. You Are More Likely To Meet A Spider If You Are Afraid Of Them
If you don’t like these creatures, you are more likely to find the one in your bed. This is because our attention is called in order of priority, where the most important things are done first. If you are afraid of spiders, this automatically places the spider at the top of your priorities, meaning that if there is one in the room, you will be the first to find it.
4. The Sun Is White
Although the sun is known as a yellow dwarf star, its color is quite different. In fact, the sun is really white, but it looks yellow because we see it through the filter of our blue atmosphere.
This thick layer of atmosphere at sunrise and sunset makes the sun appear more orange or red. And when we look at it through the thinnest layer of air at noon, the sun looks almost white, but it still has a yellow hue.
5. Cashew Nuts Grow In “Apples”
These nuts grow on a “cashew apple“, which is just a yellow or red stem 2 to 4 inches long. In botanical terms, the cashew nut is an accessory fruit that grows on the cashew seed which we call the nut.
6. Cats Purr With The Help Of Their Vocal Cords
The most recent studies show that the “purring mechanism” is a small group of thin bones. It is located between the base of the skull and the root of the tongue. During pleasant moments, the muscles contract and cause the vocal cords to vibrate.
7. Pure Sapphires Are More Expensive Than Diamonds
The myth about the high value of a diamond only appeared recently in the 20th century, thanks to De Beers’ marketing experts. The motto “A diamond is forever” was introduced in 1947, and Marilyn Monroe became its face.
The high price of diamonds is related to absolutely nothing. But sapphires were prized even in ancient Persia, they are still very rare and precious stones, and their price can be much higher than the price of a diamond.
8. 10% Of A Cat’s Bones Are In Its Tail
There are approximately 240 bones in a cat’s body, and 23 of them are in the tail (that means 10%). Cats with short tails are the exception to this rule.
9. Modern Bug Repellents Don’t Frighten Off Insects, They Hide The Human Being
The chemicals in repellents influence the mosquito’s odor, which means they block receptors that help insects find their victims. Thus, with the repellent, a human being technically becomes “invisible” to mosquitoes.
10. Unlike Other Planets, Venus And Uranus Rotate Counterclockwise
All the planets in our Solar System rotate clockwise, except Venus and Uranus. This phenomenon is called retrograde rotation. Venus rotates from east to west and Uranus’ axis of rotation is more inclined relative to the pole of its orbit, turning almost “sideways”.
11. Aviator Sunglasses Are Designed For Military Personnel
The name of these sunglasses is quite logical. They were created in 1938 for American pilots and were available exclusively to them. The popularity of the glasses took off after World War II when ordinary Americans attempted to copy the war veterans who returned home.
12. Clouds Can Move At Speeds Above 95 Km/h
People may think that clouds travel very slowly, but in fact, they can move faster than cars. The high cirrus clouds are 8.5 kilometers above Earth and their speed depends on the speed of the wind in this layer of the atmosphere. These clouds can reach speeds of up to 250 km / h. This is equal to the speed of a train.
13. People Cannot Sneeze While Sleeping
Sneezing occurs due to irritation of the nasal cavity. When we sleep, our sensitivity is much lower and the impulses are not as strong. But if there is a strong incentive (like smoke, for example), the human body will wake up. In fact, if the irritation is very strong, a human being can sneeze and wake up simultaneously.
14. In Australia, The Number Of People Who Die From Bee Stings Equals The Number Of People Who Die From The Snake And Spider Bites
Although Australia is famous for spiders and poisonous snakes, its bees and wasps are also extremely dangerous. According to national studies, mortality rates are almost the same. Its bee and wasp venom can cause a severe allergic reaction, and many people underestimate the danger and don’t see a doctor as soon as possible.
15. Tyrannosaurus Rex Couldn’t Run
Scientists at the University of Manchester built a computer model and showed that this dinosaur could not run, but walked fast. Its weight exceeded 7 tons and research confirmed that running was bad for the skeleton.
In summary, the top speed of the tyrannosaurus was only 16 mph. As a result of this research, paleontologists are now discussing their eating behavior, because there is a new assumption that tyrannosaurus may have been a scavenger.
16. Caligula’s Real Name Was Caius Caesar
The future emperor was nicknamed Caligula (meaning “little soldier’s boot”) in his childhood because he used to wear the Legionnaire’s uniform. The real name of the man who is well-known as an insane tyrant is Gaius Julius Caesar Augustus Germanicus. But it was Caligula that the descendants remembered best.
