The number of scientists worldwide is approximately eight million. If each of them worked on a project for ten years, they would make hundreds of new discoveries.
The theories we know are constantly being proven, disproved, or corrected in all areas of science, while a lot of other interesting things are waiting to be discovered.
In this article we present you some interesting things that overturn several popular theories and that will probably surprise you.
The most dangerous country in the world is the Vatican
Here’s a fact that deserves to be on any list of interesting things. This surprising paradox was born out of the way statistics are made.
The number of crimes that occur in a year should be related to the population of the place. The population of the Vatican is much smaller than that of Sao Paulo or Lagos.
For example, in 2006, the population of the Vatican numbered 492 inhabitants, while 827 crimes were registered on its territory. As a result, the statistical crime rate turned out to be the highest in the world – 1.68 cases for every citizen.
Sloths can hold their breath for 40 minutes underwater
Sloths are animals known for their quiet lifestyle. From time to time, they are forced to swim.
A sloth moves two meters per minute on land and five times faster in water! Due to their low metabolic rate, they can stay without air for a very long time. The human tongue has no special areas to detect different tastes
We’ve all heard that you can taste sweet with the tip of your tongue and that bitter taste buds are at the base of your tongue. However, it seems that the taste map of the tongue is just a myth.
Different taste buds are actually spread over the entire surface of the tongue. The illusion of the existence of certain areas is due to the prevalence of certain similar papillae in certain areas of the tongue.
Dogs can distinguish the colors blue and yellow
Even though they can “smell” bad people, dogs don’t see the world in black and white. The old myth about the world seen in two colors has been demolished by Russian scientists.
The experiment was based on the recognition of full and empty food bowls, which had different colors. The experiment showed that the quadrupeds can recognize the colors blue and yellow as well as humans, but they cannot see the difference between green and red. Officially, there are at least three Santa Clauses in the world
These are cities in the USA, located in the states of Georgia, Arizona, and Indiana. In Indiana, maps with special places for celebrating Christmas have been sold for many years.
Here, tourists can meet Santa Claus, who is the main symbol of the holiday.
“Santa Claus” in Georgia is a small town that can only boast of a park, a church and eight streets with names related to the Christmas holiday, such as “Rudolf Street” or “December Street”.
The third town called “Santa Claus”, in the state of Arizona, is a ghost town, consisting of only a few buildings located along a road.
The sheep fight among themselves after being sheared, because they no longer recognize each other
Each flock has its own hierarchy and the rank depends on the gender and age of a sheep. Leaders get better seats when feeding or resting and can control the behavior of the other sheep.
Things don’t change until the sheep are sheared, leading to a mini-revolution. In addition to their characteristic features, appearance and smell, the sheep also lose their status and must fight to find out who is worthy to be the leader.
No apples fell on Newton’s head
Isaac Newton simply witnessed a fruit fall, which led to the formulation of the law of universal gravitation. The fall of the apple made the English physicist think about why all apples have the same trajectory.
William Stuckeley, the scientist’s biographer, mentioned this in the book “Memoirs of the Life of Isaac Newton”. Thanks to this book, the legend was born that the apple had fallen on Newton’s head. Changing the background on your screen can reduce stress levels
If stress has cornered you, you need to change your surroundings. This rule also applies to the background on your computer screen.
A new image can lower your stress levels and boost your productivity. Nature pictures are considered the most effective, while cityscapes and geometric figures are the least effective.
Gorillas can purr like cats
In addition to our pets, the following animals can also purr: gorillas, lemurs, guinea pigs, bears, foxes, hyenas, rabbits and squirrels.
Gorillas can even purr while feeding. Moreover, in 2016 it was found that gorillas“sing”when they eat.
In total darkness, the human eye can spot a lit candle from 43 kilometers away
We are not able to fully realize the strength of our vision because the horizon line limits us even on flat ground. At a distance greater than 4.8 kilometers, our view is influenced by the shape of the Earth.
Only man can, in fact, see at amuch greater distance. If the Earth were flat and there was total darkness, we could see a flame from 43 kilometers away.
A ton of mobile phones contains more gold than a ton of gold ore
According to ecologists, processing a ton of ore results in 1-2 grams of gold. You can get the same amount of precious metal if you process all gold-containing pieces from 41 mobile phones.
One ton of such devices contains almost 300 grams of gold. But the price of the phones is too high for the process of obtaining gold from them to be profitable.
Of course, there are many other interesting things that can turn our ideas about the world upside down. If you know such curiosities, please tell them in the comments section below.
