We know a lot of things, we have read dozens of books and watched hours of documentaries. But the world still keeps surprising us. We were amazed by the fact that it takes 12 bees their entire life to make one teaspoon of honey. Now, every morning, we drink tea and thank these hardworking insects.
Selfies kill more people than sharks.
In September 2015, a 66-year-old tourist fell off the stairs while trying to take a selfie near the Taj Mahal and died. This tragic event became the 12th death caused by selfies that year, whereas sharks had killed only 8 people.
There is less time between us and the Tyrannosaurus Rex than there is between the Tyrannosaurus Rex and the Stegosaurus.
The Stegosaurus and its relatives (Allosaurus, Apatosaurus, and others) lived about 155-145 million years ago. And the T-Rex existed around 67 million years ago. So, there is about 83 million years between the Stegosaurus and the T-Rex. And the current era of the geological history of the Earth is Cenozoic, which started 66 million years ago and was marked by the appearance of the homo sapiens.
Today, planes fly slower than they used to in the past.
Today, a direct flight from New York to Houston takes 4 hours. In 1973, the same flight would’ve taken a little less than 3 hours. The thing is, the price for fuel has increased significantly since then. And the air companies understand that they are able to save millions of dollars per year if they just fly slower.
Cleaning at home is just as harmful for your health as smoking a pack of cigarettes.
Inhaling the chemicals contained in home detergents increases the risk of developing asthma by up to 43%. The chemicals irritate the mucus of the breathing pathways and can lead to long-term changes in how they function.
There are so many different kinds of apples, that if you eat one of each kind per day, it would take you 20 years to try them all.
There are more than 7,500 known types of apples in the world. And 20 years is only 7,300 days. So, it would take you more than 20 years to try every single kind.
Wine glasses are 7 times bigger now than they used to be in the past.
At the beginning of the 18th century, a glass of wine could only hold 66 ml of the drink. And today, people often drink from glasses that can fit half a liter. So, in the past 300 years, they have increased in size by 7 times, and the most significant changes have happened in the past 20 years as the consumption of wine has increased.
Steve Jobs chose the name Apple because it was before Atari in the phone book.
There are several legends about how the name Apple was chosen. The most realistic story is when Steve Jobs and Steve Wozniak were driving and Jobs said, “I’ve got a name: Apple Computer.” The guys continued to try to come up with different names, but they couldn’t. Later Jobs said, “And also remember that I worked at Atari, and it got us ahead of Atari in the phonebook.”
关于苹果这个名字是如何被选中的，有一些传说。最现实的故事是史蒂夫·乔布斯（Steve Jobs）和史蒂夫·沃兹尼亚克（Steve Wozniak）开车时，乔布斯说：“我有个名字：Apple Computer。”这些家伙还继续尝试提出不同的名字，但他们想不到其他的了。乔布斯后来说：“还记得我在Atari工作，取Apple这个名字使我们在电话簿中领先于Atari。”
Cows that are called by their names produce 258 more liters of milk per year compared to those that don’t have names.
A study by scientists offers farmers a smart and easy way to make their cows produce more milk: all they have to do is be more attentive to them, pet them, and say their name more often. Researchers think that the cows that have names and are called by them feel more relaxed, whereas stress hormones reduce the production of milk.
One pencil can draw a 56 km line.
A 35-mile line can be drawn with an average pencil (a bit more than 56 km) or it can write 45,000 words.
10. 2,500 years ago, in China, people used knives as money.
Bronze knives played the role of money in the territory of China between 600 and 200 years BC, during the reign of the Zhou dynasty.
Thanks to flat screens and high resolution, dogs can watch TV just like humans.
The picture on a standard TV screen is updated 60 times per second. For the human eye, pictures that appear faster than 50 HZ are seen as continuous motion. And dogs see separate pictures at 75 HZ, because their eyes are designed to react to motion. This is why the video on the screen is probably seen by dogs as separate pictures: the animals most likely see this motion as unrealistic, so they are not interested in it. But modern technology allows us to make high-res screens: this video doesn’t seem to be unrealistic to our pets and seems to hold their interest.
Another reason why dogs don’t watch modern TVs is that the screen is at a level that is comfortable for human eyes. If you put it on the floor, your dog will most likely be interested in what is going on.
Ancient Egyptians bowled 5,000 years ago.
Bowling was popular in Ancient Egypt 5,000 years ago. Egyptians bowled in huge halls, with 2 people playing at the same time (every player was at the end of a 4-meter lane). One person threw a big ball and the other one threw a small one.
Only 5 modern countries have never been colonized by Europe.
Almost every country on the planet was colonized during the period from the beginning of the 16th century until 1960. Some countries were either under protectorate or mandate, and others were completely ruled. And only 5 modern countries were able to avoid European reign completely: South and North Korea, Japan, Thailand, and Liberia.
Rabbits can sense the smell of other rabbits that have been killed in the feces of predators.
European rabbits are prey for 30 different kinds of predators, so it is not surprising that they have developed a lot of different ways to adapt and survive. New studies by scientists have proven that rabbits can sense the smell of their own kind in the feces of ferrets. This gives them a chance to avoid the places where their predators live.
The amount of Nutella sold in the world in a year is enough to cover more than 1,000 soccer fields.
Nutella was first produced in 1940 and children and adults loved it so much that they (and we) still eat a lot of it. And if every single bought bottle of Nutella per year was put on toast, it would be possible to cover more than 1,000 soccer fields with them.
It takes 12 bees their whole entire life to make one teaspoon of honey.
During its entire life (bees live for 4-5 months), an average bee produces only about 1/12 of a teaspoon of honey. So, one teaspoon of the sweet product you put in your tea in the morning took 12 bees’ lives to produce.
Most people can tell the difference between hot and cold water when it is flowing.
96% of people can tell the difference between hot and cold water by ear. A company called Condiment Junkie, that specializes in sound design, came to this conclusion. You can check here to see if you are part of the 96%.
Inside of all of us, there are 0.2 mg of gold.
A 70-kg person contains about 0.2 mg of gold. The volume of gold will be around 10 nanoliters. If you form a cube, every side of it would be 0.22 mm.
Gold is edible.
Food can be incredibly expensive. For example, in New York, you can eat a burger that costs $600 — with lobster, truffles, and... gold leaf.
You can eat a portion of 24-carat pure gold and be healthy. Pure gold goes through the digestive system and doesn’t get absorbed. So, rich people don’t have to be afraid of anything.
Flamingos can drink boiling water.
These birds can drink water that is almost boiling. The thing is, most lakes where flamingos live have a very high concentration of salt. And the only source of potable water for them are boiling geysers.
Being a bad driver is partially a genetic trait.
A small study showed that the inability to drive can be inherited in your genes. 29 people took part in the experiment: 22 without the so-called driving gene and 7 people that had it. The participants with this gene showed results that were 20% worse in the simulation tests, and other tests, than other members of the group.
Fanta was created in Nazi Germany because there were problems with the shipment of the syrup for Coca-Cola.
This drink appeared in Germany in 1940. Because of the embargo that the Allies of World War II imposed, the shipment of the syrup that is necessary for the production of Coca-Cola was stopped. So, a new syrup was created from the products that the country had. It is based on milk whey and apple mash. The drink was very different from what we know now.
