There are around 5.5 billion Google searches done per day. In 2012, this number was 2 times lower. People are constantly learning new things and are working on making their outlook broader. But sometimes, even the most ordinary questions can confuse us: for example, why is low-quality journalism called “yellow” and how did Professor Dumbledore manage to do magic without his wand?
We at Apegeo decided to find answers to questions like this. As it turns out, even the strangest things can be explained.
1. Why do we get “butterflies in our stomach?”
This sensation is caused by the connection between the work of the stomach and the brain. There are a lot of nerve cells in the stomach that influence our brain a lot more than we think. So the brain, with all its feelings, thoughts, and emotions, communicates with the stomach all the time.
For our bodies, both being in love and being scared is considered to be stressful, so you have the reaction “fight or flight.” The cortisol and adrenaline levels rise which in turn gives the command to make the blood pressure higher and increase the blood flow to the muscles and the lungs. At the same moment, the blood flows away from the stomach and this causes the sensation of butterflies in the stomach.
2. Why do we sometimes have genius ideas when we are in the shower?
You have been bothered by a problem for the entire day and you get the solution in the shower? Nothing abnormal here. The thing is, at moments like these, your brain shuts down for a short time and the body experiences very pleasant sensations. The freedom from thinking and the comfort the shower provides makes your brain more creative.
Showers, just like workouts and nice music, stimulate the production of dopamine in your blood. You relax, you switch your attention to something else, and you don’t force your brain to work. Your consciousness is grateful and it gives you a creative answer.
3. Why are tears salty?
Almost 99% of tears are water and the rest are non-organic compounds including salt. The amount of salt in your tears depends on the state of the body and the reason why you are crying.
People have the saltiest tears when they are crying because they feel miserable. When a person is crying, their thyroid works more and their heart rate increases. The body experiences tension that is similar to physical activity. This is why our sweat is also salty.
And when we are happy and we are crying, the tears are not that salty at all. They even look differentwhen seen under a microscope.
4. Why is autocorrection called T9?
T9 was created not in order to correct our spelling, but to help us type. The point was to guess the word a user wanted to enter. If you remember the old phones, you know that there were 3 or 4 letters on each button. We had to press the buttons once and the system tried to guess what word we wanted to type.
So, the name of the system is quite simple: Text on 9 keys.
5. Why do wizards need a wand to do magic?
Professor Ronald Hutton from the University of Bristol says that a wand is a convenient tool for a wizard to focus their power on and direct it to the necessary object.
But great wizards in the world of Harry Potter (such as Albus Dumbledore) could sometimes do magic without their wands. This means that they could control their power so well that they didn’t need an additional tool.
6. Why is low-quality journalism called “yellow?”
The entire world calls low-quality journalism “yellow” journalism. It’s usually about tabloids that focus on scandals and other unsavory things. In 1895, American artist Richard Outcault posted a series of frivolous pictures in The World. Among them, there was a picture of a child wearing a yellow shirt that said some funny things.
American readers loved the pictures and the boy was called “The Yellow Kid.” Soon after that, the New York Journal started posting similar pictures and the newspapers had a dispute over which of them had the right to use “The Yellow Kid.”
In 1986, the main editor of the New York Press, Erwin Wardman, called both newspapers “yellow press” trying to say that both of them were ready to use any means necessary to achieve their goals. He coined this term and it soon became popular.
7. Why do old photos show people with hands on each other’s shoulders?
How hard is it to take a photo? Well, when photography just appeared, this process took longer than several seconds. Unlike today, it took from several minutes to an hour. And people had to stay still during this time to make sure the photo would look good. So, most photo shops offered different options for people, even sculptures you could lean on for the required time.
But if there were several people on the photo, it was easier to put your hand on someone else’s shoulder. It is easier to keep your balance this way and stay motionless.
8. Why do iPhone pictures show the time 9:41?
On Tuesday, January 9, 2007, Steve Jobs was on the stage of the Macworld Conference & Expo talking about the new technologies of the future. He said that he had been looking forward to that day. And at 9:41, he presented the iPhone. So, the time that we see in all the Apple advertisements on the screens of the devices is the exact time when the first iPhone was announced.
9. Why are there no toilet brushes in American movies?
In US toilets, it may be hard to find the toilet brushes. The thing is, the drain system is way more powerful in the US. So, whatever gets into the toilet gets flushed with the water down the drain.
In Europe, the pipes are on almost the same level with the toilet, so there is no additional pressure and the flush is not always as effective as it needs to be. In the US, the pressure is high enough that they don’t need toilet brushes.
Bonus: A pregnant woman can get… pregnant.
Julia Grovenburg is considered to be the 11th woman in history to have given birth to children of different ages. They were born on the same day but their daughter is one month older than their son. Doctors call this amazing phenomenon superfetation.
This can happen if there are not one but 2 eggs in the female body. The first is fertilized during sex, and the second is fertilized a little bit later.
Usually, hormone changes exclude the possibility of a second fertilization but there are rare exceptions. Doctors estimate the chances of getting pregnant this way as 1 : 1,000,000.
