Around 5.5 billion Google searches are done every day. This figure was 2 times lower in 2012. People are learning new things constantly and are trying to make their perspective wider. But even the most ordinary questions can often confuse us: for instance, why is “yellow” called low-quality journalism and how did Professor Dumbledore manage to do magic without his wand?
1. Why do we get “butterflies in our stomach?”
The relation between the stomach’s function and the brain induces this feeling. In the stomach, there are a lot of nerve cells that affect our brain even more than we think. So the brain interacts with the stomach all the time, with all its feelings, ideas, and emotions.
For our bodies, it is considered stressful to be both in love and terrified, because you have the “fight or flight ” response. The levels of cortisol and adrenaline rise, which in turn gives the order to raise blood pressure and increase the flow of blood to the muscles and lungs. The blood flows away from the stomach at the same moment and this causes the sensation of butterflies in the stomach.
2. When we are in the shower, why do we still have brilliant ideas?
Are you troubled by a dilemma all day long and you get the answer in the shower? Here, nothing abnormal. The thing is, your brain slows down for a brief period at times like these and the body feels very enjoyable sensations. The freedom from thought and the warmth offered by the shower makes your brain more imaginative.
Showers promote the development of dopamine in your blood, just like workouts and pleasant music. You relax, you transfer your mind to something else, and you don’t push your brain to function. Your conscience is grateful to you and it gives you a creative response.
3. Why are tears salty?
Nearly 99% of tears are water and the remainder, including salt, are non-organic compounds. The amount of salt in your tears depends on your body’s condition and the reason why you weep.
When they sob because they feel sad, people have the saltiest tears. When a person weeps, their thyroid functions more and their heart rate rises. The tension that is similar to physical activity is perceived by the body. This is the reason why our sweat is salty as well.
And when we’re smiling and weeping, the tears aren’t that salty at all. When viewed under a microscope, they also look different.
4. Why is autocorrection called T9?
Not to correct our spelling, but to help us write, T9 was made. The argument was the word a user wanted to enter to guess. If you remember the old phones, you know that on each button there were 3 or 4 letters. Once, we had to click the buttons and the machine attempted to guess what word we wanted to type.
So, it’s very easy to name the system: Text on 9 keys.
5. Why do magicians need a wand to perform magic?
Professor Ronald Hutton of the University of Bristol says a wand is a handy tool for a wizard to concentrate their power on the appropriate object and guide it to it.
But without their wands, great wizards in the world of Harry Potter (such as Albus Dumbledore) could often do magic. This suggests that their strength could be managed so well that they didn’t need an extra method.
6. “Why is” yellow “labelled low-quality journalism?
The whole world calls journalism of poor quality “black” journalism. Usually, it is about tabloids that report on controversies and other unsavoury material. In 1895, in The World, the American artist Richard Outcault published a collection of frivolous drawings. There was a picture of a child wearing a yellow shirt among them that said some funny stuff.
The photos were beloved by American readers and the boy was dubbed “The Yellow Kid.” Shortly after that, the New York Journal began publishing identical photographs and the newspapers had a fight over which of them was entitled to use “The Yellow Kid.”
In 1986, Erwin Wardman, the main editor of the New York Press, called the “black press” of both newspapers, attempting to suggest that they were both willing to use whatever means necessary to achieve their goals. This word was coined by him and it soon became famous.
7. Why do old photographs show people holding each other’s hands on their shoulders?
How difficult is it for a picture to be taken? Well, this process took longer than several seconds when photography only emerged. It took several minutes to an hour, unlike today. And during this period, people had to keep still to ensure the picture would look fine. So, for individuals, most photo shops offered various choices, including sculptures that you could rely on for the time needed.
But if you had a few people in the frame, it would be easier to place your hand on someone else’s back. Holding the balance this way and remaining motionless is easier.
8. Why are iPhone images displaying a time of 9:41?
Steve Jobs was on the stage of the Macworld Conference & Expo on Tuesday, January 9, 2007, talking about the emerging technologies of the future. He said he had looked forward to that day. And he launched the iPhone at 9:41. So, the time we see on the devices’ displays in all the Apple commercials is the exact time that the first iPhone was released.
9. In American movies, why are there no toilet brushes?
It can be difficult to find toilet brushes in US toilets. The thing is that in the US, the drain system is much more efficient. So, whatever gets into the toilet gets flushed down the drain with the stream.
In Europe, the pipes are almost at the same level as the shower, so there is no extra pressure and the flush is not always as effective as it needs to be. The strain is high enough in the United States that they don’t need toilet brushes.
