10 Interesting Facts for "Curious Minds" Who Want to Know Everything
1. Why don't we remember our childhood and how we were born?
This happens due to the inability to associate events with words since we couldn't speak yet and didn't know the words to describe any event. The connection between consciousness and language is much stronger than we think.
2. Why do men have nipples?
Nipples form during the intrauterine stage. Between 10 and 15 weeks of fetal development, male and female embryos are exactly the same. Afterward, a surge of hormones occurs, initiating the formation of sexual characteristics. Nipples appear in the embryos of both sexes before this hormonal surge. Thus, the presence of nipples in men is explained by the biological processes of embryonic development.
3. Why do people often not recognize their own voice in a recording?
Because sound is transmitted differently in different environments, when we speak, the inner ear "catches" not only the vibrations coming from the outside through the auditory canal but also those coming directly from the vocal cords through the head. Therefore, the sound of our voice is distorted for ourselves by default.
4. Why do average students often succeed more than top students?
Average students tend to worry much less about their failures. Moreover, they have to revise their work several times and withstand criticism from teachers and parents. Top students are prone to perfectionism. They are used to being praised, paid attention to, set as an example, etc. When adult life begins, it turns out that they lack self-confidence in situations where everyone disregards you.
5. Why does nettle sting?
Upon contact with the skin, nettle causes such a strong feeling of discomfort because this plant secretes a mixture of three poisonous chemicals when the delicate hairs on its leaves come into contact with our skin.
6. Why does the déjà vu effect occur?
The déjà vu effect is caused by the previous unconscious processing of information modeled by the brain, for example, in a dream. In cases where a person encounters a situation in reality perceived at an unconscious level as similar to the previously modeled one, the déjà vu effect occurs.
7. Does a person feel pain when their head is cut off?
Yes, they do. As a result of a medical study in 1983, it was concluded that regardless of how quickly the execution is carried out, when a person loses their head, several seconds of pain are inevitable. Even when using the guillotine, which is considered one of the most "humane" methods of beheading, it is impossible to avoid severe pain, which will last for at least 2-3 seconds.
8. Why can't sleeping people be photographed?
In the 19th century in Europe, there was a tradition of photographing dead people as if they were just asleep. The deceased were dressed in festive clothes, seated in a chair, and photographed for memory. What now causes at least some surprise was considered a common thing at the time. Hence the origin of the superstition - sleeping people in a photo reminded of the deceased, so they shouldn't be photographed.
9. Why is it so hard to win at toy claw machines?
Because the claw manipulator is programmed to only occasionally grasp toys with full force. The owner can set how likely the claw will grip the toy tightly and when it will only slightly grab it. There is also a "reset" parameter in the machine - the owner can set how often the claw will drop an already grabbed toy.
10. Why do we sometimes laugh in inappropriate situations?
When we laugh in an inappropriate environment, such as at funerals, it doesn't mean that we are heartless and disrespecting those around us. It's a sign that our body, under the influence of immense stress, uses laughter to relieve tension. And the giggling we emit when someone falls or otherwise hurts themselves is an evolutionary function that lets the tribe know there's no serious cause for alarm.
