25 most interesting things that aren't taught in school these days
Anonim

There is an infinitely huge number of things in the world that not only surprise, but amaze the imagination. A certain Today I Learned subreddit was even created. This is the place where people go to get their daily dose “Oh, I didn't know that! How amazing!". Users are constantly there sharing random but interesting facts that they just discovered. There you can find the most curious information about everything in the world. The collection contains the most popular and interesting messages to date.

1. Books are a source of knowledge, and knowledge is power

Of course, this may not be exactly the information that should be included in the textbooks. But they, no doubt, can expand your horizons and understanding of the world as a whole. By the way, did you know that paper books are still far superior to electronic books, even among young people?

Paper books continue to lead the digital age

If you read these facts more than once, it is difficult to remember them for life. It would be convenient to retrieve them from memory only when needed. In fact, in practice, most of what we learn goes into one ear and flies out into the other. Scientists say that in just an hour, if we do nothing with new information, we will forget about 50% of what we have learned. In a day, this number will rise to 70%. If a week passes, and this information is not used, then 90% will be forgotten.

2. The most extravagant neuroscientist

Rita Levi-Montalcini, Italian neuroscientist, 1986 Nobel Prize winner in Physiology or Medicine

After being fired in 1938 from the anatomy department of her university, Rita Levi-Montalcini set up a laboratory in her bedroom. She studied the growth of nerve fibers in chicken embryos. This work led to the discovery of the nerve growth factor, for which Levi-Montalcini was awarded the Nobel Prize in 1986.

In fact, we need to do a little more than just scroll and read to keep everything we learn in memory. Marianne Stenger, a London-based freelance writer and journalist with extensive experience who has studied all aspects of learning and development, says: "We can use absolutely any method to anchor new information in our minds."

For this, the use of visual aids, participation in group discussions (write comments on social networks!) Will also work. You also need to apply new knowledge in practice, look for opportunities to teach others. Correlation of new material with what you already know will also help. It is very helpful to make an effort to retrieve information from memory. To do this, you need to read aloud and write down brief information about what you read. So there will be much more chances to keep in mind what you have learned for a long time.

3. Ravens and wolves

Are wolves and crows friends?

Wolves and crows have a symbiotic relationship. Birds can lead wolves to prey, so that later they can take some of the remains. They will tease forest predators and provoke a chase. Sometimes even they can develop something like friendship.

Scientist bacteriologist, immunologist and epidemiologist, Valdemar Aronovich Khavkin. Creator of the first vaccines against plague and cholera

In 1896, Bombay was struck by an epidemic of the bubonic plague. The Indian government has turned to Waldemar Hawkin, the developer of the first cholera vaccine, for help.

He devoted himself entirely to science.

A Turnaround in the History of Nuclear Science

The Soviet Union realized that the Americans and the British were developing an atomic bomb. This happened after it was noticed that Western scientists stopped all publications on the topic of nuclear science. As a result, the only correct conclusion was made: nuclear science has become a state secret. The Soviets then began developing their own nuclear program.

20. An unexpected property of snow

Winter landscape

Snow is not just a beautiful and healthy natural phenomenon. He is also able to absorb sound. This is because snow is porous. Snowflakes are six-sided crystals filled with air. They are able to absorb sound waves, creating a certain calming effect under the snow cover.

21. Ancient science was superior to ours

Eratosthenes

The ancient Greek scientist, mathematician and astronomer, Eratosthenes, who lived in the 3rd century BC, was able to measure the circumference of the Earth.

23. Why are we sick?

Influenza virus

During the winter, people traditionally spend more time in enclosed spaces that are poorly ventilated. Because of this, it turns out that they breathe the same air as patients with the flu. This makes the infection easier. Also in winter, days are shorter and lack of sunlight leads to low levels of vitamin D in the body. This, in turn, lowers immunity to the virus.
