'Life's' works through dreams

The dream always contains many unsolved mysteries, in which many dreams seem to be related to the future.

In the past, many scientists and writers partly thanks to the dream of giving works to life.

Dmitri Mendeleev and the periodic table

Dmitri Mendeleev (1834-1907) then cherished the idea of ​​systematically arranging 65 chemical elements.

Mendeleev chemist (1834-1907).

Mendeleev also predicted that the elements would sort by atomic mass but could not shape a clear table.

"In a dream, I saw a table of naturally arranged elements. Waking up, I immediately wrote down," Mendeleev's quote was quoted by Russian chemist Bonifaty Mikhailovich Kedrov (1903-1985). in the work On the Question of Scientific Creativity.

Periodic table of chemical elements in 1871.

Mendeleev also predicts some of the properties of unknown elements in hopes of filling his periodic table.

Later, the periodic table expanded based on the discovery and synthesis of new elements and the development of new theoretical models.

Niels Bohr and atomic model

Niels Bohr (1885-1962).

Niels Bohr (1885-1962) was a Danish physicist who was awarded the Nobel Prize in Physics (1922) thanks to the famous atomic modeling work.

According to Edwina Portocarrero from the Massachusetts Institute of Technology, Bohr shared that he once dreamed of sitting on the Sun while all the planets flew around on a small rope.

When he woke up, he successfully studied an atomic model consisting of a small nucleus with a positive charge and electrons moving around on different orbits, similar to the solar system structure, with only the gravitational force. lead is replaced by electrostatic force.

Elias Howe and sewing machine

Elias Howe and the sewing machine precursor to today's machines.

Elias Howe name (1819-1867) associated with sewing machine. Although he was not the inventor of the sewing machine, he was the one who greatly improved the sewing machine and received US patents.

In his dream, Elias Howe was asked to build a sewing machine for a fierce king in a foreign country with a 24-hour deadline, otherwise he would be executed. Unable to complete, Howe was executed by soldiers holding spears pierced through his head.

After that, Elias Howe woke up and started working immediately. Howe designed a curved needle, placed the needle hole at the tip - previously placed at the needle base - and combined with the bobbin to create the seam.

Albert Einstein and the speed of light

Einstein's childhood.

"Einstein said that his entire career was a reflection from a past dream," honoring John H. Lienhard, GS in mechanical and historical engineering at the University of Houston (USA). on the Engines of Our Ingenuity radio show.

As a young man, Einstein dreamed himself to ride on a sleigh slipping very fast. When Einstein and the car moved close to the speed of light, all colors mixed into one.

After waking up, he spends most of his time thinking and researching what happens at the speed of light.

Kekulé and benzene ring

The benzene circle was a mystery to scientists.

Benzene is an organic compound discovered by British scientist Michael Faraday (1791-1867) in 1825 but after a few decades, its structure has not been understood.

Scientists know that the benzene structure is very symmetrical but it is unimaginable how 6 valence of 4 valence atoms and 6 hydrogen valence atoms arranged in a symmetrical way.

In 1865, Friedrich August Kekulé (1829-1896), a German chemist, sat and slept beside the stove while working tirelessly. In the dream, he saw carbon and hydrogen atoms connected and danced into a chain along with an image of a snake turning its head around its tail and spinning in front of it.

Kekulé wakes up and understands that it is the structure of benzene: the hexagon with each vertex is a carbon atom.

Otto Loewi and nerve pathways

Otto Loewi (1873-1961).

The night before Easter in 1921, Otto Loewi (1873-1961), the sleeping Austrian creature suddenly woke up to take notes and then lay down to sleep again, not knowing what he was drawing.

The next day, while sleeping, the idea just came back. This is an experimental method that can be used to prove whether the hypothesis Loewi made 17 years ago is correct.

Loewi immediately taught and rushed to the lab, removed two frog hearts with physiological saline, a heart retaining nerve number 10, the second fruit did not have nerve number 10.

He used electrodes to stimulate the number 10 nerve of the first heart to slow the heart. After a few minutes, bring the first heart-soaking solution into the device containing the second heart.

Describe Loewi's experiment - (Photo: Important7).

As a result, the second heart also began to inflate, confirming that neurons can communicate with each other by releasing chemicals. Thanks to this discovery, Loewi received the Nobel Prize for Medicine in 1936.

Mary Shelley and Frankenstein novels

Writer Mary Shelley.

Mary Shelley (1797-1851) is an English writer, famous for her novel Frankenstein and wife of romantic poet Percy Shelley (1792-1822).

During a vacation with her husband and poet Lord Byron (1788-1824) and writer John Polidori (1795-1821) on Lake Geneva, Switzerland, Byron set up a horror story writing competition between four people.

Later, on a rainy night, Mary dreamed of a scene of a student kneeling in front of an object shaped like a man but the parts were assembled from different bodies. This was the idea for Frankenstein to be born, accepted by Mary at the age of 18 and completed in 20.

The drawing depicts the book in the 1831 edition of Theodor von Holst.

Frankenstein is the story of the student Victor Frankenstein creating an organism from the dead man's organs, making this creature alive but then chasing his "brainchild" .

The hatred makes the creature decide to take revenge by killing Frankenstein's wife and then killing his own creator.

Later, many plays and films were inspired by Mary Shelley's classic novel.
