Knowledge is power. In this series, we collect for you fascinating and sometimes surprising facts about the world around us. We hope that they will be for you not only interesting, but also practically useful.
Great inventors – people who invented things or made a discovery without which today we can not imagine our life. Their names are taught to students in the classroom, their lives and studies are an example for many of us. But this does not mean that the way these people for recognition was easy and straightforward. In this article, we present a few of curious, instructive and even tragic facts from biographies of great scientists of the past.
1. Creator of Vaseline ate a spoonful of the substance each day and lived 96 years
Robert Chesebrough (1837 – 1933)
Robert Chesebrough began his career with an attempt to obtain kerosene from sperm whales. However, then Robert began to study oil and products from it. Communicating with oil, Robert became interested in sticky oil product – paraffin-shaped mass that stuck to the drilling rigs and and clog up pumps.
On its basis, Chesebrough invented Vaseline, which began to sell as the healing cure for burns and wounds.
Sales of Vaseline went not too actively, and therefore the inventor went to tour across America. During lectures Robert poured acid on his hand, put cuts, and then smeared with wonderful Vaseline. Before his death (as he lived, as indicated above, for a long time), Robert admitted that so believed in the healing capabilities of Vaseline that ate each day a spoonful of this product.
2. Thomas Edison killed elephant by electric shock
Thomas Edison (1847 – 1931)
Thomas Edison – one of America’s most successful inventors and entrepreneurs. And many detractors argue that the second quality he was much more developed than the first. Edison went to any actions to push his developments and “drown” competitors.
For example, against Nikola Tesla, who suggested using alternating current instead of DC, Thomas Edison turned the whole information war. In its course even innocent elephant from the local zoo was hurt. During a public experiment elephant was killed by an electric shock to prove the danger of alternating current health.
3. Stephen Hawking could utter only one word per minute
Stephen Hawking (1942)
Hawking is considered to be a remarkable scholar and a great popularizer of science.
Everyone knows that he is seriously ill, but that does not prevent him to lead an active life, to write books, to take part in the scientific and popular films.
Due to the complete paralysis, he could only manage a single muscle on a cheek.
However, few people know the difficulties that involves such activities. Due to the complete paralysis, he could only manage a single muscle on a cheek. Movement of the muscles are fixed with a special sensor. This sensor controls the computer cursor, allowing him to communicate with others.
4. Rudolf Diesel committed suicide because of the lack of funds and recognition
Rudolf Diesel (1858 – 1913)
Rudolf Diesel immortalized his name for the famous engine, which he invented. Diesel applied for a patent for a “new rational heat engine” in 1892, and five years later created the first fully working samples.
While everyone almost immediately became clear that the new design is unique in terms of efficiency, the introduction of the engine passed with great difficulty. Diesel was a bad businessman, and the initial patent war undermined his health and financial situation.
His death is still shrouded in mystery.
September 29, 1913, Rudolf Diesel on the steamship “Dresden” sailed from Antwerp to London for the opening of a new plant. However after he went to the cabin in the evening, more nobody saw him.
In ten days the Belgian fishermen found a body of well dressed man in the sea. They drew contents of body pockets and threw out in the sea. Subsequently relatives identified a wallet and Rudolf Diesel’s decoration.
5. Marie Curie’s things and manuscripts even today are dangerous
Marie Skłodowska Curie (1867 – 1934)
Marie Skłodowska Curie received the Nobel Prize in physics for the discovery of radium and polonium, as well as the study of radioactivity. These studies were not in vain for her health and Marie Curie received a severe form of radiation sickness from which subsequently died.
Personal belongings of the scientist, her furniture, books, laboratory records, etc. are stored in the National Library of France in the lead boxes protected from the strong radiation. To see them, you must obtain a special permit and sign a disclaimer.
6. René Laennec invented the stethoscope, not to touch the breasts of women
René Laennec (1781 – 1826)
Each of you familiar with stethoscope – medical instrument for listening to the noise of human internal organs. Before the advent of the stethoscope, the doctor just put his ear to the patient and listened to the lungs, heart, intestines.
But the French doctor René Laennec thought this procedure is not too decent, especially when it was necessary to examine young girls.
To do this, he began to use a collapsed piece of paper. Later, he found that this method is much better conveys sounds, and after several years of experiments presented the design of the stethoscope.
7. The last words of Albert Einstein had not been translated
Albert Einstein (1879 – 1955)
The final stage of his life, Albert Einstein spent in the US, where, almost to the very last day, he conducted research, taught and participated in public life.
In 1955, his health deteriorated rapidly, and he was placed under constant medical supervision. Before his death, Einstein said a few words in German, but the American nurse did not understand them, and then could not say these words. Therefore, no one knew that the great scholar said in the last minute.
