Inspirational story of scientists: Einstein
Albert. Einstein was born in a Jewish family in Germany on 1879. He is the greatest physicist in the 20th century, the standard-bearer of the scientific revolution, and one of the most creative and intelligent figures in human history. He created four fields of physics in his life: special relativity, general relativity, cosmology and unified field theory. He is one of the main founders of quantum theory and has also made great contributions to the theory of molecular motion and quantum statistics.
Einstein's contribution to scientific thought may be comparable to that of Newton and Darwin in history. At the same time, Einstein showed great concern for social progress and human destiny, and opposed the war of aggression, militarism and fascism, national oppression and all kinds of racial discrimination, and waged an indomitable struggle for it.
Throughout Einstein's life, we can say that he is not only a great scientist, a thinker with philosophical exploration spirit, but also a world citizen with a strong sense of justice and social responsibility. He advocated rationality all his life, and made efforts to make science benefit mankind, integrating truth, goodness and beauty.
1995 April 18, Einstein died in the United States. According to his will, no activities will be held, no monument will be erected, and the ashes will be scattered in a place that will always be kept secret, and no place will be sacred.
Inspirational stories of scientists: Fleming and penicillin
Fleming was born in Yard, Scotland. His father is an industrious and honest farmer and has given birth to eight children. Fleming is the youngest. Due to the decline of his family, he could not complete higher education and had to come out to make a living at the age of sixteen. When I was twenty years old, I inherited an inheritance from my aunt, and then I could continue my studies. After graduating from medical school at the age of 25, he has been engaged in medical research.
1928, Fleming gave a lecture on bacteriology at the University of London, and accidentally found that mold has bactericidal effect. This mold looks like a brush under the microscope, so Fleming called it "penicillin" because it has fine hair. From then on, Fleming made a systematic study on penicillin, and it was not until 1938 that penicillin was officially used in patients. During World War II, penicillin saved countless lives.
Fleming is a down-to-earth person. He doesn't just talk, but works silently. At first people didn't take him seriously. When he worked in the laboratory of St Mary's Hospital in London, many people there called him Little Frye to his face, laughed at him behind his back and nicknamed him "Scottish Antique".
One day, Sir Wright, the director of the laboratory, presided over a routine business seminar. Some experimenters are eloquent and grandstanding, but little Frye has been silent. Sir Wright turned his head and asked:
"Little Frye, what do you think?"
"Do it." Little Frye only said one word. What he means is that instead of talking nonsense like this, it is better to resume the experiment at once.
At five o'clock in the afternoon, Sir Wright asked him again:
"Little Frye, do you have any comments now?"
"tea." It's time for tea.
On this day, little Frye only said these two words in the laboratory.
Fleming carefully observed the glass jar for cultivating grape ball bacteria as usual.
"Alas, the green mold has run into the jar again!" Fleming frowned.
"Strange, around the green mold, how no grape ball bacteria? Can it stop the growth and reproduction of bacteria? " Careful Fleming never let go of a suspicious phenomenon and thought hard.
He did some research and proved that this green mold is an effective substance for sterilization. He gave this substance a name: penicillin. With this discovery, human beings have regained many lives from death.
The story of bell invented the telephone
Nowadays, the telephone has entered thousands of households. Do you know who invented the telephone?
Bell is the man who invented the telephone. He was born in England on 1847. When he was young, he and his father taught the deaf together. He once wanted to make a machine to let deaf people see sound with their eyes.
1873, Bell, who became a professor at Boston University in the United States, began to study the device of transmitting multiple telegrams on the same line-multiplex telegrams, and he sprouted the idea of using electricity to transmit people's voices to far places and let people thousands of miles away talk face to face. So bell began to study the telephone.
That was June 2nd, 1875. Bell and his assistant Watson are experimenting with multiple telegrams in two rooms respectively. An accidental accident inspired Bell. In Watson's room, there is a spring stuck to the magnet of the telegraph. When Watson pulled it away, it shook. At the same time, Bell was surprised to find that the spring on the telegraph in his room vibrated and made a sound. It is the current that transmits vibration from one room to another. Bell's mind suddenly broadened. He thought: If a person speaks to a piece of iron, the sound will cause the iron to vibrate; If an electromagnet is placed behind the iron sheet, the vibration of the iron sheet will inevitably produce large and small currents in the electromagnet coil. This fluctuating current travels far away along the wire, so won't the same vibration and sound appear on similar equipment in the distance? In this way, the sound travels far away along the wire. Isn't this the dream phone!
Bell and Watson made the telephone according to this new idea. In an experiment, a drop of sulfuric acid splashed on Bell's leg, causing him to shout, "Mr. Watson, I need you, please come to me!" " "This sentence reached Watson's ear by telephone through wires, and the telephone succeeded! 1On March 7th, 876, Bell became the patentee of telephone invention.
Bell obtained 18 patents in his life and 12 patents in cooperation with others. He envisions burying telephone lines in the ground or hanging them in the air, and connecting them to houses, villages and factories ... so that you can make phone calls directly from anywhere. Today, Bell's vision has become a reality.
The story of madame Curie
Madame Curie was a French-born Polish scientist who studied radioactivity and won the Nobel Prize twice in her life. Mary has been studying very hard since she was a child. She has a strong interest in learning and special hobbies. She never misses any learning opportunities easily, and shows tenacious enterprising spirit everywhere. Since primary school, she has been the first in every subject. 15 years old, graduated from high school with a gold medal. Her father studied physics at St. Petersburg University earlier, and her thirst for scientific knowledge and strong enterprising spirit also deeply nurtured little Mary. She likes all kinds of instruments in her father's laboratory since she was a child. When she grew up, she read many books on natural science, which filled her with fantasies. She is eager to explore the scientific world. But her family at that time did not allow her to go to college. /kloc-started to be a tutor for a long time at the age of 0/9, and at the same time taught himself various courses to prepare for future study. In this way, until the age of 24, she finally came to study at the Faculty of Science of Paris University. With a strong thirst for knowledge, she listened carefully to every class. Hard work has made her worse and worse, but her academic performance has always been among the best, which not only envied her classmates, but also surprised her professors. Two years after entering school, she confidently took the Bachelor of Physics exam, ranking first among 30 candidates. The next year, she won a bachelor's degree in mathematics with the second place.
Darwin's story
When Darwin was young, he once went to the garden with his mother to cultivate young trees. His mother said, "Soil is a treasure, and young trees can only grow with soil. Don't underestimate this soil, because it grows grass, fattens cattle and sheep, and gives us milk to drink and meat to eat; It grows wheat and cotton, so we can have food and clothes. The soil is so precious. "
Darwin asked, "Mom, can that soil grow puppies?"
"I can't!" Mother smiled and said, "The puppy was born by a dog mother, not a native."
Darwin asked again, "I was born to my mother, and my mother was born to my grandmother, right?"
"Yes! All the people were born to his mother. "
"Who gave birth to the earliest mother?"
"It's God!"
"Then who was born of God?"
Mom can't answer. She said to Darwin, "children, there are many things in the world that are mysteries to us." Please grow up like a small tree. These mysteries are waiting for you to solve! " "
Darwin liked flowers, trees, birds, insects and fish since he was a child. After school, he still maintains a keen interest in nature. He rode horses, hunted, fished, collected minerals, caught insects, and went into the Woods to observe the habits of birds. For Darwin, the whole world is a big question mark, and there are too many things to explore and think about. He often meditates while observing, even forgetting the danger. Once, Darwin was walking in an old castle. As usual, he was lost in thought. He walked slowly and absently, suddenly stepped on the air and fell off the battlements. At this time, Darwin was very sober and his mind was still thinking.
: The Story of Joule
Joule, a famous British scientist, loved physics since he was a child. He often does some experiments about electricity and heat by himself.
One holiday, Joule and his brother traveled to the suburbs. Joule, who is clever and studious, never forgets to do his physics experiments even when he is playing. He found a lame horse, led by his brother, hiding behind him quietly. He used a volt battery to electrify the horse, trying to see how the animals would react after receiving the current. As a result, the reaction he wanted to see appeared. The horse jumped wildly after being shocked and almost kicked its younger brother.
Although the danger has appeared, it has not affected the mood of little Joule who loves to do experiments. He and his brother rowed the boat to the lake surrounded by mountains, where Joule wanted to try the echo. They filled the musket with gunpowder and then pulled the trigger. Who knows "bang", a long flame spouted from the muzzle and burned Joule's eyebrows, almost scaring my brother into the lake.
At this time, the sky was covered with thick clouds, lightning and thunder. Joule, who just wanted to go ashore to take shelter from the rain, found that it took a long time to hear the thunder after every lightning. What happened? Joule didn't take shelter from the rain, dragging his brother up a hill and carefully recording the time of lightning and thunder with his pocket watch. After school started, Joule almost wanted to tell the teacher all the experiments he had done and ask for advice from the teacher. The teacher smiled at Joule, who was eager to learn and curious, and patiently explained to him: "The speed and harmony of light are different. The speed of light is fast and the speed of sound is slow, so people always want to see lightning before hearing thunder, but in fact lightning and thunder happen at the same time. "
Joule suddenly realized. Since then, he has been more fascinated by learning scientific knowledge. Through continuous study and careful observation and calculation, he finally discovered the mechanical equivalence of heat and the law of conservation of energy, and became an excellent scientist.
