Move the earth. "He devoted his life to the scientific research of volume and buoyancy, and one of them
The interesting story is that when the king asked the goldsmith to build a pure gold crown, the king because
If you suspect that the goldsmith added sundries, please ask Archimedes for identification, which Archimedes has been thinking about.
Method: He went into the bathtub to take a bath and didn't realize it until he saw the water overflowing.
The principle of the product, he happily ran out of the bathroom and shouted: "I found it!" " "Forget it at the moment.
I'm naked! In addition, Archimedes also made mathematical achievements in geometry!
Archimedes was the first engineer to talk about science. In his research, he used Ogilvy.
The rational method, first assuming, and then drawing the result through rigorous logical reasoning, he has been looking for.
Find general principles and apply them to special projects. His works always blend mathematics and physics.
Richard, so Archimedes became the father of physics.
He applied the lever principle to the war, and his deeds of defending silas pigeons are widely known.
He also used the same principle to derive the volume of some spheres and the volume of the rotator (ellipsoid, back).
Parabola, hyperboloid of revolution), in addition, he also discussed archimedean spiral (for example:
The trajectory left by flies flying outward from the center of a turntable rotating at a constant speed), circular, spherical,
In ancient times, the related principles and achievements of cylinders were unparalleled.
Archimedes effectively used the concept of method put forward by Ogilvy, and he proposed that
A circle circumscribes a polygon, and a similar circle circumscribes a polygon. When the number of edges is large enough, two polygons
The circumference approaches the circumference from top to bottom. He used hexagons first, and then
Double the number of edges one by one to get a polygon with 96 edges, and the estimated value of π is between 3. 14 163 and 3. 14286.
In addition, he calculated that the surface area of the ball is four times that of the maximum inscribed circle. He got the most.
Italy's masterpiece is to deduce that the volume of a ball inscribed in a cylinder is two-thirds of that of a cylinder. This decision
The reason is engraved on his tombstone, which has become his immortal great annotation.
Pythagoras was a Greek philosopher and mathematician. Born in Greece
Samoan aristocratic families studied in Egypt and Babylon when they were young.
I studied mathematics and traveled to two ancient civilizations with high cultural level in the world at that time. Bidag
Lars later went to southern Italy to teach mathematics and publicize his philosophy. Later,
His followers formed a political and religious group called Pythagoras School.
Pythagoras is a little better than some scholars who opened the altar to give lectures in his contemporaries; because
He allows women (expensive women, of course, not handmaiden) to attend classes. He thinks that women
Women and men are equal in the right to seek knowledge, so he has more than ten schools.
A female scholar. This is a phenomenon that no other school has.
Legend has it that he is a very good teacher. He thinks everyone should know some geometry knowledge.
Once he saw a poor man who worked hard. He wanted to teach him geometry, so he was very interested in this man.
Suggestion: If this person can learn a theorem, give him a coin. This man
I learned geometry from him for money, but after a while, the student was not interested in geometry.
Had a great interest, but asked Pythagoras to teach faster, and suggested:
If the teacher teaches one more theorem, he will give a coin. It won't be long, Bida.
Goliath took back all the money he had given to his students before.
Pythagoras died in Cordona, Italy. In the urban riots,
He was assassinated. His tomb is still in the ancient mountain city of Italy, and this tomb is
Like the steamed bread grave in China. More than 2000 years later, this tomb is still preserved, which shows that people
Pay attention to this scholar.
Pythagoras founded the Pythagorean Brotherhood, and integers and fractions were regarded as idols. They realized that
In order to reveal the mysteries of the universe through logarithmic understanding and make them closer to God, the fact is that
Religious organizations. When you join the club, you must swear not to disclose your mathematical findings.
After his death, some members disclosed that the regular 12 polyhedron can be composed of 12 regular pentagons.
Now he was forced to drown. They focus on the study of natural numbers and rational numbers, especially
A perfect number is the sum of its positive factors (except itself), for example, 6= 1+2+3,
28= 1+2+4+7+ 14。 They think that God chose to create in 6 days, because 6 is perfect.
Everything, and the moon goes around the earth for about 28 days.
Shortly after the Pythagorean Brotherhood was founded, Bishop wrote The Philosopher.
When taking part in an Olympia competition, Prince Leon of Fleutre asked him what would happen.
Describing himself, he replied, "I am a philosopher." He explained: "Some people have it.
The love of wealth and being controlled make some people blindly follow, because of their enthusiasm for power and rule, but the most
Excellent people devote themselves to discovering the meaning and purpose of life itself. He tried to reveal the essence.
A man who is mysterious and loves knowledge is a philosopher. 」
"In a right triangle, the square of the hypotenuse is the sum of two squares."
Long before Bi put it forward 1000 years ago, China people (Zhou Shanggao) and Babylonians used it.
But most people still owe the theorem to Pythagoras because he proved the universality of the theorem.
Bi believes that finding proof means finding knowledge, and this knowledge has accumulated more experience than any training.
There is no doubt that mathematical logic is the arbiter of truth.
Bi seldom makes public appearances. Although he teaches students mathematics and philosophy, he never allows it.
Many students make rumors, and it is also because the Brotherhood has concealed its mathematical findings that it has gradually attracted the attention of residents.
Fear, delusion and doubt. Later, because the school was involved in political events, it was related to the school's position in Croton.
The conflict between the administrative authorities eventually led residents to destroy the school. At the age of 80, I finished in one night.
Believers who were killed in the riots and fled abroad continued to spread their mathematical truth.
For Pythagoras, the beauty of mathematics is that rational numbers can explain all natural phenomena.
This guiding ideology makes Bi turn a blind eye to the existence of irrational numbers, and even
Result in that execution of one of his students. The student's name is hippasus. Out of boredom, he
Trying to find the equivalent score of root number 2, he finally realized that there was no such score at all.
That is to say, the root number 2 is irrational. Hippasus was overjoyed at this discovery, but
His teacher Bishop is unhappy. Because Pythagoras explained everything in the world with rational numbers,
The existence of irrational numbers will arouse doubts about his beliefs. Hippasus got it through insight.
This result must have been discussed and scrutinized for a period of time, and Bi should have accepted this new one.
Digital source. But never put off till tomorrow what you can has been reluctant to admit his mistake, just logic.
Reasoning overturns hippasus's argument. To his lifelong shame, he actually sentenced
Hippasus drowned. This is the greatest tragedy of Greek mathematics, and irrational numbers only appeared after his death.
Discuss it safely. Later, Euclid proved that the root number 2 is
irrational
