Biography of Archimedes

Biography of Archimedes (mathematician) Archimedes Archimedes, a Greek scientist and mathematician, was born in Syracuse, Greece in 212 BC and went to Alexandria to study at a young age. He spent most of his life in his hometown and was close friends with the ruler of this city.

Here is the most famous bathing done by a human in the history of mankind. The stories say that more than 2000 years ago in Syracuse, the capital of the Greek state of Sicily, then Archimedes, a mechanic and mathematician and adviser to the court of King Yemron, made one of his most famous discoveries. The day he stepped into the public bath and sat in it, and while he was watching the rising water of the bath, a thought suddenly came to his mind. He immediately wrapped a limp around himself and thus And the icon went to the house and kept shouting, “I found it. What did he find?”

The king had given him a mission to discover the secret of the treacherous jeweler in the bar and to expose him. King Heron had doubts about the jeweler and thought that he had taken part of the gold that he had given him to make a royal crown. Biography of Archimedes And he mixed the rest with the metal (silver), which was much cheaper, and made the crown. Although Archimedes knew that different metals had different specific gravity, he thought until then that he had to melt the royal crown. He molded it into a gold bar so that he could compare its weight to that of a pure gold bar, but in this way the royal crown was lost, so he had to find another way to do it on the day he sat in the bath treasury. He saw that the water in the tank came higher and immediately recognized that his body had rejected and moved a certain amount of water in the bath tank.

He hurried back home and began to experiment with this finding. He thought that objects of the same size would move the same amount of water, but if we look at it in terms of weight, a pound of gold is smaller than one. Silver ingots are the same weight (gold weighs almost twice as much as silver) so it has to move less water. This was Archimedes’ hypothesis, and his experiments proved it. He needed a container of water and three weights to do this. He weighed the same weights, which were the crown of the same weight as the pure gold and again the weight of the pure silver. In his experiment, he found that the crown returned more water than the gold bar of the same weight, but this amount of water It is less than the amount of water that the silver ingot carries its weight. Thus, it was proved that the royal crown was not made of pure gold, but a fraudulent and treacherous jeweler made it from a mixture of gold and silver. In this way, Archimedes discovered one of the most remarkable mysteries of nature, which is that the weight of hard objects can be measured with the help of the amount of water they move. This law of “specific gravity”, now called density, is called the Archimedes principle. Even today, after 23 centuries, many scientists still rely on this principle in their calculations.

However, Archimedes had a very high intelligence capacity in mathematics. He invented amazing catapults to defend his lands, which were very useful. He was able to calculate the level and volume of objects such as spheres, cylinders and cones, Biography of Archimedes and a new method for He also developed books on the properties and methods of measuring geometric shapes and volumes, such as a conical curve and a spiral line, a parabolic, a “food” sphere, and a cylinder. He also knew that he had discovered rules about ramps, levers, and center of gravity.

Archimedes has a saying about himself that has remained immortal for centuries, and that is “Give me a foothold, I will lift the earth” The same statement is quoted in another way in Greek literary texts quoted by Archimedes But the concept is the same in both cases. Archimedes, like an isolated eagle, traveled to Egypt at a young age and studied for a time in Alexandria, where he found two old friends, one Conon (this person was a great mathematician whom Archimedes was both intellectually and personally. He had a lot of respect for him) and another was Eratosthenes, who, although a worthy mathematician, was a superficial man who had an extraordinary respect for himself.

Archimedes was in constant contact and correspondence with Conon and shared an important and beautiful part of his works with him in these letters. Later, when Conon died, Archimedes corresponded with a friend who was Conon’s director.

One of Archimedes’ new methods in mathematics was to obtain a number. He calculated a method for calculating the number Pi, that is, the ratio of the circumference of a circle to its diameter, and proved that the bound number is between 3.7 and 10.71. He gave numbers to determine the approximate square root of numbers, and a study of them reveals that he was familiar with interconnected or continuous fractions before Indian mathematicians.

In 1906 J.L. Greek historian and historian Heiberg discovered a valuable document Biography of Archimedes in the city of Constantinople. This document is a book called Mechanical Theorems and Their Methods that Archimedes sent to his friend Eratosthenes. The subject of this book is the comparison of the unknown volume or level of a form with the known volumes and levels of other forms by which Archimedes was able to determine the desired result. This method is one of the titles of Archimedes’ honor, which allows us to consider him as a modern thinker, because he uses everything and anything that could be used in some way to be able to solve problems. The second point that allows us to give the title of modernist to Archimedes is his methods of calculation. Two thousand years before Isaac Newton and Leibniz, he invented the integral calculus and even used a point in solving one of his problems that can be considered as the forerunner of the idea of ​​creating a differential calculus.

Archimedes lived a life of complete tranquility, like the life of any other Biography of Archimedes mathematician who was fully equipped and able to use all his intelligence and genius when the Romans conquered the city of Syracuse in 212 BC. He said that none of his troops had the right to harass, insult and beat this famous and great scientist and thinker. However, Archimedes fell victim to the Roman conquest of Syracuse. He was killed by a drunken Roman soldier, and this was while He was thinking about a math problem in Bazaar Shahr Square. It is said that his last words were: Do not destroy my circles. Thus ended the life of Archimedes, the greatest scientist of all time. The 75-year-old defenseless mathematician passed away in 278 BC.
