Even more amazing is the lever principle he proposed: to make the lever balance, the power arm is several times the resistance arm, and the power is a fraction of the resistance. The discovery of this principle was also attributed to the king at that time.

According to legend, the king of Syracuse built a ship for King Ptolemy of Egypt, but because the hull was too big and heavy to put into the sea, the king threw the problem to Archimedes: "Since you claim to be able to pry up the earth, you should be able to put a ship into the sea?"

For ordinary people, the heart has long beeped the dog, but the eighteen martial arts in the body Archimedes was afraid of who.

He asked the craftsmen to install a set of elaborate tackles and levers on the front and back of the ship, and then had more than 100 people grab a rope in front of the ship, and the ship slipped slowly into the sea. The king was dumbstruck for a moment, and even more impressed by Archimedes' ingenuity.

Even sitting down and quietly doing research can beat the average scientist by a mile.

Archimedes had brilliant achievements in mathematics, especially in geometry. He made effective use of Euclid's concept of convergence.

For example, using the "approximation method" to calculate the area of the ball, the volume of the ball, the parabola, the area of the ellipse, later mathematicians based on such "approximation method" to develop into the modern "calculus".

In addition, he used the circle cutting method to find the value of π between 3.14163 and 3.14286, and studied the properties of the spiral curve, the current "Archimedes spiral" curve, named in his honor.

He had great foresight in astronomy. He not only used water power to make a celestial instrument that could predict lunar and solar eclipses, but also doubted the "geocentric theory" generally accepted at that time in his later years, and speculated that the Earth might rotate around the sun, but this conjecture was not put forward for discussion until the Copernican era.

However, although Archimedes was a scientist who did not usually play with swords, in fact, he was a top player of giant machines.

At that time, in Europe, in engineering and daily life, often use some simple machinery, such as: screws, tackles, levers, gears, etc. Archimedes spent a lot of time to study and found the concept of "moment".

Attaching importance to experimentation, he designed and manufactured many instruments and machinery throughout his life, such as weightlifting pulleys, water lifters and military stone throwers.

"Scholars die at the podium, generals are wrapped." It is the pursuit of another perfect death, and for Archimedes, as a scholar with lofty ideals, to die in the research he was doing was both a defect and a fulfillment.

Archimedes' death is full of drama. He used the principle of leverage to build a batch of trebuchet, which effectively stopped the Roman siege of the city; They invented something like a crane, so that the Roman navy couldn't get anywhere near Syrah. Even summoned soldiers, holding special large mirrors, using optical principles to burn enemy warships.

He was praised by the Syracuse as "the warrior who defended his home" and "the man of God who stood alone against the Roman army" in the enemy's heart, but no one expected that this brilliant genius would one day die in battle.

At that time, Roman consul Marcenus led an army to fight for the strategic city of Syracuse. After three years of repeated frustration with Archimedes' invention, he attacked on the night of Artemina's carnival, and out of pity, he ordered his officers not to harm Archimedes.

After entering the city, the Roman soldiers did not go straight to the palace, but everywhere to search for Archimedes. Later, a Roman soldier burst into Archimedes' bedroom and found him drawing pictures on the floor. The long campaign cost Archimedes a lot of time, and he had to work overtime to spare some scientific research time, and stayed up all night to verify a geometric problem.

The soldier saw all the figures on the ground and shouted at the old man, "Are you Archimedes?" Perhaps the deduction was too focused, Archimedes ignored it and went on with his work. However, this persistent attitude angered the soldier who had suffered so much that he forgot his command and stabbed Archimedes' body with a sword.

By the time Marsinus got the news, it was too late, and he had to punish the soldiers who had disobeyed the order, collect Archimedes' body, and in accordance with his long-cherished wish, engraved on his tombstone the cylinder and its inner cut ball as an epitaph, to show the memory of this genius.

However, either because the literature is incomplete or because Archimedes is so legendary, there have been different versions of his death.

The only thing that is certain is that the Syracuse people did not appreciate this genius, and as time passed, Archimedes' tomb was quickly buried under the grass.
