Archimedes was born in Sicily in the middle of the Mediterranean in 287 BC. When Archimedes was 11 years old, Phidias sent him to Egypt for further study. When Archimedes was seven years old, his father hired the best teachers for him to teach him mathematics, astronomy, philosophy and literature. Aesop's fables and Homer's epics circulated among the masses are Archimedes' favorite stories. These stories gave him wisdom.

When Archimedes came to Alexandria, Euclid had already died, and his student Eratosthenes became Archimedes' teacher. The relationship between teachers and students is very close. They discuss mathematics, astronomy and mechanics together, watch plays and listen to music together. Whenever the weather is sunny, they also go for a walk or visit the Nile together. It is in this harmonious relationship that Archimedes' knowledge and wisdom are enriched day by day.

Archimedes went to Alexandria to study and work at the age of 11, and didn't return to Syracuse until he was 47, in 24 BC. At this time, his creativity was at its peak, and he was appointed as a consultant to King Heilo, continuing his research in mathematics and mechanics.

In Archimedes's book On the Balance of Planes, which recorded his statics research results, he deduced from a series of axioms that the heaviest mA and mB of objects A and B have the following relations with their distances OA and OB from the fulcrum O, respectively:

mA/mB=OB/OA

This is the famous lever principle. Archimedes appreciated his discovery very much. It is said that he once commented on the role of leverage with such rhetoric: "Give me a stable fulcrum and I will move the earth!" "

one of Archimedes' greatest achievements in the study of hydrostatics was the discovery of the law of buoyancy.

He wrote The Theory of Floating Bodies, a classic work of fluid mechanics. In this book, he proposed: "Any object immersed in water loses the same weight as the water it displaces." In other words: "An object whose density is less than that of water will overcome an upward buoyancy if it is forced to sink. The size of buoyancy is equal to the weight of the water it displaces. " This is the law of buoyancy, also known as archimedes principle. This law is not only applicable to water, but also to all liquids and gases.

Archimedes successfully designed and manufactured a labor-saving water lifting machine: an inclined plane was wound around a shaft to form something similar to the present screw. The screw is placed in a cylinder with two open ends, and one end is provided with a crank which can make the screw rotate. At this time, as long as the lower end of the cylinder is placed in the water, and then the screw is gently shaken, the water will climb along the inclined plane of the thread until it flows out from the upper end of the cylinder. Since then, this kind of machine has been called "Archimedes spiral water lifter". In order to defend the motherland, he devoted all his later years to the research of equipment to resist the enemy, and successively developed weapons such as trebuchet and slewing crane, which defeated the attack of the Roman army again and again.

Due to the power of various weapons invented by Archimedes, the Roman army's attempt to capture Syracuse failed for a long time. Maceiras, the commander-in-chief of the Roman navy, said gloomily after many defeats that Archimedes, a "geometric monster", made a fool of us.

Archimedes used his wisdom to light up the wild sky and make the dawn of civilization shine on the land of Europe. He is like an innocent child, immersed in the soaring of science, unaffected by fame and fortune, and even the shadow of death can't block the great joy and happiness of devoting himself to science.
