Archimedes was an ancient Greek inventor and mathematician, celebrated as one of the greatest minds in history. His work laid the foundation for many scientific and engineering advancements. Although he loved studying geometry, he also invented war machines that protected his city, Syracuse, from Roman invaders. Let’s explore the fascinating life and achievements of Archimedes, whose legacy has endured for thousands of years.
Archimedes was born in 287 BC in Syracuse, a city on the island of Sicily. His father, Phidias, was a well-known mathematician and astronomer. After finishing his early education in Sicily, Archimedes traveled to Egypt to study further. Alexandria, a city in Egypt, was famous for its educational opportunities at the time. Some historians believe Archimedes might have been related to King Hieron II, the ruler of Syracuse.
When Archimedes returned to Syracuse, he brought with him the “Archimedes Screw,” a device that could move water uphill. This invention was incredibly useful for irrigation and is still used today. Although little is known about his personal life, stories of his achievements have been passed down through generations.
One of the most famous stories about Archimedes involves a golden crown. King Hieron suspected that a goldsmith had cheated him by not using pure gold for a crown. He asked Archimedes to find out if the crown was pure without damaging it. While taking a bath, Archimedes realized that he could use the water displacement method to determine the crown’s density. Excited by his discovery, he reportedly ran through the streets shouting “Eureka!” meaning “I have found it!” This led to the Archimedes Principle, a key concept in physics related to fluid mechanics.
King Hieron often challenged Archimedes to create extraordinary things. One such project was building a massive ship called The Syracusia. Archimedes used his knowledge of buoyancy to ensure the ship could float. He also invented the Law of the Lever and famously said, “Give me a place to stand, and I will move the Earth.” He demonstrated this by lifting a ship using a lever system.
Archimedes made significant contributions to mathematics. He calculated the value of Pi and explored the volume and surface area of various shapes. His systematic use of mathematical proofs laid the groundwork for future scientific research.
In the 3rd century BC, the Mediterranean region was divided between the Carthaginians and the Greeks, with Rome looking to expand its territory. After the First Punic War, Sicily became a Roman territory. King Hieron II kept peace with Rome, but after his death, Syracuse faced a Roman invasion.
Despite being in his 70s, Archimedes invented war machines that defended Syracuse for two years. These included the Archimedes Claw, which could lift and capsize Roman ships, and powerful catapults. He was also credited with using mirrors to focus sunlight and set Roman ships on fire. However, in 212 BC, Syracuse fell to the Romans, who admired Archimedes’ genius and wanted to protect him.
After Syracuse was captured, a Roman soldier accidentally interrupted Archimedes while he was working on mathematical drawings. Annoyed, Archimedes reportedly said, “Do not disturb my circles!” before being killed. He was 75 years old.
Archimedes was buried in a tomb that celebrated his mathematical achievements, featuring a sphere and a cylinder. Although many of his original works were lost, some were preserved over time. In 1906, a manuscript known as the Archimedes Palimpsest was discovered, containing some of his lost works, which were later restored and made available to the public.
Archimedes’ contributions to mathematics, science, and engineering have had a lasting impact on the world. His legacy continues to inspire modern thinkers, and without his brilliance, our world would be very different.

Archimedes was the ancient Greek inventor and mathematician who is remembered for being one of the greatest minds in all of human history. His theorems became laws of physics, and his equations became essential for future generations of scientists and engineers. While his great passion in life was the study of geometry, Archimedes also used his mind to invent weapons of war that successfully defended the city of Syracuse from Roman invaders. On today’s Biographic, we tell the story of a man whose legacy has lasted thousands of years.
**A Life of Academic Achievement**
Archimedes was born in 287 BC in the city of Syracuse, located on the east coast of the island of Sicily. He was the son of Phidias, a renowned mathematician and astronomer. After completing his basic education in Sicily, Archimedes traveled to Egypt to further his studies. At that time, the city of Alexandria was known for being one of the greatest places to receive an education in the world. Many scholars believe that he may have been descended from nobility, possibly a relative of King Hieron II, the ruler of Syracuse at that time.
Upon returning to Syracuse, Archimedes brought with him the invention known as the “Archimedes Screw.” Scholars believe he may have borrowed the idea from existing devices in Egypt, but his adaptation revolutionized life for the people of Syracuse. This spiral-shaped device could be placed into a river or ditch, allowing water to be moved uphill, making it easier to fill buckets or drain wells. The Archimedes Screw is still used today for irrigation.
Aside from his achievements, little is known about Archimedes’ personal life. He shared details with his friend and biographer, Heracleides, but the text was lost over time. We don’t know if he was ever married or had children, but stories of his achievements have been passed down through the years, some of which are debated by historians.
According to the Greek biographer Plutarch, Archimedes was so focused on his work that he often neglected his basic needs. He would forget to eat and bathe, becoming completely absorbed in his studies.
**The Golden Crown**
One of the most famous stories about Archimedes is that of the golden crown. This tale was recorded by the Roman architect Vitruvius in the first century BC, based on oral traditions. A local goldsmith in Syracuse was commissioned to create a golden crown, but King Hieron suspected it was not made of pure gold. He tasked Archimedes with determining its authenticity without damaging it.
Obsessed with the problem, Archimedes struggled to find a solution until he made a breakthrough while bathing. He realized that the volume of water displaced could be used to determine the crown’s density. Excited by his discovery, he reportedly jumped out of the bath and ran through the streets shouting “Eureka!”—“I have found it!” This phrase is still used today to express excitement over a discovery.
Archimedes proposed a method to compare the crown with a known weight of pure gold, which ultimately proved that the goldsmith had cheated the king. This incident led to the formulation of the Archimedes Principle, a fundamental law of physics still relevant in fluid mechanics today.
**Inventions and Achievements**
Throughout his life, King Hieron II often challenged Archimedes to create the impossible. One of his notable projects was the construction of a massive ship called The Syracusia, which was said to be one of the largest boats ever built in ancient times. Archimedes applied his understanding of buoyancy to ensure the ship could float despite its size.
Archimedes also invented the Law of the Lever and Balance, famously stating, “Give me a place to stand, and I will move the Earth.” He demonstrated this by lifting a ship using a lever system, showcasing the revolutionary nature of his simple machines.
His contributions to mathematics were profound. In his work “On the Measurement of the Circle,” he calculated the value of Pi and explored the volume and surface area of various shapes. Archimedes was one of the first to use mathematical proofs systematically, laying the groundwork for future scientific inquiry.
**The Roman Invasion of Syracuse**
In the 3rd century BC, the Mediterranean was divided between the Carthaginians and the Greeks, with Rome preparing to expand its territory. After the First Punic War, Sicily became a Roman territory. King Hieron II maintained peace with Rome until his death, after which Syracuse faced Roman invasion.
Despite being in his 70s, Archimedes created innovative war machines that defended Syracuse for two years. His inventions included the Archimedes Claw, which could lift and capsize Roman ships, and powerful catapults that devastated enemy forces. He was also credited with using mirrors to focus sunlight and ignite Roman ships.
However, by 212 BC, Syracuse could not withstand the siege any longer. The city eventually fell to the Romans, who recognized Archimedes’ genius and sought to protect him.
**Death and Legacy**
After the capture of Syracuse, a Roman soldier unknowingly interrupted Archimedes while he was working on mathematical drawings in the sand. Outraged, Archimedes reportedly exclaimed, “Do not disturb my circles!” before being killed. He was 75 years old.
Archimedes was buried in a tomb that honored his mathematical achievements, featuring a sphere and a cylinder, representing his work on their volume and surface area. Over time, his works were copied and preserved, although many original texts were lost.
In 1906, a manuscript known as the Archimedes Palimpsest was discovered, containing some of his lost works. A dedicated team restored the text, making it available for public access.
Archimedes’ contributions to mathematics, science, and engineering have had a lasting impact on the world. His legacy continues to influence modern thought, and without his brilliance, the world would indeed be a very different place.
