Archimedes

     

Archimedes is one of the greatest ancient Greek mathematician ever to walk the earth he was give birth to in Syracuse,suicy.🌍 He died at the age of 75 years old from the (287-212 BC )he spent most of his life in Greece and a bit of his life in Egypt he his known as a Greek mathematician,physicist,engineer inventor,and astronomer. He died during the seige of Syracuse also known as the second punic war which lasted for two long years by the Roman empire during that time it was Archimedes invention that keep away the  Invaders for so long like the Heat Ray which the Roman ships and catapults.

   After along siege the city was finally captured by the Roman under the rule of general Marcellus which instructed his men that Archimedes was a scientific asset. So that day the city was captured and a Roman solider when to meet him telling him that the general wants to see him and at that particular moment he was working on a mathematical diagram so he told the soilder that he should not disturb his circle causing the soilder to be annoyed therefore killing him. That caused the general to be enraged despite warning them.

   And Archimedes is also known for his great discoveries and invention 

For invention he created the

📍Archimedes screw : which is use for bringing water up from Wells in ancient times still in use in some undeveloped country.

📍 Antikythra mechanism: which is use in knowing the position of the star,sun and the calendar on the year.

  And some mathematical discoveries which are

📍 the laws of levers and pulleys, which allow us to move heavy objects using small forces.

📍Invented one of the most fundamental concepts of physics – the center of gravity.

📍He calculated the pi number to the most precise value known. His upper limit for pi was the fraction 22⁄7. This value was still in use in the late 20th century, until electronic calculators finally laid it to rest.

📍He discovered the mathematically formulas for the volume and surface area of a sphere.

📍he showed how exponents could be used to write bigger numbers than had ever been thought of before and

He even proved that to multiply numbers written as exponents, the exponents should be added together.

   Later in the future infuriated mathematicians who tried to replicate his discoveries 18 centuries later. they tried and failed to understand how Archimedes had achieved his results.  

📍And one of his best invention remembered through out history is the discovery of the Archimedes principal in which king Heiro  the second told him to determine whether is crown as been mixed with silver without damaging it so Archimedes went ahead trying all day to get it but he could not so he went to bathe while he wanted to bathe he noticed the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible,[24] so the submerged crown would displace an amount of water equal to its own volume. By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying "Eureka!" In Greek meaning "i have  found it" .The test was conducted successfully, proving that silver had indeed been mixed in

.

   Making him creating what we know as the Archimedes principle and the principle states that a body immersed in fluid loses weight equal to the weight of the amount of fluid it displaces.  

    His work was revolutionary that it still affects the world as we know it.
