CAN YOU GUESS THIS SCIENTIST??
Archimedes
(284BC-212BC)
Was a Greek mathematician, philosopher and inventor who wrote important works on geometry, arithmetic and mechanics.
BIOLOGY
Archimedes was born in Syracuse on the eastern coast of Sicily and educated in Alexandria in Egypt. He then returned to Syracuse, where he spent most of the rest of his life, devoting his time to research and experimentation in many fields.
Archimedes had many famous quotations, but the one which showed his interest in science, especially in maths is : “There are things which seem incredible to most men who have not studied mathematics.”


Do you want to be incredible?? If you don’t, let’s study mathematics as soon as possible, and as deeply as you can.
In mechanics he defined the principle of the lever and is credited with inventing the compound pulley and the hydraulic screw for raising water from a lower to higher level. He is most famous for discovering the law of hydrostatics, sometimes known as `Archimedes` principle`, stating that a body immersed in fluid loses weight equal to the weight of the amount of fluid it displaces. Archimedes is supposed to have made this discovery when stepping into his bath, causing him to exclaim `Eureka!`
"Give me a place to stand and I will move the earth"
But if we gave Archimedes a fulcrum, it would take him 1 000 000 000 000 000 000 000 seconds (or 30 000 000 000 000 years) to lift the Earth up about 1cm.
“Do not disturb my circles!”
“Soldier, stand away from my diagram.”

And, after saying this word, he was killed by the soldier, the stupid guy who never ever studied mathematics and known Archimedes.

He loved science till the time he dead.

His interest in science could pass everything, also the death.
