Nguyen, Vietnam- Level 3


Well, he was the man who went outside naked shouting “Eureka!”. He was very famous because he explained how the lever works. He invented different gears. You may not know about all his discoveries and inventions.

He used bars to pull a boat from the land to the sea, he knew how to distinguish real from fake gold by its mass. He designed big weapons that destroyed boats. One of these weapons is the rock thrower that can throw rocks at a distance of about 200m!

He also made the anchor that pulls a boat down. He used a convex mirror to start fire on a boat and so people thought he was a witch.

He died because the Romans caught him and killed him while he was thinking how to draw a circle.
