最早发现杠杆原理的是古希腊的阿基米德。有一次,他曾经对国王说:“假如另外有一个世界,我可以到那里去,用杠杆来移动地球。”阿基米德不仅发现了杠杆原理,还发现了浮力定律,发明了抽水机、投石机和聚光点火法等等。i The earliest discovered principle of leverage was Archimedes of ancient Greece. On one occasion, he once said to the king: “If there is another world, I can go there and use the lever to move the earth.” Archimedes not only discovered the principle of leverage, but also found the law of buoyancy, invented the pumping machine, throwing stone Machine and condenser ignition method and so on. i
