Science class usually meets him for Archimedes’ Principle: when you put an object in a liquid, it seems to weigh less, and that “lost” weight equals the weight of the liquid the object has pushed aside. That is why a heavy ship can float — the water it pushes away weighs as much as the ship.

Science class usually meets him for Archimedes’ Principle自然課通常會透過『阿基米德原理』認識他: when you put an object in a liquid, it seems to weigh less當你把一個物體放進液體裡，它看起來會變輕, and that “lost” weight equals the weight of the liquid the object has pushed aside而這個『減少』的重量，剛好等於這個物體排開的液體的重量。That is why a heavy ship can float這就是為什麼很重的船能夠浮起來 — the water it pushes away weighs as much as the ship因為它排開的水，重量跟這艘船一樣重。

A well-loved story says he saw this in the bath, shouted that he had found it, and ran through the streets still wet. Though actually, the running-from-the-bath part is a tale people enjoy, not a proof.

A well-loved story says he saw this in the bath有個很受歡迎的故事說，他是在洗澡時發現這個道理的, shouted that he had found it大喊他找到答案了, and ran through the streets still wet然後全身溼淋淋地跑到街上。Though actually不過事實上, the running-from-the-bath part is a tale people enjoy, not a proof光著身子從浴缸跑出來這一段，只是大家愛講的故事，而不是史實。
