Archimedes was a famous Greek mathematician and scientist. He was born around 287 B. C. and he died in 212 B. C.

Archimedes was most known for one specific idea that he came up with. “Archimedess Principle(定律)”states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold of the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than the water, while the gold weighs more.

It is believed the Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know whether his crown(王冠)was pure gold or a mixture of gold and silver. The king, of course, didnt want to melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of his tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith(金匠)was found guilty(有罪的)of trying to cheat the king.

Most of the time, fishermen catch more fish than they need for their immediate use. The extra fish can be dried or smoked for a later meal.  First, however, the fish must be cleaned and salted.

Put the cleaned fish in a mixture of 300g of salt and one liter of water to remove all of the blood from the fish meat. Keep them there for about 30 minutes. Then remove all the fish and wash them in clean water. Now, put them in a mixture which should be strong enough so that the fish float to the top. Cover the container with a clean piece of wood. Hold the wood down with a heavy stone. Leave the fish there for about 6 hours. Then, remove them from the salt water and lay them on a clean place. Cover them with a clean piece of white cloth. Let them dry.

After cleaning the fish, put a few of them on the bottom of a wooden box or basket. Cover them with salt. Continue putting fish and salt in the container until it is full.
