In physics,maths or other branches of natural science,you'll find many symbols,laws (定律；定理) and formulas (公式)． Such symbols,laws and formulas may be the scientists' language． With it a scientist can express his thoughts in a more exact and clear way．
Take chemistry for example． The scientist always uses symbols to represent elements (元素)． He uses the first letter of the name,capitalized,as the symbol． For example,the symbol for hydrogen (氢) is H,for oxygen (氧)is O,for nitrogen(氮) is N． With such symbols,he can form the formulas(分子式) of compounds (化合物)． As we know,the formula for water is H2O．
Sometimes,words in everyday use will change their meaning when scientists use them． One of the most interesting examples is the word “work．” In physics,“to do work” means to move something． If you push against something but do not move it,you have done no work． Here the word “work” is quite different in meaning from the same word in the saying “to do a good day's work．”
There are many ways for scientists to express their thoughts besides writing,such as by designs or through data (数据)．
The scientists'language is most important to scientific work． It is the ABC of science． Without it you cannot work at science,even a production plan cannot be carried out． And you cannot build a ship,a house,or a machine-tool (机床) if you do not know how to make design or how to read it．
