Almost everyone invents, but they do not recognize that their idea is an invention. Most inventors do not get credit (荣誉)for their ideas. That was true in the past and

today. The reason is simple, most inventors lack(缺少)the other skills they need to let people know what they have created and why their inventions are good.

Many inventions have little or nothing to do with science. But an understanding of science is often needed to make your invention work. And it is also important to be able to make the invention at a price that people can afford. Science will help you make choices on the best way and materials to make your invention.

Understanding business is also important. Most inventors have to make and sell the invention themselves. Big established businesses are usually not interested in an invention until they see their customers buying from the inventor.

You may be able to invent without understanding reading, writing, math, history and science. But you may not profit from inventing without all of those skills. You need to be able to read well to learn new skills. All the good ideas in the world are useless if you do not have the writing skills to be able to tell other people how and why your invention is valuable. You often need math to figure out(计算出)how to make your invention and you always need math to figure out the cost to make and sell the invention. And you almost always need science to make the invention at the lowest cost.

Although bicycles are still an important means of transportation for many people now,more and more people are riding them,for exercise and fun. This is especially true in some developed countries where cars are a common part of common people’s life. However,two centuries ago, when bicycles were first invented,they were used only for transportation.

In the eighteenth century, people usually traveled by horse and wagon(四轮马车). Many people worked in cities, but they liked to    go    to the countryside for    weekends    and

holidays.   But not everybody could afford a horse   or   a wagon. So there was  a    special    need

for the invention of a cheap and convenient means of transportation.

Then in 1790, the first bicycle was made. People called it “the horse on wheels”. Compared with the bikes we ride today,it was an extremely simple one. In 1861,after many improvements were made,the bicycle became a real means of transportation. People liked bikes because they weren’t as expensive as horsed and didn’t need to be fed. Also, they could go just about anywhere and were easy to ride.
