FRANKLIN’S EXPERIMENT: How Much Is True
弗兰克林的实验：有多少是真的？
Benjamin Franklin’s famous experiment with lightning has introduced generations of children to science. , new research suggests that the story may be fiction instead of fact.
The well-known story is that the American Founding Father and scientist (fly) a kite during a storm in 1752. At that time, there was much interest in electricity. People wanted (know) if lightning was really (produce) by electricity or something else. Franklin was one of them. He (raise) the kite with a piece of string tied to it. A metal key was (attach) to the string. A flash of lightning hit the kite, and electricity was conducted through the string to the key. Franklin then touched the key with his finger and got an electric shock. This, he said, proved that lightning was a form of electricity.
For many years, schools have taught the story of Franklin’s lightning experiment. More than one generation of schoolchildren has been amazed by his bravery and his (science)approach to ( look) for the truth. Franklin, along with many other scientists, has inspired us and taught us that scientific experiments are important in order to establish the truth and to contribute towards later scientific discoveries and inventions.
However, neither the story the details of the experiment are (entire)true. Although it has been proved that Franklin’s experiment took place, more than one scientist has questioned what really happened. The detail about the string and the key is true. But scientists all agree that Franklin had actually touched the key, he would certainly have died from the electric shock.
Scientists often question accepted ideas because they want to establish the facts. Some have even questioned the story about the apple that fell on Newton’s head and led him to come up his theory of gravity. fact, more than one account suggests that while Newton was certainly inspired by a falling apple, there is no proof that it hit him on the head.
(admitted), fiction is often more interesting than the truth. People have been more inspired by Franklin’s spirit of scientific exploration than by the facts themselves. But in science, facts should be proved by experiments and research, and we should not always believe everything we read or hear—even it is a great story.
