阅读材料，回答题：Fermi Problem
On a Monday morning in July, the world's first atom bomb exploded in New Mexico desert.Forty seconds later, the shock waves reached the base camp where the Italian-American physicistEnrico Fermi and his team stood. After a mental calculation, Fermi announced to his team thatthe bomb's energy had equated 10,000 tons of TNT. The bomb team was impressed, but not sur-prised. Fermi's genius was known throughout the scientific world. In 1938 he had won a NobelPrize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear
age. Since Fermi's death in 1954, no physicist has been at once a master experimentalist( 实验室) and a leading theoretician(理论学家).
Like all virtuosos( 大师), Fermi had a distinctive style. He preferred the most direct routeto an answer. He was very good at dividing difficult problems into small, manageable bits talentwe all can use in our daily lives.
To develop this talent in his students, Fermi would suggest a type of question now known asa Fermi problem. Upon first hearing one of these, you haven't the remotest notion of the answer,and you feel certain that too little information had been given to solve it. Yet when the problem isbroken into sub-problems, each answerable without the help of experts or books, you can comeclose to the exact solution.
Suppose you want to determine earth's circumference without looking it up. Everyone knowsthat New York and Los Angeles are about 3,000 miles apart and that the time difference betweenthem is three hours. Three hours is one-eighth of a day, and a day is the time it takes the planetto complete one rotation(旋转) , so its circumference must be eight times 3,000 or 24,000 mi-les. This answer differs from the true value, 24,902.45 miles, by less than four percent.
Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewardsof making independent discoveries and inventions. It doesn't matter whether the discovery is asimportant as determining the power of an atom or as small as measuring the distance between NewYork and Los Angeles. Looking up the answer, or letting someone else find it, deprives you of thepleasure and pride that accompany creativity, and deprives you of an experience that builds up
self-confidence. Thus, approaching personal dilemmas as Fermi problems can become a habit thatenriches your life.
Fermi's team was impressed by Fermi's announcement in the base camp because he couldeven work out the power of the atom bomb in his mind. A．Right
B．Wrong
