参考解析
解析：答案的依据是第一段第三句话：“ After a mental calculation , Fermi announced to hiteam that the bomb's energy had equated 10,000 tons of TNT. The bomb team was impressed , but not surprised. ” Fermi在做了一番心算以后，得出了该原子弹具有相当于 10,000吨TNT的爆炸力。他的话给队员们留下了深刻的印象。很显然给队员们留下深刻印象是因为他能在脑海里算出原子弹的爆炸力。因此题干叙述正确。
文章第一段中提到：“ In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction… ” Fermi在1938年获诺贝尔奖，四年以后才成功地实现了核连锁反应。所以题干的说法是错误的。
答案的依据是第二段的第三句：“ He was very good at dividing difficult problems into small , manageable bits talent we all can use in our daily lives.”题干只不过是换了一种表达方式。
答案的依据是第三段的内容。第一句中的his talent指第二段提到的将难以解决的问题分解成几个容易处理的小问题。第三段对这种解决问题的方法又进一步作了描写。
第四段是为第二段和第三段的内容提供实际例子，即Fermi problem的实际运用，并不是Fermi在解决地球周长这个问题。由此可见，题干的说法是错误的。
最后段是全篇的结论，强调了Fermi问题的价值“Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions”。
文章根本没有提到他发明了一台能精确计量炸弹能量的仪器。
