Directions for Questions Analyse the following passage and provide appropriate answers. An example of a scientist who could measure without instruments is Enrico Fermi (1901-1954), a physicist who won the Nobel Prize in physics in 1938. He had a Well-developed knack for intuitive, even casual sounding measurements. One renowned example of his measurement skills was demonstrated at the first detonation of the atom bomb, the Trinity Test site, on July 16, 1945, where he was one of the atomic scientists observing from base camp. While final adjustments were being made to instruments used to measure the yield of the blast, Fermi was making confetti out of a page of notebook paper. As the wind from the initial blast wave began to blow through the camp, he slowly dribbled the confetti into the air, observing how far back it was scattered by the blast (taking the farthest scattered pieces as being the peak of the pressure wave), Fermi concluded that the yield must be greater than 10 kilotons. This would have been news, since other initial observers of the blast did not know that lower limit. After much analysis of the instrument readings, the final yield estimate was determined to be 18.6 kilotons. Like Eratosthenes7 Fermi was aware of a rule relating one simple observation-the scattering of confetti in the Wind To a quantity he wanted to measure. The value of quick estimates was something Fermi was familiar with throughout his career. He was famous for teaching his students skills at approximation of fanciful-sounding quantities that, at first glance, they might presume they knew nothing about. The best-known example of such a Fermi question was Fermi asking his students to estimate the number of piano tuners in Chicago, when no one knows the answer. His students science and engineering majors-would begin by saying that they could not possibly know anything about such a quantity. Of course, some solutions would be to simply do a count of every piano tuner perhaps by looking up advertisements, checking with a licensing agency of some sort, and so on. But Fermi was trying to teach his students how to solve problems where the ability to confirm the results would not be so easy. He wanted them to figure out that they knew something about the quantity in question. Suppose you apply the same logic as Fermi applied to confetti, which of the following statements would be the most appropriate?
  • a)
    You can calculate the minimum pressure inside the cooker by calculating the maximum distance travelled by any of its parts after it explodes.
  • b)
    You can calculate the average potency of a firecracker by calculating the distance covered by one of its bigger fragments.
  • c)
    You can easily find out the average policy of an earthquake by measuring the length of a crack it makes on the surface of the earth.
  • d)
    You can calculate the exact volume of water stored in a tank by measuring the distance covered by the stream of water coming out of the tap fixed on the lower corner of the tank.
  • e)
    All the above conclusions can be drawn.
Correct answer is option 'A'. Can you explain this answer?

How do you solve this application question? First you derive what Fermi did: Fermi’s method was used to calculate the minimum estimate for the yield of the blast. Which options talk in terms of the minimum of some value? Option 1 is only one that fulfils this criteria, the other options provide us average or exact values, and hence can be ruled out.
