Exercise 54
IELTS Reading: multiple choice
Read the following passage and answer the two questions below it.
Physicist Richard Feynman returned over and over to an idea that drove his
groundbreaking discoveries. His approach was documented by his Caltech colleague David
Goodstein in the book
Feynman’s Lost Lecture about physics classes Feynman taught in
the 1960s:
Once, I said to him, “Dick, explain to me, so that I can understand it, why spin one-half
particles obey Fermi-
Dirac statistics.” Sizing up his audience perfectly, Feynman said, “I’ll
prepare a freshman lecture on it.” But he came back a few days later to say, “I couldn’t do
it. I couldn’t reduce it to the freshman level. That means we don’t really understand it.”
Feynman didn’t mean all human knowledge must be distilled into an introductory college
course. His point was that we need to build our grasp of science and technology from the
ground up if we are to master it, not to mention reimagine how it works. Feynman was
famous as a student for redoing many of physics’ early experiments himself to build a
foundational understanding of the field. By mastering these first principles, Feynman often
saw things that others did not in quantum mechanics, computing, and nuclear physics,
earning him the Nobel Prize in 1965.
1. When asked to explain a difficult concept, physicist Richard Feynman
A immediately replied that he could not
B replied that he had already prepared a lecture on it
C said that he did not understand the concept either
D promised to give his answer in an introductory lesson
