“I am here to learn about the Law of Gravity,” said the student.
“You’ve come to a right place,” said the physicist.
“Is this the Temple of Gravity?” asked the student.
“No. This is the Jet Propulsion Laboratory,” said the physicist.
“I wish to learn about gravity. Where can I find a temple dedicated to the worship of gravity?” asked the student.
“There is no such thing,” said the physicist.
“Why not?” asked the student, “Is it not true that gravity created the Earth, the Sun, the Moon and the stars?”
“That is true…” said the physicist.
“And do you not obey the Law of Gravity here?”
“That is also true…” said the physicist, “But we obey the Law of Gravity everywhere.”
“You must be very devoted to the Law of Gravity,” said the student.
“Nonsense. We obey the Law of Gravity because we could not do otherwise,” said the physicist.
“What would happen if you disobeyed the Law of Gravity? Would you be sent to hell for blasphemy?” asked the student.
“No,” said the physicist.
“Then why do you obey it?” asked the student.
“I do not know,” said the physicist.
“Ah, I see that you do not understand the law of gravity,” said the student.
“That is technically true, but not relevant to this conversation. I believe that I understand the Law of Gravity better than you do,” said the physicist.
“But I have memorized $F=\frac{m_1m_2}{r^2}$,” said the student.
“And what is $r$?” asked the physicist.
“Radius,” said the student.
“And what is the radius?” asked the physicist.
“The bone that runs parallel to the ulna,” said the student.
