"Newton?" The voice on the other end was puzzled, "What is Newton?"
"Newton was a person from the UK, a great physicist," Bai Yang explained, "The equation F=G·(m₁m₂/r²) that your teacher wrote on the draft paper is the law of universal gravitation. Here, F represents gravitational force, G is the gravitational constant, the two m's are the masses of celestial bodies, and r is the distance. It means that the force of gravity between two celestial bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them, OVER."
"Oh..."
The girl nodded with a half-understanding.
It doesn't matter if she doesn't understand what the monk chants as long as she keeps ringing the bell; nodding is enough.
