"This is one of the two premises of this paper, which I have named the equivalence principle…"
Blake did not find it hard to understand or accept that gravitational mass and inertial mass could be described as equal under an appropriate measure system. Some arcanists had done corresponding research and obtained accurate data. However, they all considered the equivalence of the two masses as a coincidence and did not study the deeper things behind the coincidence.
Listening to Lucien's brief introduction to the experiment and the data, Blake felt that his head was swelling. He simply took out a piece of paper and a quill, recording and calculating on the table where the magic radio was placed, as careful as a student who was attending the class of a master.
