2. The stars are the outstanding performance of Hua, while the dust is the stain of Watson's life.

3. Star refers to China's "On Prime Numbers of Heaps", and Dust refers to a mistake in the book.

"A Dot on the Star" comes from a letter written by Chen Jingrun (then an ordinary middle school student) to China: I have read your book "On the Prime Number of Piling Base" and think it is well written. But after repeated accounting, I found that one problem was miscalculated, which is like casting a dust on the stars. I hope you can correct it.

Hua read the letter and opened the book. Another calculation, really wrong. He is full of praise; "That's great. His opinion is completely correct. He has a high talent. "

Hua read the letter at the mathematical research meeting and invited the young people who wrote it to attend the meeting. The young man was Chen Jingrun, and later he became a famous mathematician.

Extended data

The book "The Theory of Prime Numbers on Pile Foundations" is divided into twelve chapters. Except Siegel's prime number theorem about arithmetic progression has not been proved, the book is self-sufficient, that is, all theorem proofs are contained in the book.

The first six chapters are all the most important theorems in trigonometric sum estimation method, except the second chapter is an inequality about divisor function. These results are the basis and the most basic method of analytic number theory.
