The title of the book is taken from 1907' s poem by Joseph Rudyard Kipling, a British novelist, poet and Nobel Prize in Literature winner: "Where is the 5,000? How about the 7,000? Why is it 100,000?"
This book was published in 1929, and was quickly translated and introduced to China in a short time, with many publishing units, which had a great influence on China's popular science creation. China's older generation of popular science writers and many popular science writers who grew up in 1950s benefited from Millin's works.

Millin was born in Ukraine. He loved reading, nature and scientific experiments since he was a child. When I was a child, I carefully observed and studied the life of ants and observed the sky and stars. All these laid the foundation for him to use literary techniques and poetic artistic conception to create popular science works in the future. 19 14 graduated from middle school and won the gold medal with honors.
From 1924, when he was still in college, he began to write essays on science and literature. 1925 graduated from Leningrad Institute of Technology. The Sleepless Sky, written on 1927, is his first weighty work, which was loved by readers as soon as it was published.
