"I am looking for a book
There is often help to find a book, maybe I will be lucky.
Fantastic and Soviet. I remember the beginning, page five. The scientist is alone at home, his wife is away. Irka, his wife, will bring a fish order from work. At home, it is hot and dull, he washes his dishes and thinks about a scientific problem. Mathematics or physics, models of something. He can’t stop, reflect, there’s an idea of spheres or bubbles, brilliant and potentially dangerous. Share the discovery with the neighbor, just have to tell someone. A neighbor (resigned major, "third calac" some) suddenly disappears in the morning, and a fellow servant comes to the scientist with the question of what he is now working on. I could not read further. I want to find. Unfortunately, Google did not help."

Strugatsky, A Billion Years Before the End of the World
A great thing!
