"Perfect Rigor" is a biography that depicts the life of the genius mathematician Perelman who solved the extremely difficult problem in mathematics, the Poincaré conjecture, and declined a million-dollar prize and a Nobel Prize-level honor. The book focuses on his personal life and the struggles of "the gifted" individual who was born and raised in the Soviet Union, with almost no mathematical descriptions.

In America, there are "private penitentiaries". "American Prison," written by an author who went undercover as a prison guard in one of them for research, is a non-fiction book that is filled with unbelievable descriptions. It depicts the historical background of how the world of madness, where inhumane acts prevail, came into being, as well as "private penitentiaries".

For those who felt that the title "Faster Than the Speed of Light" makes it a fallacious book, rest assured that this is actually a very legitimate work. Regardless of whether the varying speed of light theory (VSL theory) is correct, the book presents a challenging hypothesis that attempts to compensate for the flaws in the Big Bang theory with a different logic than cosmic inflation.

The movie "THE MOLE" is a film full of shocking footage that makes you wonder, "Is it really a documentary?" If the start of "A Danish ex-cook infiltrates North Korea on his own" is unintelligible, the development of a man with no intelligence or military experience revealing North Korea's secrets one after another is also too mysterious. It is a crazy work.

The world's top dictionary, the "Oxford English Dictionary," was created by a combination of a "self-taught man" without a degree and a "murderer." The unlikely meeting of these two "madmen" led to this great achievement, which teaches us about the reality that only "great accomplishment" can arise from "madness," as shown in the movie "The Professor and the Madman."

The "Math Girls" series by Yuki Hiroshi are math books for the general public that conveys the interesting aspects of mathematics while delving into quite advanced topics. The third volume's theme is "Gödel's incompleteness theorems." You will learn the theory of a young genius who shattered the ambition of a mathematician named Hilbert.
