Until the End of Time
I started this book: Until the End of Time by Brian Greene last winter, and I just finished it now. There are so many deep thoughts there that I had to pause to absorb them, think about them, and digest them qualitatively.
Many parts of it are just amazing. It's kind of about physics, but a lot of philosophy, psychology, and sociology too. It basically tells you how the world works, what will happen next, and for millions of years to come.
It's even available in Russian. But I haven't seen the quality of the translation.
