没有时间的世界：爱因斯坦与哥德尔被遗忘的财富

[original title: "A World Without Time - The Forgotten Legacy of Goedel & Einstein" (Basic Books; 2004); author:  Palle Yourgrau); [Kurt Friedrich Gödel; English transcription as "Goedel")]
It is a widely known but little considered fact that Albert Einstein and
Kurt Gödel were best friends for the last decade and a half of
Einstein's life. The two walked home together from Princeton's Institute
for Advanced Study every day; they shared ideas about physics,
philosophy, politics, and the lost world of German science in which they
had grown up. By 1949, Gödel had produced a remarkable proof: In any universe described by the Theory of Relativity, time cannot exist.
Einstein endorsed this result-reluctantly, since it decisively
overthrew the classical world-view to which he was committed. But he
could find no way to refute it, and in the half-century since then,
neither has anyone else. Even more remarkable than this stunning
discovery, however, was what happened afterward: nothing. Cosmologists
and philosophers alike have proceeded with their work as if Gödel's
proof never existed - one of the greatest scandals of modern
intellectual history. A World Without Time is a sweeping,
ambitious book, and yet poignant and intimate. It tells the story of two
magnificent minds put on the shelf by the scientific fashions of their
day, and attempts to rescue from undeserved obscurity the brilliant work
they did together.
