The linked chapter is “The Frozen River,” and authoritative book listings show that “The Frozen River” is chapter 5 of Brian Greene’s The Fabric of the Cosmos: Space, Time, and the Texture of Reality, not a book called The Fabric of Reality. Google Books lists Brian Greene’s book title and table of contents, including “The Frozen River 127” among its chapters.

A separate authoritative listing shows that The Fabric of Reality is a different book entirely, written by David Deutsch, not Brian Greene. So the post’s recommendation appears to have conflated Brian Greene’s The Fabric of the Cosmos with David Deutsch’s The Fabric of Reality.

In other words, the recommendation should point to Brian Greene, The Fabric of the Cosmos, chapter 5, not Greene, The Fabric of Reality, chapter 5.
