When the downtrodden animals of Manor Farm overthrow their master, Mr Jones, and take over the farm themselves, they imagine it is the beginning of a life of freedom and equality. But gradually a cunning, ruthless elite among them, masterminded by the pigs Napoleon and Snowball, starts to take control. Soon the other animals discover that they are not all as equal as they thought, and find themselves hopelessly ensnared as one form of tyranny is replaced with another. Orwell's chilling 'fairy story' is a timeless and devastating satire of idealism betrayed by power and corruption.

<p>Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born . . .<br/><br/>With lightness and magic, here Rovelli traces the ongoing adventure of his own cutting-edge research, of the uncertainty and joy of going where we've not yet been. Guiding us to the edge of theory and experiment, he invites us to go beyond, to experience the fever and the disquiet of science. Here is the extraordinary life of a white hole.</p>
