At last, one of the world’s greatest works of science fiction is available - just as author Stanislaw Lem intended it. To mark the 50th anniversary of the publication of Solaris, Audible, in cooperation with the Lem Estate, has commissioned a brand-new translation - complete for the first time, and the first ever directly from the original Polish to English. Beautifully narrated by Alessandro Juliani ( Battlestar Galactica), Lem’s provocative novel comes alive for a new generation.

Scientists consider it the "hard problem" because it seems an impossible task to understand why we feel a subjective sense of self and how it arises in the brain. Venturing into the elementary physics of life, Solms has now arrived at an astonishing answer. In The Hidden Spring, he brings forward his discovery in accessible language and graspable analogies.

Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof.
