The Mind's Sky

The bestselling author of Coming of Age in the Milky Way delivers fascinating essays on the human mind, the search for extraterrestrial (and thus nonhuman) intelligence, comet strikes as a source of species extinction, near-death experiences, apocalyptic prophecies, information theory, and the origin of laughter.
 
Praise for The Mind’s Sky
 
“It is a joy to read The Mind’s Sky. What a sense of humility in the face of mystery—the spirit of Ulysses, as Tennyson put it, determined ‘to strive, to seek, to find and not to yield’—and sense of poetry too!”—John Archibald Wheeler, physicist, Princeton University
 
“A few chapters into this wonderful book I suddenly realized that I was taking wider views of my own mind’s sky than I have enjoyed in a long time. Ferris illuminates (among other matters) the mysteries of laughter, nirvana, common sense, and Joe Montana. He makes us think big thoughts.”—Jonathan Weiner, author of The Next 100 Years and Planet Earth

“One of our best and most imaginative writers, Timothy Ferris has never been afraid to tackle big themes. The Mind’s Sky is a dazzling and provocative synthesis of inner and outer space. This book is sure to be as controversial as it is elegant.”—Dennis Overbye, author of Lonely Hearts of the Cosmos
