Об авторе книги The Demon-Haunted World

Carl Edward Sagan (1934–1996) was a renowned astronomer, astrophysicist, and science communicator who authored The Demon-Haunted World: Science as a Candle in the Dark, a seminal work in popular science that champions scientific skepticism and critical thinking. A professor at Cornell University and director of its Laboratory for Planetary Studies, Sagan’s career combined rigorous academic research—including NASA collaborations on the Mariner and Voyager missions—with a gift for making complex concepts accessible. His expertise in planetary science and extraterrestrial life studies underpins the book’s exploration of combating pseudoscience through rational inquiry.

Sagan’s legacy includes bestselling titles like Cosmos (adapted into the iconic PBS series), Contact (a science fiction novel later filmed), and Pale Blue Dot, all celebrated for bridging science and public understanding.

A vocal advocate for space exploration and nuclear disarmament, he co-developed the "nuclear winter" hypothesis and designed interstellar messages like the Voyager Golden Record. The Demon-Haunted World remains a foundational text, translated into over 20 languages and continuously praised for its urgent defense of evidence-based reasoning in an era of misinformation.
