Demons: A World Full of Science - Like a Candle in the Dark

"A World Full of Demons" is the last book by Carl Sagan, an astronomer, astrophysicist, and outstanding popularizer of science, published after his death. This book, dedicated to one of his favorite topics - the human mind and the fight against pseudoscientific nonsense - is a kind of summary of all his work. Myths about Atlantis and Lemuria, faces on Mars and meetings with aliens, magic and reincarnation, clairvoyance and the yeti, creationism and astrology - Sagan relentlessly debunks myths created by ignorance, fear, and greed. This book is a manifesto of skepticism, a textbook of common sense and the scientific method. A vivid, deeply personal text - not only a battle with pseudoscience but also an extraordinary picture of the formation of a scientific worldview, the greatest discoveries, and the advocates of science. For Sagan, science is pure joy, it is wonderful in itself. Take for example a few facts: all information about a person is contained in every cell of the body; quasars are so far away that their light began to travel towards Earth even before it formed; all humans are related and descend from the same ancestors who lived millions of years ago. Science opens up unprecedented opportunities, and humanity no longer needs to create idols for itself and allow others to manipulate it.
