Carl Sagan muses on the current state of scientific thought, which offers him marvelous opportunities to entertain us with his own childhood experiences, the newspaper morgues, UFO stories, and the assorted flotsam and jetsam of pseudoscience. Along the way he debunks alien abduction, faith-healing, and channeling; refutes the arguments that science destroys spirituality, and provides a "baloney detection kit" for thinking through political, social, religious, and other issues.

The Science of Kabbalah (Pticha)

The Science of Kabbalah (Pticha) is the first in a series of texts that Rav Michael Laitman, Kabbalist and scientist, designed to introduce readers to the special language and terminology of the Kabbalah. Here, Rav Laitman reveals authentic Kabbalah in a manner that is both rational and mature. Readers are gradually led to an understanding of the logical design of the Universe and the life whose home it is.
The Science of Kabbalah, a revolutionary work that is unmatched in its clarity, depth, and appeal to the intellect, will enable readers to approach the more technical works of Baal HaSulam (Rabbi Yehuda Ashlag), such as Talmud Eser Sefirot and Zohar.
Although scientists and philosophers will delight in its illumination, laymen will also enjoy the satisfying answers to the riddles of life that only authentic Kabbalah provides. Now, travel through the pages and prepare for an astonishing journey into the 'Upper Worlds'.
