The Lost Elements
In the mid-nineteenth century, chemists came to the conclusion that elements should be organized by their atomic weights. However, the atomic weights of various elements were calculated erroneously, and chemists also observed some anomalies in the properties of other elements. Over time, it became clear that the periodic table as currently comprised contained gaps, missing elements that had yet to be discovered. A rush to discover these missing pieces followed, and a seemingly endless amount of elemental discoveries were proclaimed and brought into laboratories. It wasn't until the discovery of the atomic number in 1913 that chemists were able to begin making sense of what did and what did not belong on the periodic table, but even then, the discovery of radioactivity convoluted the definition of an element further. Throughout its formation, the periodic table has seen false entries, good-faith errors, retractions, and dead ends; in fact, there have been more elemental discoveries" that have proven false than there are current elements on the table. The Lost Elements: The Shadow Side of Discovery collects the most notable of these instances, stretching from the nineteenth century to the present. The book tells the story of how scientists have come to understand elements, by discussing the failed theories and false discoveries that shaped the path of scientific progress. Chapters range from early chemists' stubborn refusal to disregard alchemy as legitimate practice, to the effects of the atomic number on discovery, to the switch in influence from chemists to physicists, as elements began to be artificially created in the twentieth century. Along the way, Fontani, Costa, and Orna introduce us to the key figures in the development of the periodic table as we know it. And we learn, in the end, that this development was shaped by errors and gaffs as much as by correct assumptions and scientific conclusions."
The Way of Tarot
Filmmaker Alejandro Jodorowsky’s insights into the Tarot as a spiritual path • Works with the original Marseille Tarot to reveal the roots of Western wisdom • Provides the key to the symbolic language of the Tarot’s “nomadic cathedral” • Transforms a simple divination tool into a vehicle for self-realization and healing Alejandro Jodorowsky’s profound study of the Tarot, which began in the early 1950s, reveals it to be far more than a simple divination device. The Tarot is first and foremost a powerful instrument of self-knowledge and a representation of the structure of the soul. The Way of Tarot shows that the entire deck is structured like a temple, or a mandala, which is both an image of the world and a representation of the divine. The authors use the sacred art of the original Marseille Tarot--created during a time of religious tolerance in the 11th century--to reconnect with the roots of the Tarot’s Western esoteric wisdom. They explain that the Tarot is a “nomadic cathedral” whose parts--the 78 cards or “arcana”--should always be viewed with an awareness of the whole structure. This understanding is essential to fully grasp the Tarot’s hermetic symbolism. The authors explore the secret associations behind the hierarchy of the cards and the correspondences between the suits and energies within human beings. Each description of the Major Arcana includes key word summaries, symbolic meanings, traditional interpretations, and a section where the card speaks for itself. Jodorowsky and Costa then take the art of reading the Tarot to a depth never before possible. Using their work with Tarology, a new psychological approach that uses the symbolism and optical language of the Tarot to create a mirror image of the personality, they offer a powerful tool for self-realization, creativity, and healing.
