The Ancient Hidden Art of Alchemie, Containing the right and perfect means To make the Philosophers Stone Aurum Potabile, with other Excellent Experiments, Divided lnto Twelve Gates. Sir George Ripley (c. 1415-1490) was an English Augustinian canon, author, and alchemist.

"To All Ingeniously Elaborate Students, In the most Divine Mysteries of Hermetique Learning." Or so British politician and Freemason ELIAS ASHMOLE (1617-1692) dedicated this curious artifact of the esoteric and spiritual philosophy of alchemy. An avid collector of antiquaries and other oddities (they were, upon his death, bequeathed to Oxford University, which used them to found the Ashmolean Museum), Ashmole counted among his treasures volumes of metaphysical poems available only in private, and fiercely guarded, manuscripts. In 1652, though, he collected many of these writings in this hefty tome, annotated with his own comments. Included are: . "The Ordinall of Alchimy" by Thomas Norton . "The Compound of Alchymie" by Sir George Ripley . "Liber Patris Sapientiae" . "The Tale of the Chanons Yeoman" by Geoffry Chaucer . "The Worke of John Dastin" . "The Hunting of the Greene Lyon" by the Viccar of Malden . "Bloomsfields Blossoms: Or, The Campe of Philosophy" . "Sir Ed Kelley Concerning the Philosopher's Stone" . and much more. Once a resource for such natural philosophers as Isaac Newton, the Theatrum Chemicum Brittannicum remains an astonishing album of arcania.

Alchemy, the Noble Art, conjures up scenes of mysterious, dimly lit laboratories populated with bearded old men stirring cauldrons. Though the history of alchemy is intricately linked to the history of chemistry, alchemy has nonetheless often been dismissed as the realm of myth and magic, or fraud and pseudoscience. And while its themes and ideas persist in some expected and unexpected places, from the Philosopher's (or Sorcerer's) Stone of Harry Potter to the self-help mantra of transformation, there has not been a serious, accessible, and up-to-date look at the complete history and influence of alchemy until now.

From the New York Times bestselling author of The Zookeeper's Wife, an ambitious and enlightening work that combines an artist's eye with a scientist's erudition to illuminate, as never before, the magic and mysteries of the human mind. Long treasured by literary readers for her uncommon ability to bridge the gap between art and science, celebrated scholar-artist Diane Ackerman returns with the book she was born to write. Her dazzling new work, An Alchemy of Mind, offers an unprecedented exploration and celebration of the mental fantasia in which we spend our days—and does for the human mind what the bestselling A Natural History of the Senses did for the physical senses. Bringing a valuable female perspective to the topic, Diane Ackerman discusses the science of the brain as only she can: with gorgeous, immediate language and imagery that paint an unusually lucid and vibrant picture for the reader. And in addition to explaining memory, thought, emotion, dreams, and language acquisition, she reports on the latest discoveries in neuroscience and addresses controversial subjects like the effects of trauma and male versus female brains. In prose that is not simply accessible but also beautiful and electric, Ackerman distills the hard, objective truths of science in order to yield vivid, heavily anecdotal explanations about a range of existential questions regarding consciousness, human thought, memory, and the nature of identity.

The best way to understand chemical bonding may be to take a view appropriate to each individual system, a view which may be quite different for various systems. Sometimes two very different views are appropriate for the same system, and then the combination may even give the parameters needed to estimate the bonding energy by hand. Density Functional Theory, on the other hand, generally tries to take one view as applicable to all systems, and proceeds computationally.In contrast to the author's two previous well-known textbooks, Electronic Structure and the Properties of Solids (1989) and Elementary Electronic Structure (1999), in this book he tries to distill the essence of the representation of electronic structure in a much briefer description. It is shortened by focusing primarily on the bonding energies, the energy gained in assembling atoms as a molecule or a solid, or as a solid with a surface. A central point is that the same description of the electronic structure which gives this cohesion, can also be used to understand all of the other properties, though those other properties are not emphasized here. The effort is characterized by the title, which combines the modern word ?theory? with the ancient effort of ?alchemy? to make sense of the material world.
