A book that finally demystifies Newton’s experiments in alchemy When Isaac Newton’s alchemical papers surfaced at a Sotheby’s auction in 1936, the quantity and seeming incoherence of the manuscripts were shocking. No longer the exemplar of Enlightenment rationality, the legendary physicist suddenly became “the last of the magicians.” Newton the Alchemist unlocks the secrets of Newton’s alchemical quest, providing a radically new understanding of the uncommon genius who probed nature at its deepest levels in pursuit of empirical knowledge. In this evocative and superbly written book, William Newman blends in-depth analysis of newly available texts with laboratory replications of Newton’s actual experiments in alchemy. He does not justify Newton’s alchemical research as part of a religious search for God in the physical world, nor does he argue that Newton studied alchemy to learn about gravitational attraction. Newman traces the evolution of Newton’s alchemical ideas and practices over a span of more than three decades, showing how they proved fruitful in diverse scientific fields. A precise experimenter in the realm of “chymistry,” Newton put the riddles of alchemy to the test in his lab. He also used ideas drawn from the alchemical texts to great effect in his optical experimentation. In his hands, alchemy was a tool for attaining the material benefits associated with the philosopher’s stone and an instrument for acquiring scientific knowledge of the most sophisticated kind. Newton the Alchemist provides rare insights into a man who was neither Enlightenment rationalist nor irrational magus, but rather an alchemist who sought through experiment and empiricism to alter nature at its very heart.

Unknown to all but a few, Newton was a practicing alchemist who dabbled with the occult, a tortured, obsessive character who searched for an understanding of the universe by whatever means possible. Sympathetic yet balanced, Michael White's Isaac Newton offers a revelatory picture of Newton as a genius who stood at the point in history where magic ended and science began.

Over the last forty years Professor Hall has been a major contributor to the 'new view' of Newton now generally accepted. Essentially this has derived from the bringing to light and examination of Newton's vast, but long neglected legacy of manuscripts, and the first studies in this volume illustrate the wealth of information these provide on the earliest phases of his great discoveries in mathematics and science. In particular, they confirm the intensity and originality of Newton's investigations before and through the 'anni mirabiles' of 1665-66. Further papers then deal with his relations with contemporaries such as Hooke, Leibniz and Huyghens, again making extensive use of unpublished manuscript material, and with the developing influence of his work. Durant les quarante dernières années, le professeur Hall a été l'un des plus importants contributeurs à la nouvelle appréciation de l'oeuvre de Newton, qui est de nos jours la plus généralement acceptée. Ceci provient essentiellement de l'examen du vaste héritage de manuscrits laissés par Newton et très longtemps négligé; les premières études de ce volume illustrent la richesse d'informations contenues dans ceux-ci quant aux toutes premières phases de ses grandes découvertes dans le domaine des mathématiques et de le science. Ils confirment en particulier l'intensité et l'originalité des recherches de Newton avant et pendant les anni mirabiles de 1665-66. S'ajoutent à ceci plusieurs études, oÃ1 il est à nouveau fait grand usage de manuscrits inédits, traitant des rapports qu'il entretenait avec ses contemporains tels, Hooke, Leibniz et Huyghens, ainsi que de l'influence progressive de ses travaux.

A distinguished set of scientist-historians describe the persona, the times, and the achievements of seventeen notable scientists from Aristotle to Watson and Crick. Porter's aim has been to trace the precepts that underlie Western science concepts of order and unity that might explain the rise to world dominance of this form of reasoning.
