By Bernard Jaffe

This e-book is a vintage within the box of renowned technological know-how. commonplace interpreting because the Thirties, it really is one of many few historeis of chemistry to be aware of the lives of the good chemists. via those dramatic and human tales, it provides an authoritative and enjoyable account of the good discoveries and advances during this medical box. After many printings in 3 past versions, this booklet has been newly revised by means of the writer for this fourth edition.
Beginning with Trevisan and his lifelong look for the "philosopher's stone," the writer narrates the lives and discoveries of such towering figures as Paracelsus and his chemical remedy of illness; Priestley searching for phlogiston and discovering oxygen and carbon dioxide, Lavoisier making a new language of chemistry; Dalton and his Atomic concept; Avogadro and the belief of molecules, Mendeleeff arranging the desk of components lower than his Periodic legislation; the Curies separating radium; Thomson gaining knowledge of the electron; Moseley and his legislation of Atomic Numbers; Lawrence and the development of the cyclotron; and extra. the most dramatic bankruptcy within the e-book, the account of the improvement of nuclear fission, ends the tale of chemistry at its such a lot enormous fulfillment. a last bankruptcy discusses a number of the results of nuclear fission, the invention of nuclear fusion, and the new paintings with subatomic particles.
Bernard Jaffe is the writer of many different technological know-how books and several other technological know-how textbooks. Upon the unique book of this booklet, Mr. Jaffe obtained the Francis Bacon Award for the Humanizing of information. the yankee Chemical Society's heritage of Chemistry department venerated him in 1973 with its Dexter Award for "distinguished success within the historical past of chemistry."

The burning lens was so placed outside the belljar that the heat of the sun was concentrated upon the solid to be tested. With this apparatus, he endeavored, on Sunday, the first of August, 1774, "to extract air from mercurus calcmatus per $e" a red powder known to 38 CRUCIBLES: THE STORY OF CHEMISTRY Geber and made by heating mercury in the air. " But there was nothing startling about this. Others before him had obtained gases by heating solids. Scheele, the great Swedish apothecary chemist, had obtained the same results three years before by collecting "empyreal" air.

Surely Cavendish had proved that the gas came, not from the acids or water in the bottles, but from the metals themselves! But he must not announce this until he had investigated furtherit would not do to startle the world before he had made certain he was right. " Though extremely light he found it actually had weight. It was ponderable. He had nailed phlogiston itselfl Now, at the age of thirty-five, he published an account of this work on Factitious Airs in the Transactions of the Royal Society.

He was amazed at the result The gases suddenly disappeared and in their place was formed a beautiful white cloud which gradually settled out as a fine white powder. A great chemical change had taken place a deep-seated change. Two pungent gases had united to form an odorless white powderammonium chloride, now used as an electrolyte in the dry battery. Thus in the space of a few years Priestley, eager devotee of PRIESTLEY to made 37 number of significant discoveries. He began spend more and more time in his makeshift laboratory.
