Black holes are places in space and time where the laws of gravity, quantum physics and thermodynamics collide. Originally thought to be so intellectually troubling that they simply could not exist, it is only in the past few years that we have begun to glimpse a new synthesis; a deep connection between gravity and quantum information theory that describes a holographic universe in which space and time emerge from a network of quantum bits, and wormholes span the void.
Chemistry is not just about microscopic atoms doing inscrutable things; it is the process that makes flowers and galaxies. We rely on it for bread-baking, vegetable-growing, and producing the materials of daily life. In stunning images and illuminating text, this book captures chemistry as it unfolds. Using such techniques as microphotography, time-lapse photography, and infrared thermal imaging, The Beauty of Chemistry shows us how chemistry underpins the formation of snowflakes, the science of champagne, the colors of flowers, and other wonders of nature and technology. We see the marvelous configurations of chemical gardens; the amazing transformations of evaporation, distillation, and precipitation; heat made visible; and more.
When they had thus shared by treaty a city they had notyet conquered, they commenced their operations for thesiege. The Christian army left Jerusalem, and the Venetianfleet the port of Ptolemaïs, towards the beginning of spring.The historian of the kingdom of Jerusalem, William of Tyre,was for a long time archbishop of this celebrated commercialcity, and he pauses here to describe the ancient wonders ofhis metropolis. In his recital, at once religious and profane,he invokes by turns the evidence of Isaiah and Virgil; afterspeaking of King Hyram and the tomb of Origen, he doesnor disdain to celebrate the memory of Cadmus and thecountry of Dido. The good archbishop particularly vauntsthe industry and the commerce of Tyre, the fertility of itsterritory, its dyes, so celebrated in all antiquity; its sand,which changed itself into transparent vases, and its sugar-canes,which began to be sought for by all regions of theuniverse. The city of Tyre, in the time of Baldwin, was nolonger that sumptuous city, whose rich merchants, according106to Isaiah, were princes; but it was still considered as thebest-peopled and most commercial of the cities of Syria. Itstood upon a delightful shore, screened by mountains fromthe blasts of the north; it had two large moles, which, likelong arms, advanced into the sea, to inclose a port to whichstorm or tempest could find no access. The city of Tyre,which had stood out during more than seven months againstthe victorious Alexander, was defended on one side by astormy sea and steep rocks, and on the other by a triplewall, surmounted by high towers.
