James Clerk Maxwell était un physicien mathématicien écossais dont le travail a fondamentalement modifié notre compréhension de l'électricité, du magnétisme et de l'optique. Il a formulé les équations clés décrivant ces phénomènes comme des manifestations d'un unique champ électromagnétique. Ses découvertes ont démontré que les champs électriques et magnétiques se propagent dans l'espace sous forme d'ondes à la vitesse de la lumière, unifiant ainsi la lumière aux phénomènes électriques et prédisant l'existence des ondes radio. Le travail pionnier de Maxwell a jeté les bases de la physique moderne, y compris la relativité restreinte et la mécanique quantique, et son influence sur la physique du XXe siècle est comparée à celle de Newton et Einstein.
Volume 1 of an important foundation work of modern physics describes electrostatic phenomena and develops a mathematical theory of electricity. Topics include electrical work and energy in a system of conductors, mechanical action between two electrical systems, spherical harmonics, electric current, conduction and resistance, electrolysis, and other subjects. 1891 edition.
Chloe's quest to escape the Oracle's prophecy leads her to a magus with a secret: the eldren are not the only race to use magic in warfare. An ancient power is rediscovered, race to use magic in warfare. An ancient power is rediscovered, and a forgotten people will return. Meanwhile, cursed by his and a forgotten people will return. Meanwhile, cursed by his birth, Dion tries to forge a new life at sea, away from both the eldren and his former life in Xanthos. But the one thing he can't leave behind is his heritage.

Excerpt from A Treatise on Electricity and Magnetism, Vol. 1 In describing the phenomena, I shall select those which most clearly illustrate the fundamental ideas of the theory, omitting others, or reserving them till the reader is more advanced. The most important aspect of any phenomenon from a mathematical point of view is that of a measurable quantity. I shall therefore consider electrical pheno mena chiefly with a view to their measurement, de scribing the methods of measurement, and defining the standards on which they depend. In the application of mathematics to the calculation of electrical quantities, I shall endeavour in the first place to deduce the most general conclusions from the data at our disposal, and in the next place to apply the results to the simplest cases that can be chosen. I shall avoid, as much as I can, those questions which, though they have elicited the skill of mathematicians, have not enlarged our knowledge of science.

The epic conclusion to James Maxwell's gripping fantasy series. The world is facing a war to end all wars, a confrontation that will destroy everything Dion and Chloe hold dear. With Palemon's dragon army growing in number, time is running out... Dion is doing everything in his power to prepare his kingdom, but he knows it will not be enough. Although he needs Chloe's help, recent tragedy makes him terrified for her safety. Magic is dangerous. Only Palemon is too arrogant to see it. As chaos engulfs the land and Palemon risks civilization itself, Dion and Chloe must unite people of all nations to have any chance of survival.
"The Lord of the Night is coming. The future of civilization is at stake. Miro, High Lord of Altura, is in the Imperial capital to prepare the Empire for the onslaught. He knows his homeland lies directly in the enemy's path but struggles to form the alliances he needs. As the high lords bicker, Ella seeks the help of the newly crowned emperor, Killian. But, amid the growing tensions, their responsibilities drive them apart and, as emperor, Killian can't be seen to favor Ella's homeland. Against a backdrop of old hurts, guilty secrets, and shaky new allegiances, people of all nations and abilities must learn to trust one another again, and form a united front against a powerful enemy intent on destroying them once and for all"--P. [4] of cover.
Two years have passed since the war, yet without essence the Empire's economy has collapsed. Trade is at a standstill, famine sets in, and, with no food and no essence, the people begin to riot. In the midst of the growing unrest, Miro struggles to balance his life with Amber against his resolve to keep threats to the Empire at bay. His sister, Ella, helps to build the machinery the Empire desperately needs, but she longs to find Killian and believes his powers will be needed in the conflict to come. News of a wedding brings a much-needed ray of hope to the weary people. But as citizens and leaders gather from afar for the festivities, an evil threat shatters the fragile peace: one of the Evermen has returned. And he will not rest until he has completely destroyed the humans he despises. This is the third book in the epic Evermen Saga.
Taimin and Selena must discover the truth about their world—before it’s too late.In a world of secrets, Taimin and Selena are desperate for answers. They need to discover the truth about their origins and the firewall that borders the wasteland. If they don’t find the hidden path they seek, the citizens of Zorn will die.As they make the perilous journey to the distant firewall, Taimin and Selena are joined by three companions: a young healer, a weapons trader, and an old rover. Together the five are in constant danger, unable to rely on Selena’s powers as she has lost the ability to farcast—and she doesn’t know how to get it back.Now Taimin finds himself hunted by a new enemy—a strange creature on a bloodthirsty quest of his own. Taimin and Selena get ever closer to the answers that are essential to their survival. But will they learn the truth in time to save themselves?
The second book in the epic Evermen Saga. With the fate of their homeland still in jeopardy, siblings Ella and Miro must face the Primate's evil as he discovers a new technique: a way to extract essence from human blood. The Primate has been temporarily defeated, but his home was once inhabited by the Evermen, and their ancient secrets still remain there. As the mysterious Evrin sets out to destroy everything he can, the Primate stumbles upon an ancient book that tells of a hidden relic with unfathomable power--and he will stop at nothing to find it. Realizing the solution to defeating the Primate and saving the Empire is tied to the hidden relic, Ella, Miro, Killian, and the desert prince Ilathor must race to reach the relic before the Primate...or suffer disastrous consequences.
"The discovery of a strange and superior warship sends Dion, youngest son of the king of Xanthos, and Chloe, a Phalesian princess, on a journey across the sea, where they are confronted by a kingdom far more powerful than they could ever have imagined. But they also find a place in turmoil, for the ruthless sun king, Solon, is dying. In order to gain entrance to heaven, Solon is building a tomb—a pyramid clad in gold—and has scoured his own empire for gold until there’s no more to be found. Now Solon’s gaze turns to Chloe’s homeland, Phalesia, and its famous sacred ark, made of solid gold. The legends say it must never be opened, but Solon has no fear of foreigners’ legends or even their armies. And he isn’t afraid of the eldren, an ancient race of shape-shifters, long ago driven into the Wilds. For when he gets the gold, Solon knows he will live forever" -- back cover.
