NIKOLA TESLA (1856 ~ 1943) was a Serbian American inventor, electrical engineer, mechanical engi-neer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles.The investors showed little interest in Tesla's ideas for new types of motors and electrical transmission equipment and also seemed to think it was better to develop an electrical utility than invent new systems. They eventually forced Tesla out leaving him penniless. He even lost control of the patents he had generated since he had assigned them to the company in lieu of stock. He had to work at various electrical repair jobs and even as a ditch digger for $2 per day. Tesla considered the winter of 1886/1887 as a time of "terrible headaches and bitter tears." During this time, he questioned the value of his education. Chapter 1 My Early Life: The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs. This is the difficult task of the inventor who is often misunderstood and unrewarded. But he finds ample compensation in the pleasing exercises of his powers and in the knowledge of being one of that exceptionally privileged class without whom the race would have long ago perished in the bitter struggle against pitiless elements.Speaking for myself, I have already had more than my full measure of this exquisite enjoyment, so much that for many years my life was little short of continuous rapture. I am credited with being one of the hardest workers and perhaps I am, if thought is the equivalent of labor, for I have devoted to it almost all of my waking hours. But if work is interpreted to be a definite performance in a specified time according to a rigid rule, then I may be the worst of idlers. Every effort under compulsion demands a sacrifice of life-energy. I never paid such a price. On the contrary, I have thrived on my thoughts.In attempting to give a connected and faithful account of my activities in this series of articles which will be presented with the assistance of the Editors of the Electrical Experimenter and are chiefly addressed to our young men readers, I must dwell, however reluctantly, on the impressions of my youth and the circumstances and events which have been instrumental in determining my career. Our first endeavors are purely instinctive, promptings of an imagination vivid and undisciplined. As we grow older reason asserts itself and we become more and more sys-tematic and designing. But those early impulses, although not immediately productive, are of the greatest moment and may shape our very destinies. Indeed, I feel now that had I understood and cultivated instead of suppressing them, I would have added substantial value to my bequest to the world. But not until I had attained manhood did I realize that I was an inventor..

Mér? László korábbi nagy siker? k?nyvei komoly szellemi kalandot jelent?, gondolkodásra késztet?, ugyanakkor szórakoztató olvasmánynak bizonyultak. A Mindenki másképp egyforma 1999-ben elnyerte az ??v tudományos k?nyve Németországban” díjak egyikét. Mér? László új k?nyve a szerz? r?videbb, de nem kevésbé elmélyült, elgondolkodtató és szórakoztató írásait tartalmazza. Ezek t?bbsége a Magyar Narancs Egotrip rovatában jelent meg, a k?nyv címe azonos a szerz? ottani sorozatcímével. Ebben a k?nyvben a szerz? a legt?bb írást alaposan átdolgozta. A lényeg nemigen változott, de a szigorú újságcikk-m?faj szorításából kiszabadulva némelyik írás hosszabb, némelyik r?videbb lett – ahogy a téma kívánta. ?s hogy mi ez a talányos cím? A magyarázatot keresse a k?tetben! ?Eredeti szakmám matematikus, majd a m?szaki tudományokból kandidáltam, kés?bb pszichológiából lettem habilitált doktor, nemrég pedig a gazdaságpszichológia professzorává neveztek ki. Emellett k?zel húsz éve vezetek egy játékszoftver-fejleszt? céget, amelynek egyik alapítója vagyok. Tudományos szakcikkek mellett írtam néhány k?nyvet a szélesebb olvasók?z?nség számára is, ezek t?bb idegen nyelven is megjelentek. Az utóbbi években megszerettem a tárca m?faját is – ennek termését mutatja be ez a k?nyv.” Mér? László

The publication of Darwin’s The Origin of Species in 1859 marked a dramatic turning point in scientific thought. The volume had taken Darwin more than twenty years to publish, in part because he envisioned the storm of controversy it was certain to unleash. Indeed, selling out its first edition on its first day, The Origin of Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance his theory of natural selection and his assertion that species were not created all at once by a divine hand but started with a few simple forms that mutated and adapted over time. Whether commenting on his own poor health, discussing his experiments to test instinct in bees, or relating a conversation about a South American burrowing rodent, Darwin’s monumental achievement is surprisingly personal and delightfully readable. Its profound ideas remain controversial even today, making it the most influential book in the natural sciences ever written—an important work not just to its time but to the history of humankind.

The Travels of Ibn Fudayl is a satirical tale written in the style of an academic who has translated a medieval manuscript. It comes complete with a foreword, introduction, bibliography and copious footnotes that poke fun at the pretentious world of academia, whilst chronicling Ibn Fudayl's experiences in Al-Andalus. In particular, how his search for wisdom leads him to meet the philosopher Al-Homsi, the world's most ignorant man. It is their friendship and love for worthless knowledge that enables Ibn Fudayl to reach the upper echelons of Andalusian society.
