File Name: nikola tesla on light and other high frequency phenomena .zip
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in Tesla used these circuits to conduct innovative experiments in electrical lighting , phosphorescence , X-ray generation , high frequency alternating current phenomena, electrotherapy , and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the s,       and in medical equipment such as electrotherapy and violet ray devices.

Jump to navigation. Born in a rural village in Croatia, Nikola Tesla would bring his brilliant scientific mind to America in to work with Thomas Edison. It was George Westinghouse, however, who fully recognized Tesla's brilliance and initiated a partnership with him. During that temporary partnership with Westinghouse and for many years that followed, Tesla generated amazing new advances in electrical engineering and earned patents by the dozen. Nikola Tesla was born on July 9, , in Smiljan, a village in rural Croatia, then part of the Austro-Hungarian empire. He was the son of a Serbian Orthodox priest who was a notable preacher, and a clever and inventive, though uneducated, mother.
I cannot find words to express how deeply I feel the honor of addressing some of the foremost thinkers of the present time, and so many able scientific men, engineers and electricians, of the country greatest in scientific achievements. The results which I have the honor to present before such a gathering I cannot call my own. There are among you not a few who can lay better claim than myself on any feature of merit which this work may contain. I need not mention many names which are world-known -- names of those among you who are recognized as the leaders in this enchanting science; but one, at least, I must mention -- a name which could not bc omitted in a demonstration of this kind. It is a name associated with the most beautiful invention ever made: it is Crookes! When I was at college, a good time ago; I read, in a translation for then I was not familiar with you magnificent language , the description of his experiments on radiant matter.
Nikola Tesla 10 July - 7 January was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current AC electrical supply system. Tesla started working in the telephony and electrical fields before emigrating to the United States in to work for Thomas Edison. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla as a consultant to help develop an alternating current system. Tesla is also known for his high-voltage, high-frequency power experiments in New York and Colorado Springs which included patented devices and theoretical work used in the invention of radio communication, for his X-ray experiments, and for his ill-fated attempt at intercontinental wireless transmission in his unfinished Wardenclyffe Tower project. Tesla's achievements and his abilities as a showman demonstrating his seemingly miraculous inventions made him world-famous.
WHEN we look at the world around us, on Nature, we are impressed with its beauty and grandeur. Each thing we perceive, though it may be vanishingly small, is in itself a world, that is, like the whole of the visible universe, matter and force governed by law,-a world, the contemplation of which fills us with feel- ings of wonder and irresistibly urges ns to ceaseless thought and inquiry. But in all this vast world, of all objects our senses reveal to us, the most marvellous, the most appealing to our imagina- tion.
В АНБ было только одно помещение, еще более засекреченное, чем шифровалка, и Сьюзан поняла, что сейчас она окажется в святая святых агентства. ГЛАВА 109 Командный центр главного банка данных АНБ более всего напоминал Центр управления полетами НАСА в миниатюре. Десяток компьютерных терминалов располагались напротив видеоэкрана, занимавшего всю дальнюю стену площадью девять на двенадцать метров. На экране стремительно сменяли друг друга цифры и диаграммы, как будто кто-то скользил рукой по клавишам управления. Несколько операторов очумело перебегали от одного терминала к другому, волоча за собой распечатки и отдавая какие-то распоряжения.
После многочасовых поисков ее обнаружил младший лаборант. То была моль, севшая на одну из плат, в результате чего произошло короткое замыкание. Тогда-то виновников компьютерных сбоев и стали называть вирусами. У меня нет на это времени, - сказала себе Сьюзан. На поиски вируса может уйти несколько дней. Придется проверить тысячи строк программы, чтобы обнаружить крохотную ошибку, - это все равно что найти единственную опечатку в толстенной энциклопедии.
Значит, я не могу сойти. Парень захохотал. - Доедешь до конечной остановки, приятель. Через пять минут автобус, подпрыгивая, несся по темной сельской дороге. Беккер повернулся к панку.
