Tesla built an experimental station in Colorado Springs, Colorado in 1899, to experiment with high voltage, high frequency electricity and other phenomena. When the Colorado Springs Tesla Coil magnifying transmitter2 was energized, it created sparks 30 feet long. From the outside antenna, these sparks could be seen from a distance of ten miles. From this laboratory, Tesla generated and sent out wireless waves which mediated energy, without wires for miles. In Colorado Springs, where he stayed from May 1899 until 1900, Tesla made what he regarded as his most important discovery - terrestrial stationary waves. By this discovery he proved that the Earth could be used as a conductor and would be as responsive as a tuning fork to electrical vibrations of a certain frequency. He also lighted 200 lamps without wires from a distance of 25 miles and created man-made lightning. At one time he was certain he had received signals from another planet in his Colorado laboratory.

The old Waldorf Astoria was the residence of Nikola Tesla for many years. He lived there when he was at the height of financial and intellectual power. Tesla organized elaborate dinners, inviting famous people who later witnessed spectacular
electrical experiments in his laboratory. (9)
Tesla lectured to the scientific community on his inventions in America and before scientific organizations in both England and France in 1892. Tesla’s lectures and writings of the 1890s aroused wide admiration among contemporaries, popularized his inventions and inspired untold numbers of younger men to enter the new field of radio and electrical science. (10)
Nikola Tesla was one of the most celebrated personalities in the American press,
in this century. Tesla was the genius who ushered in the age of electrical power. Tesla
had a vivid imagination and an intuitive way of developing scientific hypotheses. He used his imagination to prove and apply his hypotheses. Here is how he explained his creative process: “Before I put a sketch on paper, the whole idea is worked out mentally. In my mind I change the construction, make improvements, and even operate the device. Without ever having drawn a sketch I can give the measurements of all parts to workmen, and when completed all these parts will fit, just as certainly as though I had made the actual drawings. It is immaterial to me whether I run my machine in my mind or test it in my shop. The inventions I have conceived in this way have always worked. In thirty years there has not been a single exception. My first electric motor, the vacuum wireless light, my turbine engine and many other devices have all been developed in exactly this way.” (11)
Tesla possessed a striking physical appearance over six feet tall with deep set eyes and a stately manner. To the contemporaries he was a man endowed with remarkable physical and mental freshness, ready to surprise the world with more and more inventions as he grew older. (12)
In 1915, a New York Times article announced that Tesla and Edison were to share the Nobel Prize for physics. Oddly, neither man received the prize, the reason being unclear. It was rumored that Tesla refused the prize because he would not share with Edison, and because Marconi had already received his. (13)
Tesla was clearly ahead of his time, a problem which would haunt his entire career. His inventions and patents for remote operation of robotic devices, for instance, were stunningly advanced but largely ignored at the time. The military inexplicably failed to understand the usefulness of remote-controlled attack vehicles and torpedoes until after Tesla's patents had expired. Even then, they began researching it over from scratch, rather than working with his established techniques. The end result was military technology nearly identical to Tesla's inventions, but developed literally decades later and at many times the cost. Tesla never made a dime off of the discovery of the radio-controlled automation that today is the basis of a multibillion dollar aerospace specialty. (14)

British inventor Charles Babbage is one of the great paradoxes of computing history. Although he is often credited with developing the first "general-purpose computer," he never actually built any examples of his design. His steam-powered Analytical Engine, as it was called, would seem extremely primitive to us today, but in
the 1830s, it was a groundbreaking design. (1)
Рис.7 Charles Babbage |
Babbage was born in Teignmouth, Devonshire (UK) into a middle-class banking family. He followed an educational path typical for his age and status. His father’s money allowed Charles to receive instruction from several schools and tutors during the course of elementary education.
Around age eight he was sent to a country school to recover from a life-threatening fever with the strict instruction to the master not to press too much knowledge upon him. Perhaps this great idleness and a well-stocked library in the academy in Middlesex prompted his love of mathematics. Here he began to show a passion for mathematics but a dislike for the classics. On leaving the academy, he continued to study at home, having an Oxford tutor to bring him up to university level. He had read extensively in Leibniz, Lagrange, Simpson and was seriously disappointed in the mathematical instruction available at Trinity College in Cambridge. In response, he, John Hershel, George Peacock and several other friends formed the Analytical Society to try to bring the modern continental mathematics to Cambridge. (2)
