1660: Otto von Guericke (Germany) described and demonstrated a vacuum, and then invented a machine that produced static electricity.
-
Elictricity
1600: William Gilbert(England) first coined the term "electricity" from "elektron," the Greek word for amber. Gilbert wrote about the electrification of many substances. He was also the first person to use the terms electric force, magnetic pole, and electric attraction. -
Ben Franklin (U.S.) tied a key to a kite string during a thunderstorm, and proved that static electricity and lightning were the same thing.
-
Alessandro Volta (Italy) invented the first electric battery. The quot;volt quot; is named in his honor.
-
Elictricity
1826: Georg Ohm (Germany) defined the relationship between power, voltage, current and resistance in Ohms Law. -
Elictricity motor
1837: Thomas Davenport(U.S.) invented the electric motor, an invention that is used in most electrical appliances today. -
Elictricity
1860s: Mathematical theory of electromagnetic fields published. J.C. Maxwell (Scotland) created a new era of physics when he unified magnetism, electricity and light. Maxwell's four laws of electrodynamics ("Maxwell's Equations") eventually led to electric power, radios, and television. -
He used the windmill to charge batteries in the cellar of his home in Cleveland, Ohio.
1888: Nikola Tesla (U.S. immigrant from Austrian Empire) demonstrated the first polyphase alternating current (AC) electrical system. His AC system included everything needed for electricity production and use: generator, transformers, transmission system, motor (used in appliances) and lights. George Westinghouse, the head of Westinghouse Electric Company, bought the patent rights to the AC system. Charles Brush(U.S.) was the first to use a large windmill to generate electricity. -
Powerline
1895-1896: The Niagara Falls hydropower station opened. It originally provided electricity to the local area. One year later, when a new alternating current (AC) powerline was opened, electric power from Niagara Falls was sent to customers over 20 miles away in Buffalo, New York. -
Electronic devieses
1953: IBM's 701 EDPM was the first commercially successful general-purpose computer. -
Electronic
The first electronic desktop calculators were the Anita Mk VII and Mk 8 which used vacuum tube technology. -
The arcade game Pong was created by Nolan Bushnell.
-
Spacewar
1972 Steve Russell (U.S.) invented Spacewar! The first game intended for computer use. -
Thomas Edeson
1879: After many experiments, Thomas Edison (U.S.) invented an incandescent light bulb that could be used for about 40 hours without burning out. By 1880 his bulbs could be used for 1200 hours. Electric lights (Brush arc lamps) were first used for public street lighting in Cleveland, Ohio. California Electric Light Company, Inc. in San Fransicso was the first electric company to sell electricity to customers. The company used two small Brush generators to power 21 Brush arc light lamps. -
Phones Apple
1993: The first PDAs or Personal Digital Assistants are released by the Apple Corporation(U.S.). -
Bluetooth Technology
1998: Ericsson, IBM, Intel, and Nokia cooperated to develop Bluetooth technology that allows wireless communication between mobile phones, laptops, pcs, printers, digital cameras, and video gam consoles. -
Elictricity
The iPOD, a portable media player, was launched by the Apple Corporation.2004: With the full color range of the high power light emitting diodes (LEDs), more advanced architectural designs and stage and studio lighting were developed. Colored LEDs reduce power consumption.
