Electricity is a concept that was discovered in part by many experts and scientists adding to its development throughout history. In fact, electricity is actually a force of energy that occurs in nature; thus, electricity was not invented, but rather discovered.Know More
Although they didn't realize it, in 600BC the Greeks discovered static electricity by rubbing fur on amber, which is a fossilized tree resin, and observing the attraction created between the two materials. In the 1930s, archaeologists discovered artifacts believed to be the attempts at making a battery. By the 17th century, there were already several electrical inventions, including the early form of the electrostatic generator. In 1752, Benjamin Franklin proved that lightning bolts and little electric sparks were virtually the same things.
Following Ben Franklin, in 1800, an Italian physicist named Alessandro Volta discovered that certain chemical reactions could produce electricity. He created a primitive electric battery capable of producing a steady flow of electricity. Having created the voltaic pile, Volta was the first person able to create a steady flow of electrical charge. When Michael Faraday created the electric dynamo, he opened the door for American inventor Thomas Edison and British scientist Joseph Swan, who each invented the incandescent filament light bulb around 1878 in their respective countries.Learn more about Inventions
Two Greek mathematicians pioneered research to navigate and map the Earth. Eratosthenes of Cyrene, chief librarian at the Ancient Library of Alexandria, calculated the circumference of the Earth in the third century B.C. In the second century B.C., Hipparchus of Nicea first used mathematics to calculate latitude and longitude, invented the first astrolabe to observe stars and measure latitude, and observed lunar eclipses to propose longitudes for specific cities.Full Answer >
Penicillin was discovered by bacteriologist Sir Alexander Fleming in 1928. The accidental discovery occurred when he observed several mold spores had fallen on and destroyed bacteria in an open laboratory dish.Full Answer >
Electricity is the flow of electrons through a conductor. Electricity is based on the principle that all matter has negatively and positively charged particles within its atoms.Full Answer >
Electricity is the flow of electrons through a conductor. Materials that conduct electricity easily have a weak hold on their outermost electrons, allowing them to move easily from one atom to another. When an electron moves to an adjacent atom, it displaces another electron, and this flow is electric current.Full Answer >
