Lightning in a Bottle Trivia Quiz

The word electricity ultimately traces back to the Greek word elektron, meaning amber. Thales of Miletus lived c. 624 to c. 546 BC. Although he had no concept of electrons, his observation is the oldest known written account of an electrical effect, recorded more than 2,500 years before electric power grids existed.

William Gilbert (1544-1603) published "De Magnete" in 1600, distinguishing magnetism from the attractive effects produced by rubbed amber. As physician to Queen Elizabeth I, he was among the first scholars to study electrical and magnetic phenomena systematically through experimentation rather than relying on ancient authority.

His work earned him the title "father of electrical science."

Invented independently by experimenters in 1745-1746, the Leyden Jar was the first practical device for storing electrical energy. Public demonstrations became popular across Europe, with long chains of people receiving simultaneous shocks, demonstrating that electrical charge could be transmitted over a distance.

Alessandro Volta (1745-1827) built his battery from alternating discs of zinc and copper separated by cloth soaked in saltwater or a mild acid. Introduced in 1800, it provided the first continuous source of electric current rather than brief bursts of static electricity. The unit of electrical potential, the volt, was later named in his honour.

In 1820, Hans Christian Ørsted (1777-1851) noticed that a compass needle deflected whenever a nearby wire carried current. This accidental observation revealed the first clear link between electricity and magnetism. Within months, André-Marie Ampère (1775-1836) developed the mathematical principles describing the phenomenon, helping establish the field of electromagnetism.

Michael Faraday (1791-1867) discovered electromagnetic induction in 1831. His laboratory demonstration showed that magnetism could be converted directly into electricity, a breakthrough that transformed electricity from a scientific curiosity into a practical source of power.

Between 1861 and 1865, James Clerk Maxwell (1831-1879) showed mathematically that light is an electromagnetic wave. His work also predicted the existence of other electromagnetic waves. About two decades later, Heinrich Hertz (1857-1894) confirmed that prediction experimentally, laying the foundation for radio, television, radar, and modern wireless communication.

Thomas Edison (1847-1931) did not invent the first light bulb, but in 1879 he developed one that was practical, durable, and commercially viable. His carbon-filament bulbs could operate for hundreds of hours, making large-scale electric lighting a realistic alternative to gas lamps.

When the Pearl Street Station began operation in lower Manhattan on September 4, 1882, it supplied electricity to about 400 lamps serving 85 customers. Designed by Thomas Edison (1847-1931) and his company, it helped demonstrate that centralized power generation could reliably serve an entire neighbourhood, a model that became the blueprint for modern electric utility systems around the world.

The "War of the Currents" pitted Thomas Edison and his direct current (DC) system against the alternating current (AC) system promoted by Nikola Tesla (1856-1943) and George Westinghouse (1846-1914). The successful transmission of hydroelectric power from Niagara Falls in 1895 demonstrated AC's advantage over long distances. Within a few decades, AC had become the standard for electrical distribution across most of the world.
