I can't imagine modern civilization without electricity, and a couple of hundred years ago, science fiction writers who wrote about its use in everyday life, they hardly believed that it would become so widespread. But these days, electricity is literally everywhere, and its discovery and taming has given human civilization a major boost by providing it with energy.
Facts about Electricity
- The first mention of it as a phenomenon is over 4,000 years old. It was described in some ancient Egyptian chronicles.
- The first researcher who tried to experimentally get electricity was the ancient Greek philosopher and scientist Thales. He conducted his experiments about 2600 years ago. He was unsuccessful, but he guessed at the existence of static electricity.
- Near Baghdad, in the 1930s, an amazing artifact called the “Baghdad battery” was found. Apparently, this vessel with a metal rod and alkali created a voltage of about 1 Volt. Scientists estimate it was made about 2,200 years ago.
- In the mythology of almost all peoples, there are deities capable of commanding electricity and throwing lightning.
- The material carriers of electricity are electrons. They were discovered in 1897 by Joseph Thomson.
- The electrical nature of lightning was not reliably established until the 18th century.
- Even today, about 1 billion people on Earth do not have access to electricity.
- The lightning rod was invented by Benjamin Franklin, the man whose portrait is on the $100 bill.
- Fireflies are amazing insects that generate real electricity.
- It is through electricity that impulses are transmitted in the nervous system.
- The platypus animals sense the faintest discharges of electricity that arises when the muscles are tensed. It is on them they orient themselves when they hunt for fish in dark bodies of water at night.
- The term “electricity” itself was coined by the scientist William Gilbert in 1600.
- The occurrence of electric voltage in the muscles of living creatures was proven in 1791 by Italian scientist Luigi Galvani.
- The most environmentally friendly electricity is produced in hydroelectric power plants and, oddly enough, nuclear power plants. But even solar and wind power plants are less environmentally friendly, since their production and operation require the use of materials that pollute the environment.
- Russian engineer Lodygin invented the incandescent lamp in parallel with Edison, but independent of him.
- The world’s first power generator was created by Michael Faraday in 1831.
- The most powerful natural sources of electricity are found in nature. For example, electric eels and stingrays can easily kill even a person with an electric shock.
- Water conducts electricity very well, but not the H2O molecules themselves, but the impurities in the water, mainly mineral salts.
- The famous scientist Lomonosov ran wires from the lightning conductor to his laboratory, and during thunderstorms he researched electricity.
- The world’s first commercial power plant started operating in 1882 in New York City, providing power to several neighborhoods.
- Of all the widely available materials, silver is the best conductor of electricity.
- Electrical voltage in lightning can reach 1 billion volts .
- The most famous scientist who ever studied electricity is being Nikola Tesla, who devoted his entire life to his work.
