Today, the comfort of our lives is provided fordue to the abundance of technical equipment and various household appliances, without which it is already difficult for us to manage. We perceive them on a subconscious level, without thinking about how they work, who was their inventor. A person by his nature always strives for more, he sets ambitious plans for himself, systematically overcoming all difficulties. There are plenty of examples of how people, forgetting about adversity, strove forward.
However, you should never forget your pastMoreover, there are enough examples that can be useful now. Then there were completely different tasks, seemingly more simple and elementary, but imagine if there were no ordinary light bulb, how would we live now? Probably, we would not have thought about modern technologies, flights into space and powerful computers, but still tried to establish our own life if we had forgotten who invented the light bulb.
We are accustomed to attribute inventions to specificpeople, although sometimes the result is the combined work of a large number of people, but, for example, who invented the incandescent bulb, which is now in every home?
Light in every home
It is necessary to understand that people could not live without light,therefore, by all means, they tried to invent something to illuminate their homes. In the most ancient times, bonfires, stoves and fireplaces were used, then candles were used. But the use of live fire carries a number of inconveniences and even some danger.
In antiquity used clay vesselsfilled with olive oil with a cotton wick. Later, similar lamps were used on the Caspian coast, only petroleum products were used as fuel. By the way, the first wax candles appeared only in the Middle Ages and were considered quite an important invention for their time.
Later with the development of science, many scientists beganfight the solution to this problem. One of them was Leonardo da Vinci, who brought a lot of ideas to science. It can also be partly considered to be the one who invented the first light bulb. Although it was a kerosene lamp, he just refined his ideas. But the problem remained the same - open fire next to the fuel supply, in fact, made it incendiary bottle.
Incandescent bulb
As mentioned above, the invention of the light bulb -This is a long process of work. In the 19th century, the first prototype of a safe lighting device appeared. He was made by a Russian electrical engineer and scientist Pavel Nikolaevich Yablochkov. It was Yablochkov - the one who invented the light bulb. Also on his account and the first electric candle. His invention had many drawbacks, first of all, inconsistent light output and low service life. But, nevertheless, they began to be used on a massive scale to illuminate the streets, as well as important objects of Russia: theaters, shops, central squares, etc.
However, in fairness it should be noted thatThe question is, who invented the light bulb, you can not call only one name. After all, the device itself has come a long way of evolution. In the period from 1840 to 1870. Many scientists worked on the creation of an effective electric lighting device, but there were no results until in 1872, Russian engineer Alexander Lodygin smiled luck. He is the one who invented the incandescent lamp. Already in 1873, two Lodygin bulbs appeared on the streets of St. Petersburg.
The American scientist knew about these achievements.Thomas Edison. He used Lodygina's work, and tried to improve it by solving the problem of longevity. He still found the desired composition of the coal filament, which allowed the lamp to burn for several hundred hours. He, too, can be attributed to the inventors of the lamp, although he worked more on improvement, combining the research of various scientists.
