Our life is a result of series of choices that we make time to time. . The paradox in it is that all of us wish to make and in fact make right choices according to us. But at times we realize that our choices were wrong. People who are successful have also made wrong choices. But every time they realize they made a wrong choice they gather up courage to correct the wrong choices into learning experiences and make new inventions. This is what great people’s life teach us. There is no one found in the history that was successful without an experience of failure. It doesn’t mean that Failure is mandatory for success. But it simply means that even failure can be turned into success taken in its right sense.

For example the invention of electric bulb. It is popularly known that Thomas Alva Edison invented Electric bulb. But in reality the electric light wasn’t Thomas Edison’s first invention, nor was he the first to create an alternative to gaslight. Electric lights already existed on a streetlight scale when, on this day in 1879, Edison tested the one he’s famous for. Though he didn’t come up with the whole concept, his light bulb was the first that proved practical, and affordable, for home illumination. The trick had been choosing a filament that would be durable but inexpensive, and the team at Edison’s “invention factory” in Menlo Park, New Jersey, tested more than 6,000 possible materials before finding one that fit the bill: carbonized bamboo.

History unfolds the series of inventions made by different Scientists in reaching to the invention of the electric bulb in use today.

The first electric light was made in 1800 by Humphrey Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.

Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.

In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.

The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours. In 1878, Thomas Edison began serious research into developing a practical incandescent lamp and on October 14, 1878, Edison filed his first patent application for "Improvement In Electric Lights". However, he continued to test several types of material for metal filaments to improve upon his original design and by Nov 4, 1879, he filed another U.S. patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," it was not until several months after the patent was granted that Edison and his team discovered that a carbonized bamboo filament could last over 1200 hours. This discovery marked the beginning of commercially manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company began marketing its new product

Lewis Howard Latimer (1848-1928) improved the bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.

In 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.

It is said that there is only one thing that cannot be predicted rightly and that is human destiny because of ever changing human capacity .No teacher can predict what a student would be in future just looking at the performance today. A right choice in the right time can change the entire destiny. Therefore let us not underestimate or block the creativities in our children . But encourage and accompany them to greater success. No matter what the first result is . let us believe in their potentials and creativity.
