 Thomas Edison

Explanation: In his 84 years, Thomas Edison acquired a record number of 1,093 patents (singly or jointly) and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras. He also created the world's first industrial research laboratory. Born in 1847, Edison would witness tremendous change during his lifetime. ... Edison invented or refined devices that made a profound impact on how people lived. The most famous of his inventions was the incandescent light bulb (1878), which would revolutionize indoor lighting and forever separate light from fire. Edison realized that the problem with Swan's design was the filament. A thin filament with high electrical resistance would make a lamp practical because it would require only a little current to make it glow. He demonstrated his light bulb in December 1879. Thomas Edison created many inventions, but his favorite was the phonograph. While working on improvements to the telegraph and the telephone, Edison figured out a way to record sound on tinfoil-coated cylinders. In 1877, he created a machine with two needles: one for recording and one for playback.

the first lok sabha in 1951 had 22 women mps. the current lok sabha has 66. in the span of 54 years and 16 lok sabha elections it amounts to a three- fold increase in the number of women mps that made their way to the lower house of the parliament. from 5% in 1951, women mps constitute 12.2% of the lok sabha today. the rise in numbers has been steady through the years, both in absolute numbers and percentages. the notable exceptions have been the dip in numbers during the 6th lok sabha in 1977, the 9th lok sabha in 1989 and most recently the 14th lok sabha in 2004. the trends show a marked and steady increase from 1991 onwards to the present lok sabha. the 1991 figures show a jump from 5% in the previous lok sabha to 7% and the steady increase from thereon (except for 2004). it would be interesting to understand the factors for this watershed year and continuous rise and also the fall in numbers during 2004.

the average representation of women mps( 12.15%) is higher than the national average of women mlas in state assemblies, which stands at a dismal 9%. while the numbers have increased over the years, the percentage of women that make up the lok sabha even today is not a figure to be proud of, especially when the ideal number should be at 33% at least. we still have a long way to go.

central to the question of women’s representation in lok sabha is the appetite for women to take the political plunge and jump into the fray along with and against male candidates, getting tickets from their respective parties to contest elections and finally winning the seats that they contest. while popular perception might be that few women are willing to or have taken the political plunge, number of women contestants tells an interesting story. between 1957(the earliest data available) and 2015, the total number of women contestants has increased from 45 to 668. that is a whopping 15 fold increase in the number of women contesting. if we looked at the data for male contestants for the same years, the number has increased from 1474 to 7583, a five- fold increase. the 15 fold increase in women contestants indicates towards the growing appetite for women to enter the political fray and willingness to be part of political decision-making.
