Mark Zuckerberg

Mark Zuckerberg, the man of the hour and Time person of the year, 2010, is the founder and CEO of Facebook. His creation is on road to become one of the most valuable tech companies of the world as Facebook debuts at the Nasdaq stock exchange on 18th May, 2012. At $38 per share, the Facebook has a market capitalization of $104 billion, making it not only one of the biggest in Silicon Valley, but one of the biggest in the world. Mark's 443 million shares are worth $16.9 billion at $38 a share.

In the filed listing it was revealed that Facebook's revenue was an astounding $3.7 billion while it generated $1 billion in profit. Mark himself earned a handsome base salary of $500, 000 amounting to an annual $1.7 million pay package. Owning 28 % share of Facebook, he will be worth 28 billion USD once the company becomes public and will be standing at front in the queue of richest persons on the planet.

Born on May 14, 1984 to Edward Zuckerberg and Karen Zuckerberg, Mark was a child prodigy, programming and creating games at the age, when one is usually playing them. He repeatedly asserted his extraordinary potential as a computer programmer through different inventions. In his early teens he created a music player named Synapse as a school project using some help from a friend, which used artificial intelligence to understand one’s taste in music and created a playlist accordingly. Software bigwigs like Microsoft and AOL tried to buy it and even recruit Mark. But he refused both. Instead he went to Harvard in 2002. On Feb 4, 2004, with the help of his roommates, Dutsin Moskovitz and Chris Hughes and using the finance provided by another friend Eduardo Saverin, he launched what was called then, The Facebook. It was an instant hit, and soon made Mark the next big thing.

In 2007, he was named as the world’s youngest billionaire and continues to dominate the internet space like no one else. His site, which has ubiquitous presence all across the globe, has now over 850 million members, which in terms of population can be termed as the third largest entity after China and India. A man of radical notions and tremendous genius, Mark wants the world to be a more open place, where every person is connected to other, sharing their personnel lives and dreams that his invention, Facebook would be successful in doing that.

Charles Darwin

Charles Robert Darwin, FRS (12 February 1809 – 19 April 1882) was an English naturalist and geologist, best known for his contributions to evolutionary theory. He established that all species of life have descended over time from common ancestors,and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s the scientific community and much of the general public had accepted evolution as a fact. However, many favoured competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's uniformitarian ideas, and publication of his journal of the voyage made him famous as a popular author.

Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay which described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. In 1871 he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals. His research on plants was published in a series of books, and in his final book, he examined earthworms and their effect on soil. In recognition of Darwin's pre-eminence as a scientist, he was honoured with a major ceremonial funeral and buried in Westminster Abbey, close to John Herschel and Isaac Newton. Darwin has been described as one of the most influential figures in human history.

Mohandas Karamchand Gandhi

Mohandas Karamchand Gandhi was born on October 2, 1869 in Porbandar, India. He became one of the most respected spiritual and political leaders of the 1900's. GandhiJi helped free the Indian people from British rule through nonviolent resistance, and is honored by Indians as the father of the Indian Nation.

The Indian people called Gandhiji 'Mahatma', meaning Great Soul. At the age of 13 Gandhi married Kasturba, a girl the same age. Their parents arranged the marriage. The Gandhis had four children. Gandhi studied law in London and returned to India in 1891 to practice. In 1893 he took on a one-year contract to do legal work in South Africa.

At the time the British controlled South Africa. When he attempted to claim his rights as a British subject he was abused, and soon saw that all Indians suffered similar treatment. Gandhi stayed in South Africa for 21 years working to secure rights for Indian people.

He developed a method of action based upon the principles of courage, nonviolence and truth called Satyagraha. He believed that the way people behave is more important than what they achieve. Satyagraha promoted nonviolence and civil disobedience as the most appropriate methods for obtaining political and social goals. In 1915 Gandhi returned to India. Within 15 years he became the leader of the Indian nationalist movement.

Using the principles of Satyagraha he led the campaign for Indian independence from Britain. Gandhi
