A 'Hole in the Wall', literally, has helped scientist and Educationist Dr Sugata Mitra win $1 million international prize, from TED, a global Technology, Entertainment and Design conference held twice each year. Mr Mitra started with the simple concept in 1999. He used computers from NIIT, a computer learning centre where he used to work, and put them up with Internet connections on the walls of a slum in Delhi. He observed children as they tired their hands on these machines, and learn using the Internet and get basic knowledge of various subjects like science and mathematics.
