I think all of you know about Super-30 An IIT Factory......
I will just prsent here about the Life of Mr. Anand Kumar...............
Anand Kumar was born in Bihar. His father was a post office clerk in Bihar. His father could not afford private schooling for his children, and Anand attended a Hindi medium government school, where he developed his deep interest of Mathematics. During graduation, Kumar submitted papers on Number Theory, which were published in Mathematical Spectrum and The Mathematical Gazette.
Anand secured admission to Cambridge University, but could not attend because of his father's death and his financial condition, even after looking for sponsor in 1994-1995, both in Patna and Delhi.
Kumar would work on Mathematics during day time and would sell papads in evenings with his mother, who had started a small business from home, to support her family. He also tutored students in maths to earn extra money. Since Patna University library did not have foreign journals, for his own study, he would travel every weekend on a six-hour train journey to Varanasi, where his younger brother, learning violin under N. Rajam, had a hostel room. Thus he would spent Saturday and Sunday at the Central Library, BHU and return to Patna on Monday morning.
