Heroes are an inspiration for everyone. Here, I will introduce you to unsung hero of India. An IIT Kanpur Engineer who quit his job at Telco and began teaching science to the children cf India. When Arvind Gupta quit his job, his mother came to his defence stating ‘good, now he will do something noble with his life’. He has been inspiring generations of students to learn science with their own hands on ‘Tarang’, the DD show, since the 1980s.
