Dr. A. Majeed

To all who have had the pleasure of interacting with Dr. A. Majeed (popularly known as Majid Khan) or learning from him, he is a living legend. He did his M. Sc in mathematics from Kanpur University in 1976 and joined IIT-Delhi for research in Mathematics. He possesses a rare ability among mathematicians to communicate its perceptions and understanding to his students in a lucid way. His innovative ideas and pragmatic approach has motivated students of all walks of life. He is capable of interacting with the entire spectrum of students. Some of his achievements are as follows: Presented lectures in advance Mathematics in Indira Gandhi National Open University which are still relayed by the Gyan Darshan Channel. He has actively participated in Gyan Sewa Project being run for Rural Punjab students by Mr. H.S. Phulka in the year 2006-2007. He took tutorials of B.Tech Students in IIT Delhi when he was a research scholar there. He taught in DPS R.K Puram for 10 years and played pivotal role in bringing the name of Delhi Public Schools in global mat. He has authored many well recognized books in mathematics. Some of which are IIT-JEE (Rachna Sagar Publication), Algebra and Co-ordinate Geometry (Disha Publication) Trigonometry and Calculus (S.A. Publication).

Mathematics is more philosophical less algorithmic...
