Roger Penrose
The same year, he became an A.R.S.C and also obtained his BS in Physics and DIC in Mathematics. In 1969, Qadir pursued his MSc in Mathematics, followed by PhD in Mathematical physics and Theory of relativity with the specialisation in Twistor theory, under the supervision of Roger Penrose in 1971. He pioneered the mathematical contributions to the development of Special relativity and the twistor theory, which is the approach to the problems of fundamental physics pioneered by Roger Penrose.
