'Mathematics is the language', said Paul Samelson, the greatest economist of the 20th century.He was the man who made economics an 'accountable' subject. By using mathematical tools, he elevated the status of economics from the status of a qualitative subject to a quantitative science which even attracts people from other academic streams. Paul Samuelson, after contributing to the world a whole set of theories that reformed economies and economics, passed away yesterday at the age of 94.His students remember him as the inspiring professor who enlightened the though process of his students, a person who loved to travel in his Beetle car. It was his great self who set up the famous Economics Department of MIT, the ultimate destination and desire of all people who are passionate about economics. Samuelson's times were marked by the intellectual debates that MIT had with the Chicago school who are supporters of Milton Friedman. Now, though the man himself has returned back to soil, he will live in the hearts of millions of students, researchers and policy makers who would say, these were the times of quantitative science, these were the times of samuelson.
