 Hello friends, this is Shri Khan. I am a student of IIT Madras posing my research in Heat Transfer and Thermal Power Laboratory. So here I am here to talk about the essence and the fruitful thing that you get from the NPTEL videos which you are going to see in this website. What I feel is the quality that the education should provide to each student is the motto of this particular website. And I can assure you that the quality of the lectures that are available in this website are in part with the live lectures that you can see in IIT Madras. So since I come from an engineering college which is non-IIT, I really feel that the quality of education that you get here and from this website are really exciting. And in my personal opinion what I want to tell you is please make full use of these lectures which are given by so very big professors and knowledgeable professors who are giving these lectures. And I want you to get some good thing for your research which you are doing or it may motivate you to do something good in your career and good in research. So thank you.
