Dear pariappa. Thank you truly for being such a good uncle and a great human being. I have had some of the most intellectual moments, discussing several physics concepts, thanks to you pariappa. I could accomplish much in my student life with your constant guidance, support and introduction of scientific concepts. You didn't think twice, to help others or teach us when we were kids. I will cherish the memories I have of you. Rest well in next life, pariappa.
