#TSAP (The Separations And Partitions, May 13, 2017):

Have you ever received a partly garbled email? Might mixtures be made of mixtures? Are you a separate being? Do you stand ‘in’ history? How is coming-together different from mixing? Is it possible to separate out the constituents from a mixture without knowing what they are? Why does the chiral environment of the body matter? How difficult is pure separation, & why? Can separation or decoding be done in real time? Is separation trivial after mixing? Do different groups constrain individual identities differently? Can partitions be constructions? Why is vote-to-seat conversion so difficult in elections? Does noise have statistical properties? How are filters designed? Do signals always have a continuity property? Why is it so difficult to factorize into two large prime numbers? Can individuality be dissolved (in, say, a mob)? What is the opposite of a mob? Can certain systems be made nearly impossible to partition? What is the future of separations and partitions: Will quantum computing force change in encryption? How would enantiomers be separated? Would entry and exit barriers be lower in several contexts? SynTalk thinks about these & more questions using concepts from chemistry (Prof. Ravi Bhushan, IIT Roorkee, Roorkee), mathematics & statistics (Prof. Rajeeva L. Karandikar, Chennai Mathematical Institute (CMI), Chennai), & social sciences (Prof. Gurpreet Mahajan, JNU, New Delhi).

SynTalk is pleased and privileged to have hosted the following SynTalkrs (in alphabetical order) on its #TSAP show.

Prof. Ravi Bhushan (chemistry) is at the Indian Institute of Technology Roorkee (IITR), where he has served as Professor In-Charge Finance & Planning, Dean of Students Welfare, Member of Board of Governors, & the Head of the Chemistry Department. He received his Ph.D. from University of Jodhpur (1978) working on the chemistry of wildly growing medicinally important plants of Rajasthan desert. He then joined the then University of Roorkee, & subsequently went on to do his post doctoral research at Washington State University, USA. His key research areas are liquid chromatography, resolution of racemic pharmaceuticals, & peanut proteins (primary structures of storage proteins of peanut, brassica, and soybean). He developed the de novo method of chromatographic resolution of DL-amino acids & its application for several racemates of pharmaceuticals, which is now an established approach in chemical literature. He is currently working on separation of excess enantiomers from non-racemic mixtures in a totally achiral environment. He has authored two books – ‘Stereoisomerism’ (1991), & ‘Amino Acids & Chromatographic Separation & Enantioresolution’ (2010). He was awarded the ‘Alexander von Humboldt Fellowship’ by the AvH-Foundation, Bonn, Germany (1988), and the ‘European Economic Community Fellowship’ (1992), and was also elected as the Fellow of National Academy of Sciences, India (NASI) in 2001, ‘Chartered Chemist’ and ‘Fellow Royal Society of Chemistry, London’ (CChem FRSC) in1993. As part of the fellowships, he worked in Germany at University of Giessen, the University of Oldenburg, & in UK at the University of Bristol. Also, Prof. Bhushan is a member of the editorial board of ‘Biomedical Chromatography’ (John Wiley & Sons, UK), ‘Bioanalysis’ (Future Science Group, UK), and ‘Acta Chromatographica’ (Akademiai Kiado, Hungary). At IITR, he received the Outstanding Teacher Award  (2007) & also founded the ‘Intellectual Property Rights Cell’ (2000). Being the coordinator of this cell, he organized several Conferences and Workshops on IPR, and was the Convener of the Committees which formulated IPR Policy (2003) and IITR Policy on Plagiarism (2012).

Prof. Rajeeva L. Karandikar (mathematics, statistics) is the Director of Chennai Mathematical Institute (CMI), Chennai, where he joined as the Distinguished Professor in the year 2010. He obtained his M. Stat. (1978) and Ph.D. (1981) from the Indian Statistical Institute (ISI), Kolkata and went on to do his post doctoral research at University of North Carolina, Chapel Hill, USA. His key research areas include stochastic calculus, filtering theory, Markov processes and Martingale problems, limit theorems, Monte Carlo techniques, queuing theory, game theory, & theory of option pricing. Before CMI, he was the Professor (1989-2006) & Head (2000, 2004-06) at ISI, Delhi, and also worked at Cranes Software International Limited for four years (2006-2010). He has co-authored two books with Prof. G. Kallianpur namely: White Noise Theory of Prediction, Filtering and Smoothing (Gordon and Breach, London, 1988) and Introduction to Option Pricing Theory (Birkhauser, Boston, 2000). He is a Fellow of Indian National Science Academy (INSA, 2005) and Indian Academy of Sciences (IAS, 1994), and was also awarded the Young Scientist Medal by INSA (1985), the Shanti Swarup Bhatnagar Prize in Mathematical Sciences (1999), the Prof. C. R. Rao National Award in statistics by Government of India (2000), & and the P. C. Mahalanobis Gold Medal by Indian Science Congress (2014). Prof. Karandikar has been an editor of ‘Sankhya’ and has been on the editorial boards of Annals of Probability and Journal of Statistical Planning and Inference. He has worked on development of proprietary Blockcipher algorithms for Indian defense services and has been involved with opinion polls and exit polls in India since 1998 (having worked with India Today, Doordarshan, CNN-IBN, & ABP News for these polls).

Prof. Gurpreet Mahajan (social theory, political theory) is Professor of Political Science at the School of Social Sciences, Jawaharlal Nehru University (JNU), New Delhi. Currently, she is also the co-ordinator of the DSA (Department of Special Assistance) programme of the Centre for Political Studies, JNU. Her major areas of study are philosophy of social sciences and social and political theory with particular emphasis on hermeneutics, democratic theory, multiculturalism, religion and state, & civil society. She has written extensively on issues of difference and diversity, religion and state, civil society and democracy. Over the years she has received of a number of fellowships, including, a Senior Fulbright scholarship at Columbia University, New York, and University of Chicago and a post-doctoral fellowship, under the Foreign And Commonwealth Office Award, at the University of Hull, England. She has been a Visiting Fellow at the University of Toronto, Canada, and Maison des Sciences D’Le Homme, Paris. Her publications include ‘Explanation and Understanding in the Human Sciences’ (OUP, 1992; 2e 1997; 3e 2011), ‘Identities and Rights: Aspects of Liberal Democracy in India’ (OUP, 1998), ‘The Multicultural Path: Issues of Diversity and Discrimination in Democracy’ (Sage, 2002), and ‘India: Political Ideas and the Making of a Democratic Discourse’ ( Zed Books, 2013). Besides this, she has edited five books and published over fifty articles. She is on the editorial board of several national and international journals, such as ‘Political Studies (U.K.)’, ‘Journal of Gender Studies (U.K, since 1996)’. Besides academic publications, she has also written regularly for several leading Indian newspapers.
