The first book by Dr. Jiten Chandra Kalita, Senior Professor in the Department of Mathematics at IIT Guwahati, Martinak Racket Khon Diya Nohol, is a collection of thirty-four selected essays previously published in newspapers. Shri Kalita—a distinguished teacher and pioneering researcher—began writing for newspapers only during the COVID period, almost quietly and unassumingly. His sensitive writings, marked by a unique style and an unusual choice of subjects, have already won wide admiration among readers. Enriched with the multicoloured experiences of the author’s personal life, reading these essays feels like watching a series of documentaries.
