Hello mathematician! I am working my way through a curious monologue: Groups acting on Graphs (by Dicks & Dunwoody). Dunwoody is one of the giants of Group Theory and low dimensional topology. His style of writing is reminiscent of Serre (another stalwart in this... by Ashani Dasgupta

Hello mathematician! I was playing with a square. What if I glue the opposite edges of the square? If I glue one pair of edges, we get a cylinder. (Ah! Are you wondering about the rules of ‘gluing’?) Also see: Festival of mathematics at Cheenta this week Or: Download... by Ashani Dasgupta

This is a part of Thousand Flowers Pre-Olympiad lectures at Cheenta. It is an experiment to teach percentage arithmetic, euclidean geometry, rational and irrationals and computational software tools in an interdisciplinary manner. We extensively used GeoGebra and plan... by Ashani Dasgupta

Hello mathematician! I do not like homework. They are boring ‘to do’ and infinitely more boring to ‘create and grade’. I would rather read Hilbert’s ‘Geometry and Imagination’ or Abanindranath’s ‘Khirer Putul’ at that time. Academy Award winner Michael... by Ashani Dasgupta

We are interested to understand the structure of a group G (is it abelian, or a product of abelian groups, or a free group of some kind etc.). In general, this is a (very) hard question. One strategy is to let G act on some well known (topological) space. Often by... by Ashani Dasgupta

Recently, French mathematician Cedric Villani’s team came up with ’21 measures for the teaching of Mathematics’. I read through the report, with great curiosity and happily noted that Cheenta’s Thousand Flowers program has already implemented...
