Departmental Café Session

The Department of Science and Humanities had its second Departmental Café Session for the Academic Year 2021-22 on the 12 February 2022. The resource person for the evening was Dr. Kala R. Nayak, Registrar and Professor (Mathematics), Don Bosco College of Engineering, Fatorda. She had an interactive session on the topic ‘Matrices’.

    Dr. Kala began her session by introducing the term matrix and what it means in different subjects. She said matrices are used in Geology, Physics and even medical science. She then went on to speak about the types of matrices, i.e, a row matrix, a column matrix and a singleton matrix. She also explained how a graph can be described using a matrix. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. Matrices can be used to know whether a graph is directed or undirected

  Dr. Kala then introduced the transpose of a matrix – a matrix which is formed by turning all the rows of a given matrix into columns and vice versa. She then gave examples of different matrices like the stochastic matrix and doubly stochastic matrix. To make this more interactive and interesting she asked the participants to give examples of stochastic matrices.

  She ended the session by posing three questions to the participants. These got the participants excited and more active.
