The Webinar on The Story of Pascal’s Triangle that is not Pascal’s took place on Thursday, October 7th, 2021 from 2 pm until 3 pm, with Arturo Mena Lorca, Professor of Mathematics at the Pontifical Catholic University of Valparaiso in Chile, as our invited speaker. This virtual event was free and open to the general public.
The invited speaker started the virtual event by explaining that the famous Pascal’s Triangle is actually not a triangle and is not an invention of Pascal either. Arturo Mena Lorca shared six properties of Pascal’s Triangle: the numbers in the “triangle” are natural numbers, there are number 1’s in the edges, the sequence of natural numbers appears twice, it is symmetric, it has a law of formation, and the sum of every row is a power of 2. The speaker showed these six properties through three different perspectives.
