The Webinar on Mathemagical Humor took place on Thursday, January 21st, 2021 from 2 pm until 3:30 pm, with the mathemagician Andres Rieznik from Argentina, as our invited speaker. This virtual event was free and open to the general public.
The invited speaker presented a mathemagical show with several fascinating tricks mixed with math jokes. Andres Rieznik squared numbers of two, three and even four digits faster than a calculator; identified the day of the week in which a participant was born only by knowing their date of birth; made a magic square with a two-digit number that a participant randomly selected; indicated the missing digit of a number resulting from multiplying by 27 done by two participants; and showed a trick with 4 pieces of paper with the letters A, B, C and D. The speaker also explained the math secrets behind some of these tricks, that appear in his book “Mental Athletics.”
