Webinar on Codes, Satellites and Magic

The Webinar on Codes, Satellites and Magic took place on Thursday, November 18th, 2021 from 2 pm until 3 pm, with Elisa Lorenzo Garcia, Professor of Mathematics at the University of Neuchatel in Switzerland, as our invited speaker. This virtual event was free and open to the general public.

The invited speaker explained that correcting errors in the transmission of information is something that we do in a natural way. Elisa Lorenzo Garcia mentioned that a way to guarantee that the information arrives correctly is to send it several times but repeating everything always is not the best option and that’s why we use check digits. The speaker also defined what codes are and shared several applications of codes based on their capability to correct errors when sending information. Elisa Lorenzo Garcia also described how we can use codes to send images to Earth taken by satellites in space and how we can use them to perform a fascinating magic trick.
