Today’s date is the 2nd of February, 2022 or 02/02/2022. All those twos and zeros are rather satisfying. The Pythagoreans aimed to describe the universe using numbers and shapes. They regarded 2 as representing the female principle; however, they did not have zero as a number. It seems strange now but it was not an obvious concept at all. The idea of a positional number system with place value emerged slowly over centuries, typically with a placeholder symbol representing ‘nothingness’, and not regarded as a number in its own right. Probably the most advanced of these systems was the Mayans, who were totally detached from the Graeco-Roman and Indian advances in mathematics, but could calculate efficiently into the millions. It was not until the 7th century CE in India that the illustrious mathematician Brahmagupta established the arithmetical rules for zero that we use today.
Two and zero – an image of duality: matter and antimatter emerging from the void. Have a good day, and look out for 20/02/2022 in a couple of weeks!
