Evolution of the Alphabet
COVID-19 variants, which are labeled with Greek letters when becoming a variant of concern, normalized their usage. From the Alpha variant in the UK, to the Delta variant that spread from India to become the dominant global strain, the Greek alphabet was everywhere. Seemingly overnight, the Omicron variant discovered in South Africa has now taken the mantle as the most discussed variant.
But the Greek alphabet is used in other parts of our lives as well. For example, Greek letters are commonly used in mathematics and science, like Sigma (Σ) denoting a sum or Lambda (λ) used to represent the half-life of radioactive material.Evolution of the Alphabet
