Samantha Yammine, PhD on Instagram: "every credit card # follows this rule 🤯 It’s called the Luhn algorithm. Give it a try with yours! What a treat to have THE math queen @onlinekyne on the latest episode of the Curiosity Weekly podcast talking all things math — and why it pairs so beautifully with drag 💄✨ This episode also has the highly requested follow-up to our microplastics story, plus an interesting new study on how caffeine influences performance.
