Mathematician uncovers the preference for numbers starting with one and two

A mathematician named Frank Benford noticed that there were more numbers starting with one and two than with seven, eight, and nine. This phenomenon, known as Benford's law, has been observed across various statistical data, including molecular weights, baseball statistics, and bank account balances. Benford's law has even been used in forensic accounting to detect fraud. The mathematician Paul Erdos is also mentioned, known for his extensive collaborations and the creation of Erdos numbers to denote connections between mathematicians. The summary highlights a poignant story of friendship between Steve Strogatz and his math teacher, Don Joffrey, and the missed opportunities for deeper conversation and connection. The story concludes with discussions about waves, infinity, and the book "The Calculus of Friendship" by Strogatz.
