Using Math to Skate On Thin Ice

Morton Einer, a mathematician, combines his love for skating on thin ice with his expertise in mathematics to understand the sounds and conditions of ice. He listens to the pitch of the ice to determine its thickness and safety, using his knowledge to calculate the coincidence frequency. Morton's passion for skating has led him to explore over 1800 bodies of water, where he applies his mathematical skills to ensure safety and enjoy the thrill of skating on thin ice.
