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.

What unique sound does Morton Einer hear while skating on thin ice?

• The sound of water flowing

• The sound of birds chirping

• The sound of ice cracking and vibrating

• The sound of wind blowing

How does Morton Einer determine the thickness of the ice?

• By checking the weather forecast

• By listening to the pitch of the sound produced by the ice

• By observing the color of the ice

• By measuring the temperature of the air

What is the first warning signal that the ice is thin?

• The ice becomes slippery

• The first crack appears

• The ice starts to melt

• The ice turns white

What is the 'coincidence frequency' mentioned by Morton?

• A weather pattern affecting ice formation

• A type of ice skating technique

• A musical note played while skating

• A mathematical calculation of ice thickness

What motivates Morton Einer to continue skating on thin ice?

• The opportunity to combine math and nature
