Summary
The Slippery Science: The Physics of Ice podcast episode hosted by Neil deGrasse Tyson and co-hosts explores the properties of ice and its impact on winter sports. The episode features a guest speaker, Lori Winkless, who sheds light on the slipperiness of ice and the quasi-liquid layer that forms on its surface, which decreases friction as the temperature increases. The hosts discuss different types of ice and their behavior at different temperatures, as well as pressure melting and the changing behavior of ice at different temperatures. They also touch on the impemba effect and the physics behind curling, including the infamous "broomgate" controversy. In addition, the podcast delves into the impact of climate change on glaciers and freshwater systems, investment opportunities in artificial snow production, and the future of ice research.
The conversation covers a wide range of topics related to ice, including the formation and movement of glaciers, the blue color of glacier ice, and the preservation of prehistoric creatures and DNA in glaciers. The hosts also discuss the differences between ice and compacted snow, the impact of climate change on glaciers, and the possibility of investment opportunities in artificial snow production. They also touch on the potential for designing surfaces to efficiently form ice and prevent ice formation on surfaces like airplanes.
Overall, the Slippery Science: The Physics of Ice podcast episode provides fascinating insights into the science and nuances of ice and its impact on sports and the environment. The hosts and guest speaker offer a wealth of knowledge and expertise on the topic, making this episode a must-listen for anyone interested in the physics of ice.
