metal asteroid Psyche
Dr. Zoe Landsman
Astrophysics and Astronomy | Physics
We welcome special guest Dr. Zoe Landsman back to the show to tell us about the metal asteroid Psyche and the eponymous mission to visit it. We get an update on an observational test of one of the central pillars of cosmology, and have some spaceship/asteroid/comet trivia to stump the astroquarks.
The Exponential Function
If you want to get somewhere fast, then consider the exponential function, especially if "somewhere" is very large numbers. Whether it's growing your savings, your debt, your population, or the number of nuclear reactions in the core of a star, the exponential function is here to turn a modest sounding 5% growth per whatever, into a doubling of your numbers in just 14 whatevers. Turn one into 1 million in just one year with just a 4% growth per day. The Exponential Function provides a great return on and conclusively shows that Thanos is a complete moron and certainly never had a math class. Exponential Function, double your pleasure, double your fun. (Doublemint Gum)
