Deep Time and Shallow Thermodynamics: How we KNOW the age of the solar system.
Audience: Adults
Description: The age of the solar system (and Earth) has had a long history of contentious debate, most famously in the last decade of the 19th century between Lord Kelvin and his one time assistant John Perry. Today radiometric dating has the precision to detail events during the formation of the solar system and the geochemical evolution of the Earth. I will review how we know the ages of the Solar System and the Earth and how that knowledge has changed our understanding of their formation and evolution. This is not just a story of technology, but also a very human story about how science works and understanding develops.
