PlanetGeo: The Geology Podcast

In this episode of PlanetGeo, we chat with Dr. Stefanie Tompkins, the director of DARPA, about her incredible journey from geologist to leading one of the most innovative research organizations in the world. We discuss everything from her early passion for geology and the unexpected ways it prepared her for a career in national defense, to DARPA's groundbreaking advancements, including the surprising origins of the mRNA vaccine research. Dr. Tompkins shares her unique insights on the multidisciplinary nature of geology, the value of failure, and the thrilling yet intensive environment at DARPA. This conversation provides a fascinating glimpse into how geoscience intersects with national security and cutting-edge technology.Download the CampGeo app now at this link.

In this episode of Planet Geo, we dive deep into the fascinating topic of the age of the Earth and how planets form. We talk about why the age of the Earth is estimated to be around 4.55 billion years and the scientific methods behind determining this age, dating back to the 1955 discovery by Claire Patterson. We discuss the processes involved in planet formation from the solar nebula, the role of uranium and lead isotopes in dating rocks and minerals, the impact of planetary events such as the formation of the moon, and why Earth's active geological processes make it difficult to have original rocks from its formation. We also compare the precision of dating meteorites with dating Earth and explore concepts like the nebular theory, melting events, and planetary isochrons. By the end of the episode, we hope to provide a clear understanding of the complexities and fascinating science behind how our planet, and planets in general, come to be and how we determine their ages.Download the CampGeo app now at this link.
