Dr. Emily Kern is a recent graduate of Princeton’s Department of History, and she visits us this week to show us the twists and turns of paleoanthropology over time. That is, how have scientists understood humanity’s evolution as we learned more and more about the world? Hear how, until very recently, most everyone thought humans evolved out of Asia–an idea borne by tracing Indoeuropean languages to their roots and assuming humans came from the same place as language does. The international endeavor to trace our evolution back to Africa has taken both explorers (the avid and the methodical) and better methods for dating fossils to 100,000 – 1 million years. Like many fields of science, paleoanthropology has become increasingly complicated the more we discover.

1/16/18 Show feat. Florencia Pierri on Exotic Animals in the New World

This episode, we interview Florencia Pierri, graduate student in Princeton’s Department of History and historian of science, to learn about reconciling the taxonomy of the Old World with the new discoveries of European explorers. How did mythical creatures–unicorns, dragons, mermaids–come into popular consciousness? How did sailors and merchants comprehend the new creatures they met in the Americas and on the seas? Turns out the absorption of a whole new evolutionary tree is a difficult undertaking for a culture that thought it already knew every animal! Join us to learn why armadillos and hummingbirds were so prized by Europeans, how the Jesuits felt about skunks, and how unicorns gradually receded from maps of the world.

This week on These Vibes, Stevie discussed research with fellow observational cosmologist, Eve Vavagiakis. Eve is a researcher on the Atacama Cosmology Telescope, aka ACT, located in the Atacama desert in Chile. She discusses cosmology and astrophysics, her research and how she makes her measurements, and answers excellent listener questions.

1/2/18 Show feat. Dr. Michael Gordin on Fringe Science: Demarking the Boundaries of Mainstream

Today we hosted Dr. Michael Gordin, Princeton science historian and expert on fringe scientific theories. Central tenets of science are widely regarded as mainstream, but newer or more radical theories sit further away from consensus. These fringe topics supply science with new ideas, but they also spawn even further removed theories—everything from Bigfoot to UFOs to self-help quantum mechanics. In this undefined range between established and untested research, scientists need to establish what sets the bar for “real” science. In a remarkable perspective, Dr. Gordin connects Scientology with a cataclysmic Venus encounter that supposedly occurred in 1500 BCE, and shows us how appreciation for science drives the many kooky theories that bother scientists.
