Evidence:  Why Do Nutcrackers Work? (Podcast)
Running Time:
00:11:17
An interview with science historian Richard Carrier.

It's not enough to know that a nutcracker works; a scientist needs to know why. Historian Richard Carrier recounts how, in ancient Greece, pondering the nutcracker led to the physics of levers. He describes how Aristotle and others shaped the beginnings of Western scientific thought: the notion that knowledge of the natural world relies on being able to question, test, reproduce and improve the accuracy of what's believed to be true. He explains why he sees science as a practice rooted in values, how it protects us from our own erroneous tendencies, and why questioning authority helps foster scientific thinking.

Evidence:  Ancient Astronomy, Modern Knowledge (Podcast)
Running Time:
00:15:28
An interview with Isabel Hawkins, Co-director/Research Astronomer, UC Berkeley Space Sciences Laboratory; Co-director, NASA Sun-Earth Connection Education Forum.

When astronomer Isabel Hawkins began exploring the astronomical work of Native Americans, their knowledge broadened her view of the night sky. She's since discovered several scientists incorporating the work of native people, both modern and ancient, into their current-day research. Isabel describes how she sees science as a cultural construct, the value of learning from personal experience, and that evidence comes in many forms.
