What If Numbers Aren’t Invented—but Discovered?

From Oak Ridge, Tennessee, AMSEcast host Alan Lowe sits down with geologist and paleontologist Dr. Jan Zalasiewicz, chair of the Anthropocene Working Group and author of How to Read a Rock. Their conversation explores how rocks and minerals form and what they reveal about Earth’s history, from the rock cycle and earthquakes to ancient climates recorded in stone. Jan explains how life, human activity, and materials like bricks and concrete have reshaped geology, and how coal, oil, and gas fit int...

Railroads: an origin story

Author Jay Feldman and Alan Lowe, Director of the AMSE Foundation discuss his book, When the Mississippi Ran Backwards.

Alan Lowe is joined in this episode of AMSEcast by Dr. Robin Andrews, volcanologist, science journalist, and author of How to Kill an Asteroid. Dr. Andrews explores how modern planetary defense blends cutting-edge detection networks, such as NASA’s NEO Surveyor, with active deflection efforts like the DART mission, which successfully shifted an asteroid’s orbit. He also delves into theoretical approaches, including gravity tractors and even nuclear options as last-resort strategies. While comets...

Michele J. Gelfand is the John H. Scully Professor of Cross-Cultural Management Professor of Organizational Behavior and Psychology at Stanford Graduate School of Business. Her book, RULE MAKERS, RULE BREAKERS: How Tight and Loose Cultures Wire Our World takes readers on a journey through a variety of human cultures, exploring unique a multi-faceted glimpse into the world around us and ourselves.

Host Alan Lowe continues AMSEcast’s exploration of 250 years of American innovation with Smithsonian experts Harold Wallace Jr., Dr. Eric Hintz, and Tim Pula. Together, they trace invention from Benjamin Franklin’s experiments to modern breakthroughs, highlighting the Smithsonian’s exhibitions, collections, and hands-on learning at Spark!Lab. The discussion spans collaboration with the Library of Congress, the role of failure in creativity, and how patents shape (but don’t define) innovation. Th...

Dr. Robert Hettich is a pioneer in bioanalytical mass spectrometry. In this episode of AMSEcast, he describes how microbiomes form, vary across the body, and influence digestion, immunity, and overall health. Dr. Hettich also explains metaproteomics, the study of microbial proteins, to reveal how microbes function beyond their genes as well as their applications from human health to environmental cleanup and bioenergy. Inspired by his daughter’s experience with Crohn’s, Robert Hettich is especia...

Dr. Rita Colwell

Railroads have shaped America’s growth, technology, and daily life for nearly two centuries. In this episode of AMSEcast, Alan talks with Dr. Albert Churella of Kennesaw State University about how innovations such as the automatic knuckle coupler, Westinghouse’s air brake, and the move from steam to diesel transformed safety and efficiency. Dr. Churella explains how signaling, centralized traffic control, and GPS-based Positive Train Control modernized operations. While U.S. passenger service la...
