Inside the Invention Factory with Kathleen Carlucci

Given the centrality of uranium to the story of the Manhattan Project, the creation of Oak Ridge, and the ongoing nuclear renaissance, I thought it would be good to learn more about that element, so I spoke on our podcast, AMSEcast, with Tom Zoellner about his fascinating book, Uranium: War, Energy, and the Rock that Shaped the World. I started by asking why uranium is so unique and so suited to creating the chain reactions that are central to both nuclear energy production and the workings of nuclear weapons.

Alan Lowe speaks with Dr. Simon Cordery about the transformative role of railroads in American history. From the Baltimore and Ohio Railroad in 1828 to a national network by 1916, Cordery details how rail shaped commerce, industry, and infrastructure. He also explores regulation, from early oversight efforts to the 1980 Staggers Act, which revitalized the struggling industry. The conversation touches on Amtrak’s dependence on subsidies, the challenges of expansion, and the promise of high-speed rail. Cordery also previews his book on Albert Pullman, a largely forgotten innovator behind the Pullman Company’s early success and a symbol of overlooked entrepreneurial ambition. &nbsp; &nbsp;  Guest Bio Dr. Simon Cordery is Chair of the History Department at Iowa State University and a leading scholar of American labor and transportation history. He previously served as department chair at Western Illinois University and Monmouth College. Dr. Cordery has authored several acclaimed books, including Mother Jones: Raising Cain and Consciousness and The Iron Road in the Prairie State: The Story of Illinois Railroading. His forthcoming work, Gilded Age Entrepreneur: The Curious Life of American Financier Albert Benton Pullman, explores the overlooked legacy of the elder Pullman brother and offers fresh insight into the entrepreneurial spirit of 19th-century America. &nbsp; &nbsp; Show Highlights  (2:14) When railroads first arrived in America and how quickly they spread (6:18) Changes in the business world that supported and continued railroad expansion (7:16) The impact of government oversight as the industry develops (14:47) When deregulation of the railroad industry occurred and the effects it had (19:46) The effects railroads had on labor organization and the labor market in America (22:32) How railroad expansion affected how we keep time throughout the U.S. (24:28) The effect of digital technology on the American railroad industry (31:47) Is high-speed rail a profitable enterprise?

The Salmonid Restoration Foundation's (SRF) 42nd Annual Salmonid Restoration Conference will be in Santa Cruz at the end of April; Dana has been Executive Director for 20 years; the conference is the largest Salmonid / watershed conference in the northwest; 550 people are registered, but it's a challenging time: starting last year, there was a freeze on state employees traveling, and now Federal; Santa Cruz will host the conference at a number of venues; the Klamath Dam removal is the largest dam removal in history - it took decades! The secret? You have to have a big team, and find common ground; after the dam's removal, it took days (!!) for salmon to start to return, and in months, more than 10,000 returned; what does Santa Cruz get out of hosting the conference? Economic impact, plus networking, learning, and history; lessons learned? Regional issues, and urban creek restoration and homelessness; definition of "anadromous" fish; SRF was created to hold the conference, but has expanded to do more. 

An interview on "The Bushwhacker's Breakfast Club" with "Dangerous Dan" & "DJ Spark Plug", airing Friday mornings on KZSC Santa Cruz, California.

Jack Kelly joins Alan on this episode of AMSEcast to talk about his book Gunpowder: Alchemy, Bombards, and Pyrotechnics. They discuss gunpowder’s accidental invention in 10th-century China and its explosive mix of saltpeter, charcoal, and sulfur. Kelly explains how gunpowder shaped science and warfare, fueling revolutions in physics, ending the era of castles, and powering colonial empires. Though once too expensive for civilian use, gunpowder later drove mining and infrastructure projects before being replaced by safer, more powerful explosives like dynamite. Kelly also previews his upcoming book on Thomas Paine, highlighting Paine’s role as both Enlightenment thinker and Revolutionary soldier. &nbsp;  Guest Bio Jack Kelly is an award-winning historian, journalist, and novelist, as well as a New York Foundation for the Arts Fellow.

Gunpowder: From Alchemy to Empire with Jack Kelly

We always celebrate at our museums the rich history of American innovation, but we’re putting a special spotlight on that history as we approach the nation’s semiquincentennial in 2026. To help us with that, we spoke on our podcast, AMSEcast, with Kathleen Carlucci, the Director of the Thomas Edison Center at Menlo Park. Thanks to his host of revolutionary innovations and inventions, Thomas Edison changed our world with technologies like the phonograph, motion pictures, electric light, and the list truly goes on and on. Altogether he obtained 1,093 US patents, and 1,250 patents in 34 other countries. At Menlo Park in New Jersey, Edison gathered an incredible team in one place to conceive and create these inventions, starting the whole concept of research and development and what we call today “Big Science.”

On this episode, being recorded at the National Academy of Sciences Building in Washington, DC, I’m very honored to be joined by Dr. Alton D. Romig, Jr. Al has had a truly exceptional career, full of more awards than I can list today. Most recently, for example, the 2024 IEEE McClure Citation of Honor for engineering leadership, and more positions than I can include today, but they’ve included leadership roles at Sandia National Lab, service as vice president and general manager of Lockheed Martin’s Advanced Development Programs, better known to all of us as the famous Skunk Works. And currently, Al serves as Executive Officer of the National Academy of Engineering.

Noted historian Walter Borneman recently spoke to us about his book, MacArthur at War: World War II in the Pacific. Few characters loom as large in that war than Douglas MacArthur, and Walt’s book gives a terrific look at how this enigmatic man helped lead our nation to victory over the Japanese. After his narrow escape from the Philippines as the Japanese invaded, MacArthur set up his headquarters in Australia in a time that looked very bad for the allies. Walt offers unique perspective on MacArthur’s field of operations as the allies began to turn the tables against the Japanese empire.
