Interesting Things with JC is a new podcast mini series, with highlight on some of the more interesting historical stories, current events as well as under-told stories.

Interesting Things with JC #1652: "Facebook’s Emotional Contagion Experiment" – Facebook changed the News Feeds of nearly 690,000 users to test whether emotions could spread online without telling them first, and the users’ own posts shifted after the feed was altered.

Interesting Things with JC #1651: "The NERVA Program" – A rocket engine fires in the Nevada desert without burning fuel the normal way, and a uranium reactor heats liquid hydrogen until it blasts through the nozzle; the tests work, the engine restarts, but the Mars rocket never leaves Earth.

Interesting Things with JC #1650: "Ion Drives" – An engine produces less force than a postcard weighs, yet it keeps pushing a spacecraft across billions of miles of space; chemical rockets burn hard and stop quickly, while ion drives keep accelerating atoms through a vacuum long after the violent launch is over.

Interesting Things with JC #1649: "Ernst Stuhlinger" – A NASA engineer answers a nun asking why Mars missions matter while people are starving on Earth, and the answer comes from a former V-2 rocket scientist whose later work moves spaceflight away from explosive force and toward ion propulsion that pushes for years.

Interesting Things with JC #1648: "Why Are Manhole Covers Round?" – A heavy cover sits over a city access hole, but its shape keeps it from dropping into the tunnel below; the same circle also spreads traffic force and lets workers roll 90-to-250-pound cast iron through the street. This episode is inspired by Mr. Paul.

Interesting Things with JC #1647: "Fermilab" – Scientists send neutrinos through solid rock from Illinois to distant detectors without a tunnel, while bison graze above one of America’s major particle physics laboratories and underground machines recreate conditions from moments after the Big Bang.

Interesting Things with JC #1646: "Electrostatic Propulsion" – A fixed-wing aircraft flies with no propeller, no combustion, and no exhaust while electric fields push ionized air across its wings; the same thrust pattern is already moving spacecraft through vacuum and spreading into quiet drones, high-altitude platforms, and long-duration electric space missions.

Interesting Things with JC #1645: "The Gulf of Tonkin" – U.S. destroyers fired into the dark after reporting a second North Vietnamese attack, but the ships had no confirmed targets, pilots found no enemy vessels, and the disputed incident became the legal basis for expanding the Vietnam War.

Interesting Things with JC #1644: “Krafft Ehricke” - He is the rocket engineer who proposed lunar mining, orbital fuel depots, and space based solar power decades before modern commercial spaceflight. From the V-2 rocket program at Peenemünde to America’s Atlas rocket program, Krafft Ehricke helped shape ideas that are now influencing the future of space exploration.

Interesting Things with JC #1643: “Why Are Stop Signs Octagons?” - Engineers choose an eight-sided stop sign for a reason! This episode explores the rise of automobiles, the chaos of early American roads, and how the octagon became one of the most recognized warning symbols in the world.
