Engineering Podcasts

A floor can carry a fire rating such as REI 60. Almost nobody who walks past it could say what the letters promise. Engineering podcasts are good at closing that gap. They open up the decisions buried inside structures, machines and plants, and let you hear the people who made those decisions measure, argue and second-guess them.

The range is wider than the word suggests. One feed reads suppressor test data to the decimal point. Another walks through European steel codes. A third sits a mine-waste engineer down to remember how tailings were handled. Listeners argue about familiar things:

• In September 2026, a poster in a women-in-tech Reddit thread said they were tiring of AI-heavy coverage.
• In June 2026, an aerospace forum participant preferred video because engineering plots are easier to show than to describe.
• In April 2026, a mechanical engineering commenter liked some episodes of an industry show and considered others essentially product advertising.

Those three complaints make a useful map.

Reading the numbers aloud

• In Episode 300 - AAC 762-SDN-6 Testing Tech Discussion and HK USP 45 Tactical Match LEM Hybrid (08-APR-2026), the host gives a composite suppression rating of 33.5 on a 14.5-inch Knight's Armament SR25. He also explains where each measurement was taken: one meter left of the end cap, and six inches right of the shooter's ear.
• He also tells listeners, "If you have the report up, you can follow along at home." That is the honest caveat. He asks you to look at figure two, and in The Jay Situation's Episode 289 - Stealth Additive Works Tisha 5.56 Testing - Technical Discussion (07-JAN-2026) he describes plans to do his best to accommodate colourblind users of his colour-coded hazard maps.

Audio carries the reasoning, but the plots live on a page you can keep open.

• In EN 1993-1-7, shear lag, where stress fails to spread across a wide plate, becomes a loose T-shirt pulled tight at the sleeves while the hem stays floppy.
• Eurocodes' 18-minute EN 1993-4-2 follows steel after a fire, its cooling shell fighting a still-hot core: "It can snap bolts and tear welds hours after the flames are gone."

When something goes wrong

Failure is where engineering stops being abstract.

• In Episode 139 - 2025 (Process Safety) Wrapped, the hosts recall an ammonia release where the evacuation route ran through the cloud itself. They argue that a muster point chosen for fires may be wrong for a toxic release, and that worn-out windsocks matter.
• In Amplify Your Process Safety's Episode 143 - CCPS Monograph - Process Safety in Business Financial Decisions, Bartlett reads Trevor Kletz's old saying: "if you think safety is expensive, try an accident."

Fire and its aftermath. In Fire Science Show's 239 - Assessing post-fire structural damage in tunnels with Negar Elhami-Khorasani, a firefighter's question drives part of the research: how long must a fire burn before his crew faces collapse risk? The host is open about his agenda, saying he is "championing something which may exist, may not exist, which I try to call wildfire engineering."

• In Restoring a 200-year-old suspension bridge with VolkerLaser, Lee Jackson walks through strain gauges, radiography and grinding into surface cracks. He describes setting out to prove the old ironwork sound and "eventually proving that it wasn't okay."
• The Structural Engineering Podcast's Episode 102 - Navigating Emergency Response Engineering shows the human side. A guest describes finding a man sweeping mud from a flooded basement: "I wouldn't be in there but I can't tell you not to be in there."

The trade floor and the AI question

Professional associations and vendors make much of this genre, and the AI debate runs through their feeds. Listen for who is selling what.

• Advanced Manufacturing Now. In The State of Smart Manufacturing — Advanced Manufacturing Live, the host cites a report finding 34 percent of respondents still in the pilot phase. Rockwell's Andrew Stumpf argues that the adoption curve "signifies we're past this tipping point."
• ASME TechCast. In Where AI Fits in Manufacturing Engineering, guests from HCL Software argue that fixed rules must come first: "Rules are the tracks. But modern AI is not replacing the tracks." That is a software company describing its own approach, and it is worth weighing as such.
• The Systems Engineering Podcast. Jolly Pradhan offers a plainer counterweight: "AI is just a tool and it's not always the right tool."

The people doing the work

Some shows are about careers more than mechanisms.

• Diverse: a SWE podcast. Ep 360: SWE in Space: The Purdue 1 Student Space Mission pairs a professor, Stephen Collicott, with his graduate student, Abby Mezzi. Each has a fluids experiment, and both plan to fly with them. Collicott says Virgin Galactic tells them the flight will be in 2027.
• Behind the Scenes with Bryan. Mining engineering is told through memory. In Episode 199: a conversation with Peter Jenner, the guest recalls when a mill manager oversaw the tailings and, once the waste was pumped out, "it wasn't his problem anymore."
• The Structural Engineering Podcast. In Episode 100 - Max and Zach: Candid Conversations, Max names his biggest lesson in 15 years: load follows stiffness.

For the curious outsider

You do not need a degree for every show here.

• Department of Engineering Science Lectures. This Oxford feed holds recorded lectures, the newest from 2019. In Bubble Acoustics: from listening to the ocean to cleaning medical devices and fighting antimicrobial and antibiotic resistance., Tim Leighton says his device clears dried mouse brain from stainless steel with five seconds of water flow. He says it will be piloted in about 20 UK hospitals. Some passages lean on slides you cannot see.
• Unprofessional Engineering. James and Luke ended the show in 2023 with All Good Things Must Come to an End - Episode 341. Their archive is still a cheerful primer: How Golf Balls Are Made - Episode 340 explains how dimples push airflow separation to the back of the ball.
• EE Times Current. This show assumes more vocabulary. In Neuromorphic Spikes Unify Control and Decision Making, Rodolphe Sepulchre likens good control to a child pushing a swing: "It just pushes from time to time and knows when to push."

Where to start

For a newcomer to codes and ratings: Fire Science Show, 246 - Fire Fundamentals pt. 20 - Fire Resistance Criteria with Piotr Turkowski. Test it on the next door you see.

For a short commute: Eurocodes, EN 1993-4-2. It runs 18 minutes.

For anyone who works near hazardous processes: Amplify Your Process Safety, Episode 139 - 2025 (Process Safety) Wrapped.

For data obsessives with a screen nearby: The Jay Situation, Episode 289 - Stealth Additive Works Tisha 5.56 Testing - Technical Discussion (07-JAN-2026). Keep the report open.

After one episode, ask whether you could explain a single thing more clearly, such as a rating, a failure or a trade-off. If you can, the show has earned the next hour.
