3.1 seconds. That’s the exact time George Goble calculated for a cup of water to hit boiling in a run-of-the-mill office microwave back in 1982.
He won the bet. Cleanly. No fuss.
And here’s the kicker — this wasn’t some party trick. Goble, a NASA engineer with a PhD in aeronautical engineering, crunched the numbers using finite-difference methods on a supercomputer. We’re talking early ’80s tech, when “high-performance computing” meant tape drives humming louder than a rock concert. But Goble? He treated that microwave like a rocket nozzle simulation.
Look, in an age of ChatGPT hallucinations, Goble’s stunt hits different. It screams architecture: layers of physics models stacked on crude hardware, spitting out truth. No hand-wavy approximations. Just cold, hard simulation.
Who the Hell Was George Goble?
Born in 1939, George Harry Goble climbed from Purdue undergrad to NASA’s Lewis Research Center — now Glenn — where he tackled the beast of computational fluid dynamics. CFD, for the uninitiated: math that predicts how air screams over wings at Mach speeds.
By the ’70s, he’s wiring up Cray-1 supercomputers, those behemoths costing millions, guzzling kilowatts for problems that’d make your MacBook sweat today. Goble co-authored papers on numerical methods for transonic flows. Dry stuff? Sure. But it’s the bedrock under Boeing’s wings and Space Shuttle heat shields.
He stuck around NASA till retirement, then tinkered with Linux clusters — yeah, the guy bridged mainframes to open-source zealotry.
“Goble became widely known outside the engineering community for his microwave popcorn experiments and his Thanksgiving turkey recipe, which involved deep-frying a turkey in 37 seconds.”
That’s from his Wikipedia page, capturing the duality: suit-and-tie HPC wizard by day, backyard physicist by night. But don’t romanticize — this was no meme lord. It was method.
Short version? Goble died October 1, 2024, at 84. Hacker News lit up with 94 points and 18 comments, folks swapping tales of his legend status.
Why Does a Microwave Bet Still Echo in Dev Kitchens?
Because precision scales. Goble’s 3.1-second calc? He modeled heat transfer, dielectric losses — all on a VAX or Cray, eyeballing constants from microwave manuals.
Fast-forward — or don’t, since that’s forbidden — to now. DevOps pipelines chase that ghost: CI/CD jobs that predict build times to the millisecond, or Kubernetes autoscalers nailing load spikes. Goble prefigured it. His “bet” was DevRel before DevRel existed, demoing sim fidelity to skeptics.
But here’s my unique dig: while AWS hypes infinite scale, Goble reminds us physics bites back. Remember the 2021 AWS outage? A single control plane hiccup cascaded because models ignored tail latencies — Goble-style granularity could’ve flagged it. Corporate clouds spin PR fairy tales; Goble computed reality.
Skeptical? Check the HN thread. One commenter recalls Goble’s turkey fry: 40,000 BTU propane torch, 3 minutes to golden bird. Again, sims first. He graphed heat penetration, avoiding the Darwin Awards.
How Goble Bent NASA’s Supercomputing Arc
NASA Glenn wasn’t playing. Post-Apollo, they chased reusable wings, hypersonics. Goble’s crew ported ARC3D codes to vector machines, slashing sim times from weeks to days.
Why care? Because this birthed modern CFD tools — ANSYS, Fluent — that devs now wrap in Docker for edge sims. Goble’s era forced architectural shifts: from scalar FORTRAN slogs to parallel bliss on Crays.
And the human side — brutal. Tape mounts took hours; one bad reel, and you’re debugging ghosts. Goble thrived there, tweaking solvers till convergence.
Is George Goble’s Legacy Just Physics Party Tricks?
Nah. Peek deeper.
His popcorn saga? Not random. NASA potlucks, sure, but he scaled it: popped 3 pounds in 85 seconds, kernel physics modeled. It’s the ‘how’ of HPC adoption — make it relatable, prove the stack.
Prediction: In AI’s gold rush, we’ll need more Gobles. LLMs fabricate; Goble validated. As edge AI hits drones, expect sim-first engineers calling BS on vaporware.
Tributes poured in. Ex-colleagues on LinkedIn (yeah, he had one) mourn the mentor who demo’d why FORTRAN beats BASIC for real math.
Quiet exit for a loud impact. No fanfare, just wiki and HN glow.
