I don’t really own old machines. I just become their caretaker for a while. This old Westinghouse has been keeping things cold for generations. Its freezer is smaller than a loaf of bread, but nobody told it that was supposed to be a problem. #BuiltToLast #Vintage #RetroTech

One of the strangest journeys I’ve taken: Quantum computing lab ➜ sci-fi novel ➜ research paper. A physics idea I couldn’t stop thinking about became my first published independent research paper. DOI: 10.5281/zenodo.20544186 #Science #Engineering #Research #NEMS

The worst heat pump is more efficient than the best gas boiler. A gas boiler turns one unit of energy into less than one unit of heat. A heat pump delivers 3 to 4 units of heat for every unit of input. More in future Substack long read. Sign up here: janrosenow.substack.com

Every time I upload my audiobook to ACX, a different chapter needs another +0.1 dB. Not the same chapter. A different chapter. I’ve stopped calling this audio mastering and started calling it bat appeasement. 🦇🎙️ #Audiobook #BookSky #IndieAutho

A story that started as an idea in my head became a manuscript, then a book, and now an audiobook. It’s almost time to submit Echoes From Orbit to Audible. That feels pretty surreal. 🚀🎙️ #Audiobook #SciFi #IndieAuthor #BookSky #WritingCommuni

1,000 KENP read may not sound huge to some people, but as a first-time indie author it genuinely means a lot to me. People I’ve never met spent real hours reading something I created. That’s kind of incredible when you stop and think about it. #IndieAuthor #BookSky #SciFi #AmWriting

Recording an audiobook feels professional. Editing the audiobook feels like forensic audio analysis conducted by a sleep-deprived raccoon. 🎙️🦝 #Audiobook #WritingCommunity #AmWriting #IndieAuthor #BookSky #AudioEditing

What’s the oldest thing you own that still works perfectly? 👀 #RetroTech #Vintage #Nostalgia #OldButGold #TechTalk #ClassicCars

The hardest part about eating dinner with four dogs isn’t the begging. It’s the overwhelming feeling that they genuinely believe I forgot to serve them their portion of my food. 🍗🐶 #DogsOfBluesky #DogSky #ShihTz

Zoey enjoys basking in the sun where she believes she is a princess, but also thinks she will melt if she goes outside in the rain. #DogsOfBluesky #PomChi #DogSk

Engineering eventually teaches you the difference between: “that’s probably fine” and “that sound is financially significant.” 🔧 #Engineering #HVAC #MechanicLif

Still strange seeing a story that lived entirely in my head for years sitting on Amazon like a real object. Writing a book feels a bit like building a radio and discovering someone answered back. 🚀 #SciFi #BookSky #AmWriting

I daily a 21 year old Chrysler product and I have reached a stage where repairs become less “maintenance” and more “preserving an ancient pact.” Then pray the next electrical failure is something I can live without and not a critical system. #CarSky #MechanicLife #ClassicCars

Harley can hear a plastic bag crinkle from three rooms away… but her own name apparently exists on a different frequency. 🐶 #DogsOfBluesky #ShihTzu #DogSky

Before reentry, the #Artemis II 🚀 crew module separates from the service module. While the service module provided propulsion and power throughout the lunar mission, it cannot survive the return. The crew module continues alone, using its heat shield to protect the astronauts during descent 🌍

The mathematics of the universe suggest we are unlikely to be alone. But the same mathematics may also explain why we may never meet. 🌌 #Space #Astronomy #SciFi #FermiParadox #SETI #Physics #Science #SpaceTwitter

I’ve reached the stage of life where I casually say things like: “I’m submitting my paper on a novel quantum physics concept.” Meanwhile I still occasionally forget why I walked into a room. 😄 #Quantum #Science #Engineering #Confido

Some of the smartest, kindest, most capable people I’ve met will never be famous. None are celebrities. None are billionaires. Maybe we’re looking in the wrong direction. #Confido #Humanity

Mayan culture likened the Orion Nebula to a cosmic fire of creation. It's an enormous cloud of dust and gas with a stellar nursery. At its core are four massive young stars, known as the Trapezium. #astrophotography #astronomy #naturephotography #nature #longexposure #eastcoastkin #photography

Officially, MOL-42 is an orbital research platform. Unofficially… maybe don’t ask what’s under the fairings. ☢️🚀 #SciFi #WritingCommunity #BookSky #IndieAuthor #Space #HardSciFi #ConceptArt #Worldbuilding #EchoesFromOrbit #NASAcore

Captain’s Log, Day 4. I now spend more time programming the FMC than I do managing my actual life. Priorities remain properly aligned. 📟✈️ #flightsim #msfs2024 #aviation

A NASA satellite captured images of the sky sparkling with rare, vibrant colors—greens, pinks, and purples dancing above the Earth as cities glow below 🛰️✨.

Captain’s Log, Day 3. The passengers applauded after landing. Mostly because we survived, but I’m choosing to take the win. ✈️ #flightsimulator #avgeek #VirtualAirline #msfs2024

If you bought my sci-fi novel: 1. Please leave a review, it genuinely helps indie authors survive the algorithm void. 2. If you haven’t bought it yet… that sounds fixable. 🚀 Paperback • Hardcover • Kindle • Kindle Unlimited #scifi #indieauthor #booksky #KindleUnlimited #spaceopera #hardscifi

Captain’s Log, Day 2: Discovered flying the plane is only part of the job. The rest appears to be convincing the autopilot I know what I’m doing. ✈️ #FlightSim #Aviation #AvGeek #MSFS

Be honest… If your pilot said: “Don’t worry, I trained extensively in flight sim” how concerned are you? 😄 #FlightSim #Aviation #AvGeek #MSFS

Captain’s Log, Day 1: Promoted to 737 Captain of my virtual airline. Morale is high. Management remains suspiciously familiar. ✈️ #FlightSim #Aviation #MSFS #CaptainLog

What one sci-fi movie , new or old , would you commit to watching once a month for a year ? #Scifi

Time for my monthly viewing of The Last Starfighter. Just in case the recruiter finally shows up. 🚀 #SciFi #Confido

Friendly reminder: I wrote a book. It escaped into the wild and is now available in paperback, hardcover, and Kindle. No astronauts were harmed in the making… probably. 🚀 #scifi #indieauthor #booksky #kindle #amreading

Who remembers this movie? #moviesky #filmsky

Not quite teleportation… but we’re now moving a photon’s state across open air. Feels like we’re slowly building the infrastructure for the sci-fi version of communication. 🚀 #SciFi #Quantum

Just some #StargateSG1 Action to finish today off folks, I love that SG1 got really cool once the SGC got the F-302 and started to make use of the Prometheus and the series started to move towards more Space Story Arcs once that happened. #Stargate #SG1 #SciFi

I finished the Planes, Trains & Automobiles painting. This is the final piece for my solo exhibition at @quirkyfox.bsky.social. Details to follow. #caricature #art

I keep getting identical “greetings from San Francisco” messages… Starting to think it’s not bots. It’s a coordinated signal.😜 Not sure from who… or why. 🚀 #SciFi #Bluesky

I made a teaser trailer for my book… why not . Echoes From Orbit Now in paperback , hardcover, kindle and kindle unlimited! #Confido #IndieAuthor #BookSky #BookTrailer youtube.com/shorts/ZrU9F...

Scientific mis- and disinformation is among the greatest threats to our society.

Caught Zoey and Fergie being cute after making a mess by dragging half their toys out of the toy box. #DogsOfBluesky

Got asked to autograph my book for the first time today. It was a coworker… but I think that still counts as achieving orbit 🚀 #IndieAuthor #SciFi #BookSky

I work on a team developing the highest efficiency heat pumps able to operate at -20f temperatures. It’s frustrating when people still believe this kind of misinformation.

Truth!

Confido was a word given to my family in 1263. “I Trust” Figured it was time to put it back to work 😄 I use it as … Capability becomes ability when you trust yourself enough to act. Help me make it a thing. #Confido

In a world… where one guy decided to write a sci-fi novel… he actually finished it. Echoes from Orbit is now available on Kindle & Kindle Unlimited. 🚀 (narrator voice sold separately) #SciFi #BookSky #IndieAutho

We also have help ignoring the craziness in the world with 3 little dogs , this is Harley , named after Harley Quinn ( as a puppy she had black fur around her eyes like a mask) . She lives up to the name…

Currently turning my sci-fi novel into an action movie trailer… debating how many times I can say “In a world…” before it becomes a problem. 🎬 Confido and Ad Astra always #SciFi #IndieAuthor #BookTrailer #Filmmaking

NATIONAL LIBRARY WEEK "Hey, Teenagers: Pay close attention to the books people try to ban. Then, make a beeline to read those books, if you can. Find out for yourself why those people want that book banned. Find out for yourself if they can be trusted to know what’s best for you.” ~ Jeff Zentner
