“Raptor 3 is engineering art [@XFreeze] Raptor 3 is engineering black magic SpaceX’s Raptor is the FIRST full-flow staged combustion engine to ever fly - only the 3rd ever built (after the Soviet RD-270 and the 2000s US demo that never flew) → Both fuel-rich + oxidizer-rich preburners → 100% of propellant through”

“Exactly [@kylenabecker] @amyspitalnick We're not saying that Charlottesville itself is a "hoax." We are saying the SPLC allegedly *HELPED* to engineer the conditions for it happening, and then materially aided-and-abetted a Unite the Right organizer and thereby promoted a clash between protesters and”

“Tesla engineering redesigned lithium refining from physics first principles [@tesla_na] Our Lithium Refinery is designed to have a much lower carbon footprint than traditional hard rock refineries – Acid-free refining helps produce a safe coproduct – Water is recycled throughout production, with every drop treated & cleaned on site – Designed to close the loop for”

“Look at the tiny cars in the foreground to get a sense of the vastness of the building [@HalcyonHypnotic] Hot take but SpaceX is probably the best civil engineering company in the world. Somehow they are able to make these insanely complex ground system and building designs and find the perfect contractors and technicians to build out their ideas in months or 1-2 years. I feel like”

“Starship Super Heavy Booster, the most powerful moving object ever made by far [@SpaceX] First 33-engine static fire for Super Heavy V3”

“@Teslaconomics @Tesla_AI Best was working with such a great team of AI hardware & software engineers! It was more fun than going to parties on Saturdays by far.

“@ArthurMacwaters Less thrust than that today, but the long term target is 300 tons of thrust per engine for 10 kilotons of thrust at liftoff or shortly thereafter”

“@NASASpaceflight Look at those beautiful Raptor 3 engines!”

“Yeah [@pmarca] It's incredible the extent to which the social sanctioning engine has simply seized up. Hit pieces that would have been 5-alarm fires 5 years ago now come and go with no notice. Nobody cares, it's over.”

“Try using the X API [@Scobleizer] Met a founding engineer today from @Replit. Jen Li. We were both judging the @Pokee_AI hackathon. They have me some credits and I built two apps in 20 minutes using the X API:a weather one which mapped storms being reported in by my climate scientist list and another monitoring”

“Tragically & hilariously true [@Ne_pas_couvrir] Here’s Ben Stein in 1979 describing television as an engine of cultural demoralization. He argues that a small clique of producers and writers pushed a left-coded inversion of reality onto the public. They despised traditional power centers and hated figures like Buckley. They”

“My idea of a good time is working with amazing engineers to create incredible technology 🤩 The Tesla chip research fab will have all the machines needed to do logic, memory, packing & masks in one building for a lightning fast development cycle. Heaven 💫”

Cybertruck is the only truck in its category to be awarded the highest honor. 🦾 Congrats @Tesla Engineering Teams!”

“RT @WR4NYGov: Engineers in the factory - essential to Elon’s vision. “In a single building, we can create a mask, make the chip, test the…”

“Big difference [@ArthurMacwaters] Most people will probably miss that this chart is log scale Meaning it shows a 10,000X reduction in cost This is quite literally insane. Engineering is magic.”

“No voter ID, especially when combined with mail-in ballots, means the system is engineered to make fraud impossible to prove. Everyone knows that you can barely get through your week without showing ID for the most banal activities, like shopping at Costco. The only reason to [@KatieMiller] The reality is there's mass amounts of cheating in our elections. Just because there's an engineered lack of data, does not mean there isn't data to the contrary. The new CBS/YouGov poll shows that 80% of Americans support Voter ID including 80% of black Americans & 77% of”

While the 10-engine static fire ended early due to a ground-side issue, we saw successful”

“SpaceX is Caesar’s XIII Legion level good [@DeepBlueCrypto] "Somebody I know went to work for SpaceX and said, 'It's like being dropped into a zone of shocking competence.' The best engineers in the world want to work for Elon Musk because he's the one CEO who's able to work with them as a peer."”

“RT @Cernovich: Grok is the search engine that Google used to be. The results are actually what you were looking for, and then some. 10/10.”

“@PeterDiamandis Reminds me of that old joke. AI engineers keep building a better and better AI, asking the same question: “Is there a God?” Eventually, the AI answers: “There is now!””

“@engineers_feed They told me my score was the highest they’d ever seen fwiw”

“lol [@signalapp] These attacks, like all phishing, rely on social engineering. Attackers impersonate trusted contacts or services (such as the non-existent “Signal Support Bot”) to trick victims into handing over their login credentials or other information. To help prevent this, remember that”

“@AtelierMissor_ The ancient Egyptians had an incredible run of ~3000 years. Their æsthetic sensibilities and engineering were outstanding. The Great Pyramid remains a marvel even today! https://t.co/PhlR4ebXUc They always worshipped the Sun as one of the gods, but Akhenaten created the first https://grokipedia.com/page/Great_Pyramid_of_Giza”

“Grok 4.20 is getting good at engineering [@DrPhiltill] Wow. Just used Grok 4.20 beta to brainstorm space program ideas. Note: I've been developing similar programs for many years and have deep intel into this world, but Grok blew me away with fresh, actionable concepts. When ppl say AI can't create new ideas, they're wrong. 1/2”

“@JessePeltan For anything to do with engineering and science for sure, but Imperial has a certain romantic charm for civilian use. I set a more intuitive variant of metric for Starship: tons for force and mass, bar for pressure. It’s easier to do mental math, eg thrust to mass ratio, than”
