@BernieSanders Bernie, none of those you mention work for Elon Musk. You should be promoting Musk and his companies and jobs if you want to lift them out of poverty.

You are correct. Marie Curie died from aplastic anemia, but which particular of her many radiation exposures caused it wasn’t determined. Her husband didn’t live long enough to die from it, but it was inevitable considering the amount of radium he worked with. Alpha radiation can’t penetrate the skin, but internally it is one of the worst. I once owned a radium dial pocket watch that read 2 mrem on contact with the dial. It would leave a red patch on the skin inside the watch pocket, which is why I disposed of it. Thank you for correcting the myth about the husband’s death, an item I should have researched.

@theMRC Does that mean ChatGPT has reached the intellectual capacity of a young liberal?

Thermodynamics is the science that bootstrapped the Industrial Revolution. The man hours it took to develop the Molliere Diagram and steam tables, invent the concept of entropy, and develop all the measuring tools to dissect the properties of H2O are astronomical. Sad that so many fail to understand it in the modern world. Fortunately the builders of satellites like The Nancy Grace Roman Telescope do understand how to transfer heat in a vacuum or none of the instruments or computers would work.

@Kaeos108 @BuzzPatterson Military rules: you can want anything, but what you will get is what the military thinks it needs, and fits your skills. That’s why recruiters’ promises mean nothing.

@BuzzPatterson A cheat to defeat a design feature.

Enough knowledge to recognize when independent advice is needed. For example an airframe manufacturer should not ignore warnings about a flawed certification procedure from employees who realize shortcuts are paid for in blood. In the nuclear industry and others, it’s called a safety culture.

[Jack Mohr @SOP00067]

The safety analysis required for building a nuclear plant specifies the maximum credible earthquake for the location.
The fuel pool and other components are designed to survive the quake intact. Instruments monitor seismic events and require inspections following significant events.

@BuzzPatterson You have to give Canadians credit for all the extremely hard work they put in to find and elect a clown worse than Trudeau. Truly epic shot in the foot.

[Jack Mohr @SOP00067]

@ScottAdamsSays There was much discussion of the legality of random drug testing at the time. But after implementation industrial safety made a step change for the better. Hard to argue with results.

@WallStreetMav What are the chances of a judge being impeached if it takes a 2/3 majority of the senate to impeach them, when the Senate cannot even pass voting reform that meets the world standard with a Republican majority in the Senate?

This appears to be an apology for the tornado warning we had a few minutes ago

@TRobinsonNewEra Victims and survivors of the rape gangs should be included in this remembrance, loudly.

Per Grok:

No, Ship 40 (Starship from Flight 13) is not in Australia yet.
It soft-splashed down intact in the Indian Ocean on July 24, 2026 (the first Starship upper stage to survive tip-over without breaking up or sinking quickly). SpaceX dispatched recovery vessels (including GO Australis, Normand Ranger, and Skimmer Tide) and began an attempt to tow it toward a Western Australian port such as Dampier.
Progress has been slow (often ~1–3 knots) due to the vehicle’s size, lack of proper towing points, currents, and weather. By early August the convoy was still hundreds of nautical miles offshore. Elon Musk noted around August 7 that recovery was “not looking good” amid high seas and winds, though teams had already collected valuable close-up imagery of the heat shield and engines.
As of the most recent tracking updates (around August 13–15, 2026), Ship 40 remained afloat (near the Christmas Island region), towing was paused or intermittent due to conditions, and support vessels were still operating around it. There has been no confirmed arrival in an Australian port.
The situation is fluid—weather and sea state will decide whether a full tow to shore succeeds or the vehicle is eventually scuttled after further inspection.

@pinstripedline Compare it to the Narwhal?

@JohnCleese Perhaps the Monarch has been too influenced by corrupt advisors. He’s too isolated from the real world.

The Okavango Delta’s surface water (channels & swamps) is freshwater — surprisingly low salinity (~40-80 mg/L TDS, EC often <200 µS/cm). Despite 95%+ evaporating in this endorheic system, it doesn’t turn saline.
Solutes get “sunk” into island groundwater & precipitated out, keeping the wetlands fresh for its amazing wildlife. A hydrological marvel! 🌊🐘

Current high efficiency jet engines are a hybrid,with the propeller a ducted fan at the engine inlet, boosting the jet turbine horsepower by increasing the air inlet density and using the dense cold air bypassing the turbine to increase thrust efficiency. Plus armored intake for blade failure. The propfan engineers had an almost good idea.
