Sagebrush posted:You are thinking of the ATLAS-I electromagnetic pulse testing facility, which simulated the EMP effect of a nuclear blast on aircraft systems without having to set off a nuclear weapon. Thank you for this! I do some material science overlap work (technically I'm in mechanics, but with my specific projects there's plenty of overlap) on polymers, and this is fascinating! I'm tempted to send it to the chemist on the project and ask how he feels about working with radiation. Should be good for a laugh, anyway.

thing that everyone thinks. Rather, Lockwood is pine wood that is soaked in methyl methacrylate (plexiglass, lucite) monomers, then put into the nuclear reactor to polymerize it into a wood-plastic composite. The unique advantage of triggering the polymerization with radiation is that you can penetrate deeply inside the material and ensure it's completely cured all the way through. Less-dangerous radiation like UV light can't penetrate the wood, and triggering the reaction chemically before soaking won't give you enough time to fully saturate the wood before it cures.

The stream just went to break (it's a local news stream, but it's just a live stream of the firefighting when it's on) but before it did it looked like they were dropping on the island? Presumably they think it's worth trying to save something, or at least put it out so salvage can begin sooner. There was also a small but noticeable list. There's another stream linked below, but it's, uh, a little foggy right now and you can't see anything. https://www.youtube.com/watch?v=y0DhWEB01rk

Platystemon posted:I am reminded of a cool tug. That article has a LOT of good OSHA bits. quote:In mid-March, when the volume began to approach that amount, curiosity got the best of Raphael G. Kazmann, author of a book called “Modern Hydrology” and professor of civil engineering at Louisiana State University. Kazmann got into his car, crossed the Mississippi on the high bridge at Baton Rouge, and made his way north to Old River. He parked, got out, and began to walk the structure. An extremely low percentage of its five hundred and sixty-six feet eradicated his curiosity. “That whole miserable structure was vibrating,” he recalled in 1986, adding that he had felt as if he were standing on a platform at a small rural train station when “a fully loaded freight goes through.” Kazmann opted not to wait for the caboose. “I thought, This thing weighs two hundred thousand tons. When two hundred thousand tons vibrates like this, this is no place for R. G. Kazmann. I got into my car, turned around, and got the hell out of there. I was just a professor—and, thank God, not responsible.” quote:Up the valley somewhere, during the ’27 high water, was a railroad bridge with a train sitting on it loaded with coal. The train had been put there because its weight might help keep the bridge in place, but the bridge, vibrating in the floodwater, produced so much friction that the coal in the gondolas caught fire. Soon the bridge, the train, and the glowing coal fell into the water.

It's been a surprise to me to find out how many dangerous animals are just big loving dogs when they're not trying to kill you. For example, I was talking to one of the rhino keepers last time I went to the zoo. Now rhinos in general aren't as dangerous as people think; they mostly only charge and murder people when they're scared. But, it turns out, rhinos that have been in contact with humans (like their keepers) long enough to get to know them are really like big dogs - to the point that on chilly days when the rhino wasn't allowed out into the outside exhibit, he would wait at the gate for the keepers to arrive and try to get them to play with him all day while they did their job. The keeper even made the "big dog" comparison himself, saying it was like trying to do work at home while your dog wants your attention. tl;dr: rhinos are bros

It's very light weight; we used to have a few bars of it in a lab I worked in and I'd play with them while I was bored. It can also be quite strong if you use the right processing, though obviously not on the level of steel and such. It's probably my favorite metal. Yes I have a favorite metal shut up

The various attempts at building a suitable reactor for a jet turbine are a wild story just by themselves. I don't have my books to go into all the detail, but the short version is that stripping a nuclear reactor down to bare essentials, removing unnecessary things like "shielding" and 'liquid coolant," doesn't really work.

Anyone have good recommendations for good OSHA books, preferably those that do a deep dive and analysis of a single industrial accident or wreck? I prefer the type that puts it in a historical context rather than just technical descriptions of what went wrong. Books on similar topics I've liked in the past are Tom's River, Tragedy at Honda, and so on. The more obscure, the better, as long as the writing of the book is sufficiently well researched.

I went on a train wreck kick for a bit, and The Day the Whistles Cried: The Great Cornfield Meet at Dutchman's Curve: The Story of America's Deadliest Train Wreck as a very good historical account of an obscure disaster, as is Lost at Thaxton: The Dramatic True Story of Virginia's Forgotten Train Wreck.

That train has engines from 3 different companies leading. I wonder how much more of a pain in the rear end that made all the cleanup and insurance paperwork? Obviously only one company is going to be operating the train, but they're going to have borrowed the power from the other two companies, which has to make things more complicated.

Potato Salad posted:going to go out on the limb to suggest that maybe a bullet-sized californium bomb would not compress and thus burn very efficiently Extreme crystal phases are really neat. I don't know much - they're only tangentially related to my field - but then, nobody knows much. That's kind of the point. Prediction of phase changes from first principles is just good enough that we can sometimes guess where to look, and not much use after that. And, of course, the problem with phases that only occur under extreme pressure/temperature conditions or are of short lived materials is that they're very hard to study, because they vanish so quickly. There is a push to look for metastable phases, and I believe even some predicted possibilities, but I don't recall seeing any literature on actual successes yet.

CitizenKain posted:One guy flew by a IJN ship and shot at them with his sidearm. In the Battle off Samar, there are accounts of pilots running out of ammo after strafing IJN ships continuing to make dry runs, because anything they could do to slow down damage control or distract AA fire away from planes with ammo bought that much more time for the surprised escort fleet to escape. Similarly, torpedo planes made multiple dry runs for the same reason. That same battle also had the only gun duel between warships won by a carrier, when the escort carrier White Plains scored a 5-inch gun hit on the Chokai, detonating her oxygen torpedos, crippling her, and leaving her vulnerable to later airstrikes. However, while the White Plains is generally credited with the hit, there is some ambiguity as the Chokai's logs claimed the immobilizing damage came from a bomb strike.
