Fun fact : this isn't the first time that imperfection is actually better. I don't know if it's true, but there's a story about the Japanese Shinkansen and how it couldn't reach French TGV speed without tearing its catenary (the cable that sits above electric train lines). They sent some engineers to France to study how we did it, there weren't many differences until one engineer pointed out that our catenaries weren't built with perfect spacing, whereas Japanese precision made them space each pole at the exact same distance, increasing the resonance effect when a high-speed train goes through until it tore down the catenary. So, French clumsiness actually is not a defect but a necessary part of the design. "It's a feature".

Actually, both trains have the same top speed: 300 KPH. The Shinkansen gets the crown as the fastest train in the world because it spends more time at its top speed compared to the TGV. The Shinkansen is also an Electric Multiple Unit (EMU), meaning the electric motors are distributed throughout the train, instead of being clustered under the locomotive and adjoining passenger car axle, which the TGV does. This gives the Shinkansen a higher acceleration rate than the TGV.

Same thing happened to Rolls-Royce when they began building their own GM Hydra-Matic transmissions under license. They hand-polished the internal components' surfaces of the first ones and wondered why they drove horribly, it turns out GM wasn't doing that just because they couldn't put that amount of hand work into a Pontiac at its' price, they were doing it because certain surfaces needed a rough finish for the fluid dynamics to work right.

This happened to a customer I had.. They had a very specific production process that allowed them to make parts better than their competators. They were bought out and as they were winding down production and transfering everything to the new owners, they realized they had run out of a key component that they used for making these parts. They also realized that they had nothing written down about how to make it. There was one machinist still there and they found out he knew how it was made. They asked him to make some and he said"sure". They then asked him to write down the process and he said"no". The company that bought them was also a customer of mine. Last time I visited he was still coming in on a contract basis and making that material for them.

To be fair to them this wasn't really a documentation problem. This was an overuse of classification problem. The knowledge was so heavily classified so it was illegals to properly document it. It was only years later that they noticed it was so classified they accidently didn't keep an unclassified copy of the records. Nobody "forgot" to write the documentation. Everyone just thought someone with a different security clearance had it written down. Everyone was told not to make documentation for security purposes. And if they asked who had it written down they were probably told that someone else they couldn't know the name of had it covered. Just a circle of everyone thinking someone else was the "trusted one" to write things down. And because it was so classified you can't really speak up and ask around to find out who's job it was to keep the unclassified record.

The Bureau of Ordinance also refused to acknowledge the issues in the Mk 14 and claimed that the sailors were using it wrong, while also having their experts get corrected on the torpedo’s use by said sailors. (They also tried to get any sailor who modified the torpedos so that they actually worked court martialed, the naval command was quite unhappy with BuOrd at this point though, so they didn’t)

It might not be better objectively. The with the impurities gone it might be possible to make a more efficient variant. However a different variant would require alterations down the line to the process of creating nuclear weapons. And the US would have to test those new form of nuclear weapons in order to add them to the arsenal. In the current political climate of the world it would be a really bad idea for the US to announce they plan on doing a bunch of new nuclear bomb tests. So instead of upgrading or improving any part of the process the scientists were ordered to replicate the work that had already been tested. In order to avoid having to do live explosion tests they were ordered to attempt to precisely recreate past work, so they could rely on past tests. There is every chance that those scientists could have improved the weapons. However they were ordered to recreate exact replicas of the past weapons to avoid upsetting the world order by the US testing new nukes.

​@@MUrules2014 I think so. But I also think we should continue developing the roads. A good system has the best roads AND the best trains. The roads are already really good, but introducing trains should actually make them better. Then, we can further improve the roads based on how the trains helped them. The trains really work best in cities and connecting cities. However, they tend to get a bit tricky in lower density areas. They work, but the roads really hold up well in these low density conditions. So, I think we should use the trains to supplement the existing system, not to compete with or replace it. Using toll roads, we limit the number of cars entering cities. This should help limit the cars in the city to just the ones that are supposed to be there. Anybody driving to work or from one point to another in the city is supposed to be there. Somebody just passing through the city should take another route. So, to accommodate that, we shall upgrade existing highways that bypass cities to proper freeway standards and build new ones as necessary. The freeways shall be modified to allow overhead railroads to be built over them. The roads are already clear strips of land that connect cities, so they sound like perfect places to put railroads. High-speed passenger trains will be run on these new rails, and the existing railroad network will be just for freight. In each city we can run light rail over the urban freeways, and these intercity trains over the primary arteries. Because freeways and railroads will follow each other, rail interchanges can be placed at highway interchanges, allowing intercity travelers to switch to light rail in the city. The light rail will run over the urban freeways and have stops at each exit or wherever is practical. From there, street cars could be used on large streets within the cities. Ultimately, the way to make roads more efficient is to minimize traffic. Traffic is chaos. Large trucks are necessary for the last leg of the delivery process, but they tend to be problematic in traffic. Truck routes help ease this problem, but cars can usually still go on the truck routes. Trucks just have to take them. I think we should build truck-only highways within cities. The trucks will be separated from the regular cars, hopefully making it easier for travelers. The trucks, in addition, will not have to deal with the chaos of cars coming into or leaving the city as much as before. From a more practical standpoint, I think stacked highways are probably going to be useful. Essentially, we run a bridge deck over an existing freeway, allowing us to expand the road quickly and without needing more land. We take out the median on the bottom and run either direction on just one level. Each level would effectively add however many lanes are on the ground.

Combine this with bad management, no money to do the job right which means it’s rushed, and other manufacturers your working also having the same problem. Suddenly you have 20 people all looking for now somethin was made 8 years ago and no one remembers. Then you spend so much time trying to figure it out you get chewed out at your superiors for not figuring it because they already did it how hard could it be. All the while no one else was able to figure it out either so their just placing blame on the workers lower down for not doing their job when they didn’t have the right people doing it in the first place 8 years ago.

No. Fogbank is not Styrofoam. At least one H bomb from the 50s used polyurethane foam as the interstage material. I've seen no evidence of Styrofoam ever being used. Fogbank is likely rather different. There's indication that beryllium oxide is used in the interstage of the W76 (which uses fogbank). Whether that means fogbank is some form of BeO such as beryllia aerogel, or whether BeO and fogbank are two different materials used in the W76 interstage is hard to tell. There's also come confusion as to whether interstage material and channel filler are synonymous terms. SeaBreeze, the predecessor to Fogbank, which was used in the B61 was chemically related to Diallyl phthalate.

Interesting thread. Conceptually, it is just a filler like styrofoam, but the exact formula made it a particularly 'clean' bomb. The bomb would fission successfully with tonnes of different fillers, but they knew there is a danger of a lot more 'dirt' with an untested filler.

It is factually incorrect to say we know how Greek fire was made.

Here's another --- we manufactured armored vehicles. The drive wheel of a tank is called a sprocket (roughly the size of a washing machine and solid steel). They are wildly tough since they have to propel and brake very heavy tracked vehicles. One year-end our supplier replaced their heat treat bath. Picture a small swimming pool. And it had been in service since the start of the Cold War. The sandy-salty material had been contaminated with countless layers of ambient dirt, dust, cigarettes, half-eaten lunches, paint, piss, hydraulic oil, birds that got too close, spit, etc. Picture chemical witches' brew. Especially since the production parts often had various chemicals on them before they were dropped in. To upgrade the process they removed it and replaced it with industry standard material. Guess what? They sent us a run of parts. Snap-crackle-pop is not what you want to hear the first time you start moving a tank. Took weeks of engineering trial and error to tweak the heat-treat bath. After three weeks of no useful production they removed the new materials and dumped the haz-mat containers of witches' brew back in. Worked like a charm.

The biggest secret, poorly kept is that "it's just ketchup, mustard and mayo mixed together".

there is a similar case regarding the imperfection mentioned here. The holes in the swiss cheese stopped occurring and they were unsure why. But later found out it was due to there no longer being any particles in the milk. The particles were from sawdust and other stuff occurring in farms, and these particles would add the holes in the cheese. Thus to create the holes again they added sawdust themselves during the cheese making process.

The stuff also has one or two materials that could be worth creating a superfund hazmat site if not handled properly in large quantities. Rumors one part of the process is something where they use a fluorine compound, and if you know how reactive or toxic that can be in some cases - it's normally not worth messing around with. (In a way some scientists were wanting to forget about it? Hoping it was a one-and-done thing due to the mess involved in making it, not considering that some aerogels will turn brittle/crumbly over time.)

Time after time he has found that critical “corporate knowledge” has been “lost” usually by firing “surplus old employees”. In some instances he has had to hire back old employees, usually at much higher pay. Sometimes he couldn’t find the old employee or rediscover the knowledge. In some instances he found the old employees had been fired, gone out to work for competitors or started their own businesses and thrived. He still does the same job, now days one of his first steps is to find all employees who have been “let go” in the last 2 years and do a proper exit interview, he says it gives him a comprehensive overview of the business much faster.

The issue now would be idiocy like not having any person with SCI access to all the pieces or losing track of some if those documents, because the only thing more incompetent than the US government you see is some of the parts you don’t.

Like modern software development. Some guy has the "grand picture", and hundreds of programmers work on separate pieces of code. Everyone uses work products from someone else but doesn't know how these were made or what they actually do. And most contributors are not even part of the project and are probably unaware of what their work is being used for. At least there's often documentation nowadays, even if it's all over the place. Ah, yes. "Documentations is like sex. If it's good, it's very very good. If it's bad, it's still better than none." But back to the military, because they have additional "special issues". Even with a pretty high security clearance, it's still all on "need to know" basis. If you work on "process W", you don't need to now about "process V" and "process X". As the manager, you just know that the processes exist, not any details. There is no single person who could leak the complete process. Documentation may be stored in different facilities, where no one knows what the documents are about. Some day, a few decades later, someone might open a safe to find documentation for "process W". One of possibly hundreds of different processes with the generic cover name "process W" (like "K-Stoff"). The documents are marked to belong to a department which no longer exists. Usually, the safe gets closed again and no one the wiser. Arguably, this works very well to keep information from falling into enemy hands. It also is very effective against your own people. But, in typical military paranoia, everyone's the enemy anyway.

Obtaining and purifying the materials is the limiting factor -- separating u-235 from u-237 at the required scale is basically impossible to accomplish undetected. Thermonuclear and implosion fission bombs are too complicated for the high school lab.
