Glass is technically (ie, it's atomic structure is that of) a supercooled liquid but exhibits all the characteristics of a solid because it's a glass and they do that.

Also on the subject of tempered glass: https://www.youtube.com/watch?v=6V2eCFsDkK0.

There are Prince Ruperts drops. Because of how things cool in water (the outside cools super fuckin quick and the inside cools hella slow) you get natural tempering in the globs of glass you drop into it. Because of this, you can run the bulbs of them over with a fuckin steamroller and it will give no fucks, but if you snap the tiny tail on it then all the stresses get released explosively because they no longer balance out. Cool stuff.

Bill Bryson should be obsolete and failed (I've only ever read the first ten pages of one of his books and every page had at least one "I can't be arsed to check facts" sort of glaring error).

It's almost like he's a travel journalist writing books for a mainstream audience with the priority of being engaging over being scientifically rigorous. I've reread Short History a number of times and he specifically apologizes in advance for any errors he makes, and says directly that it's his fault for misunderstanding or misrepresenting them rather than the fault of any of the experts he spoke to or otherwise cited.

If you think that any book that contains any factually wrong scientific information should be burned or banned, or is automatically drivel - that doesn't leave a whole lot of books left. Bryson isn't writing textbooks and he isn't pretending to.

In terms of obsolete and failed technology, has anyone had any experiences with Wireless USB? I remember hearing news about it in the tech blogs a few years back, but I've never in-person seen a product using it, or really heard anything about it since.

Looks like it's still doing fine, and people are making products for it, but it seems to occupy the same niche that bluetooth does. Bluetooth already does this pretty adequately for anything besides super-high-speed applications, and is much farther down the line in terms of adoption rates.

The health issue with uranium cookware, or uranium anything really, isn't so much that uranium is radioactive, but rather that uranium is poisonous like lead is.

If you decided to just start eating uranium you'd die from uranium poisoning well before you'd get any meaningful dose of radiation.

Sorry to quote from a few pages back but I'm a nuclear nerd and had to jump in on the uranium discussion. "Fresh" Uranium (stuff that hasn't been in a reactor) is just barely radioactive since the half-life of U-238 (aka depleted Uranium) is about 4,500,000,000 years and U-235 (stuff used in nuclear fuel) is 704,000,000 years. Plus these isotopes decay through alpha emission and alpha particles can only travel about an inch in air and won't penetrate skin. In fact, when we get new nuclear fuel bundles delivered at work you can safely stand right next to them with no shielding and it won't even register on our dosimeters.

I was going to say the same thing. I was lucky enough to get a tour of the control room (well, a room next to the control room with a window looking at the control room anyway) of the nuclear power plant in Rochester, NY before 9/11 basically made it so you can't get within 200 feet of any of the cool parts of a plant without being detained for questioning.

You might be interested in visiting your local nuclear power plant when they open up on their community information night.

I got to play with the simulator control room of the Columbia Generating Station as part of a job boondoggle a few years ago. The operator put everything in operating condition and asked us to try and make the reactor scram (without manipulating rods). I think I disabled the backup movement mechanism for the control rods and it scrammed.

I once got to go inside the facility at Texas A&M university. Most people don't know they have a small nuclear reactor on campus. It was a little anticlimactic, it's a very small reactor and most of the building is empty space -- it just looks like what you'd think a reactor would look like on the outside.

However, they did show us the open tank of water the core was submerged in. Then they turned it on while we watched. You couldn't even tell it was on except for the fact that there was a blue light down at the bottom of the pool where the reactor was. Cherenkov radiation is extremely beautiful and I'm one of the few people who's ever seen it in person.

Tens if not hundreds of thousands of people have seen Cerenkov radiation in person. For example, every nuclear scientist, and every person who's ever worked around an immersion research reactor, like that at Texas A&M and hundreds of other universities worldwide. What you saw was basically standard operating procedure -- as long as you have that twenty feet of water between you and the reactor core it's perfectly safe.

Now, if you'd seen Cerenkov radiation in the air, instead of in a protective water pool, you're pretty special. If you saw Cerenkov radiation in air more than a week ago, and you're still alive to talk about it, you may be the only one on the planet.

I read somewhere that "scram" is actually an acronym for "safety control rod axe man". In the earliest reactors built in the 1930s, the safety mechanism was literally a bunch of control rods hanging from ropes above the reactor, and if something went awry there was a dedicated axe-man who would chop the main rope and cause the rods to drop into place, halting the reaction. I know that that is indeed how the first reactors' control rods operated, but I don't know if that's actually why they use the term "scram".

And a lot of times when you have control systems around for decades they might upgrade the computers, but not the interfaces. I visited the Titan Missile Museum in Tucson once, an old early ICBM bunker.



Lots of controls, and when the places was built in the early 1960s all of those cabinets were full of electronics. Ten or fifteen years later the computer systems all got overhauled with new stuff, which did the same functions while only filling a couple of racks in there. Had the whole site not been shut down as part of 1980s modernization programs they probably would have put in some tiny board, but still wired it to all the same controls.

I also got this stuff there:



Old canned water from civil defense programs. It's really not that different from a lot of beer cans of the era, I gather, and might have come off the same bottling lines as such. Before there were even pull tabs and you needed to punch an opening with a churchkey opener.

I don't remember those days, but I do remember this era:



Pull tabs that ended up tossed on the ground where you could cut bare feet, flat-sided steel or bimetal cans. And brown 7-Up labels, I don't even remember that. It looks so foreign now that I'm used to sculpted aluminum with stay-tabs. By the way, I heard stay-tabs took literal years of design and experimentation before commercial adoption. Not that they're that complicated in principle, but they needed to make them with a minimum of materials and with a basically zero failure rate to not upset customers. The cans have also gotten thinner and lighter over the years, for related cost-savings reasons. When you make millions of something, every gram shaved off by better designs and manufacturing processes saves money. Remember these 2-liter bottles?



Specifically the separate opaque plastic bottom. 1970s-80s manufacturing processes weren't up to making a single piece bottom that both would stand up stably and not crack or break under pressure when treated as roughly as people treat plastic bottles. Once they got that working right, they ditched the base and 25% of the plastic needed. Plastic caps came along later, and still more recently they moved toward shorter caps that use even less materials. Modern bottles have a lot of performance margin too. They're tested to take 100psi, and they're durable enough to take dozens of reuses and repressurizations if you do homemade soda or something.

Also, remember 10 and 16 ounce glass bottles with styrofoam labels, before they got around to making single-serving plastic bottles?

Yes, I love the march of packaging technology. Well, other than the ones that increase shelf life at the expense of making things drat hard to open. And I mourn the obsolete technology of instant-win contests that don't require you to go to the company website and register to enter the number on the cap.

I remember reading about a fatal accident at an irradiation facility, where the worker realized something was wrong when he walked in the chamber to free a stuck mechanism, and there wasn't that cheery blue glow deep down in the pool. Instead he was standing right next to a bunch of cobalt-60.

Hanford does offer tours, but you have to sign up within an hour or two of when they make the slots available. When I visited in April, they let us go into the original ("B") reactor and look around. Here is a picture from the control room that seems appropriate:

It's taken a lot of abuse, but has a lot of solid metal parts and is pretty heavy. It's the World War II-era furniture of the off-brand video game controller world.

Never could figure out what that little slider thing in the bottom middle was for, though.



The N64 "Expansion-Pak" added a whole 4 megabytes to your console's processing power.

This is the control room for the first production reactor in Sweden, Ågestaverket. It was built as a research reactor, but also provided heat and electricity to the Stockholm area.

When it was mothballed in 1974, all radioactive material was removed, but the plant itself was left intact. Very few people are allowed in to see it, but I hope it will be turned into a museum some day.

I know that that is indeed how the first reactors' control rods operated, but I don't know if that's actually why they use the term "scram".

At Penn State we used to "pulse" our research reactor and produce a huge flash of Cherenkov radiation. To pulse the reactor we would run it at about 10 watts then fire the central control rod out with compressed air, the power would spike to about 1,000 mega watts then drop back down to baseline in a few milliseconds. It was always a good day when you got to see that.

SCRAM does in fact mean safety control rod axe man and SCRAMing a reactor means it was shut down by dropping all of the control rods in as fast as possible. It's the official term for that situation, even the NRC uses it in their reports. It's one of the few nuclear engineering jokes out there. My favorite is the unit of cross-section for neutron absorption is called a "barn" since hitting a U-235 nucleus with a neutron is like hitting the broad side of a barn. So it makes sense that a microbarn is called an "outhouse" and a 10^-24 barns is called a "shed."

And I mourn the obsolete technology of instant-win contests that don't require you to go to the company website and register to enter the number on the cap.

My grandfather actually was one of the R&D scientists at Continental Can Company, and he worked directly on both of those projects. The current five-prong shape of soda bottle bottoms came from his group - he hired a sculptor to make the shape attractive once they figured out how to manufacture a solid-enough bottom.

It really was the work of years, too. When my mother was in college and law school, now and then she'd mention on the phone that some new soda bottle designs had hit the shelves, and my grandfather always had her send them some for competition research. Then the bottles would arrive all exploded, and his team would basically say "Well, that's clearly not it," and get back to work.

Earlier in his career, at Monsanto, he was on one of the R&D guys focusing on the original productization of plastics, including coating the inside of cans to prevent rust. Until my idiot uncle threw them out after my grandparents died, we had some memento pop-beads, which were the original shipping and storage unit for plastic before it was melted and molded for use.

My grandfather was a real nerd-type inventor; he often got frustrated when corporate would react to an invention with a "We can't sell that." For example: a one-at-a-time cracker dispenser. Most crackers would crumble to pieces being run through those screw threads, but who cares? It's a simple and elegant way to accomplish something almost nobody wants: getting only one cracker at a time straight out of the package. :science:

He still worked in retirement, and one of the neater jobs was consulting on making a zero-G fire extinguisher for high-altitude planes and spacecraft. The big problem was that water-sprayers would aerosolize in freefall and fail to smother the fire.

The solution came to him when he shaved one morning and really paid attention to his shaving cream. Oh, pressurized foam! :downs:

He died of end-stage emphasyma. Don't smoke, kids.

I read somewhere that "scram" is actually an acronym for "safety control rod axe man". In the earliest reactors built in the 1930s, the safety mechanism was literally a bunch of control rods hanging from ropes above the reactor, and if something went awry there was a dedicated axe-man who would chop the main rope and cause the rods to drop into place, halting the reaction. I know that that is indeed how the first reactors' control rods operated, but I don't know if that's actually why they use the term "scram".
That and others like Super Critical Reactor Axe Man are backronyms. Sounds like it would have been fun to talk about around the lab, though

:) I heard you're on the Chicago Pile team, what do you do?
:black101: If something goes wrong, I stop the reactor with an axe.

Same company, pretty similar build. This one's actually bigger than the SNES itself and has a metal bottom plate. I still use mine on my PC with a Super Smartjoy(SNES to USB adapter). Still a great stick for fighting games, and the layout is ambiguous enough to work for both SNK and Capcom-style fighters.

I put two thigh shaped rust spots on the metal base plate of mine. Wore a groove into the stick too. Still works perfectly.

Pull tabs that ended up tossed on the ground where you could cut bare feet, flat-sided steel or bimetal cans. And brown 7-Up labels, I don't even remember that. It looks so foreign now that I'm used to sculpted aluminum with stay-tabs.

I swear when I first scrolled past this image, I thought these were those old "dancing" soda cans you could get back in like the late 80s and early 90s. The top looks just like the pull tab tops here, which was odd since those types of tabs weren't in use when we actually bought the dancing cans.

Lots of toys danced for a few years. We had that can, a big dancing Kool-Aid character, but in my kid-mind THESE were the original:

Hanford does offer tours, but you have to sign up within an hour or two of when they make the slots available. When I visited in April, they let us go into the original ("B") reactor and look around. Here is a picture from the control room that seems appropriate:



The best part is peeking around the control panels and seeing thousands of wires coming out of every switch and display.

The Hanford tours only show you plutonium production reactors which were designed in the early 1940's. I was talking specifically about the commercial nuclear power plant on the edge of the Hanford reservation, the Columbia Generating Station. The control rooms are quite different. B-reactor was the first ever "big" reactor and not just a pile in a field. The reactor core was a huge block of graphite with holes cut in it for the uranium rods. Average length of time in the core: about one month.
And how would they eject rods from the core? It would be a guy with a long rod pushing into the rod channel from one side of the reactor so that the desired spent fuel rod would fall out the other side into a water basin.
The rods would spend some time in there to let the short lived radionuclides decay. Then they were loaded on open trolleys and carted a few miles through the desert to one of the gigantic processing canyon plants.
The history and engineering of that place is simply fascinating. I have worked there off and on for ten years.
Fun fact: the reactors had open loop cooling. River water from the Columbia would enter the reactor core for a single pass, then spend a few hours in open air cooling basins, and then be discharged right back into the river. At the heyday of production, Hanford plants released approximately 14,000 curies of activity into the river each day. It's mind-boggling.

Also: of over a dozen Hanford nuclear reactors, only one produced electric power. The others were single purpose plutonium production reactors that discharged their waste heat into river water.

Same here. Had one as a kid, and bought one a couple of months ago as part of my retro collecting binge. It really is built like a tank, and a great stick, even if fighting game enthusiasts sometimes complain about the L / R button positions [the gray buttons] since the buttons aren't in two rows of three like a normal arcade stick.

Now then, its daddy:



This thing is indestructible. I should know - I had one as a kid, and was prone to gettin' mad at video games. This thing took all the pounding I gave it and kept on truckin'. It's a truly great stick.

Also, I totally love the style of both sticks.

Correct me if I'm wrong here, but aren't these for disaster relief and they only churn them out as needed? I remember Anheuser Busch gave a poo poo ton of water to the 2004 tsunami relief.

What advantage does a can have over a plastic bottle in that situation? Just curious.

I actually cracked the plastic on my NES advantage around the joystick from pushing right too hard. Still works fine.

The fact that their plants are already set up to churn them out by the millions.

E: Also easier to ship half way across the world in bulk.
