And even if it wasn't they'd have been hosed if decimal time actually went through, what with the whole 100k second day making the decimal second about 14% shorter.

If they weren't such cowards they'd change the circumference of the earth to match the meter.

Yeah but that’s a relitivistic measurement because there is distortion if you move towards the poles or the tropics, because the earth is a virtual cardioid shape that is being pulled taught into a sphere. So really the best standard ruler would be something that measures the entire magnetic spectrum and that atomically distorts at different locations on earth but is a certain quantum number of atoms long. So a metal where the atoms actually magnetically distort depending on location is actually more accurate than a magnetically shielded alloy at a mean location.

Cojawfee posted:This is the part of the "very special episode" where everyone hears a big crash and they run over to find the old hand crawling out of the crane wreckage. Everyone asks what happened and he says "I don't know, I guess that load was just too heavy. I thought I had it under control." Then the whippersnapper with the college degree says "This is why we have load charts. If you had just learned how to use it, this would have never happened." I always thought it'd be sweet to be acrane operator, cause when I was a kid I liked that kind of poo poo, not to mention them bitches clock mad $krilla. But then I realize the huge amount of responsibility that comes with that and I'm all like, nah, I'm good.

Asproigerosis posted:Don't worry, this same poo poo happens in health care. The American Registry of Radiologic Technologists has started doing a halfassed Maintenance of Certification test for all certifications after 2011. We have to take an 'ungraded' board exam on areas that we least encounter in our day to day practice every 10 years. The problem is that they grandfathered all techs that got their certifications before 2011, so they don't have do it. These are the people that are most likely to be uneducated in a lot of areas of current practice standards. They're the ones that learned how to do xrays in a hospital basement from a nun 30 years ago. People that only ever had formal training on emulsion film (something that was effectively replaced universally with computed/digital radiography in the 00's). People that don't know what a pixel is and pretty much just survive on rote memorization from what buttons the applications person told them to push. You know, the people that clearly don't need to prove they are up to date on current practice standards because they have ~experience~. It is incredibly frustrating trying to interact with some coworkers in MRI because they learned how to do it in 1993 and that's how we've always done it so no we're not changing anything. I guess there will always be a place for button pushers. This reminds me of a story about a patient who got a seriously damaging dose of radiation from a clueless X-ray tech because they didn't understand how the machine or display worked and just kept hitting the buttons over and over and repeatedly dosing them.

The therac was a different issue; by mashing the controls in just the wrong way you could get it to switch to its high-power beam and forget to move the target block into the beampath. The software interlock was the sole interlock preventing this, and the fault was not discovered in testing. So, operators had no reason to doubt that the machine was configured correctly, and the effects on the patient wouldn't point to it all that directly.

Technically those are fire whirls, they're like dust devils. A tornado occurs when a super cell thunderstorm (mesocyclone) drops to the ground. Incidentally, fire storms can cause super cell thunderstorms consisting of pyrocumulonimbus clouds, and there is at least one recorded instance of one producing a tornado. This occurred in Australia because of course it did. https://en.wikipedia.org/wiki/Fire_whirl https://en.wikipedia.org/wiki/2003_Canberra_bushfires#Canberra_Fire_Tornado

The middle supports sank.  Before. Both sets of blue supports are the same height above the water.  After. One set is much lower than the other. They don't know why, but say "something under the riverbed failed". Yep.
