Work decided a while back we had too many near misses so they showed the supervisors and engineers a bunch of videos of people dying in big machines. I didn't react much because I think I've seen all of them here first. Note they didn't decide to show the actual workers who are nearly killing themselves, for no good reason.

chitoryu12 posted:You’d be surprised and terrified by how many crane operators (especially outside the United States) don’t really know the exact weight of what they’re lifting or how to not tip the crane. 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.

It's always funny to watch the building stuff shows and to be able to spot the hastily issued, never used eye and ear protection that people put on when they realize they're on camera or have a producer issue them. At least those guys aren't faking it like everyone else does.

The metre ought to be one ten‐millionth of the distance between the equator and the North Pole along the meridian passing through Paris, at sea level. That was the original intention. The platinum–iridium artefact is off by one part in five thousand (or eight kilometres over the circumference of the Earth). Even that small difference was too much to ignore after the error was discovered. It would have ruined too many measurements referenced to the marks on the rod that are slightly too close together.

It was 1796 and they hadn't actually taken a boat far enough north to know for sure how long the Paris meridian really was yet. By the time said boat came back the "meter of the archives" had too much institutional inertia to bother changing. ok actually they mostly spent 6 months measuring a 10 mile stretch of road in Spain with a set of platinum yard sticks and taking measurements on a fancy new surveying device calibrated in a brand new decimal system of angle measurement because EVERYTHING was going to be decimalized. dis astranagant fucked around with this message at 08:20 on Sep 18, 2018 |

The surveyors’ measurements were good but their understanding of the Earth’s shape was imperfect. More importantly, the politicians didn’t wait for the surveyors to finish. They just started using the provisional metre.

if it was done by the french, who ever "did" it was jerking himself off while someone who can't read actually carried out the measurements and reported to a separate, semi-literate underling.

I like how they were going to base the definition on the length of a pendulum with a half‐period of one second but then someone took a boat to South America noticed that Earth’s pull was feebler there.
