ClamdestineBoyster posted:I mean it’s almost as if there are 3 ground state dimensions and 3 arc state virtual dimensions that are constantly resolving to the same state through a 7D acidic time cypher, and that inertia is actually just the virtual electron state making a convergent azimuth to a point of resolution in the middle of the galaxy through empty vertical space and the resistance in the circuit that makes for the ground state proton to catch up with the virtual state, or the dreamed or imagined free will of movement making real information state changes in measurable inertial bodies. And that the speed of light (or gravitational mass) and the passage of time are relative. Can you get me a good deal on marzel vanes?

oohhboy posted:They redefined the kilogram so it is now tied to a fundamental element of physics, the speed of light of which they are also deriving other forms on measurements from. It means no matter where you are you can create the kilogram the same as anywhere else. Atomic clocks are the most stable way we can measure time. Internet time is derived from atomic clocks making your PC/phone way more accurate than you think. You can also derive really accurate time from any GPS signal which requires ground stations to correct for relativity. Consumer GPS is so accurate it can place you within a couple meters. Just don't use it in the vertical as it is pretty fuzzy in comparison. The clocks in sattalites run differently to correct for relativity. That's baked in. The ground stations are DGPS (differential) they correct for atmospheric conditions or anything else that throws the signals off. Nothing to do with reletivity. The stations have a GPS antenna positioned to the meter + 6 decimal points. It reads the signal identifies that today at this moment we are off x distance in y direction. It then sends out a VHF signal with a couple hundred mile range. If your boat is equipped with DGPS you are now accurate down to inches. These stations are ONLY near major shipping ports and you phones or handheld GPS may not get it or you probably aren't near one of the sites if you are camping or hiking. They are for boats. And honestly with modern off the shelf GPS receivers unnecessary, if you are going to crash your ship. A 5 meter error down to a .5 meter error wont make a difference. GPS is super old tech.

DrPossum posted:https://en.wikipedia.org/wiki/SI_base_unit Is the problem you have with these definitions that they’re not round numbers? The real mistake was using the second in SI at all. It’s supposed to be a division on the day, but days are slowly lengthening as Earth’s rotation slows. As of 2018, the day contains somewhat more than 24×60×60 (86400) seconds.

MrYenko posted:WAAS is very similar to this, though perhaps not quite as precise, but more widely available. GPS sats move. Waas are geostationary orbit and basically a replacement for the old rear end GPS. Good GPS receivers are also Waas receivers. So yeah. If you buy something make sure its waas for futureproofing.

But using bags like that for collecting air samples is something that is done. Had a friend that was involved with the BP oil spill clean up that would have to do this and take them back to the lab for analysis.

The earlier post of the Navy guy stuck in the engine cylinder reminded me of this oldie. The story of a guy who got locked in a cargo ship engine and was cooked to death. http://maritimeaccident.org/library2/the-case-of-the-one-way-assassin-2/  Another similar case was this guy who got cooked in a plastic mold oven. https://www.theguardian.com/uk-news/2015/jan/12/kayak-firm-pyranha-mouldings-guilty-corporate-manslaughter-oven-death-alan-catterall quote:When the maintenance work had been completed the oven was switched back on and put into warm-up mode by a colleague who was engaged to Catterall’s daughter. A few minutes later smoke was seen coming from the oven and when operators opened the door to find the source of the smoke they discovered Catterall’s body inside. He was pronounced dead at the scene. Can you imagine how it must feel for those last few minutes as you hear the machine powering up? Before the searing pain sets in. gently caress everything about crawling inside big machines like these. My own father crawls into thermal oxidizers from time to time to repair fire proof bricks and he complains that some of the younger guys won't do it. I don't blame them.

Swaying buildings gently caress me up. Like during the last big earthquake in Japan there were those videos of the Tokyo skyline just wobbling back and forth, something like upwards to 2 meters of movement on the top floors. It's great they are designed to be able to do that, but I don't like it.

Gunshow Poophole posted:It feels suboptimal as well poo poo is super disorienting when you're inside It took me more than a decade to get used to that in my building (12 stories + ground floor). Gentle swaying when the onshore breeze kicks in ? It gets filtered out. The wind has to start howling into the kitchen before I close windows anymore. Anything less than a 4.5 earthquake just doesn't register.

I think that depends on a lot of factors, actually, like what the resonance frequency for that mass and shape of water would be. Specifically designed tubs of water are placed in the tops of large buildings to dampen swaying like that.

We had a dude die a couple months ago by climbing into a press to do some maintenance during a scheduled shutdown without turning the drat thing off much less locking it out. He got turned into human paste when he got a bit too close to the wrong photo eye and the machine decided he was ready to be pressed. Broke every safety rule and killed himself to try and save 5 minutes.
