minus-square@bstixlinkEnglish104•2 months agoEasy. Take a wire that is exactly 1 meter long. Form a circle from the wire. The circumference of that circle is 1 meter.
minus-square@funkless_eck@sh.itjust.workslinkfedilinkEnglish16•2 months ago “exactly” uh huh. and how are you measuring that?
minus-square@lemmyman@lemmy.worldlinkfedilinkEnglish29•2 months agoNow the engineers and/or scientists are crying
minus-square@Incandemon@lemmy.calinkfedilinkEnglish4•2 months agoScientists maybe, engineering is all about calling things close enough.
minus-square@HopFlop@discuss.tchncs.delinkfedilinkEnglish17•2 months agoYou don’t need to, it’s defined. (Lol). If you take a circle with a circumference of 1, then its circumference will be 1… I think I might have lost some braincells reading this.
minus-square@Kill_John_Lennon@lemmy.worldlinkfedilinkEnglish3•2 months agoHe obviously meant to say how do you measure that it’s exactly 1m, even when still in a straight line. Exactly being the key word here.
minus-square@hesdeadjim@lemmy.worldlinkfedilinkEnglish2•2 months agoBut is the circumference of the outer circle or inner circle 1m? The wire has a nonzero width.
minus-square@Blue_Morpho@lemmy.worldlinkfedilinkEnglish13•2 months agoI don’t have to measure it. I stick under glass and define it as the standard which all other measurements are derived from.
minus-square@RampantParanoia2365@lemmy.worldlinkfedilinkEnglish3•2 months agoExactly. Use a laser measure to cut a plank, then use that for reference!

And this why you don’t touch the thermostat.

I will be measuring it in meters. One. There you go.
Ok, you got another source of water - physicists.
