You can’t measure the cesium frequency without having other units defined.

Wrong if you’re a photon. No time will pass as you cross the universe
It’s not useful to tell somebody it is constant without a way to make use of it. Without knowing how it’s defined relative to other things we can’t use it.
The thing about all the absolute physical constants is that they are almost all based on units defined relative to other things. Unitless constants (defined only as a ratio) are extremely rare (like the fine structure constant) - but even then you have to make up units to measure them (although you can still agree on unitless values with somebody else who chose different base units for measurements).
https://en.wikipedia.org/wiki/Dimensionless_physical_constant
Every metric of speed of light is necessarily relative to other things. Even if you define as 1, now you must be able to know what one unit of time is relative to one unit of distance, and if you do not know that then you do not know that your speed of 1 means.
All fundamental units are defined relative to each other in physics, and all other units are defined relative to the fundamental units.
https://en.wikipedia.org/wiki/SI_base_unit

Everything in physics is defined by relative properties. Scale all fundamental units by the same factor and we can not detect any change in behavior whatsoever

Technology@lemmy.world•ONLYOFFICE accuses "Euro-Office" maker Nextcloud and IONOS of License ViolationEnglish
2·2 days agoYes, a creator can create a closed source copy (independent of the GPL’d work), assuming they have full ownership or permission from all contributors
It’s not fully academic only because it’s common for companies to develop a GPL version and offer commercial licenses where the corporate customer is exempt
But none of this affect the users of the GPL version, so most people don’t care

14·2 days agoYou can’t call it GPL3 and at the same time claim the copyright.
Weil you can (because you still own the copyright after giving your work that license), but you have given a legally binding promise to not impose additional restrictions so it won’t do you any good to try

16·7 days agoHere in Sweden you can list with and without, since businesses can buy without VAT (technically they get to subtract the VAT on purchases from their tax bill) so shops which have businesses clients tend to do both while regular shops only list it with VAT

The biggest clue to that bombing is them admitting they asked AI for targets and it delivered outdated info


For somebody who claims to be acutely aware, you really seem to have no idea what goes into calibrating measurement devices to be able to measure physical constants. In particular you have no idea how many other units go into calibrating them, and how you fundamentally can not get an accurate reading of a physical constant without that calibration. And for somebody claiming I’m the condescending one, you’re awfully rude yourself
Just see the definition of the kilogram, and how it’s now defined in relation to time, c, and the planck constant.
https://en.wikipedia.org/wiki/Caesium_standard
Everything meaningful is defined as relative properties, as ratios to other forces and properties of nature.
