This. Same... 😅

The second division of the hour.

Decimal time exists, thanks to the French Revolution.

There are 100 decimal seconds in a decimal minute, 100 minutes in a decimal hour, and 10 hours in a decimal day. Each second is slightly shorter than a SI second.

Unfortunately, there is no easy way to decimalise time for human use. If you make it useful for humans, it doesn't sync well to a day. If you make it sync to a day, the resulting units are awkward for the human mind.

Amusingly, for computers, time is decimalised! UTC is a fully metric time. It's just simpler to constantly remap to and from UTC to a user's time, than to train the user to use UTC.

I actually quite like this idea. Or we could start using number base 12 instead of 10 everywhere else.

It'll likely happen once we move to living mostly in space (if we survive that long ofc)

They linked the kilogram to the gravitational force.

It's part of an effort to clarify how we define things. We're now trying to link our recorded units to the basic forces they are related to. So now, the kilogram is defined by the gravitational force, the meter by how fast light travels, etc etc

I misread that as "meat ball", and now I'm kind of disappointed that we don't use meatballs as a standard unit. "I'm 6 meatball subs and 3 balls high", "The yacht is about 18 giant party subs long", etc.

Not exactly. The kilogram was redefined in a fundamentally different way, moving from an artifact, which will change with time, to a fundamental property of nature, that as far as anyone knows, will be the same at all times. The second was already defined in such a way. Any such definition still requires some sort of measurement though to get something usable. Different ways of measuring the same type of definition can be more precise, and in this redefinition they think they've found a more precise method that works in the same fundamental manner. Both measure the oscillation rate of atoms, but the proposed element is thought to give better precision.

Could you be more specific?

Most likely indirectly, like how GPS has to account for satellites not matching the passage of time on earth due to relatively.

You can now be more accurately late for work. Or your coffee is more accurately taking a long time to come out.

Relativistically.

If they can predict earthquakes and eruptions more accurately, as suggested in the article, then yes for all the people who don’t die.

I better not have to buy a new watch because of this.
