  • Paul Campbell,

    well seconds USED to be 1/86400 of a day and then 1/31557600 of a year - but days and years aren't that regular (which is why we just got a new leap second this NYE). Now that a second is the base units for our (MKS) measuring system, we can't keep changing it just because the world's rotation is running down

    Precisely.

    Yes, but my point is, if you're going to a decimal system, then surely the base unit should be a decimal of something, not a 1/31557600.

    Why? A metre is not a decimal of anything. A gram neither.

  • Paul Campbell,

    by making the second the base unit we can keep our years (and days) synchronised to the sun by dropping in the occasional leap second (and leap day of course) - in the distant futire as I've pointed out we wont care about the sun (or we'll have different suns and planets with their own numbers to worry about)

  • JackElder,

    Didn't we just add a leap second this year? I used mine to take a short, but well-deserved, break.

    So... who's going to see that new Star Trek movie then?

    Like that wonderful hard-working My Key. :)

    A gram was. It was the weight of a cubic cm of pure water or something like that.

    And a litre is a decimal portion of a cubic metre or something. And a litre of water is almost exactly one kg (depends on where it's measured and its temperature).

    Sure, but then... what's a centimetre? At least one of those units is going be a tenth of nothing at all.

    Isn't that what the Large Hadron Collider is for measuring? :)

  • Paul Campbell,

    leap second? I got a whole leap DAY - on which I was required to work for free! (Like many people I'm paid the same monthly salary whether there's a leap day or not)

    I think that leap day (or the closest Monday) should be a public holiday

    Thought you said that was System's goal?

    Yes, but it's a decimal of nothing at all. Not at 60th, 24th, or 365thand a bit-th.

    Why would you change the system of time and leave in three different factors, none of which is 10?

    Dude, the links between the two would blow your freakin' mind.

    But I've said too much already ...

  • Kyle Matthews,

    What I mean is - days, and years, make sense. They're not decimal, but they relate to the world around us.

    Hours, minutes, seconds, arbitrary numbers someone picked out of their arse. Why would it be the second that you'd keep for your number base? Why not the day or the year? Standardise it at a certain date and ignore the fact that it changes in minuscule ways.

    Nobody is changing the system of time, and coordinated universal time (which is not metric) is never going to become part of the everyday conversation on earth, although it's useful in some very specific fields.

    It's just that at some point scientists wanted a more precise, constant definition of the key units of measure - to standardise experiments, amongst other things - and so they came up with the atomic clock which measures the second the way it does, and to the definition of metre we've discussed. Not to have to go to Paris and measure against the official metre every time, you understand.

    (of course you can't ignore minuscule changes in most modern scientific experiments)

  • Keir Leslie,

    Look, when they got in metres and everything, they tried dicking around with the calendar, and nobody went for it.

    As a rule, if Napoleon couldn't do it, it is a Bad Idea.

    (See also land wars in Asia.)

    Caesar managed, though. Just sayin'.

    Reckon. So if System weren't still in beta, the LHC might still be working? (imagine that said like a Scooby Doo ending)

    See upstream where Paul suggested kS and mS. So, if you were changing the system of time, why wouldn't you change your base so that it worked on earth as a decimal was my point.
