The Future of Leap Seconds

@10u8 writes "Since 1972 precision clocks around the world have ticked using atomic seconds, but earth rotation is slowing down. Leap seconds have been inserted in order to keep noon happening at noon, but they upset some timekeepers. Recent discussions have considered discontinuing leap seconds in UTC, and a colloquium in Torino next month will present results. It is a matter of international significance."

    I propose we keep the earth spinning at a constant rate by detonating thousands of nukes at certain places once every four years. This will produce a Catherine Wheel effect and the earth will speed back to its original spin rate.

    Asshats from the Industrial Revolution days make us do a frickin' "leap hour" twice a year anyways, one of which violates causality. Fuckin' Daylight Savings Time.

    What drooling asshat decided that it'd be a good idea if, every year, there was one day when everyone's heart/respiration rates slowed down to one beat/breath per hour, and about six months later, these same people should be able to start a 20 minute download that finishes 40 minutes before it started?

    It seems to me that we should get rid of the concept of seconds altogether. The second was devised in the Sumerian culture, along with such bizarre ideas as a circle having 360 degrees.

    The French of course stole the concept of decimalization from Thomas Jefferson and applied it to a variety of measurements, but failed to carry it to a good conclusion by decimalizing time (it seems everything French starts off well but is never really completed).

    It seems to me that real progress should be made by dividing the day up into decimal units of time, and the circle into decimal units of arc, thus eliminating the second as a unit of measure.

    OK, so the clock people don't want to have to calculate when leap seconds have or will happen when figuring out the time from A to B. And they also want noon to happen when the sun is highest in the sky, and summer to happen on June 20/21.

    There is a simple solution:

    Build a pair of giant rocket to control the rotational speed of the earth. Then just give it a 'kick' every now and then to do stuff like countering tidal drag and such. You could even get rid of leap years if they were powerful enough!!
    NASA isn't even using its last Saturn Vs anyway.... Might as well put them to good use. Or, if that's not enough, we have like 10,000 nukes ready to go.

      America is to blame! We are only 5% of the Earth's population, but we use 80% of the angular momentum.

      It's the failure of the world's industrialized nations to use renewable power sources. By drilling for oil, millions of tons of heavy crude are removed from the the depths of the earth and brought to ground level. Since angular momentum is conserved, the earth's rotation slows slightly to compensate for the now-larger moment of inertia. Extraction of metals from mines also contributes to the problem.

      Granted, we have in part compensated by dumping large amounts of waste into deep parts of the ocean, and cutting down trees--but it's not enough! We need to begin a massive campaign to raze the forests and dump mercury and lead into oceanic trenches. Hopefully, we will one day be able to restore the Earth's rotation.
