Want: Part III

submit to reddit

Via Astropixie comes this item of win:

But it doesn’t say how I can get one!

And how would 1984 open? “It was a bright cold day in April, and the clocks were striking 9 + root(9) + 9/9.” Not quite the same ring to it.

    Hey! The clock says it’s time for 9 beers!

  5. 5.   JackC Says:

    Feh. It isn’t a sqrt(9) * 9 – sqrt(9) hour clock. Who needs it?

  6. 6.   alfaniner Says:

    Do I want one?

    Nein!

  7. 7.   alfaniner Says:

    Actually – maybe I do want one — I love unusual clocks. But the joke didn’t work the other way…

  8. 8.   SonOfSLJ Says:

    I would have phrased the joke something like…

    “Can I live without one?

    Nein!”
    :)

    You need to express 13 using only three ‘9’s. Can it be done?

  10. 10.   Michelle Says:

    that is so GEEK!

    I want it! (what’s the triple nine society?)

  11. 11.   Fergus Gallagher Says:

    13 = 9 + sqrt(9) + .9 bar

    D’oh! Oh course. I gotta get that.

  14. 14.   The Centipede Says:

    I think I’ve confused my coworkers enough with my binary clocks.

  15. 15.   Cameron Says:

    I just need to figure out how to replicate the cool design in the center. Then it’s not too hard to print out a clock face and replace an old one.

  16. 16.   MarshallDog Says:

    There’s a glare… does 1 o’clock say (9/9) to the 9th power?
    And does anyone know how to prove .9 bar is equal to 1?

  17. 17.   Chris R. Says:

    Why do analog clocks even have numbers? Are they afraid people will forget how to tell time on them? :P

  18. 18.   Phy Says:

    Chris R. – but if you don’t have numbers on an analog clock, how will you know when you’ve hung it upside down? ;)

  19. 19.   Fergus Gallagher Says:

    @MarshallDog

    (’ = bar)

    x=.9′
    10x – x = 9.9′ – 0.9′ = 9
    => x=1

    OR

    1/3 = .3′
    3 * .3′ = 3 * 1/3 = 1
    but 3 * .3′ = 0.9′
    => 0.9′ = 1

  20. 20.   Fergus Gallagher Says:

    @Chris R

    - I guess you don’t have have young children to try to teach to tell the time, then!

  21. 21.   Barton Paul Levenson Says:

    This clock gets a failing grade. It fails to reduce the expressions to the simplest possible terms.

  22. 22.   Evolving Squid Says:

    Lawyers need clocks too.

  23. 23.   The Centipede Says:

    > Why do analog clocks even have numbers? Are they afraid people will forget how to tell time on them?

    There are 12-hour analog clocks, 24-hour analog clocks, probably various other X-hour analog clocks for specific purposes, so on and so forth…

  24. 24.   ZZMike Says:

    OK, OK, I’m entranced by the none-ness of the thing, but ….

    … why 9?

    They could have used any other single-digit integer (though “1″ would have been pretty pointless).

  26. 26.   Mikhail Bragoria Says:

    pfft… it’s not even a 24 hour clock.

  27. 27.   Murff Says:

    I like the inner design, it would be better without all the 9 crap…

  28. 28.   Sean Says:

    Doesn’t have to be nine. I just worked out a whole clock using a triple 3.
    8 was pretty trippy. Any other numbers?

  29. 29.   Moose Says:

    Oh, that’s slick. I want one.

  30. 30.   Lugosi Says:

    is there any particular significance to the symbol in the center. Reminds of something from the TV series Threshold a couple of years ago.

  31. 31.   Tim G Says:

    Suggested Remaining Hours for a 24 Hour Clock:

    9+9 – 9!/9
    9 + 9!/9
    9! / sqrt(9) OR 9 + sqrt(9)!
    9! / sqrt(9) + 9/9 OR 9 + sqrt(9)! + 9/9
    9+9 – 9/9
    9+9
    9+9 + 9/9
    ( 9 – sqrt(9) )! – 9/9
    ( 9 – sqrt(9) )!
    ( 9 – sqrt(9) )! + 9/9
    9! / sqrt(9) + 9

  32. 32.   MandyDax Says:

    @Tim G
    It’s a triple-nine clock. You have to use exactly three nines in the expressions.
    13=9+sqrt(9)+.9bar
    14=9+sqrt(9)!-.9bar
    15=9+9-sqrt(9)
    16=9+sqrt(9)!+.9bar
    17=9+9-.9bar
    18=9/sqrt(9)*sqrt(9)!
    19=9+9+.9bar
    20=?
    21=9+9+sqrt(9)
    22=?
    23=?
    0=9(9-9)

    BTW, 9!=9*8*7*6*5*4*3*2*1=362880

    I couldn’t find solutions for 20, 22, and 23 using three 9’s. I’m sure someone here is smart enough with logic to prove if there are no solutions for them. :P

  33. 33.   Anotherplayaguy Says:

    Has anyone worked out the numbers 1-12 using three sixes?

    If so, I’d like to see it.

    Thanks,

    It’s a reference to the “triple 9 society”, a sort of super-Mensa group where your IQ has to be at or above 99.9% of the general population (roughly 134).

    Do I want one?

    Nein. I want nine! (But not 9!)

    Oops! I just realized that I was thinking of triangular numbers when I was using the factorial (!) symbol.

    Substitute Tn for n!.

  38. 38.   Crudely Wrott Says:

    That’s the miracle of analog devices. You needn’t know the delineations that the hands are passing, you only need to know their relative positions on the dial. That, plus knowing whether it is day or night, tells you the time at a glance.

    That’s why analog (needle) gauges are still predominant in race cars. They are in airplanes too. Even those with glass cockpits display critical indicators such as artificial horizon and rate of climb as digitally simulated analog instruments. They are simply more intuitive and can be understood at a glance even under demanding circumstances.

  39. 39.   Ronan Cunniffe Says:

    1 = F((6+6)/6)
    2 = sqrt(F(6+6))/6
    3 = F(6+6 – F(6))
    4 = 6+6-F(6)
    5 = F(6-(6/6))
    6 = F(6) – F(6/6)
    7 = F(6) – F(6/6)
    8 = F(6) + (6-6)
    9 = F(6) + (6/6)
    10 = F(6) + F(6) – 6
    11 = F(6) + (F(F(6)) mod 6)
    12 = F(6+6)
    13 = F(6+(6/6))

    I started trying to finish Evolving Squid’s solution, but things rapidly multiplied out of control… 11 gave me serious paws for thought.

    Oops. Some of those got away…

    even though the answers to the equasions are all ready known, how most of those answers pan out I dont know

    Great fun, but seriously, people who own these should not be walking around unsupervised.

  43. 43.   Fergus Gallagher Says:

    20 = floor(sqrt(sqrt(factorial(9))))-sqrt(9)-.9bar
    23 = floor(sqrt(sqrt(factorial(9)))) – 9/9

  44. 44.   Fergus Gallagher Says:

    22 = floor(sqrt(sqrt(gamma(9)))) + 9 – .9bar

    I don’t think “gamma” and “floor” are cheating if “bar” and “factorial” are allowed :-)

  45. 45.   LUke Says:

    Fergus already pointed this out on how 6.999 repeating does equal 7 but the equation here was a little easier for me to understand, so:

    n=0.9 repeating
    10n=9.9 repeating
    10n-n=9
    9n=9
    n=1

    I’ve heard of this, but never seen the proof for it…interesting

    @Luke:

    Write 1/3 as a decimal.
    Multiply by 3.
    Discuss. :-)

    Co-worker had one. Loved it. Bought one for youngest LurchGS replacement’s birthday, and sent one to LurchGS’ immediate paternal progenitor for the end-of-year celebration.

    Sadly, overlooked ordering one for self. Oh well, I can always stop in Youngest’s room for a time check

    I clicked though to the comments on this just to see if there might be a Holy War on the “0.999…. = 1″ issue. I’m happy to see that there isn’t. Maybe because the readership here understands the implication of mathematical proof better than other places on the Internet.

  52. 52.   Shannon Says:

    I want this clock so when you get the information you better tell me!

  53. 53.   Robert Carnegie Says:

    My sister has a backwards clock. The hands run in reverse direction and I think all the figures are mirror images. Besides a good gimmick, it would suit in a traditional barber’s shop.

    I didn’t quite catch in a [30 Rock] episode where the girls were discussing these two guys they might date, one of the guys was shown explaining laboriously he has a watch he is real proud of, that shows the time in pie slices, I think he -may- have meant analogue style… don’t do it, lady! :-)

  54. 54.   Anotherplayaguy Says:

    Ronan,

    Thanks for the input, but I am confused by F(6) which seems to equal 8. Why is that?

    Thanks

    What is the meaning of a time of day that is plus or minus 3:00 o’clock, or any of the other times that involve a square root. For example, the 4:00 spot could also be -2:00, since -3+1=-2.

    Awesome.

  57. 57.   printzen Says:

    A better representation of the number 7 using three nines is: 9/.9 – sqrt(9) = 7 exactly. This avoids any need for discussion about whether .9 recurring is or is not equivalent to 1 (at least in reference to the “3 nines clock”)
