Pretty neat, but the difficulty kinda drops when you realize that just about anyone probably knows what time each section represents just from memory of a regular clock alone.

I would consider this the same as a clock that has no numbers on it, you just know from memory where they are. And really, they couldn`t just put "9" there for itself?

the last part of 7:00 that says .9 with a line over it should actually say 9/9 because there is no such thing as .9 infinitely repeating, that would be 9/9 which is, of course, 1

im pretty sure 9:00 is; root 9 of 9 to the 9th power, not square root of 9 squared, since nothing but 9s are used, it would be kinda stupid if 9:00 had 2s included...

This clock is stupid. I like the one in my school`s math department office. Instead of numbers, it tells you how many radians the hand is at. So, for example, 12:00 is pi/2, 3:00 = 0, 6:00 = 3pi/2, and 9:00 = pi

FYI, this is an offering from the Triple Nine Society, a high-IQ society whose criterion for membership is a score at or above the 99.9th percentile on a standardized IQ test. (Mensa criterion is the 98th percentile.)

Notice that each hour is represented by exactly 3 occurrences of the number 9 with different mathematical operators to make the expression equal to the hour.

If you want to buy a clock like this, you can get one here.

>mystery Are you seriously saying that you learnt "!" in elementary school? Sure, I stumbled on it and figured it out, but we ain`t never used in in class during elementary.

The square root of nine can actually be either positive three or negative three. To make the equations correct, you`d have to take the absolute value of the square root of nine, or you could take the cubed root of 27 instead. Otherwise, this clock would only really work for Schrodinger.

Actually - at 3,4 and 5 o`clock the square roots are fine as they are written. This is because time is considered to be positive and if these particular square roots are negative three the time would be negative as well and that`s insane! <3

"this is more like a "I get math and you don`t" kind of invention."

Not really, it`s like basic middle school math. The square root of nine + nine - nine? If you can`t figure that out, there`s a bigger problem than the clock.

Want - still not as cool as my friend`s radian clock. That thing starts at the right at 2pi and goes counterclockwise, and the fractions of the circle are marked off in radian measure. Also the pi is tyedye...

- Oh come on, does even 9 o`clock have to be THAT complicated?
Ah well, I guess thats why it`s a nerds clock

.9999999~ is EXACTLY 1; it is equal to one if you were to write to infinity decimal places

Thank you.

sloppy notation, young man. -1. :-)

<<sucks at math

No, it comes out as 6.999999999... which is the exact same value as 7.

But there is.

1/3 + 2/3 = 1

.3333~ + .6666~ = 1

.999~ = 1

Or, you know, we could have used logic and worked out that it is a normal 12 hour clock?

(9/9)^9

No, 5 is right. sqrt(9) is 3, 3 factorial is 6, 6-1 is 5.

I bet Cirno would like it too, if she could understand it.

Actually, Gax, it looks like the 9th root of nine to the ninth power, but you still get the same effect.

No, it`s not retarded. Three nines must be involved. All the time.

I`d like to see your dog eat that.

she`s 16 and still has trouble reading analog clocks

.999... is exactly equal to 1.

-,-" I created an account just to reply on this comment. How geek is that? (Btw, I`d buy that clock xD)

The epicness of this is beyond comprehension.

2/3=0.66666.....

3/3=0.99999.....

Thanks :D

It is the "Triple Nine Society" clock. All of the equations on this clock are made up using three nines.

Not really, it`s like basic middle school math. The square root of nine + nine - nine? If you can`t figure that out, there`s a bigger problem than the clock.

it needs more colors or something attractive tho
