Tuesday, May 04, 2010 9:39:21 PM I've learned more about math in this thread than my Algebra, Geometry, Algebra II and PreCalculus classes combined. That was a lie. I never took Algebra.

Monday, May 03, 2010 9:37:41 AM It's 120!/(2!3!) with 5*Sum_{n=0}^{inf} 2^{i}, pretty early huh?

Monday, May 03, 2010 12:51:42 AM Frig me gently, I had no idea we had so many resident math nerds here at IAB. And many unfamiliar users who stay quiet through the standardfare religious, political and ideological flame wars, but who come out gunning at the first hint of a bit of math. Don't get me wrong, I'm not poking fun, I love this. IAB is a complex community, with many undercurrents and subcultures...

Monday, May 03, 2010 12:31:48 AM Technically, this clock isn't only for geeks. Yes, they are the ones who'd get a kick out of it, but you would have to be a complete idiot not to know which numbers the equations translate to.

Sunday, May 02, 2010 8:27:01 PM Are you people *still* debating the 0.999... = 1 thing?

Sunday, May 02, 2010 8:24:51 PM 2 is an infinite sum. We got them all. Very cool clock. I would pay money for this...

Sunday, May 02, 2010 8:20:00 PM @ trashcan 7 2 is just summation notation for the infinite geometric sum of 1/2

Sunday, May 02, 2010 5:29:31 PM If you're still wondering what they are, look up in the more comments: page 1 should still have my posts where they're all explained in detail (it's 3 posts).

Sunday, May 02, 2010 5:28:09 PM Lionhart explaining the clock: "Here: 1. Legendre's Constant 2. ??? 3. Unicode HTML 4. Modular arithmetic 5. Golden Mean 6. Factorial 3 7. 6.99999... 8. Binary (1x2^3 + 0x2^2 + 0x2^1 + 0x2^0) 9. Base4 (like Binary is Base 2 and Hex is Base 16, this is Base 4 numbering) 10. Binomial Coefficient 11. Hexadecimal 12. Cube root=inverse of 12^3 No idea on number 2."

Sunday, May 02, 2010 5:19:51 PM yanging... even those who disagree that .999...=1 would disagree with your statement. Do you know what .99... means? It means that the 9 is repeating infinitely. You can't say .99... *10= 9.90; that's completely ignoring what the proof is telling you. Anyways, I can't believe you don't believe that .99... is not 1. You can't look at it differently; that's the beauty of math: it's straightup true or not. Wiki If you are still arguing this, try taking a basic calculus course and then come talk.

Sunday, May 02, 2010 5:08:57 PM I'm in Alg. II and I get 10...? And an easier way to get it wouldn't be 120/6*2 Just do 5*4/2*1 (since you can cancel the 3*2*1)

Sunday, May 02, 2010 4:49:03 PM @Fatninja01, 3!, does not equal 6! at all. 3!=3*2*1=6 6!=6*5*so on and so forth.

Sunday, May 02, 2010 4:36:40 PM "Ikeray: this proof works better. X=0.99... 10X=9.99... 10XX=9 9X=9 X=1=0.99..." problem with this is that .99 x 10 is 9.90, not 9.99

Sunday, May 02, 2010 4:14:13 PM i still dont get 1 3 10 and 11.. D: but then again i've only taken advanced algebra. still :/ i am saddened by this

Sunday, May 02, 2010 4:05:35 PM @tozhan I don't really think that proof is valid. You need to show why 10XX=9. The person who doesn't understand that .999... = 1 won't really understand that the decimal portion of 10X equals the decimal portion of X.

Sunday, May 02, 2010 10:07:17 AM I have no idea what these mean, but I can still figure out what time it is. Does that make me a super genius?

Sunday, May 02, 2010 9:51:46 AM mluther, the 1/3, 2/3, 3/3 isn't as good an explanation as .111...=1/9, .888...=8/9, .999...=9/9=1

Sunday, May 02, 2010 9:41:17 AM they should have used eulers identity for 1... that won is way cooler.
