Number Patterns

I think patterns on clocks and odometers are really cool. 11:11 seems to feel significant to me on the clock. I like watching patterns on odometers too - I look for a full house or a run. I actually watched my car, brought my camera that day, and pulled over to take a picture when my previous car reached 123456.7 miles. Silly? sure. but fun.

My car's mileage hit 111,111 at 1:11pm last month... The only palindrome I tend to notice is 2112.

I tend to notice patterns in letters too, and i have a tendency to group letters in a word into equal parts...and if bugs me when they don't divide evenly. apparently I need more to do...

I went through a time of about a month when I constantly saw the sequences 123 and 923 every time I saw a number. I think my mind was just playing tricks.
*Lorax: Oh yeah, I once wrote a check for $222.22 on Feb 22. I noticed the funny coincidence and then looked at the check number. 222! It kinda freaked me out.

One of the ones I notice a lot is years. When my purchase totals, say "18.72," I'll occasionally say something like "A good year," which seems to totally baffle people.

I always notice combos of '8's and '4's for some reason...and I love it when I see the number '808' on a digital readout, since it spells my first name ('808' on a digital clock sorta looks like BOB)

since you included numerically significant numbers -- what about historically significant numbers? (1776, 1812, etc.) steve: What were classes 18.02 and 5.60 and why were they so horrible? (Does everyone else know this?)

2^n or 2^n-1 always catches my eye, for any n < 16 or so.

Although I don't gamble, I have played video poker on my computer, & I tend to notice full houses & straights more than anything else.

Then there are the results of the old calculator games, like 55378008 (the punch line of a long calculator joke about Dolly Parton's mastectomy).

*** elijahblue - good point, I forgot about dates.

*** bill - a while back the high bit of the Unix time went to one, which meant it's now a negative number if you treat it as signed...

*** elijahblue - 18.02 is 2nd term calculus (which I took first term at the same time as 8.012 [physics for masochists], which consistently introduced new calculus ideas two weeks before 18.02 did), I think 5.60's a chemistry course.

Having gone to MIT, there are many numbers that were courses. When the .01g balance here at work reads 18.02 or 5.60 I just cringe.
***5.60 was Chemical Thermodynamics, and it was just difficult and boring and I took it during a term when I had too much else to do. 18.02 is multivariable calculus, a fundamental freshmen requirement that all MIT students are required to pass to graduate, and I seem to be constitutionally incapable of multiple integration. I took that damned course THREE TIMES, and I got a C the third time I took it, and I STILL failed the final; I'd just gotten so good at vector algebra and partial differentiation by that point that it all averaged out to a C.

2^n numbers: 1024, 2048, 65536, 32768... Too many years lost in front of a computer...

steve -- heck, at least you had company...

It's a joke that the clock is always at 11:11. Pretty bizarre actually ... but I'm sure it's just because I always notice when it is.

if it's (for example) 2:35 , I'll see 2+3 = 5

in addition to powers of 10 I notice large powers of 2, and certain powers of 5 and 6.

Sometimes I see numbers transposed. Seeing 79 miles as 97 miles can make for amusing trips.

kabbalistic?
I do factors and multiples, like 3:36 or 2468 or 7:14:28. Also, I see "lucky numbers" like 23, 79 and 37 a lot. In 1990, there was a moment when the date/time was 12:34:56 7/8/90, and I saw it coming, noted it, and told some friends.
Recently the Unix time_t number which is how Unix stores internal date/times as "seconds since 1970", crested 900 million, I noticed it coming but missed the actual moment.
Obsessive compulsives love this stuff.
* Oh, I also do mirror-image numbers like 1251.
Romkey, I think the high bit is not yet set on time_t's (they are 32 bit integers right?) That should happen 2147483648 seconds after 1970 or sometime in 2015. Perhaps we could have a party then...
** I thought of another, squares. (e.g. 9:16:25)

actually I just look at double digits. like 20193451 would look like 20 19 34 51 to me....helps memorizations.

I don't really understand the question. I'm dense sometimes.

all sorts of numbers!
