You know about numbers, right? Natural numbers, rational numbers, integers, real numbers, complex numbers, prime numbers, funny numbers, illegal numbers. Illegal numbers? Well, there’s the illegal numbers game
. Apparently 69 is illegal in Virginia
, among other places. But did you know about illegal prime numbers
? My brain is getting number by the day. (via digg)

Significance of numbers.
Not to be confused with the concept of "significant figures," this page lists the significance of numbers 0 through 1000.
"2 is the only even prime."
"24 is the largest number divisible by all numbers less than its square root."
"3367 is the smallest number which can be written as the difference of 2 cubes in 3 ways." Whoa!

Not Lost After All
Given recent posts proving
various meanings of the ongoing numbers references on the television program Lost, I figured that some of you would be interested that a person over on Flickr seems to have a much better explanation: they're simply geographic coordinates.

Mentioned in this post
in the context of a "good or evil" algorithm, gematria (גימטריה) is actually Jewish numerology, assigning values to the letters of the Hebrew alphabet and establishing mystical correspondences. It's basic to kabbalistic works like the Zohar
, and you can get detailed analysis here
. But we both know what you really want to do is plug words into a text box and get the result instantly, right? Here you go
. And to start you off, METAFILTER = 299 [מטאילטר] according to the traditional system; according to The Gematria of Nothing
, it's 31. Take your pick.

More on arithmetic in the Amazon
The 10/15 issue of Science has the official publication of Peter Gordon's work on numerical cognition among the Pirahã, and a companion article by Pierre Pica et al. on similar research among another Amazonian tribe, the Mundurukú. What with the U.S. election and the discovery of H. Floresiensis, this is not getting nearly as a much play as the pre-publication back in August of Peter Gordon's work.
Brian Butterworth has an piece
in the Guardian about both articles, and I've put some links, quotes and diagrams here
Compared to the reports on the Pirahã, the Mundurukú people, language, and experiments are all somewhat different, although the conclusions are broadly similar.

Top Ten Favorite Numbers
Conceptual artist Claude Closky's
most recent smart art. Vote for your favorite numbers and, based on popularity, 4 becomes number 1, 7 becomes number 2, etc. They change all the time. Closky did another great piece, published by a book (available from Printed Matter
) whereby he simply organized numbers 1-100 alphabetically, thereby changing their value.

Me Ta Fi L Te R = 318514
The Phonetic Numerals system provides a convenient way to remember long strings of numbers. It's really simple: the system replaces the numbers 0-9 with the symbols
(the strikethoughs indicate the difference between the symbol and the letter that it takes the place of). Take a long number (3.1415926, for example), convert it into Phonetic Numerals
), then come up with a phrase using those letters (
ob.) See? Easy!

"Modern scientists have known about synesthesia
since 1880, when Francis Galton
, a cousin of Charles Darwin
, published a paper in Nature on the phenomenon. But most have brushed it aside as fakery, an artifact of drug use (LSD
can produce similar effects) or a mere curiosity. About four years ago, however, we and others began to uncover brain processes that could account for synesthesia. " This article
from Scientific American seems to be turning heads around the Psychology Department at U of M [Michigan]. It's got me going too.
I've seen real connections between color and sound before, stone sober. Could there be something to all this?

Counting in base-14.
"Just because we
use a decimal system doesn't mean everyone does. "The teseradecimal lifestyle is thus not just a way of life. It is not only a method of regulating marriage, birth, succession, and other aspects of village life. It is also a theory of history where genesis, finality, and apocalypse are laid out on the space between the pinky and the nose."
Alex Golub illuminates the counting system of the Ipili tribe of Papua New Guinea, in response to much discussion of the ethnomathmatics
at Leuschke.org. [more inside]

Cheney in Numbers.
It's hard to spin hard cold numbers. Here's a few:
*Cheney's 2000 income from Halliburton: $36,086,635
Increase in government contracts while Cheney led Halliburton: 91%
*Minimum size of "accounting irregularity" that occurred while Cheney was CEO: $100,000,000 (One hundred MILLION dollars)
*Number of the seven official US "State Sponsors of Terror" that Halliburton contracted with: 2 out of 7
*Pages of Energy Plan documents Cheney refused to give congressional investigators: 13,500
*Amount energy companies gave the Bush/Cheney presidential campaign: $1,800,000
also loved this quote:
"Cheney and Bush want privacy for their conversations, but not for anyone else's." --Tony Mauro in USA Today, Feb. 27, 2002

Can you stump the Encyclopedia of Integer Sequences?
Every identifiable sequence known to man, including:
Name: Busy Beaver problem: maximal number of steps that an n-state Turing machine can make on an initially blank tape before eventually halting.
Comment: The sequence grows faster than any computable function of n, and so is non-computable.
If your sequence does not appear there, you might want to try the Super Seeker

The Secret Lives of Numbers
A couple of programmers took it upon themselves to use "a popular search engine"(just say it: Google) to determine the relative popularity of every integer up to one million. Even if you just take it as a big case of overthink, it's kind of fun to play with the Java-based visual representation, which provides some of the terms associated with the numbers as you click on them.

...harnessing the power of Lava Lite® lamps to generate truly random numbers....
That's a bold statement, but who am I to doubt the power of the lava lamp
. The mathematical purist may disagree with the "truely random" part, but this geek speak
convinced me that LavaRand can handle all my random number needs.

Mathematician Bums Out Entire Scientific Community
His "Omega" number--infinite and incalculable--guts hopes for pure mathematics, physicists' hopes for a Theory of Everything, and is just in general kind of bafflingly cool. Builds on the whole Godel/Turing foundation of hopelessness!
