## Illinois Lottery Draws 666 on Heels of Obama Victory

The day after a senator from Illinois, is elected president, the Pick 3 lottery in Illinois comes up 666. It's happened before, notably in Pennsylvania (12 times, including one time as part of a scam and once earlier this year, in Maryland. Some are jokingly (I hope) calling him the antichrist as a result. Others, namely numbers geeks like me, are spending their lunch hours looking up the history of lotteries drawing triple numbers and sharing it with MetaFilter.

## ¡Atención!", "1234567890"

Find a short wave radio and before long you should be able to tune into The Lincolnshire Poacher - the station plays an introduction comprising part of the eponymous folk tune followed by a robotic female voice reading strings of numbers: listen! So called Numbers Stations have been a mysterious constant of short wave radio for several decades. The Conet Project [previously 1, 2, 3] has made a collection of the recordings available allowing you to listen to "Ready! Ready! 15728", "The Buzzer" (especially mysterious), "Gong Station Chimes", "Magnetic Fields" and many others.... [more inside]

## 15 bits of crypto should be enough for anybody

On May 13, security advisories published by Debian and Ubuntu revealed that, for over a year, their OpenSSL libraries have had a major flaw in their CSPRNG, which is used by key generation functions in many widely-used applications, which caused the "random" numbers produced to be extremely predictable.

## Prime Prize

In September 2006 the largest known prime number, a 9.8 million digit number, was discovered. If you find one over ten million digits you can win US$100,000 (of which you get to keep $50,000). No maths is required - just download the software and you're away. Warning: it takes about a month to run one primality check so some patience is required. Look out though Cooper and Boone look like they might beat you to it.

## It may be just a game, but it's serious business.

Running the numbers on Second Life. With Linden Labs' virtual world being taken seriously by journalists and even banks, it's clear that businesses see profits in virtual worlds. But with over US$800,000 in value changing hands in 24 hours it's becoming hard for even skeptics to deny the profit potential of Second Life. After all it's not just flying penis attacks. Not everyone agrees, however. How many of those residents just log in once, shrug then stay away?

## You have the right to remain innumerate...

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)

## Significant numbers

Significance of numbers. Not to be confused with the concept of "significant figures," this page lists the significance of numbers 0 through 1000.

*See!*"2 is the only even prime."*Hear!*"24 is the largest number divisible by all numbers less than its square root."*Thrill!*"3367 is the smallest number which can be written as the difference of 2 cubes in 3 ways." Whoa!## Lost and Found

## More on arithmetic in the Amazon

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.

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.

## Smelling Colors, Hearing numbers

"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 and mescaline 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?

## Cheney in Numbers.

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

Comment: The sequence grows faster than any computable function of n, and so is non-computable.

## The Secret Lives of Numbers

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.
