Web Game Helps Predict Spread of Epidemics
An anonymous reader writes "Using data from the web game wheresgeorge.com, which traces the travels of dollar bills, scientists have unveiled statistical laws of human travel and developed a mathematical description that can be used to model the spread of infectious disease."
Here is the blurb in Nature, Nature's Editor's Summary
and here is the PDF research paper The scaling laws of human travel.
I remember coming across this site several years ago (2001? 2002?) and just for fun entered a couple bills to see how it worked. Since then, I totally forgot about it until this Slashdot reminded me! I'm very curious to find out how 'my' bills are doing these days. I do remember, however, reading somewhere that the average lifespan of a one dollar bill is less than a year or two, so the chances my bills made it past the few months I handled them may be slim.
The is no "business model". The site DOES NOT SELL RUBBER STAMPS. It stopped selling rubber stamps in 2000 at the request of the U.S. Secret Service.
It's also not "these guys"... it's "this guy".
Please stop spreading this disinformation.
So he created a virus that killed only women, and released it to the world via paper money.
The only downside is the book had about 3x as many words as a gripping novel would have, or I was a bored teenager; I haven't read it in a dog's age.
I feel fantastic, and I'm still alive.
But if you go to the wrong URL, it will be corrected automatically.
And it was only temporarily down.. it's back up now.
I spend a significant amount of time EVERY DAY to ferret out fake data. I have several automated processes that search for and remove any data that does not fit certain criteria. I take this site, and the data integrity very seriously, so I take personal offense to your offhand, unfounded, and ignorant comments.

Kind of like how Heisenberg's principle and statistical mechanics aren't mutually exclusive, for the physics crowd out there.
It's been some time since I've read the book but as I recall it was to get revenge on the men who took his wife from him - so 'I'll take your wife from you'. Since he did not know exactly who did this to him he decided to 'get everybody'. Radical isolation to keep the infection from spreading was tried. How the book ended I can't remember.

So did the researchers who used your data set take this into account? For that matter, did you have a significant role in the study beyond providing the data set?
I did not take part in the study, I only provided the data. The data removed from the data set are entries that are obviously fake - for instance two entries thousands of miles apart, entered from the same machine. Or people who intentionally snail-mail bills to each other.
First, only the FRB can judge if a bill is unfit to be re-issued. You can't, a bank can't, a merchant can't. Second, the website simply tracks bills by serial number, and works if bills are marked or not. The site does not encourage or endorse the defacement of currency. I am forbidden by law to sell rubber stamps that do so. What the users do and purchase on their own accord is between them and their lawyer.
Europeans can track their euro-bills here: http://www.eurobilltracker.com/
As I said in my previous post, nothing on the site endorses nor encourages defacing currency. But I guess you didn't actually read what I wrote.
