1% of women at age forty who participate in routine screening have breast cancer.
80% of women with breast cancer will get positive mammographies.
9.6% of women without breast cancer will also get positive mammographies.
A woman in this age group had a positive mammography in a routine screening.
What is the probability that she actually has breast cancer (+- 10% will do, just need a ballpark estimate)?

Next, suppose I told you that most doctors get the same wrong answer on this problem - usually, only around 15% of doctors get it right. ("Really? 15%? Is that a real number, or an urban legend based on an Internet poll?" It's a real number. See Casscells, Schoenberger, and Grayboys 1978; Eddy 1982; Gigerenzer and Hoffrage 1995; and many other studies. It's a surprising result which is easy to replicate, so it's been extensively replicated.)

Now that the 2008 election is over, reporters are spilling all the juciest, and previously off the record, gossip from the campaign trail. Much of it is about the infighting between Palin and McCain's staff, as Newsweek's treasure trove of post-election gossip reveals. However, perhaps one of the most astounding and previously unknown tidbits about Sarah Palin has to do with her already dubious grasp of geography. According to Fox News Chief Political Correspondent Carl Cameron, there was great concern within the McCain campaign that Palin lacked "a degree of knowledgeability necessary to be a running mate, a vice president, a heartbeat away from the presidency," in part because she didn't know which countries were in NAFTA, and she "didn't understand that Africa was a continent, rather than a series, a country

Video of our performance in Sep.27/2008 Midtown, St. Louis.
Unfortunately the quality of video is poor.

Disclaimer: Given that we finished choreography day before the performance, we didn't mess up too much. It will be polished by Chicago Salsa Congress in February.
I am very new to dancing and it was my first public performance ever. In real life I crunch numbers and grind Java :)

LIVERPOOL, England (AP) - What could be better after a hard day's sightseeing? Visitors to Liverpool, birthplace of the Beatles, can rest their heads in the Lennon or McCartney suites at the Fab Four-themed Hard Days Night Hotel that opened Friday.

More than 45 years after John, Paul, George and Ringo emerged from Liverpool's tiny, sweaty clubs to conquer the world, the Beatles industry is key to this battered-but-proud city's attempt to transform itself from fading commercial hub to thriving cultural hotbed. The 110-room Hard Days Night Hotel hopes to be its newest attraction. ''It's stunning, spectacular,'' said Julia Baird, John Lennon's half-sister, after being shown around the $1,300-a-night penthouse suite named for her brother. ''It's like Liverpool. Outside it hasn't changed, but inside there's rocketing change.''

This is a great commercial. Watch to the end.

I am off to California (Los Angeles) for Xmas break. If any of my LJ friends who lives LA wants to meet - just let me know!

Spoken word is a form of literary art or artistic performance in which lyrics, poetry, or stories are spoken rather than sung. Spoken-word is often done with a musical background, but emphasis is kept on the speaker.
One of the most common sorts of spoken word performances is performance poetry, where a poet either reads previously-published poems, or reads poems specifically written to be performed aloud. Another kind that has gained popularity in recent years is political and social commentary, done in such a way that it is, while still prose, somewhat more artistic than a typical speech. Spoken word artists are often poets and musicians. Spoken word gained notoriety in the late 1980s and early 1990s through the emergence of "poetry slams," where spoken word artists would square off in cabaret-style duels.
