24 hours on craigslist

Finally the entire award-winning 2003 documentary is available on youtube!

-- About this film:

In 1995 craigslist.org was born in the Bay Area: a free, down-to-earth and uncensored bulletin board that revolutionized the ease and speed with which people could communicate, exchange goods and services, and create community.  Primarily focusing on housing, jobs, items for sale and personal ads, the site soon became a hub for San Francisco's wired community.

2003.  Craigslist is big.  Really big.  Over 1/3 of all Bay Area internet users utilize craigslist on a regular basis. Outside of the Bay Area, craigslist has spread to 31 cities across the globe, with no sign of slowing.  In San Francisco alone, the site receives over 23,000 posts daily, with page views close to 29 million daily.  With no advertising, no commercialization and only word-of-mouth promotion, craigslist has become a phenomenon.  And it's still free.

Our film:

From a single post on craigslist we assembled eight film crews and a soundtrack to document a random day-in-the-life of what has evolved into the world's largest community board. Not just the "Best-Of" or the "Success Stories", but a real, down-to-earth look at the fastest-growing grassroots cyber-community in the city that started it: San Francisco.

This is that day: August 4, 2003:

An Ethel Merman drag queen searches for the perfect backup band for her Led Zeppelin covers. A suburban professional woman assembles a diabetic cat support group. A couple seeks the perfect rabbi for their marriage.  An aging, would-be mother finds her ideal sperm donor. Doors for sale, one night stands, compulsive roommates, transsexual erotic services.  The mundane and the sublime, the ridiculous and the profound, all come together to paint a portrait of a thriving, humanistic community in the midst of an ever-accelerating culture.

BBC Horizon Project Poltergeist (Missing Neutrinos) - Full Documentary

This is the story of two genuine scientific heroes. For forty years, John Bahcall and Ray Davis were engaged in a single extraordinary experiment - to find out why the Sun shines. In the end they would triumph. Davis would win the Nobel Prize and, thanks to their work, a whole new theory about how the universe is put together may have to be created.

At the heart of this story is a tiny, utterly mysterious thing called a neutrino. Trillions of them pass through your body every second, touching nothing, leaving no trace. Yet neutrinos are one of a handful of fundamental particles in the universe, essential to every atom in existence and clues to what makes the Sun work. But their ghost-like quality made trapping and understanding them immensely difficult.

What then followed was a bizarre series of experiments. They led from a vat containing 600 tons of cleaning fluid, to a vast cavern in a Japanese mountain, to a hole in the ground in Canada two kilometres deep.

What they would reveal would stun the world of science. It seems that neutrinos may be our parents. They may be the reason why everything, including us, exists.
