The Pitch Drop Experiment

Geek Alert! How long is the longest continuous running science experiment? Eighty-five years, so far. It all began in 1927 when Thomas Parnell, a physics professor at the University of Queensland in Australia, set out to show his students that tar pitch, a derivative of coal so brittle that it can be smashed to pieces with a hammer, is in fact a highly viscous fluid. It flows at room temperature, albeit extremely slowly. Parnell melted the pitch, poured it into a glass funnel, let it cool (for three years), hung the funnel over a beaker, and waited.
Eight years later …a dollop of the pitch fell from the funnel’s stem. Nine years after that, another long black glob broke into the beaker.

SOPA Explained

SOPA is an acronym for the Stop Online Piracy Act. It’s a proposed bill that aims to crack down on copyright infringement by restricting access to sites that host pirated content.

Opponents say that it violates the First Amendment, is Internet censorship, will cripple the Internet, and will threaten whistle-blowing and other free speech actions. Opponents have initiated a number of protest actions, including petition drives, boycotts of companies that support the legislation, and planned service blackouts by English Wikipedia and major Internet companies scheduled to coincide with the next Congressional hearing on the matter.

Why it matters to you. Why this matters to sites like Wikipedia.
Laurence H. Tribe, a Harvard University professor of constitutional law, released an open letter on the web stating that SOPA would “undermine the openness and free exchange of information at the heart of the Internet and, it would violate the First Amendment.
