From a collection of his papers recently acquired by The Library of Congress, a 1954 reading list from physicist Carl Sagan. Huxley, Plato, Shakespeare, and the Bible are all on there among many others. If I understand mathematics properly, and I think I do, using the associative property, if you read all these books, you will become as smart and cool as Carl Sagan was. Or is it the transitive property?
This is a bit of a head-scratcher...the guy behind the Family Guy (Seth MacFarlane) is teaming up with Carl Sagan's widow and Neil DeGrasse Tyson to do a sequel to the landmark science series, Cosmos. The series will air in primetime on Fox.
The producers of the show say the new series will tell "the story of how human beings began to comprehend the laws of nature and find our place in space and time." They go on to boast: "It will take viewers to other worlds and travel across the universe for a vision of the cosmos on the grandest scale. The most profound scientific concepts will be presented with stunning clarity, uniting skepticism and wonder, and weaving rigorous science with the emotional and spiritual into a transcendent experience."
I'll be tuning in but will be pleasantly surprised if it does well in the ratings or is any good.

If you want to make an apple pie from scratch, first you must invent the universe.
That's Carl Sagan in Cosmos. Here's the recipe for Carl's apple pie.
Maybe you're tired of un-pop-music-like things being run through Auto-Tune, but I'm not quite there yet. This Auto-Tuned Carl Sagan mix is very nearly sublime.
The entire Cosmos series is available for free on Hulu, in 480p no less (US only). From the Wikipedia:
[Cosmos] covered a wide range of scientific subjects including the origin of life and a perspective of our place in the universe. The series was first broadcast by the Public Broadcasting Service in 1980, and was the most widely watched series in the history of American public television until 1990's The Civil War. It is still the most widely watched PBS series in the world. It won an Emmy and a Peabody Award and has since been broadcast in more than 60 countries and seen by over 600 million people, according to the Science Channel.

A map of the Milky Way done in the style of the London tube map.
I was re-reading Carl Sagan's novel Contact recently, essentially a series of arguments about SETI wrapped into a story, and he alludes to some sort of cosmic Grand Central Station. That, coupled with my longtime interest in transit maps, got me thinking about all of this.
At the very moment that humans discovered the scale of the universe and found that their most unconstrained fancies were in fact dwarfed by the true dimensions of even the Milky Way Galaxy, they took steps that ensured that their descendants would be unable to see the stars at all. For a million years humans had grown up with a personal daily knowledge of the vault of heaven. In the last few thousand years they began building and emigrating to the cities. In the last few decades, a major fraction of the human population had abandoned a rustic way of life. As technology developed and the cities were polluted, the nights became starless. New generations grew to maturity wholly ignorant of the sky that had transfixed their ancestors and had stimulated the modern age of science and technology. Without even noticing, just as astronomy entered a golden age most people cut themselves off from the sky, a cosmic isolationism that only ended with the dawn of space exploration.
That's Carl Sagan in Contact from 1985. The effects of light pollution were documented in the New Yorker last August.
Several episodes of Carl Sagan's Cosmos series are available on Google Video. They were all there at some point, but it looks like some got taken down.

The New Yorker recently ran a feature on how a couple of mathematicians helped The Met photograph a part of The Hunt of the Unicorn tapestries. That same week, they ran from their extensive archives a 1992 profile of the same mathematicians, brothers David and Gregory Chudnovsky. The Chudnovskys were then engaged in calculating as many digits of pi as they could using a homemade supercomputer housed in their Manhattan apartment. There's some speculation that director Darren Aronfsky based his 1998 film, Pi, on the Chudnovskys and after reading the above article, there's little doubt that's exactly what he did:
They wonder whether the digits contain a hidden rule, an as yet unseen architecture, close to the mind of God. A subtle and fantastic order may appear in the digits of pi way out there somewhere; no one knows. No one has ever proved, for example, that pi does not turn into nothing but nines and zeros, spattered to infinity in some peculiar arrangement. If we were to explore the digits of pi far enough, they might resolve into a breathtaking numerical pattern, as knotty as "The Book of Kells," and it might mean something. It might be a small but interesting message from God, hidden in the crypt of the circle, awaiting notice by a mathematician.
The Chudnovsky article also reminds me of Contact by Carl Sagan in which pi is prominently featured as well.
According to Wolfram Research's Mathworld, the current world record for the calculation of digits in pi is 1241100000000 digits, held by Japanese computer scientists Kanada, Ushio and Kuroda. Kanada is named in the article as the Chudnovskys main competitor at the time.
(Oh, and as for patterns hidden in pi, we've already found one. It's called the circle. Just because humans discovered circles first and pi later shouldn't mean that the latter is derived from the former.)
