Lifehacker: "One of the more annoying things about Netflix, Hulu Plus, and Amazon's television streaming libraries is the vast difference between the selection available. It would be almost impossible to get a thorough idea of who has the better library without searching for hundreds of TV shows on each service and comparing them manually. So we did just that."

Feeling horny? Here's a visual and audio guide to diesel locomotive horns. A definitive resource. For example, most Amtrak locomotives have a Nathan Airchime KL5A installed. Ever hear a sick-sounding horn on a train? Don't miss the sections on **When bad things happen to good horns** (Scroll down on the KL5A page for one such section). Turn your speakers up and enjoy!

Closing in on the twin prime conjecture (Quanta) - "Just months after Zhang announced his result, Maynard has presented an independent proof that pushes the gap down to 600. A new Polymath project is in the planning stages, to try to combine the collaboration's techniques with Maynard's approach to push this bound even lower." [more inside]

The new largest prime number has been discovered! Why is this awesome? Because it is more than 17 million digits long. Also, the article contains quotes from mefi's own escabeche.

What is the smallest prime? "It seems that the number two should be the obvious answer, and today it is, but it was not always so. There were times when and mathematicians for whom the numbers one and three were acceptable answers. To find the first prime, we must also know what the first positive integer is. Surprisingly, with the definitions used at various times throughout history, one was often not the first positive integer (some started with two, and a few with three). In this article, we survey the history of the primality of one, from the ancient Greeks to modern times. We will discuss some of the reasons definitions changed, and provide several examples. We will also discuss the last significant mathematicians to list the number one as prime."

New math theories reveal the nature of numbers [1,2] - "We prove that partition numbers are 'fractal' for every prime. These numbers, in a way we make precise, are self-similar in a shocking way. Our 'zooming' procedure resolves several open conjectures, and it will change how mathematicians study partitions." (/.|via) [more inside]

Today would have been Indira Gandhi's 92nd birthday, had she not been assassinated by members of her own guard in her own backyard on October 31st, 1984 (I was there in New Delhi in a cab when the driver suggested it might be safer if he turned around and took me straight home). Often confused as a relative of the more famous Gandhi, fashionable, stylish and well groomed Indira was actually the daughter of India's first Prime Minister, Jawaharlal Nehru and used her married name, although divorced from her Parsi exhusband. Daughter and mother of Prime Ministers of India, she herself held office with an iron fist, remembered for the "Emergency", a brief period of martial law often overlooked in the democratic vibrancy of Indian politics. Will Mrs Gandhi's legacy of dynasty be continued by her half Italian grandson?

Joe Palca, a science correspondent for NPR's Morning Edition, was meditating on the best way to convey the magnitude of the world's largest known prime number, 2^{43112609}-1. He contacted H&FJ at Typography.com to discuss the implications of typesetting a number with more than twelve million digits. Crunching of numbers and fonts ensued.

Though foreign-born, he is often considered an American icon. His career may have peaked in the 80's and has certainly taken some questionable turns, but he's retained a cult following. Now he's having a true comeback, and though some may be displeased that he's "sold out", for him it's just the latest in a lifelong series of transformations.

In September 2006 the largest known prime number, a 9.8 million digit number, was discovered. If you find one over ten million digits you can win US$100,000 (of which you get to keep $50,000). No maths is required - just download the software and you're away. Warning: it takes about a month to run one primality check so some patience is required. Look out though Cooper and Boone look like they might beat you to it.

How not to move a satellite "As the NOAA-N Prime spacecraft was being repositioned from vertical to horizontal on the "turn over cart" at approximately 7:15 PDT today, it slipped off the fixture, causing severe damage."

Got a prime number? This formula can tell you. Dr. Manindra Agrawal, a professor of mathematics at the Indian Institute of Technology, and two doctoral students have solved a problem that has been puzzling mathematitians for literally centuries: testing with absolute certainty whether a number is prime.

Prime Time. A prime is a whole number divisible only by itself and 1. In Aesthetics of the prime sequence one can hear primes, view primes (here also) and test for primes. Quite interesting and not just for math geeks...
