Twitter data shows trending topics tend to change rapidly

Twitter has taken a deeper look into how quickly its users change the terms or phrases they tweet on a given topic, or their churn rate, and released some of this data today.

For example, when Steve Jobs passed away, people began rapidly including "Steve Jobs" in their tweets, but a short while later "Apple" began trending, then "Pixar," and finally "Stay foolish."

"Looking at terms and phrases in Tweets and in real-time search queries, we see that the most frequent terms in one hour or day tend to be very … Read more

Titanic 'story map' delves into passengers' fates

The explosion of digital tools is opening new ways to explore the famous 100-year old Titanic shipwreck.

Mapping software company ESRI today released an interactive map showing the country of origin and ultimate fate of all the passengers on the Titanic. For first-time Titanic followers, the map displays the actual route of the seemingly invincible ship and the location in the North Atlantic where it struck an iceberg and sunk.

The mapping shows that many of the 2,200 passengers came from London and New York, but there were many from Scandinavia, eastern Europe, and Lebanon.

It also clearly shows … Read more

Play ball! Here's your MLB 2012 gaming roundup

Spring is in the air so you know what that means: the start of the 2012 baseball season. It's also the time of year where two game developers are competing for your hard-earned cash. So what's the best baseball game to pick up this year?

That will all depend on which console you own. Those with a PlayStation 3 have a choice, either MLB 12: The Show or Major League Baseball 2K12. On the other hand, Xbox 360 owners are locked in to only one title to satisfy their baseball itch. Unfortunately for the latter, this year's best baseball game is exclusive to the PlayStation 3.… Read more

Google artists create a real-time 'Wind Map'

Two technology artists who head Google's "Big Picture" visualization research group debuted a new project this week that shows a time-lapse animation of wind speeds across the U.S.

"An invisible, ancient source of energy surrounds us--energy that powered the first explorations of the world, and that may be a key to the future," the artists wrote in a post yesterday. "This map shows you the delicate tracery of wind flowing over the US right now."

The black map, simply named "Wind Map," displays white streaks that show varying wind speeds … Read more

NASA video visualizes a 'Perpetual Ocean'

NASA has released a computer visualization project called "Perpetual Ocean" that presents a data-created time lapse of the Earth's ocean and sea surface currents over a two-year period.

The animation (see below) shows the globe slowly spinning as white swirls curl and move in the water around landmasses. It looks as if Vincent van Gogh had painted into the oceans -- from the Gulf of Mexico to the Indian Ocean to the Black Sea.

Using NASA's Jet Propulsion Laboratory's computational model called Estimating the Circulation and Climate of the Ocean Phase II ( ECCO2), scientists simulated … Read more

Haptic app helps visually impaired learn math

For the blind and visually impaired, it can be nearly impossible to follow along when a math teacher spends most of a lecture in front of a blackboard or projector drawing shapes, parabolas, X-Y planes, and other visuals.

It's about time there's an app for that, thought mechanical engineering grad student Jenna Gorlewicz, who'd spent a few years at Vanderbilt's Medical and Electromechanical Design Laboratory miniaturizing endoscopic robotic capsules and was looking for a more people-oriented project.

So Gorlewicz, who says she loves both teaching and math, set out 18 months ago to try to develop a tablet app that uses haptic (or tactile) technology to help the visually impaired learn math and other subjects with a strong visual component.… Read more

Data mining's adult challenges

Probably no data-mining legend has been more pervasive than the "beer and diapers" story, which apparently dates back to an early 1990s project that data-warehousing pioneer Teradata (then part of NCR) conducted for the Osco Drug retail chain.

As the story goes, they discovered that beer and diapers frequently appeared together in a shopping basket on certain days; the presumed explanation was that fathers picking up diapers bought a six-pack when they were out anyway. This correlation was then used to optimize displays and pricing in the stores.

That's the story anyway. The reality, as best anyone can determine, … Read more

Braille texting app could have broader appeal

Most of us have at least tried to text without looking at our phones before. I confess to having shot off a quick message while stopped at a red light, or immediately following crazy goals and tackles at soccer matches, or even from the confines of my pocket at parties.

Now a free, open-source app called BrailleTouch is about to make this form of multitasking that much easier--for the visually impaired and sighted alike.

Designed at Georgia Tech, the app incorporates the Braille writing system into a touch-screen device. It essentially turns an iPhone's touch screen into a soft-touch … Read more
