Remember photographer Noah Kalina? He took a picture of himself every day for six years and made a time-lapse video with the photos. The Simpsons even did a spoof that showed Homer’s life over a couple of minutes. Kalina’s kept the picture-taking going, and it’s been twelve and a half years now. He made a new video.

Six years is a long time, but you didn’t see that much change in the first video. In this one, you can start to see the age in his eyes. The forty-year update will be something to see.

Nancy Lublin, CEO of Do Something, gives a five-minute TED talk on the potential in analyzing text messages. During a texting campaign, Do Something started to receive texts from troubled teenagers, that ranged from bullying to rape, which led to the organization’s work in setting up a texting hotline. Lublin hopes that, once the system is built, the data gathered from these messages can be used as a census of problems, and can perhaps be used in the same way that Target uses data to figure out if women are pregnant — but to save lives, instead of figuring out what coupons to send.

After identifying 129 metropolitan regions that represent 35 percent of the world’s urban population, LSE Cities mapped some of the densest areas with a simple black and white color scheme. The patterns reveal a footprint of where the much of the world’s population lives.

To get a sense of the spatial dynamics of these city regions, we mapped 12 cases at the same scale with core built-up areas in black and peripheral areas in grey. By comparing the footprint of the world’s largest urban conurbation in Tokyo with Atlanta, our sample’s most land-hungry city region, we see that roughly the same amount of land is occupied by 42 million as by 7.5 million people. Meanwhile, the map of London shows that 14 million people are spread across South-east England.

In other words, that’s a whole lot of people packed into Tokyo. I wonder what these maps would look like with Tokyo density.

Feeding off the momentum from Stephen Wolfram’s personal analytics earlier this year, Wolfram|Alpha launched Facebook Analytics, which spits out graphs about your profile and your friends. You can see your activity over time, weekly distributions, and some general information about how people like and comment your status updates.

I’ve only updated my Facebook status a few times this year, so the profile-focused information is interesting to me, but the second half of the report provides high-level aggregates about your friends. For example, I’m apparently at a stage in life where most of my friends are either married or in a relationship. You can also see how your friends are connected via a network graph.

So you get more detail than you do out of current infographic-generators. The hook though is the links within the report that lead to information about your birthday or where you were born, kind of like when you end up reading about sasquatch on Wikipedia when your original search was actually work-related.

Horace Mitchell, director of the NASA Scientific Visualization Studio discusses the process behind their visualization that shows estimated surface currents around the world, Perpetual Ocean.

Once we have the data set, then we bring two things to bear. I’m a scientist by training — I have a doctorate in physics and I did research for about a decade — but everyone in my group has a level of understanding what the point is of all these animations. We know what we’re doing, and what we’re trying to bring out. Then, the team is amazing — working together, they play off of each other and every person in the team has a separate project they’re working on. They’re always bouncing ideas off of each other. As a result, over the last 10 or 20 years, we’ve gotten very good at figuring out what we can do. We have tools we can bring out at the drop of a hat to do certain kinds of visualizations. But we’re always thinking about the next thing, and what we can’t do yet.

People miss that very first part a lot of the time: “Once we have the data set…” No data means nothing to show.

The fictional map of physics by Bernard H. Porter in 1939 reads:

Containing a brief historical outline of the subject as well be of interest to physicists, students, and laymen at large. Also giving description of the land of physics as sen by the daring souls who venture there and more particularly the location of villages (named after pioneer physicists) as found by the many rivers. Also the date of founding of each village. As well as the date of its extinction and finally collection of various and sundry symbols frequently met with on the trip.

I nearly failed my advanced physics in engineering courses in college, so a lot of this is lost on me, but it feels very xkcd-like (despite being made seven decades ago).

Photographer David Johnson took long-exposure shots of fireworks. Fireworks already leave trails when they go off, the long-exposure versions create a spiky ball effect. Pretty. [via]
