The Internet Archive makes millions of digitized books available in the form of scanned pages, and these books are categorized into thousands of subjects. Focusing on book images, Mario Klingemann mapped subjects, based on tag similarity. Browse and discover new reading material.

This map offers an alternative way to browse the 2,619,833 images contained in the Internet Archive’s book collection. It shows 5500 different subjects which have been algorithmically arranged by their thematic relationships. The size of each link resembles the amount of images that are available for that topic. Clicking on a link will open the flickr page containing all the pictures for that subject. Rolling over a link will highlight all the topics that have a direct link with the subject.

I recommend browsing towards the middle in the medical cluster for some weird, old-school healing techniques.

Kirk Goldsberry, with help from Andy Woodruff, looked at how rebounds work in the NBA from a statistical perspective.

When a player shoots the ball and misses, there’s a tendency for the ball to go in certain directions and distances. Long shots for example often mean long rebounds away from the basket. After years of experience, players gain an intuition for these sort of bouncebacks and can try to position themselves for a rebound. These days more detailed data (via camera technology) is available, which is what these court maps show.

The interactive version in the middle of the article is especially interesting. Mouse over the court, and you can see where players typically rebound after a missed shot from the selected spot.

We know that there are more people per square mile in some places than others, but it can be a challenge to understand the magnitude of the differences. The same goes for the other way around. So Ben Blatt for Slate made the Equal Population Mapper, which lets you select an area of interest such as Los Angeles county or the state of Wyoming and see how many counties it takes to equal the population of said area.

For example, the above shows coastal counties as the point of reference, and you see the counties it takes to equal the coastal population in red. That’s a big section in the middle.

Might remind you of the Per Square Mile project from a while back which used cities around the world as point of reference and US states as the mode of comparison.

This is what you get when you group streets by their geographic orientation and color them accordingly with a neon paintbrush. From the ever curious Stephen Von Worley:

That’s every public street, colored by the predominant orientation of itself and its neighbors, thickened where the layout is most “grid-like” — to use an old-school woodworking metaphor, it’s as if we brushed some digital lacquer over the raw geographic transportation network data to make the grain pop.

Above is the map for Los Angeles. You see a lot of north-south grids in the red-orange color, but head towards the center of the map in the downtown area, and you get pockets of misdirection. In cities like Tokyo and Paris it looks like there’s no order at all to the roads, whereas Chicago’s road network looks like one big grid.

Lots to ponder, especially if you live in the cities.

Kate McLean, a PhD candidate in Information Experience Design at the Royal College of Art, is interested in the senses. More specifically, the non-visual ones. Mainly our sense of smell. As she tags herself as an olfactory experience designer, McLean goes on smellwalks, documents aromas, and then maps the “smellscapes.”

The map above is for Amsterdam, which you expect to smell like pot all day everyday and everywhere. But it didn’t.

Instead spring 2013 in Amsterdam revealed an abundance of the warm, sugary, powdery sweetness of waffles. Oriental spices emanated from Asian and Surinamese restaurants and supermarkets, pickled herring from the herring stands and markets — a link to one of the city’s key historical industries. Old books were detected in basement doorways and laundry aromas drifted up into the streets from Amsterdam’s many house hotels.

More smell maps: New York, Rhode Island, Paris, and Milan.

League of Legends is an online, free-to-play game that pits two teams of five against each other. The goal is to destroy the other team’s structures. The New York Times mapped 10,000 matches, played by 100,000 players, showing player movements over a quick thirty seconds.

As you’d expect, you see a lot of battles in the middle of the field and if you play the game, you’re likely to recognize the paths that people usually take. The best part is the character breakouts that show how certain “champions” move about.

Reminds me of the point cloud that shows over 11 million deaths in Just Cause 2.

Jeff Leek touches on concerns about point-and-click software to find the insights in your data, magically and with little to no effort.

I understand the sentiment, there is a bunch of data just laying there and there aren’t enough people to analyze it expertly. But you wouldn’t want me to operate on you using point and click surgery software. You’d want a surgeon who has practiced on real people and knows what to do when she has an artery in her hand. In the same way, I think point and click software allows untrained people to do awful things to big data.

Yep.

As a way to understand the deadliness and spread of Ebola, the Washington Post runs a simplified simulation of how long it’s likely to take for the virus to infect 100 unvaccinated people. The simulation runs alongside several other diseases for comparison, which provides the main takeaway: Ebola is much more deadly than the other listed diseases, but it spreads much slower.

Aatish Bhatia, a recent physics PhD, describes the forces involved to do a skateboard Ollie. It’s all about managing your center of gravity and applying variable amounts of torque to steer the board in the air. Yeah. It probably won’t help you skate any better, but it’ll help you appreciate the tricks a little more. [via kottke]

xkcd doing what xkcd does. Randall Munroe charts a brief timeline of interracial and same-sex marriage, through the lens of popular approval and population.

We browse online, we see ads, and we buy stuff. The better-targeted the ads are, the more likely that we buy stuff. So of course advertisers continue on ways to guess who you are and what you might want to increase the chances that you click and spend. Floodwatch, a Chrome extension by the Office for Creative Research and Ashkhan Soltani, lets you turn it around ever so slightly so that you can track what the advertisers serve you.

Philip Guo provides three practical reasons on why it’s worth pursuing a PhD.

Worth considering if you’re hemming and hawing about graduate school. Then again, it’s just as easy to come up with three practical reasons on why it’s not. Let’s not get into that though. Yeah, good luck with that.

Already on you way to a PhD? See also a survival guide to finishing.

As a way to bring context to the rarity of the 18-inning baseball game between the Washington Nationals and the San Francisco Giants this past weekend, Ross Benes compared other things that are 9.1 standard deviations from the mean.

An NBA team losing by 83 points. A 13.4-inch penis.

I’m not so sure how comparable those distributions are (as in deviations from the mean doesn’t always mean the same thing), but it’s an interesting exercise. At the very least, it’s a new tumblr in the making.

Remember that time you were sitting by the fire reading The Lord of the Rings and thought to yourself, “Gee golly. I sure wish I could have a map of my hometown drawn in the style of J. R. R. Tolkien’s map of Middle-earth. That sure would be swell. Gee willikers. If only.” Well, your dreams have come true. Geographer Stentor Danielson has an Etsy store called Mapsburgh where he draws real cities as Tolkien maps. He also takes custom orders.

I thought I linked to csvkit a while ago, but apparently not. If you deal with CSV data at all, you should know about the utilities suite that helps you format and re-format in various ways. Christopher Groskopf posted a list of quick things you can do with csvkit.

Over the last several months there have been two major releases of csvkit. These releases have brought long-awaited features such as Python 3 support, a csvformat utility and a new csvkit tutorial—not to mention a slew of bug fixes. To celebrate the latest release, here are eleven of my favorite awesome things you can do with csvkit. If you aren’t using it yet, hopefully this will convince you.

Fun things include a quick one-liner to convert an Excel file to CSV, switching to JSON, and easy CSV export from a database.

From Vox and research from Zuidhof et al., chickens are quite big these days.

The one on the left is a breed from 1957. The middle one is a 1978 breed. And the one on the right is a commercial 2005 breed called the Ross 308 broiler. They’re all the same age. And the modern breed is much, much, much larger.

When I was learning to cook, I’d follow recipes from my mom’s old cookbooks that she had when she was in college. One of my favorite dishes, steamed chicken with ginger and scallions, called for a three- to four-pound chicken. It totally screwed up my cooking times, and we ended up with many undercooked and overcooked chickens.

With Anheuser-Busch InBev rumored to have an interest in acquiring SABMiller and SABMiller trying to acquire Heineken, David Yanofsky for Quartz had a look at the structure of global beer distribution. The companies above, summing to six big beer distributors, accounted for half of the world’s beer sales, by volume.

This is important. And sorry AB InBev, FlowingData county ales isn’t for sale, no matter how many millions of dollars you throw my way. I’m serious. Stop calling me.

In a nutshell, the traveling salesman problem is as follows: “Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city?” Todd Schneider made an interactive that lets you punch in the cities yourself and then watch the process look for an optimum route. Fun to play with even if you’re not into processes. [Thanks, Todd]
