Defeating earthquakes, and more free videos from the American Geophysical Union

Remember when you had to build a bridge out of popsicle sticks in high school science class? The goal was to construct the miniature bridge that could withstand the most physical stress. Your materials were just sticks and glue. So the real challenge was to find strong shapes.

On the day of testing, we all learned very quickly what those shapes were. Bridges built out of lots of squares collapsed almost instantly. Bridges built out of triangles made the finals.

This is a pretty basic lesson, but it's not one that the global construction industry has learned yet, says the US Geological Survey's Ross Stein. Last week at the meeting of the American Geophysical Union, he began a talk on "Defeating Earthquakes" by demonstrating the difference between the cube-centric structures we build all over the world and how much stronger those structures can be if you just add triangles in the corners. It's a powerful demonstration of how simply having the technology to solve a problem isn't enough. You have to get people to use it.

This whole video is worth watching and easy for laypeople to follow. And it's just one of a huge collection of lecture videos from AGU 2012 that are now available online. They cover everything from the chemistry of lighting to the geology of volcanoes to the effects of space storms and solar flares. Very cool stuff!

Freaky Halloween snapshots: 1875-1955

Hallllowwair NewImageOssian Brown was a member of the dark, magickal electronic music group Coil and is currently in Cyclobe, a duo with his partner Stephen Thrower. Ossian is a strange attractor. Weird things find him. Like his exquisite collection of antique vernacular photographs of Halloweens past. Brown compiled his favorites of the freaky found photos, all dating between 1875 and 1955, into a gorgeous book titled Haunted Air.

After viewing the photos, filmmaker David Lynch said, "I was somewhere else. I thought I was someplace but now I didn't know what place. I seemed to be inside foreign worlds where there was some kind of troubling camaraderie -- as if a haunting joke was known to everyone but me and yet faintly I knew it too."

Last year, we featured selections from Haunted Air. Now is a lovely time to take another peek. Haunted Air: Halloween Photos 1875-1955

Videos of Japanese trains and train toilets

This playlist from YouTube user hideyasann features more than 100 short clips of trains and train restrooms in Japan. Most of the train videos are of trains pulling into a station, or changing tracks. Most of the toilet videos emphasize the flushing mechanisms—of which there are a surprising variety.

As a rail fan, it's interesting to see what so many different Japanese stations and trains look like. And there's no narration, so it's also interesting to watch these very matter-of-fact clips and think about the visual context they trigger in your head. Men in suits waiting on a platform for a train to change tracks—that's a scene from a serious drama about the inner psychology of a businessman. A shakey clip where the videographer walks towards an arriving train, and a station agent, while breathing heavily—that's totally a scene from a horror movie. I'm honestly not sure what to make of all the toilets.

It's also kind of awesome to just think about the level of obsession that went into this playlist. I'm not really sure what hideyasann is trying to document—Train variety? Train cleanliness? Is he or she just collecting the same footage from as many trains as possible? Whatever the goal, you can clearly see the love and fascination here. There's totally a Happy Mutant at work.
