The Visual Patterns of Audio Frequencies Seen through Vibrating Sand

Youtube user Brusspup (previously here and here) who often explores the intersection between art and science just released this new video featuring the Chladni plate experiment. First a black metal plate is attached to a tone generator and then sand is poured on the plate. As the speaker is cycled through various frequencies the sand naturally gravitates to the area where the least amount of vibration occurs causing fascinating geometric patterns to emerge. There’s actually a mathematical law that determines how each shape will form, the higher the frequency the more complex the pattern.

Broidery on a medieval page

Holes in the pages of medieval books are common. They were easily made (by the parchment maker’s knife), as in this wonderful case. Fixing it by stitching the hole together with strings of parchment is also common: parchment makers did it all the time, leaving behind “scars” on the page. What is totally unusual, however, is the repairs seen in this 14th-century book in Uppsala, Sweden. The damage is repaired, or at least masked, by good old broidery. It was done by the nuns who purchased the book in 1417. It is delightful to think that they took the effort to make a medieval hole disappear by replacing it with patterns like this, made up from pieces of silk in the most vivid of colors.

Tom Beddard (aka subblue) has been responsible for some of the most fascinating work being done with fractals. His totally mesmerizing video of fractal shapes morphing into one another was one of the first things I posted on this blog.

In his series Fabergé Fractals he has created digitally generated objects with designs as intricate as the eggs they’re named after. 

Beddard on his work:

The 3D fractals are generated by iterative formulas whereby the output of one iteration forms the input for the next. The formulas effectively fold, scale, rotate or flip space. They are truly fractal in the fact that more and more detail can be revealed the closer to the surface you travel.

The fascinating aspect is where combinations of parameters can combine to create structural “resonances” of extraordinary detail and beauty—sometimes naturally organic and other times perfectly geometric. But then like a chaotic system it can completely disappear with the smallest perturbation.

Creating works cited for imaginary papers using our school’s really awesome online library catalog: fake it until you make it, basically.

This the best idea ever.Ok, that’s a bit dramatic, but I have a confession: I hate teaching MLA format and Works Cited pages. I hate it so much. The kids use it so rarely, and it so BORING, and in college they’ll just use the Purdue OWL anyway, right?But this. This, I can do.

For Homebound Students, a Robot Proxy in the Classroom

Lexie Kinder solves problems during math class, earns gold stars from her teacher and jokes with classmates at her elementary school.
Born with a chronic heart disorder that weakened her immune system and made attending school risky, Lexie, 9, was tutored at her home in Sumter for years. But this spring, her family began experimenting with an alternative — a camera-and-Internet-enabled robot that swivels around the classroom and streams two-way video between her school and house.
“She immediately loved the robot,” her mother, Cristi Kinder, said, of the device, called a VGo, which Lexie controls from her home computer. Lexie dressed up the robot, which is about the height of her third-grade classmates, in pink ribbons and a tutu, and she renamed it Princess VGo.
A small but quickly growing number of chronically ill students — at least 50 across the country — now attend school virtually with what are called “remote presence robots.” The technology is still expensive (a VGo costs $6,000, in addition to $1,200 a year for maintenance and other costs) and imperfect (when the robot loses its Internet connection, it goes lifeless and must be pushed).
