A Cardiod, a lovely mathsy heart shape, can be constructed as shown in the animation as the combination of many circles generated from a single underlying circle. This shape describes the sensitivity regions of many directional microphones. [more] [code]

I can’t help it with the bad math humor, guys. Sorry*.

Visualizing Prime Numbers
Jason Davies has created a way to visualize prime numbers as periodic curves (curves that repeat every n points). Wherever only two curves intersect (for 1 and the number), that’s a prime.
Play with the interactive, zoomable version here. Awesome stuff!

One of the First Computer-Generated Films, from 1963 - AT&T Archives
A short, simple 3D animation of a satellite object orbiting a globe:
This film was a specific project to define how a particular type of satellite would move through space. Edward E. Zajac made, and narrated, the film, which is considered to be possibly the very first computer graphics film ever. Zajac programmed the calculations in FORTRAN, then used a program written by Zajac’s colleague, Frank Sinden, called ORBIT. The original computations were fed into the computer via punch cards, then the output was printed onto microfilm using the General Dynamics Electronics Stromberg-Carlson 4020 microfilm recorder. All computer processing was done on an IBM 7090 or 7094 series computer.
Zajac didn’t make the film to demonstrate computer graphics, however. Instead, he was interested in real-time modeling of a certain theoretical construct. At the time, The Bell System was still deeply engaged in satellite research, having launched Telstar the previous year, with plans to continue developing communications satellites. Zajac’s model is of a box (“satellite”), with two gyroscopes within. In the film, he was trying to create a simulation of movement — the pitch, roll, and yaw within that system.
Structures 4 by Atelier Olschinsky
Another set of illustration work by an artist who successfully adopts an abstract realism approach. In this collection, familiar urban motifs become recursive fractal compositions with a surreal structural effect.
Ten Disturbing New Facts About Math Textbooks
Some quick takeaways from the survey (via Edudemic):
- About half (49%) of teachers surveyed believe their textbooks are ineffective for English Language Learners.
- Nearly all (89%) of K-8 math teachers say they need to supplement their text with additional materials because they’re so inadequate.
- The most widely used textbook is also the lowest rated.
- 4 out of 5 (82%) teachers feel compelled to create their own / borrow materials from other teachers.
