Within Invisibility by Jiayu Liu is an installation powered by the wind of 40 Chinese cities.
Liu on her work:
What if we use wind to represent wind?
This project is about nostalgia, personal investigation, and testing the boundaries of data visualisation, and creating a multisensory experience of invisible data. Within Invisibility renders wind data into a multisensory experience. Live data comes from 40 major Chinese cities, each represented by two fans. Each fan shows a
Finding infrequent errors in MATLAB with DBSTOP if error Some errors happen in MATLAB infrequently. If you don’t know the conditions when they occur, setting a breakpoint might not work. Using DBSTOP if error will have MATLAB stop on a line in the editor only when the error condition is tripped.

It’s been a while since we looked at American Community Survey data in Wolfram|Alpha. Our first efforts included surveying ACS data related to education, income, and diversity, only touching the tip of the iceberg. Recently, we took a deeper look at the data to unearth some of the least “average” communities in the US. As [...]
In my last post I talked about how to plot polar curves in Geogebra. As I neared the end of the post I remembered how the use of sliders can enhance this topic. Below is a polar graph plotter. You can try this out now by dragging the slider alpha from 0 to 360 degrees. Move the slider back to 0 degrees and type in another function such as 3cos(5x), or 12/(2-sin(x)). A copy of this tool is available from the Geogebratube site here. I always have so much fun
