Music Sales Data Visualization

Interactive work done by Graphic Design  Matteo Botto from Torino, Italy during semester abroad at the University of Canberra. He created an interactive project by visualizing the data of the global music sales per country in 2007.

The user can zoom and drag the map, show and hide the rulers, highlight the main features and by clicking on the objects the user can visualize the data. The data are: amount of sales, retail value, population, purchase value and purchase amount pro capita.

Optimized Descents

Many flights today are burning unnecessary fuel and creating excess noise because of stairstep descents and extra long flight paths. This visualization shows how GE's flight management system might help to optimize descents, reducing fuel consumption and CO2 emissions at three sample airports.

Roberto Carlos Impossible Soccer goal "no fluke" - say Physicists

In 1997, Brazilian soccer player Roberto Carlos scored on a free kick that first went right, then curved sharply to the left in what looked like a physics-defying fluke. We’ve finally discovered the physics equation that shows it was no fluke.

Physicists have explained one of football's most spectacular goals.

Abstract. We discuss the trajectory of a fast revolving solid ball moving in a fluid of comparable density. As the ball slows down owing to drag, its trajectory follows an exponential spiral as long as the rotation speed remains constant: at the characteristic distance \mathcal{L} where the ball speed is significantly affected by the drag, the bending of the trajectory increases, surprisingly. Later, the rotation speed decreases, which makes the ball follow a second kind of spiral, also described in the paper. Finally, the use of these highly curved trajectories is shown to be relevant to sports. For more information visit New Journal of Physics website.
