In the programming area, the sorting algorithms are very important. They are used to organize elements in arrays and other forms of data organization. There are many such algorithms, varying both in complexity and efficiency. The best known, at least when I was Science Computer, was the bubble algorithm, insertion and selection.
Behold, an unoccupied programmer decides to find out what the sound that many of these sorting algorithms do. And he can record a video showing that sound along with a graphical representation of a vector being ordered. The result was published on YouTube in April and is below.
