When Art is combined with Science and vice versa, it has a magical quality! I suppose if you are movie goer, you should be intensely aware of it, especially if you watched this year’s Oscars front runner – The shape of water.
People have done some wonderfully inspiring stuff around illustrating and promoting understanding of algorithmic (and mathematical) concepts. Sorting algorithms, which deal with arranging objects (say, numbers) in ascending or descending order somehow lend themselves to a few such creative exercises. Here are two examples which I really enjoy using while teaching my Algorithms classes. The best quality they have is they wake up students (with a bang, I should say) from the deep sleep induced by a tough lecture, and even infuse some with a love of algorithms (at least I fantasize so).
- Sound and Fury: The video below titled 15 sorting algorithms in 16 minutes, probably my favourite ‘cool-aid’, is by Timo Bingmann from Kalsruhe (KIT). It’s quite fascinating to see how he uses the numeric values to generate the plots and the relative difference of the compared values to generate the sound. The video has a mere 4.1 Million views so don’t stress if you add a bit more to the count!
The closest I came to doing something like this is when as a high school student, I wrote a program in the programming language Basica that plotted the initials of a girl I liked using a cosine function. Do try that some time!
Details about the above video and its companions, the algorithms behind their generation and the complete source code is available at http://panthema.net/2013/sound-of-sorting/ – if you like, download and have fun!!
2. Sorting Come Dancing: Now, on to the ‘sorting dances’. This group Algorhythmics from Sapentia University, Romania, seem to have a real affinity for dancing their algorithms! They have a number of well known folk dances which end up doing sorting or even other things such as linear and binary search. Watch the numbers Quick Sort themselves by doing a Hungarian dance!!
I wonder how another dance, say an Indian classical dance, effect quick sort! ;). Watch more of their dancing at their youtube channel: AlgoRythmics
I have issued a challenge to my UG year 1 Algorithms class to see if they can come up with something similarly creative. Considering that Loughborough University is ranked the number 1 sports university in the world, I wouldn’t be surprised if it had some sporty angle to it. Let’s wait and watch!
