Sonic Adds Sound to Logo, Recamán, Chaos - Cleve Moler on Mathematics and Computing

[poster]

I introduced Sonic in my blog post last month. Today I will use Sonic to add sound to the graphics from three old posts, the vibrating L-shaped membrane, the Recamán sequence and the chaotic behavior of the Swinging Sticks.

Vibrating L-shaped Membrane

For almost fifty years, I have wanted to hear the MathWorks logo. I have written about the L-shaped membrane many times, link #1, link #2, link #3.

Click on this link and listen to the audio in a Sonic movie of the vibrating membrane. The sound is generated by resampling one tone from a xylophone.

And here is one frame from the movie.



Recamán

The inventor of the Recamán sequence is a Columbian mathematician, Bernardo Recamán Santos. The sequence is A005132 in the OEIS, the On-Line Encyclopedia of Integer Sequences. Here is my blog post.

Click on this link and the listen to the audio in a Sonic movie of the Recamán sequence. The sound is generated by resampling the middle-C key of a piano.

Here is the last frame of the movie.



Swinging Sticks

The Swinging Sticks is a kinetic sculpture that exhibits chaotic behavior. I have added sound to my blog post about the sticks.

Here is the link to a Sonic movie of the Swinging Sticks. The audio is also generated by resampling one tone from a xylophone.

And, here is one frame from the movie.
