The Main topic of this episode was Sonification of Data
The first featured data set was the 2011 earthquake catalog of events over Magnitude 4.5
the audio segment I shared was from Feb 1 – April 15
Question 1) What can you hear about the change in world wide earthquakes after the Tohoku earthquake? What can you hear that might be hard to see in the data set if you were to pause the video on April 15th?
The next featured data set was star oscillations by the artist Jeff Talman. I played a segment of his piece Nature of the night sky (2011)
Here are the stars used and my brief descriptions.
