The dark side of the cell

In class today we will listen to excerpts from Anne Niemetz and Andrew Pelling’s installation “The Dark Side of the Cell.” For more information about their audio and video recordings/compositions visit the website:

Figure 1. a) An optical microscope image of a triangular AFM cantilever. At the apex of the triangle is a small tip that is barely visible and appears as a small block spot. A cartoon zoom of the side view of the cantilever shows the pyramidal shape of the tip that has an approximate radius of about 20 nanometers. In b) a schematic of the AFM cantilever is shown. The tip itself has a 35 degree half opening angle. c) A cartoon of the AFM setup. The AFM cantilever is mounted on the end of a tube piezoelectric crystal. As the crystal moves the tip over the surface, a laser monitors the tip displacement. The laser is bounced off the back of the cantilever into a position sensitive photodiode that records the cantilever motion. A computer assembles a three dimensional image based on this data.

“One drop” drumming pattern

Here are some explanations of the “one drop” pattern that is characteristic of roots reggae.

Here is a more technical explanation of how to recreate the “One Drop” rhythm using a sequencer music program: “Feel it in the One Drop

Listening to Taste

Are the senses always separate? The condition known as synaesthesia, or the blending of sensations in a given experience, has come up in our discussions recently. Here is an example of researchers blending hearing and tasting in order to provide more accurate information for food scientists who wish to better understand “mouthfeel.

Labrynthitis, Jacob Kirkegaard

In class on January 16 we listened to a snippet of Jacob Kirkegaard’s composition in order to think about what it means to listen, and how hearing is active rather than a passive. More information about the composition, including a detailed description of the workings and characteristics of the human ear that Kirkegaard made use of in his composition may be found at the link below. You can also listen to the recording of the composition again, and experiment with what it sounds like on a variety of speakers/headphones.
