The Shape of Sound

By -
In Diane Ackerman's description of sound she says that sound is air molecules that move in waves that begin with the movement of any object. These waves enter the outer ear which is like a funnel and vibrates the eardrum, the hammer, anvil and stirrup bones (the tiniest bones in the human body) which press fluid in the inner ear triggering the cochlea hairs which signal nerves. However, there is one misconception present very early on in this explanation. Sound does not simply travel in waves. Instead sound travels in spheres. Scientist John Stewart Reid was the first to officially introduce this new understanding of sound. Here is an excerpt from his writing on the subject:

"Sound in air is the transfer of periodic movements between adjacent colliding atoms or molecules. This sonic energy typically expands away from the site of the collisions as a spherical or bubble-shaped emanation, the surface of which is in a state of radial oscillation.
The sonic bubble expands and contracts with the same periodicities as the initiating sound source. The accepted model of sound waves is incomplete because it uses the graphical representation of the mathematical law of sinusoidal energy, typically given as amplitude in the vertical axis versus time in the horizontal. While this is correct in terms of graphical depiction, it is not how the energy actually moves through space."

More accurate depiction of sound as a sphere frozen in a moment in time, and cymatic cross-section

There is science that studies sound called cymatics. Cymatics is able to more accurately offer a visual representation of sound, and from this science were are beginning to learn more about the complexity and power of sonic vibration not only as a sensory experience but also on the level of vibration that we cannot not consciously perceive. In this way sound may in some way be connected to a 6th sense type of experience.

The most primitive sense

Smell the Flowers by Kirsten Star Smell, to me, is the most primitive sense. When most mammals are born, they immediately can recognize their mother’s smell and form an attachment to that smell. Mammals like puppies are almost entirely limited to only the sense of smell until they develop more of their other senses. The sense of smell also becomes the most primitive when considering humans and the phenomenon of perfume. For years, humans hunted certain animals for the purpose of obtaining the musk produced in the anal gland. This musk in small doses can act as an aphrodisiac when put into a perfume even though it has incredibly primitive origins. Though most of Western culture has an aversion to smells considered gross or undesirable, the wealthiest of women are still willing to pay heavy prices to spray a smell once obtained from the anal glands of other animals. The sense of smell is not something that humans can control and adjust but rather it is only changed by evolution over

Cannibalism and Symbolism

By -
Symbolism plays an important role in religious ceremonies because people cannot have the divine being where they want him all the time. So they start creating ways to be in touch with God. Such as in Christianity, eating bread is symbolized to be eating God-made flesh. There are similar rituals in Judaism where they eat the food of God. A big difference between taste and the other senses is that the object that is being sensed is internalized, whereas all the other senses use an external sensation. Taste cannot extend anywhere like the other senses can. This allows the humans to have no barrier between the divine (symbolized as food) and themselves. This is the closest they can get to God, but internalizing Him.  This thought of getting the closest they can to someone by ingesting and gaining power from it led my mind to wander to the thought of serial killers that also happen to be cannibals. I know that it might be a stretch, but there are some similarities. I als

Wrap-Up Post

Alright, let’s tie this up in a nice little bow. I genuinely did not know what to expect coming into this class. The extent of my knowledge of the senses comes from elementary school when we had to make it a little song to get the information through our tiny heads. Beyond that, everything seemed pretty cut and dry. We have five senses. We need to use all of them to survive. It’s as simple as that. I did not know how there was enough to talk about the senses to fill an entire college course, especially one specifically regarding the relationship between the senses and religion. But the fact that we were barely able to fit all the content in before the semester ended proves just how wrong I was. Let’s talk about why that is and what some of the things I learned were. First off, even the most basic assumption about the senses, that there are five of them, was questioned immediately. The sixth sense may not have been as clearly defined as the other senses, but there was certainly a lot to
