## Anaxagorean Sensations

Events are characterized by the sensations they encompass. And describing events can be very intricate. So to limit complexity, we start making descriptions using just eighteen *Anaxagorean *sensations.

These privileged sensations are simple, common and unmistakable. We name them after the ancient Greek philosopher Anaxagoras of Clazomenae because he started connecting them to European physics. To be definite, we say that a sensation is **Anaxagorean** if it is white, black, red, green, yellow, blue, burning, freezing, warm, cool, tart, soapy, potable, brackish, savory, sugary, on the left-side or on the right.

EthnoPhysics depends on making binary descriptions of sensory experience. And binary analysis reduces all detail and subtlety to just two contrasting possibilities. So Anaxagorean sensations appear in opposing pairs.

Initially, sensations that are complex or ambiguous are not considered in this descriptive scheme, even if they are common and important. For example, the colour orange is not unmistakably red or yellow, it is a bit of both. It is not perfectly *distinct* from red and yellow, so it cannot be included in the set of Anaxagorean sensations.

The theory of EthnoPhysics is built-up from mathematical sets of sensations. Arithmetic and algebra are also based on set-theory. And the founder of set-theory Georg Cantor says that a set is “a collection into a whole, of definite, well-distinguished objects.”^{1}E. Kamke, *Theory of Sets*, page 1. Translated by Frederick Bagemihl. Dover Publications, New York, 1950. Or in another translation as, “definite and separate objects.”^{2}Georg Cantor, *Contributions to the Founding of the Theory of Transfinite Numbers*, page 85. Translated by Philip E. B. Jourdain. The Open Court Publishing Company, La Salle Illinois, 1941.

Moreover, distinguishability is required^{3}Wolfgang Pauli, *General Principles of Quantum Mechanics*, pages 117 and 123. Translated by P. Achuthan and K. Venkatesan. Springer-Verlag, Berlin Heidelberg 1980. to develop Wolfgang Pauli’s exclusion principle.

Anaxagorean sensations are building-blocks we can use to describe more complicated sensations. They *must* be distinct so that we can accurately count them, use mathematics to analyze the results, and thereby scientifically describe events.

## Sensory Events

An event is a discrete bit of consciousness; an occurrence, experience or incident. Not all happenings occur in the realm of the senses. But for physics, most events are sensory events.

Indeed reference sensations are selected for consideration exactly because experiencing one is a very common sensation for most people. So we assert the first hypothesis by defining a **physical** **event** as a mathematical set of Anaxagorean sensations. This definition formally limits the scope of EthnoPhysics.

Events are generically noted using a letter, usually , together with a subscript like this: . Here are some examples that are expressed using the icons for Anaxagorean sensations. If an event called was experienced as a burning red sensation, we could write

Another incident that felt like a freezing red sensation on the left could be represented as

As a third example, the occurrence of a tepid red sensation on the right might be expressed as

The characteristic that all these examples share is the visual sensation of redness. So we use the letter to label all of them. The descriptive method of EthnoPhysics combines sequences like these to build-up an account of more complicated experience.

## Chains of Events

Events are often arranged in ordered-sets called **chains of events**. Then the subscript in an event-name is used to indicate location in the ordered-set. In general any sensation can be used to organize order. And to be put in order, happenings must be somewhat different from each other.

But grouping phenomena together in a chain also implies that they have some common characteristics, at least enough to establish membership in the set. We often use the letter without a subscript to represent these common attributes. The chains themselves are usually referred to using the Greek letter as in

For a specific example, we can organize the red events described above into an ordered-set where they are ranked by their thermal character; from burning to cold

And here is another example where events are arranged by their somatic attributes, left to right

Please notice that ordering sets in these ways does not depend on any preconceived notions of space or time. Events are arranged using just their sensory qualities. But later we will use as a mathematical way of representing chronologically ordered experiences. Then as we go from discussing individual-events to chains-of-events our reports get animated. Chains may be called histories or processes. We can even think of them as little movies.

Some chains may repeat a sequence of events over and over again, like a movie loop. This makes them much easier to recognize and remember. Repetition, identification and detection are vital aspects of experimental science. So next we focus on these sorts of recurrent happenings.

## Orbits

Orbits are sequences of events that are repeated over and over again in some longer chain of events. Chains like these are used to mathematically describe phenomena that are repetitive or cyclical. Repetition is important so that these events are easy to recall. They are *memorable* events. More exactly, let be some finite selection of events written as

Let this selection be repeated over and over again to establish a longer chain of events called as

where etc. The repeated sequence of events is called a single **orbit** or an orbital-cycle of P. The longer chain is generically called an orbital chain-of-events. And sometimes, is also called a bundle of sensations because physical events have been defined from sensations.

Earlier it was suggested that a chain-of-events could be thought of as something like a movie. To illustrate this notion, here is an example of using repetitive sensations to make a boring movie. Consider that might be a somatic sensation, and perhaps that is a single-frame within the motion picture. The first thing that happens in this example is some sort of sound that is heard on the right-side

Then the next event is a somatic sensation on the left

These two sensations are bundled together into an orbit

and then repeated, over and over again

Right, left, right, left, right, left and so on … nothing else happens. So this movie is called *The Almost-Dead March*. Chains like this might seem a little tedious, but as we add more detail, they provide a basic structure for describing more complicated happenings in space and time.
