  Ternary
Ternary digits are known as trits, analogous to bit.
Unbalanced ternary can be converted to balanced ternary notation by adding 1111..
Ternary is inefficient for human usage, just as binary is. Therefore, nonary[?] (base 9, each digit is two base-3 digits) or base 27[?] (each digit is 3 base-3 digits) is often used.

 Cantor set - Wikipedia, the free encyclopedia
To construct this function, consider the points in the [0, 1] interval in terms of base 3 (or ternary) notation.
Since there is a clear bijection between the ternary numbers consisting of only the digits 0 and 2 and the binary numbers consisting of the digits 0 and 1, it follows that the number of endpoints in the Cantor set is equal to the number of binary strings.
A closed set in which every point is an accumulation point is also called a perfect set in topology, while a closed subset of the interval with no interior points is nowhere dense in the interval.

 Cantor set
In this case we are removing everything between 0.01 and 0.02 in the first interval and between 0.21 and 0.22 in the second interval, or in other words, everything with a 1 in the second position after the point.
By the time you are done, the numbers which remain are those that can be represented in ternary (base 3) notation with no '1' in any position.
Therefore, the numbers in the Cantor set can be mapped onto the numbers in [0, 1] by replacing every 2 in the ternary expansion with a 1, and treating the result as a binary expansion.

 Discrete space - Wikipedia, the free encyclopedia
A product of countably infinitely many copies of the discrete space {0,1} is homeomorphic to the Cantor set; and in fact uniformly homeomorphic to the Cantor set if we use the product uniformity on the product.
Such a homeomorphism is given by ternary notation of numbers.
In the foundations of mathematics, the study of compactness properties of products of {0,1} is central to the topological approach to the ultrafilter principle, which is a weak form of choice.

This is called "balanced ternary notation," and is very interesting to play with; in particular, it makes negative numbers incredibly easy to handle.
You should be able to find a simple way to convert to this notation; I once found two rather different ways to do it.
In order to have only a single digit in each "ternary place," I had to rewrite the two-digit sums so that the Threes digit is added to the column on the left.

 Peter's personal rants. Today's special:A Rant Concerning the Number 3...
In decimal notation, the numeral 19 is shorthand for this expression:
Ternary also distinguishes between even and odd, but the signal is subtler: A ternary numeral represents an even number if the numeral has an even number of 1s.
In binary notation, the one-digit sequences 0 and 1 are obviously square free, and so are 01 and 10 (but not 00 or 11); then among sequences three bits long there are 010 and 101, but none of the other six possibilities is square free.

 The Baffling Binary Gigue
Thirteen of Froberger's gigues are written in binary notation and, according to Ferguson, it is supposed that they were nevertheless to be performed in either 12/8 or a very quick 3/4.
Even though Froberger notated the gigue in binary, he may also have expected that contemporaries would be familiar with the style in which gigues were performed, regardless of the score.
First, historical evidence suggests that it was to be performed in ternary, and both notational and theoretical sources point towards the "tripleness" of the gigue in general.

 The Shwah Language: Logic   (Site not responding. Last check: 2007-10-22)
It's called ternary because there are three digits and each successive place represents another power of three, but instead of using the digits 0, 1, and 2 (which I would call trinary or base 3), ternary uses the digits 0 and 1 and the minus sign −, which represents −1.
In ternary, the numbers zero and one are represented by 0 and 1, as in binary and decimal (base 10) notation.
In decimal notation, negative numbers are preceded by a minus sign, which is kind of an 11th digit, since you can't write all the integers without it.

 Mensuration in renaissance music - the rules
We'll write N for the longer note of the division (a breve when considering time, a semibreve for prolation), and n for the shorter one (thats is, a semibreve or a minim).
Following Apel, we will notate rest symbols and values between a pair of parenthesis: (N) et (n) for symbols seen on the document, (V) et (v) for their value once they've been interpretated.
In such a context dependant notation system, one must have some symbols keeping always the same value, and acting as milestones in the sentence, thus preventing context dependance to propagate too far away.

 Coloration in renaissance music
Before going on, be sure to be aware of the principles of mensuration - specially the ternary one, of course - that I won't recall here, to make the story shorter.
The word color is used, depending on authors, either in a broad meaning, whatever may be the binary or ternary nature of the application level, or in a more precise one, in which color is said for binary levels only, and hemiola for ternary ones.
Under white notation, coloured really means fl, thus some pieces were entirely written in fl just to illustrate their meaning of relief or sadness.

For the statements of these two, a sequence x of ternary digits will be said to have the universal top property if for any ternary sequence y if there is an odd integer t represented by yx then t has the top property.
Any ternary sequence x either has the universal top property or there is ternary digit d such that the sequence dx has the universal top property.
It will be noticed, however, that any odd integer whose ternary representation ends in 00111, does go to a multiple of 3 after 4 applications of h, as can be seen by the appearance of 00111 at the bottom of Fig.

The double-quote and vertical-bar notations are similar but distinct: double quotes indicate a character string containing the sequence of characters, whereas vertical bars indicate a symbol whose name is the contained sequence of characters.
The default notation for structures is #S(structure-name slot-name-1 slot-value-1 slot-name-2 slot-value-2...) where #S indicates structure syntax, structure-name is the name (a symbol) of the structure type, each slot-name is the name (also a symbol) of a component, and each corresponding slot-value is the representation of the Lisp object in that slot.

 Mensuration in renaissance music - introduction
Formerly some ratios were ternary, and this is more and more true when looking at older music, because these ternary ratios - which were said perfect - were the very foundation of the system.
Though the mensuration sign first specifies that a perfect note weights three smaller ones, this long note may be imperfected by a neighbouring smaller note, and then weights only two of them; the total values still amount to three, and this is called a perfection.
Ternary division of semibreves to minims is called prolatio major, and binary division is called prolatio minor.

Greetings Milady and the list, I will look through my files to see if I can identify this ballo for you, and to see if I can give you a reliable set of progressions (though I am not sure that music this early can be quantified with chord changes in a reliable way).
It is probably because there are hemiolas (emblematic of Italian dance music of the 16thC into the 17thC) such as a switch from a binary primary meter with a ternary secondary meter (eg 6/8 time), to a ternary primary meter with a binary secondary meter (eg 3/4 time).
It is customary to teach musicology students that because of an analogy to the perfection of the Trinity, ternary meters were referred to as perfect, binary as imperfect--you'll sometimes see that terminology.

Here are two playful applications of numbers in the base 3 - also known as the ternary number system.
However, if the counterweights are allowed to be placed on either pan, then the answer is 40, using weights of 1, 3, 9, and 27 ounces.
Then I placed the 12 coins on the pans in such a way that, if any one of them turned out to be counterfeit and heavy, the outcome of the weighing would be a positive number in balanced ternary notation.

 Cantor Set (PRIME)
When a number is written in base two it is said to be in binary notation, and when it is written in base three it is said to be in ternary notation.
But this must be as many as there are real numbers in the unit interval – for consider: we may represent all the real numbers between 0 and 1 in binary, and this is just every possible decimal with a 1 or a 0 in each decimal place.
The idea is evident: for every number whose ternary decimal expansion consists entirely of 0’s and 2’s, match it with the corresponding number whose binary decimal expansion has 0’s in the same place, and 1’s wherever the ternary number had 2’s.

In balanced ternary, where 2-trits represent -1 values, this is the negation operation.
We cut off before 8 because octal notation is the smallest base used to facilitate human-to-machine communication, and this seems quite contrary to the basic principles behind INTERCAL.
The small data types hold 16 bits, 10 trits, 8 quarts, 6 quints, 6 sexts, or 5 septs, and the large types are always twice this size.
