http://terpconnect.umd.edu/~tlaloc/archastro/ae26.html

Extractions: by Jose Barrios Garca In the 14-15th centuries Grand Canary and Tenerife were inhabited by Berber populations, called Canarians and Guanches. They presumably came from the nearby continent on different occasions between the first millennium BC and the first millennium AD. These populations remained relatively isolated until the European rediscovery of the Islands in late 13th century. At this time the population of each Island was about 40-60,000 inhabitants, sustaining a developed agricultural (barley, wheat) and stock raising (goats, sheep, pigs) economy. Written sources from c. 1300 AD on certify the arithmetical and calendrical activities of these groups. On this basis, I started the research on the mathematical and astronomical practices of these people that crystallized into my doctoral dissertation (editors note: congratulations to Jose for his recent defense of thesis at the University of La Laguna, Tenerife). For each Island the study considered: 1) the economical, social, political and religious organization of the Island 2) the written and archaeological evidence regarding numerical and calendrical activities 3) the economic and cultural context of the number systems and the calendars.

THE NASHVILLE NUMBER SYSTEM In the late 50's, Neil Matthews devised a musical number system for the Jordanaires to use in the studio. Charlie McCoy and fellow studio musicians began adapting Matthews' number system into chord charts. The Nashville Number System has evolved into a complete method of writing chord charts and melodies-combining Nashville shorthand with formal notation standards. The Nashville Number System is 130 pages with a step by step method of how to write a Nashville number chart for any song. Included with each NNS book in Edition 7 is the cd, "String Of Pearls" . This is a 10 song cd of instrumentals, including, Amazing Grace. I walk you through the details of each song and explain the Number System tools used to write the charts. Now, while listening to the cd, you can see and hear how Nashville number charts work. 7th EDTION NOW AVAILABLE AT A GREAT PRICE! The 7th Edition of the "Nashville Number System" by Chas Williams is now available! More great charts, an Interactive CD, updated content!

13. A Tutorial On Binary Numbers
As you know, the decimal system uses the digits 09 to represent numbers. If we wanted to put a larger number in column 10^n (e.g., 10), we would have to

Extractions: A pretty damn clear guide to a quite confusing concept by Christine R. Wright with some help from Samuel A. Rebelsky. To understand binary numbers, begin by recalling elementary school math. When we first learned about numbers, we were taught that, in the decimal system, things are organized into columns: such that "H" is the hundreds column, "T" is the tens column, and "O" is the ones column. So the number "193" is 1-hundreds plus 9-tens plus 3-ones. Years later, we learned that the ones column meant 10^0, the tens column meant 10^1, the hundreds column 10^2 and so on, such that As you know, the decimal system uses the digits 0-9 to represent numbers. If we wanted to put a larger number in column 10^n (e.g., 10), we would have to multiply 10*10^n, which would give 10^(n+1), and be carried a column to the left. For example, putting ten in the 10^0 column is impossible, so we put a 1 in the 10^1 column, and a in the 10^0 column, thus using two columns. Twelve would be 12*10^0, or 10^0(10+2), or 10^1+2*10^0, which also uses an additional column to the left (12). The binary system works under the exact same principles as the decimal system, only it operates in base 2 rather than base 10. In other words, instead of columns being

http://www.michielb.nl/maya/math.html

Extractions: michielb.nl projects maya astronomy / geographical orientation Instead of ten digits like we have today, the Maya used a base number of 20. (Base 20 is vigesimal.) They also used a system of bar and dot as "shorthand" for counting. A dot stood for one and a bar stood for five. In the following table, you can see how this works. Because the base of the number system was 20, larger numbers were written down in powers of 20. We do that in our decimal system too: for example 32 is 3*10+2. In the Maya system, this would be 1*20+12, because they used 20 as base. Numbers were written from bottom to top. Below you can see how the number 32 was written: 20's 1's It was very easy to add and subtract using this number system, but they did not use fractions. Here's an example of a simple addition: 8000's 400's 20's 1's As you can see, adding is just a matter of adding up dots and bars! Maya merchants often used cocoa beans, which they layed out on the ground, to do these calculations. If you have a Java-enabled browser, you will see an interactive number converter below.

Extractions: Department of Mathematics College of Science University of Utah On one level this page defines the words we use to distinguish among different types of numbers. However, it also sketches the logical construction underlying the system. This illustrates one of the fundamental principles in doing mathematics. Introduce concepts in a simple context and then generalize them in such a way that rules and facts that are true in the simple context remain true in the more general context. The natural numbers are We can add or multiply two natural numbers and obtain another natural number. However, the difference or the ratio of two natural numbers is not always a natural number. For example, and are natural numbers, but and are not. More general sets of numbers can be thought of as being constructed to make operations always possible that the more restricted set of natural numbers does not allow. We want to do this in such a fashion that the usual rules of arithmetic remain true. These include, for example: a + b = b + a The commutative law of addition.

Extractions: Home What All Libraries Have Page 4 of 15 Libraries use classification systems to organize the books on the shelves. A classification system uses letters and/or numbers (call numbers) to arrange the books so that books on the same topic are together. This arrangement results in "serendipitous browsing:" you find one book in the catalog, go to the shelf, and, an even better book is sitting right next to it. Libraries in the United States generally use either the Library of Congress Classification System (LC) or the Dewey Decimal Classification System to organize their books. Most academic libraries use LC, and most public libraries and K-12 school libraries use Dewey. Book title: Uncensored War: The Media and Vietnam
