African Unit 3
Practical Fractal African Algorithms
Name: Penelope Stickney College: Kankakee Community College Discipline: Humanities Module Title: “Practical Fractal African Algorithms” Narrative Description of the Module: Fractal structure and design is not a new, computer-generated concept but one historically represented in indigenous cultures. This module explores fractal designs found in African villages and the strip-woven cloth patterns of the Ewe people of Ghana and Togo. Application of the woven cloth includes a study of symbols, color, and messages. Project outcome: Within the curriculum, fractal experiments are applied to other complex African designs including ancient African sculpture. Contemporary examples include fractal design in hair braiding and demonstrate pattern continuity in modern African architecture.
Educational Objectives of the Module
- Interpret cultural and geographical history of the Asante people of Ghana
- Learn the use of similar patterns, or fractals, as found in traditional African settlements
- Recognize the application of fractals in African rhythms and color in Kente cloth designs

- The Ashanti Kingdom (Ghana)
- The Akan peoples who made up the Ashanti kingdom are the best-known ethnic group in Ghana, comprising around 2 million of the country’s 12 million inhabitants. All of the Ashanti kings belong to the Oyoko Dako clan, the clan of chieftains; they are the ones who have created and strengthened the Ashanti nation. This program shows the Ashanti kingdom: it explains the strict hierarchical organization of the village, the importance of the characteristic kente garment, the naming of children, the Ashanti religious beliefs, the importance of traditional values and traditional festivals, and the protocol surrounding the paramount chief of the Ashanti. (14 minutes)
- Wrapped in Pride: The Story of Kente in America
- America Once reserved for African royalty, kente cloth has become a familiar pattern in American culture. Narrated by Tony Award-winning actress Ann Duquesnay, this program traces how kente cloth crossed the Atlantic from the West African Republic of Ghana at the beginning of the civil rights movement to literally become part of the fabric of American life. Film footage shows Ashanti and Ewe weavers making kente, while several scholars and experts discuss the cultural and political significance of this distinctive cloth. (27 minutes)
- The 300 Year Old Asante Kingdom (DOCUMENTARY)
- Akan People
- The Akan ( pronunciation ; /əˈkæn/) are a nation and indigenous ethnic group residing on the Gulf of Guinea in the southern regions of the Gold Coast region in what are today the republics of Ghana and the Ivory Coast in West Africa. This is a detailed account which includes a complete bibliography. Akans are the largest ethnic group in both countries and have a population of roughly 20 million people. The Akan language (also known as Twi–Fante) is a group of dialects within the Kwa branch of the Niger-Congo language family. Also included under the term "Akan" are the Bia languages (in which case it is common to speak of "Akan languages", as a group of languages).
- The Fractals at the Heart of African Designs
- Ron Eglash is an ethno-mathematician: he studies the way math and cultures intersect. He has shown that many aspects of African design — in architecture, art, even hair braiding — are based on perfect fractal patterns. Eglash states that the African “heritage is about mathematics and not just about singing and dancing.” TEDGlobal2007 (16:57)

- A fascinating exploration of how computer algorithms can be applied to our everyday lives, helping to solve common decision-making problems and illuminate the workings of the human mind.
- All our lives are constrained by limited space and time, limits that give rise to a particular set of problems. What should we do, or leave undone, in a day or a lifetime? How much messiness should we accept? What balance of new activities and familiar favorites is the most fulfilling? These may seem like uniquely human quandaries, but they are not: computers, too, face the same constraints, so computer scientists have been grappling with their version of such problems for decades. And the solutions they’ve found have much to teach us.
- In a dazzlingly interdisciplinary work, acclaimed author Brian Christian and cognitive scientist Tom Griffiths show how the simple, precise algorithms used by computers can also untangle very human questions. They explain how to have better hunches and when to leave things to chance, how to deal with overwhelming choices and how best to connect with others. From finding a spouse to finding a parking spot, from organizing one’s inbox to understanding the workings of human memory, Algorithms to Live By transforms the wisdom of computer science into strategies for human living.
- lbackstrom. The Importance of Algorithms. https://www.topcoder.com/community/data-science/data-science-tutorials/the-importance-of-algorithms/
- The first step towards an understanding of why the study and knowledge of algorithms are so important is to define exactly what we mean by an algorithm. According to the popular algorithms textbook Introduction to Algorithms (Second Edition by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, Clifford Stein), "an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values as output." In other words, algorithms are like road maps for accomplishing a given, well-defined task. So, a chunk of code that calculates the terms of the Fibonacci sequence is an implementation of a particular algorithm. Even a simple function for adding two numbers is an algorithm in a sense, albeit a simple one.
- Some algorithms, like those that compute the Fibonacci sequences, are intuitive and may be innately embedded into our logical thinking and problem solving skills. However, for most of us, complex algorithms are best studied so we can use them as building blocks for more efficient logical problem solving in the future. In fact, you may be surprised to learn just how many complex algorithms people use every day when they check their e-mail or listen to music on their computers. This article will introduce some basic ideas related to the analysis of algorithms, and then put these into practice with a few examples illustrating why it is important to know about algorithms.
- lbackstrom. The Importance of Knowing Algorithms
- As a computer scientist, it is important to understand all of these types of algorithms so that one can use them properly. If you are working on an important piece of software, you will likely need to be able to estimate how fast it is going to run. Such an estimate will be less accurate without an understanding of runtime analysis. Furthermore, you need to understand the details of the algorithms involved so that you’ll be able to predict if there are special cases in which the software won’t work quickly, or if it will produce unacceptable results.
- lbackstrom. Conclusion
- The different algorithms that people study are as varied as the problems that they solve. However, chances are good that the problem you are trying to solve is similar to another problem in some respects. By developing a good understanding of a large range of algorithms, you will be able to choose the right one for a problem and apply it properly.
- Kuchling, A.M. Background: Algorithms. https://fiftyexamples.readthedocs.io/en/latest/algorithms.html (Copyright 2012)
- An algorithm specifies a series of steps that perform a particular computation or task. Algorithms were originally born as part of mathematics – the word “algorithm” comes from the Arabic writer Muḥammad ibn Mūsā al-Khwārizmī, – but currently the word is strongly associated with computer science. Throughout this book we’ll examine a number of different algorithms to perform a variety of tasks. Consider: Algorithms resemble recipes. Recipes tell you how to accomplish a task by performing a number of steps.
- Does an algorithm actually exist to perform a given task?
- If someone proposes an algorithm to solve a task, are we sure that the algorithm works for all possible inputs?
- How long does the algorithm take to run? How much memory space does it require?
- Once we know it’s possible to solve a problem with an algorithm, a natural question is whether the algorithm is the best possible one. Can the problem be solved more quickly?
