​The Loom as a Computer: Unpacking African Algorithms


​The Loom as a Computer: Unpacking African Algorithms

​The Kente cloth from Ghana to the untrained eye, it's a beautiful, intricate fabric. To a computer scientist, it's a living archive of algorithms.

​Every thread in a Kente loom makes a binary choice: over (1) or under (0). The master weaver follows a complex, unwritten algorithm that dictates patterns of repetition, variation, and recursion. This isn't just art; it's a precise set of instructions, a "code" that generates a stable, yet infinitely adaptable, design.

  • ​Fractal Logic: Just like a fractal image contains smaller versions of itself, Kente patterns embed smaller, self-similar motifs. This fractal logic is the backbone of modern data compression (JPEG, MPEG) and intricate CGI graphics.
  • ​Modular Self-Similarity: African social structures and village layouts often mirror this. A family unit's logic scales up to the village, and the village's logic scales up to the kingdom. This makes the entire system incredibly resilient and capable of indefinite replication. If one part changes, the whole doesn't collapse; it simply adapts, like a self-healing organism.

​Beyond the Grid: Sustainable Design for a Future-Proof World

​This isn't just about ancient history; it's about our future. As the West grapples with the environmental consequences of linear, consumptive growth, we're looking to the very "primitive" models we once dismissed:

  • ​Green Architecture: Modern architects are studying the natural cooling systems of Zimbabwean termite mounds – complex fractal ventilation networks – to design buildings like Harare's Eastgate Centre, which uses 90% less energy for cooling.
  • ​Computer Science Education: Programs like Culturally Situated Design Tools (CSDTs) teach coding to students by having them generate African patterns. They learn loops, variables, and conditional logic by creating Kente, not by building abstract calculators.
  • ​Resilient Urban Planning: Instead of rigid city grids, planners are exploring the self-organizing, recursive growth patterns of traditional African settlements to design sustainable, adaptable cities that grow organically with their populations.

​The "Living Archive": An Immortal Code

​What Western observers saw as unchanging, un-progressing societies, modern science now recognizes as systems designed for ultimate stability and resilience. The "code" of the culture—its math, its history, its social laws—was woven into the patterns, sung into the stories, and built into the very structures of daily life. This made the information incredibly robust, able to survive upheaval, transmit across generations, and "replicate itself indefinitely." The physical manifestation might wear out, but the mathematical soul lives on.

​This profound realization doesn't just decolonize history; it re-codes our future. By understanding that "primitive" often meant "hyper-efficient," we can unlock a wealth of knowledge that offers sustainable solutions to the challenges of our modern world. It's time to stop looking for progress only in the new, and start recognizing the advanced wisdom in the old.

From Harlem to Dakar to St. Louis: The WikiExplorers go to the St Louis Jazz Festival

WikiExplorers go to Senegal, a children’s story for ages 10–12, to learn about their shared history in music.  From Harlem to Dakar to St. Louis: The WikiExplorers Travel to Senegal   Ten WikiExplorers sat in a circle on the classroom floor in Harlem, laptops open, backpacks half-zipped, and ready to fly across the Atlantic Ocean to Dakar, Senegal.  “Dakar is right here,” said Amina, pointing at the map on her screen. “And St. Louis is way up north,” Malik added. “It used to be the capital of Senegal!” They were traveling to Senegal to attend a jazz festival in St. Louis, a city known for its music, rivers, and beautiful old buildings. Their assignment was special: learn about the shared history of African and African American music, find knowledge gaps on Wikipedia, and help fill them—with words, photos, and interviews. None of the children had ever been to Africa before. But Africa didn’t feel far away. Research Before the Journey Before the trip, the WikiExplorers met ...

Edgar Cayce’s prophecy and African Americans

  Edgar Cayce, sometimes called the “Sleeping Prophet,” gave thousands of psychic readings in the early 20th century. Much of his work focused on health, spirituality, and esoteric subjects like Atlantis, but in his life readings he also spoke about the destiny and role of various groups of people in history—including African Americans. Cayce’s prophecy and his views as they relate to African American history: 1. Spiritual Destiny of African Americans Cayce suggested that African Americans carried a deep spiritual mission. He often spoke of “souls” incarnating in different races and regions to fulfill certain purposes. About Black people in America, he indicated that they held a role in bringing balance, humility, and spiritual renewal to a world overly focused on materialism. He stated that African Americans would play a key role in the spiritual awakening of America . He connected their history of suffering and resilience with a kind of spiritual refinement—what he descri...

An educational children’s story designed for ages 9–12 about a group of curious kids called the WikiExplorers , who take on a Wikipedia research assignment and discover the story of David Blackwell and his surprising connection to AI and NVIDIA . The WikiExplorers and the Brilliant Mind of David Blackwell Written for Young Readers | Ages 9–12 Once a week, in a quiet corner of the school library, a special group of kids gathered. They called themselves the WikiExplorers—because their mission was to explore, discover, and share knowledge with the world by editing real Wikipedia articles. The club had five members: Zora, the thoughtful writer Miles, the math genius Kai, the tech whiz Luna, the fact-checker Tariq, the big-picture thinker One Friday afternoon, their club advisor, Ms. Ocampo, arrived with a special assignment. “Today, WikiExplorers,” she said, placing a stack of printouts on the table, “you’re going to add new information to a Wikipedia article—about NVIDIA, the computer c...
