4.1 Africa — The Invisible Threads

The Invisible Threads: How Africa Wove the Foundations of Computing That Colonialism Tried to EraseThere exist transmissions that official history refuses to see. Threads of knowledge running beneath the surface of dominant narratives, invisible but never broken.In 1884, fourteen European powers partitioned Africa in Berlin as one might cut up a fabric — with no regard for the patterns already woven into it. Epistemicide accompanied colonization: systematic destruction of a people's knowledge to impose a foreign system of understanding.And yet, not all threads were severed.The Ifa system of the Yoruba rests on two hundred and fifty-six figures, each composed of eight positions taking two states — open or closed. Two states. Eight positions. We have just described exactly a computer byte. The associated literary corpus contains more than four hundred and thirty thousand verses, classified according to these categories. A database, a memory addressing system — centuries before the computer.The ethnomathematician Ron Eglash traced a troubling lineage: from Ifa to Arabic geomancy, from geomancy to European alchemists, from alchemists to Leibniz himself. The mathematician who formalized binary corresponded with missionaries who described these African traditions to him.You will discover African fractals in architecture, textiles, and hairstyles. The Timbuktu manuscripts hidden in attics during colonial occupation. Benjamin Banneker predicting eclipses and building a clock entirely from wood. Shelby Davidson inventing an automatic postal rate calculation device in 1911.Binary was not born in a European laboratory. It may have traveled from the forests of Nigeria to the salons of Hanover.The invisible threads were never broken. They await recognition.
