432 Centuries of Recorded Science and Technology in Black Africa

Abstract During the 1970s and 1980s, American and European investigators discovered evidence of such African scientific achievements as the following: (1) the domestication of assorted plants in The Egyptian Nile Valley ca. 18000 BP ; and domesticated cattle in the Kenyan Highlands, ca, 15000 BP . These were achieved thousands of years before plant and animal domestication in South west Asia, the hitherto presumed place where domestication first occurred; and (2) the making of Carbon steel in Tanzania, in the 1st c. BC , using techniques the discoverers called “semi-conductor technology – the growing of crystals”. These and other records of advanced scientific achievements, and at such dates, should prompt a profound revision of our understanding of the scientific knowledge developed by pre-20th century Africans before Europeans conquered and colonized and shattered African societies. They should also prompt a revision of the history of science in the world. In this article I shall present 13 exhibits drawing from the history of spectacular African achievements in science and technology. They range in time from ca. 43200 BC to 1952 AD . And they cover, geographically, Lesotho in Southern Africa; to Kenya, Uganda and Tanzania in East Africa; to the Democratic Republic of the Congo in Central Africa; to Egypt in North Africa; and to Liberia and Nigeria in West Africa.
