How come nobody has noticed? The markings on the Ishango bone perfectly model a sieve for the prime numbers. It is observed (for n greater than 3) that the middle column M of the bone eliminates from the sequence n = 1,2,3,4,5,6,7,8,9,10, numbers composed of "copies" of others, leaving behind prime numbers only.

[☆N.B. A "sieve" in mathematics is an algorithm or process for picking out prime numbers from the procession of natural numbers].

Eurocentrism vs Afrocentrism
Eurocentrism vs Afrocentrism Kamjiverse 69 Views • 3 years ago

Dr. Rebecca Futo Kennedy presents on the Antiquity and Middle Ages Channel on the differences between Afrocentrism and Eurocentrism.

Join us in this thought-provoking video as we delve into the contrasting ideologies of Eurocentrism and Afrocentrism, exploring their impact on our understanding of history and culture. Eurocentrism, a widely dominant view, emphasizes the achievements and contributions of European cultures, often overlooking the perspectives and contributions of other cultures. Afrocentrism, on the other hand, focuses on centering and celebrating African history, culture, and achievements, challenging Eurocentric narratives that have historically marginalized Africa and its diaspora. We delve into the historical context that shaped these perspectives, examining the legacy of colonization, slavery, and the struggle for cultural recognition. Eurocentrism tends to portray European history as the pinnacle of human progress and often ignores or minimizes the contributions of non-European civilizations. Afrocentrism seeks to rectify this by highlighting the rich history and achievements of African civilizations such as Ancient Egypt, Mali, and Great Zimbabwe, showcasing their impact on world history and culture. We explore how Eurocentrism has influenced academia, education, and media, often shaping our understanding of world events and perpetuating stereotypes and biases. Afrocentrism challenges this narrative, striving to reclaim and center African perspectives, voices, and experiences. The video examines the ways in which Eurocentrism and Afrocentrism have influenced art, literature, and social movements, shaping cultural identity and promoting inclusivity. We discuss the importance of recognizing and embracing multiple perspectives, fostering a more balanced and nuanced understanding of history, and appreciating the diverse contributions of different cultures. Join us as we engage in a respectful exploration of these contrasting ideologies, aiming to encourage dialogue, understanding, and the celebration of cultural diversity in a global society.
