factors that facilitated the development of science in ancient egypt
Ancient Egyptian technology Significant advances in ancient Egypt during the dynastic period include astronomy, mathematics, and medicine. Their geometry was a necessary outgrowth of surveying to preserve the layout and ownership of farmland, which was flooded annually by the Nile river. The 3,4,5 right triangle and other rules of thumb served to represent rectilinear structures, and the post and lintel architecture of Egypt. Egypt also was a center of alchemy research for much of the western world.
Ancient Egyptian race controversy Since the second half of the 20th century, most anthropologists have rejected the notion of race as having any validity in the study of human biology.[17][18] Stuart Tyson Smith writes in the 2001 Oxford Encyclopedia of Ancient Egypt, "Any characterization of race of the ancient Egyptians depends on modern cultural definitions, not on scientific study. Thus, by modern American standards it is reasonable to characterize the Egyptians as 'black', while acknowledging the scientific evidence for the physical diversity of Africans."[19] Frank M. Snowden asserts "Egyptians, Greeks and Romans attached no special stigma to the colour of the skin and developed no hierarchical notions of race whereby highest and lowest positions in the social pyramid were based on colour."[20][21]
