contribution of egypt in the field of science
Ancient Egyptian technology The Ancient Egyptians had knowledge to some extent of sail construction. This is governed by the science of aerodynamics.[14] The earliest Egyptian sails were simply placed to catch the wind and push a vessel.[15] Later Egyptian sails dating to 2400 BCE were built with the recognition that ships could sail against the wind using the lift of the sails.[15][16] Queen Hatshepsut oversaw the preparations and funding of an expedition of five ships, each measuring seventy feet long, and with several sails.[dubious â€“ discuss][citation needed]Various others exist, also.
