Africa in the middle ages had many achievements that we use today. The baffle which later turned into a crane was use to raise obelisks, but now days we call it a crane and we use it to build buildings. The Africans in the middle ages also made copper and bronze chisels which helped them chisel stone to make statues and buildings. But today we still use chisels for utilities like getting the glue off materials. Africans in the middle ages also made furnaces that have gotten so hot. Today we still use furnaces that heat our house. The Africans in the middle ages had navigation which led them to travel the seas but now days we still use navigation to travel seas. Africans also made boats which let them travel rivers and today we still use boats but not the same boats to travel through rivers and boats. Africans started using salicylic which healed them and today we have advanced by making more medicines to heal more viruses. They also used formulas to calculate volume of shapes and today we still use formulas exactly like the middle ages to calculate volumes of shapes.
