Africa Infographic – By Kai Krause

The size of Africa as a landmass is greatly underestimated. This is due in part to the proportions used on the Mercator map. The Mercator map is the map that is most commonly used and tends to skew the view of the world’s landmasses, which has led to misrepresentations of the size of countries and continents. The issue with the Mercator Map is not Africa’s size on the map. Its size on the Mercator map is proportionally accurate. Because the map lays out the landmasses of the world across a circular/cylinder-like area. This causes the areas closest to the “poles” to be elongated/stretched. Africa overlays the Equator so it’s size proportions change only minimally while the size of other continents/countries is inflated.

Ishango Bones

 

The Ishango Bone is likely one of the oldest mathematical tools in existence. Sources differ regarding the date of its discovery with some indicating that it was discovered in 1950 while others site 1960 as the date of discovery. The bone was found amongst the ruins of a settlement near Lake Edward that was buried after a volcanic explosion. The Ishango Bone was discovered by geologist, Jean de Heinzelin de Braucort (1920-1998) in the Ishango region of the Democratic Republic of Congo. The bone is believed to be the fibula of a baboon. It measures approximately 10cm-14cm in length and is inscribed with a organized series of notches. At one end of the tool is a sharp quartz edge that is believed to have been used as a writing instrument. The Ishango Bones discovered by Heinzelin de Braucourt are housed at the Royal Belgian Institute of Natural Sciences. Continue reading “The Ishango Bone: Early Tool Used For Mathematic Computations”
