World - Mollweide Projection

Mollweide's political planisphere centered on the America, showing the entire Pacific Ocean with its islands and the Atlantic Ocean. This cartographic projection, in which the Earth's globe is transformed into an ellipse of equivalent area, was developed by the German mathematician and astronomer Karl Mollweide.

Karl Brandan Mollweide (1774–1825) was born and raised in Wolfenbüttel, Lower Saxony, Germany. Mollweide taught himself calculus and algebra. He taught in Halle and Leipzig. In trigonometry, he rediscovered the formula now known as Mollweide's formula. He later developed a cartographic projection that bears his name. The Mollweide projection is a pseudocylindrical equal-area cartographic projection, commonly used for maps of the world or the celestial sphere.

Five of the world's six continents are widely and permanently inhabited. Asia is the most populous continent with about 60% of the world's population (China and India together account for over 35%). Africa comes in second with over 15%. America has about 14%. Europe has about 10% and Oceania less than 1%. The harsh conditions on Antarctica prevent any permanent habitation. Urban population is 57.5% of total population (2023). Ten largest urban agglomerations: Tokyo (Japan) - 37,393,000; New Delhi (India) - 30,291,000; Shanghai (China) - 27,058,000; Sao Paulo (Brazil) - 22,043,000; Mexico City (Mexico) - 21,782,000; Dhaka (Bangladesh) - 21,006,000; Cairo (Egypt) - 20,901,000; Beijing (China) - 20,463,000; Mumbai (India) - 20,411,000; Osaka (Japan) - 19,165,000 (2020).

Porto Seguro southern Bahia, Brazil, one of the best tourist destinations on the Brazilian coast. Porto Seguro was the site of Brazil's discovery by Europeans in 1500. The first European colony on Brazilian soil was also founded here in 1503, when the first church and later the first hospital in Brazil, the Santa Casa da Misericórdia, were built. Porto Seguro became the economic center of the Portuguese lands in America, during the brazil-wood (pau-brasil) boom until around 1530. At the time, the Portuguese were the world's greatest economic power and dominated trade along the entire east and west coast of Africa. In the early 16th century, the Portuguese expelled the Arabs from trade in the Indian Ocean, dominating the Persian Gulf and the European trade route through it.
