Poor nutrition and illness in childhood limit human growth. As a consequence, the average height of a population is strongly correlated with living standards in a population. This makes the study of human height relevant for historians who want to understand the history of living conditions.
Because the effect of better material living standards is to make people taller, human height is used as an indirect measure of living standards. It is especially relevant for the study of living conditions in periods for which little or no other data is available — what historians refer to as the pre-statistical period.
It is important to stress that height is not used as a direct measure of well-being. The variation of height within a given population is largely determined by genetic factors.1
The history of human height allows us to track progress against undernourishment and disease and makes it possible to understand who started to benefit from modern advancements and when.

Isochrone maps visualize areas reachable within the same travel time from a starting point (e.g., “30 minutes by car from Geneva”).
Advanced tools allow you to:
• Combine multiple isochrones (e.g., overlap a 60-minute zone from Geneva and a 30-minute zone from Yverdon).
• Filter results to show only areas meeting all criteria.
Pre-Columbian civilizations refer to the societies and cultures that thrived in the Americas before the arrival of Christopher Columbus in 1492. These civilizations, including the Maya, Aztec, and Inca, developed advanced knowledge in architecture, astronomy, agriculture, and governance, leaving a lasting impact on history despite their decline following European colonization.

The website OurWorldInData.org gathers at lot of statistics from reliable sources (United Nations, WHO, World Bank…) in order to alert and make progress against the world’s largest problems.
Many projections of the globe have been published over the centuries, despite the mathematical impossibility of a rectangular projection. There is then a heated debate about which is the most accurate. Impossible question of course as it depends on which parameter you value the most: angles, areas or distances. There is no way to be accurate on one parameter without changing another incorrectly.
Here are some pages to help to better understand the differences between the different projections available:

On the heels of the History channel special that explored what Earth might be like if the human race were suddenly to disappear comes a series that provides, in even-more detail, a picture of a post-human future, revealing the fate of structures like the Sears Tower and the Sistine Chapel and creatures that might inherit the places we once lived. Supporting the visuals and special effects are interviews with specialists from the fields of engineering, botany, biology, geology and archaeology.
