Beautiful map for Mexico from a notable American mapmaker, Colton. But there's an interesting notation north of the border, showing the territory of Arizona as it ran east-west along the border, with New Mexico above it. #map #maps #Mexico #arizona

I always find it amazing that in bygone epochs how much travelling human beings partook in. They did not have access to modern technology; but, nonetheless were able to traverse thousands of miles on rudimentary forms of transport.

The 16th and 17th centuries constituted a period of drastic change in the way humanity conceptualized and sought to understand the world. Scholars made massive leaps in fields such as mathematics, astronomy, chemistry, and, perhaps most notably, physics. Arguably, no city contributed more profoundly to that new understanding than Cambridge." humanprogress.org/centers-of-p @histodon @histodons

"Who was the first person to reach the north pole? According to American adventurer Frederick Cook, it was him.
