Royal Museums Greenwich

Maury's chart described the behavior of the ocean and the atmosphere.

An 1852 Maury chart, which is currently owned by the Royal Museums Greenwich, records wind and current directions along ship tracks, distinguishes observations by season, and includes magnetic variation and sea temperature.

This essentially added another dimension to navigation.

Instead of seeing the ocean as just empty space between continents, sailors could now visualize it as a dynamic system.

They are so helpful with this, especially because a language like Danish is very tied to the North stuff we got some of this from.

And the other one is the Royal Museums Greenwich in England.

I have not been there.

I weirdly have been to the Greenwich Dateline, and I think we poked through the museum.

That was co-written by astrophysicist Heather Cooper and astronomer Nigel Henbest.

Heather Cooper has passed away, but the text lives on.

And then tons of digital museum resources were the other big sources this week, especially the Viking Ship Museum that is in Hrashkilde in Denmark, also the Royal Museums Greenwich in England, the Smithsonian National Museum of the American Indian, particularly helpful for Mayan calendar systems.

the Metropolitan Museum of Art for Egyptian calendar making, and many other sources for others too.
