Ships, Sea and the Snark

  
A whatsapp map created for refugees,
presented by Professor Marie Gillespie,

in which distances are measured in money.

 This week's episode of Ships, Sea & the Stars from the Royal Museums Greenwich might be the the ships-sea-and-the-starriest one yet, because it deals with navigation. Not just the treasures of cartography, but the Pacific star maps being recommitted to memory by modern Hawaiians like Nainoa Thompson - an account of which you can hear me reading at 5:25 - and the Global Positioning System, or GPS, originally reserved for the American military until it was unscrambled for general use in January 2000. Other systems are now available of course, just not the EU's, because we're leaving it. On a completely unrelated-to-Brexit note, I also get to rattle through some Hunting of the Snark at 34:30. 

"Other maps are such shapes, with their islands and capes!

   But we've got our brave Captain to thank

(So the crew would protest) "that he's bought us the best—

   A perfect and absolute blank!"  (Source.)

 Marie Gillespie also brings a bag refashioned by a refugee solidarity network on Lesbos from one of a million lifejackets now left on the beaches of Greece, and if you fancy further clicks Extra Credits just produced a nice series on Austronesian navigation which you can watch here, and you can give to the Refugee Council here.
