Want to hear a story abt Jewish astrolabes?

An #astrolabe is an astronomical instrument for various calculations, superseded by clocks, calculators, computers

But the astrolabe built the world as we know it & Jews played a key role in transferring this knowledge across cultures
The 14thcen Iberian astrolabe pictured above, w/ Hebrew lettering, was chosen by the @BBC for its History of the World in 100 Objects

You can see much more detailed info & images of it here: britishmuseum.org/collection/obj…

There's robust scholarship on these

bbc.co.uk/programmes/b00…
A mashup of Greek technologies, knowledge of the astrolabe wends its way, as with much ancient thought, into Syriac & Arabic then sometimes via Hebrew and/or European vernaculars into Latin.

Astrolabe is a Grk word transliterated in Arabic, Persian & Hebrew, at times translated

1/n I'm beyond thrilled to announce that @RaygunIcecream has asked me to lead one of the books for #RoamBookClub3 along with @beauhaan;

Your team is currently hard at work designing what we believe will be an extraordinary 6 week learning experience for our beloved #roamcult -->
2/n There will be 2 groups working side by side - Beau will lead a discussion of Ahrens' "How to Take Smart Notes" and I'll lead, for returning members, "The Culture Code" by Dan Coyle.

My group will have a limited number of spots. Beau's group will not be size-limited.
3/n if you are unable to join the Coyle group (enrollment has to be capped, sorry) don't worry; you can still follow along; my plan is to live tweet + carry our discussion out to Twitter

Furthermore, the plan is to bring you more "episodes".

This is just the beginning!
