Scottish-born inventor Alexander Graham Bell — who died #onthisday in 1922 — goes to kiss his wife Mabel while she stands in one of his spectacular tetrahedral kites. See more of these wonderful creations (and the kiss realised) in our post here: https://publicdomainreview.org/collection/alexander-graham-bell-s-tetrahedral-kites-1903-9 #OTD
@publicdomainrev Huh nice - are these actually Sierpinski Tetrahedrons or is the main triangle higher up, from this photo it sure looks like it:

some company back in the mid 70's used to sell a plastic tetrahedron that you had to buy multiple kits to get to that size.. I did so and made the mistake of using twisted line in place of braided.. & one day soon after building, we started flying on a nice spring day in south OKC, that soon turned dark and stormy & the damn line broke while we were hauling it down...don't know where it flew to with 500ft of line acting as a stabilizing drag..
Mabel inside of a tetrahedron made of smaller tetrahedrons, leaning forward to kiss Alexander. The image is labeled, "318 taken 1903 at 16/17" in a scrawling hand.
@publicdomainrev This almost certainly happened at Beinn Bhreagh, where Bell had a workshop...there is a very good museum nearby Baddeck with lots of Bells inventions on display including Hydrofoils and some of these beautiful kites.

@futurebird @publicdomainrev @RachelThornSub coincidentally I just learnt the same thing from the local science museum (https://www.rijksmuseumboerhaave.nl/)’s Dutch Sign Language tour (https://izi.travel/nl/5048-rijksmuseum-boerhaave-gebaren/nl#/browse/a5f77f36-5cde-4944-b99b-3ee56a04b967/nl , item 36)
@futurebird @outer @publicdomainrev
also, upon cofounding the company that would become AT&T, granted virtually all of his shares to his wife.
@futurebird @publicdomainrev @RachelThornSub Thank you. Just great!
@publicdomainrev this is very sweet
