Now that's an amphora I can get behind, literally.

Here, enjoy some Minoan ruins I stumbled across...

Apropos of nothing, is anyone else here as big a fan of Indie: Fate of Atlantis as me? (*)

(*) i.e., old

O-Ton Martin Luther
Ihm ging es wohl beim Übersetzen der Bibel nicht besser als so manchem zeitgenössischen Autor, und man kann sich vorstellen dass er auf der Wartburg auch ziemlich an Bewegungsmangel litt...

Our student built balloon SSTV electronics are still *super* glitchy, but we managed a few rounds testing with local hams

Mating system Males of this species offer a nuptial gift to potential female mates. Some Pisaura mirabilis specimens have also been observed to use thanatosis during courtship.[12] After presenting the nuptial gift to the female, she bites on to the gift and the male moves to her epigyne to deposit sperm with his pedipalps. Throughout copulation, the male keeps a leg on the gift so as to be ready if she tries to escape with it or attack him. At this time, the male may feign death – his limbs become straight and he is dragged along with the female while holding on to the gift. When the female stops, the male slowly "resurrects" and continues attempting to mate.[12] Thanatosis in P. mirabilis has been observed to significantly increase the male's odds of successfully copulating from less than 30% to 89%.[12][13]

Anyone wants some triopses? We left some sand from the aquarium in a bucket outside and now they hatched and seem to go through an entirely unplanned population explosion!

Revisiting this and accompanying lectures for project ideas, and it is just such a joy and thing of beauty. They clarity and accessibility with which rich phenomena are extracted from seemingly simple or not so simple equations is jist exemplary.
