April 25 is #WorldPenguinDay so enjoy some Adélie penguins! ⠀


This handsome couple, two Adélie penguins (Pygoscelis adeliae), common to all the Antarctic coasts, are hand printed in black ink with a hint of orange on white Japanese kozo (or mulberry) paper. Each print is 12.5” by 9.25” (31.8 cm by 23.5cm). Adélie penguins are the most widely spread and southernly penguins (along with the Emperor penguins).⠀

Happy birthday to #mathematician Felix Klein (1849-1925). This is a hand-carved and hand-printed image of the famous mathematical object, the Klein bottle, printed in a gradient of pale yellow-green to darker blue-green on paper 8” by 8” (20.3 cm by 20.3 cm). First described by mathematician Felix Klein in 1882, this object has a single surface, rather like a 3D version of a Möbius strip. 🧵

It’s #InverteFest again! So here is my pollinator propaganda for Manufactured Ecosystems. Thinking about the future of pollination and seeking solutions from technological and nature-based knowledge. This is essentially my conclusion: we can aid our beleaguered pollinators with technology but their continued success is vital. We need to foster the insects to keep ecosystems functioning. 🧵

Born on this day: #physicist J. R. Oppenheimer (1904-1967). While best remembered for his role in the Manhattan Project, he was a giant of 20th century theoretical physics, nominated for a Nobel 3 times. ⁠

In 1927 he & Max Born greatly simplified how we predict electrons behaviour within atoms. The Born-Oppenheimer or adiabatic approximation is based on the observation that electrons are 1000s times lighter than nuclei, 🧵1/n
