Happy birthday to British #engineer, #mathematician, #physicist & #inventor Hertha Ayrton (1854-1923). I’ve shown her in my #linocut with a diagram of the dividers from her 1st of 26 (!) patents, one of her diagrams about the origin & growth of ripple marks & one of her diagrams of an electric arc lamp (a subject on which she literally wrote the textbook).⁠

Born Phoebe Sarah Marks, she was the 3rd of 8 children 🧵

Linocut portrait of Hertha Ayrton, surrounded by her diagrams and some of her inventions, printed in a gradient of red to purple. Ayrton, a middle age woman with a lot of curly hair, stands with her fingertips on a tabletop, looking right, in a loose dress. Her dress is red and colours change radially out to purple. To her left and above her are a series of horizontal sections showing the formation of ripples on a beach. Above her to the right is a diagram of her dividers from her patent. To the lower right is a cross-section of an arc-lamp.

A career civil servant in Nanyang, Heng was also an #astronomer, #mathematician, #seismologist, hydraulic engineer, #inventor, geographer, cartographer, ethnographer, artist, #poet, philosopher, politician & literary scholar. He was a bit of a controversial figure politically, sparing over calendar reform & with rivals amongst the palace eunuchs. But both his poetry & famous inventions are still remembered. He also improved the Chinese approximation for pi & 🧵2/n

Aloha! 🌈💐

I just took, on my way from Kona to Hilo, Hawai'i.

I started programming computers 40 years ago. Got a degree in Computer Science. I'm interested in a wide range of subjects.

Love word play, puns, poems, stories, and #books in general.

Have a sense of humor that's very eccentric and spicy.

Introverted. Love #Nature, solitude, #meditation, camping, hiking and #ocean frolicking.

Excited about using #technology to improve people's lives in a tangible way.

Hello everyone, finally sharing my #introduction with you all. If you read this, please say hello! Some fun facts about me:
- I’ve enjoyed a very rewarding career as an #inventor and #founder of #DeepTech #startups. Nowadays I help other entrepreneurs do great things.
- I was called a #HEPAMilitant and blocked by NB’s education minister, for offering to build #CRBoxes for classrooms.
- I’m a big music fan and was at the Horseshoe Tavern in #Toronto when the Stones played a secret gig there.
