Legend
I heard a story about a female academic giving a paper at the IHR who, after receiving a long and aggressive question from a senior male professor, simply leaned back with her hands behind her head and replied “Oh, do fuck off.”
One of my colleagues went to a seminar at Berkeley and when someone asked a question Derrida brushed it off saying ‘what you ask may be important but it is not interesting’.

Fantastic outcomes! Finally mathematically talented girls and young women are getting what boys and young men have had, and taken for granted, for centuries: multiple mentoring, role models, endless positive reinforcement, recognition, approval, and confidence-boosting, the list goes on and on
How can we flip the decline in girls and gender-diverse students doing mathematics at higher levels?

Built by the engineers of the #Sydneyharbourtrust c1920 under Chief Engineer #hdwalsh, it was the last of the great finger wharves they built. #publicsydney

Had a terrific Friday evening walk & shop! Bought a beautiful spotted shirt at Vinnies! Took it home, tried it on.

Erm... sometimes, there is a good reason why someone sends a clo to the charity shop bin. Oh well. It was fun browsing the bric-a-brac anyway.

Confession time: The main reason for my trip wasn't to visit Blackpool. It was a pilgrimage to Preston for a visit to the brutalist bus station. It didn't disappoint.

I enjoyed this thoughtful conversation with English professor Wesley Beal. Asking big questions doesn’t have to be limited to the humanities.

Prescient. When humans finally cause our own extinction, through warfare and climate destruction and stupidity, the Earth, if it could talk, will say: "Phew, thank god they're gone, they were really becoming a bloody nuisance, effing ruined the whole works. Time I gave the dinosaurs another whirl."
As a consequence L believed that, like classical physics, geological dynamics are ergodic. In exploring a Newtonian state space, the earth system will return to a state in which iguanadons, ichthyosaurs, and pterodactyls roam the earth

Correction: Calculus was first developed in the 15th C by Madhava and the Kerala school in India and published in the Yuktibhāṣā, two centuries before Newton and Liebniz. The chain and timings of the transmission of Kerala calculus to Europe are gradually being fleshed out and verified

Want to know why your mobile phone photos of the Moon look like crap?

I have a new @aunz.theconversation.com article explaining why, how you can take better(ish) photos, and what astronomical sights your phone can photograph well.

Why is it so hard to take a good photo of the Moon with my phone?
Phones can often take great photos, but why photos of the Moon typically disappointing? The Moon itself and camera design are both part of the answer.

It got more exciting as we got very close to the working steam engine. Not sure I have ever seen a centrifugal governor in operation before. Apparently it wasn't working quite correctly today, and small changes in piston speed affect the quality of the weave. Fascinating.
