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.

True, that. Higher education was well-developed and systematic in pre-colonial Australia
Higher education predates the printing press. Believe it or not, teaching is about more than “information” that a technology can “deliver instantly”
Wow. Just wow.
"Students pay premium prices for information that AI now delivers instantly and for free. A business student can ask ChatGPT to explain supply chain optimization or generate market analysis in seconds. The traditional lecture-and-test model faces its Blockbuster moment."
