Who's a handsome brown banksia then? Proudly guarding University Avenue, these soft brush inflorescences are subtended by brown velvet bracts, just like my Auntie C's old verandah sofa. @ourANU

There is more seat leg room on a @linkairwaysau Saab 340B than on an A380, plus the turboprop engine vibrations transmitted through your seat ensure you get a free back massage!

This railway station should definitely employ a Station Cat. The position appears to be vacant

Ghana's Maths Queen @angela_tabiri is the first African to win The Big Internet Math Off competition.
She's on a quantum mission to mentor girls and hopes her 2024 win will encourage more African women to take the subject.

A tiny brass 2-cylinder Shay is under construction. So far, just the underframe and engine. Can't wait to see it in steam!

And it's in steam! Watch, just watch, sound on!
Tracks? That is a very good question. 45mm gauge needed.

At last the tiny Shay has tracks to run on! What a weird little contraption!
Now for some wagons and switches and sidings and signals and all sorts of whatnots...

For your weekend relaxation: 1.8 billion years of plate tectonics in 72 seconds.
Fun to locate your hometown (or ancestral town) and track where it's been over the years...or how long it's even existed as a physical location.
