This is why handwriting maths in front of students is so important. Typeset final versions make them feel there is no struggle or thinking around things.

It took a while, but I worked out how to make YouTube work on the television. However, the thing I wanted to see is Vimeo.

Latest royalty statement shows there are another 69 copies of A Stitch in Line out in the world, in people's hands. Thank you so much, and happy stitching!

Not sure what to make of the fact that the paragraph instructing my daughter to describe any use she had made of AI in her assignment contained an error that a spell-checker would have picked up.

The cat will not let me pat her, but at least she didn’t hiss at me, which is how she greeted me when I got home from Bridges last year.

Ms 19 and I took the chance to further our joint enjoyment of silo art by tracking down this off-trail singleton in Geelong.

Last year, I made feijoa jam with my father’s large crop. There was a lot of peeling. This year someone else gave me 1.5 kg of small feijoas, so I made a skin-on chutney. Couple of hours in the slow cooker, finished on the stove.

I'm on the hunt for a reference cited in a paper that is about 10 years old, and the author hasn't been super careful about details. When I'm editing, I know authors get frustrated that I check all their page numbers etc. I protect your future reader from my current level of frustration!

New xor pattern generalization dropped! For each pixel (x|y) write x and y in base 3, then add the corresponding digits of x and y mod 3. Here we have purple for f(x,y)%4==0 #mathsky

It's Anzac Day in Australia. (Think something like Remembrance Day/Armistice Day, although we mark that as well.) One of my favourite mathematics movies is on TV today - Dam Busters. Come for the music, stay for the maths.

Questions about what does "anywhere on earth" mean. If you submit on the specified day before midnight (like Cinderella) in the time zone where you are, then you are fine. Of course, if you want to imagine you live in the middle of the Pacific Ocean...double check your calculations!

The fifth time is indeed the charm. Writing it all up neatly and nothing has come unstuck! The diagram on half a sheet of paper from several months ago, which I had convinced myself only needed fleshing out a bit when I got around to it was, in fact, not the charm.
