Howdy! I'm currently a PhD student #mathbio but have an eclectic mix of interests/specialties including:

🧶knitting/crochet/cross-stitch
🦻accessibility esp. in maths
👨‍🏫maths education
🧮operations research
🎵classical music

And am always groaning about how little time there is to learn everything!

Minor Cooking Win: Sweet red bean paste recipe I was following recommended 1.5 cup sugar to 1 cup dried adzuki bean ratio. I thought the amount of sugar seemed a bit excessive, so I tried a 1:1 ratio instead and the sweetness came out the way I wanted it. Whew!

Made chicken masala for meal prep. Decided to try making tadka first: heat up ghee until smoking, then fry spices in ghee, then add the rest to prefs.

The resultant smell is VERY reminiscent of whenever I'd walk into a South Asian household 😅 "Ahh, that's IT!" /chefkiss

I learnt about a few more via this QI clip 😂 www.youtube.com/watch?v=ICaP...

I suspect this would be easy to computationally check, though. Just need a reference dictionary.

Yep, the school is mentioned in the article so I'll probably do that. Leave my details, say I'm available for a chitchat when exams are over.

I got news of a blind Year 12 student doing maths interstate and was thinking of reaching out. Apparently reaching out in that way isn't acceptable on some social norms/ethical level according to initial conversations 🤔

Just very worried about his eventual uni experience and wanting to offer advice

I keep stumbling into and discovering things normal to me that is completely alien to the majority and some days it's like "Oh god please make it stop can I just have like one NORMAL thing in common with the majority?!"

🧠: No! You must be quirky in this congratulations card!

It's been interesting as a mathematician having conversations with my housemate doing a PhD in machine learning where he's talking about concepts at a higher level & combining algorithms and my brain's like "Grr I want to scrutinise each and every part of what you're doing 😅"

I'm open to teaching approaches being adjusted but my main point is that we shouldn't eschew getting students to write and debug code by hand (and other traditional teaching means) because it's still a useful skill to have and develops their mental capacity.

Matt Mack @matthras.bsky.social · 2d

One giant asterisk I need to point out is that you, with your years of experience, expertise and ability to describe and evaluate, are able to do all that.

The students that we teach have none of that, and they have grown up in a mobile/tablet dominated world.

Today:

👎A few too many small oops caused by my brain. Silly brain. /shakesfist

👍chkdsk on my PC has finally finished running after like 4-5 days of not being able to use my PC. I stupidly set it to run after boot instead of unmounting & scanning separately.

I've been thinking a lot about means recently!

Probably some combination of (1) teaching our data analysis unit in our STEM 101 course at Oglethorpe and (2) all of @howiehua.bsky.social's great posts surrounding Mean Girls Day.

I'd like to show how some of these various means are related.

Top left (red background): Arithmetic Mean, labeled “AM = (x₁ + ⋯ + xₙ) / n.”

Top right (dark blue): Geometric Mean, labeled “GM = ⁿ√(x₁ ⋅ … ⋅ xₙ).”

Bottom left (purple): Harmonic Mean, labeled “HM = n / (1/x₁ + ⋯ + 1/xₙ).”

Bottom right (dark green): Quadratic Mean, labeled “QM = √((x₁² + ⋯ + xₙ²) / n).”

Excellent resource!

I am looking forward to <math> inclusion as well.
