Shout out to "Geometry: A Very Short Introduction" by Maciej Dunajski. Honestly I didn't vibe with the subject but this little book kept me motivated and I liked some of its explanations over the "proper" text books I had (esp for spherical triangles).

My messy affair with geometry has ended. As an attempt at closure (heh!) I wrote a little something about isometries

I'm sure I'll go back to geometry one day, but next up I'm super ready to revisit analysis (with extra variables this time!)

Trying to understand cyclic vector spaces a bit better by writing out a detailed proof of the exercise: if f is a linear map on V, show V is f-cyclic if and only if the minimal and characteristic polynomials of f are equal

Slowly making my way through a second course in linear algebra. Got a bit hung up on a theorem about vector space decomposition, so decided to write something to consolidate the reading around I had to do. Think I got there in the end

Very much enjoyed reading this essay by @wtgowers.bsky.social about the "two cultures" of mathematics: problem solvers and theory builders. I didn't particularly enjoy my reading course on graph theory and combinatorics but it was a good problem-solving workout

My typical set up for studying maths at home #MathSky #Mathematics #Cats

A quick wrap-up of my short reading course on #combinatorics, and some (very) simple number theoretic applications. I was expecting this course to be more painful than it was! #MathSky

Wrapping up my reading course on graph theory with a post about matchings and Hall's theorem. #MathSky

Back at it after Christmas and the summer holidays. Graph theory is a totally new subject for me, so I decided to write down a few thoughts

Wrapping up 2025 and my complex analysis reading course with a little examination of Möbius Transformations ergodicbees.wordpress.com/2024/12/27/m... #mathsky

I did a bit of writing about a complex analysis problem I got stuck on. I have a terrible habit of jumping to conclusions about how to solve things and I wasted a lot of time, but got there in the end :) #MathSky

Optimists: C ∈ [0, ½]
Pessimists: C' ∈ [½, 1]
Mathematicians: C ∩ C'= {½}

Just as I was getting started this afternoon. Perhaps I'll just make this account photos of cats sitting on maths books

My blog is about maths I've been studying and enjoying. Writing about it helps me learn and remember stuff. My last post was about contracting maps and fixed points

... I bet professional mathematicians don't have to work like this

It's traditional to feature a cat for your first post? Apparently maths books are very comfortable
