As always, comments and criticisms welcome.

@ColinTheMathmo Oh, 'twas my pleasure. Quite literally, as your diagram provided me with an incentive to figure out how to use cairo from Haskell.

As Easter is coming up, I'd like to take a moment to say that bunnies are cute but also huge dickheads. They're rarely docile and cuddly and will absolutely destroy everything you love.

They live 10+ years, cost as much as a dog, and need a lot of time and attention. 75% of rabbits in the UK are neglected and many bought at Easter don't even make it to a year old.

Know what you're getting into, or stick with chocolate.

@rnather Not at the moment - thanks. There have been some issues spotted with my explanations, so I may be a few days getting it sorted. If there is anything I'll let you know.

And thanks again.

Q: What do you get when you cross a mosquito with a mountaineer? A: Nothing - you can't cross a vector with a scalar.

@rnather That's one of the things I was looking for, thanks. If I can find a clean narrative I'd like to use that, so how would you like to be credited? Name? Handle? Link? See here for examples:

So I'm moving up to Edinburgh in the next three months. Do I know anyone connected on Masto who lives up there? :)

Would love any advice you have!

A request for those into both maths and technology - I need a diagram with an ellipse & a circle, each of the same area, the circle centred on one of the foci, & the ellipse a little eccentric, but enough to be clearly different from the circle.


I can draw an ellipse, & I can probably work out where the foci are, but getting them honestly of equal area is trickier. Ideally a diagram showing a family of ellipses of equal area, sharing a focus, including the circle, would *also* be good.

I was obliged to be industrious; whoever is equally industrious will succeed equally well. -- J.S.Bach

My latest bloggy thing:

As always, comments, thoughts, criticisms, and feedback, all welcome.

Have to say that this "one blog post per week" is a brutal schedule.

@wendyg That's fine - if you post work links, people who share your interests will (I hope!) start to find you and follow you.

Looking forward to seeing what you share.
