Fulltime freelance provider of outreach and enhancement in maths ... I talk a lot. About maths.

I talk about other stuff too, like ballroom dancing, juggling, unicycling, education, engineering, software, and "other things".

But mostly about maths.

I tend to follow back, but only if you have something in your profile.

People who moved to the UK from somewhere else: is Argos weird, or is it charming?

ColinTheMathmo,
@ColinTheMathmo@mathstodon.xyz avatar

@christianp To me it was ... unexpected. But then it was logical, though still a bit unusual.

It's certainly not charming, but never tipped over into weird.

It looks like I mis-timed things and I'm going to be promoted to the next league in Duolingo.

For today’s Worldle, Sydney is the alleged capital of Australia. Hoo boy.

@danpmoore What?

That's ... bizarre.

Do you have a link? I don't play worldle ...

ColinTheMathmo,
@ColinTheMathmo@mathstodon.xyz avatar

@danpmoore OK, I went hunting, found it, found how to get it to ask me for the capital, entered "Sydney", and it marked me as wrong.

So ... colour me confused.

@KarenCampe Nice one!

'Jail' and 'Prison' are synonyms. But 'Jailer' and 'Prisoner' are antonyms.

@iris This is an interesting distinction of which I was unaware. It actually seems to be a dialectic difference ... not everyone I know makes this distinction.

But yes, they're different (sort of) and yes ... you are being pedantic!

The irrationals are those exactly those reals that are a different distance from every rational.

ColinTheMathmo,
@ColinTheMathmo@mathstodon.xyz avatar

@soaproot I find it a confusing characterisation ... it's ready to get lost as to exactly what implications are needed to be proved.

It's tricky, and I find it unexpected once I start to get into it.

ColinTheMathmo,
@ColinTheMathmo@mathstodon.xyz avatar

@soaproot I think I'd need to have a Very Hard Think to follow that ... and I don't have time just now.

I am, however, interested to see where you go with it.
