I think we might run into discrete Vs continuous. My mum natters all day? Hmm although that's the verb. I like natter.

Although my thought began because I was thinking about the word modicum.

It's like how we talk about loads of things being as thin as a human hair, but never as thick as 7 hairs

I will have a modicum of respect for anyone who can give me a word that is exclusively used in the singular

You can also do it with a map to work out the earth's surface. But it turns out the earth is actually significantly larger than most maps.

In today's episode of "I reckon I could probably do that", I just changed the starter motor of my car. It works again!

Next week on "I reckon I could probably do that", will I be able to fix the radiator in the bathroom?

So who first introduced the river crossing problem? Or the Jeep Problem?

Why our good friend Alcuin of York. Have a listen to the final episode of #TheMathematiciansPodcast to find out more.

I just recorded my final 50th episode of #TheMathematiciansPodcast for this series. It's been a blast. The show will continue, but now much slower; and we will return in the new year with the story in India.

You can hear the final ep tomorrow.

Or support the next series with the link in my bio.

Could be, but they are just led lights, so I would have hoped it would be fairly stable

I just saw a product advertised as 12 kilo watt hours per 1000 hours.

So... 12W ?

Today I learnt:

If you inscribe and circumscribe a million-gon around a unit circle. The two areas would approximate pi to only 10 dp.

(In truth, the approximation is valid by equal truncated values, and actually needs a regular polygon with 1,006,284 sides)

Released today, the penultimate episode of #TheMathematiciansPodcast of the Hellenistic series, with a surprising monk from Northumbria, born 755AD
#Bede the venerable, very arguably a Mathematician, find out why. The guy that gave us calendars and counting

TIL why you cannot construct a regular heptagon with compass and straight edge. I'll tell you all about it on the next episode of #Un-NaturalNumbers which we record tomorrow. Very excited!

A Reddit screenshot: This sounds like a job for a fermi approximation. I buy a week's food for 2 people when I shop. I think I visit less than 1 in 1000 items. In that for every 1000 distinct products they sell, I think I have 1 of them. I think whenever I buy an item there are about 10 on the shelf, and probably another 10 behind the scenes. So 2x1000x10x2 = 40,000 weeks for 1 person. The average human lasts 4000 weeks. So 1 shop can support 10 people their whole lives. Edit. Formatting

A person on #Reddit asked if one person could survive an apocalypse with only the contents of a supermarket for the rest of their lives (ignoring expiry dates)

What was the last #FermiApproximation you did ?

If you format your LaTex equations using £\text{pounds}£ instead of $\text{dollars}$, then they are 32% more correct in the current exchange market.

I've been watching old episodes of Mr Bean with my daughter. The physical comedy is timeless, but it's really hard to explain the context of what life was like in the 90s.

I am wondering if I have a problem with #oeis searching... It's becoming obsessive

My second sequence just dropped!

Numbers k with the property that k is the next number that cannot be expressed as a linear sum of the squares of any of the preceding terms

Very happy with that.

1, 2, 6, 7, 11, 15, 21, 25, 61, 106, 142, 155, 515, 551, 36208...

Don't forget to support this great maths book, if you want more fiction adventures that incorporate abstract maths... #MathFi ?

Very happy to share today's episode of #TheMathematiciansPodcast

Want to know what is so special about the #HagaSophia, then listen in as we discuss the mathematicians who designed it. Alongside this, a tale of a nearly lost work by #Archimedes

I am absolutely buzzing following the publication of my very first OEIS sequence.

oeis.org/A389751

Numbers k such that k^3 can be represented as the sum of k consecutive nonprimes.

Eg

a(3) = 9^3 = 76+77+78+80+81+82+84+85+86

Only the first 16 numbers found so far, so please come and add more!

I just had a letter box delivered... Which uses up my irony budget for the week.

Just this year's quince harvest.

Talking to my 3-year-old another day:

"We played the floor is lava today"

(Ooh a teaching moment)

"Oh right, and what is lava?"

...

"The floor"

Well played Lily, you out smarted me.

I had another delightful maths moment with @hopeiona.bsky.social, where we talked at length on the nature of #infinity. If you'd like to listen in then you can find our interview here.

From ancient history to ZFCs.

Fun fact: a "UK-five" is actually a CRV normally distributed between 3 and 7

It turns out it's really hard to draw #Isometric paper by hand.

My teacher always told me I wouldn't walk around with a protractor in my pocket, and it turns out she was right.

In other news, I might have discovered a new #OEIS

Spoiler: 1, 6, 18, 45, 87

I do love it when I am browsing the #OEIS and I find a comment that was within the last few weeks. Oddly titillating to know that someone else passed this way so recently.
