The other day I was thinking about how to better capture thoughts that come up when you are doing a collaborative modelling session.

So I be been trying a new format:

🕳️ Gaps: Is there anything not covered by this representation of the system that you think should be there , or it’s not represented well

🌱 Growth: Are there some areas here that could give us an edge, alternatively some improvements.

✨ Great: Reasons you love this system representation or the system itself.

🚌 Grind: (think of the daily grind) aspects of the system / this diagram that feel unnecessarily complicated or hard to use or understand

List all the numbers:

1, 2, 3, 4, 5, 6, 7, ...

skip every second one:

1, 3, 5, 7, ...

form the partial sums like this:

1, 1+3, 1+3+5, 1+3+5+7, ...

Hey, you get the square numbers!

1, 4, 9, 16, ...

Lots of people know that. But now list all the numbers

1, 2, 3, 4, 5, 6, 7, ...

skip every *third* one:

1, 2, 4, 5, 7, 8, 10, 11, ...

then form the partial sums:

1, 1+2, 1+2+4, 1+2+4+5, 1+2+4+5+7 ...

=

1, 3, 7, 12, 19, ...

then skip every *second* one:

1, 7, 19, ....

then form the partial sums again:

1, 8, 27, ...

Hey, now you get the cubes! You shouldn't trust me based on so little evidence, so do some more, or prove it works.

But the cool part is that this pattern goes on forever. If you list all the natural numbers starting from 1, skip every nth one, form the list of partial sums, skip every (n-1)st one, form the list of partial sums, skip every (n-2)nd one, ... blah di blah di blah... skip every 2nd one, then form the list of partial sums, you get the nth powers!

This is called Moessner's theorem, and I learned about it from Michael Fourman. It's in Chapter 7.5 here:

• Jan Rutten, The Method of Coalgebra: Exercises in Coinduction, ir.cwi.nl/pub/28550/rutten.pdf

Moral: anytime you see a pattern in mathematics - one that goes on infinitely, not a coincidence! - it's probably just the tip of a bigger iceberg.

"The Luddites wanted technology to be deployed in ways that made work more humane and gave workers more autonomy. The bosses, on the other hand, wanted to drive down costs and increase productivity. As historian David Noble puts it, “The Luddites were perhaps the last people in the West to perceive technology in the present tense and to act upon that perception.”"

"Most important, though, is you. Will tidying bring peace, satisfaction, and joy to your programming? Maybe some. This is important because if you are your best self, you are a better programmer. You can't be your best self if you're always rushing, if you're always changing code that's painful to change." - Tidy First? by Kent Beck

Closed shops as a sign of a healthy city. I like seeing the home-made ’we’re on holidays, back in a month’ signs on small businesses at this time of year. I take it as a sign that the city centre is truly mixed-use with room for one-person and family businesses. And with room for a local community of ordinary residents who just think ’ah, well I hope Inger has a nice holiday, my dry-cleaning can easily wait.’

It was anarchy out there. The neighbours had organised a block party and the house at number five was giving away lemonade.

Every once in awhile, I think of my favorite “…the fuck did you just say?” phraseology, which is from Homer’s Iliad, proving we have never, ever changed as a species, only become less fancily inclined.

This is your regular reminder that if you are the smartest person in the room, go find another room. You are not going to run out of people or rooms.
