c/o Leacock 'HUMAN INTEREST PUT INTO MATHEMATICS'

So, for all those years of struggling to understand the question, let alone answer it, you are now telling me: it was all person-centred? Plus! Not only do 'A', 'B', and 'C' have names, there's 'D' too?

    'The student of arithmetic who has successfully striven with money sums and fractions, finds himself confronted by an unbroken expanse of questions known as problems. These are short stories of adventure and industry with the end omitted, and though betraying a strong family resemblance, are not without a certain element of romance. 
    The characters in the plot of a problem are three people called A, B, and C. The form of the question is generally of this sort : "A, B, and C do a certain piece of work. A can do as much work in an hour as in two, or C in four. Find how long they work at it." 
    Or this : "A, B, and C are employed to dig a ditch. A can dig as much in one hour as can dig in two, and can dig twice as fast as C. Find how long, etc., etc." 
    Or after this wise: "A lays a wager that he can walk faster than or C. A can walk half as fast again as B, and C is only an indifferent walker. Find how far, and so forth." . . .

    In the early chapters of the arithmetic, their identity is concealed under the names John, William, and Henry, and they wrangle over the division of marbles. In algebra they are often called X, Y, Z. But these are only their Christian names, and they are really the same people.
    Now, to one who has followed the history of these men through countless pages of problems, watched them in their leisure hours dallying with cord wood, and seen their panting sides heave in the full frenzy of filling a cistern with a leak in it, they become something more than mere symbols. They appear as creatures of flesh and blood, living men with their own passions, ambitions and aspirations like the rest of us.'

'Maggie’s: Architecture That Cares' exhibition

Learning of this exhibition in February, c/o the FT; I wished I'd been able to visit. Now it ends on the 1st November:

'Maggie’s: Architecture That Cares' exhibition at the V&A Dundee.

Hodges' model is a latent 'care architecture' brought to life when applied to person, or community-centred care. Architecture in care, is a theme that keep recurring which is encouraging in its own right.

WHEN
Saturday, October 31, 2026
11:00 AM to 5:00 PM US Central Time

HOW TO JOIN
Online, free, from anywhere:
https://us02web.zoom.us/meeting/register/joyC0lTUQRuX1G3VCb6xcw

In person in San Antonio, Texas ($25 plus service fee, student discount available):

	I was seated in the audience front row, and recognised Heide's symptoms. The crew, behind her, couldn't see that she was about to faint, so I jumped onto the stage and luckily caught her in time. Ever since then, astronauts sit during the debriefs immediately post-spaceflight. Don't need anyone falling and getting hurt. — Chris Hadfield (@Cmdr_Hadfield) October 23, 2026

A little thought experiment - continued:

What's that!

 'A case of individual ineffability.'? 

Is this really ineffable? Are you saying - ironically - this is beyond language? 
That there's something sacred here?
Surely that's a stretch too far? 

I can see it is often complex, maybe difficult to explain too.

Well, the claim of ineffability is justified.
For some people, this touches upon the sacred and spiritual too.

How so? 

Well. Take the global population pyramid we inverted to span the sociological and political domains.
We're all in there. Even if you don't check that dynamic link, that pyramid is 'dynamic'. 
New births are being added, as the newly departed take their leave. 
So it's not just dynamic it's noisy too. 
Strictly speaking it's dancing: a constant shuffle.

Oh, dear! Save me, save us all!
What about the person we pulled out from the masses? 

Yes, one individual, but in truth as our focus, they occupy the interpersonal and sciences domains.
Have you ever used - painted with a palette knife? 

No, I can't say I have, probably not beyond my hands as a child.

Take that person as a single line - the palette knife's edge; then - move the knife, spread those colours across the two upper domains of Hodges' model. Let's say now that instead of a single person as a column, a data point, which we can hardly see; this 'spread' represents their lifespan. Not only that, but in there we also have their unique health career. Plus, arranged chronologically a record of life chances can also be charted.

And that's ineffable? 

True, there's no bright light. But, we can represent here the existential and religious debates and the point that some people get anxious, fearful of death and yet we were not anxious before we started life's inexorable shuffle? 

In these times of AI, it is important to acknowledge that what is ineffable in Hodges' model, is what we human beings can find, can experience in all the domains of  the model and the 'why' that surround it.

Ah, I see. Thanks.

A little thought experiment:

Beneath the humanistic-mechanistic axis (within the sociological and political domains) superimpose an inverted global population pyramid - scaled to fit - of course. Make it dynamic if you wish.

Then imagine lifting just one individual out of the global population. As our subject, of whatever age, sex ... place them anywhere above the horizontal axis. Anywhere within the interpersonal or sciences domains. There they are: a single data unit. Selected at random, of course, their health status would vary accordingly.

Would we actually be able to see them here? One single vertical line, at this scale? 

A case of individual ineffability. Welcome to the ethical debate re. the individual and collective. And yet there they are? The focus of their own self-care and independence, famine, conflict ... or our care. Not just 'us', as a nurse, doctor, social worker, support worker ... but intermittently, the whole health and social care team.

From being lost in anonymity, literally a number in a chart, to having a name, several identities - with or without 'papers' - needs, background, character, personality, problems, relationships, strengths and humanity.

Hodges' model provides an incredible conceptual estate for us to utilise, if we choose to.

We can refer back instantly as context and population pyramids demand to parent, guardian, partner, family.

or, at least your planned monitoring rationale,

measures - metrics river health 'There is a chance that results will get better over time. Leon Barron, professor of environmental science at Imperial College London, said water quality metrics could lag behind and needed to be taken over multiple seasons and years to get an accurate reading.' 1,3,5,10 ... years? What is local? What is national?

public health  'Amy Fairman, head of campaigns at environmental charity River Action, called the independent pollution figures "deeply shocking" and demanded that Tideway publish its internal data in full. "The public deserves to know, given they are paying for this tunnel through their water bills, that it is actually delivering improvements," Fairman said.'

'Tideway argued that assessing water quality trends required multiyear data-sets and that a single year of observation "would not provide a sufficiently robust picture". "The Thames is a complex tidal river, and water quality is influenced by a range of factors beyond the combined sewer overflows that Tideway was designed to address," it added. "Individual E. coli readings can fluctuate depending on location, rainfall, tides and other inputs. These readings cannot, in isolation, provide a complete picture of the tunnel's impact."

Windermere will be a different story then?

Aberfan - 60 years

As for many children (one hopes) my future education, motivation and aspirations were framed by my parents. Pivotal was my father, and having the opportunity. Growing up in mid-Wales he had been surrounded by mines and quarries. My grandfather had worked in a slate mine, walking there and back to the village and home. 

There was a real fear that I'd end up down working down the mine. Value judgements, courage and community aside, my father witnessed some of the realities of pit/quarry life. So for me, and a brother and sister who followed, it was school, school, school (perhaps you can tell?).

There were many reminders: records of Welsh choirs; films such as How Green Was My Valley. In my early teens this theme was there in English classes, as we read and discussed D.H. Lawrence's, Sons and Lovers. Living near Wigan, we in turn were surrounded by mines, many already closed. Golborne colliery was an exception. There was an accident there in 1979 after we had left school. 

Perhaps also it was a sign of a future career pathway, as I noticed the impact of the Aberfan disaster now 60 sixty years ago on my father. I was a similar age to the children who lost their lives. In the news this week it is remarkable, salutary and shaming the similarity with more recent major incidents with loss of life, here in the UK. The lack of regard for accountability, and social justice.
