People have expressed interest in deep topics, so this list focuses on philosophical questions.

How would society change if men were able to get pregnant and men and women both had an equal chance of getting pregnant?


Abortion and birth control would be free and legal everywhere. Family leave would be generous. Childcare would be free. It would be a lot better all around.

That's a pretty good show, although she ruined it by guessing all the plot twists.

"Is AI more important than climate?"

When the BBC recently asked Google and Alphabet CEO Sundar Pichai whether the build-out of AI is more important than climate, the question briefly cut through the hype that usually surrounds the AI boom. Pichai acknowledged that AI is dramatically increasing energy in ways current systems “can’t fully cope.”


Another way in which humanity is too stupid to stop sawing off the branch we're all standing on.

AI is not more important than the climate, it is just the latest threat to the climate. AI is a massive energy hog that we cannot afford at a time when we need to be cutting emissions as fast as possible. The most effective way to do that is to use less energy. AI is the opposite of helpful in this regard.

Today is cloudy and cold.  The snow is melting in patches.

I fed the birds.  I've seen a large flock of sparrows, a pair of cardinals, and a starling.

I put out water for the birds.

EDIT 2/6/26 -- I did a bit of work around the patio. 

EDIT 2/6/26 -- I did more work around the patio. 

I am done for the night.

For the first time in 87 days we got above freezing today! Just for a couple hours in midday but still, it was there. ... Also we got another inch or so of snow, just in time to make [personal profile] bunnyhugger's fourth drive up to work this week lousy. But it also meant we have a somewhat clean-ish driveway for the first time in a month or so, with the snow and ice scraped clean. That's nice.

It also puts me in mind of unending days in the 90s or above, like during the Most Extreme Mid-Atlantic Parks trip, and our day at Kennywood that was too short because for some reason they closed at like 8 pm against all reason and decency:

P1100310.jpeg

Here's the Lucky Stand, now a self-service pop refill station, and the silhouette of The Phantom's Revenge in the late afternoon light.


P1100317.jpeg

And the fountains of Lost Kennywood's midway looking into the late sun.


P1100323.jpeg

We're back to the Grand Carousel for the last ride of the day!


P1100327.jpeg

And here's a picture of a horse with the pole almost lined up to the decoration of the railing around it. This is a good idea that maybe I can execute better next time.


P1100342.jpeg

So, shockingly, Kennywood closed before sunset that day. The result is the traditional picture from the bridge looking out at Racer and Jack Rabbit over the lagoon looks like this instead.


P1100345.jpeg

There's the carousel with the lights all off suddenly. They closed it fast on us, including running a weirdly short cycle after waiting for everybody to get on.


P1100348.jpeg

This directional sign is new but I like it, for building on the Kennywood Arrow and for letting all the attractions have their own typefaces.


P1100352.jpeg

We didn't even get to see if the Refreshments neon was still neon!


P1100354.jpeg

Since the park didn't have printed-out maps I grabbed a photo of one of their too-few map signs.


P1100364.jpeg

Spotted this car in the parking lot. Wonder if it's an amusement park fan's.


P1100368.jpeg

This is a picture outside our motel room. [personal profile] bunnyhugger found a spot with a great 50s-60s style layout (the interior was sadly fresh-renovated) that was really sweet.

Here's the road sign which could not be much better.

Classroom

When you take a linear algebra course and get to the chapter on eigenvalues, your homework problems will include a small matrix A and you will be asked to find the eigenvalues. You do this by computing the determinant

det(A − λI) = P(λ)

and getting P(λ), a polynomial in λ. The roots of P are the eigenvalues of A.

Either A will be a 2 × 2 matrix, in which case you can find the roots using the quadratic formula, or the matrix will have been carefully selected so that P(λ) will be easy to factor. Otherwise, finding the roots of a polynomial is hard.

Real world

Numerical algorithms to find eigenvalues have gotten really good. In practice, you don’t compute determinants or find roots of polynomials. Instead you do something like the QR algorithm.

Finding all the roots of a polynomial is a challenging problem, and so what you might do in practice is find the roots by constructing a matrix, called the companion matrix, whose eigenvalues correspond to the roots you’re after.

Summary

As a classroom exercise, you calculate roots of polynomials to find eigenvalues.

In the real world, you might use an eigenvalue solver to find the roots of polynomials.

I wrote a similar post a few years ago. It explains that textbooks definite hyperbolic functions using ex, but you might want to compute ex using hyperbolic functions.

The post Eigenvalue homework problems are backward first appeared on John D. Cook.

Ten years ago, when the Spartan HPC system was launched at the University, it was small, innovative, and experimental, its very name a laconic reference to the funding provided (i.e., not much). But the tricky combination of traditional HPC flexibly supplemented by cloud VMs for single-node jobs worked, and over the years, it would become one of the world's most powerful supercomputers, supporting thousands of researchers with the computational power required in engineering, astronomy, mathematics, economics, climate science, and especially the various medical and life sciences. One of the decisions we made at the time was that Spartan would be open and collaborative; researchers could come from anywhere in the world, as long as the project's principal investigator was from the University of Melbourne. It was an openness that has allowed hundreds of researchers to access the supercomputer resources.

There has been, however, a change in policy and not one to my liking. Now each project requires a university supervisor, and each external collaborator requires a University email address, with the supervisor making a separate application for each individual. This is an overly bureaucratic procedure, in my opinion, and if there's anything IT workers hate doing, it's wrangling systems to meet unnecessary bureaucratic requirements. It's wasted work and time that provides no change in outcome; mathematicians would describe it as "inelegant", engineers would call it "suboptimal", economists would call it "damaged goods", you get the idea. My unfortunate role this week has been to get a list of active non-University researcher accounts and craft individual emails to each of them and their university supervisor, informing them of their need to apply for new email addresses. Due to nuances that I won't go into (such as one user many projects) it was not a matter of just making a single SQL database extraction, but rather required several steps of data wrangling.

The procedure was a bit of an annoyance, an interesting technical challenge, but the real moment of joy was achieved by going through the various projects: ecosystem population connections in tropical oceans, molecular modelling of novel antivirals against SARS-CoV-2 proteins, cosmic birefringence from the South Pole telescope, subterranean dark matter studies - and so it goes on. It is the range, diversity, and importance of these projects that inspire me, a quest for objective knowledge without partisanship, in a world where universal norms are betrayed by the influences of power and wealth, and aesthetic expressions are either trite or manipulative rather than sincere expressions of the imagination. As I tell researchers in my introductory class, you are the people who will make the discoveries and inventions that hopefully will make the world a better place. I'm just going to show you how to harness the resources of a supercomputer to make this easier for you. So even when I'm deeply engaged in a project I find grossly and even offensively unnecessary, there are still some parts that bring joy and hope.

Do I need to ask, guess the critic, given the headline on this review of the Gwen John exhibition: In a superb, mystical retrospective, the painter sheds social trappings – and her clothes – as she uses her enormous intelligence to paint purely. JJ, go and take a cold shower!

I am not sure that exorcism is quite what is needed in the case, unless he starts doing manifestations in galleries of writhing and speaking in occult tongues and so on: Demand for exorcisms rises as faithful want ‘deliverance from evil’. And in fact it all sounds rather low-key:

Even when an Anglican priest does perform an exorcism, they are nothing like Hollywood horror scenes with “shouting and screaming” and demonic drama.
They are “quiet and calm” affairs where a priest prays with a troubled person, usually after consultation with a psychiatrist and safeguarding experts.

One does feel that this is in the tradition of the C of E! Maybe with a nice cup of tea afterwards....

Knepp: Wilding from the Weald to the waves:

After inheriting the estate from his grandparents in 1983, Charles Burrell soon realised that large-scale farming was impossible on low-lying clay land. So, in 2002 he and his wife, author, and journalist Isabella Tree, embarked on what has become a pioneering rewilding project converting pasture into a patchwork of grasslands, scrub, groves, and towering oaks. Now home to storks, beavers, and nightingales, to name a few, Knepp’s ever-evolving experiment is open for all to enjoy.

Call me a cynical old bat, but I can't help feeling that this is in a Grand Old Longstanding Tradition of landowners doing whatever is The Latest Thing with the estate they inherited. And these days it is not either, tart it up like unto the gardens he saw on his Grand Tour in Italy, introducing various invasive species animal and vegetable, or, set up a funfair and safari park as a remunerative enterprise to enable him to pay off the crippling death duties the iron heel of Clem Attlee and Co has imposed, but to get acclaim for this absolutely on-trend thing to do with his land.

This is a different kind of heritage: Heritage Unlocked: Birmingham’s Unique Municipal Bank:

Birmingham Municipal Bank (1919-1976) was unique as the first and only local authority savings bank in England. Unlike other savings banks (such as the Trustee Savings Banks), customers could borrow money through the House Purchase Department to buy their home. Unlocking the Vaults, has been uncovering the Bank’s history and how it helped shape Birmingham’s story. The Exchange (opposite the Library of Birmingham) was once the head office for the Municipal Bank, and it lies at the heart of this project with many projects and events taking place in the historic Vaults.
Historic black and white photo of the Birmingham Municipal Bank, showcasing its grand architecture with tall columns and detailed facade.
....
A key finding of the project has been the significance of the Municipal Bank, not only as a financial institution but also as a cornerstone of community life, with local branches established on high streets across the city between the 1920s and 1970s.

The rise of ‘low contact’ family relationships - in fact, point is made in there that perhaps what there has been is a rise of is families being all up in one another's business because of Modern Technology and tracking devices, family group chats, the ability to know where family members are and what they are up to at all hours of the night and day.

Because I would not at all describe my own family as 'low contact', we just did not live in one another's pockets and need to be constantly informed and have opinions about each other's lives. Weekly phone-calls - occasional visits- etc etc.

I'm not surprised people feel smothered and overwhelmed when I read some of the shenanigans that families do but then, am introvert to start with.
