3) Visit to the library before I pick up my bike,
BONUS: Lunch on a sunny terrace of a bar nearby
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
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:
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.
And the fountains of Lost Kennywood's midway looking into the late sun.
We're back to the Grand Carousel for the last ride of the day!
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.
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.
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.
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.
We didn't even get to see if the Refreshments neon was still neon!
Since the park didn't have printed-out maps I grabbed a photo of one of their too-few map signs.
Spotted this car in the parking lot. Wonder if it's an amusement park fan's.
This is a picture outside our motel room.
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.

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.
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.
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.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.

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.

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.

....
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.
