A simulation of a wave inside a stadium- a rectangle and two semicircles. Although it is a very simple shape, the wave function cannot be exactly solved and becomes chaotic. The simulation is actually computed on a rectangular grid of pixels as a cellular automaton- note the checkerboard patterns and pixelated edges.

How the Scandinavian country became a literary powerhouse.

The Dial:

On the train heading inland along Norway’s largest lake, Mjøsa, I felt ill at ease with my task. I was on my way to Lillehammer, a small town whose claim to fame is that it hosted the 1994 Winter Olympics, to attend the Norwegian Festival of Literature, which bills itself as “the largest of its kind in the Nordic countries.” 

Norway, a country of 5.5 million people, has in the last decade exported more buzzy books than any of its larger neighbors. I was here to report on the great mystery of why that was. Why does Norwegian literature do disproportionately well abroad? Is it just a matter of state funding? Or could it have something to do with Norwegian habits of self-portraiture and the way that books made in Norway tend to correspond to expectations and demands elsewhere? Or might it be that our most exportable heavyweight writers, Nobel laureate Jon Fosse among them, were a generation bred in a now bygone ecosystem of in-house magazines, literary journals and academic hubs? The festival seemed like a good place to try to answer these questions.

“In this case, the federal government prohibited us from sharing any information,”

Raphael Satter:

Unidentified governments are surveilling smartphone users via their apps’ push notifications, a U.S. senator warned on Wednesday.

In a letter to the Department of Justice, Senator Ron Wyden said foreign officials were demanding the data from Alphabet’s (GOOGL.O) Google and Apple (AAPL.O). Although details were sparse, the letter lays out yet another path by which governments can track smartphones.

Apps of all kinds rely on push notifications to alert smartphone users to incoming messages, breaking news, and other updates. These are the audible “dings” or visual indicators users get when they receive an email or their sports team wins a game. What users often do not realize is that almost all such notifications travel over Google and Apple’s servers.

That gives the two companies unique insight into the traffic flowing from those apps to their users, and in turn puts them “in a unique position to facilitate government surveillance of how users are using particular apps,” Wyden said. He asked the Department of Justice to “repeal or modify any policies” that hindered public discussions of push notification spying.

In a statement, Apple said that Wyden’s letter gave them the opening they needed to share more details with the public about how governments monitored push notifications.

Civics: “Weimar America”

Victor Davis Hanson:

At Hillcrest High School in Queens, New York, hundreds of students rioted on news that a single teacher in her private social media account had expressed support for Israel. Waving Palestinian flags, and screaming violent threats, the student mob rioted, destroyed school property, sought the teacher out and tried to crash into her classroom—before she was saved from violence by other teachers and an eventual police arrival.

The subtext was that the overwhelmingly minority students (whose school is ranked academically near the bottom among New York City schools) were acculturated to the racist reality that as the “oppressed” they were exempt from any punishment for hunting down their own teacher. As a Jewish (and thus white) “oppressive” supporter of Israel, she was reduced to, in the words an enthusiastic commenter on a Tik Tok video of the riot, a “cracker ass bitch.” And so the student pack tracked her down as if they were hunting an animal. The old Nazi youth gangs tried to kill Jews because they were not considered “white;” our new Nazis hunt them down because they allege that they are. The common denominator between the 1930s and 2023 is an unhinged hatred of Jews.

Hundreds of such incidents are now occurring on a daily basis—as the country is leaving its Weimar phase and heading at warp speed into normalizing Jew-hatred and worse. Instructors singled out Jewish students in classes at UC Davis and Stanford. Pro-Hamas students ripped down posters, swarmed public buildings, and disrupted traffic.

Now, according to one college counselor, a $2 million check might be the new $20 million.

Rikki Schlott:

“If a billionaire has committed $50 million or $100 million a year and now they’re backing out, colleges need to figure out how to fill that gap,” Command Education founder Christopher Rim told The Post.

“The only way to do that is by recruiting lower amount donors.”

Since Hamas’ October 7 attack on Israel, many elite colleges have been accused of failing to tackle antisemitic demonstrations on campus and refusing to straightforwardly condemn the mass murder.

K-12 tax & Spending Growth: California $pending

Katy Grimes:

When Gov. Jerry Brown was elected in 2011, the state budget was $98 billion. The state’s population was a little over 38 million. Brown doubled the budget to $199.3 billion – with no measurable increase in population. Gov. Newsom inherited Brown’s $199.3 billion budget, and has grown it to $330 billion in 5 years – while losing population. Where is all of that new spending going?

The well endowed university Presidents

Tyler Cowen

Here is three and a half minutes of their testimony before Congress.  Worth a watch, if you haven’t already.  I have viewed some other segments as well, none of them impressive.  I can’t bring myself to sit through the whole thing.

I don’t doubt that I would find their actual views on world affairs highly objectionable, but that is not why I am here today.  Here are a few other points:

1. Their entire testimony is ruled by their lawyers, by their fear that their universities might be sued, and their need to placate internal interest groups.  That is a major problem, in addition to their unwillingness to condemn various forms of rhetoric for violating their codes of conduct.  As Katherine Boyle stated: “This is Rule by HR Department and it gets dark very fast.”

How do you think that affects the quality of their otherdecisions?  The perceptions and incentives of their subordinates?

2. They are all in a defensive crouch. None of them are good on TV. None of them are good in front of Congress. They have ended up disgracing their universities, in front of massive audiences (the largest they ever will have?), simply for the end goal of maintaining a kind of (illusory?) maximum defensibility for their positions within their universities. At that they are too skilled.
