Idly had the thought “I wonder if Donald Knuth is still doing a Christmas lecture?” And the answer is of course he is, it was yesterday. Eighty-seven years old, still on the wholly Quixotic TAoCP path, and casually spitting out TeX fascicles. www-cs-faculty.stanford.edu/~knuth/fasc8...
It's convenient to redraw Fig. 121(b) as three concentric rings, without crossing edges, as shown in Fig. 122(a). Then it's easy to find a Hamiltonian cycle, such as the one indicated by bold edges in Fig. 122(b). (In fact, Hamilton proved that every such cycle on the dodecahedron is essentially the same as this one; see exercise 9.) Thus we can also redraw the dodecahedron's graph as shown in Fig. 122(c). From that diagram it's obviously Hamiltonian - that is, it obviously has a spanning cycle; but it's not obviously planar at first glance. was acquired in 1911. A similar example, smaller and with more beautiful let-terforms, is object number UC 59254 in the nearby Petrie Museum of University College London [see W. M. F. Petrie, Objects of Daily Use (1927), #288]. What a pleasant coincidence that W. R. Hamilton himself would independently come up with the same concept some 1800 years later, and would proceed to find a closed cycle instead of just a path! Now fast forward to the ninth century, are equivalent to the tours of bunches aza3a4a1, a3a4a1a2, and a4a1a2a3 whenever each aj is one of the 28 wedge codes. Reflection also gives an equivalent tour, whose bunch depends only on the unreflected bunch name. For example, the top-bottom reflection of cycle (1) gives a cycle that belongs to bunch yByD. In general, let p and r be the permutations of wedge codes that correspond to 90° rotation and to top-bottom reflection. Then a → ap is the mapping discussed in Fig. 123, and we have a=abodefghijklABCDEFGHIJKLwxyz;

The agonizing long tail of disaster recovery is underexplored. I think a lot about this 2024 study finding that when a hurricane hits somewhere in the U.S., the people there are more likely to die *for the next 15 years*. www.nature.com/articles/s41...

Circular diagram showing four connected stages with arrows: 1) The world adopts policies to discourage air pollution, 2) U.S. conservatives reject the policies and block U.S. environmental policies, 3) World doesn't change policies; European & Asian firms develop technology to comply with new global low pollution standard, 4) U.S. becomes less industrialized and continues to fall further behind technological frontier, which loops back to stage 1.

If we're not at war, Pete Hegseth is a murderer. If we are at war, Pete Hegseth is still a murderer. He's a murderer. And you don't need to go to The Hague to hold him accountable because there are perfectly good, American laws AGAINST MURDER.

Pete Hegseth Should Be Charged With Murder
No matter how you look at the strikes on alleged “drug boats”—as acts of war or attacks on civilians—Hegseth has committed a crime and should be prosecuted.

After World War II, 3 German U-boat crewmen were sentenced to death for machine-gunning Allied sailors who were clinging to life rafts after their boat was sunk.
It's long been known in the military that this is a war crime. Pete Hegseth must be fired and prosecuted.

1. Jared Kushner's trip to Moscow yesterday was not just unethical; it was illegal.

You cannot accept tens of millions of dollars from foreign governments and simultaneously conduct high-level diplomacy for the federal government.

It says it right in the Constitution.
Kushner’s Moscow mission wasn’t just corrupt. It was unconstitutional.
Jared Kushner, President Trump’s son-in-law, has been traveling the world to participate in high-stakes foreign policy negotiations on behalf of the president.

After becoming a congressional leader, a politician’s stock portfolio beats out those of peers by 47 (!!!) percentage points a year through trades timed around bills and firms that later get government contracts

www.nber.org/papers/w34524

via @florianederer.bsky.social
"Captain Gains" on Capitol Hill Shang-Jin Wei & Yifan Zhou WORKING PAPER 34524 DOI 10.3386/w34524 ISSUE DATE November 2025 Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms. 令 1 1 -9 -8 -7 -6 -5 -4 -3 -2 -1 1 2 3 4 5 7 8 9 Year Figure 2: Estimated dynamic quasi-difference-in-differences coefficient, di, of equation(3), with vertical dashed lines representing 90 percent confidence intervals. The point estimate of the year in which the lawmaker became a congressional leader (Year 0) is normalized to zero. BHAR over the 250 days following each trade is the dependent variable and calculated using the Fama-French five-factor plus momentum as the benchmark model.

Who needs Sec of State or any US official actually confirmed by the United States Senate to do official state business on behalf of the United States?

Just let the President's cronies and family members with potential financial interests tied to foreign entities do it.

Department of Defense Law of War Manual, Sec. 18.3.2.1 states the "requirement" to refuse illegal orders.

What’s its key example? Wait for it . . . It’s "orders to fire upon the shipwrecked."

Klein Bottle With the Image of its Own Making 🧮
Large glass Klein bottle with video of its creation projected onto the bottom Large glass Klein bottle with video of its creation projected onto the bottom Gary Hill American, born 1951 Klein Bottle with the Image of Its Own Making (after Robert Morris), 2014 Blown glass, micro video projector, media player and one USB drive with media file, cables, MDF, latex paint Museum Purchase: Funds provided by the Contemporary Art Council and an Anonymous Donor, 2014.75.1a,b A Klein bottle is a non-orientable surface, meaning it has only one side; it is continuous, like a Möbius strip. Glass blowers can model something similar, but to create the theoretical form, you need the fourth dimension of time and space. Gary Hill does that here by picturing the making of the bottle within the form itself. In an art historical pun, Hill references Robert Morris's 1961 Box With the Sound of Its Own Making.

DHS using its massive new budget keeping Americans safe from [checks notes...] a law-abiding college student who grew up in America & whom a federal court barred from deportation.
abcnews.go.com/US/19-year-c...
A 19-year-old college student who was on her way to surprise her family for Thanksgiving break was detained at a Boston airport and later deported despite a federal judge's order blocking her removal, according to her attorney. Any Lucia Lopez Belloza, who entered the U.S. from Honduras when she was 8 years old, was about to board her flight to Texas last Friday to visit her parents and siblings when airport authorities told her to step aside, her attorney Todd Pomerleau told ABC News. Lopez Belloza was detained, informed that she had a removal order and then arrested, her attorney said. Hours after her detainment, court documents obtained by ABC News show that a federal judge ordered the government not to remove the 19-year-old from the U.S. and not to transfer her outside of Massachusetts.
