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;

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...

When I think back to books that seared themselves upon my brain, it was a mixture of form and content [that cast Searing Ray].

I think I read a book one time, some kind of dystopia, where people went to theaters to watch film of people being shot in the water. Author implied this was a bad thing, socially.

Conquistador (Procol Harum song) - Wikipedia

I have 'issues' with this 'plot' summary: en.wikipedia.org/wiki/Conquis... Isn't a museum or public statuary more likely, with the seemingly contemporaneous details mere flourishes of a piqued imagination?

I'm still using the one from @kjhealy.co forked from another starter kit, filled with my own customizations that I no longer understand but am terrified to lose or change. It gives me some satisfaction knowing that the frontier models still are terrible at elisp, however.

"A good grip on the insolubility of the quintic" is a charming phrase I just read on HN. Where else would you find them?

Two irrational (surdic) irritations: innumerate posters mocking some high school student with a near-perfect SAT for not getting into college of choice vs. equally innumerate columnist mocking UCSD for its math placement policies.

Do they have ballot referendums (-da) where you live? Because, I tell you, voting on every millage chaps my hide!

I have a faint resemblance to Steve Spurrier, and I used to get a predictably outraged reaction from freshman at UF when I would tell them that I easily could have coached the team to a victory over Marshall or whoever the first-week sacrifice was.

My main hobby (tennis) gives me access to the opinions of non-academic educated Louisianans, at least on occasion, and nothing seems to matter them to more than coaching buyouts, salary contracts, and what they would do if they were in charge (as it should be).

I know this is very obvious, but all the talk about football coaches is emergent marketing: children watch football to imagine themselves as the players (possibly cheerleaders, band, drunken spectators), adults want to be coaches, refs, announcers, and, most of all, athletic directors.

Speaking of citations, what is going with the extensive Beckett bibliography here: ctan.math.illinois.edu/macros/latex...?

A common, mildly melancholy experience despite my familiarity with bibliometrical precepts is finding a detailed, lucid reading published in a major journal and then noticing it's been cited <5 times, often none at all.

That Carol didn't notice =~ 800m dying shows a lack of midichlorians, at the very least. Wonder how that'll develop.

Sometimes I read about flint-knapping and conclude "that wasn't real."

Collecting: "Right after the free form piano solo, the time signature of the fanfare preceding the trumpet solo is, per bar, 4 4 , 7 8 , 9 8 , 4 4, 7 8 and 4 4, then transitions to a section in 5 8 for 6 bars, then goes into 6 8 for one bar. The song stays in 4 4 after that.[original research?]"

A good day to work on annual evaluation. In "what did I learn" section: "a death yak at the Lair stair will take the Kahlúa out of your coffee!"

If your game had a psychoplasmic tendrils mechanic, perhaps I'd give it a shot.

Thank you. I did not know it. I am temperamentally adverse to utilitarianism, which often maps on to a political disposition that I strongly oppose, so it's a troubling concept.

I thought it was a very lucid review. My interest in these movements relates primarily to their co-development with statistical/probabilistic ideas first and then computational ones. Moral ambiguity and statistical inference, type of thing. The construction of the genius-as-utilitarian.
