Blogcation over

I was sorry to say goodbye to family and friends "up at the lake."  I was serenaded nightly by loons, so I hope I can find some way to embed a 30-second recording of them yodeling.  Not sure how to do that.

I need to recombobulate for a day or two, then will resume blogging after the weekend.

Blogcation

My cousin's place on Girl Lake, Longville, Minnesota.  The cabin is a legacy site, so the setback from the lake was grandfathered (nobody can build this close to the water nowadays).  

No blogging for two weeks - and no curation of comments.  Feel free to comment on old posts, but I won't review them for publication until I get back.

The "cosmic calendar" - depicted visually and verbally

This subject has been filmed before, including perhaps by Carl Sagan? but it's worth emphasizing.  Posting this now so that later I can add extended text from Orbit 13 of Orbital, which has I believe the best text description of the cosmic calendar.

Addendum:  I'll add the text description now so I can quit blogging for a couple weeks.  With apologies to the author/publisher - I really shouldn't excerpt so much, but here goes...

Too many people just can't recognize satire

Embedded above is a screencap from a post on X that I saw reposted on Facebook, where there were thousands of comments, the vast majority of which seriously argued that this is not a walkable community.  Others asked why you would walk miles to a gas station, and some suggested walking seven miles to a liquor store would be a good idea.  These must be the same people who become congressmen believing stories from The Onion.

Lots more similar posts from @bankertobuilder.

The disturbing childhood of R. Crumb

Those who came of age in the 1970s will remember Fritz the Cat and other cartoons by Robert Crumb.  Here is an abbreviated summary of his developmental years:

"One of five kids, Crumb was born in 1943 to Chuck, an enlisted Marine, and Bea, a diner waitress. In the span of a few years, Chuck’s posts took the family from Pennsylvania to Iowa to California, with each new place less stimulating than the last. When the children acted out, Chuck spared not the rod. (He was also suspected of being closeted: in the early Sixties, a family friend claimed to have seen him cruising in a public restroom.) For her part, Bea had already had a baby with her stepbrother when she was fifteen; her parents covered it up by claiming the child as their own. She had a weakness for amphetamines, often chain-smoked in front of the television, and was twice committed to mental hospitals. Robert once found a suicide note she’d left in the family car. His older brother Charles went further than that; he tried to kill himself by guzzling furniture polish when he was in his late twenties. Charles got beat up a lot in high school and liked to smash bottles and slash tires; he never moved away from home and spent his last decades heavily medicated, before taking his own life in 1992. Sandra, one of two sisters, married a close friend of Robert’s named Marty; when she became pregnant, she supposedly told Marty, in Nadel’s words, that “she’d fucked everyone, including the pizza delivery boy, and wanted a divorce.” (Robert experienced his first orgasm while wrestling Sandra when they were teenagers.) Carol, the other sister, seems to have led a comparatively quiet life and keeps to herself. Finally there’s Maxon, the youngest brother, an epileptic who refused to treat his seizures. When he wasn’t assaulting women, he embraced asceticism. “Every six weeks since the late 1970s,” Nadel writes, “he has passed a twenty-nine-foot strip of cotton through his gastrointestinal system, in the mouth and out the anus, a cleansing that takes about a week to complete.”

That passage from a review of the new book Crumb: A Cartoonist’s Life in the current issue of Harper's.

Awesome.  Looking forward to comments from readers.

The ultimate legacy of our lives

"Assuming 128 grams a day and a lifetime in the vicinity of seventy-five years, you’ll leave behind around three and a half metric tons of feces when you die. The volume of your urine will be closer to thirty-eight thousand liters, a bit larger than a standard twenty-foot shipping container and about double the accumulated volume of your flatulence. You’ll have made hundreds of liters of tears, though even for the most emotive of individuals, the portion derived from feelings will represent a minuscule fraction of that number. For all the hullabaloo surrounding ejaculation, the total semen production of even the most alacritous masturbator could be contained handily by a shelf of two-liter soda bottles, and though a period sometimes seems as though it will never end, you could only barely paint a closet with the three or so liters of menses produced during a lifetime. You’ll have made a great deal of mucus, though, close to a hundred thousand liters. And when Atropos snips the thread of your life, the hair from your head, measured as a single strand, will stretch more than three and a half million feet. This is what you will leave behind.

Of course, you’ll leave behind another thing: your body itself. It’s uncomfortable to think of the body in this way, in the same category as feces and hair, but despite the desires of countless theologians, the trajectory of your body’s final journey will be less like the fiery passages of the stars and more akin to those meandering pilgrimages taken by your feces and urine, your blood and vomit and tears. It will become something that must be dealt with, something that must be disposed of. We may disagree over the existence and nature of an afterlife, but not about the stench of rotting flesh...

What, if anything, remains? In the most purely physical sense, your body contains about five hundred megajoules of energy, enough to run a sixty-watt light bulb for one hundred days or to drive a midsize sedan a mile, or, to put things in dietary terms, roughly 120,000 calories, the equivalent of a hundred Big Mac combos. This energy, stored in the form of chemical bonds—namely as molecules of glucose, protein, and fatty acids—will remain intact after you die. It needs only to be converted into adenosine triphosphate to continue its chemical journey in the shape of another. Since no single creature will be capable of digesting your body in its entirety, the scavenging of this energy will take the form of a vast buffet. The glucose in your thigh muscle might be catabolized via glycolysis by a rat while a fungus might hydrolyze the proteins in your skin. The real prize at this feast, however, will be those molecules that most efficiently store energy, your fatty acids, so that the caloric orgy reaches its apotheosis in that fattiest of all your organs, that thing which seemed most you: your brain..."
