United States fertility rate at an all-time low


"During 1940–2018, the expected number of births a woman would have over her lifetime, the TFR, was highest for women during the post-World War II baby boom (births during 1946–1964). In 1957, the TFR reached a peak of 3.77 births per woman. The TFR generally declined for the birth cohort referred to as Generation X from 2.91 in 1965 to 1.84 in 1980. For the birth cohorts referred to as Millennials (Generation Y) and Generation Z, the TFR first increased to 2.08 in 1990 and then remained generally stable until it began to decline in 2007. By 2018, the expected number of births per women fell to 1.73, a record low for the nation. Except for 2006 and 2007, the TFR has been below the level needed for a generation to replace itself (2.10 births per woman) since 1971."

Given the meteorite's age, it also preserves material that created our solar system, providing a unique look at our corner of the universe and how it formed."

"A lifelong swimmer leapt into deep water near his lakeside home, and was horrified to find himself completely unable to swim. Had his wife not rescued him, he might have drowned. He had recently received an electronic brain implant to control tremors and other symptoms of Parkinson’s disease, and somehow the signals from the device had knocked out his ability to coordinate his arms and legs for swimming. He was one of nine patients, all good swimmers despite having Parkinson’s, who had the same strange, dangerous side effect from deep brain stimulators."

The wildflowers in the book are arranged by both color and blooming date (within color classes), just as you’ll see in other field guides. However, in this guide, the flowers appear as they actually look when you see them from the road."
The book is available here in a PowerPoint presentation.   I particularly enjoyed the descriptive phrases such as "There are several closely-related fleabane species, though few people care which is which," and the "differential diagnosis," such as this for the stiff goldenrod:
Similar species:

A stutterer reprimands a bully

As reported by The Guardian:
Chesley Sullenberger, the pilot who performed the “Miracle on the Hudson”, has told Donald Trump’s daughter-in-law Lara Trump to “grow up” and “show some decency”, after she mocked Joe Biden for stuttering.

Biden, a frontrunner for the Democratic nomination to face President Trump in November, has spoken openly about his lifelong experiences with a stutter.

Lara Trump, who is married to the president’s second son Eric, works for the Trump re-election campaign and spoke in that capacity at an event in Iowa on Friday, the day after the seventh Democratic debate.

“I feel kind of sad for Biden,” she said. “And you know that’s when it’s not going well for him, right, because I’m supposed to want him to fail at every turn. But every time he comes onstage or they turn to him, I’m like, ‘Joe, can you get it out? Let’s get the words out, Joe.’”..

Regardless of how you feel about Joe Biden,” he wrote, “or his chances of becoming the Democratic nominee for president; whether you are a Republican, a Democrat, or none of the above; whether you stuttered as a child or laughed at one who did; whether as a parent you try to protect your own stuttering child from taunts such as those made by the president’s daughter-in-law; these words come without hesitation: Stop. Grow up. Show some decency. People who can’t have no place in public life.”

Trump’s words, he said, were indicative of a “culture of cruelty” which “drives decent people from public service and … makes millions of Americans recoil from politics, and even from participating in our democracy”...

Sullenberger concluded by saying “a speech disorder is a lot easier to treat than a character defect” and telling any children reading to “ignore kids (and adults) who are mean, or don’t know what it feels like to stutter.

An awesome image showing the immensity and solitude of Alaska.

While we're on the subject, I'll mention the book shown at right - Winterdance: The Fine Madness of Running the Iditarod - which I read about fifteen years ago and thoroughly enjoyed. 

About the same time the book was published I was offered an opportunity by a friend to go winter camping by dogsled near the Boundary Waters Canoe Area in northern Minnesota.  It would have involved a couple days of preparation, then several days of dogsledding, sleeping in tents along the trail.  For reasons I can't remember now, I declined the offer.  I think of that missed chance at times like this week when reports of a "solar storm" sent me out into the midnight air for two nights, hoping to catch a glimpse of the northern lights (sadly, they weren't evident at our latitude).

Life is short, and there are always choices to be made.  I was once advised, and am more and more coming to agree, that as one gets older, the regrets one has are most often not about the things you have done, but about the things you didn't do.

Reposted from 2012 because I gave the book a final re-read this past week and once again thoroughly enjoyed it.  What I had remembered most from the first read was the often self-deprecating humor when the author describes his efforts to learn the art of dogsledding (including what his wife described as a "two-skunk night") and his comical start at Anchorage in his first race.

What I appreciated more on the second read were the aspects of the "quest," the bonding that occurs between the musher and his dogs, and the introspection that occurs when someone is virtually alone in the wilderness.

This is an easy read - a couple hours spread out over a couple evenings.

Catastrophism as an alternative to Darwinian evolution


This past week I did a final re-read of a book that impressed me back in the 1980s.  The Great Dying is a deep dive into the Cretaceous-Tertiary extinction created by the Chicxulub asteroid impact that struck the Yucatan 66 million years ago.

Kenneth Hsu is a highly-qualified and award-winning geologist.  For the book's title he has borrowed a phrase now more commonly applied to the Permian-Triassic extinction, but his interest and his life's work centers on the end-Cretaceous one.  He uses the undeniable evidence of the event to argue that major shifts in evolution are often driven by catastrophic events rather than by the progressive accumulation of incremental advantageous traits. 

He's not the first to address this issue.  Catastrophism was offered as a theory as soon as paleontologists discovered evidence of extinctions, was viewed favorably by Biblical scholars, and was later dialed up to 11 by Velikovsky.  It is one of many alternatives to evolution by natural selection.

Massive extinctions are fascinating events to read about.  I've heard some recent podcasts about new findings related to the Chicxulub event that left traces of iridium around the world in a layer of sterile clay.  My understanding many years ago was that the Yucutan impact disrupted the world's climate by producing either global heating or global cooling from the massive ejection of dust and water vapor and carbon dixoide into the atmosphere, and that the dying would have resulted from starvation or heat or cold intolerance.  Recent evidence of tektites half a globe away suggest that the world may have been flash-heated to cooking-to-death-all-exposed-life levels.

In any case, the argument of Hsu and other catastrophists is that these events do not result in "survival of the fittest" but rather "survival of the lucky."  One can't really argue that dinosaurs were "unfit" - they had covered the habitable terrestrial and aqueous world, were carnivores, herbivores, piscivores, and all the other vores.  They flew, swam, plodded, and ran in every non-arctic environment.  And they had survived (and evolved) for 160 million years.  Apparently there was one dinosaur - Stenonychosaurus inequalis - "whose large braincase, stereovision, and opposable thumb hinted at the potential for becoming a race of intelligent beings."  Then they all died within a time frame too short to measure accurately with geological sediment layers.   About 75% of all existing species at the end of the Mesozoic never appeared again - and they have nothing in common as unfit traits except that they were obliterated.

If one wants to say that the surviving mammals or rotifers or water bears are the result of the best "fitness", then that argument reduces down to just saying is that fitness is defined by survival and that you can't predict which organisms are the fittest now because there's no way to know what catastrophe awaits in the future.  The ones who survive will proliferate, perhaps abundantly, and then begin their own gradual evolution and speciation, not because they are fittest, but because they are the first to enter a recently-emptied ecosystem.

Personally, I don't have any difficulty incorporating both catastrophism and Darwinian gradualism into my thinking.  Natural selection is obviously operative even on very short timescales when pollution changes moth populations from white to brown, and catastrophes from floods to fires radically change ecosystems, resulting in new adaptive changes.

One reason some people ardently embrace the primacy of the principle of Darwinian "survival of the fittest" is that they want to apply it to human endeavor, arguing that their race or their culture is the result of natural social selection and other races/peoples are inferior.  And while that stance may be polticially incorrect and seldom expressed quite that way openly, one hears the same argument applied out loud to the business world - that corporations that prosper do so because they are the fittest and they deserve their prominence because they are better than their competition.  Here is Hsu's closing summary:
"We have been competitive; we have exterminated others, both our own and other species, whom we perceive to be interior, or at least of no account; and we would like to feel justified in such endeavors.  But the history of life can provide a scientific basis neither for capitalism nor for socialism, neither for Marxism nor for racism nor for the Maoism of ceaseless revolution.  The opinion that "favored races" are preserved in a struggle for existence was a speculation that has become a dangerous ideology.  We should cease to lend it a cloak of scientific respectability...
I believe we must live without pretending to know who or what is fit and not fit.  Instead, we should embrace the diversity of forms and ways that nourish life itself.  Looking back over the several billion years of our evolution, that is the closest I can come to the Tao of our existence.

For a Westerner, perhaps the essence of my perception can best be expressed by a quote from the Bible:
"I returned and saw under the sun that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favor to men of skill; but time and chance happeneth to them all. "
I've not added this to my "recommended books" category in the blog because it is a detailed longread probably better viewed as a textbook than as casual reading material.  And there likely have been some better books on the subject since this one was published; readers are invited to suggest others.

"Country Life" humor from Punch, part II

Over a period of many years I clipped out selections from the "Country Life" section of Punch magazine and stored them in a "humor" scrapbook. When I hosted parties at my apartment I would invite guests to sit down and try to read two pages while controlling their emotions and not smiling or laughing. I don't recall anyone successfully doing so. Now I'll try posting the pages here in the blog, a couple at a time.

The control of "dot-org" domains has been bought by a private company

From an article written by Esther Dyson in the Washington Post:
One of the Internet’s most trusted assets — the dot-org domain used by nonprofits from UNICEF to your local food bank — is being hijacked. Dot-org, which was built to support nonprofits globally, is being sold to the highest bidder with almost no public discussion or consideration of alternatives...

Dot-org, though, is special. Under the stewardship of the Public Interest Registry (PIR), the organization to which ICANN delegates control and operation of the dot-org domain, dot-org serves the nonprofit community as a trusted partner. Nonprofits provide websites and use email with confidence and peace of mind. Even while business interests captured most of the Internet’s policymaking, dot-org remained protected from profit-driven rulemaking.

Today, though, that independence is under threat. The Internet Society, a nonprofit to which ICANN delegated the duty to host PIR, announced a deal in November to sell PIR and its license to sell dot-org names for more than $1 billion. The buyer is Ethos Capital, a private-equity firm with investments in digital advertising, data brokering and other Internet services...
