Retreating from Fake News: The Example of Dunkirk

If you're interested in history, (and a family that made film history) or if you're interested in how events get reported during and after a war, then you really should read  Alone: Britain, Churchill, and Dunkirk: Defeat Into Victory by Michael Korda. For me, tt crystallized certain aspect of British history, the country's view of itself in relation to the rest of Europe, and what was highlighted in films of the WW II. Then, of course, there is the issue of how you truth can be more effective at boosting morale than false propaganda.

Class divisions was not altogether absent from British consciousness, Korda notes, despite the attempts to put differences aside to work together:
The spirit of wartime unity between the rich and the poor was not altogether a fiction, but it was nothing like as strong as it became portrayed later on in British propaganda, let alone in films and eventually television. ... British class warfare was ever so slightly suspended during the war, but by no means eliminated. (451)

That particular issue is at the center of the book that was quickly adapted into a film, both with the title  This Above All.

As for the position the Brits saw for themselves within Europe, it is in the book's title. Though the country started its involvement as an ally to others, the big shift it found at Dunkirk was that it was free to focus on its own needs in the war, a feeling that Korada finds repeated in the Brexit vote: 

King George VI spoke for the whole nation when he wrote to his mother Queen Mary after the fall of France, 'Personally, I feel happier now that we have no allies to be polite to and to pamper.' Dunkirk is not unrelated to the emotions of those who demanded 'Brexit,' the British exit from the European Union in 2016. There was a national sense of relief in 1940 at leaving the Continent and withdrawing behind the White Cliffs of Dover. (p. 461)

To return to another film of the time, They Met in the Dark features the song, "Toddle Along" at least three times. The lyrics stress exactly what the British felt got them through the war, carrying on, even when the going gets tough.  This is what Korda finds in the experience of Dunkirk and why the truth worked better than any lie could: "Churchill did not need a propaganda minister like Joseph Goebbels -- he was his own best propagandist, and his instinct that the British would rally when their backs were to the wall was proved correct." (432)

The British press embraced that approach, too, and that is why even a retreat could be seen not as a loss of honor but a symbol of the nation's resolution:

By now the British press was finally reporting on the Dunkirk evacuation with relative frankness." He cites the description of the withdrawal with a description of the "difficulties" involved. Then he say, "The piece marks a significant change from the Ministry of Information previous policy of manufacturing good news for home consumption and downplaying disasters, and also the first step in in the transformation of Dunkirk form a humiliating military defeat into a proud national epic even as it was taking place. 'Grin and bear it' might have been the new motto fro Britain, in which the ability 'to take it' rather than any significant victory, became a source of national pride, and even optimism." (439)

A Celebration of Rodin

As 2017 marked the 100th anniversary of the death of the most famous sculptor to emerge fromthe  19th Century,  I recently got a double dose of Auguste Rodin. His work was the subject of a special exhibit both at the Met and the Brooklyn Museum. The former closed on the fourth, but the latter is to remain open through April 22.
The Burghers of Calais

It's worth seeing, not because you can't see these Rodin pieces in other exhibits but because of some of the insight it offers. For example, there's a video that shows the process currently used for casting in bronze that still uses lost wax as it did in Rodin's day, though it also incorporates some modern materials that would not have been been accessible to him.

But the one part of the exhibit that made the biggest impression on me was the account of Rodin's early art education. When he was 14, he began his formal art eduction at  the École Impériale Spéciale de Dessin et de Mathématiques – known as the “Petite École," to distinguish it from the   the top school, the École des Beaux-Arts. Rodin applied to that school at 17 and was rejected -- not just once but three times.

It's an amazing thing when you think about: the biggest name in sculpture in his day was seen as unworthy of the best art school. It's possible to infer a great many things from this about the limits of expert knowledge in terms of predicting success, self-awareness of talent that rises above the assessment of others, or even the possibility the true achievement is not a matter of what one is taught but what one learns to do on his own.

Once in a Blue Moon

Super Moon image from

Tonight we will have a Super Moon, as we will next month and the month after that. But the third one is special because it  will also be lined up for a lunar eclipseBut wait, that's not all that's special about the January 31, 2018 full moon. It falls under the designation of a Blue Moon -- at least in one sense. 

"Once in a blue moon." How often is that? about every 2 1/2 years, though whether you'd say 2.5 or 2.7  depends on which definition you use for blue moon, .

From the time I looked it up some years ago, I considered the blue moon to refer to the second full moon in a solar calendar month. (Obviously, lunar calendars are designed to have only a single full moon in a month). However, today I looked it up and found that it also had another meaning that is a bit more precise, though not as commonly used today.

The older meaning defines a Blue Moon as the third full moon in a season that has four full moons. Called a seasonal Blue Moon, this occurs about every 2.5 years, according to NASA. Why the third moon? There are roughly 29.5 days between full moons, making it unusual for two full moons to fit into a 30- or 31-day-long month. 
Accordingly, what fits a blue moon definition in one sense may not fit it another. The seasonal blue moon last occurred on May 21, 2016. But a blue moon measured by month rather than by season can only occur at the very end of the month, and that is said to occur about every 2.7 years.

Here's the infographic from:

This particular terms has evolved into multiple meanings that deviate quite a bit from the strictly astronomical. link brought me to :, which traces the terms through various meanings, including some specific to songs. The earliest it finds is an expression of absurdity that then came to mean never:

like saying the Moon is made of green cheese. Both were obvious absurdities, about which there could be no doubt. "He would argue the Moon was blue" was taken by the average person of the 16th century as we take "He'd argue that black is white."
 The concept that a blue Moon was absurd (the first meaning) led eventually to a second meaning, that of "never." The statement "I'll marry you, m'lady, when the Moon is blue!" would not have been taken as a betrothal in the 18th century.
 Then there were times when the moon actually appeared blue, as a result of huge amounts of ash in the air from volcanoes or fires.
So, by the mid-19th century, it was clear that visibly blue Moons, though rare, did happen from time to time — whence the phrase "once in a blue Moon." It meant then exactly what it means today, a fairly infrequent event, not quite regular enough to pinpoint. That's meaning number four, and today it is still the main one.
However, from an astronomical point of view, the blue moon did come to mean something more specific, though the way we tend to use it today -- the definition I taught my own kids -- seems to find its roots only as far back as the 20th Century. 

One striking fact for those of us who are familiar with lunar calendars is how the frequency of blue moons dovetails with leap months, namely 7 times in every 19 year cycle. The Chinese calendar adds a leap month about once every 3 years, and the the Jewish calendar is set to haves 7 leaps years every 19 years.

Halloween economics, or what your view of trick or treating says about you

This is uncommon for me because it is an  an argument in memes. I started out posting this on G+, but that platform is very bad for featuring pictures. So I decided to put it here.
Disclaimer: I don't do Halloween and find the threat implied in the whole trick or treating approach to emulate an extortion racket rather than a sustainable economic system of any kind.

A few years ago, I came across this cartoon:

 One on the same theme was this:

 This year someone posted one that tried to go the other way, namely that trickle down economics withhold candy:

That image is actually not nearly as effective as this one:
or even this one:

I'm not here to defend trickle-down economics as a system, but as I was thinking about the various memes, I had this epiphany: Socialism is the ultimate trickle-down economic system. You allow a single organization to take individual wealth in the form of high taxes and then distribute it as it sees fit. That is exactly the idea of this illustration:

In fact, what would happen is that while taking the candy that is supposedly to be redistributed, all the hands that pass it on drop some or deliberately transfer some to their own pockets. That is an inevitable cost of such systems of distribution. 

Of course, extreme positions are just that, and there are many Republicans who are not in favor of trickle-down economics, and many Democrats who don't embrace Socialism. Each side likes to show the most extreme form of the other while ignoring its own.

But anyone who presents the notion of fairness being that people do reap the fruits of their labors as a new-fangled Republican idea is ignoring literature that dates at least as far back as oh, 600 BCE or so, when Aesop's fables were composed. You can read The Ant and the Grasshoppper  online to understand how deeply rooted that sentiment is in culture. You can read also read  the 1918 version of The Little Red Hen online.

That story came up in one M. Sott Peck's books. He said that he had first considered it unChristian because it seemed to indicate a lack of charity, but he came to realize that the lesson of self-reliance, the obligation to do what one can  applies not just to material things.

Missingness at the Museum

Explanation on the title: Missingness is the term for missing data. I may come across it more than
most people because I've read a lot of blogs on data scraping projects. It occurred to me that it really fits the context for this post.

The museum in question is the AMNH, which is world-famous for its dinosaur exhibits, though not so famous for its pricing structure. This is just one aspect of missingness in place.

The lines to purchase tickets get fairly long at this museum, though this past Sunday was not nearly as bad as another summer Sunday in which the line extended outside and around the block. Perhaps the special exhibit on mummies is not such a great draw. (BTW if you are interested in mummies or anything else Egyptian, you really have to take a trip to Brooklyn to see the exemplary collection of the vastly underrated Brooklyn Museum.)

I'll talk briefly about the problem with pricing information because it is related thematically to missingness, though it is not my main point. As I said, the lines to pay get very long despite the fact that there are various options to purchase tickets without waiting on that line. They include buying them online and buying them at the machines right next to the lines in front of the human cashiers.

On this particular trip, the family behind me on line made two attempts to purchase tickets via machine and then gave up and returned to the line. I noticed only one group that got off the line, purchased the tickets there, and then went straight in. Why is that? Wouldn't everyone want to cut out the wait time and go straight in?

There are a number of reasons why people persist in waiting for humans, but the primary one seems to be confusion. The entrance to the museum offers various ticket levels, from basic, to plus-one, to all-inclusive. Those prices themselves also vary by age and status: adult vs. student and child. But there are two additional factors that complicate the selection even more: One is that some of the "specials," which include both temporary exhibits and films call for times entry. The other is that really the basic admission price is supposed to be "pay what you wish" just like at the Met. However, any time you add on any special, the basic "suggested" price is rolled in.

 You may be willing to forego the specials to knock down your basic admission price from $23, but that's not an option you have when you pay at the machine. It will only accept full payments. It also will not issue you a ticket for showing your Bank of America card on the first weekend of the month. Yes, this museum is among the ones that participate in the Museums on Us program, but if you didn't check this out on your own, you'd have no way of knowing it from your visit in person. Consequently, it seems that people rarely take advantage of the program. In addition, due to the pricing structure in place, the museum does not allow visitors to count the Museums on Us entry as covering the basic cost and allow for an add-on price just for specials, something other museums do allow.

Given the fact that most of the people in the line appeared prepared to pay full suggested amounts, though, it becomes clear to me that they either don't realize that the machines will help them complete their transactions faster or that they want the person to provide information and guidance on the profusion of alternatives available. This is a major flaw in informing the public about how thing work there ahead of time in order to expedite entry.

Now to the main point of missingness, which some people fail to grasp altogether: the missingness in basic numbers that are accepted as the basis of data.

On this trip, we took a guided tour of museum highlights (though we've seen them all before). This guide included a stop in the Hall of Ocean Life, pointed out the blue whale (which you really can't miss) and spoke about how scientists come up with the population numbers now versus what they were in the past. He explained that in the past, when whales were hunted, the numbers were a function of the number killed with an extrapolation for how many must still be out there. Now that hunting whales is illegal, they use other methods to come up with an estimate of the numbers, and so they conclude that the population has diminished.

Now, I recall years ago reading about people who used a similar method to justify catching and killing wild mustangs. They figured that there were several that they didn't see for each one they did. At the time, that approach came under fire from those who considered it to favor the hunters by allowing them overstate the numbers. So if the same was the case for whales, the numbers estimated in the past were likely overstated. Even if there were not, comparing that system of counting with a count that is based on completely different assumption of counting is the proverbial comparison of apples to oranges. In other words, you're mixing two completely different systems with their own sets of missingness to come up with conclusions about numbers, and that is both inconsistent and misleading.

There is a great deal of guesswork in science. Certainly, the guide admitted this in showing the Titanosaur. Not only is it not the actual fossil but a 3D printed replica, but the replica head is based off of a completely different fossil because no head was present. we see things put together as one and assume that they are accurate. But that is often not the case, so we have to bear in mind that even visualizations that appear compelling may not reveal the whole story of the data. Misssingness  can be dealt with, but one has to know which approach was taken and whether that solution contributes to better understanding or pushes to a particular outcome that is not truly objective. For true scientists, getting things to fit alone is not the answer. That's why you see reworkings of dinosaurs exhibits every once in a while.

My take on "Wait, What?"

This is not an actual review of James E. Ryan's book Wait, What?: And Life's Other Essential Questions. You can read 70 or so of those on Amazon. It's just some of my impressions, the kind of things that my husband would likely dismiss as nitpicks.  He's the one who told me to read the book after he finished himself today. I agree it is a good read, though I wouldn't consider it really life-changing.

Here's my most nitpicky nitpick: it's about a question marks. The book is set out as an exploration of 5 essential questions, and most are set as such like the question in the title. Among them is a paired set: "I wonder if .../ I wonder why..." He believes those are essential to remaining curious and engaged in life, and I do agree with the thought. I just don't agree with the punctuation that he opted for. He placed question marks after each of them, and I would punctuate them as statements because they are not really formulated as questions but as assertions about what one is thinking about.

There is a way to set the equivalent as a question, and that would be, "What would happen if ....?" or "Why does ...?"  Those are expressions of curiosity that are about the things happening rather than how one feels about them -- wondering.

He brings up that kind of curiosity as resulting in positive benefits in recounting the story of finding his birth mother. It's a nice story, though I didn't really find it as surprising as he made it out to be. What actually did surprise me is that he could claim credit for his pursuing this out of curiosity when he admitted to being perfectly content not to find out until he was 47.  I would think a really curious adopted child would have thought about finding his mother at a much younger age.

And now my final nitpick, which is not really a nitcpick but an understanding of reality that eludes the author. One of the key questions is "Could we just...?" He presents that as how his wife gradually won him over to considering having a fourth child. Now here's the thing: generally if a woman is the one who really wants the child-- barring fertility issues -- it will happen. The odds of his thwarting her ambitions in that area were slim to none. In that area the mother's wishes carry a lot more weight than the father's, so it was not really a question of if but merely of when he would agree with her.  In retrospect his agreement extends to her observation that until then the family did  not seem complete. But in reality, parents (who are not averse to being parents)  would feel that way about any child, whether it was the first, second, third, fourth, fifth, or even twelfth, as the case may be.

In terms of really useful advice, I'd say the sections on asking people how they want to be helped and the insight he gained from being shown what to do by a girl named  Cindy are worth noting.

History in Einsenhower Park

On a visit to Eisenhower Park, I went into the the Veterans Memorial section. You can read about it here. Some have distinguishing features, like the one with an attached helmet pictured below:
Others are reminders of some aspects of history that are not included in standard curricula on WWII, like the memorial to the 4 chaplains. 

picture and text from
The information on the memorial is the following:

To learn more about the 4 Chaplains, read this: While there are over 300 memorials to their self-sacrifice, it appears that no one has ever dramatized the event.

Should you find yourself in the vicinity of the park, you can see the various memorials in person. They now extend recognition to those outside the usual parameters of army duty that were victimized,  including the "Comfort Women."
