How to Milk an Almond, Stuff an Egg, and Armor a Turnip now out as a Kindle

Some time back, my wife and I published our medieval cookbook, How to Milk an Almond, Stuff an Egg, and Armor a Turnip. In addition to making it available as a paperback on Amazon, I also put a pdf of it up on my web page for anyone who wanted to download.

It recently occurred to me that it would get much more visibility on Amazon, and that some people would find a kindle more convenient than a pdf. I put the question to people on Facebook, and quite a lot of them said they would like it as a kindle. 

So I converted my Word document to a kindle, using Calibre, a free conversion program. It's a nice program, and their technical support is fast and helpful. Despite that I ran into a lot of different problems, with the result that the conversion took something like ten to twenty hours, about ten times as long as I had expected. But it's now done and up on Amazon, and has sold thirteen copies in the last two days.

For those not familiar with it, the book consists of all of the cooking material from the Miscellany that Elizabeth and I have self-published for a very long time. It contains over three hundred medieval and renaissance recipes, in each case with the original (or a translation) and our worked out version. In addition there are articles on topics related to period cooking. I assume that most but not all of our customers will be fellow SCA members.

McCabe and the 25th Amendment: Two Puzzles

According to news stories based on statements by Andrew McCabe, he tried to arrange to remove Trump via the 25th Amendment. This raises two puzzles:

1. Under the 25th Amendment, the VP plus a majority of the cabinet can temporarily suspend the power of the President. But the next step is for the President to inform both houses of Congress that he is able to function. He then gets back into power unless both houses vote against it by a two-thirds majority

If two thirds of both houses wanted to get rid of Trump they wouldn't need to use the 25th Amendment, they could just impeach and convict. McCabe's tactic only makes sense if he hadn't read part 4 of the amendment the tactic was based on, which seems unlikely. Am I missing something?

2. "You know those paranoid ideas Trump had that the Deep State was out to get him? Well, we were." That's what the story comes down to. It's hard to see how that doesn't help Trump—which, on McCabe's account, is just what he shouldn't want to do. 

So why did he tell it? The least implausible answer I can come up with is that he wanted to sell his book—even if doing so resulted in four more years of Trump. 

Comments welcome.

The Machinery of Freedom as an Audiobook

I am in the process of recording my first book, The Machinery of Freedom, which I plan to make available on Audible and iTunes. So far I have recorded parts I-III, which include all of the contents of the first edition, and the recordings are now on my web page for comments. If you notice any mistakes, let me know.

One problem in doing an audiobook is footnotes. I have mostly left them out, aside from ones that could be, and needed to be, incorporated in the text. Suggestions on that subject are welcome. Possibilities include:

What I have done, perhaps incorporating more

Inserting all footnotes in the recording, probably as "footnote: ..."

Giving the URL of the webbed second edition in my introductory comments and suggesting that anyone who wants to see the footnotes for parts I-IV can find them there.

The webbed recordings are lower quality than the ones I will use for the final audiobook, 16 kbps instead of 192 kbps, in order to keep down file sizes so as to make downloading easier.

Fairfax v Kavanaugh


One point I have not seen discussed in comparisons between Vanessa Tyson's accusation of Justin Fairfax and Christine Ford's of Brett Kavanaugh is the reason that the more recent accusation is also much more likely to be true. 

For any given woman to invent such a story is quite unlikely. That out of a thousand women with both opportunity and motive at least one would do so is not. There were hundreds, probably thousands, of women who could have told the same story that Christine Blasey Ford did tell—any who, in high school or college, lived close enough to Kavanaugh to have gone out with him or attended a party at which he was present. Any of them who were politically left of center had a reason to invent such a story, since even before the accusation Kavanaugh was being ferociously attacked for his predicted effect on the court. 

Fairfax has admitted a sexual encounter with Vanessa Tyson, the first of his accusers. That drastically reduces the number of women in an equally good position to make such an accusation. Further, there is no obvious reason why Tyson, or anyone else in a similar position, would want to invent such a story—Fairfax is not a conservative Supreme Court candidate or anything similar. Instead of hundreds or thousands of potential accusers with both opportunity and motive, we have perhaps none, perhaps two or three. That makes the odds that the story is an invented one a great deal lower.

Assortative Mating and Increasing Inequality

A thought on inequality, based in part on a point in The Bell Curve.

The authors argue that one effect of a meritocratic system is an increase in assortative mating. It occurs to me that the same effect would be expected from any change that increased the range over which individuals sought mates. The girl in your village who makes the best fit with you is likely to fit less well than the girl in your city who makes the best fit. As population becomes more concentrated, transport and communication better, the result should be a greater pairing of like with like.

That assumes, in the context of intelligence, that smart men want to marry smart women and vice versa. I have just been listening to an audiobook of Heinlen’s Podkayne of Mars, in which it is assumed, by the viewpoint character and presumably the author, that men don’t want to marry smart women, hence that smart women find it prudent to conceal their intelligence. If true, that might reduce or eliminate the effect.

If my line of argument is correct, it provides an explanation of increasing economic inequality, since assortative mating should result in widening the spread of whatever characteristics are being sorted on, and some, such as IQ, are relevant to income.

The Flynn effect is a gradual increase in mean IQ. Has anyone looked at whether variance is also increasing?

Shower Design, Tradeoffs, and Gift Horses

The nice thing about the shower in the hotel room where I recently spent a few days was that the enclosure was quite long, long enough so that towels hung up at one end of it were a safe distance from the shower head at the other end. Also, and more important, long enough so that I could use the shower control at one end of the enclosure while a safe distance from the water at the other end whose temperature I was adjusting. That eliminated the usual problem of getting frozen or scorched while getting the water to my preferred temperature.

The not nice thing about the shower was that it took a long time for the temperature of the water to respond to a change in the control, which made the whole process of adjusting the shower to my preferred temperature more difficult than usual.

It eventually occurred to me that these two features were connected. The farther the control is from the shower head, the longer the pipe between them. The longer the pipe, the longer it takes for the changed mix of hot and cold water to get from the control to the shower head, hence the slower the process of adjustment. The feature I did not like was part of the cost of the feature I did like.

This is one example of a general point. Consider any system—a shower, a car, the human body—that has been optimized. If changing the system in some way, in my example moving the control farther from the shower head, produces a benefit, it must also produce a cost—otherwise the change would already have been made in the process of optimizing the system.

The human body has been optimized by evolution. But the purpose it was optimized for, reproductive success, is not my purpose. Hence there might be changes to be made that are to me unambiguous improvements—dollar bills lying on the pavement to be picked up. Still, it is prudent to suspect any obvious improvement of a downside. 

Many years ago my father decided to stop using the phrase "there is no such thing as a free lunch" on the grounds that it was not literally true—consider consumer surplus and producer surplus. If someone pays me a thousand dollars to give a talk I would be happy to give for free, I have just gotten a thousand dollar free lunch.

His substitute: "Always look a gift horse in the mouth."

Concerning Governor Weld

I recently attended an event at which Bill Weld, who was the vice presidential candidate of the Libertarian Party in 2018, spoke. I learned two things:

1. He is not a libertarian
His solution to the problems of technological unemployment was some sort of government retraining program. 

His view on immigration was that we should have a guest worker program and issue more work visas. There was no suggestion that we should be more willing to accept immigrants.

2. He does not understand economics
His argument for free trade was that it would benefit the U.S. because the U.S. has a very productive economy—he wasn't very specific, but it sounded as though he meant that we had advanced technology, productive workers and the like. That is a reasonable position in terms of 18th century trade theory, according to which strong economies benefit from trade at the cost of weak economies—in the old version, by a trade surplus which results in the strong economy accumulating gold and so becoming richer. It makes no sense in terms of modern trade theory. 

I can well believe that Weld has, for a Republican politician, relatively libertarian views of social issues. But, on the evidence of his talk, he ought not to be a LP candidate for any office. That is a matter of some concern since it sounds as though he hopes to get the presidential nomination in 2020.

The event I heard him speak at was Libertycon last weekend. I expect the talks given there, including his and mine, will at some point soon be webbed, so you can listen to his and see if you agree with me.

I have not yet seen a video of Governor Weld's talk but someone has put up a video of mine.
