Degenerate Matter

Tuesday, 1 June 2010

At Kingdom Kane (a 'blog focussed upon the art of Gil Kane), Mykal Banta has reproduced The Birth of the Atom. a story which contains what I have long regarded as an epitomal sequence of what I call comic-book science: Ray Palmer leaps over a wall in pursuit of a meteor seen in the distance, about to hit the Earth.Ray Palmer excavates a meteor composed of about 1000 cu cm of degenerate matter from a white dwarf star, buried about two feet in the earth. 'So heavy-- I can hardly lift it!'Palmer, holding the meteor, looks at in amazement. 'Puff!'Palmer carries the meteor back to his car. 'Puff!'

As I noted to Mykal, a white dwarf star has a density of about 1 million grams per cc, and the meteor appears to be about 1000 cc, so the whole thing should mass at about 1 million kilograms.

It's not apparent why 1 million kilograms should stay compressed into such a small volume. In the case of a dwarf star itself, the gravitational mass of the star as a whole creätes sufficient force, but this is just a fractional piece of such a star. It ought to fly apart as a terrible burst of radiation. But let's assume that this somehow doesn't happen, that the meteor just stays together in a nifty one-liter piece.

The meteor that creäted Meteor Crater in Arizona was under 30,000 kilograms. Ray wouldn't be excavating the meteor at all; he would have been killed by the shock waves from the impact. Those who later did excavate the meteor wouldn't find it buried just a couple of feet deep.

At the surface of the Earth (which itself masses about 5.97 × 1024 kilograms), this meteor would weigh about 11 hundred tons, but Ray picks it up! He subvocalizes a few puffs, but he manages to carry the thing back to his car! Now-a-days, they don't make cars that can carry 11 hundred tons. I don't think that any grad students can lift 11 hundred tons. And, really, Ray ought to be sinking into the ground, as even if he has big feet and has both feet on the ground he is applying over 7000 kPa of pressure to the soil.

It might be suggested that the meteor, while perhaps of material that were once compressed to a density of about 1 million grams per cc, were subsequently uncompressed, and that what Palmer recovered were only, say, 100 kilograms of material. But I don't know how, then, it would be recognizable as originating from a white dwarf star. For example, the core of the sun compresses matter to a greater density than 100 grams per cc.

And He'd Know Better if He Needed One

D.C. to begin using more-expensive Trojan condoms in HIV prevention program by Tim Craig of the Washington Post, 21 May 2010
[…] D.C. officials have decided to stock up on Trojan condoms, including the company's super-size Magnum variety […]

(Underscore mine.) Actually, the Magnum® variety is not super-sized. It is not much different in size from various other condoms. It is simply marketed in a manner that yields an impression of being super-sized to those who don't actually check the facts — such as journalists. An ordinary-sized Trojan condom is 52mm wide and 200mm long; the Magnum® is 54mm wide at the base, widening to 60mm at the head, and 205mm long. (The Magnum® XL differs in that it widens to 65mm at the head.)

(The Durex® Avanti™, on the other hand, has a width of 64mm along its length. It is, however, only 180mm long, which might be of concern if the condom is being used to prevent the transmission of disease and the anatomies of the sexual partners allow penetration to a greater depth.)

When the subject of condom size is raised, many women and various men with small penes make the point that condoms stretch, so that a regular-size condom can be put on a larger penis. Indeed, but elastic substances produce greater counter-force when stretched farther. The fact that someone might be able to fit a spring around his-or-her cranium (as occasionally condoms are stretched around heads for one reason or another) doesn't mean that one can comfortably wear that spring around one's penis. So larger condoms are quite appropriate for some men.

But, with the Magnum®, Trojan is selling a mere 0.08in in additional width, just 0.2in in extra length, and fantasy.

Self-Policing

Thursday, 20 May 2010

I've written about the topic of self-policing elsewhere, earlier. But I've been thinking of writing about it here, and it arose in conversation to-day.

The term self-policing has multiple meanings, but it usually refers not simply to individuals regulating their own behavior, nor simply to any sort of regulation of own-behavior, but to members of a group acting to regulate how other members of that group treat outsiders. When, for example, one refers to members of a profession engaging in self-policing, one is typically speaking of them taking steps to protect clients against incompetence or dishonesty.

Lots of self-policing is not recognized as such. For example, when a state goes to war, those within the nation who attempt actively to impede the war are engaged in self-policing based on notions of right-and-wrong. Those who actively seek to compel support for the war are also engaged in self-policing, albeït based upon different notions of right-and-wrong.

The American civil rights movement succeeded exactly by persuading a sufficient number of white Americans to act to regulate the behavior of other white Americans; again, it was self-policing. Whites who did no more than insist that not all whites engaged in discrimination were not truly part of the problem, but they certainly weren't part of the solution, and they ought to have been.

And likewise for those in other groups who, instead of self-policing, will merely self-righteously insist that the problematic behavior from within their group is not universal to its members. They are not truly part of the problem, but they certainly aren't part of the solution, and they ought to be. Although a people may be not only technically but meaningfully civilized without self-policing, a society or culture that lacks self-policing is none-the-less less civilized than one with self-policing. And, while we are not entitled to forceably compel other people in-or-outside of our own culture to self-police, we are entitled to demand such in non-coërcive ways, and to look with contempt upon people or peoples who do not self-police.

Everybody Draw Mohammed Day Is Here!

Wednesday, 19 May 2010

To-day, 20 May, is Everybody Draw Mohammed Day. I'm quite disappointed that its founder has retreated; I could not have withdrawn in good conscience, even though my contribution demonstrates that I am pretty poor at working in charcoal: [drawing of the head of a bearded man of Mediterranean stock]

Some people have chosen to draw caricatures, but my objective was simply to violate a grossly illegitimate prohibition. As such, I sought to draw Mohammed. If the death threats become more narrowly focussed on those who creäte caricatures, then I will creäte a caricature.

Somewhere in Chapter 3

Friday, 14 May 2010

After Adam had eaten of the fruit of the Tree, the dog did lick juice from the fruit, but from its flavor decided that the fruit was not food. And so the eyes of the dog were but little opened. The cat did merely sniff of the fruit, and then turned to other things.

The US Constitution and the National Debt

Monday, 10 May 2010

The Confederate States of America went into debt to finance their war of secession. After the war some of their creditors wanted that debt repaid. The United States, on the other hand didn't want them to recover any of their investment, for the obvious reasons. In response to the insistence that this debt not be paid, sympathizers of the Confederacy suggested that, likewise, the debt of the Union should not be paid, for the obvious reasons. Additionally, it was argued that the emancipation of slaves was a taking of private property, so that, under the Fifth Amendment, former slave-owners were owed just compensation.

The North reminded the South who was making the rules, and included the following as section 4 of the Fourteenth Amendment:

The validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned. But neither the United States nor any State shall assume or pay any debt or obligation incurred in aid of insurrection or rebellion against the United States, or any claim for the loss or emancipation of any slave; but all such debts, obligations and claims shall be held illegal and void.

(Underscores mine.)

There's probably someone out there somewhere, even now, insisting that the debts of the Confederacy should be repaid, or that descendants of slave-holders are owed reparations, but those issues no longer have much currency, nor can they be expected to recover currency.

On the other hand, when addressing the debts of the United States, that Amendment included but did not limit itself to those debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion. What remain potentially relevant, then, are the underscored words:

The validity of the public debt of the United States, authorized by law, […] shall not be questioned.

The national debts of the United States cannot Constitutionally be repudiated, without further Amendment. Under the Constitution, they have to be serviced; and, when they come due, they have to be paid.

Present levels of deficit spending are widely seen as unsustainable, and the United States Treasury has begun to pay discernible risk premia, which is to say that a significant part of the market expects that the United States might default. So one question is of how a default might be effected.

In theory, an Amendment could quickly be ratified to permit default, though a significant share of the national debt remains domestically held, which would tend to brake the passage of such an Amendment. Of course, the beginning of the process of amendment would drastically erode confidence in the debt, so that the risk premia would grow dramatically, and the Treasury might find itself almost immediately unable to pay bills, and might remain unable to do so until the Amendment were ratified and restructuring negotiations were completed.

A more likely process would be a Declaration of Emergency, under which the Constitution were suspended, as the federal state worked-out what it could expropriate from whom. (The Constitution makes absolutely no provisions for such emergency suspensions, but we've had a long history of our rulers claiming the power to effect them,[1] and of courts doing little to check such actions.) Again, the United States might be unable to borrow money, but the process of partial repudiation could immediately be brought forward.

Or it might be that the debt were restructured without the consent of creditors. Such a restructuring would, in fact, be a partial repudiation, but lawyers and judges have long proved adept at making distinctions where there are no differences.


[1] With one exception, during each war since the adoption of the Constitution, the President has suspended provisions of the Constitution. That one exception was Madison, who had been the principal author both of the Constitution and of the Bill of Rights.

Words, Meanings, and Intentions

Wednesday, 5 May 2010

When some party attempts to communicate, there are conceptual differences amongst

  • what symbols were transmitted
  • what conceptual content is appropriately associated with those symbols
  • what conceptual content the party desired to convey
Put more colloquially,
  • what someone literally said is one thing
  • what the words mean is another
  • what someone intended to say is still another
though, ideally, perfect agreement of a sort would obtain amongst them.


People who won't distinguish amongst these are a bane. They'll claim that they said something that they didn't; that you said something that you didn't, that their words meant something that they couldn't; that your words meant something that they couldn't. They expect a declaration That's not what I meant! to shift all responsibility for misstatement to the other person. They expect to be able to declare That's not what you said! when it's exactly what you said but not what they had thought you intended or not what they had wanted you to say.

It's of course perfectly fair to admit that one misspoke with That's not what I meant!, so long as one is not thus disavowing the responsibility for one's actual words. I'm writing of those who avoid responsibility by the device of refusing to acknowledge anything but intentions or supposèd intentions.

Some of them are even more abusive, attempting to use That's not what I meant! to smuggle ad hoc revisions into their positions. By keeping obscured the difference between what was actually said and what was intended, they can implicitly invoke the fact that intent is less knowable than actual words, while keeping misstatement unthinkable, so that the plausibility that there was a misstatement cannot be examined.

One thing that I certainly like about the 'Net (and about recording equipment) is that it has made it more difficult for people to refuse to acknowledge what they have or another party has actually said. They'll still try, though. I've repeatedly participated in threads where someone has denied saying something when it's still in the display of the thread. (And, oddly enough, it seems that I'm often the only person who catches this point. I don't presently have much of a theory as to why others so frequently do not.)


Setting aside those who won't distinguish amongst these three, there are people who more innocently often don't distinguish amongst them. I was provoked here to note the differences as they will be relevant to a later entry.

The Colossus Grows Old

Friday, 30 April 2010

It's easy to state the position of most Republicans on the issue of immigration:

  • They want the vast majority of unauthorized immigrants to go or be sent out of the country (presumably back to their home countries).
  • Thereäfter, they want future entry to be determined by some notion of the general interests of those who are already citizens.

It is harder to state plainly what practical policies most Democrats want.

As a practical matter, open borders cannot be reconciled with access to state subsidies of services such as education and health-care, let alone to a more general dole; there simply isn't and wouldn't be enough wealth within the United States. One possible resolution is to allow anyone entry, but to deny entrants any state subsidies; they or private charity would have to pay for everything. This resolution would not satisfy those who have further objections to immigration, but it is in any case a non-starter; when constituent states have tried to limit unauthorized immigrants to emergency services, the mainstream of left-wing activists has denounced the restrictions as racist violations of fundamental human rights, and courts have sided with those activists.

A large number of Mexican-Americans would like other Mexicans to be able to come here fairly freely; fewer would extend such welcome to the entirety of Latin America, and far fewer Hispanic-Americans would embrace such freedom for Asians and for Africans. I doubt that most Hispanic-Americans would appreciate a wave of Eastern Europeans.

(By giving preference to those who already have family members in the United States, present immigration law is designed to mollify both the my people but not those people crowd and those who don't want to compete against immigrant workers. It is much easier to get admittance for a grandmother as such than for an engineer as such.)

Many activists would like an amnesty for those presently in the United States in violation of immigration law. Opponents note that an amnesty now would raise hopes for another later, increasing the incentives for unauthorized immigration; and there is an obvious question of how (if at all) to compensate those who queued legally while recipients of the amnesty entered without authorization. Some critics insist that there would be a significant increase in other sorts of law-breaking, should punishment be waived for unauthorized entry. And, in the absence of an over-haul of entitlement programmes, any amnesty would significantly increase access to state subsidies, in an era where some constituent states are teetering on the edge of bankruptcy, the Federal government is running unsustainable deficits, and a majority of Americans already believe themselves to be over-taxed. Little-if-any response to these objections has come from the Democratic coälition; indeed, many activists on the left explicitly assert a need to give unauthorized immigrants greater access to entitlement programmes.

The President's style of leadership concerning major issues has been to propose rather vague and general objectives, then leave it to the Democratic Congressional leadership to actually formulate practical proposals. He's been pressed to do more than hand-waving on immigration, but he has nothing to say. His supporters cannot hold together and be honest with each other. Many of them cannot even be honest with themselves. And they cannot be honest with the rest of America. Small wonder, then, that the President flinched. (Yet I admit to being momentarily taken-aback when I read what he had said.)

(My own position isn't at all popular either, but it is consistent and I can be honest about it. It's the aforementioned non-starter. I believe that anyone who is not shown to be a criminal should be permitted entry to the United States, but should be denied all net state-subsidies. I'd run an electrolytic current through the Colossus, so that she shined like a new penny.)

Gaming the System

Wednesday, 21 April 2010

My father has a pair of Microsoft® Xbox 360™ systems. He spends a fair amount of time on one or both of them, by himself and with my brother.

(My mother reports that my father's interest in the Xbox developed after I sent to him links to the Rooster Teeth Productions Red vs. Blue machinima videos.)

I have more than once been impressed by video games as programs, and wouldn't mind doing such programming, but I've never been much for playing them, unless one counts Rogue and NetHack as such.

And I really loathe the Xbox controller. It strikes me as a product of path-dependency, rather than otherwise optimal design. The particular path was begun by a controller for the 1983 NES (an 8-bit gaming system with a clock-speed of less than 2 MHz and accordingly limited possibilities), with understandably little consideration as to the effect of the design on the future. Each subsequent controller design was affected by the desire not to impose too much change upon users, and perhaps in some cases by a need for compatibility with existing and anticipated gaming systems. Were controller designers starting with an understanding of the information that players would now want to be transmitted, but otherwise fresh, then the designs would be radically different.

But it discernibly saddens my father that I don't join him on his systems when I visit. So I have purchased an Xbox 360™ wireless controller for Windows and a copy of Halo®: Combat Evolved for Windows, so that I can practice using controllers of that d_mn'd design, with a game of the sort that my father plays. (My computer does not have enough umphf for some of the newer video games.)

I'm also then being compelled to boot-load Microsoft® Windows in order to play the game. So I'm running an operating system that I hate to play a game that doesn't appeal to me to familiarize myself with a controller that I hate. Maybe I'll stop hating the controller. (I sure won't stop hating the operating system!)

I mentioned this matter to the manager of the apartment complex in which I live. She noted that there are far worse things in this world than feeling obliged to play video games. That's certainly true.

And it's even true in the face of something that I didn't mention to her, which is that something about the game — beyond the awkwardness of the controller and the usual objectionability of Windows — adversely affects my mood. Perhaps it's that the fictitious world has been one of emptiness punctuated by violence.
