Thought experiment: You know these two people who are perfect for each other and should marry and form a single household. They don’t know each other yet, but the truth is, the moment they see each other they will fall in love and instantly want to be married forever. Unfortunately, they are living in two very different places. One is living on a permanent human colony on Mars, the other is in a penitentiary in Russia serving a life sentence. Getting them together is going to take a LOT of work.

But, once they are together, they will, as stated, become one, in a sense. So, you organize a meet-up. It is in a house that is for sale, and the real estate agent and closing company are there, so all it will take for the happy couple to have their own abode is a simple signature. There is a wedding officiant in place, and witnesses, so their marriage will also be a single set of signatures. You have had two moving companies go to each of their respective earthly US-based households where all their stuff has been stored, and that stuff is now ready to be moved into the house. All you need to do is get them into the living room of this house.

Then, you get them together. Never mind the details as to how, but it works. They fall in love on first sight, instantly sign the marriage certificate and the closing documents, and movers move all the stuff instantly into their new home. They are now inseparable.

But there is one problem. They have two blenders.

And two Crock-pots, and two electric can openers, and two couches and … well, it goes on and on. If two households are going to merge, some stuff has to go.

Now, take yourself out of that quaint and seemingly improbably metaphor and imagine that when they pack up all the stuff that is duplicated to bring it to Goodwill, all that physical material turns into energy, with the formula predicting the total amount of energy being E = MC2, where M equals the combined mass of the extra blender, extra couch, extra everything else.

There are two sets of forces relevant to nuclear fusion. One is the set of electrostatic forces that keep atoms from getting too near each other. Without that energy there would be nuclear fusion going on all the time. This repulsing energy is the problem in our parable of lack of propinquity, with one of our ideal couple being on Mars, the other being in a Russian prison. These two people are not going to get near each other unless those overwhelmingly difficult problems are solved. The nuclei of two atoms are not going to get near each other unless the electrostatic forces are somehow overcome.

The other force is the strong attractive nuclear force that causes protons and neutrons to bind together in the nucleus of an atom. All you need to do to get this attractive force, represented in our parable by love at first sight, to combine the atomic bits is to get the nuclei near each other, nearer than the electrostatic forces would normally allow. There are a few ways to do this. In an ideal world, you just push them together using some sort of magic pushing wand, but such a wand does not exist. The way the Lawrence Livermore lab does it is to heat the atoms up using lasers, so they are bouncing around so much that kinetic energy pushes some of the nuclei nearer than electrostatic forces would usually allow. The above outlined parable could have used, instead of overcoming the impossible distance to bring the couple together in their future living room, the dance floor of a techno-pop rave. (But there would be other problems with that analogy.)

Forget about the needed energy for a moment, and just think about the atoms/people and their stuff. The atoms are made up of protons and neutrons, and when they are combined, there has to be just the right combination of protons and neutrons or else the fusion of two nuclei will not have an extra blender. There are some combinations of neutrons and protons that will take in energy rather than put out energy. Starting at the lower end of the Periodic Table, most combinations, if you could get them to happen at all, would put out energy (extra blenders and Crock-pots), until you get to a certain point, then the atoms if combined would take in energy. Certain combinations, given important measures of the electrostatic forces and the makeup of the atomic nuclei, would be easier to make happen, and others are more difficult. The details are very technical and very weedy. Suffice it to say that decades of research indicates that a certain combination of Hydrogen atoms, including different Hydrogen isotopes (different isotopes have slightly different bits in the atomic nuclei) can work, while others not so much.

Hydrogen, the lightest element and simplest atom, normally has one proton in its nucleus, and one electron. Since electrons often interact with the rest of the world by taking short or medium length trips to visit other atoms, a hydrogen atom is, essentially, a proton that at any given moment may have a sort of open relationship with an electron somewhere. Deuterium is a form (isotope) of hydrogen that has the usual one proton plus one neutron. It is heavier than regular hydrogen, and is a stable (not radioactive) nucleus. It is also very rare. Something like one in ten thousand hydrogen atoms is Deuterium. Tritium is a special form of hydrogen that has one proton and two neutrons. This isotope of hydrogen is radioactive. As a radioactive element, it decays into an isotope of Helium (releasing beta energy) with a half-life of about 4,500 days. Tritium is produced in a nuclear reactor (there are several methods) so it can be used for scientific purposes.

The fusion reaction that works best is combining a nucleus of deuterium, with a nucleus of tritium. The result is the nucleus of a helium atom (two protons and two neutrons). So, one neutron and one proton plus one neutron and two protons equals two neutrons and three protons, but the helium atom does not use that extra proton.

That extra proton is the extra blender, except it is not a blender, but rather, energy. (I’m oversimplifying here a little. Some of the energy is alpha radiation, some of it is in highly energetic extra neutrons which are captured to heat up an appropriate substance). The amount of energy released from one such reaction of just the two hydrogen atoms is about 1.9516042893337081e-19 horsepower. Obviously, in an actual fusion reactor, gazillions of atoms would be combined every second. The extra energy produced in in the latest experiment at Lawrence Livermore was about enough to bring five gallons of tap water to boil. In an actual fusion power plant, the energy produced by fusion would be used to heat a metal or liquid, to run a turbine to produce electricity, with some of the waste heat inherent I this process (close to half) possibly being put to some use as well.

The radiation produced from a controlled fusion reaction is short lived, and/or will affect only a small amount of material which is easily handled. The reaction does not produce any radioactive material with a long half-life, or that is toxic (both of those problems result from fission nuclear reactors of which we use many to produce electricity). In theory, deuterium can be “mined” from water, and this is fairly routine. Tritium is produced from nuclear reactors of the common fission type, so when people tell that using fusion reactors to produce electricity at a commercial scale does not produce long lived nuclear waste, check your wallet. The tritium production required to feed a large scale fusion industry will require fission reactions, which do produce this waste.

Prior to the latest Lawrence Livermore success most experts, when asked how long the first fusion reactors might be available, have typically said “I don’t know, maybe 40 years.” With this result, the best realistic estimate is probably the same. The big problems with using fusion have yet to be addressed. The reactions that happen now are ephemeral. The reaction itself can ruin the equipment used to make the reaction, and produces a byproduct in the form of extra elemental dust, as it were, that has to be removed instantly or it ruins the reaction. These are surmountable problems, but not easily fixed, and the short term prognosis is uncertain at best.

To understand what has to happen next, let’s try another analogy. Let’s say it is 1800, and someone has the idea that blowing up gasoline or kerosene can move something. So they invent a “car” that has cans of flammable liquid in the back. When a can is ignited, it causes a great explosion that moves the car forward a little. That kind of works, but is not ideal. The better way would be to somehow control the explosions, capture the kinetic energy, and convert that into turning wheels. In theory, that is possible, but in 1800, the metals, electronics, and other materials needed to accomplish this are about a century away in the future.

Today’s fusion experiment is to a future fusion reactor what a 19th century steam-punk submarine imagined in fiction is to a modern attack submarine. Quaint, at best. But hopeful and very cool. Cool in a hot-fusion kinda way, but cool.

Dear Abraham Lincoln and Fredrick Douglass,

You are reading this in 1860, and I’m writing from over a century into the future. Just wanted to let you know that there is a run-off election for US Senate in Georgia (we now elect our Senators with a popular vote in the state). One of the Candidates is a Democrat (he is the incumbent) and the other is a Republican. Both are Americans of African descent. The Republican stands with all of the values of his Republican party, and that is how we know he favors White Supremacy, anti-Semitism, limiting the right to vote, and the destruction of Democracy in America. The incumbent (the Democrat) strongly favors democracy, equity, and wide spread voting rights.

As it stands, the chance of either of these men winning this election is best estimate as 50%-50%.

Sincerely,

Person from the Future

Never let it be said that I won’t give the devil his due. Though I prefer not to.

Michael Crichton wrote some very good books, some even being candidates for having been transformative in the world of science fiction. He wrote Jurassic Park, after all. When I was in graduate school, Crichton was on Harvard’s “Vising Committee,” a gaggle of notables with some credentials who provided wise oversight of things, including the Anthropology Department. During this time he hob-knobbed with my at-the-time best friend and advisor, Irv Devore, so I was constantly hearing stories of how movies are actually produced, and such. Crichton was generous. A significant part of my graduate research in what is now PR Congo was funded from his pocket (along with NSF and other funds). Interestingly, the field site I worked at, along with a few dozen other scholars over a decade and a half, seems to have served as a model for much of the framework for his novel, Congo. We did not have odd apes or missing jungle fortresses, but we did experience many of the other things in the book, including pods of hippos, corrupt customs officials, and various jungley things.

Then Michael started to go off the rails. Or, maybe, he started to rub against a third rails (racism and feminism) and caught on fire, in a bad way.

In 1992, he wrote Rising Sun, which touched on Japanese-American relations and contrasts. It might have been insightful and informative. Or, maybe it was a poke in the eye to an emerging American liberal philosophy. One review noted, “he knew Rising Sun would ruffle feathers, the vehemence of the reaction came as a surprise. Challenges to his economic premise – that the United States is selling its future to Japan – failed to materialize. Instead, he recalls with obvious annoyance, American critics labelled him racist.”

We now, of course, recognize eye-poking “I was only asking questions” racism for what it is. Looking back, it seems a little like Crichton helped invent that. Indeed, Crichton’s published response to this criticsm, noted in his AP obituary (oh right, should mention that: he’s dead), included “because I’m always trying to deal with data, I went on a tour talking about it and gave a very careful argument, and their response came back, ‘Well you say that but we know you’re a racist.'” The Wikipedia article on this book, from which I liberally steal the quotes I’m using, notes that “Crichton has gone on record as saying that he intended his novel to be a “wakeup call” to U.S. industry and that he is more critical of the United States than Japan.”

The movie Rising Son met mid-level reviews, and re-ignited the discussion of anti-Asian racism.

Then Crichton really stepped in it when he wrote Disclosure in 1994. This was in a way the reaction by the established patriarchy to the very very early days of the #MeToo movement.

An all too common story is that a man rising in the ranks of power has some sort of initial relationship with a woman, he then exploits her and tries to force her to do his bidding, possibly in a sexual relationship, possibly in a professional setting, or possibly both. This is one of the things HR rules were designed to address.

In Disclosure, Crichton takes this issue head on as the central theme of the novel, but he reverses the sexes of the protagonists, and ends up with the rising woman harassing the poor hapless man. Of course, that happens. But that is an unusual reversal. Unusual reversals are great material in a novel, right? So when Crichton dreams up this scenario for his novel, later made into a movie, he is just being a clever author, right?

Well, one reviewer would not agree with that:

Towards the end of my review of Rising Sun, I said, “Michael Crichton was kind of an asshole, right? I’m not off-base in saying that?”. With his follow-up novel, Disclosure, I can, without reservation, firmly assert that I think Michael Crichton was unquestionably an asshole.

God. Fuck this book.

My memory of the reception of this book, and the movie made out of it, conforms to this review. (I quickly note that the current Wikipedia page on Disclosure does not fully grok this problem. Any Wiki-writers out there want to look into this?)

Then in 2004, he went and wrote State of Fear. This novel was structured as a sort of documentary, with graphs and data and footnotes, and is a clear and absurd counter-argument over the reality and importance of global warming.

State of Fear was widely criticized by the community of climate scientists, scientific organizations, and science writers. To give a flavor, I’ll quote my friend Chris Mooney:

In the end, State of Fear bears little resemblance to Crichton’s most successful sci-fi thrillers, like Jurassic Park and The Andromeda Strain. Instead, it’s far more reminiscent of Disclosure, Crichton’s perverse attempt to address the issue of sexual harassment in the workplace by focusing on a case in which a woman harasses a man, rather than vice-versa. Similarly, in State of Fear the specter of a vast environmentalist conspiracy—a problem even less significant than sexual harassment of men by their female superiors—gets trumpeted while real concerns (climate change, for instance) get scoffed at. By the book’s end, one can only ask: What planet is Michael Crichton living on? Because this one is clearly getting warmer.

God. Fuck this book.

Crichton was not only on Harvard’s visiting committee, but he had been an anthropology major in my department, and his undergraduate senior thesis was to eventually turn into a novel, one I strongly recommend. That novel, Eaters of the Dead, was his 14th novel by most accounts, but it was really written far earlier as the thesis.

Published just before Eaters, was “The Great Train Robbery.” It is that novel to which I refer you now. The term “great train robbery” is confusing. There were more than one great train robberies. This one, the one in the Crichton novel, happened in England in 1855. Because the event, which really happened (and was known at the time as the “Great Gold Robbery”) involved the paraphernalia of burial of the dead, Crichton goes deeply into that practice as it was in the mid 19th century. The problem was, dead people regularly came back to life in those days, owing mainly to the preponderance of Type II errors in estimating a person’s live vs dead status. For that and other reasons, I found the novel really fun and interesting to read.

So all this leads us to this: At the time of this writing, and probably for about a day, the Kindle version of The Great Train Robbery is available cheap, for two bucks.

Minnesota is the only state with a divided legislature, and with “off year” election syndrome, it is possible that we will turn all red this November. As one of the few pro-choice island states in a sea of red misogyny, not to mention anti-climate change and anti-gay and anti-trans and all the rest of it, we need to not only stay not-red, but even better, get all-the-way-blue!

Cheap: Marvel Myths and Legends*: The epic origins of Thor, the Eternals, Black Panther, and the Marvel Universe, Kindle edition, by James Hill might be necessary background reading if you care about the origins of Thor, The Eternals, Black Panther, etc. If you use primarily a Paperwhite Kindle, I would not recommend this book. If on the other hand you typically read ebooks on your computer using an open-source ebook reader or the like, or a Kindle Fire*, then you may enjoy the graphics.

If you pull the trigger of a rifle and it shoots, and then you have to add a new bullet to shoot again, you might be firing an old fashioned weapon (that may not even be a rifle, technically) and you are probably a hobbyist.

If you pull the trigger of a rifle and it shoots, and then you have to wiggle a metal object around to move a bullet from a storage area within the firearm, into the chamber from which it can be shot, you are using a non-automatic rifle, and you might be living in the old days (as a soldier) or perhaps you are a hunter, because many excellent hunting rifles work this way. It is also possible that you are a sniper of some kind, depending.

If you pull the trigger of a rifle and it shoots a bullet, and then you pull it again and it shoots one more bullet, and so on, with no additional wiggling of metal parts, you are firing a semi-automatic rifle, or at least, a rifle in semi-automatic mode. This is the ideal rifle for accurately hitting several targets, and if the rifle has a couple of additional design features, it may be the ideal rifle for killing the maximum number of people in a given killing bout.

Like for instance, a classroom full of students or a church full of worshippers or a grocery store full of shoppers.

If you choose, instead, to fire a fully automatic rifle in that school room, church, or grocery store, then you are being a firearms idiot. A rifle on a fully automatic setting fires a lot of bullets all in a short time when you pull the trigger. Most of the bullets will miss their targets, and you will run out of bullets really quickly. The students, churchgoers, or grocery shoppers will duck out of the way, and then when you are out of bullets they will (hopefully) swarm you and rip out your liver.

In fact, an automatic rifle is not really designed, while in full-auto mode, to fire at targets, so much as it is designed to fill the air over and near a target.

Does this seem wrong to you? If so, that could be because you, as a non-gun nut, have fallen into a trap frequently set by gun-nut trolls.

You may ask, if a fully automatic rifle is not an effective means of killing school children, then what kind of rifle should I get for that job? (If you were actually thinking that, call 911 and turn yourself in.)

The misconception arises because non experts tend to put rifles on a spectrum, where on one end is the musket like firearm, in the middle are non-automatic and semi-automatic rifles, and at the far end is a fully automatic rifle such as the MG34, one of the earlier fully automatic war machines that could fire over a thousand bullets a minute. Clearly, the rifles on that high-yield end of the spectrum are best for a mass murder, right?

No, actually. Fully automatic fire is not for killing. It is for suppressing. Consider this scenario. Eight or so soldiers are advancing into a village they intend to occupy. A couple of them are carrying radios, or are medics, or in charge, or whatever. Most of them are carrying fully automatic rifles but set on semi-automatic, so they will be shooting one bullet at time. Two of them are carrying the same rifle, but set on full auto.

They are all hiding behind trees and rocks. The enemy is in sight, so if they advance, they will be shot at. So one of the full auto soldiers pulls out from cover an fires a burst of automatic fire in the general direction of the enemy, and ducks back down, while the other full auto soldier then does the same. They take turns doing this, and the enemy keeps their heads down because they are being suppressed. And maybe repressed too, depending.

Meanwhile, while these two are blasting thin air with lead, the other soldiers with the semi-auto settings turned on, don’t fire their rifles, but they run ahead to a better, closer location with a view of the enemy. The enemy did not see this because they were busy ducking. Then, a bit later, the semi-auto soldiers start picking off the enemy, one carefully fired bullet at a time.

The enemy backs off a ways, maybe one or more are wounded or killed, by they are hit by the soldiers firing one bullet at a time, and NOT by the “bam bam bam” fully automatic soldier.

So, when gun nuts* try to tell you that everything is OK because automatic weapons are not legal, only semi-automatic, you may want to tell them that you already know that the ideal killing machine in a school classroom, temple, grocery store, or nightclub is a semi-automatic assault style rifle, not an automatic weapon, and if you are using an automatic rifle, better set it on semi-auto mode to maximize the number of people you are going to tear apart with bullets.

*I chose the term “gun nut” to single out people who are not merely pro-gun, but rabidly so. Pro-gun people are not necessarily anti-gun regulation.
