Diary


I finished writing my diary last night. By which I mean it's filled, one end to the other.

I've been writing in it since Pi Day, 2002. I was seven at the time; now I'm 22. That's a full 65% of my life with this as my diary. During most of that time I wrote inconstantly and erratically, but it was always a thing I had around. Finishing it feels...weird.

Another journal was purchased long ago, so I won't be stopping entirely. In recent years I've also used various social media platforms and blogging sites to record my life, including this one. Nevertheless, I've found that private writing is more conducive to introspection than anything else, so for the time being that's not going anywhere.

MidAmeriCon Notes, Day 5

Please understand that my memory is not perfect, and that my summaries may misstate or misconstrue the views of the speakers. These should also not be taken as complete synopses of the talks given. I take notes mainly for my own use, and what is included reflects this fact. You can find a full listing of programming here.

Day OneDay TwoDay Three, Day Four.

My final day of the World Science Fiction Convention started out with a panel on worlds with Two Suns in the Sky. This was a discussion of a few hypothetical concepts and largely-unvalidated models that are nonetheless the best we can do. These include Niven's notion of a planet with an off-center core, and planets which orbit in a Figure-8.

Trying to determine the properties of a planet about another star is difficult. We can obtain the mass and approximate density from orbital characteristics, but finding chemical composition requires huge telescopes to do spectroscope. A related instrument limitation is that the Kepler Space Telescope can only find about 3% of possible exoplanets around target stars, as the ecliptic must pass between their star and our own.

For a close binary pair, it's estimated that two stars about 80% of Sol are the most likely to produce a habitable planet. Binary systems are much more likely to eject planets than single star systems. (About 30% of star systems are binary.) The minimum stable orbit radius is about 2-4 times that of the stars. It's not necessary for the planet to have formed there.

Is Asteroid Mining Feasible? The next panel set out to answer that question. The first question is which asteroids you're trying to mine. Near-Earth Objects are much easier to reach than the Asteroid Belt. The next question is what you want to mine. Are you searching for water or rare minerals. For the latter, it may just be cheaper to mine them on Earth until an adequate industrial base is built up in space. Note, too, that asteroids are not subject to many of the geophysical and geochemical processes which produce terrestrial ore deposits.

Water and other volatiles would be valuable as chemical propellants. Refueling satellites would be an obvious near-future application, but there's a sort of chicken and egg problem. Until the technology is developed, no one will build satellites with refueling capability. But the technology won't likely be developed until there's a market. Many companies don't appear to be grappling with this economic problem. A business plan emphasizing spin-off applications is desirable as it aids profitability and reduces the capital investment.

There's also legal implications. The Outer Space Treaty is quite vague about the use of off-world resources. It probably won't get resolved until prosecutions begin. Another interesting fact is that, according to one panelists, Americans and Australians are the primary supporters of space mining. Those from other nationalities are often opposed (though Luxembourg is investing in such technologies). Canada may tag along, but this seems to be mostly an Anglospheric obsession.


A higher-level concern is that asteroidial resources contribute to our current linear, one-pass economy, reducing pressure to develop more sustainable infrastructure. However, in space the perspective is different. Dragging materiel up from the gravity well is both expensive and requires considerably more structural strength than machines manufactured on orbit would.

More futuristic questions were considered by Jordin Kare's talk on SailBeam and the Bussard Buzz Bomb, two hypothetical technologies for reaching the stars within a human lifespan. His goal is a 50-year time horizon, which requires reaching speeds of at least 0.1c. Nuclear fission propulsion doesn't get us a tenth of the way there, even with staging. Fusion would be slightly better, but we still don't have that technology and only marginally improves the situation.

Using external energy gets us around the rocket equation, but most approaches to this don't allow us to slow down at the other side. Flying through an alien star-system at cruising velocity isn't really worth it, and this is the key limitation of the standard laser-driven sailship. Additionally, Robert Forward's original design had to be over a kilometer across, with a laser a thousand times that size. Dividing it into many smaller sails reduces the laser requirements but also the payload, down to a few milligrams. Considering any data sent back would need to be transmitted by laser, there's really not a whole lot there.

SailBeam is a way around this, by using multiple one-meter sails launched in succession, transferring momentum to one-another. One major aspect of this is that it requires a different material. The enormous heat flux of the laser blast, combined with tremendous accelerations, rules out metals. Dr. Kare proposes using a dielectric material, which will either reflect or retransmit most of the energy without absorbing. By his calculations this design would allow a sufficiently large laser to accelerate the sailship from zero to lightspeed in a few seconds (ignoring relativity).

There's still a lot of engineering problems to work out, of course. Guidance is one--trying to rendezvous one-meter objects across light-weeks of space would be a real challenge. Control is another--spin stabilization would require about 600,000 rotations per minute. Laser guidance, exploiting high-velocity dust impacts, and shedding small amounts of mass are possibilities to pursue.

Finally, the sail-probe would use a magnetic sail to slow down, dragging against the interstellar medium. This uses a similar technology to another proposed starship design, the Bussard Ramjet. Unfortunately, we now know that the interstellar medium is too thin for the Bussard Ramjet to produce adequate thrust. The magnetic fuel scoop would end up producing more drag than the engine thrust, just like the SailBeam. However, it's possible to seed the route leading out of the solar system with pellets of fusion fuel. Guiding these into the combustion chamber would need a much smaller scoop, which could be repurposed as a small shield once reaching cruising velocity. A "runway" a few light-days long would be adequate, which the ship would cover in a few weeks time. By the end, it would be experiencing about 30 fusion explosions per second.

The next panel I went to was about Human Culture in Remote Space Settlements, which by and large didn't really address the question. For me, it raised another: what makes a panel work? Does it depend on the moderator? A coherent question? Relationships between the panelists? We don't know.

I did take away a few good points, however. One is that many of the worlds around nearby stars are likely to be tidally locked, which poses a challenge to colonization. It's quite possible that fixating on planets is the wrong approach, when we could much more easily build nice, comfortable space colonies from the resources of the system. This solves the problem addressed in the generation ship panel on Friday, asking why colonists would bother getting off the ship.

Another thing discussed was the notion of athletics in space colonies. There would be the normal sports we know, combined with low-gravity and zero-gravity activities that are yet to be invented. Depending on the size of the habitat, some of them may need to be adapted to account for Coriolis forces. Physics class will be very different in an O'Neill Cylinder or Stanford Torus.

The afternoon's main attraction was a chat between George R. R. Martin, Pat Cadigan, and Michael Swanwick reminiscing about the first MidAmeriCon in 1976. I jotted down a few things, but won't try to condense them into something coherent.
The final event I went to was dialog on asking Can Hard Science Fiction be too Hard? The answer is: it depends on your readers. Different people have different preferences and levels of scientific literacy--whose your target audience?

Appreciate the limits of infodumps, and ask if you should explain your work in the text. There's a sort of taboo against putting equations in your books, but some readers really like that sort of thing. Part of the problem is dislodging popular misconceptions before inserting the truth of the matter.

Science fiction shouldn't really be hard for hardness' sake. Real-world difficulties should cause difficulties for your characters. A common example is the lightspeed delay. Just because a story is set in space and deals with that doesn't mean it has to be a Mohs 11.

Many readers will forgive small errors if you get the big stuff right. Asimov said that there's a relativity of wrong, and he was right. Our modern models are true in broad strokes, but many of the details may change as the scientific method continues its process of refining and revising. If you reach the limits and veer into speculation, be honest about it. Speculative physics, biology, or psychology can still make for a great story.




That's the final report. WorldCon was a great experience, but it was also a lot of work. I'm almost relieved to be back at engineering school.

MidAmeriCon Notes, Day 4

Please understand that my memory is not perfect, and that my summaries may misstate or misconstrue the views of the speakers. These should also not be taken as complete synopses of the talks given. I take notes mainly for my own use, and what is included reflects this fact. You can find a full listing of programming here.

Day OneDay Two, Day Three.

I arrived a bit late this morning so only heard part of the talk on Alienation in Science Fiction. A big part of this panel dealt with the question of whether science fiction is still an "outside" genre, and what either answer would mean. Many expressed a concern about the difference between Geek Culture and Nerd Culture (geeks go to Comic-Con, nerds go to WorldCon). Many 'pop' sf shows are more cosplaying science fiction than engaging with the underlying questions that made the genre interesting. Consider The Big Bang Theory.

Others argue that geekdom and nerddom are overlapping categories, and that one can move between them. Even if many new sf fans aren't interested in the serious stuff now, it doesn't mean they won't later.

Part of what science fiction unique was it's willingness to ask questions. In a culture where everyone asks questions, that's not very special. Is that evidence that scifi has done it's job? One panelists argues that science fiction as a genre is over, and we need to look to the future for real now.

For those of us still deadset on writing there was The Art of Worldbuilding. Edgar Rice Burroughs invented much of the modern art--flushing out all the details of a fictional world. Barsoom is the obvious example. It's not perfect, but he covered a great swath of space in loving detail.

There's different places to start. You can ask why your world is interesting. What are the implications of any given premise? Do you have characters with professions? Images in your mind? A tone you wish to establish? Values systems to explore--what do this world's inhabitants love and fear? How does that impact their economy and political system? What are the story's thematic drivers?

Readers don't need to know all the details the author knows about the world. Sometimes you'll have blindspots. Getting a beta reader to ask questions about it. You might not know something important. All information needs to have a purpose.

Overresearching is a problem which strikes many writers. "Prepcrastination" is real, and can be combated with time limits. Many authors just note what needs to be filled in, and wait until the plot is rolling to add the details. Some iterate on the world between drafts. 

Don't frontload the exposition. Readers will accept more once they're invested in the story and plot.
The lighting wasn't that great for photography in there.

The next talk I attended was on SF Pulp Art, which was interesting but not conducive to paragraph summary. I'd recommend getting a good history of science fiction book and reading that instead.

Jesper Stage of LuleĆ„ University of Technology gave a presentation on Interstellar Trade for Fun and Profit, looking at both technological and economic perspectives.

Shoddy worldbuilding is often given away by economically infeasible situations. Resources need to come from somewhere, and trade routes require multiple hubs. A spaceport is useless if you can't go anywhere.

Consumer price is equivalent to production plus transport costs. The latter are huge for interstellar exchanges. The value of a physical product either needs to be huge, or you need really cheap starships. If the former, there needs to be a reason why you can't produce the product at home.

Alien ideas and media are an obvious IP trade good. This applies with humans as well.

Cheap FTL changes things, in ways you might not expect. In that case, we're competing with aliens adding political incentives, such as controlling trade routes and losing economic autonomy. A multi-star civilization might experiences "cosmization".

Far future fiction is much more optimistic about trade compared to near future fiction. Economists and enlightenment philosophers agree that trade is a net-benefit and makes people better through incentivizing upright behavior. Many fiction writers echo this notion, either because it's a fun plot device, or because it's easier to see the big picture in a galactic scenario.

Alienbuilding dealt with the question of interstellar interactions for a biological and psychological perspective. Some writers start top-down (star, planet, biome, evolution, aliens), while others start with an alien they like and work the other way. Larry Niven advises us to ask "what's the weirdest thing about them?" This can guide your design. Note that easy description is good for booksales.

Don't overdo the alienness, because eventually it becomes impossible to write a story about them. On the other hand, don't make them humans that look funny. This is especially true if you base their culture on another human society. It's tacky and limits your international market prospects.

An important question in the field is the relevance of toolmaking to intelligence. Humans suit our environment to ourselves. Aliens may suit themselves to their environment. It's a good idea to research the incredible morphological diversity of terrestrial life to get an idea how big the space of possibilities actually are.

Strange starting points limit your ability to extrapolate. Many biologically interesting premises don't lend themselves to fun stories. A few things that do warrant more speculation include non-animal intelligence and the variations within species.

I was afraid the panel on Political Worldbuilding would be ideologically triggering. In fact, it was boring as hell. The scientists are spoiling me. A few things to consider are the notion of political systems as technology and the symbolism fictional systems will have. To gain perspective, consider reading about how other cultures conceived of past societies. Modern political shapes probably aren't the default. Again, work out more detail than the story demands.


>>Self Referential Caption<<
By this point I was feeling a bit worn out, so went to see something funny. Fizz and Fuse, the Reactor Brothers is an audience participation skit done in the style of car talk. Listeners "call in" with various sci-fi inspired spaceship problems, and they try to come up with plausible sounding advice. I didn't write much down, but there were a lot of puns and nerdy jokes. For example:
Finally, I sat in on a panel discussing the latest progress in Exploring the Solar System, and what's coming next. Nominally this was about planetary science, but the audience seemed more interested in launch technology once Q&A rolled around. I elected to leave a few minutes early.

One big take away is that space is hard. We're still getting the hang of chemical propellants. Advanced propulsion holds promise, but a lot of work is yet to be done. What a spacecraft is designed to do is not necessarily what it was built to do. Sometimes mission controllers can do things outside the specifications with ease. Sometimes it falls apart.

More and more we're worried about contaminating life-carrying environments. Personally I'm skeptical about widespread abiogenesis and panspermia, but it's still a matter to be cautious about. There's a lot of interesting places to go in the outer solar system. The trans-Saturnian parts are still very neglected. We don't understand Pluto's energy budget, and JPL is try to set up a solar sail fleet to explore heliopause.

For that matter, there's a lot about Earth we still don't understand, geology particularly. How is our magnetic field generated? Fast rotation seems to be a requirement, but we just don't know. Investigating the other planets' magnetospheres can help us in this quest.

That's about it for Day Four. We didn't stay for the Hugo Awards for the same reason we didn't vote: you really should be informed, and I haven't read any new fiction.

MidAmeriCon Notes, Day 3

Please understand that my memory is not perfect, and that my summaries may misstate or misconstrue the views of the speakers. These should also not be taken as complete synopses of the talks given. I take notes mainly for my own use, and what is included reflects this fact. You can find a full listing of programming here.

Day One, Day Two.

The day started out with a presentation on Solar Sails, given by an engineer who researches them for NASA. The basic theory is that space is largely not empty--there are in fact radiations and electromagnetic fields which sufficiently light spacecraft can exploit for propulsion. His talk was largely technical, discussing the history of solar sail experiments and upcoming missions, including NASA's Near Earth Asteroid Scout, which expects to launch with the SLS on Exploration Mission 1.

Les Johnson during his presentation on Solar Sails
Next I enjoy a panel on Defining Acceptable Risks in Space Exploration. In then end, the was not defining answer beyond that that must be decided by those planning to go and those footing the bill. The risks include radiation, where long-term low dosage exposure is still understudied. Patients undergoing cancer treatment are one of the few groups being studied. Putting mice in linear accelerators is about the only way to simulate the cosmic background. Jerry Pournelle reiterated several times that he believes a moonbase to study the effects of long-term stays in deep space is essential. Microgravity is another concern. It's unclear is Martian gravity is sufficient--Luna's certainly is not. Again, there's no way to know but find out.

Technical problems abound. A little shielding is worse than none because of secondary radiations. Building a rotating habitat to simulate gravity has its own issues--being large enough to avoid head-foot differentials and dizzying Coriolis Effects requires a tremendous size. To build it with adequate shielding stretches our propulsion and material sciences capabilities.

Drugs to treat altitude sickness may prove good at combating inter-cranial swelling. Similarly, drugs may be the best solution to other issues such as bone and muscle deterioration. In the end, more research is needed.

The Future is a Different Country

"I can give you disinformation from lots of perspectives" --Edward M. Lerner

What sort of technologies will have the biggest impact for scifi writers to consider in the coming decades? Lerner believes malware is going to be a lot peskier as the Internet of Things continues, and that carbon-based computing will drastically lower the cost of putting computers in things. Patrick Nielsen Hayden notes that ebooks haven't decimated print books, but that mass-market paperbacks were in fact the product of development in printing technologies.

It's easy to predict first order effects. Second and third order effects are very difficult. The example is predicting automobiles versus predicting traffic jams. It's not impossible, but it's hard to get it right. Many possible futures exists.

What effects will automation have on industries? Will basic income solve the unemployment crisis? Many expect a post-scarcity society will become an enormous status-competition, though subcultures may mitigate this. Virtual communities allow a lot more outlets for obtaining status.

AI and fusion are both largely overhyped, and it's hard to say when if ever they'll mature. Extrapolating from past trends is challenging. How virtual reality fits into the picture is interesting. Panelists agreed that it won't become universal until it's truly immerse for the same reason the Wii has a limited market: you'll step on the cat or break the TV screen.

Back to things more objective: Explore Mars, given by an engineer who worked on Sojourner and the Mars Exploration Rovers. This talk focused largely on the geological discoveries and ground covered by the rovers as they far exceeded the mission designers wildest dreams. We've gotten really lucky with where the last few probes have landed. We'll see if the next several missions have the same good fortune.

Next was writing advice, specifically Raising the Stakes in Middle Grade Fiction. Historically, MG fiction has been episodic, essentially short stories with the same characters. Overarching plot is a newer feature.

One way is to simply make things more serious and let the editors reign you in. Frequently it's just changes in wording that are necessary, while the implications remain clear for the author actually writing the story. Note that writing as if your characters aren't safe (even if they will be) can make it seem much more serious without exceeding the MG boundaries.

Keep the protagonists appropriate for their age level. Kids make mistakes adults wouldn't. Keep in mind what will make the story exciting in the next scene. The story is over once the problem is solved (which raises challenges for series authors). Don't be afraid of experiments. Characters often end up diverging from the outlines because human behaviors are more realistic when the story is unfolding than when it's unfolding in an outline.

The emotional response should work on you. If it doesn't, it probably won't work on readers, either. Many YA authors over-parent their characters. They're not X year olds, they're real people with X years of experience. Kids need to participate if you're going to market it towards kids. That also means no sex scenes, and avoiding permanent injuries and traumas.

Public spaces are a goldmine for good dialog.

Next was a less exciting panel on Space and Human Speciation. The first question we need to ask is what defines a species. Is it interbreeding capability? Morphology? Human populations have been separated for millennia can still interbreed. It would take a very small sample to have sufficient genetic drift less selection pressures to speciate away from homo sapiens.

Adaptation for microgravity and radiation are obvious things which we might genetically engineer for. There's also microbiome effects, and the tribal aspects of interbreeding. Generally, we expect "attractiveness" to matter far more in larger groups than smaller. Epigenetics may also play a role.

Dwarf Planets and Beyond the Kuiper Belt was quite interesting. The IAU definition is not necessarily clear, but that doesn't really matter. The Outer Solar System is far more interesting than we expected because ices are far more malleable than rock, meaning less energy is needed for geological activity. Pluto has water icebergs in oceans of solid nitrogen. It's fascinating.

Ceres is also active, still in the process of mantle differentiation. Lots of water should be available near the surface, which combined with the low escape velocity (about 500 m/s) means it could be a valuable waystation in the asteroid belt.

Lots of dwarf planets have large moons, which suggests frequent gentle collisions. Consider the example of comet 67P Churyumov-Gerasimenko, which appears to be the combination of two nodules.

Currently about $30 billion is spent on space globally each year. That number will go up as developing nations grow wealthier. There's lots of exciting missions and the technology to attempt them. Graphene solar collectors could work as far out as the Kuiper Belt, opening much larger swaths of easy territory. The next few decades are about exploration and tech development. Accessibility is still governed by delta V. Humans will go, but even more robots will go with them.

Also, it's possible the evidence supporting Planet 9 could also have been caused by a solar encounter.

Finally, I went to a talk on Generation Starships. These are a staple in science fiction, but present a lot of serious issues. Firstly is the question of generation ships versus cold sleep. It may be possible to use both, which would be useful, as the cultural elements necessary to keep the ship running for centuries would not be well-suited to colonizing an alien world. Many are worried about such ships suffering their own version of the Easter Island problem.

Autonomous space colonies would face many of the same problems. I think this is a good thing--it lets us test the problem before sending people way beyond help's reach. We've already experienced certain aspects on Earth, but ultimately a generation ship is unprecedented in human history. What we have seen isn't inspiring. Many are affected by large environment changes. Pioneers have often discovered their social values just don't stick in a new world. Ensuring a sense of responsibility and ensuring there's enough recreational options to stay sane is a definite challenge.

One possibility is engineering non-fatal catastrophes to occur each generation, to keep people on their toes. Pournelle gives the example of military bureaucratization: nearly half a century since the last serious, life-threatening war has made things inefficient. It may be necessary to make the exploration of new worlds a religious ideology. Ensuring everyone gets off at the end isn't necessary--the people who remain can refuel and head off for the next star.

That's it for day three. Check back again tomorrow for the next update.

MidAmeriCon Notes, Day 2

Please understand that my memory is not perfect, and that my summaries may misstate or misconstrue the views of the speakers. These should also not be taken as complete synopses of the talks given. I take notes mainly for my own use, and what is included reflects this fact. You can find a full listing of programming here.

Day One.

The first talk I attended was When Robots Rule the Earth by Robin Hanson. Essentially, he hit the major points behind his book Age of Em. I could do an entire post on that talk alone, but let me discuss a few of them.

First is the rate of economic growth. On a logarithmic scale, human history can be described by punctuated equilibrium of productivity--a series of plateaus, with sharp jumps in between them. The duration of these plateaus is also a trend, which is where he gets the 1-2 year estimate for how long the next period will last.

Hanson is describing one possible scenario with his notion of brain emulation. Many others are possible. He estimates that the age of em has greater than 1% chance of being what happens.

Without having read the book, I don't know what he covers and what is novel to readers. A few things stuck out to me, though. One was the notion that as our wealth increases, our lifestyle becomes more like that of hunter-gatherer societies (high recreation, more flexibility, etc). Emulation society, since it would likely be hypercompetitive, might end up more like the farmer-herder cultures in terms of restricting values. A consequence of this would be higher religiosity in ems than humans.

Additionally, em society would be more stratified than ours, though likely by simulation speed as opposed to productivity (Hanson hypothesizes that only the very best humans would be emulated). Simulation speed would impose a constraint on communication distance. Human brains run far slower than the theoretical limit for transmissions around the world. Minds running thousands of times faster would not have that luxury. Note that ems would not be interested in space travel for this reason (and because their entire era might end by the time a Mars mission could be completed).


Dr. Hanson during his talk.

After that I went in for something a little lighter: New Trends in Young Adult Novels. The resounding conclusion from the panelists was that trying to follow trends is probably not the best idea, because the time between beginning and publishing a book is too long (which is why we see so much trash after a good series kicks off a fad). A better approach is to write drafts and dust them off when a new trend begins.

In the longer term, young adult books have mostly been written in first person, and increasingly the present tense. Middle grade books are still frequently in third person, and more likely to be past tense. First person aids in immersion, but isn't a strict requirement.

That said, a few things are known. Romance is overdone. Dystopia is going out, if you've written one try branding it as science fiction. Horror is in right now. Multicultural stories are finally getting the sort of attention they deserve.

Oh, and reviews matter more than most readers think.

Science Fiction as Epic was largely forgettable, though the concert on the other side of the wall didn't help any. I don't feel like I learned very much from this one. Epics can be considered to run to things out to the very edge of their world, with larger-than-life characters and a large canvas. In science fiction this is often embodied by the genius scientist or daring astronaut types. Humor is a dangerous element, as it can undercut the melodrama. Economic considerations are rarely looked at. Does an epic require adventure? We don't get a definitive answer.

The next talk asked whether Heinlein Juveniles Stand Up. I'm pretty sure I was the youngest person in the room for that, but the panelists report that by-and-large they do, though perhaps not for the reasons one'd expect. It isn't unrealistic spaceships that throw off contemporary readers--it's the slang. That never bothered me, because what modern slang I picked up left a bad taste in my mouth, but am I a typical youth? Hardly.

Part of Heinlein's appeal is his refusal to talk down to young readers. He saturates his stories with technical details and moral messages, because they're sincere and practical. A big part of his juveniles deal with the training of the protagonists, usually not in traditional schools. The actual plot is frequently formulaic (or is that just hindsight bias?).

Several commentators said that they feels his juveniles read like the first half of his later works, which feature a lot more introspection about the world characters find themselves in.

Heinlein juveniles usually feature competent mentor figures, teaching the protagonists about citizenship, responsibility, and ethics. His characters are not "the chosen one". They either earn their place, or are randomly entrapped in their adventures.

He frequently focused on male readers, possibly because the science fiction fan gender balance was worse back then, and also because that what the marketers thought would sell. His long-running adversarial relationship with the editor was largely over what he wanted to write, versus what would actually get bought and put in libraries. After Starship Troopers was rejected, he gave up on writing books for kids.

Some of these books are currently being adapted to graphic novel form by the estate.

100 Years of Continental Drift was a big heavier. I learned that the first recognition of similar coastlines was in the 1600s, but no progress was made before Wegener formulated continental drift. His theory was rejected for multiple reasons. One was outsider bias: he was a German climatologist trying to tell American geologists how to do their jobs. Another was that his mechanism proved factually wrong. Continents don't cut through oceanic crust, driven by Earth's rotation--continents would accumulate on the equator, and basaltic crust is far more dense than the granite of land. Think of butter cutting a knife.

Plate tectonics proposes a more plausible mechanism--convention currents in the mantle--and benefits from more modern evidence. After World War II a scientist used Navy data to argue a ridge existed in the Mid-Atlantic. Her absurd claims were proven wrong when they sent down a submarine and there the ridge was. More interestingly, there's symmetric signatures of Earth's magnetic reversals in the rock on each side of the mountains, suggesting sea-floor spreading.

Another interesting piece of trivia is that Olympus Mons is so big because Mars didn't have enough heat to drive plates around. Olympus Mons formed from a mantle plume, but never moved. Imagine how big Mauna Loa would be if all the Hawaiian Islands were pooled into that one mountain. Internal planet heat is ruled by an inverse square law.

Earth is expanding by about 0.0001% per year, but that's far to low to justify claims of Earth Expansion Theory, which is popular among certain Creationist sorts.

Something I probably once knew but forgot: most of our knowledge of Earth's interior comes from nuclear tests, which produce large vibrations which can be detected on the other side of the planet.

Dad went to the talk on Heinlein Predictions, and I took notes for him on Middle Grade versus Young Adult Fiction. The answer is that it's largely subjective. Keep in mind that kids usually read up--just because your protagonist is 15 doesn't mean your target audience is.

They might also be older, since adults with disposable income read a lot of YA. For one thing, YA is easy reading for fully-formed minds. Another reason is because it deals with early life experiences, which are much more intense the first time around. A good book can evoke a lot of emotion in adults thrice the target audience's age.

Getting into the content distinctions, MG deals with a lot of kids with power in their world. Think "adventure with fun and friends". YA deals with the reality of continued helplessness and the problems that teenagers experience: school, relationships, and life choices.

The panelists emphasized that children today live very different lives than the adult authors writing for them. They know a lot more than you think they know, but are also held inside by the modern scaremongering. Books are their playground. This can be both good and bad. Books let them into worlds they couldn't experience themselves, but can also warps their perception of normal. YA relationships are generally not healthy, and when read by impressionable readers.....

On a technical note, length isn't a huge factor in the post-Harry Potter era. Don't write War and Peace unless you have a trilogy deal, but don't worry about 100,000 words.

The final talk we attended before heading home was on Creating Worlds in Fantasy, Science Fiction, and Horror. There's different approaches to this. Do you build the world first and then insert the story? Do you begin with a character and then construct the world around them? You may not have the time or desire to figure out all the details. This isn't a bad thing. Mystery is often more satisfying than half-assed answers (for instance, midi-chlorians).

Handwaving applies to societies just as much as technology. If the story is good enough, it won't particularly matter. Alien worlds may require a ton of research to make plausible. If you're relying on adjectives to get the emotional response you want, you've failed at your job.

Character-driven fantasy is hard--many choose to focus on the relation between the character and their world.

Pay attention to your own rules. Understand the world you're writing. Many stories that used to work don't work anymore because everyone has cell phones. Deal with consequences realistically. This especially shows up with major character deaths. Don't make your characters invincible and certain of victory if you want your reader to be engaged. There has to be an emotional stake, but it's too easy to introduce characters just to kill them off. Family costs are overdone.

Timing is important in exposition. So is relevance. You don't need to frontload the exposition, but also don't interrupt action scenes to give us details. Infodumping and character interaction are okay. Don't feel the need to do everything in dialog--it leads to unnatural conversations. Reading aloud can help.

For another Star Wars example, prequels usually fail because the relevant information has already been delivered. Discerning viewers can pick up all the major events from dialog in the original trilogy.

That's it for day two. I would have liked to have stayed for the panel on locked planets, but it was late in the evening and I need to turn in.

MidAmeriCon Notes, Day 1

Please understand that my memory is not perfect, and that my summaries may misstate or misconstrue the views of the speakers. These should also not be taken as complete synopses of the talks given. I take notes mainly for my own use, and what is included reflects this fact. You can find a full listing of programming here.

The first panel I attended was on Kansas City's Favorite Son: Robert A. Heinlein, featuring Dr. Bradford Lyau and Jo Walton. As a native of the KC area, Heinlein was a guest of honor at the first MidAmeriCon forty years ago. Midwest upbringing undoubtedly influenced his writing. The other two members of the Big Three were from New York (Asimov) and Europe (Clarke), and each represented a different sort of mindset.

A great deal of Heinlein's work deals with a dynamic between a romanticization of his Midwest upbringing, and his desire to escape the false assumptions that pervaded it.  For example, he claims he lost any lingering religion after reading Charles Darwin (he was raised in the Methodist Episcopal Church, an abolishionist offshoot that split before the Civil War). There was both a desire for sophistication, and a feeling of pride for the place he came from.

One consequence of this upbringing was valuing honor and nobility, in a way that many of us today don't entirely comprehend. Heinlein cared about conduct. Walton argues that part of his rhetorical skill comes from appealing to the reader's desire for self-excellence, to be one of the elite. Much of his contribution to science fiction as a movement comes from trying to make writers and fans see their role in history, and act accordingly.

Two of his lifelong influences were Mark Twain and H.G. Wells, who contrasted country cynicism with a utopian optimism about the future. One peculiar instance of the latter was his belief that he'd outlive communism. He nearly made it--the Berlin Wall fell less than two years after his death in 1988.

After that came Earth, We're Stuck Here! This panel explored the challenges of deep space exploration and trying to live on other planets. There was a lot of tension between panelists on the role the government had to play--some argued that it was nothing but a hindrance, others believed NASA is doing the best they can given the challenges. One of the major issues is radiation dosage. We're safe under Earth's atmosphere and magnetic field, but in interplanetary space astronauts will be exposed to both higher cosmic background and occasional solar flares. It's currently estimated that a year in LEO adds 3% lifetime cancer risk (with a base rate around 15%). A 1000 day mission in deep space is estimated at 1 Sievert radiation dose, compared to 150 milliSeiverts for a year on the ISS. So a standard mission to Mars is approximately twice as much radiation as the equivalent time on the space station.

Reduced launch costs could help, though I think a 100x reduction by 2030 is a bit too optimistic. One aspect is marginal cost--a good chunk of the shuttle's enormous pricetag was overhead. Adding another mission to the schedule didn't cost a full $1.5 billion. This means that a successful strategy for reducing launch costs may be cultivating high-volume markets. Unfortunately, there aren't a whole lot of new missions in the pipeline, in no small part because NASA is always in a precarious funding situation. Solving that would go a long way toward making the Space Launch System a winning proposition.

Moreover, we don't really know how to operate above LEO. Again, making space access cheaper would do a lot of allow for more experimental missions, but that's a long way out. We may want to take a more cautious approach--going back to Luna, establishing a base, and so on. Understanding the role of microgravity is important. How much is enough? It looks like any is better than none, but is 1/3 adequate? 1/4? 1/6?

My next panel was back to the fiction world, where the biggest conflict was whether War and Peace is a good book. It was on writing, specifically, Writing Major Minor Characters. This is the art of getting the most out of small details--getting enough characterization without going through the whole process of "rounding out" a character. One panelist mentioned that giving a single detail not relevant to the plot is all it takes in short stories (more is necessary in novels, if that's what you're trying to accomplish).

It's important to realize that is minor characters don't contribute to the plot, then you should be asking yourself why they're there at all. The amount of attention and space given to a character should be proportional to their contribution. Does a given scene advance the story? Does a particular person need details given? According to the panelists, a significant skill for writers is realizing when you've written unnecessary material that needs to be taken out.

Sometimes that material can be reworked or added into later drafts. One valuable tactic is uniting throwaway characters into a single, significant castmember. Other times you'll end up with a major character in disguise--someone who doesn't seem important for most of the book but ends up mattering at the climax.

Realize that realistic characters don't need to be well-developed. Connie Willis told a story about a stereotypically slow and annoying person in front of her at the pharmacy. We've all encountered such people, and hated in them for that moment, even though they probably have a long story and rich inner life. The same is true for minor characters. We can recognize such characters, and our minds fill in the rest. Writers can easily let their readers fill in the details so long as they've been pointed in the right direction.

The Opening Ceremonies where a bit underwhelming. It felt a bit disorganized to me, and the audio hookup wasn't that great. I probably should have gone to a talk instead.

The final event of my evening was 1950s Science Fiction Movies, discussing the great and terrible films made in that era. I didn't take very many notes because the lights were off most of the time so we could see the host's slideshow, a couple points stood out. First was the different gender dynamics in various movies. Some still look egalitarian today, while others were already starting to look backwards then. Particularly focus on the conduct of scientists in such films, and importance of script/dialog in an era when special effects couldn't carry a film.

Viewing recommendations include Them!, The 27th Day, and the European cut of First Spaceship on Venus.

The past and future of transportation, side by side.
That's it for day one. Check back tomorrow for the next round of updates!

Links for August

UFOlogy gets serious.

Virginia Postrel argues that donating used eyeglasses is extremely ineffective. Nice to see more effective charity discussion among libertarian types. Speaking of, Libertarian Party nominee Gary Johnson isn't ruling out basic income. Reminder that GiveDirectly is testing guaranteed basic income in Kenya.

Ned Resnikoff argues against sentimental democracy. Also see this article on the failure of redemptive constitutionalism in The Atlantic.

An interesting hypothesis of governance from Peter Thiel.

Marginal Revolution on the rapid loss of ideological diversity among university faculty. Maybe the Koch brothers recent decision to drop national politics for campus/thinktank activism will mitigage this trend.

KIC 8462852  is still doing weird shit.

Finally, I'll be attending the World Science Fiction Convention for the next few days. I'll be posting throughout the day on Twitter and writing up summaries here each night. If I get inspired, maybe I'll resurrect my writing blog in the fall semester.

Willpower Sinks

In May I mentioned "general willpower sinks", which I've been meaning to talk about since I noticed the phenomena this spring. That never materialized, because I'm bad at working on projects that aren't right in front of me. Maybe I should draft my blogposts in txt files on my desktop.

Anyway, the alternative is cleaning my room, so let's talk about them now.

What I mean by this term are things which require significant willpower to accomplish during the course of the day, yet which do not contribute in any way toward my goals. These things need to be done, but only in a jumping-through-hoops sort of way. The most obvious example I can give you is climbing up the hill to go to class, because somebody thought putting a university on top of a small mountain and the housing at the foot was a sensible and intelligent plan.

Getting to class facilitates my success. Climbing up a hill does not. Insofar as I have to put up with it, it's a willpower sink. I dump willpower into it, and don't really get anything back out.

Maybe it's just my perennial cynicism, but adult life looks increasingly like a collection of willpower sinks which could be avoided if people just agreed to do away with them. Climbing the hill seems this way, to an extent. We could level Mount Oread and rebuild KU at a more sensible elevation, but that's unfeasible for multiple reasons. Only a few of them are very good.

Someone (probably my mother) is going to tell me that doing things we don't like is just a part of life. That's my whole point here! We have to do tons of things we don't enjoy to achieve our desires. My response to this reality is to not waste willpower on unnecessary things, because willpower is scarce and human happiness is scarcer.

The best argument I can generate in the defense of willpower sinks is that they help build discipline in the face of adversity. In an idealized case, that would be valid. In the real world, I'm 22 and literally complaining about walking uphill (both ways!) to school. Character-building experiences are not evenly distributed, and I can only see this problem getting worse as the 21st Century continues.

For the solution, I invoke Weird Sun Twitter:

Picoprocrastination

In my post on hyperbolic discounting in May, I wrote about the akratic habits of university students and the consequences these bring. Specifically:
Compare [the quoted Less Wrong post] to a college student's tendency to procrastinate, rush assignments, not study, and consequently get lower grades than they would otherwise. I'm looking at you, 2013!Nathaniel. 
Actually, I still have this problem (though to a much lesser extent), which is why I'm writing this post when I have two final exams in the next 48 hours. While I dislike the university alarmism, the grades (and more importantly, habits) one obtains during their tertiary education has a tremendous impact on the trajectory of their life. Yet extremely little attention is given to the innate psychology of human beings which makes us act against our own long-term interests.
This doesn't actually do a good job communicating the problem I'm having. Discussing procrastination in terms of the consequences is usually a mistake. Looking at the causes is better. But I want to talk about the methods.

A problem that I've had trouble expressing to family and friends educated before the social media age is the dramatic change in how students my age procrastinate. It's not a conscious decision to not study. It's idly clicking "new tab", typing a few characters, and there you are. It's not putting on your coat and going to the bar, it's not deciding to read a book, it's not even sharpening a pencil and throwing it at the dart board. It's a near-reflexive reaction to the slightest bit of boredom or adversity.

More importantly, it's almost never something which will trigger a serious future-value calculation unless you're so conditioned. Even if it does, there's a lot of ways that can go wrong.

Social media taps right into our dopamine centers, giving us inconstant rewards for checking if there's fresh juicy posts in our newsfeeds. This can be useful, if practiced intelligently. The Pomodoro Technique is one such strategy. It can also be damaging, but that's not really the point of this post.

No, my point is that these things largely are not conscious decision on the part of interested actors, and trying to deal with them as such will be under-effective at best. If you or someone you know is struggling with picoprocrastination, you have to kick yourselves up into far mode and thing about it dispassionately. Be prepared to accept conclusions ranging from delete-twitter-right-this-instant to everything-is-okay-carry-on. This last bit is probably the most difficult, because we've usually made up our minds long before the debate begins.


This post didn't quite go as expected. At least that means more thoughts to get out later.
