Avowed Metalhead Now President of World's Largest Muslim Country

More here on Joko Widodo, president-elect of Indonesia.



Given his shirt, I wonder if he is "chuffed". Indeed, perhaps his father said, "Turn that dine. Turn that unemployment dine. Wot koinda policies are them." Napalm Death inside jokes have a limited audience, but such is my refined taste in humor.

Why Video Games Haven't Wiped Out Movies

Video games generally have a much better ROI than movies (actual figures here), to a point where you can't help but wonder why the entertainment industry is still making movies. (Status to studio executives? Status and financial incentives to irrationally optimistic individuals, i.e. actors? Difficulty of retraining talent?) But there are reasons that games haven't completely dominated the entertainment industry yet, and one of the more not-immediately-intuitive ones is that each individual product tries increasingly to keep players online for more hours. Assuming a finite number of game customers, that means that as games get better at holding onto a finite pool of player hours, newer games have to be much, much better to compete, or just be satisfied with ever-shrinking market shares. Many more observations here.

A Fun Game: Science Fiction Mars, or the Navajo Nation

One is a picture of Navajo Mountain, Arizona (presumably from Lake Powell; credit mikereyfman.com) and the other is one of my favorite cover art pieces ever. Spot the difference.

File Under F for Fermi Paradox

"Taiwanese student in heavy water over homemade fusion reactor". If technology continues to progress, one day we'll look back on fusion as being in the same category of technology as smelting bronze. How many ill-advised school projects will there be between now and then?

Take solace in the fact that this particular technology is not self-reproducing.

The Boys from Brazil? Or the Boys from Toronto?

In keeping with making bizarre connections between pop culture and academic topics, I illuminate a creeping dark conspiracy that so far as I know, only I have detected! Dear reader, lean close to your screen, for I am about to impart arcane and forbidden knowledge! If you are a fan of economists, as well as the the greatest comedy show ever Kids in the Hall (KITH) (yes, in fact it has stood up better than Python), then shame on you if this has escaped your notice!

Here's Scott Thompson about 1990:




Here's the background picture on economist Justin Wolfers's Twitter feed:



I mean come on.*


*An underappreciated fact is that this is the English translation of both QED and ipso facto.

Heavy Metal Frost on Venus


False color, real topography rendering of what
Venus "frost" might look like (NASA)

Besides being the coolest title for a paper ever, this is the explanation for the highly reflective "snow" seen on high mountains on Venus by the Magellan mission in the mid 90s. Specifically, based on spectroscopic data, the authors argue that this material is lead and bismuth sulfides precipitated from the atmosphere.

Review: Dave Mustaine and the San Diego Symphony

There are many reviews out there, and few were kind. The show was sold out for quite a while. Relative to the '99 Metallica symphony show, the crowd definitely leaned more toward regular-symphony-goer types, but that could just be because it's 15 years later and the metalati are getting old, i.e. they ARE the symphony-goers anyway. Overall I think it was better than the Metallica SF symphony show, because it was more risk-taking. In execution, maybe not so much. Most of it was just the symphony, and the parts where Dave was on stage, he was the only extra-symphonic performer, and he didn't play his own material, and he didn't dominate the sound and make the symphony superfluous like Metallica did.


Set list:
Berlioz, Roman Carnival overture

Bach, Air (with Dave)

Vivaldi, Four Seasons, Summer and Winter movements (Dave joined them for Spring, playing the first violin part)

Dvorak, New World (4 movements)

Encore:

Megadeth, Symphony of Destruction (two main riffs, played by the symphony, without Dave)

Wagner, Ride of the Valkyries


Dave was fairly humble and magnanimous. He said that it was very intimidating being in front of so many accomplished musicians, and several times the pickups on his guitar cut out (which marred the performance) but he didn't seem to get upset. He was using a guitar with a wood body that looked like a violin. There were several places where his fretwork got sloppy and honestly the Pergamum version of the Summer movement on Youtube is superior. To be honest my favorite part was Dvorak!

As with the Metallica symphony show, the regular conductor was too cool to be there. I would argue that the conductor contributes the least of anyone in a symphony, so ih.

Dvorak, New World (Second Movement)

Shreddinger's Cats

1. Metal and cats. It's the internet, I shouldn't have to tell you anything else. I mean come on.

2. Extreme metal puss #1.



3. Extreme metal puss #2.



All bow before the god-king of all metal pusses.

Massive, Old Terrestrial Planets = More Likely Life

The more surface area a terrestrial planet has, the more likely it will harbor life - because it has more reaction area and volume to do it, not to mention more gravity to pull in material (especially from organics-heavy comets). And Kepler 10c is 10 billion years old too, so it's had more time to do it. Even if the recently discovered mega-Earth Kepler 10c is a toasty 5700 Kelvin, there will be others that are not.

We should be looking at large, old terrestrial planets for evidence of life.

Trolley Problems Are Now Real Problems

Cross-posted to Cognition and Evolution.

Trolley problems are moral exercises (or experiments) where participants are asked to choose between horrible choices, to see how our moral reasoning works. For instance: do you push one person onto the tracks of an out of control trolley to keep five people further away from getting run over? Or do you just not say anything if you see a single careless person wandering into the trolley's path of his own accord, to keep those five people safe? Among other interesting observations in these experiments, we are inconsistent, and people who claim vastly differing moral foundations (religious and atheists, for example) tend to choose the same answer, as long as they're otherwise from the same cultural background (e.g., they're both American). Some enterprises already exist attempting to "solve" morality, that is to be able to program it into a computer, partly motivated by a belief in the impending technological singularity.

Trolley problems are criticized as being able to give us a window into actual moral reasoning for some of the same reasons same reasons as any consequence-less self-report method. But literal trolley problems are now becoming consequential, now that we have driverless cars. Their engineers have to encode how these cars will decide who to hit, if they find themselves in a situation where they have to hit someone. If they have a choice between a helmeted and non-helmeted cyclist, shouldn't they aim for the helmeted cyclist to minimize harm?

If only things were as simple as Asimov's Three Laws of Robotics.

Metallica, Through the Never (Movie, 2013)

It was just added on Netflix. I don't have much to say about it, except:

1) Their continuing belief that they are a live band, and this is how they win people over, is on display here, and it's wrong. The movie is mostly an excuse to get people to watch a whole live show. For people who don't already like Metallica, it's not going to do much for them. For people who do, they'd rather be at a live show.

2) F for use of maguffins. There are two of them. The first is the gasoline, which is not the best one they could have picked and then the bag is introduced too late to be useful or interesting. The main character's motivations for wandering around (and not just going back the way he came when he walks into the middle of a skirmish line between rioters and cops) are never comprehensible and indeed appear not to be considered by the script writers, but at least this is obvious early enough in the movie that you don't waste time trying to figure them out. Add this as support to point #1. Adding this secondary plot was a way to make it seem as if this wasn't just a Metallica concert movie.

Babymetal vs. John Zorn

John Zorn liked to talk about composing in "blocks" and Stockhausen, etc. Now here comes Babymetal:



Compare to a typical Zorn piece, Osaka Bondage (below, from Naked City's Grand Guignol). Zorn is more grating, but the juxtaposition of genres is actually much clearer in the Babymetal piece, which also includes a visual aspect. Note that this is not Zorn-bashing. I've seen him play New Years Eve shows at Tonic. But does it make a difference when someone is doing the same thing mostly for commercial reasons, and not talking about theory, or for that matter selling to people who care about it?) The point is made that Zorn was doing this 25 years ago, but it's interesting that it's now J-pop with the label confidence implied by an obvious budget.




Performances that seem to be deliberately written to fit into certain genres also force us to ask, what differentiates genre self-consciousness from straight parody? Are we sure that John Zorn and Babymetal's songs were not written by Key and Peele? As the world gets wealthier we're swimming in more art and each generation will be better at picking out the essential aspects of each genre, for ridicule or otherwise.

So What If We Find Evidence of Life on Mars?

A new paper in Astrobiology makes claims for possible biogenic origins of structures seen in Martian meteorites. A not unreasonable response is: so what?

If the astrobiology fairy tomorrow gave us incontrovertible evidence of (at least) previous life on Mars, there would be massive public interest and a lot of opportunities for astronomy and basic science in general to get funding; and a whole new surge in interest among young people around the world. Consequently an unqualified "so what" might be the wrong question; "so what in terms of impact to scientific knowledge" is more appropriate. We expect to find life eventually, based on our understanding of the origins of life on Earth. Finding evidence of ancient Martian cells would add more support to our picture of an ancient wet Mars. We might, just might be able to infer something about the cells themselves, but this would be very limited. So life on ancient Mars wouldn't actually be that surprising!

Finding living cells on Mars would be huge. There's definitely a non-zero possibility that cells on Mars and Earth might have the same ancestors, which would actually be kind of boring, but would tell us something about the diffusion of life. But seeing such a novel biochemistry in action, even one that is ultimately related to our own, would give us a lot more information that we could use to understand evolution, biochemistry, and complex systems.

What Do the Patterns in Alternate Histories Say About Us?

For the most recent alternate history (a Buddhist Colony in Ptolemy's Alexandria) go here. This post is also cross-posted to my history and economics blog.

Alternative histories have tended so far to be about events in European (or Western) history, because they're written mostly by European-descended people, and mostly by English-speakers at that.

The test at Sitio Trinidad, 1845, Jornada de Muerte, Nueva Mexico. The test was witnessed by governor Manuel Armijo and president Santa Ana, both of whom lost their vision as a result. (It seems both fission and high speed cameras were developed in nineteenth century Mexico but not dark glasses, go figure.) Despite this setback, the dreaded bomba santabarbara was smuggled in wagons and assembled in Austin and San Antonio and led to the end of the decade-long revuelta tejana and ultimately, the conquest of Alto México (previously the "United States".) Sure it did.


But that's kind of obvious. So even forgetting the (so far) Western focus of what-if fiction, there are two clear patterns that betray some of our assumptions. And the first obvious pattern is: alternate histories are about violence transpiring differently. How many alternate histories involve policy decisions or inventions happening out of order? It's not usually: what if Newton and Leibniz had not developed calculus, or antibiotics had never been invented (or been invented in pre-Mongol-sack Baghdad)? No, the large majority of what we see are the effects of different outcomes of battles and wars. What if Hitler won, what if the North lost Gettysburg, what if Alexander or Jenghiz had not turned around at India and Austria. And this is depressing; because it means either that history is mostly determined by violence, or (even if it's not true) it means that we at least believe that history is mostly determined by violence.

Yes, there are a few stories about political decisions (what if the Ming had not called back the treasure fleets is a favorite) but it's really mostly about if people had killed and dominated each other in a different way.

You could also argue that what we see commercially is not an accurate reflection of our beliefs about history. It's the same answer for why in speculative fiction, dystopias far outnumber utopias. There's clear conflict and thus they're easier to write.

The second pattern, or really observation that students of history can make about this sub-genre: even with battles won or lost differently, it's very hard to find believable changes that affect the outcomes. Sun Tzu was right, the battle usually is won or lost before it begins, and even if the tide on one battlefield had turned, the currents were running one direction or another. For example, so what if Lee won at Gettysburg? A big setback for the Union to be sure, but the Confederacy was screwed from the start in terms of their population and economy. To really get big changes, you have to make major shifts long before the obvious change - the kinds of changes that would have given the South a fighting chance would have had to begin many years before the actual war. Case in point: someone once asked me what might have happened if, in the Mexican War, the Mexican factions had unified against the U.S. as an external threat, and the U.S. lost its first major foreign war and gained no territory. (Or if the U.S. had decided to actually press its 54'40" claim.) A suddenly unified and organized 1840s Mexico is (unfortunately for patriotic Mexicans) only marginally easier to imagine than the first atomic bomb being engineered a hundred years early at Los Alamos by Mexican scientists. Such a story might actually make for some really interesting Latino steampunk fiction, but might as well also include unicorns.

Leonardo DiCaprio Joins Meshuggah

Not really, but if you saw the reddit-borne video below, you might think so for a second. And now there's a petition to have Mr. DiCaprio get onstage with the boys at Bonnaroo - sign it here.

Time Travelers Killing Hitler: A New Take

From the always great SMBC. Here's an argument (based on people in the future are not using it) that time travel will never exist or has no impact for those future people; here's an observation that maybe we're already living in an alternate timeline...

Musicians' Royalties Are Abysmal; Meanwhile, We Should Be Able to Download Songs. ???

Recently I noticed an article making the rounds, which decries the <$1 royalty checks being sent to bands these days. I don't have numbers but it seems the people who are upset about this and forwarding the link, are the same people who get upset when labels protect their product and sue to stop illegal downloading.

Guess what!?!?!? There's a connection!!!!

So to make sure it's clear to everyone, you can have EITHER:

PRODUCT BEING GIVEN AWAY FOR FREE

****OR****

PROFITS TO LABORERS (i.e., musicians)


One or the other. Make up your mind.
