Zipper Merging

Monday, August 4th, 2014

Most people agree that merging early is polite, and merging late is rude, but traffic experts laud the beauty of zipper merging:

It works as follows: in the event of an impending lane closure, drivers should fill in both lanes in equal measure. Within a few car lengths of a lane ending, both lanes’ cars should take turns filling in the open lane and resuming full speed.

If roads are clear enough that everyone is already driving close to the speed limit, zipper merging isn’t as effective, but in the case of congestion, Johnson said that this method reduces backups by a whopping 40 percent on average, since both lanes approach the merge with equal stake in maintaining speed. “When the queue backup is reduced, the access points behind a work zone, like signals or ways to get on and off the freeway, those aren’t blocked,” Johnson pointed out. “People have a better opportunity to get off or on the system at that point.

The Spy Who Loved Frogs

Monday, August 4th, 2014

Herpetologist Edward Taylor led the life of an old-school, adventuring naturalist:

As [Rafe] Brown made his career studying biodiversity in the Philippines over the next two decades, he could not escape Taylor’s long shadow. The elder herpetologist had logged 23 years in the field over his lifetime, collecting more than 75,000 specimens around the world, and naming hundreds of new species.

There is a darker side to Taylor’s legacy, however. He was a racist curmudgeon beset by paranoia — possibly a result of his mysterious double life as a spy for the US government. He had amassed no shortage of enemies by the time he died in 1978. An obituary noted that he was, to many, “a veritable ogre — and woe to anyone who incurred his wrath”. More damaging, perhaps, were the attacks on his scientific reputation. After the loss of his collection in the Philippines, many of the species he had named were declared invalid or duplicates. The standards of taxonomy had advanced beyond Taylor’s quaint descriptions, and without the specimens to refer to, his evidence seemed flimsy.

Capital isn’t a thing

Sunday, August 3rd, 2014

Capital isn’t a thing, Eric Falkenstein says — it’s a ledger, a way of determining who gets the make decisions about various things, and who gets the fruits of those things:

The fact that a minority has most of the power to decide and access the fruits is a consequence of a past where individuals anticipated a future where such a ledger would continue to be valid. It’s always been popular to think, maybe we should have a jubilee, get rid of those ledgers and start again as equals! Given the power law distribution of wealth at all times such a proposal is perennially popular to those ignorant of history. Yet, if you do this every period, capital isn’t owned by any individual, and so would be completely mismanaged as happens in societies without stable property rights. If you do this at all you can expect an immediately higher default premium which would make an economy undercapitalized. Luckily, our Founding Fathers specifically anticipated these problems and so emphasized the republican nature of our government, not making everything a democratic process.

Groundhog Day’s Ecumenical Message

Sunday, August 3rd, 2014

Charles Murray’s last piece of advice for a happy life is to watch Groundhog Day — repeatedly, of course.

Here the late Harold Ramis explains how Groundhog is remarkably ecumenical in its message. (“Embedding disabled by request.”)

All Men Seek to Rule

Saturday, August 2nd, 2014

Status-seeking is a human universal, Eric Falkenstein reminds us:

The anthropologist Harold Schneider studied hunter gatherers and noted they had an almost absence of hierarchy, which he saw as the resulting from the maxim that ‘all men seek to rule, but if they cannot, they seek to be equal.’ It’s a reasonable solution for a society without division of labor.  Unfortunately many progressives see the world the same way, and thus like the Rawlsian solution that everyone has the same outcome regardless of one’s talents or wealth. Now, that’s fine for a camping trip, but in modern society unnecessarily.

Reality shows like Top Chef, Project Ink, Project Runway, or Deadliest Catch show people passionate about activities I do not care about in the least, all private sector jobs. With thousands of different remunerative specialties that complement each other, this allows us to focus and then trade with others to get the benefits of other’s specialization focus. In modernity status isn’t limited to one dimension, and so you can be an important part of something bigger than yourself without joining a religion: you are part of a complex network of specialists in a market economy of individuals maximizing their status in their own individual way.

Everyone wants to live on in the future in some way, as part of heaven or something worldly that needed or at least appreciated you. If you obey the laws and social norms, including The Golden Rule, and generate more revenue than you cost, you are making your tribe better off. The egalitarian solution where we have a single-payer state for everything has no risk, but like Hegel’s farmer, promises little potential for self-actualization or what the Greeks called arête (‘excellence’), which in the modern world is consistent with specialization, trade, and productivity growth (arête incents one to do things better than before).  We shouldn’t base our norms on hunter gatherers, which is why most people don’t.

The Guy in the Model Shop that Everyone Hated

Saturday, August 2nd, 2014

James Cameron describes his early work for Roger Corman:

I had been sort of preparing myself for a career in visual effects by learning about mold-making and sculpting and matte camera and optical printing on little film projects in Orange County with some other eager wannabes. And we got a lead that there was a film being made up in Venice with visual effects for Roger Corman. I knew who Roger Corman was, and I knew the films he had made.

So I trooped down there, and they had an opening for a modeler. I started off as the lowest man on the totem pole in the model shop. I was just happy to be on a film — I didn’t care that it was a pretty rinky-dink production. This was at the lumberyard, which was basically just an empty building with a floor that was flooded.

Roger came through one day, and he kind of threw down a challenge to everyone in the model shop. Actually, he was kind of pissed off. We’re so many weeks away from shooting, and no one had even designed the main character ship for Battle Beyond the Stars.

The main space ship had a female computer. It was kind of a HAL 9000, but female. He said, ‘I want a design in the next two days.’ So it sort of became a sort of design contest, and I thought, OK, it’s Roger Corman. He does girls-in-bamboo-cages movies. What is he selling? He sells tits! So I designed a kind of Amazon warrior spaceship — basically a spaceship with tits. It was a cool design.

Roger came through and he looked at all of the designs, and he stopped at mine and he went: ‘This is it, this is exactly what I want.’ He said, ‘What is this?’ And I said, ‘This is a spaceship with tits.’ And he says, ‘Yes, that’s exactly what it is. You build it.’ So suddenly, I was the guy in the model shop that everyone hated.

Movie Film at Death’s Door

Kodak’s motion-picture film sales have plummeted 96% since 2006, the Wall Street Journal reports — from 12.4 billion linear feet to an estimated 449 million this year:

With the exit of competitor Fujifilm Corp. last year, Kodak is the only major company left producing motion-picture film.

Not More, Better

Friday, August 1st, 2014

The government spends about 35% of GDP in the US today, Eric Falkenstein notes, and heavily regulates the rest:

It would be far better if, instead of thinking about new tricky ways to squeeze the rich, we instead set government spending to some fraction (say 35%) of the past 5 years of GDP and no more. The endless arguments about the level would stop, and it’s interesting to note that over the past 30 years in the US federal revenues as a percent of GDP has been remarkably consistent across various administrations. By using a moving average of historical GDP this would make spending countercyclical, most importantly instead of politicians being elected for their ability to promise ‘more’ they would instead focus on ‘better.’ That is, it would be nice if the politicians argued about better ways to allocate spending rather than about more or less in aggregate; the net result of the ‘more’ approach has been those who are good at articulating why we need more find they have no idea how to spend it, as when the government had $800B to spend in stimulus, most of it simply went to shoring up state budgets, meaning, state pension deficits, which is just an income transfer to state employees from future taxpayers.
