game of (bee) thrones

Queen bees demand, and receive, absolute loyalty from their hives. When they are nearing the end of their reigns, they try to arrange to keep their family in power and have one of their daughters assume the throne. But that doesn’t always work out and the struggle over succession can be pretty brutal. This might give George R.R. Martin some ideas.

As far as I can tell, my queen died sometime in the spring. Queens typically live for about four or five years, so this caught me by surprise. A new queen, however, is a regular event in the life of a hive. Beekeepers frequently replace their queens every year or two to introduce genetic variety and ensure that the hive has a strong monarch who can lay enough eggs to keep the population up. Bees can also raise their own queen, and when I did an inspection early that spring, I was pleased to see that mine had taken the initiative. Before she died, my old queen must have laid a few fertilized eggs that worker bees raised as replacements. They would have selected six or seven fertilized (female) eggs and fed them only royal jelly. When the first queen hatched, she would have immediately killed any unhatched competition and ideally flown a few mating flights, storing enough semen in her abdomen to spend the rest of her life laying eggs.

While a newborn queen may seem ruthless, the success of a beehive hinges on allegiance to its queen. Though she can mate with an average of 12 different drones, there is only one queen, which makes for a hive of closely related bees. As a new queen begins to produce her own pheromones, the hive slowly aligns with her as the old bees die and new workers hatch. In a sense, the hive is genetically wired to be loyal to the monarchy. If the hive was to raise multiple queens, or if the workers were to start laying eggs, the interests of the population would slowly fracture…

Bees have about 165 pheromone receptors on their antennae and though it’s not entirely clear how workers “decide” what to do and when (the question of agency is still very much up for debate), it is certain that the queen’s pheromones prompt them to go about their business. When the reigning monarch dies or stops laying eggs in her old age, the change in her pheromones prompts the hive to raise a replacement, as my hive had done. Similarly, if a new queen arrives and releases her pheromones before those of the old queen have dispersed, the hive will consider the new queen an invader, and kill her. Above all, they are loyal to their queen. I did not fully grasp this fact. Because I waited only six hours between queens, the worker bees probably stung my new queen to death within an hour.

lugenpresse

Today’s German lesson: lugenpresse translates literally as “lying press”, but it wouldn’t be much of a stretch to translate it as “fake news”. In fact, the German version was heard at rallies during the Trump campaign apparently. This is a bit of history on the term from the Washington Post:

A decade later [the 1920s], it had turned into an explosive and stigmatizing propaganda slogan, used to stir hatred against Jews and communists. Critics of Adolf Hitler’s regime were frequently referred to as members of the “Lügenpresse apparatus.”

Until today, the word has an anti-Semitic connotation, and it implies hatred not only against journalists but against everyone who opposes the “will of the people.” That abstract concept emerged during World War II when Hitler sought to propagate the idea that Germans were a “master race” superior to all others, especially Jews and Slavic people.

The consequences of that rhetoric — of which the term “Lügenpresse” was an important component under propaganda minister Joseph Goebbels — were horrifying. Millions of people were killed in concentration camps by the Nazis, including Jews, political opponents and homosexuals.

Trump is ignorant of history at a minimum, and I think he has fascist tendencies. But I am only now beginning to think he is using actual, thinly-veiled Nazi-inspired propaganda. It’s evil.

 

the decline and fall of the U.S. empire

Okay, it is not falling quite yet, but The Intercept has a review of two books that make a persuasive case we are witnessing its decline.

Wright sees the system under threat from a combination of newly emerging powers and recent American missteps. McCoy, for his part, sees the unraveling of the U.S. empire as analogous to the series of events that led to the decline of the British and French empires before it. The first step is the loss of support from local elites in territories under imperial influence, a process that McCoy says is clearly underway for the U.S. in many critical regions of the world. In recent years, America has seen its ties strained with military partners such as Turkey, the Philippines, Pakistan, and Saudi Arabia, while major U.S. allies like Germany and South Korea have increasingly come to question America’s capacity to continue leading the imperial system that it created.

It is the Arab Spring uprisings against mostly pro-U.S. dictators, however, that McCoy says marked the slow beginning of the end of American imperium. While the revolts are widely judged to have failed in bringing about liberal democracy, they did succeed in unseating longtime American allies in Tunisia and Egypt, while straining U.S. ties with Gulf Arab countries and even Iraq. As McCoy writes, “All modern empires have relied on dependable surrogates to translate their global power into local control.” He adds, “For most of them, the moment when those elites began to stir, talk back, and assert their own agendas was also the moment when you knew that imperial collapse was in the cards.” The British empire famously became a “self-liquidating concern” when local elites across the empire began demanding self-rule, as did France’s far-flung rule when it was forced to wage a grinding war of attrition to keep control over Algeria. The Arab Spring and the forces it unleashed, which have reduced U.S. influence while exhausting its resources to deal with terrorism and migration, “may well contribute, in the fullness of time, to the eclipse of American global power…”

Partly as a consequence of so many self-inflicted losses, China, Russia, and Iran have all mounted growing challenges to American hegemony in recent years, contesting the tenets of the U.S.-enforced order in the South China Sea, eastern Europe and the Middle East, respectively. Russia has successfully annexed territory and asserted its influence along its periphery, in places like Ukraine, while China has moved ahead with plans to put the economically-vital South China Sea region under its control. Instead of a world in which a hegemonic U.S. enforces the political and economic rules of engagement in these regions, its now possible to see a future in which the world is carved up into a “spheres of influence” system that gives regional powers wide latitude to set the agenda in their immediate neighborhood.

Love the republic, hate the empire. Or at least let the empire go and maybe breathe a sigh of relief to let some of the self-imposed responsibility go with it. But if we are going to do that, we need to support and strengthen international institutions that promote peace, trade, and human rights. Instead we seem to be abandoning those institutions at the same time we are abdicating responsibility.

Carl Sagan’s Baloney Detection Kit

In this essay Carl Sagan suggests a set of guidelines for using the scientific method to decide if something is true.

  • Wherever possible there must be independent confirmation of the “facts.”
  • Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.
  • Arguments from authority carry little weight—“authorities” have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
  • Spin more than one hypothesis. If there’s something to be explained, think of all the different ways in which it could be explained. Then think of tests by which you might systematically disprove each of the alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among “multiple working hypotheses,” has a much better chance of being the right answer than if you had simply run with the first idea that caught your fancy.
  • Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don’t, others will.
  • · Quantify. If whatever it is you’re explaining has some measure, some numerical quantity attached to it, you’ll be much better able to discriminate among competing hypotheses. What is vague and qualitative is open to many explanations. Of course there are truths to be sought in the many qualitative issues we are obliged to confront, but finding them is more challenging.
  • If there’s a chain of argument, every link in the chain must work (including the premise) not just most of them.
  • Occam’s Razor. This convenient rule-of-thumb urges us when faced with two hypotheses that explain the data equally well to choose the simpler.
  • Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable, unfalsifiable, are not worth much. Consider the grand idea that our Universe and everything in it is just an elementary particle—an electron, say—in a much bigger Cosmos. But if we can never acquire information from outside our Universe, is not the idea incapable of disproof? You must be able to check assertions out. Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and see if they get the same result.

He goes on to “round out the toolkit” with a list of logical fallacies and rhetorical tricks to be aware of.

Gorbachev’s 1992 Speech at Westminster College

From the New York Times archives, May 7, 1992:

Mr. Gorbachev spoke to an outdoor gathering and offered a range of proposals for strengthening the United Nations. These included the enlargement of the Security Council and the application of stronger sanctions and military force against wayward members

In particular, he called for creation of a “special body” to use economic and military means to prevent regional conflicts and for a greatly enlarged Security Council, with nations like India, Japan, Poland, Mexico, Germany, Brazil, Canada, Indonesia and Egypt as members, even if without veto power…

Today, Mr. Gorbachev stood at the same lectern as Churchill to symbolize the Soviet Union’s peaceful demise and to look no less uncertainly into the future, hoping this time that nations “made wise by bitter experience” might cast aside “egoistic considerations in order to arrive at the exalted goal that is man’s destiny on earth.”

A nice vision, and good advice. The world has not taken his advice and has not lived up to his vision.

utility-scale solar cost dropped 30% in one year

According to Inhabitat:

In a recently published report, the US Department of Energy’s National Renewable Energy Laboratories documented that the cost of utility-scale solar, generated from large plants rather than residential rooftops, has decreased by 30 percent within the past year…

Although China has frequently been cited by the US President as a dangerous competitor, the solar renaissance in the United States has been made possible because of the pioneering work in solar energy being done in the People’s Republic. More solar modules are being produced in China than there is demand, which has enabled US importers to purchase this technology at low prices. As a result, the average price per watt is now only $1.03 for fixed-tilt systems and $1.11 for those that move to track the sun’s movement.

rapid intensification

The 2017 hurricane season has set new records for rapid intensification, according to the Washington Post.

“It’s not a common event. Typically, that occurs in maybe 5 percent of our forecasts,” said Mark DeMaria, acting deputy director of the National Hurricane Center…

“Looking back through the records, Maria went from a tropical depression to a Category 5 hurricane in just two and a half days,” he said. “I couldn’t find any other tropical cyclones in our historical record that went that quickly from a depression to a Category 5 hurricane…”

The National Hurricane Center technically defines rapid intensification as a wind speed increase of at least 35 miles per hour in 24 hours. All four of the most intense Atlantic storms in 2017 beat that easily.

We can’t say any individual event is caused by climate change, say the experts, but some weird shit is going to happen and it is going to happen more often.

“Cities Swimming in Raw Sewage as Hurricanes Overwhelm Systems”

That headline sounds bad, but it’s actually bad journalism. Sewers and wastewater treatment plants are not designed to function correctly during a hurricane the size of Harey or Irma. In that situation, the concern is protecting life and property. Sewage treatment can take a temporary back seat, and generally be brought back online pretty quickly after the extreme event is over.

Millions of gallons of poorly treated wastewater and raw sewage flowed into the bays, canals and city streets of Florida from facilities serving some of the nation’s fastest-growing counties. More than 9 million gallons of releases tied to Irma have been reported as of late Tuesday as inundated plants were submerged, forced to bypass treatment or lost power.

The article goes on to suggest that the sewage released during a hurricane has something to do with aging, poorly maintained infrastructure that is not doing what it is supposed to do in normal weather.

Such overflows, which can spread disease-causing pathogens, are happening more often, as population shifts and increasingly strong storms strain the capacity of plants and decades-old infrastructure. The Environmental Protection Agency estimated last year that $271 billion is needed to maintain and improve the nation’s wastewater pipes, treatment plants and associated infrastructure…

Wastewater treatment facilities are especially vulnerable to flooding because they are traditionally built in low-lying areas, near whatever river or waterway they discharge into.  That approach works in normal conditions, but coastal treatment plants increasingly are outmatched during intense downpours and fierce storms, especially amid rising sea levels.

“Any time there is a large event — any kind of flood — they get overwhelmed and you have these raw sewage discharges,” said Ken Kopocis, who served as the top official in the EPA’s water office under President Barack Obama.

This is all true. We do need to spend money on our water quality infrastructure, and states and the federal government need to help fix problems that were caused long before anyone alive today was born. And we need to consider climate change and sea level rise when we do all that. But we also need to demand a bit more from our science reporters.

the “Scopes Monkey Trial of the 21st Century”

From Bloomberg BNA,

A federal judge said he wanted to avoid having “the Scopes Monkey Trial of the 21st Century,” and ordered an environmental organization to remove claims based on climate change in its lawsuit against Exxon Mobil Corp.

Judge Mark Wolf said he did not want the lawsuit to turn into a trial about whether climate change exists, the way the 1925 trial about whether evolution could be taught in Tennessee public schools took up the debate about human origin…

Wolf said he would not dismiss the suit. But he told the environmental organization to amend its 14-count complaint and strip out major references to harm caused by climate change that would take place in 2050 and later.

I hadn’t thought of it before but I think the comparison is perfect! Almost 100 hundred years on from the Scopes trial, a large majority of rational, educated people correctly see that debate as a silly footnote to an ignorant, bygone era. Climate change is similar, except we were never seriously worried about the apes rising up and swamping us (you maniacs!)

But on a more serious note, why is a judge qualified to identify the best planning horizon when considering risk of failure of an industrial facility? That should depend on the expected life of the facility, external threats that might occur (like climate change), likelihood and consequence of failure during that period. If an oil and gas tank farm would tend to be retired or rebuilt every 30 years or so (and I suspect it might), it would make sense to take into account only the risks expected to take place over that time period, so 2050 might actually be a reasonable decision.

alternatives to word clouds

I like this post on R bloggers proposing several alternatives to word clouds. I’ll list them below but really, you should look at the pictures because hey, this is about pictures.

  1. circle packing (basically this replaces the words with circles, dealing with the problem of bigger/longer words appearing to be more important in standard word clouds); there is a variation on this called the “horn of plenty” where the circles are arranged in order rather than randomly
  2. cartogram (in my ignorance, I have been calling this a “bubble map”. I have used these frequently to show engineering model results and find they work well for many people)
  3. chloropleth (these shade in geographic areas to convey data. I find these work well if the size of the geographic area is important information. If it is not, these tend to draw the viewer’s eye to larger areas, and in that case the bubbles are better. For example, per-person income of Luxembourg vs. China.)
  4. treemap (I’ve been calling these “packed rectangles” and I generally find them good for anything where conveying relative magnitudes of things to people is important)
  5. donuts (surpringly, the author concludes a donut is the best option for the data he is trying to show and I kind of agree, it gets the point across and leaves lots of room for labels)
