Politics, Weather, Photography, and the Dog

It doesn't work like that!

Jimmy Carter captained nuclear missile submarines. Bill Clinton was a Rhodes Scholar. Barack Obama was a Constitutional Law professor at one of the top-5 law schools in the country.

Donald Trump thinks...well, I'll let Japan Times explain:

Trump said ‘samurai’ Japan should have shot down overflying North Korean missiles

U.S. President Donald Trump has said Japan should have shot down the North Korean missiles that flew over the country before landing in the Pacific Ocean earlier this year, diplomatic sources have said, despite the difficulties and potential ramifications of doing so.

The revelation came ahead of Trump’s arrival in Japan on Sunday at the start of his five-nation trip to Asia. Threats from North Korea’s nuclear weapons and missile development programs were set to be high on the agenda in his talks with Prime Minister Shinzo Abe on Monday.

Trump questioned Japan’s decision not to shoot down the missiles when he met or spoke by phone with leaders from Southeast Asian countries over recent months to discuss how to respond to the threats from North Korea, the sources said.

[T]he Self-Defense Forces did not try to intercept the missiles, with the government saying the SDF had monitored the rockets from launch and judged they would not land on Japanese territory.

But the altitude and speed of the missiles would have made it very difficult to destroy them in flight, while failure would have been embarrassing for Japan and encouraging to North Korea.

Defense Ministry officials confirmed this view and said there were also legal issues to clear.

Reagan thought we could call back nuclear missiles. Trump thinks we can shoot them down. And the Republican rank-and-file think we who want competent leadership are elitists.

We might be doomed.

Los Angeles of the future

Carl Abbot, writing for CityLab, discusses Blade Runner's impact:

Blade Runner fused the images, using noir atmosphere to turn Future Los Angeles into something dark and threatening rather than bright and hopeful. Flames randomly burst from corporate ziggurats. Searchlights probe the dark sky. But little light reaches the streets where street merchants and food cart proprietors compete with sleazy bars—a setting that Blade Runner 2049 revisits. The dystopic versions of New York in Soylent Green and Escape from New York are set in a city crumbling from age and overuse. In contrast, Blade Runner uses the imagery of the future for similar stories of deeply embedded inequality.

When it comes down to it, of course, there’s more fun and schadenfreude in imagining trouble striking a big city than a small town. Terminator 2: Judgment Day would not be half so exciting if T-1000 chased Arnold Schwarzenegger along the banks of the puny Miami River in Dayton, Ohio, rather than the concrete arroyo of the Los Angeles River. In the 1980s, the fictional destruction of New York was old hat. Los Angeles was a relatively fresh target and, for the film industry, a logistically convenient one. Moviegoers were increasingly willing to disparage it, too.

Blade Runner was a catalyst for a dystopian decade that was accentuated by the rioting and violence that followed the April 1992 acquittal of police officers accused of beating Rodney King. Moviegoers would soon get Falling Down, whose filming was interrupted by the Rodney King riots, Pulp Fiction, and Independence Day, with its total obliteration of the metropolis. In print in the early 1990s were Neal Stephenson’s Snow Crash, Cynthia Kadohata’s In the Heart of the Valley of Love, and Octavia Butler’s Parable of the Sower, all depicting a near-future Los Angeles fragmenting into enclaves and drifting toward chaos, capped by Mike Davis’s The Ecology of Fear.

 

I've got tickets to Blade Runner 2049 already. Can't wait.

Pirates may be to blame for the U.S. not being Metric

The Système International d'unités, also known as the Metric System, is the most widely-used system of measuring things in the known universe. Of the 7.57 billion people in the world, somewhere around 7.2 billion use SI. The laggards are almost all here in the United States.

Sarah Kaplan, writing for the Washington Post Science Alert today, blames English privateers:

In 1793, botanist and aristocrat Joseph Dombey set sail from Paris with two standards for the new "metric system": a rod that measured exactly a metre, and a copper cylinder called a "grave" that weighed precisely one kilogram.

He was journeying all the way across the Atlantic to meet Secretary of State Thomas Jefferson - a fellow fan of base-ten systems who, Dombey hoped, would help persuade Congress to go metric.

Then a storm rolled in, knocking Dombey's ship off course. The unlucky academic was washed into the Caribbean - and straight into the clutches of British pirates.

The brigands took Dombey hostage and looted his equipment. The luckless scientist died in prison shortly after his capture; his belongings were auctioned off to the highest bidders.

France sent a second emissary to promote the metric system. But by the time the replacement arrived, America had a new secretary of state, Edmund Randolph, who apparently didn't care much for measurement.

As the person who sent me this article said, perhaps the pirates just preferred saying "yarrrrd?"

But really, I put this into the same category of "American exceptionalism" that keeps us executing criminals, not getting passports, and thinking that we're somehow #1.

Under vacuum

So, this might be happening at my house next weekend:

The "sous vide" part of sous vide cooking refers to the vacuum-sealed bags that are often called for when you're using the technique. (The French phrase literally means "under vacuum.") However, these days, when someone says "sous vide cooking," they're generally referring to any kind of cooking that takes place in a precisely temperature-controlled water bath, whether you're actually using a vacuum-sealed bag or not.

Sous vide cooking offers unparalleled control over whatever it is you are trying to cook, whether it's steaks and chopsshrimp and lobstervegetables, or even large cuts of meat like pork shouldersand legs of lamb. With fast-cooking foods, like steaks and chicken breasts, sous vide removes all the guesswork involved in traditional methods. No poking with a thermometer, no cutting and peeking, no jabbing with your finger—just perfect results every single time.

A sous vide circulator mysteriously arrived at Inner Drive World Headquarters yesterday. We're going to start with eggs and work our way up to a venison steak. Yum.

Statistical sins: smoking v. e-cigratettes

Deeply Trivial finds evidence for why there is little evidence about the safety of e-cigarettes:

[T]he statistical sin here isn't really something the researchers have done (or didn't do). It's an impossibility created by confounds. How does one recruit people who have only smoked e-cigarettes or who at least have very little experience with regular cigarettes? What's happening here is really an issue of contamination - a threat to validity that occurs when the treatment of one group works its way into another group. Specifically, it's a threat to internal validity - the degree to which our study can show that our independent variable causes our dependent variable. In smoking research, internal validity is already lowered, because we can't randomly assign our independent variable. We can't assign certain people to smoke; that would be unethical. Years and years of correlational research into smoking has provided enough evidence that we now say "smoking causes cancer." But technically, we would need randomized controlled trials to say that definitively. 

That's not to say I don't believe there is a causal link between smoking and negative health outcomes like cancer. But that the low level of internal validity has provided fuel for people with an agenda to push (i.e., people who have ties to the tobacco industry or who otherwise financially benefit from smoking). Are we going to see the same debate play out regarding e-cigarettes? Will we have to wait just as long for enough evidence to accrue before we can say something definitive about e-cigarettes?

For my part, their safety or lack of to the smoker makes little difference to me. I just don't like people blowing their exhaust fumes into my environment.

Replicating climate change denial papers

A new paper in the journal Theoretical and Applied Climatology tries to replicate the most-referenced papers in the 3% minority that find alternate explanations for human-caused global warming. Turns out, the deniers are still looking for their Galileo:

This new study was authored by Rasmus Benestad, myself (Dana Nuccitelli), Stephan Lewandowsky, Katharine Hayhoe, Hans Olav Hygen, Rob van Dorland, and John Cook. Benestad (who did the lion’s share of the work for this paper) created a tool using the R programming language to replicate the results and methods used in a number of frequently-referenced research papers that reject the expert consensus on human-caused global warming. In using this tool, we discovered some common themes among the contrarian research papers.

Cherry picking was the most common characteristic they shared. We found that many contrarian research papers omitted important contextual information or ignored key data that did not fit the research conclusions.

We found that the ‘curve fitting’ approach also used in the Humlum paper is another common theme in contrarian climate research. ‘Curve fitting’ describes taking several different variables, usually with regular cycles, and stretching them out until the combination fits a given curve (in this case, temperature data). It’s a practice I discuss in my book, about which mathematician John von Neumann once said, "With four parameters I can fit an elephant, and with five I can make him wiggle his trunk."

This represents just a small sampling of the contrarian studies and flawed methodologies that we identified in our paper; we examined 38 papers in all. As we note, the same replication approach could be applied to papers that are consistent with the expert consensus on human-caused global warming, and undoubtedly some methodological errors would be uncovered. However, these types of flaws were the norm, not the exception, among the contrarian papers that we examined.

You can count the insurance industry among the groups that believe the science is settled. Insurers appear to have started looking at climate change as an inevitability, not a risk, which changes their models radically:

[F]lood insurance was not a lucrative business to begin with. Congress set up the National Flood Insurance Program in 1968 as it became clear that private companies couldn’t profitably provide coverage. Now, nearly half a century later, the program is—ahem—under water by $24.6 billion. As a result, there’s a push to move flood insurance toward the private market. That could mean less building in flood-prone areas, as they become effectively uninsurable thanks to sky-high rates. Says Morningstar’s Brett Horn: “Frankly, that’s not a bad outcome.”

Meanwhile, the second major hurricane of the season is heading for Florida...

Just add water

...to your whisky:

[A]dding water releases molecules that improve the flavor. Water and ethanol don’t make for a perfectly uniform mixture. Aromatic compounds could become trapped in ethanol clusters and never reach the surface. Our tongues are only capable of identifying the flavors, sweet, salty, sour, bitter, and umami (savory), so aroma is really important for detecting all the other flavors that connoisseurs appreciate in whiskey.

Guaiacol is what gives whiskey that smoky, spicy, peaty flavor. Chemically, guaiacol is similar to a lot of other whiskey aroma compounds like vanillin (with the scent of vanilla) and limonene (citrus). These and other flavor compounds are not attracted to water and are more likely to become trapped in ethanol clusters.

So, just add a couple of drops to your dram, especially if it's cask-strength. But start with good whisky; diluting crap won't improve it.

Forty years ago today

...the United States launched a space probe that is now one of the three fastest-moving and farthest human-made objects in the universe.

Voyager 2 lifted off from Cape Canaveral, Florida, at 9:29 CDT on 20 August 1977. As of today it's about 115 AUs (1.72×1010 km) from Earth, moving about 15.4 km/s or 55,000 km/h away from the sun.

It's still alive. NASA expects the probe to continue transmitting from interstellar space for at least another 7 years, by which time it may be able to sample the interstellar medium itself.

Happy birthday, V'GER. We hope to see you again someday.

New hints about dog domestication

Via Deeply Trivial, a new study published last week provides new evidence that only a few genetic changes made wary wolves into friendly dogs:

Not much is known about the underlying genetics of how dogs became domesticated. In 2010, evolutionary geneticist Bridgett vonHoldt of Princeton University and colleagues published a study comparing dogs’ and wolves’ DNA. The biggest genetic differences gave clues to why dogs and wolves don’t look the same. But major differences were also found in WBSCR17, a gene linked to Williams-Beuren syndrome in humans.

Williams-Beuren syndrome leads to delayed development, impaired thinking ability and hypersociability. VonHoldt and colleagues wondered if changes to the same gene in dogs would make the animals more social than wolves, and whether that might have influenced dogs’ domestication.

The team notes, for instance, that in addition to contributing to sociability, the variations in WBSCR17 may represent an adaptation in dogs to living with humans. A previous study revealed that variations in WBSCR17 were tied to the ability to digest carbohydrates — a source of energy wolves would have rarely consumed. Yet, the variations in domestic dogs suggest those changes would help them thrive on the starch-rich diets of humans.

I hope they're not barking up the wrong tree here.

Bias in science?

Two stories today about science, one implicitly about how money influences reported outcomes, and another about how people don't really understand science.

First, the New York Times reported Monday on a $100m National Institutes of Health clinical trial that is getting $67m indirectly from five major alcohol producers:

[T]he mantra that moderate drinking is good for the heart has never been put to a rigorous scientific test, and new research has linked even modest alcohol consumption to increases in breast cancer and changes in the brain. That has not stopped the alcoholic beverage industry from promoting the alcohol-is-good-for-you message by supporting scientific meetings and nurturing budding researchers in the field.

Five companies that are among the world’s largest alcoholic beverage manufacturers — Anheuser-Busch InBev, Heineken, Diageo, Pernod Ricard and Carlsberg — have so far pledged $67.7 million to a foundation that raises money for the National Institutes of Health, said Margaret Murray, the director of the Global Alcohol Research Program at the National Institute on Alcohol Abuse and Alcoholism, which will oversee the study.

George F. Koob, the director of the alcohol institute, said the trial will be immune from industry influence and will be an unbiased test of whether alcohol “in moderation” protects against heart disease. “This study could completely backfire on the alcoholic beverage industry, and they’re going to have to live with it,” Dr. Koob said.

“The money from the Foundation for the N.I.H. has no strings attached. Whoever donates to that fund has no leverage whatsoever — no contribution to the study, no input to the study, no say whatsoever.” But Dr. Koob, like many of the researchers and academic institutions playing pivotal roles in the trial, has had close ties to the alcoholic beverage industry.

Keep in mind, funding does not automatically create bias. But it does make people wonder about the study's legitimacy. (This is an enormous problem in elections, too.)

When people start doubting the legitimacy of a study—or an entire body of research—we can get into real trouble. In an op-ed in today's Washington Post, climate scientist Ben Santer explains how he's fighting back against ignorance:

After decades of seeking to advance scientific understanding, reality suddenly shifts, and you are back in the cold darkness of ignorance. The ignorance starts with President Trump. It starts with untruths and alternative facts. The untruth that climate change is a “hoax” engineered by the Chinese. The alternative fact that “nobody really knows” the causes of climate change. These untruths and alternative facts are repeated again and again. They serve as talking points for other members of the administration. From the Environment Protection Agency administrator, who has spent his career fighting against climate change science, we learn the alternative fact that satellite data show “leveling off of warming” over the past two decades. The energy secretary tells us the fairy tale that climate change is due to “ocean waters, and this environment in which we live.” Ignorance trickles down from the president to members of his administration, eventually filtering into the public’s consciousness.

I have to believe that even in this darkness, though, there is still a thin slit of blue sky. My optimism comes from a gut-level belief in the decency and intelligence of the people of this country. Most Americans have an investment in the future — in our children and grandchildren, and in the planet that is our only home. Most Americans care about these investments in the future; we want to protect them from harm. That is our prime directive. Most of us understand that to fulfill this directive, we can’t ignore the reality of a warming planet, rising seas, retreating snow and ice, and changes in the severity and frequency of droughts and floods. We can’t ignore the reality that human actions are part of the climate-change problem, and that human actions must be part of the solution to this problem. Ignoring reality is not a viable survival strategy.

People are attacking truth on several fronts. We've got to keep fighting.
