July 2019 in Review

Most frightening and/or depressing story: Most hopeful story: Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both:
  • I laid out the platform for my non-existent Presidential campaign.

deliberate practice

Open Culture has a post with lots of links to ideas on the best ways to practice something new. Hint: just repeating bad habits doesn’t do the trick.

Psychologist Anders Ericsson, the single figure most closely associated with deliberate practice, draws a distinction with what he calls naive practice: “Naive practice is people who just play games,” and in so doing “just accumulate more experience.” But in deliberate practice, “you actually pinpoint something you want to change. And once you have that specific goal of changing it, you will now engage in a practice activity that has a purpose of changing that.”

So it turns out that experience and wisdom aren’t the same thing after all. I would say you can’t have wisdom without experience, but you can have experience without wisdom.

May 2019 in Review

This wasn’t my most prolific writing (or reading) month ever. In fact, it my have been my worst. But here are a few highlights of what I did get around to.

Most frightening and/or depressing story:

  • Without improvements in battery design, the demand for materials needed to make the batteries might negate the environmental benefits of the batteries. I’m not really all that frightened or depressed about this because I assume designs will improve. Like I said, it was slim pickings this month.

Most hopeful story:

  • Planting native plants in your garden really can make a difference for biodiversity.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both:

  • Joseph Stiglitz suggested an idea for a “free college” program where college is funded by a progressive tax on post-graduation earnings.

 

data-driven economics 101

This article in Vox is about an entirely data-driven approach to introductory economics. The idea of asking students to discover their own theories is an interesting one, but in most fields I do think there is an established body of theory and standard practice that students should learn before they are qualified to go off reinventing their own wheels. If a new generation doesn’t know what they don’t know, they have to reinvent everything and society doesn’t make progress.

Isaac Asimov’s guide to the Bible

In 1968, Isaac Asimov released a guide to the Bible. According to Open Culture,

“I am trying,” Asimov writes in his introduction, “to bring in the outside world, illuminate it in terms of the Biblical story and, in return, illuminate the events of the Bible by adding to it the non-Biblical aspects of history, biography, and geography.” This describes the general methodology of critical Biblical scholars. Yet Asimov’s book has a distinct advantage over most of those written by, and for, academics. Its tone, as one reader comments, is “quick and fun, chatty, non-academic.” It’s approachable and highly readable, that is, yet still serious and erudite.

Asimov’s approach in his guide is not hostile or “anti-religious,” as another reader observes, but he was not himself friendly to religious beliefs, or superstitions, or irrational what-have-yous. In the interview above from 1988, he explains that while humans are inherently irrational creatures, he nonetheless felt a duty “to be a skeptic, to insist on evidence, to want things to make sense.” It is, he says, akin to the calling believers feel to “spread God’s word.” Part of that duty, for Asimov, included making the Bible make sense for those who appreciate how deeply embedded it is in world culture and history, but who may not be interested in just taking it on faith.

2018 in Review

Most frightening and/or depressing stories:

  • JANUARY: Cape Town, South Africa looked to be in imminent danger of running out of water. They got lucky, but the question is whether this was a case of serious mismanagement or an early warning sign of water supply risk due to climate change. Probably a case of serious mismanagement of the water supply while ignoring the added risk due to climate change. Longer term, there are serious concerns about snowpack-dependent water supplies serving large urban populations in Asia and western North America.
  • FEBRUARY: Cape Town will probably not be the last major city to run out of water. The other cities at risk mentioned in this article include Sao Paulo, Bangalore, Beijing, Cairo, Jakarta, Moscow, Istanbul, Mexico City, London, Tokyo, and Miami.
  • MARCH: One reason propaganda works is that even knowledgeable people are more likely to believe a statement the more often it is repeated.
  • APRIL: That big California earthquake is still coming.
  • MAY: The idea of a soft landing where absolute dematerialization of the economy reduces our ecological footprint and sidesteps the consequences of climate change through innovation without serious pain may be wishful thinking.
  • JUNE: The Trump administration is proposing to subsidize coal-burning power plants. Meanwhile the long-term economic damage expected from climate change appears to be substantial. For one thing, Hurricanes are slowing down, which  means they can do more damage in any one place. The rate of melting in Antarctic ice sheets is accelerating.
  • JULY: The UN is warning as many as 10 million people in Yemen could face starvation by the end of 2018 due to the military action by Saudi Arabia and the U.S. The U.S. military is involved in combat in at least 8 African countries. And Trump apparently wants to invade Venezuela.
  • AUGUST: Noam Chomsky doesn’t love Trump, but points out that climate change and/or nuclear weapons are still existential threats and that more mainstream leaders and media outlets have failed just as miserably to address them as Trump has. In related news, the climate may be headed for a catastrophic tipping point and while attention is mostly elsewhere, a fundamentalist takeover of Pakistan’s nuclear arsenal is still one of the more serious risks out there.
  • SEPTEMBER: A huge earthquake in the Pacific Northwest could be by far the worst natural disaster ever seen.
  • OCTOBER: The Trump administration has slashed funding to help the U.S. prepare for the next pandemic.
  • NOVEMBER: About half a million people have been killed in Iraq, Afghanistan, and Pakistan since the U.S. invasions starting in 2001. This includes only people killed directly by violence, not disease, hunger, thirst, etc.
  • DECEMBER: Climate change is just bad, and the experts seem to keep revising their estimates from bad to worse. The Fourth National Climate Assessment produced by the U.S. government is not an uplifting publication. In addition to the impacts of droughts, storms, and fires, it casts some doubt on the long-term security of the food supply. An article in Nature was also not uplifting, arguing that climate change is happening faster than expected due to a combination of manmade and natural trends.

Climate change, nuclear weapons, and pandemics. If I go back and look at last year’s post, this list of existential threats is going to be pretty much the same. Add to this the depressing grind of permanent war which magnifies these risks and diverts resources that could be used to deal with them. True, we could say that we got through 2018 without a nuclear detonation, pandemic, or ecological collapse, and under the circumstances we should sit back, count our blessings, and wait for better leadership. And while our leadership is particularly inept at the moment, I think Noam Chomsky has a point that political administration after political administration has failed to solve these problems and this seems unlikely to improve. The earthquake risk is particularly troublesome. Think about the shock we felt over the inept response to Katrina, and now think about how essentially the same thing happened in Puerto Rico, we are not really dealing with it in an acceptable way, and the public and news media have essentially just shrugged it off and moved on. If the hurricanes, floods, fires and droughts just keep hitting harder and more often, and we don’t fully respond to one before the next hits, it could mean a slow downward spiral. And if that means we gradually lose our ability to bounce back fully from small and medium size disasters, a truly huge disaster like an epic earthquake on the west coast might be the one that pushes our society to a breaking point.

Most hopeful stories:

I believe our children are our future…ya ya blahda blahda. It’s a huge cliche, and yet to be hopeful about our world I have to have some hope that future generations can be better system thinkers and problem solvers and ethical actors than recent generations have been. Because despite identifying problems and even potential solutions we are consistently failing to make choices as a society that could divert us from the current failure path. And so I highlighted a few stories above about ideas for better preparing future generations, ranging from traditional school subjects like reading and music, to more innovative ones like meditation and general system theory, and just maybe we should be open to the idea that the right amount of the right drugs can help.

Fossil fuels just might be on their way out, as alternatives start to become economical and public outrage slowly, almost imperceptibly continues to build.

There is real progress in the fight against disease, which alleviates enormous quantities of human suffering. I mention AIDS, diabetes, and Alzheimer’s disease above. We can be happy about that, of course. There are ideas about how to grow more food, which is going to be necessary to avoid enormous quantities of human suffering. Lest anyone think otherwise, my position is that we desperately need to reduce our ecological footprint, but human life is precious and nobody deserves to suffer illness or hunger.

Good street design that lets people get around using mostly their own muscle power. It might not be sexy, but it is one of the keys to physical and mental health, clean air and water, biodiversity, social and economic vibrancy in our cities. Come to think of it, I take that back, it can be sexy if done well.

Good street design and general systems theory – proof that solutions exist and we just don’t recognize or make use of them. Here’s where I want to insert a positive sentence about how 2019 is the year this all changes for the better. Well, sorry, you’ll have to find someone less cynical than me, and/or with much better powers of communication and persuasion than me to get the ball rolling. On the off chance I have persuaded you, and you have communication and/or persuasion super powers, let me know.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

Whatever else happens, technology and accumulation of human knowledge in general march on, of course. Computer, robotics, and surveillence technology march on. The human move into space is much slower and painful than many would have predicted half a century ago, and yet it is proceeding.

I’ll never drop the waterless sanitation thing, no matter how much others make fun of me. It’s going to happen, eventually. I don’t know whether we will colonize Mars or stop defecating in our water supply first, but both will happen.

The gene drive thing is really wild the more I think about it. This means we now have the ability to identify a species or group of species we don’t want to exist, then cause it not to exist in relatively short order. This seems like it could be terrifying in the wrong hands, doesn’t it? I’m not even sure I buy into the idea that rats and mosquitoes have no positive ecological functions at all. Aren’t there bats and birds that rely on mosquitoes as a food source? Okay, I’m really not sure what redeeming features rats have, although I did read a few years ago that in a serious food crunch farming rats would be a much more efficient way of turning very marginal materials into edible protein than chicken.

The universe in a bottle thing is mind blowing if you spend too much time thinking about it. It could just be bottles all the way down. It’s best not to spend too much time thinking about it.

That’s it, Happy 2019!

October 2018 in Review

Most frightening stories:

  • The Trump administration has slashed funding to help the U.S. prepare for the next pandemic.
  • I read more gloomy expert opinions on the stability and resilience of the global financial system.
  • A new depressing IPCC report came out. Basically, implementing the Paris agreement is too little, too late, and we are not even implementing it. There is at least some movement towards a carbon tax in the U.S. – a hopeful development, except that oil companies are in favor of it which makes it suspicious. There is a carbon tax initiative on the ballot in Washington State this November that the oil companies appear to be terrified of, so comparing the two could be instructive, and the industry strategy may be to get a weaker law at the federal level as protection against a patchwork of tough laws at the state and local levels.

Most hopeful stories:

  • There is no evidence that kids in U.S. private schools do any better than kids in U.S. public schools, once you control for family income. (Okay – I admit I put this in the hopeful column because I have kids in public school.)
  • Regenerative agriculture is an idea to sequester carbon by restoring soil and  protecting biodiversity on a global scale.
  • Applying nitrogen fixing bacteria to plants that do not naturally have them may be a viable way to reduce nitrogen fertilizer use and water pollution.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

  • New tech roundup: Artificial spider silk is an alternative to carbon fiber. Certain types of science, like drug and DNA experiments, can be largely automated. A “quantum internet” could mean essentially unbreakable encryption.
  • Modern monetary theory suggests governments might be able to print (okay, “create”) and spend a lot more money without serious repercussions. What I find odd about these discussions is they focus almost entirely on inflation and currency exchange values, while barely acknowledging that money has some relationship actual physical constraints. To me, it has always seemed that one function of the financial system is to start flashing warning lights and make us face the realities of how much we can do before we are all actually starving and freezing in the dark. It could be that we are in the midst of a long, slow slide in our ability to improve our physical quality of life, but instead of that manifesting itself as a long slow slide, it comes as a series of random shocks where one gets a little harder to recover from.
  • I read some interesting ideas on fair and unfair inequality. Conservative politicians encourage people not to make a distinction between alleviating poverty and the idea of making everybody equal. These are not the same thing at all because living just above the poverty line is no picnic and is not the same thing as being average. There is a strong moral case to be made that nobody “deserves” to live in poverty even if they have made some mistakes. And simply “creating jobs” in high-poverty areas sounds like a nice conservative alternative to handouts, except that there isn’t much evidence that it works.

September 2018 in Review

Most frightening stories:

Most hopeful stories:

  • The Suzuki and Kodaly methods are two ways of teaching music to young children that may actually help them think later in life. Training in jazz improvisation may also be good for young brains in a slightly different way.
  • There are some bright ideas for trying to improve construction productivity, which has languished for decades. Most involve some form of offsite fabrication.
  • In energy news, there’s a big idea to produce half the world’s electricity from sunlight in the Sahara desert. Another idea for collecting solar energy in otherwise (ecologically) wasted space is solar roadways, and there are a few prototypes around the world but this doesn’t seem to be a magic bullet so far. Another big idea is long-term storage of energy to smooth out fluctuations in supply and demand over months or even years.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

do kids do better in private school than public?

The answer, at least in this study, is a clear no. Kids in private school are doing better than kids in public school, but it can be entirely explained by family income.

Does Attendance in Private Schools Predict Student Outcomes at Age 15? Evidence From a Longitudinal Study

By tracking longitudinally a sample of American children (n = 1,097), this study examined the extent to which enrollment in private schools between kindergarten and ninth grade was related to students’ academic, social, psychological, and attainment outcomes at age 15. Results from this investigation revealed that in unadjusted models, children with a history of enrollment in private schools performed better on nearly all outcomes assessed in adolescence. However, by simply controlling for the sociodemographic characteristics that selected children and families into these schools, all of the advantages of private school education were eliminated. There was also no evidence to suggest that low-income children or children enrolled in urban schools benefited more from private school enrollment.

this is your brain on music, but the kind matters

Here’s an interesting article on how jazz and classical music wire your brain differently.

Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences studied the brains of thirty pianists—half jazz players, half classical. They found, the Institute reports, that “different processes occur in jazz and classical pianists’ brains, even when performing the same piece…”

While jazz improvisation may better teach creativity, classical training, as neuroscientist Ardon Shorr argues in his TEDx talk above, may better train the brain in information processing. These studies show that the effect of music on the brain cannot be studied without regard for the differing neurological demands of different kinds of music, just as the study of language processing cannot be limited to just one language.

As a classically trained musician (okay, an out of practice, amateur one at best but I did put significant time and effort into it in my youth), I can vouch for taking a jazz improv class once and being completely out of my depth. But the other students were all jazz musicians and nobody was really interested in bringing me along as a beginner. I also took a class once called “far out improv” with other classical musicians and a teacher who was specifically interested in teaching classical musicians to improvise, and I remember that being very cool. I’ve never heard or experienced anything like that since so it must have been unusual.
