Demolition on Harrington Street

Demolition on Harrington Street

This week I wrote my annual checks to my favorite charities. Giving seemed more than usually important this year, since some of my favored causes are directly threatened by the recently elected executive — the environment, human rights, civil liberties, animal rights, family planning, and those less fortunate. I felt really lucky to be able to help, even if only a little, by giving to effective organizations.

I was especially mindful of the dire plight of refugees from the Middle East, Africa, Central America, and elsewhere, and so want to mention for your consideration the work of the International Rescue Committee and Doctors Without Borders. I’ll also note that in these tumultuous times we need more than ever the wisdom and beauty of the arts, and hope others will join me in supporting the wonderful North Carolina Ballet and North Carolina Opera.

On Tuesday, Sally and I saw Allegiance, a movie of a show recently on Broadway about the experience of Japanese-Americans in WWII. It was inspired by experiences of George Takei (Star Trek), whose family, along with many others, was held in a grim internment camp. At one level, it was a normal Broadway show, with pretty songs and kinetic dances, which were enjoyable if not especially original. But it was ambitious in taking on a big and tragic subject and expressing some of its complexity. While the so-called alt right has found new methods for inspiring fear and hatred of minorities, Allegiance does the opposite — it inspires caring.

The movie of Allegiance was a one-time-only, nationwide event that I learned about from the Stuff You Missed in History Class podcast, which I’ve been listening to at the gym. Stuff You Missed often take on subjects that our American history textbooks played down or left out, because they don’t fit comfortably into a triumphalist national narrative. For example, recent ones I’ve liked have treated the Dakota War of 1862, George Wallace, the Reynolds pamphlet of Alexander Hamilton, the first transatlantic cable, and the Palmer raids. They segments are lively and have a nice balance between serious academic history and the personal, emotional implications of some dire events. The hosts, Tracey V. Wilson and Holly Frey are starting to feel like friends — really smart, curious, and hardworking, with a sense of humor. You can check it out here.

THe spirit of curiosity and engagement with new things has been upon me, and so I finished reading, and started re-reading, I Contain Multitudes: The Microbes Within Us and a Grander View of Life, by Ed Yong. It’s a lively and convincing view of the bacteria that live in us, on us, and all around us. This is a really exciting area of science, and developing fast. I like that Yong’s title used a line from Walt Whitmans’ Leaves of Grass, which also can change how we see ourselves.

When I was a child, I was taught that “germs” were bad, and the best thing to do was avoid them or eliminate them. As Yong makes clear, this was both silly and dangerous. Our bodies contain more bacterial cells than human cells, which calls into question who really owns those bodies. There are some 39 trillion bacterial cells in and on us, and thousands of species, though the particular kinds in each of us varies greatly, and the varieties are constantly changing. They are vital to our well-being. Without them, we could not grow or thrive. Each one of us is an ecosystems — microbiomes, as they now say. Without those multitudes, we could not grow, and could not continue to live. They are vital, for example, for digesting food, producing vitamins, breaking down toxins, and killing more dangerous microbes. DCIM100MEDIADJI_0017.JPG

I also finished reading On Looking: Eleven Walks with Expert Eyes, by Alexandra Horowitz. Horowitz, who teaches psychology and animal behavior at Barnard, writes well about who she sees, hears, smells, and touches in walking around New York. After an initial walk by herself considering how much there was to see in a city walk, she also realized how little she normally perceives. She does the other 9 walks with experts in some aspect of the urban environment, like a geologist, a paleontologist, an architect, a wild animal expert, a sound designer, and her dog (an expert in smells). She gives short by credible accounts of the relevant science, and makes us consider the urban environment as full of non-human life and history.

The demolition photographs here are from just down the block on Harrington Street, where they just knocked down a former furniture store that sat next to the old Board of Elections Building. They didn’t fence off the site, so I was able to take a good look around on Saturday. I look forward to more new construction in the neighborhood, including (can’t wait for this one) a grocery store.

Finally, this weekend I added a new line to the c.v.: quadcopter pilot! I took my first flight with my new DJI Phantom 4 quadcopter, a/k/a drone (a term I don’t really like, at least as applied to my aircraft) at Fletcher Park, where it was cold and gray. It was awesome! There is a learning curve, and I’m climbing it. I’m very excited about exploring aerial photography. These ones are my beginnings.

Tree behavior, Hitler, conspiracy theories, and the truth about Hillary’s email

Big Woods Road, near Jordan Lake in Chatham County, November 5, 2016

Big Woods Road, near Jordan Lake in Chatham County, November 5, 2016

Saturday morning was brisk, sunny, and clear. I drove Clara out to Jordan Lake, where I put her in sport mode and enjoyed the winding country roads. We drove up one of my favorites, Big Woods Road, and stopped at various spots to look for birds and colorful trees.

I’ve been reading The Hidden Life of Trees: What They Feel, How They Communicate, by Peter Wohlleben. Wolleben has spent his life as a forester closely observing trees, and has also assimilated a great deal of research into their biology and behavior. As the title indicates, he contends that trees are social plants that cooperate with sophisticated systems for communication, including underground connections of roots and fungi and various airborne chemicals. They work together to ward off predators, withstand weather, and take care of the young. It’s amazing! There’s a nice overview of the book at Maria Popova’s wonderful blog, Brainpickings.

On a more somber note, I’ve been reading the new biography of Hitler by Ullrich Volker. It covers H’s birth to the start of WWII. It’s a good read, and offers insights into (though no definitive solution to) the great mystery: how could an intellectually mediocre charlatan maniac seize and hold dictatorial power, with such dire consequences? At the end of WWI, Hitler quickly rose in political life as a popular speaker on the theme that there was a vast, powerful Jewish conspiracy that accounted for Germany’s problems.

This bizarre conspiracy theory was widespread at the time, and of course has never disappeared. How do such crazy ideas take root and propagate? There seem to be a lot of them flying around these days. A case in point: militiamen who believe the Second Amendment is under siege. The NY Times had a fascinating piece yesterday on these folks by David Zucchino, with good pics by Kevin Lyles.

They are mostly white, rural, and working class, and they like to get together on weekends to shoot their weapons. Zucchino got them to talk. They are passionately convinced of many nutty ideas: Hillary is coming to get their guns, ISIS is invading the country, the Democrats are rigging voting machines. Also, they want to make America great again. All I can say is, Yikes!

Only slightly less bizarre is the meme, now rampant, that Hillary’s email handling shows that she is unusually dishonest and corrupt. Matthew Yglesias of Vox did a good piece unpacking this tale and showing it to be based on nothing. Hillary’s handling of email was not illegal, and there’s no basis for accusing her of dishonesty. And yet the networks have devoted more air time to this non-story than every other policy issue combined.

Yglesias concludes as follows:

One malign result of obsessive email coverage is that the public is left totally unaware of the policy stakes in the election. Another is that the constant vague recitations of the phrase ‘‘Clinton email scandal’’ have firmly implanted the notion that there is something scandalous about anything involving Hillary Clinton and email, including her campaign manager getting hacked or the revelation that one of her aides sometimes checked mail on her husband’s computer.

But none of this is true. Clinton broke no laws according to the FBI itself. Her setup gave her no power to evade federal transparency laws beyond what anyone who has a personal email account of any kind has. Her stated explanation for her conduct is entirely believable, fits the facts perfectly, and is entirely plausible to anyone who doesn’t simply start with the assumption that she’s guilty of something.

P.S. On Monday morning at the gym I listened to the podcast version of the latest This American Life, which included a segment on Hillary and the emails. Garrett Graff, a veteran reporter, came to pretty much the same conclusion as Yglesias: there’s no actual scandal. Graff noted that he, like other reporters, always hopes investigations will lead to titillating revelations of misconduct. We often see what we want to see, whether it’s there or not, which may account for some of the press’s egregiously biased “scandal” reporting of the email story. Those reports started a feedback loop that has grown very loud and shrill and overwhelmed our ability to consider the facts.

Wildflowers, bug bites, and why I’m getting behind Hillary

Wrightsville divingBug 1-2It’s been unpleasantly hot and humid this week. On Saturday I got out early to avoid some of the heat and visited the park at the art museum and hiked in Schenk Forest. I enjoyed seeing and photographing the wildflowers and butterflies.

Taking this kind of pictures involves getting heading into the woods and pushing through the high grass. On Saturday I was still recovering from fifteen or so bug bites on my legs from an outing at Jordan Lake two weeks ago. These were no ordinary mosquito bites. They were much bigger, itchier, and longer lasting. Some of them were probably chiggers, but I have no idea what creatures did the others. I also had a couple of tick bites.

There is a real risk of Lyme disease and other insect-borne illnesses in these parts, and I’ve made up my mind to take more care. No more wearing shorts on these kinds of outings, and more systematic insecticiding. I tried out Avon Skin-So-Soft Bug Guard Plus, which includes SPF 30 sunscreen. I got no new bites, though of course it’s possible the biting bugs were busy elsewhere.

There’s an interesting recent essay by Jonathan Haidt, author of The Righteous Mind, explaining the rising tide of anti-immigrant paranoia in terms of the psychology of authoritarianism. Authoritarians, defined according to child-rearing preferences like prioritizing obedience, are in Haidt’s view not naturally intolerant, but become more so when they perceive a threat to their values and culture.

For example, Muslims who insist on their own distinctive customs pose an implicit challenge to traditional mainstream customs and values, and the authoritarian personality reacts with alarm and anger. This alarm isn’t so much fear of mass killings as of dilution of the values that bind together families and communities. Liberals don’t understand or sympathize with those feelings, but right wing demagogues understand and exploit them.

It’s an interesting theory, and seems to explain some of the weirdness now in the air. Even if not completely right, it reminds us how complicated and varied humans are, and how little we really understand about the drivers of our behavior as either individuals or groups. More study is needed, as the scholars say.
Wrightsville divingBug 1-9

Anyhow, many Democrats, including me, can affirm that perceived threats can draw us together. So it was this week that many of us, disturbed and mildly traumatized by the anger and barely repressed violence of the Republican Convention, decided it was time to put aside our differences and pull for Hillary. Whatever else, she is the lessor of the evils, by at least an order of magnitude.

I truly respect and admire Hillary Clinton for her intelligence, strength, and discipline, and her long record of public service. At the same time, I worry that her natural instincts will dispose her to continue the status quo of wide income inequality and destructive militarism. But there’s a possibility she can change. And there is no imaginable scenario in which she is the author of the kind of disasters and self-inflicted wounds surely in store under President Trump. We need to work together for a massive Hillary victory that leaves no question that the great majority of us completely reject him and his ideas.

Duke blossoms, rising ballerinas, AlphaGo’s victory, and the Age of Artificial Intelligence

Tiller7Bug 1-6
On Saturday morning it was overcast and threatening to rain when I drove over to Durham to see what was blooming at Duke Gardens. Did you know it’s one of the top 10 public gardens in the U.S.? It is certainly a treasure. There were new cherry blossoms, tulips, and many other delights. I shot 234 closeup images with my Nikkor 105 MM macro lens before it began to drizzle. I got a few that revealed aspects I’d never looked at as closely before, and expressed some of my own joy of the season. The images here are all from Duke, except for the daffodils, which I took late Friday afternoon at Fletcher Park.

That evening we saw the Carolina Ballet with new works by Zalman Raffael and Robert Weiss. Raffael’s new piece was set to Rachmaninoff’s Rhapsody on a Theme by Paganini. As it launched, I worried a little that 24 variations to this familiar music could easily bog down, but far from it: this was a lively, kinetic work that developed organically with continual surprises. Working in the Balanchine tradition, like Weiss, Raffael makes ballets that are abstract but intensely expressive. He’s so accomplished and assured already, and so young!

In the performance we saw, some of the younger company members who normally are in the background stepped into the spotlight, and performed beautifully. I very much enjoyed the subtle elegance of Courtney Schenberger and Rammaru Shindo in Balanchine’s Valse Fantaisie. Ashley Hathaway, with Adam Crawford Chavis, was really sensual and powerful in the adagio Meditation from Thais. Amanda Babayan was a lovely Miranda in Weiss’s Tempest Fantasy. So much talent, developing quickly, like those blossoms. It’s a privilege to receive their art.

Speaking of surprising progress, this week AlphaGo finished its five game Go match with a popular Korean grandmaster in Seoul, in which it prevailed 4-1. It was a significant moment in the advance of artificial intelligence. I learned the rudiments of Go a few years back. It seems so simple at the very beginning, as you take turns laying single stones, black or while. But it is massively more complex than chess. There are more possible moves than there are atoms in the universe.

Anyhow, I tweeted congratulations to the Google team, though with mixed feelings. The Age of AI is on its way, and the prospects are both good and bad. Computers are mastering tasks that we thought impossible for them a few years ago, like driving, reading MRIs, and reviewing legal documents. In the new Age of AI, there will be safer cars, more reliable medical care, and cheaper legal services. On the down side, a lot of jobs are going to disappear forever. We’re going to need to figure out what to do about having a lot of redundant humans. We’ll probably need to come up with a system with a guaranteed minimum wage, which seems impossible at present from a political perspective.
Tiller7Bug 1-2

But maybe the AI on the way can help with some of our political and mental problems. I’m thinking particularly of our magical thinking – areas where our biases and received ideas prevent us from seeing what’s right in front of us. The drug war is an example. After several decades of being taught that particular plants and chemicals are inherently evil and threatening, and that we need to fight those drugs, we have trouble conceiving of any alternative. It makes no difference that the drug war never moves any closer to victory, and that the human collateral damage is enormous. The facts that do not fit with our long held beliefs are suppressed or ignored.

Climate change denialism is another example of magical thinking. Another one: the Republican mainstream belief that cutting taxes will lead to increased growth, higher tax revenues, and balanced budgets. The New Yorker had a good essay by James Surowiecki this week explaining that decades of evidence now show that, as you might initially expect, cutting taxes leads to lower tax revenue. But current Republican leaders and followers, like those before them, devoutly and streadfastly deny the obvious.

The WSJ had a must-read essay this week by David Gelernter on AI. Gelernter, a professor of computer science at Yale, argues that the intelligence of our machines will inevitably surpass our own, and we cannot reliably predict what will happen after that. Thinks of machines with IQs of 500, or 5000. They could be dangerous, perhaps viewing us as we view houseplants. Gelernter suggests that in experimenting we exercise the kind of caution we use with biological weapons.

But hey, assuming that the machines do not decide to enslave or kill us, they could really be helpful. They would almost surely see more possible moves in addressing difficult problems, like global warming. Perhaps it would be so obvious that they’re reliable authorities that we would give up on magical thinking. Then again, such thinking is almost perfectly hermetic and impervious.

A sliver of hope

Raleigh 3
We had some weird weather in Raleigh this week, including hail, intense winds, and tornado warnings. I was in a meeting on the 18th floor of Red Hat Tower when everyone’s smart phone gave a warning signal, and we agreed it was time to get away from the windows. We took our computers to a big interior closet, where we continued the meeting. The building was still intact when we emerged.

Was it global warming? Hard to say. Good scientists are by training careful and conservative, and usually avoid ascribing root causes to particular weather events. But we know for sure the globe is warming, and the problem is big. Make that existential.

This is not an easy subject to think about. First, it’s depressing: the long-term risks for humans, other animals, and other living things are grave. Also, it’s uncomfortable: in trying to understand the problem, we ultimately end up seeing part of it in the mirror. All of us who like having electricity and traveling with internal combustion or jet engines are complicit. Also, there isn’t a clear path to a solution with our existing dysfunctional institutions.

But there’s still a sliver of hope, which I try to keep in mind. Helpful on this is Al Gore’s new TED talk. He doesn’t pull any punches in describing the destruction humans have wreaked on the planet with greenhouse gas emissions, but he also notes that we’ve made tremendous progress in wind and solar power, and progress is continuing. We may turn this around. Anyhow, it’s encouraging that he hasn’t thrown in the towel.

In reading a Times report this week about rising sea levels and increases in coastal flooding, I clicked on this link
which is a great little primer on global warming. It’s organized in a FAQ format, with short form answers to questions like how much is the planet heating up, how much trouble are we in, and is there anything we can do. It takes just a few minutes to get the basic facts. And armed with those, there are some things we can do, like elect leaders who have a clue.

On the climate hope front, I also need to give a shout out to Bill Gates, whom I have not always viewed as a force for freedom and progress. Gates may ultimately do far more good for the world as a promoter of emissions reduction technology than he has done as a software technologist. Anyhow, he’s got up on his bully pulpit, and he’s clearly working hard to encourage innovative energy ideas.

My recent reading and listening

Tiller7Bug 1-5
One thing that I hate about vacations is that I always come back heavier than I went out. It’s strange, but predictable, that a week of traveling makes me about five pounds heavier. There’s nothing particularly terrible about gaining five, but if you do it enough times, it adds up. I really prefer not to carry around excess pounds, which means, post vacation, I’ve got some reducing to do.

That requires some time exercising, which, fortunately, I enjoy, in a way. It’s a lot more enjoyable since I started combining working out with listening to podcasts and audio books. This week at the gym I’ve been listening to the new Serial, about Sergeant Bowe Bergdahl, which examines the mystery of what he was really up to when he was kidnapped by the Taliban. It’s good. I also discovered WTF, an interview podcast by Marc Maron, and listened to an interview with Eric Bogosian, the actor, playwright, and author. He was a student at Oberlin when I was there. Among other impressive talents, he has an amazing voice.

Speaking of talented people I knew slightly, I saw articles in both the NYT and WSJ this week about the artist Robert Irwin. I met Irwin when I was a fact checker at the New Yorker and checked a piece about him by Lawrence (Ren) Weschler that became a book, Seeing is Forgetting the Name of the Thing One Sees, which is still in print.

I really liked Irwin, and was affected by his vision. His work is difficult to describe, but generally involves transforming spaces so that they reveal different things. He has spent most of a restless career, based in Los Angeles and then San Diego, creating subtle, at times vanishingly evanescent, environments with plain materials — fabric scrim, glass, lights, plants and trees — “to make you a little more aware than you were the day before,” as he puts it, “of how beautiful the world is.” He’s now 87, and has various interesting works in progress. Anyhow, I recommend Ren’s book, and the articles, and I’m planning to try to get io his new show at the Hirshhorn.
Tiller7Bug 1-4

One thing I like about vacations is some time to really read. Last week I finished a couple of significant books and made substantial progress in others.

I finished Don’t Panic: ISIS, Terror and Today’s Middle East, by Gwynne Dyer. It helped me get a better grip on the geopolitics that led to ISIS, and that sustain the violence going on right now. The atrocities of ISIS are horrifying, but per Dyer we really have to quit freaking out, because it doesn’t help, and they are not an existential threat to us.

Which is not to say they aren’t wreaking havoc on the Middle East. The plight of millions of Syrian and other refugees is horrendous, and winter is just well started. I did a bit of research of what we as individuals might do to help, and ended up making a contribution to the International Rescue Committee. The Times endorsed it and some other charitable organizations. Please consider whether you might be able to help.

I also finished Black Earth, the Holocaust as History and Warning, by Timothy Snyder. The subject of Hitler’s genocide is, of course, tough to think about, but it turns out that there are very important aspects of it that our history professors and museums mostly missed until – Snyder. For example, most of the Jews killed in the Holocaust were victims of mass shootings, rather than gassing, and the likelihood of dying varied according to the degree to which the existing state apparatus was destroyed, as it was in Poland and the Baltic states. As depressing as it is that humans can be as depraved as the Nazis, it is also cheering that we can understand the past in new ways, and maybe change ourselves.

I made substantial progress on re-reading Your Atomic Self: The Invisible Elements that Connect You to Everything Else in the Universe, by Curt Stager. Stager does a good job showing how atoms relate to life as we know it, which is both well known and very difficult to grasp. He breaks the world down to its essentials, starting with hydrogen, oxygen, carbon, and nitrogen, and shows how basic recycled elements form our bodies. I’ve finally got firmly in mind how a lot of the atoms we are made of are the products of long-dead stars. Joni Mitchell was right that we are stardust. And, just as we are continually transforming our surrounding environment, it is transforming us.

A new colleague at work, Jeff K, recommended I read Hackers, by Steven Levy. It’s a history of the computer programming pioneers of the sixties and seventies at MIT, Silicon Valley, and elsewhere. I quickly got absorbed, and have made it about halfway through so far. These people were obsessed, and in some cases brilliant, as they discovered/created the new digital world that we live in today. A lot of them were awkward and odd, and did not have normal social lives (e.g. girlfriends). I thought that seemed sad, but gradually realized how full they were of the joy of discovery. A lot of these pathfinders were making free and open source software well before anyone labelled it as such.Tiller7Bug 1-2

Finally, I made substantial progress on The Goldfinch, by Donna Tartt. I was interested in the book initially because I love Dutch painting of the 17th Century, and I’ve seen Fabritius’s famous, gorgeous Goldfinch. I’m finding Tart’s book extraordinary, in the way Catcher in the Rye is extraordinary, with perceptions that have the freshness of youth and the risk of fatal error of youth. She’s a great novelist in the old-fashioned way, with a deft grasp of quick emotions and richness of character and incident.

While I’m thinking of brilliant artists, I’ll mention one more recent discovery: the violinist Sarah Chang. As I now know, she was a child prodigy and is now a seasoned concert artist, but I discovered her a few weeks back by chance when I felt like listening to the Brahms violin concerto, and picked her recording from those available for streaming on Rhapsody. (The same recording is available on YouTube) She’s amazing! Volcanic intensity, and yet sensitive to the finest nuance. She’s got a big, gleaming, shimmering sound. Here she is in a wonderful live performance of the Carmen Fantasy.

Saturday I drove out to Cary for my haircut with Ann S, and got caught up on her holiday doings. Afterwards I drove east to Chatham County and visited Jordan Lake. It was gray and raw, with rain threatening, and the water level was high. There were hundreds of gulls at Ebenezer Point, mostly ring-bills and a few herrings.

Older athletes, my 5K race, working out with audio books, CRISPR, and Uber

IMG_4297
I like stories of successful athletes who have passed the normal age for athletic achievement, for obvious reasons. There was a good one this week in the WSJ, which featured Klaus Obermayer, founder of an outdoor clothing company. At 95, he lives in Aspen, skis whenever there’s snow, does Akido, and swims, along with getting gym workouts, and eats a mostly vegan diet. I’ve previously challenged myself to still be skiing the big mountains at 85, but it looks like I may need to raise the bar.

On Saturday morning I ran a 5K race in downtown Raleigh – the Jingle Bell Run, a charity event for the Arthritis Foundation. It was a beautiful fall day, clear and chilly, and a lot of my Red Hat colleagues showed up at Saint Mary’s School. Jonathan C, an accomplished runner, let me tag along as he did his warm up routine. Sally came along with Stuart and lent moral support.

The route was up and back on Hillsborough Street, which is a long climb going out, but it went OK. On the home stretch, as I passed the International House of Pancakes, I had a shot of pain in my left hamstring, and struggled to the finish. But I still ended up with an official time of 25:12. That’s average miles of 8:10, which was close to my planned best case scenario. Jonathan came in third, at 18:02 (5:49/mile). Sally said Stuart had a nice time: lots of people petted him, and asked his name and how old he was (13).

At the gym lately, I’ve been dividing my time among the various cardio machines – treadmill, elliptical, stationary bike, rowing, and stairs – putting in about 45 minutes of total sweat time, plus core work, resistance training, and stretching. Listening to audiobooks and podcasts makes this a lot more fun. This week I discovered News in Slow Spanish, which is exactly what it sounds like – a podcast for intermediate Spanish learners who like to listen to the news. My comprehension went way up when the announcers slowed way down.

I’ve also been listening to Redefining Reality: The Intellectual Implications of Modern Science, by Steven Gimbel. Gimbel has really helped me with the last 100 years of physics. I’m not prepared to claim deep understanding, but I’m getting more comfortable with, for example, the idea of gravity as a bend in space-time, and matter as just an expression of energy.

We like magazines, but it’s hard to keep up with them. In the last couple of weekends I made good progress in dealing with the pile of New Yorkers, Economists, Atlantics, Opera Newses, and Scientific Americans (but didn’t get to the pile of golfing, photography, and scuba magazines). I finally got a fix on what CRISPR is from a New Yorker piece by Michael Specter, and realized this is a technology that is going to change the world as we know it. The CRISPR tools allow biologists to edit DNA relatively simply and cheaply. This holds the potential for understanding and treating various serious diseases, and also improving food and industrial products. And, of course, there’s the possibility of creating Frankenstein monsters. Anyhow, for better or worse, or both, the genie is out of the bottle.

Last week came the end of driving as we know it – the beginning, for us, of the age of Uber. We scheduled a trip to our old favorite, Caffe Luna, and with a view to avoiding post-wine driving, I downloaded the Uber app. Our first experience was entirely friction free – no telephone call, no waiting, no tipping, and automatic payment, at an entirely reasonable rate. We gave our drivers high ratings, and hoped they did the same for us. I’ve been tracking the progress of driverless cars closely, but had sort of ignored Uber. Now I get it – it’s fantastic.

A photo contest, getting shoulder therapy, trying fasting, and not debating climate change

Rob Tiller -- Passionate Embrace -- 2015 (1 of 1)
Sally spotted a notice in the local paper of a nature photography contest at Raulston Arboretum. The theme was gardens and plants, which you may have noticed I have an interest in, and so I decided I might as well have a go.

Competition is a good way to make yourself try a little harder. With the thought of critical judging, I took a careful look through some of my favorite images, and found little disqualifying problems on most of them. Of those still left, some just didn’t touch me. That exercise alone was worthwhile, good for my eye and mind, win or lose. Ultimately, I settled on the two bees shown here, worked on them for a bit with Lightroom software, and got them printed on metallic paper nearby at JW Image. Still to do: getting them framed, submitted, back, and hung in the apartment.

Speaking of self-improvement, I finally decided this week to get physical therapy help for my left shoulder. I’d tried letting the thing heal itself with several weeks of relative rest (no heavy weight lifting), but that didn’t work. I got in to see Geert Audiens at Results Physiotherapy, who’d helped me with back and shoulder issues before. Geert quickly diagnosed a torn rotator cuff, which, he said, would get worse if not attended to. He predicted it would take several weeks of specialized exercises, but it would likely get better. It’s good to have well-functioning arms and shoulders. And so we began, with simple little exercises, antiinflammatories, and icing four times a day. It’s a substantial commitment, which I hope will be worth it.

I’ve also been experimenting for a few weeks with a modification of my food consumption. I’d somehow picked up 5 pounds that would not come off, even with hard cardio work outs and careful healthy eating. I saw a story on alternate day fasting for the weight control, which basically means eating very lightly (500 calories) every other day. I decided to have a go for two days a week, a variation which, I just learned by googling, has been promoted elsewhere by others.

My method was my normal greens-and-fruit smoothie for breakfast, salad for lunch, and nothing for dinner. The no eating intervals were challenging, especially at dinner time with Sally eating. But it helped clear the mind, and made me more conscious of eating well on the normal eating days. And I did get rid of those 5 pounds in about 3 weeks.

The debate of the Republican presidential contenders this week promised to be rich with irony and ridiculousness, with the numerous conventional candidates facing off with the loutish Donald Trump. As a Democrat, I’d never looked forward to a Republican debate so much. There were, as it happened, no meltdowns. In fact, I was surprised at how articulate and intelligent most of the field seemed (with the Donald as usual the big exception).

Yet collectively they have such enormous blind spots. It’s difficult to see how you could propose to govern or even talk seriously about social policy without quickly getting to the issue of what to do about CO2-caused global warming and the many related problems, like rising oceans, mass extinctions, famine, resource-related wars, mass population dislocations, destructive storms, drought, etc. These related disasters are front page news now. Yet this issue doesn’t appear on the Republican agenda, except for opposing whatever action the President proposes. This is wildly irresponsible. The situation is dire, and getting worse.

Rolling Stone published a good piece featuring new climate change research by James Hansen and others, which I recommend. It isn’t easy to think about this problem, which makes us uncomfortable and unhappy, but we’ve got to do it. I was glad to see that Hansen thinks a carbon tax could potentially pull us out of our present suicidal course. Anyhow, we all need to get more educated on this, and to keep pressing our politicians for action.

Pope Francis’s vision

It’s been ungodly hot in Raleigh this week, with a record high of Fahrenheit 99 on Tuesday. Humid, too. So instead of running on Saturday, I settled in to read some of Pope Francis’s new encyclical, Laudito Si. From newspaper reports, I’d expected a sort of primer on the perils of global warming, but it turned out to be much more than that, and I felt enriched and inspired by the experience. It’s available online here.

Even though I’m a thorough-going non-believer, I’m a big fan of Francis. He seems to be a genuinely warm, caring, and thoughtful person. What are the odds? How daunting and disorienting to be considered by many as infallible, and fully realize you aren’t. (Remember his famous words,“Who am I to judge?”) How dissonant to live amid Vatican magnificence and rock-star adulation and try to focus on the problems of the poor. And who would volunteer to be in charge of cleaning up pedophile priest networks, bishop cover ups, money laundering holy bankers, and God knows what other crimes and misdemeanors? And after all that, who would have the courage and drive to speak truths that implicitly threaten the world’s wealthiest, most powerful interests on what are, for them, as well as us, issues of existential importance? That’s right: my man Francis.

I was hoping that Laudito Si would have an executive summary, but it does not. Still, I kept reading. The prose is lucid and emphatic, with an animating passion. Francis leaves no doubt that he agrees with the scientific consensus that man-made greenhouse gases like carbon dioxide are responsible for much of the global warming crisis. He states that there is an urgent need to reduce such emissions and develop renewable energy. If he accomplished nothing more than calling more attention to this issue and inspiring high level discussion and action, that would be a lot. But Laudito Si does more than that, persuasively articulating a powerful ethical vision that calls for reforming both societies and our selves.

Francis calls on the people of the world to recognize that we are in an ecological crisis, and need to expand our dialog and work together to address this crisis. The dimensions of the crisis include air and water pollution, fresh water shortages, rising oceans that threaten large cities, and increasing extreme weather events. Not to mention the extinction of many species. He states, “Each year sees the disappearance of thousands of plant and animal species which we will never know, which our children will never see, because they have been lost forever. The great majority become extinct for reasons related to human activity. Because of us, thousands of species will no longer give glory to God by their very existence, nor convey their message to us. We have no such right.”

At the same time, Francis reminds us of the vibrant beauty of the natural world. He has sections on rainforests and other wonders. On a topic particularly close to my heart, he writes of “the immense variety of living creatures” in our oceans which are threatened by uncontrolled fishing and the coral reefs that have been harmed by pollution and rising temperatures.

Early on, Francis rejects the reading of the Bible that entitles humans to dominate and exploit all earthly resources. He writes instead that humans are meant to be careful stewards of those resources, and regard them with awe and wonder, and recognize our essential connection to animals, vegetables, and minerals. “Because all creatures are connected, each must be cherished with love and respect, for all of us as living creatures are dependent on one another.” He returns a number of times to the theme of our interconnectedness to each other and the world.

An aspect of this theme is concern for both the poor and for other living creatures. He writes, “We should be particularly indignant at the enormous inequalities in our midst, whereby we continue to tolerate some considering themselves more worthy than others. We fail to see that some are mired in desperate and degrading poverty, with no way out, while others have not the faintest idea of what to do with their possessions, vainly showing off their supposed superiority and leaving behind them so much waste which, if it were the case everywhere, would destroy the planet. In practice, we continue to tolerate that some consider themselves more human than others, as if they had been born with greater rights.”

Similarly, Francis draws connections between our treatment of animals and our basic humanity. Recently I’ve been feeling indignant about the new North Carolina ag gag law, which among other things protects industrial agriculture operations from those who propose to publicize their cruelty to animals. Let me just say, this is so wrong! This excerpt is apropos: “When our hearts are authentically open to universal communion, this sense of fraternity excludes nothing and no one. It follows that our indifference or cruelty towards fellow creatures of this world sooner or later affects the treatment we mete out to other human beings. We have only one heart, and the same wretchedness which leads us to mistreat an animal will not be long in showing itself in our relationships with other people. Every act of cruelty towards any creature is ‘contrary to human dignity.’”

Part of the ambition of Laudito Si is to reset our relationship to technology. “Ecological culture cannot be reduced to a series of urgent and partial responses to the immediate problems of pollution, environmental decay and the depletion of natural resources. There needs to be a distinctive way of looking at things, a way of thinking, policies, an educational programme, a lifestyle and a spirituality which together generate resistance to the assault of the technocratic paradigm. . . . To seek only a technical remedy to each environmental problem which comes up it to separate what is in reality interconnected and to mask the true and deepest problems of the global system.” Francis envisions a world where the capitalism and technological progress are no longer allowed to drive increasing inequality and alienation, but instead are put in the service of human needs.

Of course, I don’t mean to endorse all of Francis’s views. I read the sections on God’s acts and intentions in much the spirit that I read the poetry of Milton. I think he’s quite mistaken about the value of building a market for carbon credits, which would creative incentives to reduce emissions. I also regret that he dismisses the serious risks of overpopulation, which needs to be moved way up on our list of priorities. But I’m finding the work inspiring, and hope many will read it and think about it.

Bad ski luck, good paintings, and amazing atoms

Our ski trip to Whistler was a mixed success. The alpine vistas were out-of-this-world beautiful. The runs were long, and the terrain was varied and challenging. The skies were mostly blue, and the temps were moderately cold. The village was bustling with lots of shops and restaurants, and people speaking many different languages. The free bus system got us around, though we sometimes had to wait a while. We had exciting adventures, good meals, and laughs with family and friends.

The snow, though, was disappointing. We arrived right after two exceptionally good snow years, and in the middle of what’s normally the snowiest time of year, but found it hadn’t snowed for weeks. Bad luck! There was still snow on the upper part of the mountains, but for most of our stay, its texture ranged from fairly hard to super hard.

The sound of skis on fairly hard snow is sort of like the sound of an ice scraper on an icey car windshield, or a snowplow scraping a street. We learned to listen for that sound as we went up the lifts and watched skiers descending the steeps, and pondered the least noisy way down. At speed on hard snow, you get bounced and buffeted, and you make those awful scraping sounds. You need to watch out for rocks. It’s hard to relax and let it flow.

But we did find some areas of non-punishing snow, and had a certain share of joyous turns. We particularly enjoyed some areas on Blackcomb mountain that had dramatic rolling ups and downs. There were pitches with non-icey moguls that were fun. And at the top, as I mentioned, spectacular alpine views.

I skied on rented Volkyl Kendos, which I found to be versatile and reliable, stable at speed and quick from edge to edge. I was also happy with my new Dalbello Panterra 100 boots, which were easy to get on and stayed in good communication with my edges.

We had an afternoon in Vancouver before heading home, and checked out the Vancouver Art Gallery, a fine old building in the classical style. There was a exhibition featuring some fine works of Cezanne, Degas, Pissaro, Van Gogh, Modigliani, and Soutine collected by Henry and Rose Pearlman. I enjoyed the paintings, and was particularly glad that Gabe could see this well-chosen collection, while his own artistic eye is developing so quickly.

We also checked out an exhibit of contemporary Chinese art, where I saw two pieces that blew me away: a giant sculpture by Ai Weiwei made of hundreds of antique three-legged stools (shown in this video) and installation involving ceramics by Liu Jianhua that seemed to hover both in space and time. We also stopped in the Coastal Peoples Fine Arts Gallery, which had interesting masks, totem poles, and graceful stone sculptures of bears and other creatures.

On the trip back, I finished reading Your Atomic Self: The Invisible Elements that Connect You to Everything Else in the Universe, by Curt Stager. Its main point is to explain how our bodies are built and operate from an atomic perspective. We all know, sort of, that we’re essentially atoms, but it’s challenging to grasp and accept what that really means. Stager traces our oldest bodily elements back to their origin in exploded stars, and explains how our constituent atoms have been recycled through minerals, vegetables, and animals prior to arriving in us. The idea that we’re connected to everything around us turns out to be true! I found it challenging, and inspiring.
