Beast

Spring                                                                     Maiden Moon

beast inFinished a 2010 book, The Beast in the Garden, today.  By David Baron, an NPR reporter, Beast examines the changing nature of the wildlife/human interface especially through an examination of mountain lion activity in and around Boulder, Colorado in the late 1980’s into the mid-1990’s.

Baron did an exhaustive amount of work.  He recreates the time period in which Boulder’s love for nature and its actions to both create and preserve a natural setting resulted in tragedy and conflict. After several years of encouraging wildlife into the city through tolerance, rings of urban parks and conservation of land outside its limits but contiguous, Boulder had an irruption of deer. An irruption is, as Baron says, very similar in meaning to its volcanic homonym.

There’s a saying here on Shadow Mountain, “If you have deer, you have mountain lions.” That proved true in Boulder. The problem was, that since the elimination of the wolf, mountain lions no longer had any predator of their own and had become desensitized to their ancient foe: the canid. No longer did just any dog barking drive away mountain lions. That meant the lions could follow their main food source, deer, into human inhabited areas where they could encounter dogs.

Some cougars began to hunt dogs. The combination of hunting deer, their ancient and still most frequent prey, and dogs, kept as pets and therefore nearby human’s daily life, led to certain cougars becoming habituated to humans. Habituation involves suppression of the once instinctive fear of humans engendered by early farmers and ranchers near extermination of the species. Once that fear is suppressed humans are bipedal potential sources of dinner. Dogs were eaten. Cougars lounged in people’s backyards. A few attacks occurred. Then, a couple of deaths. This book tells that story.

 

Anxiety

Palmer Hayden, a painter of the Harlem Renaissance, did a series of 12 paintings about the John Henry legend.  John Henry matched his muscle and steel-driving skill against a steam engine. When watching Alphago, the DeepMind computer program, play Go champion and legend himself, Lee Sedol, Michael Redmond, a Western go master at the 9-dan (highest level) said he really wanted to play the computer.

Here’s a quote from the only man who claimed to have seen the John Henry contest:  “When the agent for the steam drill company brought the drill here,” said Mr. Miller, “John Henry wanted to drive against it. He took a lot of pride in his work and he hated to see a machine take the work of men like him.” wiki, op cit

 

This is Lee Sedol and his daughter at Match 3. He lost, for the third game in a row, losing the match of 5 games to Alphago. Quite a different scene from Hayden’s imaging of John Henry’s loss, but still a human loss to a machine.

It occurs to me that both images evince a fundamental difference between humans and machines, love and concern for another. In Lee’s case, he and the Alphago team member are smiling, shaking hands. He has his arm around his daughter, another key distinction between  humans and machines, biological procreation. Parenting, the long task of raising a human child until they can take off on their own, is also a complex relational challenge, one well outside the current and possibly future capacity of artificial intelligence.

 

As John Henry lies dead, a heart attack brought on by the stress of the competition, others surround him. Their expressions vary from disbelief to sadness. One man has a ladle of water to offer, indicating that Henry must have just died. Too, the endurance of the legend and the song about John Henry show how deeply rooted are the questions. Is a human determined, defined by his or her capacity to defeat a machine? Ever?

Lee Sedol said, at the end of Match 3, “Lee Sedol lost. Not humankind.”

There is a fundamental anxiety about humanness revealed here. It is the question that Ray Kurzweil believes he has answered in his book, The Singularity Is Near. In Kurzweil’s mind, all of these human versus machine moments are stair steps toward the ultimate confrontation between humans and an artificial intelligence that is superior to us. The John Henry legend foreshadows what will happen. Like the steam drill a superior consciousness will simply eliminate the competition, not out of pique or malevolence, but because that is what happens when superior beings interact with inferior ones.

 

I don’t believe it. I believe the crowd around John Henry, the shaking hands at Match 3 with Alphago and the presence of Sedol’s daughter shows the true distance machines will have to travel to become superior to humans. And, when the contest is over love and compassion, the human characteristics on display in these two instances, then the machine will not want to eliminate us, but to embrace us.

Tokamak vs. the Stellarator

Friend Bill Schmidt found this follow-up to an earlier post about the stellarator. You may not recall it, but this is the next step toward a possible source of power generated by nuclear fusion. May it be successful.

Tokamak and stellarator are designs for fusion devices.

from earthlink.net.

GREIFSWALD, Germany (AP) — Scientists in Germany flipped the switch Wednesday on an experiment they hope will advance the quest for nuclear fusion, considered a clean and safe form of nuclear power.

Following nine years of construction and testing, researchers at the Max Planck Institute for Plasma Physics in Greifswald injected a tiny amount of hydrogen into a doughnut-shaped device — then zapped it with the equivalent of 6,000 microwave ovens.

The resulting super-hot gas, known as plasma, lasted just a fraction of a second before cooling down again, long enough for scientists to confidently declare the start of their experiment a success…

Although there are about a dozen stellarator experiments around the world, including in the U.S., Japan, Australia and Europe, scientists say the Greifswald device is the first to match the performance of tokamaks.

Quite an Array

Called up our solar array on Alternative Energy Systems. Each of our microinverters, one per panel, sends out a message about its panels performance. 27 panels, 27 graphics with the amount of energy in watts being produced at any one moment. Very cool. Except for the fact that we have snow on the panels and only a few are producing at near optimum. Plus, even with tree cutting we’re still getting some shading. This will take some time, maybe a full year, to assess. The good news is that electricity now comes from the sun through the photovoltaic panels and into our home. (chart from today)

Not Commendable, But True

Not commendable, but true. I’m finding the pink ribbons, glowing reports of breast cancer survivors and the breathless joy of pink clad marathoners and professional athletes annoying. No, I don’t begrudge a single woman their successful treatment. Far from it. I’m glad.

It’s just that my own crew, prostate cancer survivors, have their cancer, get treatment, then get back to their lives. I don’t see blue ribbons (the color for prostate cancer. which makes some gender stereotypical sense) on cars, athlete’s sneakers, bedecking runners in the prostate cancer marathon. No smiling men surrounded by their buddies cheering them on.

This year the National Cancer Institute estimates there will be 231,480 new cases of breast cancer diagnosed, 14% of all new cancer cases. Over the same period it estimates 220,800 new cases of prostate cancer, 13.3% of all new cancer cases. Breast cancer will cause the death of 40,290 women and a small number of men, 6.8% of all cancer deaths. Prostate cancer will account for 27,450 deaths, 4.7% of all cancer deaths.

The numbers, then, are very similar though breast cancer does occur somewhat more often and causes more deaths.

 

Still, when I saw a woman celebrating her survival of stage 1 breast cancer being feted like a celebrity, a slow wave of rancor pulsed through me. I had stage 2. This is childish, I understand that. My cancer was worse than yours and you get all the fun. Geez.

A woman I know, when I confessed this emerging feeling, said, “Well, breasts are visible, more important to a woman’s sexual identity.” More important than sperm to a man’s? I thought this, but didn’t counter. The childishness part repressed there, thank god.

Would I want to have my face with a victorious I put prostate cancer in its place expression made available to public news services? Probably not. But I’m sure there are men who would be delighted.

Not quite sure what I want from this conversation, but I needed to put it out there.

 

 

 

Not Even Gone

Mabon                                                                     Moon of the First Snow

It is so beautiful here around 5 a.m. when the sky is clear, which is most mornings. The stars leap out of the sky, reminders of the power they had when the only light pollution was an evening’s campfire. Orion stands high in the south, moving toward Black Mountain. The Big Dipper disappears behind the roof of the garage in the east, but the pointer stars are visible, showing the way to true north. Cassiopeia, that unhappy queen, extends her jagged W, a slash of stars.

Time travel has been with us since the first human looked up in wonder at the stars. What we see unaided and what we can see with telescopes comes to us from the distant, distant past. So distant that the miles come in units of time. Perhaps, in a way, our lives are like the heavens, still shining after long years, even after death, radiating out from our small sector of space-time to the far away future.

So you might go out and look at the stars and consider the bright lights in your life, still strong and beautiful, wonderful. And remember that someday, you too will shine for others. Not gone, not even absent.
