Obligatory moon landing post

Fifty years ago today I was eight years old, and it was a summer day in Concord, Massachusetts. I have vague memories of watching the moon landing on our black-and-white television set. But did we watch it while it was happening, or did we watch it on the news later on? I think we watched on the news later in the day.

What I do remember is that it was a big topic of conversation among kids my age. Kids in my neighborhood also talked about how we were going to have to leave Alcott school and go to a new school in the fall. We probably also talked about the new split in the American League between the East and West divisions, and my hero Jim Longborn was still pitching for the Red Sox. But the moon landing had the biggest impact on my imagination, by far.

In fact, it would be hard to overestimate the impact the moon landing had on my imagination. I was so sure there would be regular travel to the moon by the year 2000. When I studied physics in college and understood how much energy it takes to lift humans out of earth’s gravity well, regular travel to the moon began to seem far less probable.

These days I am far more cynical. Before I get excited about moon travel, I want to know where the energy is going to come from, and what the carbon footprint of moon travel will be. These days, I’m more interested in how we might reduce carbon in the atmosphere, to lessen the impact of global climate change. Which means that I’m far more interested in the Trillion Tree Campaign that perhaps “could capture 25% of global annual carbon emissions.” I guess you could say that self interest has prompted a greater interest in ecological science than in astronomy or astrophysics.

Moonlight in St. John’s Cemetery

One of the nice things about living in the old caretaker’s house in St. John’s Cemetery is being able to be in the cemetery after hours. It’s a lovely place on a night like tonight, the night before the full moon: peaceful, with a feeling of quiet transcendence. You feel a quiet connection with all those people who were buried here, and with the people who loved them and wanted a calm place to remember them.

Just as I finished taking this photo, Carol said, “Watch out!” I turned around in time to see a skunk walk past, its tail raised in warning. We retreated back into the house, leaving the cemetery to the moonlight.

…and the “o”s in the poem graphically convey what the moon does from the time it first rises to the time when it is overhead: it appears to grow smaller.

We were driving home as dusk turned into night, and Carol looked into the rear view mirror and said, “Look at the moon! It’s huge!” It had just appeared over the horizon. She wondered aloud, Why did the moon look so huge? Why did it get smaller?

I explained the optical illusion that makes the moon look big on the horizon. “If you hold out a piece of cardboard at arm’s length and put two marks on it showing how wide the moon is — and then hold that same piece of cardboard out at arm’s length when the moon is overhead and looks so small — you can see it’s exactly the same size all the time, even though it looks so much bigger near the horizon.” I actually did just that many years ago; even though I knew, intellectually, what was going to happen, it was astonishing.

Carol said that explanation takes all the magic out of it. But I disagree. How amazing that we see the world in that way! How amazing that there is more than one way to see the world!

When we got home, we walked out into the cemetery and watched the moon rise further into the sky, moving slowly up between two dark clumps of eucalyptus, just touching the point of a smaller Douglas-fir tree. You could see the distance between the Douglas-fir and the moon slowly grow greater. You could see Mare Ibrium and Oceanus Procellarum and Mare Fecuditatis and Mare Nectaris; you could also see the Rabbit in the Moon, grinding with its mortar and pestle; you could also see the Man in the Moon, with his lopsided grin. You could see the night grow darker and the moon grow brighter. Everything changed in a quarter of an hour. We stayed outside watching until it grew too chilly.

Ch’ang-O, the Moon Goddess

Our Coming of Age class took a field trip to the Asian Art Museum to see images of divinities. There we saw a beautiful jade sculpture of Ch’ang-O (Pinyin: Chang-e), the Moon Goddess. It’s just a few inches tall, but highly detailed: Ch’ang-O is smiling beatifically, and she is accompanied by her rabbits, one of whom is grinding something in a mortar and pestle:

Ch’ang-O is still honored in Chinese popular culture, at the Mid-Autumn Festival which takes place on the fifteenth day of the eighth Lunar month. More than one version of Ch’ang-O’s story is told, but the general outlines of the various versions are similar:

Ch’ang-O is an immortal being; she and Houyi are sweethearts. One day, ten suns appear in the sky, the sons of the Jade Emperor of Heaven, and these ten sons cause much damage; Houyi takes up his bow and arrow and shoots down nine of the ten in order to save the earth. Ch’ang-O loses her immortality by offending the Jade Emperor in some way. Houyi obtains a concoction that will make one person immortal (in some versions the pill could be split between Houyi and Ch’ang-O, making them both very long-lived, but not immortal), and this concoction is formed into a pill. Ch’ang-O takes the entire pill herself, either mistakenly or on purpose, upon which she not only becomes immortal, but she begins floating upwards towards heaven. At last she lodges permanently on the moon.

The Rabbit in the Moon

The reason there must be rabbits in the Moon is simple. In the West, we look at the moon and see the Man in the Moon, but in East Asia it is common to look up and see the Rabbit in the Moon; the Rabbit has a mortar and pestle in which it grinds herbal medicine, rice cakes, or mochi (depending on who tells the story). The body of the rabbit corresponds to roughly lunar landscape features as follows: left ear — Mare Fecunditatis; right ear — Mare Nectaris and Mare Tranquilitatis; base of ears — Mare Serenitatis; head — Mare Imbrium; body — Oceanus Procellarum. The mortar which the Rabbit uses for grinding is centered on the Mare Cognitum. For Westerners, here’s a sketch of the Moon Rabbit:

To help you find the Moon Rabbit next time you look at the moon, remember that the crater Tycho is just to the right of the Rabbit’s mortar.

How divine is Ch’ang-O?

Something we ask Coming of Age participants to consider when they look at images of deities is where they would place that deity on the following rough scale:

1. Ordinary human
2. Extraordinary human (prophet, sage)
3. Semi-divine (more than human, not quite a god or goddess)
4. Human who became divine
5. God or goddess with a non-human form
6. God or goddess that acts like a human
7. God or goddess that is far above humans
8. God or goddess so divine that humans cannot know it

In the stories about her, Ch’ang-O started out as — perhaps — semi-divine (more than human, not quite a goddess); then became completely human; then became immortal once more; and finally wound up as the Moon Goddess. Most Westerners, influenced by the strongly Western tradition of ancient Greek philosophy, tend to think of a deity as unchangeable, the “Unmoved Mover”; but far more human cultures have deities that can change in response to events. Thus Ch’and-O serves as a perfect counter-example for Westerners (both theists and atheists) who dogmatically assert that God is perfect and does not change.

Ch’ang-O in popular culture

The story of Ch’ang-O doesn’t leak out much beyond the boundaries of the Chinese American community (or other East Asian communities). But once in a while, the story of Ch’ang-O makes it into Western popular culture. The most notable example of this was just before the first humans set foot on the moon.

Here’s the Air-to-Ground Voice Transcription of the Apollo 11 Lunar mission, from July 20, 1969, not long before the Lunar Module landed on the moon:

03 23 16 18 CC [Capsule Communicator, i.e., Mission Control]:
…The “Black Bugle” just arrived with some morning news briefs if you’re ready.

03 23 16 28 CDR [Commander, i.e., Neil Armstrong]:
Go ahead.

[some material omitted]

03 23 17 28 CC:
Roger. Among the large headlines concerning Apollo this morning, there’s one asking that you watch for a lovely girl with a big rabbit. An ancient legend says a beautiful Chinese girl called Chang-o has been living there for 4000 years. It seems she was banished to the Moon because she stole the pill of immortality from her husband. You might also look for her companion, a large Chinese rabbit, who is easy to spot since he is always standing on his hind feet in the shade of a cinnamon tree. The name of the rabbit is not reported.

03 23 18 15 LMP [Lunar Module Pilot, i.e., Edwin E. Aldrin, Jr.; this was latter corrected to Michael Collins]:
Okay. We’ll keep a close eye out for the bunny girl.

(National Aeronautics and Space Administration, “Apollo 11 Technical Air-to-Ground Voice Transcription,” Tape 61/3 page 270 [Houston, Texas: Manned Spacecraft Center, July, 1969], pp. 178-179.)

— And don’t let the conspiracy theorists fool you: the Apollo astronauts saw no sign of Ch’ang-O, nor of any rabbits, nor of a cinnamon tree (actually a cassia tree in the myth).

An Asian Mary

On a recent visit to the Asian Art Museum, I saw a beautiful mixed media sculpture of the Virgin Mary. The body of the sculpture was made of wood, the head and hands of ivory, a crown of stars of metal, and the hair of actual human hair.

When Westerners think of Asian religious art, they tend to think of Buddhas and Ganeshas and Guan Yins, forgetting that Christianity has had a presence in Asia for more than 1900 years. So of course there are Asian Christs and Asian Marys.

This Virgin Mary was made in the Philippines, to whence Christianity was brought by European Christians about five hundred years ago. The sculpture cannot be precisely dated, but was made sometime between 1650 and 1800.

Anyone familiar with European Christian art from the Middle Ages and the Renaissance will recognize the iconography of Mary standing on a crescent moon. But some of the details feel Asian. Mary’s facial features do not look stereotypically European, and according to the wall label next to the sculpture, “Early Spanish reports describe artists of Chinese descent as well as Filipino artists carving these images in the Philippines.” The treatment of the draped fabric feels non-European to me, especially Mary’s blue robe, which takes on a life of its own in a way that European Renaissance sculptures, based on classical models, never do; it feels more like the flowing, moving fabric found on some Chinese sculptures, or even on some Medieval European sculptures. I particularly like the use of human hair, a material that anchors Mary in the human realm, and keeps her from drifting into a realm of inaccessible transcendence.

In short, here is a deity that incorporates European iconography with Asian forms and sculptural traditions; she is a globalized deity who also links the human to the transcendent realms.

Three views of the eclipse

1. HF wavelengths

“Although the ionospheric effects of solar eclipses have been studied for over 50 years, many unanswered questions remain,” according to HamSci.com, organizers of citizen science experiments designed to test the propagation of radio signals during the eclipse. I was not set up to actually participate in the citizen science experiments organized by HamSci.com, but I turned on one of my amateur radio transceivers to monitor high frequency transmissions during the eclipse; specifically, I monitored PSK-31 transmissions centered on 14.070 MHz, where I knew there would be a lot of activity.

Propagation was good before the eclipse started; at about 9 a.m. there was a fair amount of activity on 14.070 MHz, and I was receiving stations as far away as Colorado. As the eclipse progressed, I received fewer and fewer transmissions, and by about 10:20 (when the eclipse was at its maximum here in San Mateo), there were almost no readable transmissions. By now, the band is more active, although the stations I’m hearing are all on the West Coast.

My observations were completely unscientific, and it will be interesting to see what comes out of the data that the folks at HamSci.com are gathering during this eclipse.

2. Visible wavelengths

My plan was to project an image of the sun through binoculars mounted on a tripod. The sky was covered by stratus clouds (high fog) at 9 a.m., but by 9:45 the clouds began to break up and Carol and I got a few views of the moon’s shadow slowly moving over the sun’s disk. It became mostly clear by 10:20, in time for the maximum. Then it stayed clear, and I was able to watch the moon’s shadow slowly slide away from the sun.

One of the benefits of projecting the eclipse is that I could see the rotation of the earth as the projected image slowly moved as the sun changed its relative position in the sky. This was a good reminder that an eclipse involves relative movement of three astronomical bodies: sun, moon, and earth. And if I had had access to better optics, I could have projected a larger image and watched the movement of sunspots as well.

3. The emotional response

At about 10:20, when the eclipse was at its greatest extent, it was noticeably dimmer than it should have been. The light was about as bright as it would be around sunset — the difference being that the sun was high in the sky, so the shadows were short. It definitely felt a little eerie.

But mostly what I felt was a sense of wonder. This was the most astronomical fun I’ve had since watching the transit of Venus a few years ago.

The rising of the full moon pulls us away from the mundane world of traffic and pollution and politics, drawing us up into a different place: the world of Chang-O and the Rabbit in the Moon; the world of the Apollo moon landings; no, different than both these things. Something primal, something that draws our eyes up at the time of the full moon, even though any mention of the moon is trite, as trite as poems that rhyme June and Moon. I still can’t believe that I live in the northern California subrubs, where I can see the full moon rising up over both palm trees and redwood trees at the same time. I want to pretend to be bored, but I am never bored by the rising moon. It is always new, always a wonder.

Black Mountain trail camp

More and more, I’m coming to believe that if organized religion is going to help fix global climate weirdness, we have to get out of our buildings more. Not that we should get rid of our buildings — we need our indoor spaces to accommodate a wide range of human person, including elders. But we also need to do more outdoor ministries.

Last night, group of youth spent the night at the Black Mountain trail camp, in Santa Cruz Mountains behind Silicon Valley. The hike in is two miles, with a total elevation gain of about 500 feet. We got to the camp, set some tents and made dinner.

After dark, some of us took a quick walk up to the summit of Black Mountain (elev. 2,800 ft.) and looked down at the bright lights of San Jose and Silicon Valley on one side, and the mysterious fog creeping up the valley on the other side of the Santa Cruz Mountains. Come to think of it, that image could serve as a metaphor for the role of organized religion in understanding humans’ place in the universe: if we wanted it to, organized religion could be the metaphorical high point where we could see both human-centered life on one side, and non-human-centered life on the other side.

Back in camp, some of us slept in tents, and some of us just slept out under the stars. The moon was really bright, so I slept restlessly. I awakened before dawn, and snapped this photo of our campsite:

BlogMar2815

Dawn from the top of Black Mountain was beautiful: orange sky at the horizon and pink clouds above. After a breakfast of bacon hot chocolate, and more bacon, we hiked out, and were back in Silicon Valley by about ten. It was a short trip, but short trips fit in well with the busy schedules of our teens.

The Moon and the hare

Another in a series of stories for liberal religious kids. This story, from an extinct language group in Southern Africa, offers an explanation for the beginnings of death.

The original language this story was told in was the |Xam language, which is now extinct. The people who spoke this language are part of a larger ethnic group commonly referred to as “Bushmen”; in academic circles, the term “San” is used. Both names may have pejorative connotations for the people to whom they refer; I have chosen to use the academic term.

———

When the San people first saw the new moon, they would look towards it, and put their hands over their eyes, and say this:

“Star, O Star, yonder in the sky!
Take my face there. You shall give me my face there.
When you have died, Moon, you return, alive again;
We no longer saw you, and then you came again.
Take my face that I may resemble you.
You always return, alive again, after we lose sight of you.
It was the hare that told you that you should do this.
It used to be that you told us that we also should return,
Alive again, after we had died.”

Having said this prayer, once a man of the San people named Dia!kwain followed the prayer by telling this story:

In the beginning, the hares looked much like a human beings. And when they died, they did not die forever, for after a time they would return to living once again. Continue reading “The Moon and the hare”
