This is the first of three posts describing a now-(nearly)-obsolete technology.
Thomas Edison nearly discovered them. In his experiments with heated filaments in evacuated glass bulbs trying to find a suitable incandescent lamp, there were hints. He noticed depositions of material on the walls of the glass tubes. Many scientific discoveries are preceded not by the expression “Eureka”, but instead by the comment: “Hmm, that’s funny”. If he had followed up on this odd result, he might have also invented the vacuum tube amplifier.
Today was my last day of employment, and I will now be exchanging
the two major foci of my creative time.
My interests in photography and astronomy and art was always secondary to my full-time work as a color scientist, an occupation that has provided a long and fulfilling career.
But this particular outcome was something of a fluke; the
education I pursued was a hodge-podge of art, science, and engineering, and my
early career was filled with jobs at not-quite-successful entrepreneurial startups
that caused my dad to inquire where I was working next, because he wanted to
avoid investing there!
I am at the end of my designated time for this
expedition. I must now return from
whence I came, to a civilization density that can host a technical conference,
and will also develop the latent images captured on my film from this remote
As I reflect on the past few days I realize that there are
more things that I would like to do. I
never did get to the Goulding Museum, or to the trading post near there (which
I was told by the traveler couple was closed on the weekend).
On this day, I manage to travel to Four Corners, a
geographic location that is only meaningful to cartographers marking the
human-made political bounds of different territories. There is certainly no physical or geographic
rartionale behind it, as the view from the constructed concrete platform
holding the National Geologic Survey brass benchmark is the same in all
It had been a late night with an unexpected adrenaline rush at the end, and so it was predictable that after finally settling down, I would sleep well into the next morning. After showering and shaving, the next order of business was to upload the photos from my digital camera and assess my success at the guided exposures from last night.
Unfortunately, my laptop did not recognize any of the raw
(.CR2) image files from the camera’s memory card! This was a setback since I was planning to
copy the images to the computer, and then reuse the memory card (I only had two
of them and the second was filling rapidly).
I am staying at the Hampton Inn in Kayenta Arizona. It is not your usual traveler’s stopping place that I have become accustomed to in my business travels. It is an attractive contemporary adobe building, tastefully appointed with beautiful Navajo art and artifacts. Gentle native music is piped to the public areas. An interesting Navaho outdoor exhibit is also well presented. The native American flavor is augmented by modern conveniences—full breakfast, wireless internet, pool, patio, and an attractive and comfortable lobby.
In exchange for the aborted photo session, I enjoyed a full night of sleep and awoke recharged and ready to further explore the area. After last night’s efforts, I recognized a few more things I am in need of: AA batteries (of course), a blanket or tarp, and a stool, adjustable, for help while guiding the telescope at awkward positions. I also needed to fix the too-tight declination gear on my telescope mount. I noticed that there was dust on my digital camera sensor; I needed something to blow it off. These are things I should be able to accomplish during the daytime hours while doing reconnaissance for my next nighttime excursion.
I have long been fascinated by the landscapes of the southwest, and in particular the peculiar rock formations found in Monument Valley, a unique area straddling Arizona and Utah. I am not the only one that finds them intriguing: it is a very popular photographic and film-making target.
When a business trip took me to a conference in Phoenix, I
decided to prepend a personal trip to this Navajo Nation Tribal Park to take pictures
of the night sky. My plans were
ambitious; I wanted to take wide angle star trail photos featuring the famous
buttes, but also, knowing how remote and dark this area would be, to take
guided astrophotos of some deep sky targets.
