Septuagenarian Surprise

Hiking through the desert in the morning after an overnight photo session.

“Can I still do it?” and “Will I still enjoy it?”

I find myself asking these two questions about various activities I undertake.  Now maybe you are thinking I am making oblique references to sex, but so far, that hasn’t been in the category of activities I am questioning. 

I noticed that, after turning 70, my superpowers appeared to be diminishing.  This was a surprise to me because so far, at every decade mark, I had felt little difference from the previous one.  There were a few things I suppose– certainly my appearance has changed as I have grayed, but for the most part, my capabilities have held.  

Until now.  I am starting to notice that my flexibility is less; I am stiff in the morning; my strength and stamina are diminished.  Something has happened to the sinew and grit that powered my younger self.  The analogy I entertain is:  “the rubber bands are drying out”.  

My limitations became apparent in a recent outing to take pictures of the night sky, an activity I have enjoyed for decades.  One of my life highlights was recording pictures of the night sky on Racetrack Playa in Death Valley a few years ago.  Currently, it is a similar trip with a hike to a collection of geologic features in the badlands of New Mexico.  I treated it like many others I had undertaken, but this time, things felt different.

During my “Nightscape Odyssey” in 2001, I would survey a candidate night sky site during the day, making notes of how to get there, what compositions were promising, and generally getting familiar with the area.  I would then return to the site later, as twilight approached, or sometimes even in the dark, and set up my telescopes and cameras.  It made for a long day, and a long night, and I was usually exhausted the next morning.  Nevertheless, after a morning nap, I would start the process all over again for the next night’s session.

This time, I was prematurely worn down after the initial reconnaissance and had to postpone the nighttime excursion until the next day.  I didn’t expect that.  Maybe it was the heat, or maybe it was the elevation, but those were factors before, and back then I still had the energy to carry on.

The lure of an image in your mind’s eye is a strong motivation, and I was very excited to see if I could capture the Milky Way behind the Alien Throne, my target for this outing.  I described the overall experience previously, but I will now describe some of my other reactions as I undertook it.

I mentioned that my backpack was heavier than I expected.  Yes, it had an excess of camera gear, but that was the payload.  The rest was support: water, snacks, and protection against the desert night.  The total came close to forty pounds, a typical number for a much longer trip.  It was well within the range of packs I had carried before, and tonight I only had to go 1-1/2 miles over relatively flat terrain.  I put it on, cinched the hip belt, and felt the familiar shift of my center of gravity as I took the first steps down the trail.  It felt good to be doing this again.

As I continued, I noticed that I could feel the load in my legs.  This was not a daypack.  I could also sense some strain on my knees.  This reminded me of an incident that happened a previous time I had carried this pack.

It was fifteen years ago.  I had been on a weeklong backpacking trip, and on the last day, while climbing a ridge along the Lake Superior Hiking Trail, I experienced a sudden collapse of my right knee.  It was truly a surprise; I fell to the ground.  It wasn’t painful, my leg was just uselessly limp.  My hiking buddies helped me back to my feet, but I couldn’t sustain the weight of the pack and collapsed again. Fortunately, it was only a short distance to our destination, and by distributing most of my load to the others, we were able to get there.

But here I was, hiking solo in a wilderness area as night approached.  If the same thing happened, what would I do?  I was a mile from my car, but to get there, I would have to abandon my load:  $5000 of camera gear.  Well, I guess I should factor that into my choice to embark on these excursions!

I carried on.  And I carried the hiking poles that Poldi had lent me.  I had always considered them a nuisance, getting in the way of my path and interfering with handling a camera, but I was now starting to appreciate them.  They bore my weight and guided my traverse across the ruts and ridges in this rugged landscape.  What was once an annoyance has now become a dependence.

I made it to the Valley of Dreams, following the route I had traveled the previous day, but the Alien Throne was another half mile through uncharted ridges and eroded gullies.  I could see the destination on my GPS, but the terrain was not adequately shown.  I found myself blocked by box canyons and cliffs.  My strength was waning, the sun was setting, and I wondered how many more of these obstacles I could clamber over.  If I became stuck, I would just make the best of things, taking pictures of whatever features were around me, even if they weren’t my prime target.  It could still be a wonderful evening.

I was getting close, but a sudden drop-off was in the way.  It was too high to scramble down, especially bearing my pack.  So I removed the pack, lowered it over the edge, and then eased myself over and dropped down onto it.  This was the last obstacle.  I rounded the corner and found the Alien Throne!  But it was not lost on me that this was an obstacle that in earlier days would not have presented a challenge.  Further, had I not had a semi-graceful landing on my pack, what injuries would I have sustained?

It was a small barrier, but I was stranded on the shelf 5-feet above the valley floor I needed to get to.  I dropped the pack and eased myself over the edge onto it.

I filed those thoughts away as I looked over the theater containing the Alien Throne.  I needed some time to recover my breath after the stress and strain of navigating these eroded features, but I was aware that the light was rapidly changing.  I needed to get my cameras set up.

This is a very pleasurable part of the adventure.  I am finally at the site and can look for the compositions I have imagined.  It is a mix of guidance and guesswork.  I have some tools to help with orientation and timing, but it really takes placing an eye to the eyepiece to see how the landscape fits the sky.  There are technical issues to resolve as well: exposure times, lens apertures, focus, and shutter intervals.  These keep me narrowly focused on my goals and shut out any other concerns (I’m oblivious of the need to worry about scorpions).

But as I placed each camera and tripod in its place, I could not help but notice each difficult position, and each awkward angle I had to assume in doing so.  Yes, the terrain is uneven, and the viewpoint requires the right height and angle, whatever it needs to be for the composition, but I don’t remember it being such a physical strain to achieve it.  

Kneeling is a particular motion, required for just about any adjustment.  I find that it is hard to get back up.  And when I drop something, it becomes a major project to recover it.  The aches and pains of drying rubber bands were making themselves known in this otherwise pleasurable setting.

But when the cameras are each in place and running, I heave a sigh and settle in for a night of watching the heavens flow across the sky.  It will be an hour or more before the cameras need attention.  This is another pleasant part of the nightscape adventure.  I record the photographic details of my experiments in a notebook and contemplate what the outcomes might be, and what subsequent exposure tests I should undertake.  When I am with Poldi, we find spiritual and intimate activities to fill the time under the stars, but on this night I am alone, at least for a while.  Soon after my cameras were set up, another night sky photographer arrives.  We share our stories while the stars move above us.

We eventually retreat to our refuge against the cold desert night.  I am in a sleeping bag tucked into a recess in the rocks.  I relax here, watching the sky above and listening.  There is a cricket chirping.  I am astounded at how loud it is, and then I remember, I now have “bionic ears,” recently acquired hearing aids, another indicator of crossing the seven-decade threshold.  They have been tuned to amplify the high frequencies that I was previously missing.  This helps me to understand the speech of women and children, but it really helps me to notice the frequency of cricket chirps, which are slowing as the temperature drops.  The chirps keep me awake.

But eventually they stop, or maybe I drift off.  When my alarm goes off for the next exposure event, I climb out of the sleeping bag and stumble toward the camera that needs attention.  The moon has set, and it is now purely starlight that guides me.  Plus my flashlight, because starlight is just not enough, at least on this uneven terrain.  As I navigate over the rocks toward the camera, I recognize the precariousness of my path.  At home, at night, in the dark, I must sometimes navigate to the bathroom.  It is much easier with a nightlight– so we have installed them.  Here, in the certified dark sky wilderness of New Mexico, I am on my own.  I am aware and notice the uncertainty of my steps on the sandstone terrain.  Loose gravel and vegetation contribute to the hazard.  Once again, I recognized that if I fell and was injured on one of these camera servicing missions, I would no longer be enjoying the night.

But the cameras, with their new exposure settings and refreshed batteries, continue their nighttime schedule.  I return to my nook to marvel at the Milky Way, now high in the sky.  The cricket reminded me that I have bionic ears, but the sky reminds me that I also have enhanced eyesight.  

The miracles of modern optics can correct for obscure vision conditions, including astigmatism and other aberrations.  I put on my progressive prescription glasses so that I could appreciate the full glory of the night sky, beyond my now compromised seventy-year-old built-in lenses.  It was a bust.  For whatever reason, my glasses made the view worse, not better.  I will be investigating this failure, but in the meantime, I enjoyed the night sky without optical assistance.

The pleasures of the night continued; the cameras were serviced despite the risks, and eventually the sky began to lighten.  Dawn was approaching.  

The exposure schedule ended as the sun rose, and I gathered my equipment, preparing for the hike back. The night before, I had reached my destination just before my strength ran out.  Now, after a night to recover, I expected an easy hike.  I knew the way.  And it started that way, but soon became hard.

It was not a difficult trail, mostly level.  And the sun was still low, the temperature moderate.  The path was easy, but on encountering the slight banks in and out of a dry creek wash, I was annoyed that I could not just scramble them; I had to take carefully placed steps.

Only a mile and a half back to my car.  Yet, I found my feet becoming “heavy”, without the lift to rise ever slightly for the next step.  And they were sloppily planted in that next step.  It was the closest thing to a stagger, and I realized it.

So I paused for a rest, dropping my pack for a while.  Sitting on a rock and taking some water, one of my hiking poles fell to the ground.  I cursed.  Now I would have to bend over to get it.  When did just stooping down become such a pain?  I have never enjoyed getting under the desk to plug in computer or power cables, but just bending over to pick up something I dropped?  That’s new.

Reaching the point of involuntarily dragging my feet was a new experience, a physical regime I was unfamiliar with.  It made me appreciate the limits that people sometimes overcome, not just for recreation, but for survival.

And it added to my list of items to balance against the pleasures of my remote outings.  I really enjoyed the hours in the desert monitoring cameras and watching the galaxy cross the sky.  But I have become aware of the risks I am taking on, some of which seem to have increased over my years.

I was halfway back.  I was aware of the remaining distance, which was more than the physical distance.  It included the depletion of my energy reserves.  I may have been staggering, but I was not to the point of stopping.  I hoisted the pack and continued back to the car.

I can now declare that “I can still do it”, and I will also declare that “I still enjoy it”, but I must temper this last statement by acknowledging that the enjoyment is diminished by the increased risks I take on.

Life is filled with tradeoffs.

It may seem that I am complaining about getting old, and I guess I am, but I am also thrilled that I am still around to do so.

If I look back a little, I might be able to extrapolate how this next decade will go.  So far so good.  I hope I can be as spry as Dick Van Dyke when I get there!

Daily Doses of Distress

I find the news these days to be very distressing; I’m surprised by how many things being enacted by our leaders seem to contradict the values I was raised with.  So I retreat to the world of what’s real, which to me is the world of Nature and the physical laws and relationships it embodies.  

Science and math are incredibly powerful tools.  Despite their unpopularity, their predictive abilities are unrivaled.  So I use them to assess the world around me, and recently I have been exploring the limits of our cultural assumption of unlimited growth.  Unfortunately, I find that we are reaching those limits, and I suspect that our current political conflicts may be related to them.

I don’t want this blog to become dominated by such heavy material, so I will simply reference the next essay, Defending Malthus, in my “limits” series, for those who find them interesting.  

Everyone else can hold tight.  I’m on my way to New Mexico, hoping to hike the Bisti Badlands again and take some photos.  That is what will keep my attention away from the daily dose of discouraging news.

On Unlimited Growth

Many of you follow my eclectic blog posts hoping that one of them might appeal to you.  They span a broad range from personal to professional, craft to art, simplistic to technical, worldly to cosmic.  I sometimes offer my opinions and back them up with data.  In today’s data-challenged world (not from a dearth of data, but rather the challenges from those who don’t like the data), it is hard to make a compelling argument.

Nevertheless, I recently embarked on exploring a topic that has always bothered me:  the idea that we can solve our problems by economic growth.  I can see how it can solve certain short term problems, like borrowing money to pay back interest on prior loans, but it didn’t seem like a viable long term strategy.  We live on a finite planet and so eventually we would end up against practical physical limitations, right?

It is obvious to a physicist, but seemingly not to many others.

Over the last month, while staying warm in our natural gas-heated home, I looked into the future of fossil fuels and their impact on our global economy.  I crafted three essays which are more technical than many of my posts, and may not be of interest to many of my followers.  So don’t feel compelled to digest them.  

But if you are curious, here are brief descriptions, with links.

The Twins Paradox – a lifelong puzzle

When I was studying physics in college, one of the early subjects was Einstein’s special relativity theory.  The subject is called “relativity” because it explains the physics of objects moving relative to each other.  It is “special” because it only applies to uniform relative motion, not motion induced by gravity, which is covered by “general” relativity, which Einstein described a decade later.

Special relativity replaced Galileo’s and Isaac Newton’s earlier theories, which were superb at explaining falling objects and orbiting planets, but had run into trouble explaining the properties of fast-moving electrons and light.

It is an early subject in the physics curriculum because as students, we were just learning the techniques of calculus and linear algebra; techniques that are helpful, but not required to understand special relativity.  Most people are familiar with special relativity, and even if they don’t understand the details, they have heard “E=mc2”, one of the consequences of it.  They may also have heard about time dilation, the effect of a moving clock slowing down relative to a stationary one.

16mm Home Movies from Mid-20th Century

As I mentioned in an earlier blog entry, I inherited a collection of 16mm movies made by my two grandfathers, each an enthusiastic amateur and early adopter of photo technology.  I have been struggling with their fate, as they consume a not-inconsiderable amount of space in my archives.  Space that could be used to store other useless artifacts.

They have now been (mostly) digitized. And one can find them summarized at this page.

I have great difficulty getting rid of things.  As someone who respects the historical path that brought us to our current time, place, and relations, it is hard to discard mementos, especially (for me) photographs that captured moments along that path.  As a scientist, I am loathe to delete “data”, that might someday be valuable.

I have to acknowledge the slim likelihood of such artifacts becoming valuable.  I hold no conceit that some biographer will ever be looking for scraps and clues identifying the influences on my own childhood.  I like to think that my contributions to society have been positive, but probably not worth much more than an oblique reference in an obituary (“he was a curious man”).  But maybe there were things in those movies that would be of interest to someone else. I didn’t know how to find that audience.

So the movies, spooled on metal reels of various sizes, lay dormant for years.  When I wondered about their ultimate fate, I realized that eventually, they would have NO meaning to anyone, even if it were possible to view them.  If there was any value to be extracted, it would have to be now, by me. 

I described that initial effort in the previous post on this topic.  Here is what has happened since.

LEGOs for Life

Grace and Hoan, with mom Poldi, after presenting me with this terrific gift.

I recently received a most unexpected gift, an extravagant thank-you gesture from newlyweds for being part of their marriage (as driver and other small supporting roles).  Somehow, they found something that would appeal to me on many levels, something I would never consider for myself:  a LEGO set!  And not just any LEGO set, a large and elaborate architectural depiction of an A-frame cabin, with thousands of parts.

It had been inspired by a LEGO enthusiast from Italy, who enjoyed creating Lego models of houses in his spare time.  Evidently, there is a large community of LEGO fans, large enough that there is a program for them to submit ideas and models for the pleasure and approval of other fans.  Those with the highest votes are selected to become an actual LEGO product.  How brilliant!  Let fans come up with cool ideas, and then manufacture the most popular, knowing that it has already passed the “will they like it?” test!  The A-Frame Cabin was the most recent of such crowd-sourced concepts, released just days earlier.

My step-son and his new wife did not know of my past LEGO history.  They did not know that I had been a member of the LEGO Builder’s Club with my son in the 1990s.  Or that his LEGO model of the Eiffel Tower had been featured in their newsletter.  They did not know that I had authored a software program, LegoShop, to create models on a computer screen in a time before computer graphics, video games and virtual reality had been fully invented.  They were unaware of how much time I had spent with a micrometer, reverse-engineering the basic LEGO brick and many other parts to make my virtual models.  They did not know, using that program, I had created a Christmas card featuring a LEGO ice castle with Santa and a reindeer.  They did not know that I had insisted on visiting LEGO Land during a visit to Malasia.  They knew none of this personal LEGO history.

Yet they somehow knew that I would fully appreciate this gift. I’m impressed.  

The LEGO Builder’s Club featured my son’s Eiffel Tower as a Member Masterpiece, circa 1992

LegoShop, an application that allowed the creation of LEGO models from a library of virtual parts.  Some older readers may recognize the window format of early Apple computers.

In LEGO-Land Malaysia, 2015

I have been a dormant LEGO builder for many years and have not kept up with the latest sets and themes.  But the skills to assemble LEGOs don’t go away, and even if they did, the remarkable instructions provided with the kits can be followed in any language, even by builders who, like some of my grandchildren, cannot yet read (but you DO need to know your numbers).

In the case of an enormous set like this one, the instructions run to 333 steps, requiring two books to contain all of the illustrations.  The thousands of parts are partitioned into 16 bags, opened one at a time while following the next series of steps to assemble them.  The process is much like putting together a jigsaw puzzle, finding the next target pieces, and mating them in correct position with the previous ones.  Eventually, the parts that tumble out of the bag are all in place, and I can take a moment to appreciate the growing model.

A view of the partially built cabin. The front door opens into an area with bookshelves, a guitar, and an umbrella stand. The owner appreciates rocks; a geode is prominently displayed next to the record player.

What a pleasure to receive a gift like this.  Something created by a LEGO fan and endorsed by a global LEGO community of enthusiasts!  I am savoring the construction steps as I go through them, but have recruited the assistance of other LEGO experts.  I plan to post photos of the completed project!

Indirect Endowment

[I write this not to gain credit or accolades, but as an attempt to inspire others who may have been blessed by similar good fortune or have been more successful than expected in saving for their futures to consider what to do with their “excess”.] 

My dad once told me that he was planning to “spend his children’s inheritance”.  It was his lighthearted way of saying that he was not going to restrict his spending during retirement.  He intended to pursue his passions for inventive projects and for philanthropic activity, especially for educational causes.  And that his children should continue saving for their own financial security.  None of us expected any different.

Well, he failed.  Despite his efforts to create the ultimate ham radio station, and to support his grandchildren through college, he left a surplus.  Not a Warren Buffet or Bill Gates level of wealth, but certainly more than we expected from a man who worked for a salary and who, while we were growing up, paid the mortgage by keeping our daily expenses to a minimum.

Stonehenge and Solitaire

My visit to Stonehenge in 1994

When Management Graphics adapted their film recording technology to support motion picture film formats, it was quickly adopted by movie studios to bring special effects from their computer memory images on to film.  There were some problems however, and one of the most serious was the difficulty in obtaining the full brightness range found in typical scenes, especially when they included lights—candle light, desk lamps, car headlights, streetlights.  Any light source, even a glimpse through a window to the bright outdoors, would cause a large flare in the final film frames, washing out detail in the scene.  Our customers complained, and we started down a path to research and solve the problem.

We understood what the fundamental issue was: halation, an effect caused by the glass faceplate of the cathode ray tube used for creating the image.  The bright spot on the phosphor screen was internally reflected at the glass surface which then illuminated the phosphor coating.  If phosphor were black, this would not be a problem, but phosphor coatings are white, as are most materials made of fine powder, and it resulted in this internal reflected light overexposing the film.  In the absence of a black phosphor, there were few other ways to mitigate the halation effect.

An example of halation on a photographic film plate.  The circular haloes and flare are apparent around the street lights in this 1910 image.

One of our customers was incorporating our film recorder into a full workstation system.  Quantel, a company in Newberry, England, had become successful in the early years of digital video and was looking for a way to expand its editing tool offerings into the motion picture market.  Quantel’s engineers understood the halation problem as well, but they didn’t want to rely on our figuring out a solution: they had an aggressive development schedule.

An Oscar for Solitaire

I’m occasionally asked about the Academy Award that my colleagues at Management Graphics received. It was during the early days of computer-generated special effects in motion pictures. A product I contributed to, the Solitaire Image Recorder, was selected as a technology advance worthy of the Academy’s Technical Achievement Award.  These awards are delivered in a parallel ceremony to the one we are all familiar with.  It features celebrities of a different kind: nerds.

This is the story of how my friend Rick Keeney ended up on that award stage. It has been adapted from his personal account and is a bit technical, but don’t let those details detract from the overall story line.

Rick Keeney, with the Academy Award for Technical Achievement, 1992.

Invention and Innovation

In the formative days of digital photographic imaging, output back to film was produced using specialized, often hand-built, image recorders that were difficult to align, calibrate, and keep running consistently.  As one of the early companies in the business of building and selling graphics workstations, Management Graphics (MGI) recognized that the drawbacks of the available film recorders were limiting its workstation sales.  MGI kicked off a development effort to build a film recorder that would be a robust and easy-to-use product.

Science or Sentiment, Generalized

Career “trophies”, coffee mugs, one of which was created by dye printing technology (depicting our development team), the other a memento commemorating the issue of an arcane patent.

There is a more general problem related to the “what to do with old lab notebooks” that some of us face.  It is what to do with our shoeboxes of photos (virtual digital shoeboxes and real ones).  And written correspondence.  Love letters.  Birthday cards and holiday cards that caught our attention enough that we saved them.  The trophies, actual physical trophies, or the certificates of commendation for a job well done.  Birth and death announcements.  Souvenirs of our travels, the mementos of the high points of our lives. 

All of them carry great meaning to us, invoking a romantic haze of fond memories from those times and places, for those people and events.  Yet those memories are internal to us; they are not shared, even with the persons we may have shared the moment with—at least not exactly. Each of them has his or her own version of those scenes.  And they are not shared in the same way with our children, and certainly not their children.  Our lives are an abstraction to them.  They weren’t even around when the main story was unfolding.

I have come to realize this in the last few years as I have processed the items left behind by my parents after their deaths.  I have a high regard for my father’s technical acumen and his many projects.  Some of them were to gather and archive family history, others documented his personal interests.  He was always an early adopter of technology and embraced digital photography well before I did.  He acquired a large collection of both film and digital pictures, organized in shoeboxes and digital folders.  He worked to digitally scan historic family photos that dated back to the 19th century. 

There is a treasure trove of history here, some even recent enough to overlap with my own, yet I do not find myself compelled to explore it.  And therein lies the problem.  If I am not inspired to carry forward the artifacts of prior generations, why would I expect subsequent generations to propagate mine?
