Yellowstone 2025 May 2

We love America’s national parks, but Yellowstone is probably our favorite. Our first visit was a year after we married in 1975. For that trip we camped at Pebble Creek in a little pup tent and were able to spend only one day in the park. This year we were blessed to visit Yellowstone for the 8th time, and it was our first visit in early spring. We arrived on May 2, before some of the park roads were open. Nevertheless, the weather, scenery, and wildlife watching were excellent! Rather than roughing it in a tent, we stayed in a cabin at Mammoth Hot Springs. After checking in and unloading the car, we took the road from Mammoth towards Roosevelt to see what we could before sundown. Here are a few of our photos:

Shortly after leaving Mammoth we found our first wildlife: a small herd of bison crossing the road. The herd included maybe a couple dozen adults and a few recently-born “red dog” calves. This would be the first of hundreds (or maybe thousands?) of bison we would see during our almost week long visit to the park.
Shortly after making our way past the bison, we spotted our first two bears of the trip. This mother grizzly and her cub were grazing on a hillside above the road. The sow was intent on foraging, but the cub looked up several times to check out the bear jam developing on the road below. I think the cub has a case of underbite, since the lower teeth kind of stuck out in almost every photo I shot.
The mother grizzly looks rather well off for having come out of hibernation only a few weeks earlier. Not exactly a glossy coat, but not shaggy, either. For that matter, the cub was larger than we expected, but apparently they grow really quickly at this point in their life.
After viewing the two grizzly bears we drove on towards Roosevelt. We found this herd of female elk was grazing a bit off the road, with a few bison further on in the distance. This photo also shows one of the challenges of photographing this big, sprawling scenery. God designed our eyes, mind, and imagination to take it in, up to a point, but it is hard to do it justice with a photograph.
We were heading back to Mammoth towards sunset when we found our third bear of the evening. This black bear crossed the road in front of our car, casting a bit of a shadow in our headlights. It was a little tricky shooting through the windshield, but the lighting and focus worked out reasonably well. We kept our distance, and the bear took his time getting to the other side.

More photos to come!

Homeschooling Meets Reality

Many of my grandchildren are being homeschooled at this time. I say “at this time” because the mix changes from year to year as babies grow up and become old enough for structured teaching via textbooks, worksheets, lesson plans, etc. and because a child who is homeschooled this year might have been in a preschool last year. Education is a dynamic, hands-on process, and parents who are on their game will adapt their children’s education for the good of the child and using the available resources, yet without sacrificing the continuity of the education.

A few weeks ago a friend commented something like, “Homeschooling is all well and good, but sooner or later those kids will need to come out and face reality.” I have heard this kind of thing before, but never from anyone who actively home-schooled their children. I wonder, though, what reality they have in mind.

Is it the reality of the teacher who told me that my daughters did not really need to study math or science, since girls were unlikely to need that knowledge?

Is it the reality of the high school teacher who did not know anything about trigonometry, but was teaching my daughter’s trig class anyway? Is it the reality of the teachers union protecting that teacher from reassignment without regard for the education of our children?

Is it the reality of certain parts of the public school campus being perpetually contaminated by marijuana smoke? The reality of bullies given protected status to bully others?

Don’t get me wrong. I am a product of public school education all the way from elementary school through post graduate work, and the educational system served me well. And my children were blessed with a large number of simply superb teachers in the Lutheran school and public schools they attended, notwithstanding the occasional issues mentioned above.

But other than the occasional incompetent teacher, self-serving teachers union, or pockets of bullying culture, what reality do they need to encounter that they are not already facing? From what I have seen, my grandkids receive an education tailored to their needs, learn at a pace that challenges rather than overwhelms or bores them, and maintain their curiosity, creativity, and interest for critical thinking all the while. But what about their supposed insulation from reality?

Their reality includes group excursions, field trips, and specialty classes with a couple dozen other home-schooled kids, exposing them to a range of personalities and levels of capability.

Their reality includes soccer teams, swimming lessons, horsemanship, and other kinds of enrichment, and some of these activities lead into league competition requiring teamwork, interpersonal skills, and leadership development.

Their reality includes community service, both formally (e.g., in local park districts) and informally (e.g., serving a shut-in neighbor or at church).

Their reality includes grocery shopping, visits to repair shops, trips to the library, trips to the parks, sight-seeing, and travel by car and by air, all of which are permeated with interactions with real people in real communities. Do they live a sheltered experience? No way!

A few weeks ago a friend commented something like, “Homeschooling is all well and good, but sooner or later those kids will need to come out and face reality.” I have heard this kind of thing before, and have heard it said of Christian schools, private schools, and the advanced placement programs and special needs programs in public schools. So what is the common denominator, other than maybe thinking that the grass is greener somewhere else? I am not sure, but rather than dwelling on the grumbling, let’s focus on the children.

Over the years a lot of my friends and co-workers have complained about their children, and our society as a whole often seems to see them as either a burden to be carried or as property to be managed. It is more important, and certainly more comforting, to see them as gifts that God gives to parents; gifts that God expects us to steward, protect, and nurture. We all fall short in this; none of us are perfect parents. Regardless, by the grace of God we do the best we can. I remember my parents teaching me about God, helping me learn the Lord’s prayer, and giving me the best education they could with the best available resources (time, treasure, and opportunities). We tried to do the same with our children, and now they are more than paying it forward with how they are raising our grandchildren. And homeschooling meeting reality is a big part of this.

The Edge of Credibility

A few days ago I was perusing Facebook and noticed a photo of two bears on a road through a beautiful forest. It was a nice photo, and, judging by the reactions, a lot of people appreciated it. A couple days went by, and I noticed what looked like the same photo, but there were four, five, or even a half dozen bears standing or lounging on the road. I was suspicious because bears can be a bit turfy, and it is unusual to see very many bears willingly stay that close to each other. Time went by, and a new photo turned up on Facebook. It was the same view, but this time there were at least 20 bears on the road! That confirmed my suspicion of a faked photo, but the artist was not done. A day or two went by, and the photo below turned up on Facebook:

AI-generated image of bears on a forest highway. Credit and copyright go to the creator of the photo.

So if you saw a series of photos like I described, at what point would you realize that the photos are fake? At what point would they lose their credibility? And how would you know?

In the case of bears, we know that cubs stay with their mothers until old enough to strike out on their own, but otherwise it is unusual to see very many bears together in one place. I have seen as many as seven grizzly bears at a time eating in a farmer’s field, but they all kept their distance from each other. And you have probably seen photos of bears fishing for salmon in Alaska, but they fight for the best fishing spots, and they are certainly not relaxed and lounging next to each other. So our understanding of bear behavior tells us when a photo of bears starts to reach the edge of credibility and when is is clearly a fake.

We need to bring the same sense of reality and experiential understanding into play when we read or hear the news. Sadly, much of the journalism in the US has been moving past the edge of credibility for years. As an editorial by Gerard Baker in the March 3 Wall Street Journal describes it, most of the media has become like a cult religion, saying whatever their customer base wants to believe, and without much regard for objective truth (my paraphrase). I detect this when I see the media asserting things that I can see with my own eyes, or know from personal experience, are not true. You have eyes and experience, so you can detect it, too.

One of our presidents once said, “trust but verify.” Good advice. We really need an honest, objective press, but in these times we need to verify what we read and hear now more than ever. Time to sharpen up our critical thinking skills, ask good questions, check multiple sources, and measure what we hear against what we know. And don’t fall into the trap of thinking, “who can know?” It may take time, but, as they say, the truth will out. Otherwise, if we give up on the truth, we may foolishly believe things as incredible as a hundred bears lounging on a highway.

Take a Long View

A few days ago one of my Facebook friends posted, “Falling like a rock! Have you looked at your retirement funds lately?” So I looked at our retirement funds, and saw that they are doing quite well. In fact, they grew by better than 7% in the three months since Trump was elected last November. In fairness, they were doing well before Trump was elected, too.

A day or even a week of “falling like a rock” can mislead us, and maybe three months of good performance can mislead us, too. It takes a long view to really understand the performance of retirement funds. We lost about 50% of our retirement funds in 2008 when the dot-com bubble burst, but we took a long view, and the funds grew back within two or three years. We lost about 30-40% again in 2022 when government shut down the economy because of Covid, but they grew back again, and then some. Our retirement funds have done quite well over the long haul, averaging 10-12% growth per year despite pandemics, presidents, and the occasionally chaotic market ups and downs. Taking a long view is the prudent approach.

Taking a long view is also prudent when we consider how the meeting between Zelensky and Trump blew up yesterday (February 28). You probably saw selected snippets of it on broadcast news or in social media. If you have time and interest, it would be worth your while to find and watch the entire meeting, which started out well enough but then devolved into an argument in its last few minutes. Why were we shown “selected snippets?” Because the anti-Trump people and the pro-Trump people immediately went into knee-jerk reaction mode about how the meeting was a disaster for Trump or a disaster for Zelensky, complete with cherry-picked video snippets to prove their points. The real questions, of course, are not who started or won the argument, but what is the strategic meaning and future of Ukraine’s war of self-defense against Putin’s Russia, and what should the US do with the situation? If we want the truth, we need to seek it out, but we will not find answers overnight. Alexa, Siri, and talking heads on screens notwithstanding, we need to take a long view to discern how we got here and where we may be going.

The argument yesterday brought some uncomfortable questions into the open. For example, words were exchanged over whether the US or Europe has given more money to Ukraine for supporting their war effort. But how are we supposed to know who has paid what without any audits or accounting, and how do we know how much money went for useful purposes and how much simply disappeared? The press makes much of the idea that Zelensky is the elected president of Ukraine just as Trump is the elected president of the US, suggesting that it was an argument between equals. But what does it mean to call Zelensky an elected president when he canceled elections? Zelensky and his allies claim to be defenders of democracy, and assert that Ukraine is the front line defending democracy, but what has he done to protect freedom of speech, religious freedom, or freedom of the press in Ukraine? Maybe Zelensky is better than Putin on some of these points, but the US press has shed so much dark on the situation that it is often hard to tell.

We need to see the war between Ukraine and Russia as part of a multidimensional contest of geopolitics. The human impacts are awful when you consider the people maimed, kidnapped, or killed, and the carnage continues. Think then on a wider level of economic, agricultural, and infrastructure disruptions, and their consequent humanitarian effects. Then on an even wider level we have Putin’s speeches about how the dissolution of the USSR was the greatest disaster ever to befall Russia, and his apparent desire to rebuild the empire. And we have the mixed history of US involvement with Ukraine over several presidential administrations. All of this leads to near-term and long-term questions for the US, Europe, and NATO.

Only time will tell if my friend’s concern about retirement funds falling like a rock was just an isolated data point or an emerging trend, and only time will tell if the Zelensky-Trump argument yesterday holds real strategic significance. The loud hue and cry from the press will not give us answers, at least in part because it has such a strong flavor of immediate political gratification rather than fact-finding and insight. Instead, we need to take a long view to understand the times. We can take comfort, though, that our welfare and our times are in God’s hands, even if we do not have the whole picture.

Gravity with a Swirl

I am no expert on Einstein’s general theory of relativity, but seem to recall that it predicts that gravity, mass, space, and time are all inter-related. Furthermore, according to the theory, gravity is not constant, but varies. And I am here to tell you, with tongue firmly in cheek, that we have experimental evidence of variable gravity here in our own home!

First, gravity apparently varies from place to place in our home. Books don’t fall very often in our library, stuff stays put on the dresser in our bedroom, and we rarely see anything tumble to the floor in the living room, but gravity seems to be a little stronger in the kitchen. How do we know? Because that is where food, dishes, and any number of other things spill, drop, or fall. Every day. If we had a dog, he would be on constant cleanup duty in the kitchen. And the kitchen is where things not only fall, but break, if they are in any way breakable. Granite counters are not very forgiving when a dish hits it, and the extra gravity we seem to experience in the kitchen has cost us one juice glass after another.

Not only does it appear to vary in strength from one part of our home to another, gravity also seems to include some localized turbulence. We have good observational evidence that gravity in our garage has waves and swirls. How do we know? A green recycling box sits on the garage floor right outside the door. When we have a can, bottle, cardboard, or some other item to recycle, we simply open the door, lean out into the garage, and drop the item into the box. Easy, except that the apparent gravitational swirl makes the item almost always miss the box. It doesn’t matter how far we reach towards the box or how carefully we aim; the can or bottle almost always diverts away from the box and lands on the garage floor. I would think that an invisible elf batted it off course, but the only invisible elf I know of lives in my cell phone to meddle with the voice recognition and spell check software. I don’t think batting incoming cans away from the box is part of their contract, so it must be a swirl in the gravity.

So there you have two sets of observations to support the idea of variable gravity, or gravity with a swirl. What about you? Have you seen any such phenomena at your home?

Contest Theme: Challenge

Last week’s Christian Photographers on Facebook contest theme was more of a challenge than usual. We were asked to submit an image that we setup beforehand using our knowledge of photography and of our equipment. After some thought, I submitted this image:

Wisps of steam rising above coffee in a stainless steel cup.

You might recognize this photo as similar to the image that heads up this “Cup of Brouhaha” blog. Indeed, it is one of several consecutive photos I shot with a cup of hot coffee on that cool morning. But what makes the steam plume wispy? Actually, the white visible portion of what we call steam is microscopic water vapor droplets. I do not have enough expertise in thermodynamics or fluid dynamics to explain the white streaks, or wisps, of water vapor. However, I would speculate that something about the electrostatic properties of the droplets makes them link up into chains, but also provides a slight repelling force between chains so that they remain separate in a laminar (rather than turbulent) convection-driven flow process. Can any of you correct me or shed light on this “wispy steam” phenomena?

By the way, I posted several more photos to my gallery at https://jesseyow.com/electrons-are-cheap/ — enjoy!

Contest Theme: Birds

The theme of last week’s “Christian Photographers on Facebook” photo contest was Birds. As usual, I learn from the other entries as I try to grow past serendipity in the creative side of the art. Here are the photos I submitted for the Birds contest theme, plus some others:

Mallard duck in flight. I have great respect for anyone who can photograph active children, butterflies, or birds in flight. All of them are moving targets (the butterflies move when you least expect it, and fly erratic paths), so it takes a bit of skill and a bit more luck to take the shot. Getting it in focus is a bonus!
Anna’s hummingbird perched in our orange tree. These hummingbirds are in our area year-round, and tend to be a little turfy. They are not happy with other hummingbirds that might come through on migration, and they each usually try to stake exclusive claim to our hummingbird feeder.
Anna’s hummingbird in flight, hovering near the feeder. The throat is red when sunlight hits it at just the right angle, but few of my photos look as spectacular as the ruby-throated hummingbirds seen in other areas.
Rufous hummingbird. About the same size as the Anna’s hummingbirds, these have begun showing up for a week or two each spring as they journey north on their annual migration. We never see them in the fall, so maybe their trip south takes a different route. The Anna’s hummingbirds resent their presence and try to drive them away from the feeder, but with limited success.
Rufous hummingbird perched in our orange tree. He kept careful watch so as to not be surprised by his rivals.
Hawk on a fence, watching for hikers with cameras. Or, more likely, maybe he was watching for ground squirrels. Not sure if this is a red tailed hawk, a Cooper’s hawk, or some other variety.
Red tailed hawk soaring near the Livermore Valley. Not an uncommon sight, but we usually see more turkey vultures than hawks or eagles. The windmills on adjacent ridge lines harvest a number of hawks, eagles, owls, and other birds year-round, but I never hear of turkey vultures killed by the blades. Maybe that’s because the vultures are more likely to stay out over the valleys?
Found this bird on Hawaii (the Big Island) a little over 10 years ago. If I ever knew what it was, I have forgotten. Please send me a note or comment if you know.

If you appreciate these shots, don’t forget to visit my photo gallery at https://jesseyow.com/electrons-are-cheap/ from time to time. I add photos to it every week or two, typically a half dozen or so at a time, and most of them are higher resolution than these. Enjoy!!

Contest Theme: Silhouettes

The theme of this week’s “Christian Photographers on Facebook” photo contest is Silhouettes. I usually enter one or two photos in each week’s contest, but this week I entered three of my favorites. After learning once again to spell silhouette, the real value (for me) lies in the other entries. I understand much of the technical side of photography, but have more to learn when it comes to picture composition and the creative side of the art.

Here are the photos I submitted for the Silhouettes contest theme. You can find these and many more in my photo gallery at https://jesseyow.com/electrons-are-cheap/

Massive sequoia trees in late afternoon sun. You can almost hear the quiet in this Yosemite National Park grove, although “almost hear the quiet” seems like something Yogi Berra might have said. Yogi was a catcher for the New York Yankees; look on line for a sampler of his sayings and you will see what I mean. At any rate, the crisp silhouettes of the trees agains the deep blue sky makes this one of my favorites.
Suspension bridge across the Dardanelles silhouetted in the setting sun. This bridge crosses between Europe and Asia, and has the longest center span (over 6600 ft) of any bridge in the world. There were construction cranes on top of each of the two towers when I shot this photo, but I don’t know if they were there to put finishing touches to the bridge, which has been open to traffic for a few years, or if they are a permanent fixture to support tower maintenance.
Tall grass in the wind. I noticed this photo op on a winter day in Texas. We had just arrived at church for a friend’s wedding rehearsal, and the setting sun highlighted these tufts of grass standing bravely against the cold wind. You might think this was somewhere on the prairie, but it was actually on an island in the church parking lot!

New Photo Gallery: Electrons are Cheap

After trying a commercial photography platform and then a couple of stock photo places to display a collection of my favorite photos, I decided to make things easy and create a clean, simple photo gallery linked to this blog. I call it “Electrons are Cheap” to reflect some of the benefits of digital photography. Although I am still on a learning curve, the first batch of photos is on line as of this afternoon, with a few more to be added (and maybe some deleted) every day or so to refresh the site. If you would like to leaf through a variety of my pictures, here is the link to find them:

The gallery comes up as a set of thumbnail images, but you can click on any of them to see the photo at a much larger size. Enjoy!

Contest Theme: Lighthouses

The theme of a recent “”Christian Photographers on Facebook” photo contest was Lighthouses. I usually enter one or two photos in each week’s contest, but the real value (for me) comes in learning from the other entries. I partly understand the technical side of photography, but have much more to learn when it comes to picture composition and the creative side of photography.

For your interest, here are two of the photos I submitted for the Lighthouses contest theme:

Point Reyes Lighthouse on a calm, sunny day. This is a great spot to look for Gray Whales during their annual migration along the Pacific coast. You can also sometimes see giant sunfish looking like round light patches just under the surface of the water. If you have visited this spot, you probably recall descending over 300 steps to get down to this view. Then you had to hike back up those steps to get back to the path to the parking lot.
Another view of the Point Reyes Lighthouse, taken from part way up the access path. The large building to the right of the lighthouse used to house machinery to power the foghorn. I think the original equipment may have used a steam engine (need to check my history on this), and this was replaced later by a diesel generator. In either case, fuel had to be brought down the path from up on top, so the operators built a track with rails on each side of the staircase so they could lower supplies on a wheeled cart. Nice as long as the cart didn’t get away from you on the steep slope.
Pigeon Point Lighthouse, south of Half Moon Bay and north of Monterey Bay. The two-chimneyed building at the foot of the lighthouse provided office space and workspace for the lighthouse operator. Like the Point Reyes Lighthouse, the original oil-burning and then electric bulb light sources were eventually replaced by automated electric lights designed to blink the same coded signals as used in the original designs. This is another good place to watch for marine wildlife.
Another view of Pigeon Point Lighthouse. I believe that this is now a state park, and the lighthouse is being refurbished so that visitors can climb the spiral staircase inside all the way to the top of the tower. I have been up there once, before it was closed for safety reasons, and the view was spectacular!
Lighthouse (I don’t know the name) on the north end of Kauai, in the Hawaiian Islands. The coded signal for this lighthouse was two quick flashes every 15 seconds, or something like that. You can see the huge Fresnel lens inside the top of the lighthouse; this lens focused the light into a strong beam that could be seen for perhaps 15-20 miles out to sea, and rotated to generate the flashes. The Point Reyes and Pigeon Point lighthouses had similar Fresnel lenses with rotation mechanisms, although theirs might have been slightly larger. Back in the 1920s, this lighthouse saved the first attempt to fly from Oakland, CA to Honolulu, Hawaii. A military plane took off from California bound for Honolulu, but their navigation systems failed part way through the flight, and it was too cloudy for celestial navigation. After at least twenty hours of flight, hoping to find Honolulu, they spotted the characteristic flash of this lighthouse to their south, and realized they were passing the north side of the Hawaiian Islands. Once they knew where they were, they changed course and made it to Honolulu before running out of fuel. Barely.
