Camera Obscura on Greenwood Avenue

A friend of mine who is a retired college professor in the Oklahoma City area posted a link on facebook about a Camera Obscura installation in the Greenwood Area of Tulsa right in the middle of “Black Wall Street” being built by current professor. I decided to go check it out so last Saturday I went down and followed the signs to the third floor offices of the president of the Greenwood Chamber of Commerce. The office had the windows masked over except for a small hole in which was placed a lens of five or six inches in diameter. The amazing thing was that there was image on the other side of the room projected on rolls of paper and the sides of the room.

I used my phone to take a photo of the image.

It was an upside down and flipped sideways image of the scene across the street. I was inside a giant camera! It was amazing. I stood there astounded as the professor, Mark Zimmerman, a photography professor at the University of Central Oklahoma, explained what was happening. This is the earliest form of photography, first started in 500 to 1000 AD. Of course nothing is recorded unless one traces the drawings.

And here is the flipped image. I should have flipped it again left to right. Professor Zimmerman explained that our eyes see upside down and flipped images but our brain does the correctionso for us when it gets the images from the eyes.

Here is an article from Petapixle, with photos and videos showing how Professor Zimmerman made a camera obscura in his classroom.

Here is a link to the Tulsa World article about the installation.

And below is a YouTube video on how to make your own.

So seeing a Camera Obscura was my wow moment this past week.

The Christmas Chute at Sapulpa, Oklahoma

Sorry for the fuzzy foto

I know that many people are just so done with Christmas right now but hear me out. The town of Sapulpa, OK just southwest of Tulsa put on a special light show this year on their main drag which is also part of Route 66. They call it the “Christmas Chute” and it was several years in the making.

People in town conceived of this idea of blocking off the street and putting some platforms above the sides of the street and installing lights.

The result is magical. You have lights overhead and they are a bunch of different themes. You are walking along the streets bathed with light from above. So the effect is that the people watching are part of the show and it adds to the energy.

They are going to do it every year from now on and it will be part of our Christmas goings on from now on.

Speaking of Route 66, this was their section of the show.

The downtown merchants got in the act by dressing up their window displays.

Here is an article from Southern Living discussing the installation and how it came to be.

A Voyage Solar System Walkway “Lifts Off” in Broken Arrow

On September 13, the City of Broken Arrow, OK celebrated their Voyage Solar System Walkway installation. The Walkway is a model of our solar system at a one to 10 billion scale. The scale involves both the distance between the sun and planets but also the size of bodies.

So the sun is the size of a large grapefruit. Earth is a small dot just a few feet away. Pluto, is 2000 feet down the street.

The installation is designed to help people understand just how vast our solar system is by bringing it down to human scale. Voyage was designed by the National Center for Earth and Space Science Education. The first installation was on the main mall in Washington, D.C. Other installations are in Kansas City, Missouri, Houston and Corpus Christi, Texas, Palo Alto, Colorado, Boulder, Colorado, Ocala, Florida, and Lake Charles, Louisiana.

It was interesting hearing about the efforts of many people over the years to get the Walkway installed. Money was raised by local businesses, individuals, and a go fund me page. The city helped out with construction, It was a community effort.

I love that it stretches from the front of an elementary school to the local high school. A ready made model for learning just steps away.

Here’s a video the City of Broken Arrow put out that explains it a lot better than I can.

And of course I made the Voyage to check it out.

2022 Tess 5K Trail Run

Last Saturday I got up bright and early and headed out to Turkey Mountain to run the Tess 5K Trail Run sponsored by the Tristesse Grief Center here in Tulsa.

I decided to go ahead and do a video of the start. After I was done videoing I had to loop around the timer’s truck and across the starting line myself.

A treat for me on this race is that most of it was done on the brand new sustainable trails constructed in the last year. Especially nice was the new trail from the lower parking lot up to the upper level of Turkey Mountain. Those old trails have gotten worse and worse over the years. It got so bad that I hadn’t used them in a long time.

The new trails are like a super highway through the woods. Another benefit is the chances of getting ticks and chiggers from the grass is way less. Also it is easier to pass other people and there is lots of room for both bicyclists and hikers/runners on the trail.

Pretty soon I had passed a small bunch of people and was way behind the pack. That’s alright, I was looking for a great hike through the woods. My running days are over. I do admit though on the smooth slightly downhill stretches I did trot a bit. Probably not over three or four hundred yards total.

And here we split off from the superhighway headed to the left and headed right to one of the legacy trails.

And up the rock garden after we turned south. I got an impromptu invite to a private geological tour of Turkey Mountain last week. I learned that the trail above is caused by alternating layers of shale and sandstone. As the shale layers dissolve and wash away the brittle sandstone breaks and falls down forming a kind of steps. Yep, the steps are ankle breakers!!

DSCF0326

I also learned the top of Turkey Mountain is 300 million years old and has been submerged and re-emerged under a huge inland sea five times by a combination of tectonic and weathering forces. The guy showed us rocks that used to be sand on a beach and lots of little fossilized shellfish embedded in the rocks. It was amazing.

Enough geology for now. We made the loop and headed down the superhighway to the finish. All I can say is that I finished vertically. I didn’t place in my age group. Last year I finished first in my age group. Oh well I finished.

It was a great race, it was easy to register and they had lots of volunteers helping out. Timing was by Tatur, the best in the business in my opinion. They had lots of snacks and water for the participants and I think everybody left happy I know I did.

New Belgium Trippel

They didn’t have beer this year so I had one at home later on. In fact I might have had more than one, I’m not sure. They had tshirts but they are mailing me mine as I registered a little too late to actually get a tshirt at the event.

Tess 5K Trail Run

I’ll be back next year, here is my post from the 2021 Tess Trail Run.

A big thank to the Tristesse Grief Center, their staff and volunteers who helped, Tatur Racing, and my fellow racers.
