First Batch of Tumbled Rocks Keeps Me Grounded

When I was a boy, I saw rock tumblers for sale in the Sears Catalogue, but I never had one and never knew anyone who had one. Well . . . decades later I do have a rock tumbler and I have recently learned that there are lots of beautiful rocks to be found only about an hour from St. Louis.



After a month of tumbling in my basement, this is what rocks from a Missouri creek look like (a creek near Farmington, Missouri). They shine even though they are perfectly dry. They are fun to hold and fun to look at. They were all so shy, modest about their beauty, while sitting in the creek. But now they are spreading their little peacock tails. Up close, some of them look like abstract works of art. To see many more images, click on the title to this post and then check out the gallery of photos.

Since I obtained my rock tumbler (a Thumler Model B), I've reached out and found dozens of other people who are passionate about finding and polishing rocks, as well as making jewelry and other objects of art out of them. These rock hounds are all over the place, and all you need to do to make them show up is to mention rocks.



For me, this has been a wonderful hobby, above and beyond the thrill of locating a beautiful rock in a creek or in seeing these polished specimens. I tend to think in the abstract throughout the day. I do it at the drop of a hat. These rocks, on the other hand, are real. I want to hold them and feel them and admire their beauty. This hobby has been an excellent counter-weight to my tendency to philosophize. It has, indeed, kept me "grounded."

Need to Up My Game on Photoshop

I've dabbled with Photoshop over the years, but I have decided to (as Stephen Covey suggested) "sharpen the saw."  In other words, I want to incorporate new tools so that I can get things done better and more efficiently when I use Photoshop.  Shane Parrish of Farnham Street would identify this as "Compounding," which is a really cool concept, especially when applied to things other than earning interest on money.

And what a better time to learn tips on using photoshop than modern times, when you can attend Youtube University or pay a bit from many other online instructors?  I've already incorporated one change when compositing, something I should have done years ago: Instead of trimming a the top image with the eraser tool, I've started making use of layer masks.  That, and use of the "x" key to switch colors from black to white (black conceals, white reveals), has made it a joy to display only what I want on the top layer.  Whenever you make a mistake, it's non-destructive and hitting the "x" key lets you bring back what you accidentally took away.  What you'll see below is an image I created using the layer mask to display precisely what I wanted in my own body (I'm the guy on top).   I'll paste in the FB commentary so you can experience the joke too:

Last night I spotted my buddy Eddie White at the Southside YMCA. Eddie is active duty U.S. Army and I think his military exercise routine requires him to bench press a house. I was happy to serve as his weight-lifting partner.





My body looks pretty tidy, but it took a long time (about 45 min) to get it looking good. I kept zooming in deep to make the cuts precisely and I was using a mouse. My next step in my education is to learn to use the Wacom Intuos Wireless Graphics Drawing Tablet that I just purchased. There's going to be a learning curve, but I've seen a lot of testimonials from people who learn it and love it so much that you couldn't take it back unless you pried it out of their cold dead hands. So that's my next step in my education, my quest to do more than simply "dabble" with Photoshop.

Deep Music Photo

I'm trying to learn some new photo processing techniques by reworking some of my photos from the past. This is a selective color photo of one of my favorite people, Dan Rubright, who is an educator, philosopher, father and lecturer. Mostly, though, I know Dan as an incredibly talented musician who has the knack of transporting himself "inside" of his music and coaxing it to do magic-seeming things. Here's a shot I took of Dan about 4 years ago while he was performing with his group, Wire Pilots. I shot this one through the drums and sticks of Dan's brother Ted Rubright, also a brilliant, multi-talented man. This image brings back vivid memories of their awesome music.



My main challenge in this photo was to pump up the edges without also exposing the noises. In the end, I had to use hand-selection of the blackness, then reverse-texture (LR) in the end, to get the totally black background. There was simply too much noise, given that I had to use high ISO to keep the image tack sharp during the shoot.

Survivorship Bias

Many of us are somewhat anxious, but there are other people out there who lack the ability to feel any anxiety.  Many of those flagrant risk-takers are not with us any more.  They died because they drove recklessly, explored base jumping and generally lived on the edge.  Many others who are no longer with us ignored long term risks like drinking, eating and smoking to excess.  Many of them struggled with cancer, heart diseases and strokes on their way out.

What we see at any given moment are only the survivors. We are the survivors.  We are not living among a true cross-section of humanity.  It's good to remind ourselves of that, because doing risky things puts us at risk, right?  We are living among those who have hit the lottery, and that includes more than a few of the risk takers who are here because they have been extraordinarily lucky.  Those risk-takers are interesting to us.  We watch them, sometimes with admiration, intrigued that they can do dangerous things and yet survive.  They seem to defy death, disease and immense financial risks.  But, again, we forget that we are not looking at a cross-section. Many people jump in and open new restaurants even though 80% of restaurants fail within four years.  When we decide to go out to eat at a restaurant, we are choosing only among the survivors.  The streets are also populated by hundreds of invisible ghost restaurants too.

We are looking at only the lucky ones, and this can mislead us to think that it is relatively easy to do those sorts of things and yet survive.  We might cheerfully announce that we are going to engage in risky behavior without doing a Bayesian analysis. This is exacerbated by the fact that we don't know enough to know the risks, an over-confidence invited by the Dunning Kruger Effect. 

Farnham Street Blog recently took a look at the Survivor Bias:

Can we achieve anything if we try hard enough? Not necessarily. Survivorship bias leads to an erroneous understanding of cause and effect. People see correlation in mere coincidence. We all love to hear stories of those who beat the odds and became successful, holding them up as proof that the impossible is possible. We ignore failures in pursuit of a coherent narrative about success.

Few would think to write the biography of a business person who goes bankrupt and spends their entire life in debt. Or a musician who tried again and again to get signed and was ignored by record labels. Or of someone who dreams of becoming an actor, moves to LA, and ends up returning a year later, defeated and broke. After all, who wants to hear that? We want the encouragement survivorship bias provides, and the subsequent belief in our own capabilities. . . . Most leaps of faith go wrong. It does not mean we should not try, just that we should be realistic with our understanding of reality.



How could I end this article without mentioning the biggest survivorship bias of them all? The eight billion human animals now populating the surface of the earth are all survivors of long unbroken lines of ancestors. We can look around and see only these those human beings who are actually here, not those whose ancestors failed to survive long enough to pass on the next generation at every generation, extending back to the beginnings of life on earth.  This survival of the fittest, natural selection, is sometimes referred to as "breed and weed," nature's amoral culling of ever-new versions of human beings, separating the survivors from those who do not survive.

I find this to be an immensely terrifying and awe-inspiring thought. If you are lucky enough be able to read this, you are a survivor in one of the most long-shot schemes you could ever imagine.  In order for you to be here, your parents had to meet at the right time, be attracted to each other, have sex at the right time and then someone had to take enough interest in you to raise you.  This had to happen twice for your parents to exist. Eight times for your great-grandparents to exist. These numbers grow exponentially as you you look back even a few hundred years.  This is even more stunning when you consider how quickly this occurred--even a millennium is not a long period of time when you break it into generations.  I illustrated this quick passage of time with a hypothetical visual in a post I titled, "Ancestors along the Highway."

On those days when you might not feel special, then, cheer up!  You are special! You are literally a survivor in a long line of organisms extending back to shew-like mammals who found opportunities with the demise of the dinosaurs.  Your line survived all the way back to the first fish to walk on the land, Tiktaalik.  You are a survivor of the sponges, and beyond.

The odds of you being here are infinitesimally small, essentially nil.   So, again congratulations!  That said, good luck with the rest of your day.  And please remember to treat each of the people you encounter as the miraculous survivors they are.  And remember, also, that each of them is a member of your own family.
