LOOPY - Arms Race

http://zhurnaly.com/images/LOOPY/LOOPY_Arms-Race_Escalation_2021-09-17.jpg

In an "Escalation" situation (like the US-USSR nuclear arms race of the 1940s-1980s) a tiny initial difference grows exponentially. Each of the actors in this LOOPY sketch adds to its weapons stockpile at a rate governed by its (delayed!) perception of the other's stockpile size. The result is a stair-step climb toward infinity.

What can stop this dash to destruction? One way is to change the system's structure – breaking the positive feedback loop via arms-control treaties, mutual inspection, etc. Other ways include economic ruin, or thermonuclear war ...

Practice of Contentment

In A Morning Cup of Yoga, Jane Goad Trechsel offers gentle thoughts on nonattachment, letting-go of expectations. In the section "Practice of Contentment (Santosa)" she writes:

A beautiful niyama to work with is the practice of contentment, or santosa. In this practice, we decide that in this very moment we will be contented, no matter what storms are threatening. The fact is, there are always storms. If we wait for things to become as we demand them to be in order to be contented, we will always be waiting. Contentment can be enjoyed in small tastes. On the worst of days, it's possible to pause and look at the world with unclouded eyes for a moment, see the sky, hear a bird, see a child's face and say, "For this tiny moment, I choose to be contented."

Begin to look for those moments. When you crawl into your bed at night, let your body relax. Let go of the concerns of your day. Stop trying to control events and people around you, and, as the Beatles said, "Let It Be." When we quit fighting and resisting, contentment arises naturally.

LOOPY - National Economy

http://zhurnaly.com/images/LOOPY/LOOPY_National-Economy_9-factors_2021-09-14.pngCausal flow diagrams can illustrate complex relationships among multiple drivers and can suggest archetypal system patterns. For instance, this cartoon of nine factors in a modern national economy shows a hypothesis about how boom-and-bust cycles might emerge. The nodes Money Supply, Interest Rates, and General Price Level appear to be in an unstable loop. In the short term the stock market tends to benefit from money supply increases – but that results in long term increases in interest rates and prices, which then hurt the stock market. It could all be part of a "Fixes that Fail" archetype.

Reading the Book of Nature

From "NASA's New Telescope Will Show Us the Infancy of the Universe" by Rivka Galchin in The New Yorker, a beautiful concluding metaphor:

The seventeenth-century astronomer Johannes Kepler studied the physical world for the messages he felt that God had written into the Book of Nature. Galileo, in fact, had supporters inside and outside the Church. Sometimes people in power have been reluctant to acknowledge the truths that science uncovers. Each time we look farther, our universe gets larger. Or, depending on your perspective, we get smaller. Astronomers take the position–an incidentally ethical one–of being radically in favor of knowing.

Bob Williams, the former head of the Space Telescope Science Institute, grew up in a Baptist family in Southern California, one of five children. He'd wanted to be an astronomer since the seventh grade, when he received a pamphlet on astronomy in science class; he then saved his paper-route money to buy a telescope. He earned a scholarship to U.C. Berkeley and studied astronomy there. "My father didn't want me to go to college," he said. "He told me that if I went to get an education I would lose my faith. And he was right about that. We were raised to take every word in the Bible as literally true. But then I was learning about continental drift. About evolution." Williams said that he is often asked about faith. Many traditions use the term "God" to mean, basically, everything that is. In that view, the universe itself is the Book, and astronomers are reading it as it is.

LOOPY - Success to the Successful

http://zhurnaly.com/images/LOOPY/LOOPY_success-to-the-successful_2021-09-07.jpg

Sometimes a tiny head start grows into an enduring advantage. In a "Success to the Successful" situation two positive feedback loops wrestle for dominance. When A gets ahead A gets more resources, which helps it move further ahead of B, which gains it still more resources – and on and on, until B is driven into bankruptcy. (Or until the model breaks down: when external factors intervene, another competitor appears, the market saturates, there's an antitrust lawsuit, technology changes, ...)

Thousand Small Sanities

Adam Gopnik – staff writer at the New Yorker, Canadian by birth, intelligent and articulate person – has written a lovely and thoughtful and frustratingly disorganized book about politics: A Thousand Small Sanities: the Moral Adventure of Liberalism.

Bottom line? Perhaps the need to be like a rhinoceros rather than a unicorn, to mention one of Gopnik's many metaphors. The world is complex and imperfect, humans are fallible, stuff happens, and we have to keep trying to do better. It's important to recognize more than one side of every issue, acknowledge limitations, and have empathy for others. Sharing is nicer than hoarding. Absolutism, on either Left or Right, brings trouble. "Grown-up people can count to two."

There's goodness aplenty in A Thousand Small Sanities – glittering asides, philosophical allusions, captivating mini-profiles of John Stuart Mill and Harriet Taylor, George Eliot and George Lewes, Adam Smith and David Hume, Charles Darwin, Michel de Montaigne, and many more. What there isn't, alas, is much structure to the arguments. Maybe that's a self-referential meta-comment on "liberalism" itself? More likely it's a sign of passion on the author's part (or haste on the publisher's). An index in the back and a roadmap in the front might have made the book more practical, though less poetic. A modern On Liberty it's not.

LOOPY - Pachinko Probability Distribution

http://zhurnaly.com/images/LOOPY/LOOPY_Pascal-triangle_pachinko_2012-08-29.jpg

Consider a simplified pachinko-like pinball machine: drop a ball at the top of the pyramid, and give it a 50-50 chance of ricocheting left or right as it descends. By the time it gets to the bottom it likely will be somewhere near the middle – but not always. This LOOPY model simulates the situation. As the lines on the "Variable Dynamics" graph show, probability starts out concentrated in the center and diffuses outward to form a Pascal's Triangle shape, 1-4-6-4-1 in the case of four layers. In probability that's called a Binomial Distribution and describes how to combine independent identical choices, like tossing four coins. If you flip them 16 times, on the average you'll get all heads once, three heads plus a tail four times, two heads and two tails six times, etc. 1-4-6-4-1!

http://zhurnaly.com/images/LOOPY/LOOPY_foxes-rabbits-grass_2021-08-22.png

Grass grows. Rabbits eat grass and make more rabbits. Foxes thrive by eating rabbits. And, after a while, rabbits and foxes get old and die. A super-simple Systems Thinking model exhibits fascinating behavior! Populations rise and fall, lagging each other in their cycles, gradually increasing over time. This Foxes-Rabbits-Grass simulation is included in LOOPY under the "Models" menu. Play with it, change the weights on the arrows or the starting values of the nodes, and see what happens!

LOOPY - Throw a Ball

http://zhurnaly.com/images/LOOPY/LOOPY_throw-a-ball_2021-08-17.pngThrow a ball up – it rises and falls, along a parabolic arc. Throw a ball faster and it goes farther and higher. Why?

Hint: gravity (red node) pulls downward (minus sign on the arrow) at a constant rate, so vertical velocity (green node) decreases at a constant rate; horizontal velocity (not shown) is constant; and a ball's position changes moment-by-moment proportional to its velocity. Hmmmm, now you know Calculus!

http://zhurnaly.com/images/walk/BFFs_heart-shaped_leaf.jpg"Three Unicorns!" 🦄 🦄 🦄 Top rating for a Saturday adventure ramble, starting at sunrise from Fletchers Cove. Head downstream on the CCT to Georgetown for coffee, alternating minutes to jog and recover. On the waterfront a pigeon walks the meditative labyrinth. A heart-shaped leaf says it all.

"This isn't TOO illegal!" The Palisades Trolley Trail is closed at its southwest end, but big holes in fences allow cut-through access to the Glover-Archbold Trail. 🔥 remembers running it decades ago. Reservoir Rd leads to a tony-historic Foxhall neighborhood. A dog-walker offers directions and points out the difference between "Q Place" and "Q St". After several short-cuts (!) into dead-ends, plus a stroll through the Georgetown Day School grounds, we re-encounter her at the trailhead she tried to direct us to!

"Acts of service for others are really gifts to Yourself!" Philosophy goes meta, with discussion of the "Individuation" superpower-strength (seeing uniqueness in all individuals) and the lure of one-upsmanship. Banter is strong: "I'm an open book!" – "Ah, that's the impression that you give so masterfully!" – "Don't even think of apologizing for being late!" – "I wasn't!"

Back on the Palisades Trail narrow openings in underbrush lead past lovely multi-million-dollar homes via rugged byways, stream crossings, rocks and roots, a trip-and-fall (no harm!), and the Glass Forest art installation. Heat and humidity make for dehydration; cool Gatorade from the bait shop is welcome. Debate who pays: "Oooh, now you're playing one of my own cards on me! You win, I must accept your gift graciously." Thank goodness for good friends!

Irrational Exuberance

Professor (and Nobel Memorial Prize in Economics winner, 2013) Robert Shiller's book Irrational Exuberance (originally 2000, with newer versions in 2005 and 2015) does a methodical job of exploring psychological factors behind market "bubbles", mainly focusing on corporate stocks and housing prices. From the preface to the second edition:

... this book [is] about trying to understand the change in thinking of the people whose actions ultimately drive the markets. It is about the psychology of speculation, about the feedback mechanism that intensifies this psychology, about herd behavior that can spread through millions or even billions of people, and about the implications of such behavior for the economy and for our lives. Although the book originally focused directly on current economic events, it was, and is, about how errors of human judgment can infect even the smartest people, thanks to overconfidence, lack of attention to details, and excessive trust in the judgments of others, stemming from a failure to understand that others are not making independent judgments but are themselves following still others—the blind leading the blind.

Shiller wisely points out the dangers of paying excessive attention to market fluctuations, of distrusting social institutions, of imagining that one can become wealthy without work, and of failing to "make conservative preparations for possible bad outcomes." He also warns in the preface to the first edition:

If we exaggerate the present and future value of the stock market, then as a society we may invest too much in business start-ups and expansions, and too little in infrastructure, education, and other forms of human capital. If we think the market is worth more than it really is, we may become complacent in funding our pension plans, in maintaining our savings rate, in legislating an improved Social Security system, and in providing other forms of social insurance. We might also lose the opportunity to use our expanding finanial technology to devise new solutions to the genuine risks—to our homes, cities, and livelihoods—that we face.

Shiller's bottom line, also in the original preface:

Most investors also seem to view the stock market as a force of nature unto itself. They do not fully realize that they themselves, as a group, determine the level of the market. And they underestimate how similar to their own thinking is that of other investors. Many individual investors think that institutional investors dominate the market and that these "smart money" investors have sophisticated models to understand prices—superior knowledge. Little do they know that most institutional investors are, by and large, equally clueless about the level of the market. In short, the price level is driven to a certain extent by a self-fulfilling prophecy based on similar hunches held by a vast cross-section of large and small investors and reinforced by news media that are often content to ratify this investor-induced conventional wisdom.

... all excellent cautions, especially in the current environment of extremely high stock market prices compared to corporate earnings!

Live in the World with Grace

From "They Used the Bible to Attack Her. She Used the Bible to Forgive Them." by Jennifer Finney Boylan, an essay about Susan Stanton, the former Largo Florida city manager who was attacked and fired in 2007 for being transgender:

Boylan writes, "... Admitting to past wrongs can help us move forward, and can keep us from being consumed by loss and hatred. But forgiveness doesn't mean that the past did not happen, or that the harm that was once done to us – or that we have done – has disappeared. In the end, it may be that forgiveness is best understood as an ongoing effort, part of a lifelong practice of trying to live in the world with grace. ..."

Cup Full of Love

A beautiful-wise metaphor:

You are holding a cup of coffee when someone comes along and bumps into you or shakes your arm, making you spill your coffee everywhere.

Why did you spill the coffee? "Because someone bumped into me!" Wrong answer.

You spilled the coffee because there was coffee in your cup.

Had there been tea in the cup, you would have spilled tea.

Whatever is inside the cup is what will spill out.

Therefore, when life comes along and shakes you (which will happen), whatever is inside you will come out. It's easy to fake it, until you get rattled.

So we have to ask ourselves: "What's in my cup?"

When life gets tough, what spills over?

Joy, gratefulness, peace, and humility?

Anger, bitterness, harsh words, and reactions?

Life provides the cup. You choose how to fill it.

Today, let's work towards filling our cups with gratitude, forgiveness, joy, words of affirmation, kindness, gentleness, and love for others.

The Year 2000

Leonard Richardson is a writer, software developer, and thoughtful person. Among many intriguing things in his blog is a 2008 analysis he made of predictions in the 1967 book The Year 2000: A Framework for Speculation on the Next Thirty-Three Years by Herman Kahn and A. J. Wiener. That book seems fascinating, methodologically if not for its content – and even more important is to look back at its predictions and see how they hold up a few decades later. Richardson does that, subjectively and entertainingly. He finds that "Out of 135 predictions there are 27 hits and 22 partial hits", with the 27 "hits" being (fixing a few typos, and hmmmm, there seem to be only 26 "hits"):

The failed "predictions" are also interesting. Many involve things that do (or could) exist but cost too much for widespread application. Others could arguably be true, but were written so vaguely that in Richardson's judgment they shouldn't count. Fascinating!

Power of Intention

From A Morning Cup of Yoga, Jane Goad Trechsel thoughts on the value of aspiration:

... Intentions have great power. We all get off track and lose the path we want to be on. If we keep coming back to our intention, eventually the road will go that way. Here are some sample intentions, but you will know what your heart yearns for.

... and intentions need not become narrow goals to cling to!

The study uses three dozen questions to provoke the sharing of ideas and experiences. It was recently described in an abridged form in [1] and half a dozen years ago in [2] and [3]. The questions are quite fascinating:

Set I

1. Given the choice of anyone in the world, whom would you want as a dinner guest?
2. Would you like to be famous? In what way?
3. Before making a telephone call, do you ever rehearse what you are going to say? Why?
4. What would constitute a "perfect" day for you?
5. When did you last sing to yourself? To someone else?
6. If you were able to live to the age of 90 and retain either the mind or body of a 30-year-old for the last 60 years of your life, which would you want?
7. Do you have a secret hunch about how you will die?
8. Name three things you and your partner appear to have in common.
9. For what in your life do you feel most grateful?
10. If you could change anything about the way you were raised, what would it be?
11. Take four minutes and tell your partner your life story in as much detail as possible.
12. If you could wake up tomorrow having gained any one quality or ability, what would it be?

Set II

13. If a crystal ball could tell you the truth about yourself, your life, the future or anything else, what would you want to know?
14. Is there something that you've dreamed of doing for a long time? Why haven't you done it?
15. What is the greatest accomplishment of your life?
16. What do you value most in a friendship?
17. What is your most treasured memory?
18. What is your most terrible memory?
19. If you knew that in one year you would die suddenly, would you change anything about the way you are now living? Why?
20. What does friendship mean to you?
21. What roles do love and affection play in your life?
22. Alternate sharing something you consider a positive characteristic of your partner. Share a total of 5 items.
23. How close and warm is your family? Do you feel your childhood was happier than most other people's?
24. How do you feel about your relationship with your mother?

Set III

25. Make three true "we" statements each. For instance, "We are both in this room feeling ..."
26. Complete this sentence: "I wish I had someone with whom I could share ..."
27. If you were going to become a close friend with your partner, please share what would be important for him or her to know.
28. Tell your partner what you like about them; be very honest this time, saying things that you might not say to someone you've just met.
29. Share with your partner an embarrassing moment in your life.
30. When did you last cry in front of another person? By yourself?
31. Tell your partner something that you like about them already.
32. What, if anything, is too serious to be joked about?
33. If you were to die this evening with no opportunity to communicate with anyone, what would you most regret not having told someone? Why haven't you told them yet?
34. Your house, containing everything you own, catches fire. After saving your loved ones and pets, you have time to safely make a final dash to save any one item. What would it be? Why?
35. Of all the people in your family, whose death would you find most disturbing? Why?
36. Share a personal problem and ask your partner's advice on how he or she might handle it. Also, ask your partner to reflect back to you how you seem to be feeling about the problem you have chosen.

... and the best answer to many of these is, perhaps, "I don't know!"

2021-06-25 - Sligo Survey

~3.4 mi @ ~13.4 min/mi

"Can you run any slower?" 🐻y asks a question with many interpretations! He starts behind 🤖 and catches up after a mile. Sligo Creek Parkway is closed to cars late Friday and the lanes are wide; nevertheless a hasty cyclist almost collides with a walker. Crepuscular creatures are out early as sunset shines final beams on an alabaster statue of the Virgin Mary overlooking the valley.

2021-06-24 - Spit Take

~3.7 mi @ ~14.2 min/mi

"Max Scherzer was right!" says 🤖. Spitballs are tough; spitting requires practice. Ditto hill climbs, as two repeats on Belvedere Blvd remind. 🐻y joins to survey Sligo Creek Trail: no turtles or geese on Friday's Eve, but lots of runners. After a mile together the twins part ways. 30-40 seconds of jogging with 90 second walk breaks makes a sinusoidal pace graph.

2021-06-22 - Bunny Bunny Ears

~4.4 mi @ ~13.7 min/mi

"Child, come over here. Do you have a cigarette?" asks an elderly lady on the front steps of an apartment building. Tuesday afternoon's Takoma trek leads to DC's Calvin Coolidge Senior High School track, where a football team practices pushing heavy objects across the turf. A lap in lane 7 at ~10.0 min/mi pace amuses the onlookers. Lawn art features a big wooden bird guarding its nest and a bunny doing bunny-ears behind another bunny.http://zhurnaly.com/images/walk/Bunny-bunny-ears_DC_2021-06-22.jpg

Morning Cup of Yoga

Jane Goad Trechsel in A Morning Cup of Yoga (2002) writes about how yoga helped her "... generally settle down and become calmer, less judgmental, and less caught up in the little dramas of life." She emphasizes liberation and optimism:

... I learned that when the negative voice inside said, "I can't do this!" another, wiser voice could say instead, "This looks difficult. What part of it can I do?" This was a completely different attitude, which freed me to try anything. ...

... and focuses on possibility, awareness, joy in the present:

... Stand quietly, appreciating the gentle, natural flowing rhythm of your breath and what your body could do today. When at last you open your eyes, let them be soft and settled back into the skull, so that you look out at the world from a deep place within. Open your ears and allow hearing, noting the various sounds that arise and pass away. Experience the world directly.

You may occasionally experience brief moments of absolute stillness and peace, feeling yourself at home in your body and at home with your breath, in the safe harbor of your deepest self.

... beautiful wisdom!

2021-06-20 - Rabbit, Meet Track

~9.3 mi @ ~17.9 min/mi

Barry and Kerry at Silver Spring International Middle School"A fellow Glaswegian javelin-thrower tried out for the US Olympic team last week," 🐻y reports on a steamy Sunday morning, and reminisces about legendary Hayward Field where he finished a marathon a few years ago. Some runner-dude named "Prefontaine" reputedly did shorter distances there, for some coach-dude named "Bowerman". 🐻y leads 🔥 down Sligo Creek Trail to the middle school for an anticipatory victory lap in his Missoula Virtual Half. 🤖 follows the duo, diverting to test a water fountain and then finding a short-cut to arrive first.
At sunrise Strava's GPS awards 🔥 & 🤖 a free bonus mile inside Starbucks as they get iced coffee. They set their cups carefully on the bleacher steps before a 400m calibration circuit at the cushioned track. Much room for improvement! "Now i know how you and 🦖 felt when you were just starting to train and i was your 🐇", says 🤖.http://zhurnaly.com/images/run/Demonic_sundial_2021-06-20.jpg

2021-06-19 - Run from Roses

~1.0 mi @ ~14.0 min/mi & ~2.4 mi @ ~11.6 min/mi

"Water ahead! Less than a mile to go! Mostly downhill!" Crew at the aid station shout encouragement to participants in the woman-only MCRRC "Run for Roses" 5k race on Saturday morning. After they've passed by 🤖 helps pick up empty cups, takes down signs, and walks-jogs back to the start-finish area. A few late cicadas flit, and another six-legged friend helps with data entry on a club computer.

"WARNING: Do Not Eat Infill Mix in Artificial Turf as It May Be Harmful to Your Health!" cautions the sign at Blair High School football field that evening. At the cushioned track 6 x 400m intervals flow, thanks to clouds and breezes and a few light raindrops, with robins and wrens watching from the grass. Miniature Eiffel Tower, Great Pyramid, Washington Monument, and Gateway Arch decorate an outdoor dining area. College amateur baseball is the post-run cooldown.

Best Frever

Silly slang shared almost a decade ago:

Best Frever

... cited in the "Urban Dictionary" as Best Frever:

What you call someone who's not your friEND (because even friEND has an end to it), but a person that will be there for you forever (because forever doesnt end in END). A person that is like your sister/brother, not someone that will stop being there for you when you're out of high school or college, but someone who will continue to be there for you forever. "You're not my best friEND, you're my best frever."

Traffic backs up along Arcola Ave as 🤖 jogs 30 seconds and walks 90 seconds on a Taco Tuesday afternoon mission: deliver letters to #1 Son! A turtle family suns itself on a log in Pine Lake.

"Crow!" - "Owl!" - "Tiny Loch Ness Monster!" - 🦘spies the first two perched nearby during the first mile of a Saturday dawn walk. 🤖 notes the last on the surface of Lake Needwood, neck curved S-shape. Then it turns into a cormorant and takes off. Hmmmm! The platform in the center of a playground web tips and pours rainwater as someone attempts a climb. Oops!

"No, just marathons and halfs!" An hour later, 🦀 disavows any plans to do ultras; 🐻 & 🤖 suggest reconsideration. The longer the run, the nicer the people! Bethesda Outdoor Pool parking lot is full on Saturday morning as swim team activities recommence. A happy meander northward encounters sporty wheels and arty fountain sculpture.

"Was that thunder, or my stomach?" Thursday late-afternoon rain brings puddles to the old middle-school asphalt track. A grounds-keeper shovels mud off the long-jump path and then, to the smell of gasoline, wields a weed-whacker and trims the baseball field border. A young runner does sit-ups on the bleachers between sprints. A couple shares one umbrella as they walk laps. Four soggy 400m intervals at ~9 min/mi pace pre-atone for gyros and pizza.

Flippant banter flows fast as 🥃 & 🐻 & 🤖 walk/trot along Rock Creek, joined by 🫕 in a happy-fortuitous encounter. At the turnaround a sign announces the end of Closure – which in psychology means the urge for sure answers and the fear of ambiguity. Maybe, or maybe not? Zen suggests: "Not Always So!"
