2019-10-04 - Ask Nature

~5.0 mi @ ~14.4 min/mi

"She's like Stephen Hawking!" Roadkill comments to Keymaster about how K2 simply smiles and listens as the kids debate philosophy, science, and Truth. ("Ask Nature!" said Hawking - cf Question Authority) Dawn Patrol sips coffee and rambles through Pimmit Hills while Rayleigh scattering subtracts shorter-wavelength photons to paint an amber sunrise.

"Hmmmm, 'Extremely constant'?" Keymaster ponders an oxymoronic phrase. We tread cautiously through the woods to Olney Park. No tripping on rocks or roots, please, with multiple marathons on the calendar for the coming weeks! How can the output of a neural network be properly interpreted as a probability? And how can hyper-busy end-users learn to use that information properly in their work?

"A crossing guard was posted here for Roadkill!" notes K2 when the friendly construction worker holds up her stop sign and blocks traffic just for us near the Metro. We analyze denial-of-service attacks and the tricky balance between trust and vulnerability, security and availability.

Ten Common Statistical Mistakes

"Ten common statistical mistakes to watch out for when writing or reviewing a manuscript" (by Tamar Makin and Jean-Jacques Orban de Xivry, 9 Oct 2019) suggests a set of pitfalls to beware of. Their abstract summarizes:

Inspired by broader efforts to make the conclusions of scientific research more robust, we have compiled a list of some of the most common statistical mistakes that appear in the scientific literature. The mistakes have their origins in ineffective experimental designs, inappropriate analyses and/or flawed reasoning. We provide advice on how authors, reviewers and readers can identify and resolve these mistakes and, we hope, avoid them in the future.

And in brief, their list:

... for any studies looking at the effect of an experimental manipulation on a variable over time, it is crucial to compare the effect of this experimental manipulation with the effect of a control manipulation. ...

... rather than running two separate tests, it is essential to use one statistical test to compare the two effects ...

... If a study aims to understand group effects, then the unit of analysis should reflect the variance across subjects, not within subjects. ...

... Spurious correlations most commonly arise if one or several outliers are present for one of the two variables. ...

... When a sample size is small, one can only detect large effects, thereby leaving high uncertainty around the estimate of the true effect size and leading to an overestimation of the actual effect size ...

... recycling the same data to first characterise the test variables and then to make statistical inferences from them, and is thus often referred to as 'double dipping' ...

... the more variation in one's analysis pipeline, the greater the likelihood that observed effects are not genuine ...

... When performed with frequentist statistics, conducting multiple comparisons during exploratory analysis can have profound consequences for the interpretation of significant finding ...

... a non-significant p-value does not distinguish between the lack of an effect due to the effect being objectively absent (contradictory evidence to the hypothesis) or due to the insensitivity of the data to enable to the researchers to rigorously evaluate the prediction (e.g. due to lack of statistical power, inappropriate experimental design, etc.). In simple words - non-significant effects could literally mean very different things - a true null result, an underpowered genuine effect, or an ambiguous effect ...

... Just because variability of two variables seems to linearly co-occur does not necessarily mean that there is a causal relationship between them, even if such an association is plausible. For example, a significant correlation observed between annual chocolate consumption and number of Nobel laureates for different countries (r(20)=.79; p<0.001) has led to the (incorrect) suggestion that chocolate intake provides nutritional ground for sprouting Nobel laureates ...

2019-10-02 - Youth of Athens

~6.1 mi @ ~14.5 min/mi

"You need a new trail name!" K-Rex declares, when Roadkill refrains from crawling through a web of yellow caution tape at the entrance to Lewinsville Park. Signs warn that the pedestrian bridge is under construction, and pre-sunrise darkness makes the creek invisible within the dense woods. So why this sudden display of common sense? Some mysteries may never be explained. At McLean High School's track Dawn Patrol is again stymied, this time by a chained-shut padlocked fence. But "... neither snow, nor rain, nor heat, nor gloom of night can stay" the quest for caffeine. K2 leads the way to a neighborhood cut-through. Keymaster explains category-theoretic issues of monoids and functors.

"We have corrupted the Youth of Athens!" declares Roadkill during the return trek from Starbucks, not realizing that Keymaster's alma mater is Ohio University in Athens. Management and Labor take turns covering ears to avoid overhearing each other. Can quantum mechanics explain the mind-matter problem? Are we going to slip and fall on the walnuts that bestrew the ground? Unanswered questions abound on a warm and humid morn. A super-speedy bunny sprints across a lawn.

"Ooops!" In the porta-john, just before the race, new shorts reveal a design problem: Roadkill's cellphone slips out and falls into, uh, ...

"No worries!" Fortunately the phone is in a zip-lock plastic bag; it lands on top of a pile of relatively-clean toilet paper; the hole isn't deep; and there's ample hand sanitizer in the dispenser. Whew! Drs M&M pose for the obligatory back-of-the-pack birthday selfie as starting-line crowds gather.

Category Theory and Minds

From a fascinating 2019 interview with Adam Gordon Bell — "Category Theory is in our minds? Bartosz Milewski weighs in." — as presented by John Walker, comments by Milewski:

... I think mathematics is something that is inherent to human beings. This is the only way we can deal with our environment because we have small brains. It's like, compared to the size of the universe, this is just like a tiny, tiny thing. And it evolved from apes that were trying to solve problems, like how to run away from a predator or how to kill an animal and eat it, start a fire, and so on. So the way we deal with complexity is by dividing into smaller tasks, solving them and then recombining the solutions. And that's what we do with everything. ...

and near the end:

... We always think that like we already understand 99% of stuff and there's this 1% missing. And I think this is completely wrong. We understand the 0.001% if that even makes sense, right? And there's so much stuff missing if we just ignore the stuff that we don't understand. ...

and:

... physicists are very pragmatic, you know; if it works, it works. Okay. If I can calculate something and then test it, then it's great. In this way, physicists are more like programmers. If it works let's ship it. ...

and completely separately from Bartosz Milewski's blog on 9 October 2019:

In category theory, as in life, you spend half of your time trying to forget things, and half of the time trying to recover them. A morphism, the basic building block of every category, is like a defective isomorphism. It maps the initial state to the final state, but it provides no guarantees that you can recover the original. But it seems like this lossiness is what makes morphisms useful.

There are people who can memorize mathematical formulas perfectly but have no idea what they mean. And there are those who get just the gist of it, but can derive the rest when needed. Somehow understanding is related to lossy compression.

We can't recover lost information. Once it's gone, it's gone. All we can do is to try to figure out what the original might have been like. In fact, knowing how the information was lost, we might be able to generate all possible inputs that could have led to a given output. It's the closest we can get to inverting the uninvertible. This is the main idea behind fibrations.

Let me illustrate this concept with an example. Consider the function ...

Six Secrets of Intelligence

A preview-review of The Six Secrets of Intelligence by Craig Adams, due out late 2019, gives away the "secrets":

... all obviously important, albeit as listed neither as orthogonal nor as complete as one might hope. Online sample text suggests a chatty, preachy book that begins with Aristotle and educational history, then turns to a discussion of the "Six Secrets" with examples from current events, followed by sections on psychology, philosophy, education, and society. Reviewer Arlene Holmes-Henderson rates it "... light on cognitive science, but it does provide a toolkit for analysing political debates and philosophical discussions ...".

Good enough — but why not take the time to provide a proper summary, a solid structure with bottom-line-up-front (BLUF) takeaways? And how about a well-designed framework for the "Secrets", making their interrelationships and dependencies and hierarchical relationships clear, memorable, and useful?

"Thinking Better" techniques should be applied to teach better thinking. As category theorist Eugenia Cheng notes in a mathematical context:

To study the world abstractly you use science; to study science abstractly you use math; to study math abstractly you use category theory. Each step is a further level of abstraction. But to study category theory abstractly you use category theory.

Ditto mind and metacognition ...

Keymaster reports on experiments with new gear, the perils of dehydration, and an overheated weekend runner found fallen on the W&OD Trail; a local rescue squad came to assist.

flowers in front of a Tysons Corner condo complex"Don't let Roadkill be roadkill!" K2 saves a life (again!) as she holds out an arm and calls for a pause before Dawn Patrol dashes across the highway. Today's trek stops mid-circuit for iced coffee from McD's. Traffic cones reserve a lane for the soon-to-begin Super H 5k in support of adaptive athletes; volunteer course marshals lounge roadside. Flowerbeds and lawn statues share loveliness with passers-by. Deer flick their white tails and retreat, or freeze to flare nostrils and stare.

"The Doctor is In!" Deep trail therapy today reveals the meaning of Life and solves the Hard Problem as well as all other issues. Hint: empathy is important. Ditto: non-judging, mindful self-care, and Being Here. Listening is good too. And appreciating beauty, as when sunbeams suddenly slice between trees during the misty sprint down a path between neighborhoods. Yes, and — despite hatred and injustice — there's so much to be thankful for in this amazing world. We're here to help each other. "Imagine all the people ...", as the song says.

"Gödel's Theorem basically says that once you go meta there's no end to it!" Roadkill digresses from monologuing about his personal woes to offer an Executive Summary of true-but-unprovable math and its connection to Turing's solution of the Entscheidungsproblem. Final miles are optimized — or rather, satisficed — and we get back in time to wish the family safe journeys. (Good morning, Katie-sensei!)

Four-Element Zen

Is there a significant metaphorical-mapping between the classical-mythic "Four Elements" and the awakening-awareness aspects of Attention + Acceptance + Affirmation? Maybe just symbol play-poetry:

... and if so, where then is Earth? — the foundational slow-solid-stolid substrate on which being-itself exists?

Perhaps this is just an amusing diversion, at most marginally useful in creative discovery of more patterns, or as a mnemonic device? (Or not!)

Georgia avenue train mural"How do you feel now?" Kind Sakurako checks frequently on Roadkill, who is recovering from a vertigo attack earlier this week. No falls today: he's ~80% back to normal. We set off in the darkness and practice a 1 minute run, 1 minute walk pace control regime. The one-lane wooden Grace Church bridge is closed for construction; the Acorn Park downtown provides a quick history lesson in the origins of "Silver Spring" (mica flecks in a water source).
Murals decorate the Georgia Avenue underpass at the train tracks. Sligo Creek takes us upstream past the Capital Beltway. A peachy sunrise lightens the horizon.Georgia avenue train mural
Georgia avenue train mural"Have you seen three old men nearby?" Sakurako and Roadkill rendezvous with Ken, Emaad, and Danger Man (aka "Gar" aka "Griz") after a near-miss, then continue northward. At University the trio proceed along the trail while S&R divert in search of sustenance. Starbucks' line is too long so bananas and a Slurpee from 7-11 must suffice.

Each annoying the other
    Each confirming and refuting the other

Although each would, like a child in a circus crowd,
    Be lost without the hand of the other.

"Right answer!" declares Roadkill, when a fellow runner says she's not training for anything special. The dash to General Getty Park is at 9.3 min/mi pace, after which Danger Man leads the way along Sligo Creek to the track. Feats of strength accompany a brisk 1:46 lap. At the elementary school a compass rose decorates the playground. Bronze eagles guard a gate. Curly calligraphic chalk commands "Joy". Yes!

"To the Virgins, to Make Much of Time?" Roadkill struggles to recall the source of the phrase "Time's wingéd chariot". He guesses Emily Dickinson or John Donne, neither of which is correct. (It's by Andrew Marvell, in the carpe diem poem "To His Coy Mistress".) Blisters on the left foot, twinges in the right - clearly more mileage and speedwork are needed!

Then it's Rock Creek Trail to Connecticut Ave, pause at another busy Starbucks in Chevy Chase for a pink drink, and proceed south to meet Danger Man. Hilly Leland St brings us to Bethesda, and then the Capital Crescent Trail to northwest DC. Vixen greets us as she zooms by. A path leads past the Dalecarlia water treatment plant.

"So where's the Historic Marker?" K2 shows us the first house she stayed in when she moved to DC for grad school three decades ago. Aromas of fresh bread and other delicacies drift from bakeries and kitchens along Yuma St NW. Beautiful impatiens form a waterfall of red-white-pink beside a front yard stairway. At a boundary stone on Western Avenue the crew stands behind bars.

Inside the new Starbucks a wild GPS glitch teleports Dawn Patrol a bonus 2.2 miles as we await caffeine. The new bridge over the Beltway is still closed to pedestrians - uh, officially, that is. On the other side Keymaster describes a "soft recommendation" he recently made that helped a decision maker. K2 and Roadkill offer gratuitous first-marathon advice for how to avert chafing on delicate body parts. The Trail Talk is strong in these ones!

Within the first block Roadkill glimpses a glint on the street, backtracks, and picks up a shiny dime. Profit! A passing runner confirms the W&OD Trail route. At sunrise we turn onto the Custis Trail, pause for coffee, then continue through Rosslyn to the Mount Vernon Trail. South of the airport fishermen cast lines into Four Mile Run. The path upstream takes us by Weenie Beenie and back onto the W&OD. Today's experiment in speed control works well: we run only brief segments, walk the hills, and still average ~13 min/mi overall.

"New England candymakers created sweet-brittle honeycomb bars like that," K2 reminisces, as Roadkill compares chocolate-coated Australian "Violet Crumbles" to British "Crunchies". New pack and new shoes work well, modulo minor chafing. Big mistake: poor hydration. Dizzy Roadkill belatedly quaffs a quart of Gatorade at mile 15, after which run-walk tactics between alternate power line poles close the loop. A beautiful bright butterfly-wing patterned running-skirt lures roving eyes. (Guess whose!) Trail talk covers organizational innovation, metacognitive methods, and food.

Five Great Joys in Life

From writer Robert Brockway, an insightful essay in, of all places, Cracked: "5 Great Joys in Life That Healthy People Never Experience" (June 2012). It begins:

I, like many of you, am a genetic wreck.

I am not supposed to be alive right now. If humanity still functioned on any sort of evolutionary logic, I would probably have a brief but successful career as a lion's afternoon entertainment, instead of being what I am now, which is a Mildly Successful Internet Thing. I possess a slew of health problems, chemical deficiencies, mental aberrations and spiritual monstrosities that I manage every day by the grace of medical science and an oblivious culture that not only tolerates but nurtures weakness (thanks, guys!).

Sometimes, I get bitter about my situation. I watch the powerful and healthy from afar, while I squat here in the damp shadows of disease, nurturing my resentment like a hypothyroid, myopic Gollum. But there are some joys in life that the hale, hearty, happy and healthy will never know ... the simple pleasure of ...

... and goes on to list Brockway's five great joys (here, omitting many Bad Words and Naughty Images):

  1. Getting New Glasses: "... You had no idea that life had better graphics available. You've been playing the 16-bit world this whole time, while everybody else was running quad-core realities hooked up to an HD screen. ..."
  2. Getting a Diagnosis: "... You're a problem that took all of medical science thousands of years to solve. ..."
  3. The Moment When the Medication Kicks In: "... If you're lucky enough to have a condition that can be treated -- not even cured, just treated a little -- the moment the medication kicks in is like unlocking a secret level in life. All these years, you've existed at half power ... If people thought you were obnoxious after you got those glasses, with your constant prattle about wood grain and cloud patterns, they're going to strangle that newfound health right out of you the first time you wake up to find it doesn't hurt as much as it usually does. ..."
  4. Getting Healthy: "... when you start off a pile of half-functioning organs and good intentions and it's only through years of slow, painful, careful work that you manage to shove yourself into a mold and come out looking something like a person -- you get a whole different outlook on life. ... You've barely bumped the needle on the Healthometer. But you're on there, now. And going from zero to one is an unfathomably larger distance than going from 1 to 100. ..."
  5. Backsliding: "... what's the upshot of getting worse? Experience. you're treading familiar ground. You know what failing health and disability are; you know what they feel like, and what it takes to get through it. That's a skill set you are guaranteed to use someday, because all of us, every one, will get sick and die eventually. That must be an awful experience for a healthy person -- being stuck in there, flailing in reverse down death mountain for the very first time. They will be wholly unprepared for it when it happens. But not you. ..."

Talk about Mr Pollyanna, and wise application of the metacognitive principles of reversal and reframing.

Awesome Optimism!

"What's in a name?" Roadkill quotes Alan Perlis, "The best book on programming for the layman is Alice in Wonderland, but that's because it's the best book on anything for the layman." Re name-value distinction, he cites a scene in Through the Looking-Glass:

' ... The name of the song is called "Haddock's Eyes." '
'Oh, that's the name of the song, is it?' Alice said, trying to feel interested.
'No, you don't understand,' the Knight said, looking a little vexed. 'That's what the name is called. The name really is "The Aged Aged Man." '
'Then I ought to have said "That's what the song is called"?' Alice corrected herself.
'No, you oughtn't: that's quite another thing! The song is called "Ways and Means": but that's only what it's called, you know!'
'Well, what is the song, then?' said Alice, who was by this time completely bewildered.
'I was coming to that,' the Knight said. 'The song really is "A-Sitting on a Gate": and the tune's my own invention.'

Tribal Leadership

Tribal Leadership: The Key To Building Great Teams by Dave Logan (with John King and Halee Fischer-Wright) is yet another easy-reading business storybook, focused on what many middling managers enjoy hearing and already believe (like Drive). It's hugely first-person, full of name-dropping anecdotes of semi-famous folks whom the authors interviewed and breathlessly quote. Negative evidence? Not much. Confounding factors? The rôle of luck? The value of self-criticism? Ditto.

The goodness of Tribal Leadership is important: think meta, as applied to levels of self-actualization for individuals and teams. A Busy Executive Summary (adapted from Michael Batko's notes and the Farnham Street blog) might be to see organizations in five stages:

Stage Themes Motto Characteristics
1Alienation & Hostility "Life Sucks"Gangs → the lowest form of culture, rarely encountered outside prison-like situations
2Separation & Apathy "My Life Sucks"Apathetic victims → "Other people's lives seem to be working, but mine sucks."
3Superiority & Heroism "I'm Great"Dyads and dominant-submissive relationships → "I'm great" with the unstated "and you're not"; people try to outperform one another on an individual basis and put one another down, often under a veil of humor; a lone warrior culture, the "wild, wild west"; trust must be earned
4Teaming & Pride "We're Great"Triads and values-based relationships → "We're great" with the unstated "and they aren't" (another tribe, company, competition); together, radiate tribal pride; trust is assumed
5Transcendence "Life is Great"Relationships with all whose values resonate → there is no "they"; Stage 5 cultures are history-making, so far ahead that competition is irrelevant, e.g., "We are defeating cancer", not "We want to be #1"

And then? As wise comrade "Alice" asks, What happens beyond Stage 5?

Maybe Oneness? Pure Being? Total Wonder?

Keymaster explains, "The goal was to blow a hot breeze through the tired anime industry." Dawn Patrol, feeling tired and hot, runs a few steps before settling into a stroll. We arrive at Starbucks only to discover it closed. Sad!

"Don't say 'Sorry', say 'Thank you for understanding!'" Roadkill chides an apologetic employee, locked out like us, when she begs forgiveness. The boss who holds the keys is nowhere to be found, over an hour late. A smiling construction worker is a helpful crossing guard as the decaf duo hikes back to work. Conversation covers the super-efficient SpaCy machine learning library and a critique of Dan Pink's business-motivation book Drive.

2019-09-02 - Mad Dog Zimmarathon Plus

~28.2 mi @ ~13.6 min/mi

"We used to be fast - now we enjoy!" Two ladies lead Roadkill for a segment of the 28-mile Mad Dog Zimmarathon-Plus reenactment on a soggy Labor Day morn. They tell of running Boston, chat about local courses, and turn back at KenGar to trek downstream. A pair of deer stand in the stream; a chipmunk scurries across the path.

"Today is an experiment," Roadkill explains. Adventure begins at dawn: take Rock Creek Trail to Lake Needwood, circumnavigate, and return, with selfie-pauses along the way. En route take four Succeed! electrolyte capsules, eat four Clif Shot gels, quaff two big bottles of Tailwind, and drink a couple of additional quarts of water. Grease feet, and get one blister, side of left big toe. No chafing except on back where singlet seam meets pack strap. New shorts with pockets work well. Fingers swell just a little. Left hip and hamstring ache slightly after a dozen miles. Vertigo minimal, ditto double vision. No stumbles or falls; lose only 4 pounds from dehydration. Overall verdict: despite oppressive humidity, feel great!

"Run 30 seconds or less, then walk!" Pace restraint is tough, but after a too-fast first mile splits settle into the 13-15 min/mi zone. Amble up hills; trot at most half a minute; pause at every water fountain. Hmmmm - will the same strategy of self-control work at marathons with dear friends during the next few months? Worth a try!
midway through the journey, Lake Needwood

Attention Means Attention

From Charlotte Joko Beck's talk "Attention Means Attention", quoted from Nothing Special: Living Zen in Tricycle magazine Fall 1993:

... every moment in life is absolute in itself. That's all there is. There is nothing other than this present moment; there is no past, there is no future; there is nothing but this. So when we don't pay attention to each little this, we miss the whole thing. And the contents of this can be anything. This can be straightening our sitting mats, chopping an onion, visiting someone we don't want to visit. It doesn't matter what the contents of the moment are; each moment is absolute. That's all there is, and all there ever will be. If we could totally pay attention, we would never be upset. If we're upset, it's axiomatic that we're not paying attention. If we miss not just one moment, but one moment after another, we're in trouble. ...

Drive

Dan Pink's book Drive: The Surprising Truth about What Motivates Us is another brick in the thick genre-wall of business-motivational tomes. It features some modern psychology and neuroscience — along with a lot of feel-good self-justification aimed at managers and executives. No need to pay people (beyond a fuzzily-undefined baseline); just give them "Autonomy" and "Purpose", let them seek and achieve "Mastery", and they will work hard for you. No need to cite evidence that disagrees with your hypothesis. No need for nuance.

That's a caricature of Drive, and it's unfortunately accurate. Pink focuses on folks who are successful, celebrities, the winners of the race, those who are already living in the nice neighborhood with the multi-car garage. There's not much thought given to those who fell short, and why they failed. Not much about assisting one another over rough patches, or about the need that everyone has for help when young or aged, ill or injured. We're all broken at one time or another, all need patching. There's not much charity or love in Drive.

And alas, there's the attempt to define new jargon, in the apparent hope that it will catch on and give the author a bit of extra stickiness, some enduring fame in the meme-o-sphere. Pink's proposed terminology isn't worth mentioning; it's derivative and unnecessary. For better science, try Ariely and Kahneman et al.

Momo

Momo (1973) is an extended parable about time and mindfulness by Michael Ende, author of The Neverending Story. The title character is a little homeless girl whose superpower is listening — and her listening catalyzes awakening for those around her. In the original German its full name is Momo oder Die seltsame Geschichte von den Zeit-Dieben und von dem Kind, das den Menschen die gestohlene Zeit zurückbrachte, which translates into English as, "Momo, or the strange story of the time-thieves and the child who brought the stolen time back to the people".

Evil cigar-smoking Grey Men take away time from human victims, who are left in helter-skelter unhappy busy-ness. With the help of a communicative tortoise and a mysterious time-master, Momo saves the world. It's a sweet story, allegorical and kind-hearted, rather preachy in places, rather important in its sermon. The translation is by J. Maxwell Brownjohn. In Chapter 12 ("Nowhere House") there's a lyrical passage that D B Davis on the discussion group rec.arts.sf.movies quotes as his favorite. It's the heart of Momo:

Everything was bathed in a sort of golden twilight.

When her eyes became accustomed to it, Momo saw that she was standing beneath a mighty dome as big as the vault of heaven itself, or so it seemed to her, and that the whole of this dome was made of the purest gold.

High overhead, in the very centre of the dome, was a circular opening through which a shaft of light fell straight on to an equally circular lake whose dark, smooth waters resembled a jet-black mirror.

Just above the surface, glittering in the shaft of light with the brilliance of a star, something was slowly and majestically moving back and forth. Momo saw that it was a gigantic pendulum, but one with no visible means of support. Apparently weightless, it soared and swooped above the mirror-smooth water with birdlike ease.

As the glittering pendulum slowly neared the edge of the lake, an enormous waterlily bud emerged from its dark depths. The closer the pendulum came, the wider it opened, until at last it lay full-blown on the surface.

Momo had never seen so exquisite a flower. It was composed of all the colours in the spectrum — brilliant colours such as Momo had never dreamed of. While the pendulum hovered above it, she became so absorbed in the spectacle that she forgot everything else. The scent alone seemed something she had always craved without knowing what it was.

But then, very slowly, the pendulum swung back, and as it did so Momo saw to her dismay that the glorious flower was beginning to wilt. Petal after petal dropped off and sank into the blackness below. To Momo, it was as if something unutterably dear to her were vanishing beyond recall.

By the time the pendulum reached the centre of the lake, the flower had completely disintegrated. At the moment, however, a new bud arose near the opposite shore, and as the pendulum drew nearer Momo saw that an even lovelier blossom was beginning to unfold. She walked around the lake to inspect it more closely.

This new flower was altogether different from its predecessor. Momo had never seen such colours before, but these colours seemed richer and more exquisite by far. The petals, too, gave off a different and far more delicious scent, and the longer Momo studied them the more marvelous in every detail she found them.

But again the glittering pendulum swung back, and as it did so the glorious blossom withered and sank, petal by petal, into the dark and unfathomable depths of the lake.

Slowly, very slowly, the pendulum proceeded on its way, but not to exactly the same place as before. This time it checked its swing a little way further along the shore, and there, one pace from where it had previously paused, another bud arose and unfolded.

To Momo this seemed the loveliest lily of all, the flower of flowers — a positive miracle. She could have wept aloud when this perfect blossom, too, began to fade and subside into the depths, but she remembered her promise to Professor Hora and uttered no sound.

Meanwhile, the pendulum had returned to the opposite shore, another pace further along, and a fresh bud broke the glassy surface.

As time went by, it dawned on Momo that each new blossom differed entirely from those that had gone before, and that it always seemed the most beautiful of all. She wandered around the lake watching flower after flower unfold and die.

Although she felt she would never tire of this spectacle, she gradually became aware of another marvel — one that had escaped her till now: she could not only see the shaft of light that streamed down from the centre of the dome; she could hear it as well.

At first it reminded her of wind whistling in distant treetops, but the sound swelled until it resembled the roar of a waterfall or the thunder of waves breaking on a rocky shore.

More and more clearly, Momo perceived that this mighty sound consisted of innumerable notes whose constant changes of pitch were forever weaving different harmonies. It was music, yet it was also something else. All at once, she recognized it as the faraway music she had sometimes faintly heard while listening to the silence of a starry night. ...

... a dreamlike vision of Life, unique and precious, transient and immortal.

Metacognitive Classroom

From August 2019's "5 ways to develop metacognition in your classroom" by Dr Tony Cotton:

  1. Generalize Narrow-Specific Questions: Understand the possibilities for learning: plan learning objectives that provide a range of possibilities for learning. Use "develop my understanding of equivalent fractions", rather than "write down 5 equivalent fractions for ¼ and ½."
  2. Link to Past Knowledge: Draw on prior knowledge: open lessons with activities that get students thinking and talking about what they already know. Ask them to work in pairs to find out what students know about a new topic before you start teaching it. Use this prior knowledge to plan next steps for learning.
  3. Be Open & Flexible During Learning: Monitor learning continually: limit the amount of time you spend talking to maximise students' time for discussion. Ask open questions to get extended responses and monitor these discussions for evidence of learning. For example, are they demonstrating critical questioning? Use this evidence to plan what comes next.
  4. Summarize What Was Learned at the End: Reflect on the learning that has taken place: don't just ask for answers, ask students to reflect on the learning process they took to come to their conclusions. Ask what they already knew and what they found challenging. Explore ways that students will be able to draw on this learning in the future.
  5. Capture Results: Develop a self-regulating classroom: use learning journals to support students in becoming independent, reflective learners. Ask them to write about what they've learnt. What did they find easy and what was challenging? What did they do when they were stuck? What helped them learn?

... and to eat our own cooking and be meta-meta, can we ask ourselves to execute the above 5 steps on this very discussion?

  1. how can we develop our understanding of metacognitive learning strategies?
  2. what do we already know about teaching metacognition?
  3. can we design adaptive real-time strategies to teach metacognition more effectively? (e.g., can the instructor practice constant systems-thinking during the learning-teaching process?)
  4. what have we now learned about teaching metacognition?
  5. how can we find this again some day?

(rather obviously for #5: write a ZhurnalyWiki page "Metacognitive Classroom"!)

before the start of the Habanero Hundred"You look like the kind of person who would do this crazy thing!" says a fellow runner at high noon with temps in the upper-90s & lower-100s. We're about to start the Habanero Hundred in east central Texas - though note that Roadkill is just doing the 10k single-lap option. Thank goodness, given mega-sunburn within 90 minutes!
After the first mile reality sets in and pace slows to a walk for most of the journey, with a faux-sprint to the finish line when people are watching. Eye-catching Texas flag gear abounds. The course meanders along horse trails through scrub brush land of the 7iL Ranch near Cat Spring. The owner, Faye, is friendly and helpful. She's in her 70s and tells of a Swiss "Zimmermann" great-grandparent. Since her father had only daughters, she got to do the herding, branding, castrating, etc.

Mega-kudos to DD/Keith & DSiL/Rita for cheering (and enabling) this humbling experiment in high heat and humidity; hats-off to Trail Racing Over Texas for its great management and attitude. Official 10k results: 25th place of 85 finishers, 90.1 minutes, first (and last!) over age 65, first (of 2!) from outside Texas.

Follow it, cross the creek at a narrow spot, and find a way to where a gravel road dips by a flood gauge. Trail talk includes the proof that any positive integer is the sum of four squares, how to transliterate Korean using finite state automata, and the risks of blow-drying a wet furry dog.

"Hi, Roadkill!" says Vixen as she dashes by. Small world, esp. on Saturday mornings when long training runs converge on the Georgetown DC waterfront. From Lock #10 on the C&O Canal, 0600 sharp, at K2's suggestion Dawn Patrol commences a quest for coffee. The towpath leads us downstream past deer, turtles, spiderwebs, great blue herons, ducks and ducklings, cardinals, and birds with scary-long-sharp beaks (a variety of heron?). The bright new mural on Water Street features JFK's "Ich bin ein Berliner" as well as "Liebe" (German for "Love") framed in roses.Georgetown mural Kennedy
Georgetown mural Kennedy"Today it's my turn to crash and burn!" Roadkill suffers (dehydration? old age? excess weight? can't be aftereffects of last night's track meet!) and is thankful for kind companions who tolerate his ever-lengthening walk breaks. Runners in a 5k race flow past. At Starbucks all call for tall iced - Coffee, Pink-Drink, and White-Tea-Guava-Lemonade - then share a fresh croissant. Très bien! Under the Whitehurst Freeway a lithe young runner stretches eye-catchingly; miles later, Roadkill blushes to remember. We analyze the recovery-meal merits of pizza vs ramen vs crayfish - not to mention Violet Crumbles!

"You may have just solved my problem!" At mile 14 K2 dictates a text message to her DH re the potential answer to an upholstery challenge. Keymaster tiptoes into new distance territory as his training ramps up toward an October marathon.

2019-08-02 - MCRRC Going Green 2 Miler

2.0 miles @ ~7:54 min/mi

MCRRC Going Green track meet - photo by Dan Reichmann"Thank you!" gasps the fast runner, surprised that Roadkill moves out to Lane 2 to let her pass on the inside. This evening's 2 mile race at Gaithersburg High School is slower than 2009-2012 (13:42 + 13:53 + 14:31 + 14:30) but faster than 2018 (16:08) — official time 15:48, good for 3rd of 5 in the male 65-69 age group, and overall 84th of 125 finishers. If 20 pounds lighter, would Roadkill be 80 seconds faster?

Friendly arch-rivals Tom & Igor opt for earlier & later heats, respectively. Photos by the inimitable Reichmanns; finger positions by Roadkill encode in binary the lap count.

2019-08-02 - Change for the Better

~5.7 mi @ ~14.1 min/mi

"Your cooking has begun to get better!" K-Rex recounts her son's latest compliment. Lightning flickers behind clouds in the west. "Ask him whether the cooking has changed, or if he has?" suggests Roadkill. Dawn Patrol dashes south to Starbucks on a warm and humid morning.

"After almost every acronym, they pause to ask 'Do you know what that means?'" K2 is happy that people briefing her are confident (and wise) enough to check. Raindrops begin to fall. Keymaster reports that he is mentoring a new young person. Roadkill approves: "You will learn much from her!"

2019-07-31 - Shiva Stories

~5.1 mi @ ~14.6 min/mi

"Don't worry, I know where the 30 horses are!" says somebody who comes to console a friend of Dawn Patrol sitting shiva. Apparently the recently-departed had a secret business — in fact, more than one. "Don't worry, I know where the meat truck is!" says another mourner. And separately from yet another visitor, "Don't worry, I'm the truck driver!" Perhaps life really is like the films Death at a Funeral and Eulogy? A humid morning sky is pumpkin-tinged as we take cut-throughs to Starbucks, quaff caffeine, and close the loop in time for early meetings.

Philosophy Now

The magazine "Philosophy Now" seems by turns provocative, silly, and deep; it features diverse, short, highly-readable articles with cute, mostly-relevant illustrations. Particularly valuable are essays that explore useful terms for important concepts (e.g, "promiscuous realism" in an interview with John Dupré, and the unfolding of theodicy in "The Good, The Bad and Theodicy"). Philosophy Now helps readers think, and especially to:

2019-07-29 - Leave No One Behind

~5.1 mi @ ~13.4 min/mi

"Abandon you? What do you mean? This is Dawn Patrol — we leave no one behind!" Yeah, somebody's sick, got no sleep last night, has a long day ahead, and then apologizes for cutting today's trek slightly short? No way! "Next time tell us right at the start — so we can mock you for the entire run, not just the final mile!"

"You want a tall hot blonde?" At Starbucks Roadkill confirms Keymaster's coffee order; K2 opts for iced. We circle Tysons, consider drawing a GPS trackfile image of spectacles or a bow tie, but defer that until another day. Reports of weekend activities include upholstering a headboard and showing tourist attractions to out-of-town friends. And, of course, running ...

2019-07-28 - Riley's Rumble Half Marathon

~13.1 mi @ ~9.6 min/mi

happy ice water at mile 10 - photo by Bridget Fox"Must ... resist ... temptation ...", says Roadkill at mile ~3 where runners turn back for the 8k option. Butterflies flit among flowers; corn stands tall in the fields. Temperatures are in the 70s, unusually cool for the Riley's Rumble half marathon.

"Go Roadkill!" Vixen cheers. Her photo at the mile 10 aid station captures a moment of joy, as runners sips ice water before facing the final climbs on a hilly course.

Preliminary results: 217th place of 506 finishers, 5th of 14 in the 65-69 year old male cohort, chip time 2:05:24 (gun time 2:05:40). Mile splits, roughly corrected for GPS error: 8.5 + 9.2 + 9.3 + 9.3 + 10.0 + 9.6 + 9.6 + 10.4 + 9.9 + 9.4 + 9.6 + 10.4 + 10.3 minutes, plus a sprint for the final fraction.

S.P.Q.R.

Prof Mary Beard's history S. P. Q. R., offers a well-written large-scale systems view of ancient Rome that refuses to be distracted by ephemeral events, crazy-Emperor anecdotes, or just-so storytelling. Beard frames her analysis with discussions of citizenship and how it grew to finally include all residents in the territories controlled by the Empire. She turns a critical eye toward ambiguous evidence and presents alternative explanations when appropriate — a multidimensional view of a civilization, unlike the monocular squint that some of her critics offer. SPQR is especially valuable for the concepts and metaphors it offers, many of which illuminate other societies including our own.

2019-07-27 - Les Macarons

~4.9 @ 13.1 min/mi

"And I didn't say a word to him for two days!" K2 tells of an expired-passport misadventure that, in retrospect 25 years later, turned out ok. R2 describes law students in panic mode about upcoming bar exams. Sakurako explains the black compression apparatus around her legs after last weekend's run. We loop through downtown Bethesda, then take an out-and-back along the Capital Crescent Trail. Upon return Roadkill passes the torch to Danger Man. At Paul, the French bakery, les macarons sont exquis.
