On the last day of school, a student confides "I have a gift for you but I forgot it at home!"
I say, half-joking, "Well, you know where I live so you can just drop it off sometime." (I live in town and not too far from this student).
She says "Okay -maybe I will."
Yesterday she emails me to see if someone will be home today so she can drop it off.
This afternoon, my parents and I go out for a walk and this student happens to be driving to my house to drop off the gift. Seeing me, she stops, jumps out and hands me a gift. Then she jumps back in her car and drives off.
Hours later, Isabelle comes home and sees my unwrapped gift:
"Hey, where did this cool book come from?"
Before I can explain, my Mom pipes up, "When your Dad walks around town, people just stop their cars and give him gifts in the middle of the street."
I pause for a second and then say, "Yes, that's exactly correct."

This is what you get...
... when you show "My Dinner with Andre" to some students.
Student Council ran a charity fund raiser in which you buy a cup for hot chocolate and write a message of kindness/support on it. The cups are delivered and then you use the cups during lunch to score your hot chocolate gift. One of mine read as follows:
Rather than use it for a drink, I taped it up on my desk to remind me to appreciate the simple pleasures in life.
Thanks, ML (with sidekick AC)!

Dilbert, Sales, and Teaching
I was listening to an interview with the creator of the Dilbert comic, and he was talking about how he changed the comic to please his readers and then experienced blow-out success. His contrast of how traditional artists don't do this whereas it is a core idea of sales reminded me of Dan Brown talking about how he followed a similar formula in writing his block buster novels (short, easy-to-digest chapters; unchallenging plotting & characters; easy enough mystery that his readers can feel smart solving on their own, etc.). Although this idea of the difference between the "pure" artist creating the art for art sakes versus the more crass "I want to be popular, give 'em what they want" entertainer is nothing new, I found myself thinking about education.
There is constant pressure to do evidence-based teaching strategies that often fall flat in class: project-based, flipped classes, individualized course-of-studies, authentic real-word ambiguous problem solving, purposefully exploring misconceptions, actively constructing & testing models, etc. Why don't we teachers do more of these things in the face of the evidence that learning outcomes frequently improve when we make the learning harder? Part of the answer is that we can not afford to be artists; we are actual more on the salesman end of the spectrum. If the students are unhappy (or we are unhappy) then the effort is doomed.
The first song you hear on the radio should not be challenging to parse if you want to start liking music. The first painting you appreciated probably was just a nice scene well executed. The first book you read cover to cover was probably more fun than deep.
Education is more Dan Brown than William Faulkner.
More Norman Rockwell than George Braque.
More Elton John than Nick Cave.
The trick, of course, is to serve the students some fried chicken but let them catch a whiff of coq au vin...

Hard of Hearing?
First there was the bald spot.
Then, the reading glasses.
Now, I can't hear right???
Today, at the end of a long meeting, the teacher on my left leaned forward and asked me, "Hey Ken - do you have any recommendations for a good Scootch Band?"
Now, I'm not usually so proud but for some reason I was really embarrassed that I have no idea what a Scootch Band is so I kind of hemmed and hawed, but eventually just admitted, "Sorry - I'm just so not with it, I have no idea what a Scootch Band is - I don't even know what the "Scootch" sound is..." (I was thinking some kind of reggae meets bluegrass kind of thing??)
As I turn my head in shame, she laughs and says, somewhat incredulously, "I asked if you have any favorite brands of Scotch. You know Scotch Whiskey? I need to buy someone a gift."
Oh boy... now it all made sense... a music teacher wouldn't normally ask me for a band recommendation, would they?
The fact that my fellow faculty members would ask me a whiskey recommendation is probably worthy of a whole blog post on its own...

Evolution, Dwelling, and Free Will
So, here we are with all this grey matter. We evolved all this ability to think through a whole lotta "what if's" in order to feed ourselves, take care of our tribe, and avoid those predators in the night. But, now, life doesn't offer us those existential threats so we invent our own. We dwell on some trivial detail. We keep ourselves up at night dwelling: "Why did my boss send that email?", "Why did I say the wrong thing to that person?" etc.
All that predisposition to use our brainpower to avoid life threats now squandered on trivialities of modern existence. I have, for years, found that very sad and would dwell on the negativity of this feeling about the modern condition. Woe is me. Woe is us! (Imagine the rebranding of Toys-R-Us as a store for existentialism: "Woes-R-Us"!)
Recently though, I had a bit of an epiphany. Why not turn that excess cognitive bandwidth over to dwelling on irrationally positive feelings? How lucky I was to catch my favorite song on the radio! How beautiful the snow on the naked tree limbs and that I have the time to stop, catch my breath, and admire this view! How wonderful that this student came by to share a personal story and we had a very real human-to-human moment in the midst of a very constructed and hectic school day!
It's like my favorite Bohr quote about Profound Truths: "A profound truth is one where the opposite of the statement is also true."
Modern life has provided space for me to dwell on and fret over the negative minutia.

A snowy day at the kids' dentist's office
The smell of the freshly fallen snow is unmatched
The white blanket covers all of life imperfections
The cleanliness of cold air is purity distilled,
Perfectionists rejoice.
The flowers and rains are earthy and funky
The colors and sprouts hint at possibilities
That funk hints at the life that spawns it,
Futurists hope.
The heat and humidity cloy and smother
Visible waves of heated air distorting vision
Introspectively wondering at our life’s course,
Philosophers ponder.
Hints of decay and drying vegetation tantalize
The variety of transitions intriguing in its potential
As the possibilities nested within choices manifest,
Dreamers dream.
Are there really Seasons?
Are there personality types?
Do things come in bins or do we organize them that way?
Isn’t life both quantum and continuous?
I shift from Dreamer to Philosopher to Whatever to Whoever,
Moment to moment.
Weather or a Season or Climate?
I am all those things and I am none of them.

Friends?
It took my son to convince me that stuffed animals can indeed be cute. I've been in denial by whole life but now, finally, I see the error of my ways...
Take good care of Hedgie, Opackway!

Participating or Protesting, Always a Nerd
This week is "Spirit Week" at the High School. It is a week designed to promote the kinds of things about high school that I avoided like the plague when I was a student: School Spirit, Class Consciousness, School Colors, Decorating the hallways, pep rallies, etc. (As an adult my feelings may or may not have evolved, depending on the actual activity and my degree of snarkiness that day)
Today is "Wear your favorite sports jersey to school" day. I, of course, own no such gear. But Irene reminded me of one of my favorite nerd shirts:

Cardinal numbers are a generalization of the natural numbers used to measure the size of sets. The cardinality of a finite set is a natural number: the number of elements in the set. The transfinite cardinal numbers describe the sizes of infinite sets.
Aleph null is the smallest infinite number. It is the cardinality of the set of natural numbers.
Neither has anything to so with sports so far as I know (but then again I wouldn't know, would I?)
So, today I am walking around in this T shirt which I am predicting very few people will ask me any questions about.

Brown Sugar, Clumsiness, and Feeling Down
Years ago, when I was living in Houston, my Dad called one morning before work to tell me his own father had passed away. It was expected but still, of course, a blow. I remember eventually getting myself ready for work and then my car not starting. "Great, of course my car breaks down on a morning like this..."
I called AAA and the guy tried starting it just for kicks. It cranked right up! He looks at me with a questioning face then shrugs and goes on his way... Much later I realized that, because I was feeling down, I didn't even depress the clutch all the way down to the floor when starting the engine and that's why the car wouldn't start for me.
A few month back, my father-in-law was kindly checking in with me while I was grilling some food in his backyard about Irene and how she's holding up with all that she's dealing with this year(*). I replied cheerily enough, but, a few minutes later, his serving platter slipped right out of my hand and shattered into a million pieces in front of me.
A couple of days ago, I stopped for a moment to collect myself on my usual walk home. (There's a path that leads through a narrow band of woods from the high school to my backyard.) Recently, Irene has been dealt yet another blow in a year of bad news for her(*) and I just needed a moment of silence in the woods to collect my thoughts. Somewhat grim-faced, I ducked under a small tree that had been partially blown over in a recent storm (one that I have ducked under many times in the past weeks) and, instead, smacked my head straight into it hard enough that I was stunned for a couple of seconds and didn't realize I was bleeding until I got home.
The next day (yesterday), a couple of students 'in the know' brought me cookies(**). Luckily for me, there were other students coming in and out of the room so instead of tearing up, I got to be my typical irreverent, goofy self when they insisted I eat them right away since they were still warm :
"Hey, let me do a degustation of these" (sniffs dramatically)
"Hints of cinnamon?" (nibbles dramatically)
"Ahh, some brown sugar?"
The students nod and laugh, recovering nicely from their confusion when they thought I had said "disgusting" instead of "degustation". (I always forget that some plain french words are super-fancy in english).
Much later, the students confess there was no brown sugar but they didn't want to ruin the moment. I confessed that I should have said I 'degustated' hints of love in those cookies alongside of the nonexistent brown sugar.
Brown sugar is just white sugar with some of the sugar molasses that is usually separated out stirred back in. Maybe clumsiness is my body stirring back into my life the emotions I try to separate out...

(*) If you are interested in Irene's battle with cancer, she maintain a very thorough blog here.
(**) Not the first time a student has brought me cookies when they found out. Teaching may bring low pay, a lack of respect, and a lot of self-doubt - but it is not without its perks!

Getting Inside Their Heads...
Most days I love my job and have no regrets. Some days, though, I'm filled with regret and self-doubt. It's human nature to question yourself, I suppose, but I have a secret trick for my down days:
I think back on my own high school years. I don't remember every single teacher certainly, but I do remember a fair number of them. Some I can picture clear as day, standing at the chalkboard, making some clarifying remarks or holding forth on some topic. Sometimes I just remember the tenor of how they talked and how they ran their classroom. The point is, they are in my head. In a way I carry them around with me all the time.
Then I think, others must also be walking around with some of their high school teachers in their heads too, right? Now that I've been teaching for 18 years, that's like 1600 students that have spend a fair chunk of their youth in my class (some fools even sign up for a second year of Rideout in AP Physics or Astronomy!) That means at least some of them have me in their heads for the rest of their lives, right?
After, having used this secret trick, I go back the next day into the classroom and do my thing. And, guess what, that regret and self-doubt gets to take a hike for a while...

First Day of the Season below Freezing...
Wednesday, November 6, 2019
You look like... (?)
So, I've been confused with Mr. Krasnoo, Mr. Delaney, Mr. Keaney, etc. Not too surprising - middle aged white dudes - we are all pretty interchangeable...
However, picture, if you will, confusing me with a 17 year old girl.
Once, long ago, when I had long hair, a waitress came up to my grandmother and I at a restaurant (she approached our table from behind my chair) and said "Hello ladies, what can I get you?" The victorious, mischievous smile my grandmother (who disapproved of the long hair phase) wore after that remark is one of several reasons I cut my hair a few months later. That incident is probably the closest I've come before today of being mistook in such a major way.
Today, AA was looking for me, glanced into the science office and saw me seated at my desk. She walked in and came up to my desk only to find her female classmate AT seated at my desk instead.
To help her out in the future, I created this handy Venn Diagram, I was quite surprised that the common intersection outweighs the differences. So, don't feel bad AA - I'm actually surprised more people haven't made the mistake:

Communicating and Storytelling
Le Ton-Ton et Moi, 1992 (?) |
I remember clearly this moment in Pittsburgh when I was in my mid 20's and I was at a dinner party with maybe 15 or so CMU grad students and I was telling a story. I looked up and every face was turned to me and listening intensely. I was slightly taken aback and realized that I was channeling my uncle. This picture above shows Uncle Roger and I circa 1992 one summer in Corsica. He is the most masterful storyteller I have ever met. I have seen him talk about a grocery store visit (that I was with him on!) and have an audience of sophisticated adults just eating out of the palm of his hand as he pontificated about us shopping for bread and eggs or something. Great storytellers don't even really need good material, they have an intensity about them and an intuition about their audience that allows them to just get right in their head.
Today I was talking to AT while she was prepping for her French oral test and it got me thinking about how much of good communication is using words that others want to hear, phrasing things like they do, even inflecting accents in a similar way. My uncle is not multilingual but his gift at communicating transcends language. Part of his trick is to actually speak with the accent of his listener. After spending a day with me, my aunt will laugh at him and call him out for speaking French with an American accent! I have seen him go from speaking continental French with a colleague to Arabic-accented French with a Moroccan field worker to Corsican-inflected French with the Corsican foreman. No one even seemed to notice except for me - it was amazing!
Now, I'm thinking about how just the other day when AC was talking in Mandarin to her friend (LL) and I inserted a couple of comments in English in the middle of their conversation. She was surprised and asked if I actually knew Mandarin or was a lucky guesser. In retrospect, I just knew they were talking about directions and between the body language and maybe a word or two here and there, it just made sense. So much of communication is assumption and circumstance, isn't it?

The Puzzle of Art
Newly arrived in a classroom near you:
Detail from The Persistence of Memory (1931), A surrealist painting by Salvador Dalí
"The soft watches are an unconscious symbol of the relativity of space and time, a Surrealist meditation on the collapse of our notions of a fixed cosmic order" - Dawn Adès
However, according to Dalí, the soft watches were not inspired by the theory of relativity, but by the surrealist perception of a Camembert melting in the sun.
Young Ken would have thought "Oh No, I'm not suppose to enjoy the relativistic (general, not special - for the record) implication of the art as it was not the artist's intention."
Older, slightly wiser Ken thinks the art and his experience of it is its own thing and anyways, as discussed in the book Art & Physics (Shlain, 1991), often new ways of looking at things in the art world is mirrored in the scientific world. As mankind is ready for a more sophisticated grasp of the universe, why wouldn't the art world and the science world be making big strides at once and maybe in similar directions?

A Death in Corsica
1986
Corsica, France
It was the summer before my junior year and this time I was spending a full six weeks in Corsica with my aunt and uncle at my grandfather’s house in Corsica. My buddy Erec had come along and that idyllic summer was filled with swimming, water skiing, hiking, eating, snorkeling, and afternoon siestas following late night dinner parties. One day we took a boat all the way out to the small isle of Monte Cristo (a real place!) and had a flying fish land in the boat! I remember sending hopeful postcards to a girl I had had my eye on in algebra class the previous school year. I felt like life was just beginning and it was beautiful and full of possibilities.
We all were living downstairs while my grandfather was slowly dying upstairs. He had been in declining health for years and this particular summer he was coming in and out of a coma into which the doctors told us he would one day just disappear. My aunt and uncle were taking care of him in the house as is the custom in the Mediterranean and I would sometimes read to him aloud a letter than my mother had written him from America. The juxtaposition of my vibrant youth and his dying days is a memory that lies at the heart of who I am - like a pillar around which my other emotional experiences are draped.
One night, Erec and I had been left to fend for ourselves and to keep an eye on my grandfather so my aunt and uncle could take a much needed break with friends on the other side of the island. They had a monitor set up so my grandfather could call for help if he happened to wake up and needed something. However, he never woke up that particular night and all we ever heard was the deep gasping breath with its laden pauses that only a person near death and in a coma can produce. How clearly I can remember those long pauses and the waiting. Eventually you would hear a catch followed by a painful, ethereal inhalation of breath that was frankly frightening. A storm moved in and one of the lightning bolts came down so close it popped all the fuses. I had to get a flashlight and Erec and I would go outside, up the external stairs, in the wind and the rain and the lightening, to get to the upstairs fusebox. The craziness of the storm shut out by the closing of the heavy door at the top of the stairs. In the silence, my grandfather’s painfully morbid breathing filled the darkness.
One day, about a week before he died, we were having an outdoor dinner party and he suddenly appeared like an apparition. Clean shaven and dressed, no one saw him make his way downstairs to join us all at the table. He hadn’t even gotten out of bed in the previous 10 days, but there he was looking us all soberly in the eye and making jokes about getting old and, in his own quiet way, saying his goodbyes. That was the last time any of us heard him speak. Much later, after the funeral, my uncle told me my grandfather had asked him “When does Kenny leave?” “Not for another 3 weeks,” my uncle replied. “Oh, I won’t be able to hold off that long…”
He died quietly one night and, in the morning, as Erec and I were getting ready to go out for a run, my uncle called softly through the window: “Ken, you must call your mother. Tell her Papy has died.” I paused for so long he called again “Did you hear me?”. I remember the shocked look Erec gave me when I said under my breath, without thinking, “This phone call is going to be a killer.” My uncle dialed the number and my Mother’s voice was initially so excited to hear from me. As I realized I was the one to deliver the bad news, the one to turn her excitement over getting a call from her son to the dread of facing the death of her father, I felt all the layers of my being imploding inward. She asked, “Is everything all right?” into the silence on my end. All I could get out was a faint “No…” There was moment where time stopped and nothing happened. Then my aunt kindly saved me by saying to my uncle “Take the phone – can’t you see he can’t do it?”
At the funeral, a distant relative stopped in front of Erec and asked “Are you the grandson?” and I cried “Non, c’est moi!” too loudly and everyone looked up, startled. I recall the strength with which my right hand gripped the wrist of the left hand. As if by squeezing hard enough I could contain the sorrow and stop the tears from flowing. To this day, if I am trying to control my emotions, my right hand clamps down on my left wrist like a manifestation of my conscious self asserting dominance over the emotional part of my brain. On that day, I did hold back the tears for a long time. I’m not sure why I tried so hard, but I think part of me was worried that, once I started, I would never be able to stop. I didn’t even cry when I saw my uncle discretely place the latest letter from mom, unopened, inside my grandfather's jacket as he lay in his open casket. Eventually the time came to close the casket and one of the workers used a power drill to screw in the cover of the coffin. The shrill mechanical screech that ended abruptly each time a screw hit its limit was just too much and I burst into tears and sobbed so hard I thought my face would melt away.
When I remember my grandfather, I usually go back to an earlier summer day when I was eight or so and a different storm had moved in while the family was at the beach. As the waves rose higher and higher, everyone else left except for the two of us. We played in the waves as they crashed into the shore with frightening intensity. He would throw me over the waves, into the waves, over and over again. At one point a rescue helicopter hovered overhead to see if we needed help. We laughed and laughed and I felt so alive…Even now, I can close my eyes and feel that moment. Perhaps that joy is at the center of that emotional pillar that all my other experiences are draped upon...

Facing Eastward, Measuring Angles, and Rotating
AC and I were talking about the Cardinal directions in Mandarin when I made this connection:
Apparently, Mandarin speakers start with East and work their way around clockwise (East-South-West-North), but westerners start with North.
Turns out "North" derives from an older word meaning "to the left". So, we too are facing East in a sense when we start with "North"! I'm thinking of how the standard angle in math is also measured from "eastward" on graph paper:
On a related note, I just found out that the Mandarin word for compass is "south-pointing needle" (zhǐnánzhēn (指南针)). Once again, Mandarin makes more sense! The magnetic reason why the "north" end of a compass points the way it does is because of a magnetic south pole lurking up there inside the arctic circle attracting it! The north end of the compass is indeed south-seeking!
Why we ever chose to call the North Pole direction of the planet "Up" is the subject of an older blog post.
However, at least our planet's rotation is consistent with the Right Hand Rule (yet another arbitrary decision we have settled on) for rotation: Grab the planet with your right hand with your fingers curled in the direction of rotation and your thumb picks out the direction of rotation, which is north ("up"). I thought this must be one of the reasons we adopted the right hand rule in the beginning but my internet research tells me this is simply a coincidence!
North is to the left of East, the original ordinal direction. The North pole is "Up" arbitrarily but consistent with the right hand rule. The right hand rule works for positive charges which is what Benjamin Franklin thought was the charge of the charges-in-motion (before electrons were discovered). (Interestingly, people are still arguing whether Franklin was a leftie or a righty...) Of course which subatomic charges we labelled "positive" and "negative" was, itself, arbitrary!
So, right handed people from the Northern Hemisphere have determine which way is Up and that electrical current is the motion of positive charges. Now we have to live with all of these arbitrary decisions!

I've written before about how much of a fan of Daniel Kahneman I am (Nobel prize winning psychologist).
I just recently listened to a really great interview with him and am going to post my notes here because I think they reveal one of my favorite things about thinking: We don't think the way we think we do!

Happiness is not the same as Life Satisfaction (satisfaction is when you are actually reflecting on your life). Happiness is mostly social (being with people you love and who love you back). Satisfaction is more about money, prestige, etc. Surprisingly what people want is satisfaction: they want to have a good story about their life. Having a lot of money does not make you happier (above a certain threshold), but life satisfaction does not satiate. Money is a proxy for success – that’s why so many rich people are working their heads off.
How to change behavior – it’s hard to change! When you want to change someone’s behavior, you really shouldn’t push them, instead ask “why aren’t they already doing this?” These restraining forces should be removed (rather than applying additional forces). (Don’t add to the driving forces which is what most people do naturally, instead work on weakening the restraining forces). Imagine two sets of opposing springs and how they hold something in equilibrium. Adding driving forces increases overall tension whereas removing restraining forces moves a person but does not add to the overall tension.
Behaviors are not from personality, it’s from the situations they are in. “Fundamental attribution error”: people tend to think that personality primarily driving their actions when it’s probably the situation they are in. It’s more painful to give something up than to not get something. Things are more expensive than anticipated for society/government because you have to compensate the losers.
What gets in the way of clear thinking is that we have intuitive views of things; “ready-made answers.” Independent clear thinking is basically impossible. Our ‘reasons’ are made up to support our existing beliefs. Smart people can be better at inventing ‘reasons’ so that doesn’t actually make them better at clear thinking.
Most organizations make decisions poorly: it’s hard to improve decision making. You should slow down. Use algorithms instead of using judgements.
When you are making decision, break the problem or job applicant into dimensions and evaluate each separately. Delay your decision, focus on the separate points. People decide too quickly and not too well. Don’t allow people to give their final judgement while discussing. Otherwise you spend your time reinforcing your initial impressions.
Protect the dissenters in your organization. They are valuable.
Judgement is a measurement where the instrument is your mind.
Not much hope of individuals overcoming their own biases. Organization can to better: they think more slowly and they can rely on procedures.
When you re negotiating, the person who moves first has an advantage: the first number thrown out changes everyone’s view of what is plausible. When negotiating, actively disagree with a number that is absurd (“erase that number”).
Do a pre-mortem on any decision. “Suppose two years from now, the decision has turned out to be a disaster. Write down the history.”
Why don’t people/organization delay decision making, evaluate point by point rather than holistically, and do pre-mortems? It’s hard work – much easier to go with your gut or someone else’s points…

The original mediocre, but over-rated white guy
The poster boy of cultural appropriation: "Hey, lookie here, I discovered these islands with all these Indians running around on them!"
The poster boy of white privilege: "Whaddya mean the world is much bigger than my bad calculations? I'll just call this unexpected continent part of Asia anyway and take all the credit!"
Cheer up my fellow mediocre white men, we have a holiday celebrating one of us!

Manning Up
I have a T-Shirt that has, in big bold letters:
It's the title of a modern dance piece by the Bill T Jones/Arnie Zane Dance Company that I saw in Pittsburgh back around 1994.
I was moved by the performance and bought the shirt because it looked cool and I wanted a memento of the show.
The piece is about life-threatening illness and other weighty matters.
Now, in trying times myself, I find my thoughts turning to what it means to be a Father and a Husband and a Son and a Brother; quintessentially male roles. I don't usually think about life in these terms but sometimes it is interesting to think on what it means in modern times to be 'manly' or 'masculine'.
As I sometimes feel helpless in the face of problems inflicted on others near and dear to me and wonder what am I suppose to do, how am I suppose to act; I am comforted by the thought that for those that rely on me:
Manning up may be as simple as still being here...

Relationships, Laws, and Reasons Why
I'm a big Vsauce fan (who isn't?) In his recent video, Laws & Causes, Michael Stevens engages in his trademark smart and entertaining intellectual meanderings. I really liked his bit about how just knowing about the relationships between variables doesn't actual explain the cause of the relationship itself. However, I feel he really missed a golden opportunity in this video in his explaining of the "cause" of angular momentum.
True, simply labelling a phenomenon as "angular momentum" and understanding the relationship between the variables involved in not the same as understanding the cause of the conservation law. But when he unpacks conservation of angular momentum in terms of forces and inertia (which he does a nice job of!), he actually took the explanatory arrow in the wrong direction!
It turns out conservation of angular momentum is not caused by torques, inertia, and forces as he implies. It's actually the other way around! All of Newton's Laws are simply manifestations of the existence of a couple of conservation laws (specifically Conservation of Linear and Angular Momenta).
So, Vsauce, you should have taken that big brain of yours over to Emmy Noether who actually explained to us where conservations laws come from! Turns out that although you can explain conservation of angular momentum in terms of forces, torques, and inertia, it really is the angular momentum that is the transcendent quantity that nature cares about. So why does conservation of angular momentum exist? Symmetry.
If you want a universe where the laws of nature are the same no matter which direction you face, then there must be a corresponding conservation law: angular momentum (thank you Noether's Theorem!).

Matt Damon ain't got nothing on me...
So, back in June, I was about to throw out some old, sprouting potatoes. I asked Seb if he was interested in doing an experiment and he said yes. We dug a short, shallow trench in the weed-infested corner of the backyard we call a garden, cut each potato in half and dropped them in. We covered the trench back in and left them alone until today.
This afternoon we dug out a couple handful of mini potatoes. I oven baked them and we all shared them as part of dinner!
And I'm not even the best botanist on Mars!

Trees, Dieting, and Investing
It's quite common to try to stump people with the old "Where do trees get most of their mass?"
But I only recently realized that when we lose weight, we lose weight the exact same "weigh":
CO2 > O2
That's it, you lose those 10 pounds one atom at a time on the exhale just like trees get taller and thicker one atom at a time taking in the very carbon you're breathing out.
I've known the basic chemistry facts my entire life and yet the first time someone asked me these questions:
"Where do trees get their mass?"
and
"Where does the weight you lose go?"
I thought and answered other (dumb) things: "From their roots", "In your poop"
Goes to show, knowing stuff doesn't mean you really understand stuff!
Chalk another one up to the power of small things done regularly leading to big changes.
Isn't that the basic advice of investing and saving money? (put a dollar a day into the stock market and you will have about 600K in 50 years!)
So, take a deep breath, plant some trees, and start saving some money!

Proust, Ratatouille, and Neuroscience
Highbrow: Proust's madeleine
Quotidian Reference: That eponymous scene in the movie "Ratatouille":
Neuroscience: Smell is the most primitive of the senses. Think upon a single celled organism's need to hone in on a chemical gradient to navigate to a food source or away from a toxic source. When a memory is associated with a smell, it bypasses all your higher brain functions and transports you back to the first time that smell was imprinted on you. If something smells good to you, it will make you happy almost no matter what!
If you are around family or really good friends, how much of that lowering-of-the-blood-pressure, that almost immediate sense of satisfaction, might be due to some pheromones or other unrecognized-by-your-conscious-brain olfactory stimuli?
Why do mammals nuzzle and kiss their young all over? We are all just imprinting our cookie and ratatouille smells with feelings of belonging and love!
A kiss is not just a kiss, is it?

Apology
Dear KP,
I feel I owe you an apology after you said I wasn't a "real" teacher a few weeks back. I knew you didn't say that in a mean-spirited way, but I still gave you grief about it. Last Friday, I thought of your explanation that you only meant I wasn't the usual-sort-of-teacher when in Astronomy I was having the students log into Itslearning to take a "test" of whether they could correctly click on my face in this picture of me and MC (it had to be done, seriously, it did!). While they were logging in, Clash of Clans came up and the Hive startled chortling in amusement as all the boys started logging into their own game on their phones to check out my set up and making comments like "Not bad - but your walls are way too weak for that level castle." or "Can I join your Clan?"
As I reflected on that moment, in the moment, I thought "So, this is probably the kind of thing KP was referring to...."
Apologies for doubting your characterization of me!
Sincerely,
Mr. Ken Rideout

Slowly Pulling My Way
Turns out I've been teaching for 17 years now. Wow! Since most days I'm hanging with (and acting like) 17 year-olds, it's like I've been doing this job all my life!
So, you'd think I'd be better at it, right?
I've been trying to design a good pulley lab for all 17 years. You know, the old block-n-tackle simple machine. It's an easy concept but usually a real eye opener ("Wait, each point of contact of the string exerts its own force on the load?").
For years, I had kids measure the various forces with spring scales, then I had them measure them with Vernier force probes. Then I had them measure the work done in lifting the same load in multiple ways. Invariably, the students would get caught up in the slight imperfections: something that should be a force multiple of 5 would come out as 4.8 or they would calculate the pulley system was 95 % efficient or something. Then I set up stations they could walk up to and read off the forces so they couldn't mess it up. It was never effective!
All I ever wanted was for them to experience the force multiplier as the number of points-of-contact of the string.
Finally, this year, I just strung up two block and tackle machines side-by-side. One had three windings and one only had a single string. I asked them to pull on both at the same time and compare how much force they had to exert while noting how each one went up a different amount.
One is three times easier to pull but only goes up 1/3 as much for the same pull. No calculations or measurements, just a qualitative question or two. Instead of frustration, I got "That was a good activity - I think I get it..."
Sometime a simple experience is the best explainer for a simple machine.
Imagine how good I'll be in another 17 years...

Back to School Night
So, every year we host the parents one night to run through their kid's schedule and meet their teachers. The following day, I was checking in with my juniors about what kind of report they got about me from their parents when one junior (JW) told me about the following conversation between her and her mom:
Mom: "Well, I'm so glad you're the youngest and last child!"
Student: "Why?"
Mom: "I don't think I could bear to hear Mr. Rideout's How-I-Quit-Carnegie-Mellon-to-go-make-wine-in-France story one more time!"
Apparently I had taught both of her older brothers a few years apart several years ago.
I told her that my stories are like fine wines - they get better with age!
(I think she may have actually rolled her eyes at me when I said that - yikes! It's going to be a long year...)

Celebrating Voting
It's very fashionable to celebrate the 100 year anniversary of women getting the right to vote. However, as Irene pointed out to me, the tale of voting rights is much more complicated than that ("100 year anniversary of wealthy, white, long time resident women getting the right to vote" just doesn't have the same ring!). It's an interwoven tale of federal citizenship rights plus federal voting law plus (and this is key!) state specific legislation.
Piggy-backing on some research that Irene forwarded me, I picked out the most interesting dates to me and created this scaled timeline (pet peeve alert: can't stand it when people do timelines with no scale - what's the point? That's just a chronological list!)
How come racism and sexism is so ingrained in modern society? Stare at the chart for a while and see if you can find an answer...

T. H. White and Socrates
Traditionally, when a student asks me "Why?" in a metaphysical sense, I respond with the old trusty and pithy Socrates quote:
"The unexamined life is not worth living..."
Socrates |
However, I just ran across someone quoting Merlin in T.H. White's classic The Once and Future King which spells it out a bit more:
"The best thing for being sad is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honor trampled in the sewers of baser minds.
There is only one thing for it then - to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust , never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you."
White |
I should have known it - Merlin was a physicist!

Her calculations were right on though - I had to round up to 3 cubic yards to get free delivery!

False Idols, Bacon, and Physics
For years I've been struggling with expressing why learning physics is hard (e.g. lying, words being imprecise, belief, our shallowness, objective vs subjective, bad intuition).
For months I've been picking my way through an impulse buy, one philosophy idea at a time:
Today I read the passage for 1626:
Francis Bacon and his four false idols that prevent us from seeing things clearly. Aha - here it all is, already nicely packaged:
Here I was all embarrassed by my impulse buy being somehow low brow, but - you know what - turns out I should have studied more philosophy in school!

Family Reunions, Now and Then, Half and Half
On Irene's side, there's an annual get-together in Old Saybrook, CT.
Here's the oldest picture of the two of us at that get-together:
Here's the most recent picture:
We look just the same, right? ;)
Despite the older generation bowing out more and more as the years go by, there are plenty of new young folks joining as you can see below:
I think this get-together may be the biggest convention of 'halfies' (what I call my kids: half asian/half white) on the East coast. Check out this pic of just the younger generation:
