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:
(Puzzle assembled by Irene and Isabelle Rideout)

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.
Direction_in_Chinese.jpg

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:
Image result for standard angle

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!
Image result for magnetic south pole of earth
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!

Making Decisions, Being Happy, and Influencing Others

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. 

Image result for restraining and motivating forces
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!

"Claiming your stuff for my people too,
Ever since fourteen-ninety-two."

Manning Up

I have a T-Shirt that has, in big bold letters:

"Still / Here"

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.
Related image
Bill T. Jones in Still / Here
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).

Emmy Noether, 1882-1935

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!).
