“You Can Tune a Piano but you can’t Tuna Fish” (REO Speedwagon 1978)

Several years ago, I purchased a violin with the intent to learn how to play.  I liked the portability of the instrument.  My reasoning at the time was that there was no excuse not to practice; I could take it anywhere.   I am a fan of the Irish pop group The Corrs (Forgiven not Forgotten) and also love listening to classical violin performed by Hilary Hahn (Barber & Meyer Violin Concertos).  When the violin is in the hands of a master, there is an incredible range of tones that sympathetically vibrate to each other, producing resonances that always evoke an internal response from me.  My inner core loves music – I can burst in to song in reaction to what someone says or when experiencing an event; the song just pops out of my mouth and is not always appreciated by the unlucky person next to me.  (I have been told that maybe my voice would sound better in a choir.)  As for the violin, I love the feelings of happiness and sadness that can be produced from what I considering a very sexy looking instrument.
As for my violin playing, I found a teacher and was prepared to learn.  After one particularly discouraging lesson, I walked into the main studio area located off the hall where the small lesson rooms were.  There was a man and a young girl (perhaps 6 years old) seated on the couch waiting for her lesson to begin.  She was holding her violin case in her lap, her hands clasped the handle and she had that eager look of youth – all hope and bright prospect.  Knowing that they probably heard my excruciating performance and expected a four year old to walk out of the lesson room, I could not resist saying, “If you practice hard, you too will be able to play like me.”  The little girl’s eyes opened wide (perhaps in fear) but her father laughed.  His booming guffaw eased my disappointment at how lousy I was.  At least I could make someone laugh at the humor of the situation - a 50 year old woman trying to play “Lightly Row” and not doing very well at the task.   
What does this remembrance have to do with physics (the topic that I am using as my writing prompt)? 
This past week, I took exam number two in the introductory physics course I am taking; part of the content covered was a brief overview on simple harmonic motion relating to the swing of a pendulum and the oscillation of a spring.  (I put a lot of work into plotting mass against time and mathematical predictions of potential energy and kinetic (motion) energy).   In the lab and with my home experimenting, I could not help but understand that the curve on a graph of the vibration, created by the oscillations, repeats itself regularly and, if there are no frictional forces, the movement would go on indefinitely.   I find these formulae and patterns to be amazing and, hopeful, because in physics there is also restoration.   Gravity is the restoring force for the pendulum – pull it to one side and gravity pulls it back to the center.  Or in the case of a mass attached to a spring (for example, a block of wood),  it is the elastic motion of the spring that moves the wood and once the movement is slowed to a stop, I can pull back on the spring to restore the potential energy. 
This week I read that on a piano (specifically in western music) songs created are based on twelve tones – only twelve arranged in different patterns give rise to the repertoire of songs I like to belt out.  I can play the note ‘B’ (494 oscillations) and a ‘B flat’ (466) and nothing in-between.  I can’t produce a note that is say 475 oscillations; it is not possible on a piano.  (Roger S. Jones)   In contrast, I can play an infinite number of tones produced from the strings of a violin; although, in my case, the listener may want to cover their ears while I am undertaking the job.  
For me, I see a similarity in life, I need restoration and I like knowing that in the natural world, as I learned in physics this week, there is continuity, a pattern, and restoring forces … in one sense, an ability to be tuned.  Writing this blog is my attempt to rewind myself, to tweak my writing with the hope that I can offer something helpful to those I interact with.  I know that even if a piano is tuned perfectly the twelve tones can be combined to produce sounds painful to hear – that is not my goal.  As for the fish (in my title), to my way of thinking, I agree.  A fish does not have to be tuned; if life didn’t interrupt, it would keep on swimming.   But, then … there is always the possibility of that darn old worm dangling at the end of a lure camouflaging the nasty hook.

“Butterflies Are Free to Fly” (Elton John)




This guy is not free to fly.
The chaos theory is a field of study in mathematics that has applications to physics (and several other disciplines).  I used the metaphor of the the butterfly effect, which is based on the chaos theory, in the prelude of Heart Root. A brief and inadequate synopsis of the theory is that small differences in initial conditions yield widely diverging outcomes for some dynamical systems (based on Newtonian mechanics).  An example would be a mathematical model describing the number of fish each spring in a lake.  Small changes in the conditions can cause deviations in the otherwise natural number of fish.  

What brought this to mind today is a butterfly seemingly peering out my kitchen window.  Keep in mind that I live in Michigan and the outside thermometer reads 28 degrees (F). The tiny insect perched on the window sash is perhaps instinctively longing for the warmth of light.  So am I - but there is no sunshine today.  As you can see in my terrible photograph, the deck railing is snow covered and the sky grey and bleak. 
I am not sure what natural system I disrupted by transporting this delicate Lepidoptera.  A possibility could be my recent purchase of  flowers, hoping the warmth of the orange color could help brighten my mood.  I also purchased a fragrant bouquet of fresh basil.  Perhaps the butterfly was nestled in the aromatic fumes of the fresh herbs, of course, with no knowledge that he was headed for demise. 

Measuring from the tip of the wing to the head (minus antennae), it is 2.5 centimeters.  The color is a green with yellow undertones and the entire wing and underbody are streaked with a thin mist (like overspray) of dark, ink color reminding of a minute piece of art detailed in pointillism. I encouraged the tiny visitor (or captive – not the same as guest) to open his wings.  Although fluttering wildly, I can see that the wings are white/yellow with distinct black circular markings, each wing identical and edged in black.  Using binoculars designed for insect study, I view that his body is covered in delicate, pale-yellow fuzz.   His head is more punk rock – a spiking of black and yellow covering from which two slender antenna extend.  His macro appearance reminds me of an Elton John costume from his flamboyant early concerts.  This butterfly is not free to fly –  fly away bye bye.  He is going to die.  But then, we are all dying – from our conception in the womb, there is that predetermined finality.

Recently, I have been reading work by Amit Goswami PhD (Quantum Physicist).  He states that our consciousness does matter in how we experience life.  Well, I am not sure if life is a projected hologram from my mind or not.  I can imagine that there is the possibility.  What I do know is this:  I believe in the chaos theory.  And, the butterfly in my kitchen will most certainly die soon...not because of me (I have no plans to speed up his last hours) but, because that is how life goes.  What has been disrupted by its capture...I’m not sure.



Excerpt from Prelude (Heart Root):  My mind’s eye works like a camera...through the lens I consider a tree falling in slow motion, the focus automatically sharpening on a nearby squirrel as it scurries away.  In the distance, a doe lifts her head twitching her ears forward as a fawn peers out from beneath her.  Audio wave lengths interact with my ear drum – a screeching crow takes flight at the tremor of cracking wood; the large bird powerfully moves its wings disturbing the air into a wind...whoosh...whoosh.  Canadian geese take off from an unfrozen pond creating ripples, tiny waves that slap the edge of the shoreline.  This energy gust creates a steam of air that picks up speed as it travels close to the ground, through a neighborhood, swirling under a poplar tree and continuing over frost covered blades of grass to the back door of a brick house causing the loose metal weather stripping to hum.

The Dog Ate My Homework

No dog ... so I can't use that excuse.  The lights went out?  No, that was the Super Bowl.  

In truth, life ... life "stuff” filled in all the empty space this past week.   Here is a fact I can share though:  Upon the completion of next week's blog entry, I will have taken my first physics exam.  Do I understand what I have learned; can I do the math?  I am looking forward to this assessment - I don't know what I don't know until I am put to the test.
