It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery.  But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light, that transparent air reflects light, that in so doing it discriminates among the waves, and that the sky is blue for the same reason that the sunset is red?  It does no harm to the romance of the sunset to know a little bit about it.

If I Had A Hammer

Favorite Line(s):
Well, I’ve got a hammer
And I’ve got a bell
And I’ve got a song to sing
All over this land
It’s the hammer of justice
It’s the bell of freedom
It’s a song about love between
My brothers and my sisters
All over this land

Here we face a critical branch point in history, what we do with our world, right now, will propagate down through the centuries and powerfully affect the destiny of our descendants.
We are star stuff, which has taken its destiny into its own hands.  The loom of time and space works the most astonishing transformations of matter.  Our own planet is only a tiny part of the vast cosmic tapestry, a starry fabric of worlds yet untold.  Those worlds in space are as countless as all the grains of sand on all the beaches of the earth.  Each of those worlds is as real as ours.  In every one of them there’s a succession of incidents, events, occurrences, which influence its future.  Countless worlds, numberless moments, an immensity of space and time, and our small planet at this moment — here we face a critical branch point in history.  What we do with our world, right now will propagate down through the centuries and powerfully affect the destiny of our descendants.  It is well within our power to destroy our civilization and perhaps our species as well.  If we capitulate a superstition or greed or stupidity, we can plunge our world into a darkness deeper than the time between the collapse of classical civilization and the Italian Renaissance.  But we are also capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet, to enhance enormously our understanding of the universe and to carry us to the stars.

If you just lose your income that is one thing, because you can adapt.  You find another job or another field.  But once you lose everything — your home, your school, your clinic, your road, your church — then it’s an impossible situation.  You become an environmental migrant because you have to find those facilities in some other place.
   —     Elizabeth Meyerhoff
Up until now, the focus has been on stopping people from migrating in the first place.  Now the focus needs to be on how to make them an asset rather than a burden for the places they are going.
   —     Alex Randall
Of the U.K.-based Climate and Migration Coalition

I would rather have my ignorance than another man’s knowledge because I have so much more of it.
    —     Mark Twain
[I watched an “anti-vaxxer” getting interviewed and his excuse for not getting a shot was:  “We all gotta die of somethin’.
This is a poor attempt (by me) at sarcastic humor.  And, no, there is no indication AT ALL that Samuel Clemens was anti-vaccination.  In any case, at the time of his (Clemens / Twain) death only five vaccines had been discovered:  Smallpox (1798), Rabies (1885), Typhoid (1896), Cholera (1896), and Plague (1897).    —    KMAB]

We destroy our children’s songs of existence by giving them inhibitions, teaching them to be cynical, manipulative, and all the rest of it…  You become hardened, but you can find that playfulness again.  We’ve got to find a way to get music and kids together, as well as to teach teachers how to discover their own love of learning.  Then the infectious process begins.

Over the weekend, I had another music / guitar lesson from my brother-in-law.  He has a degree in music, plays saxophone professionally, and has been teaching music in public schools for over twenty years.  Part of the lesson was to think about “learning performance skills“.  Here is a modified version of his lesson (with supplemental info from Wikipedia)…
The four stages of learning skills are:
Unconscious incompetence  (You don’t know that you don’t know and you don’t know what you don’t know.)
The individual does not understand or know how to do something and does not necessarily recognize the deficit.  They may deny the usefulness of the skill.  The individual must recognize their own incompetence, and the value of the new skill, before moving on to the next stage.  The length of time an individual spends in this stage depends on the strength of the stimulus to learn.
Conscious incompetence  (You know that you don’t know something and recognize you don’t know it.)
Though the individual does not understand or know how to do something, they recognize the deficit, as well as the value of a new skill in addressing the deficit.  The making of mistakes can be integral to the learning process at this stage.
Conscious competence  (You know what you know, but you have to concentrate on it to do it well.)
The individual understands or knows how to do something.  However, demonstrating the skill or knowledge requires concentration.  It may be broken down into steps, and there is heavy conscious involvement in executing the new skill.
Unconscious competence  (You don’t have to think about what you know how to do in order to do it.)
The individual has had so much practice with a skill that it has become “second nature” and can be performed easily.  As a result, the skill can be performed while executing another task.  The individual may be able to teach it to others, depending upon how and when it was learned.

History is subject to geology.  Every day the sea encroaches somewhere upon the land, or the land upon the sea;  cities disappear under the water, and sunken cathedrals ring their melancholy bells.  Mountains rise and fall in the rhythm of emergence and erosion;  rivers swell and flood, or dry up, or change their course; valleys become deserts, and isthmuses become straits.  To the geologic eye all the surface of the earth is a fluid form, and man moves upon it as insecurely as Peter walking on the waves to Christ.

This post marks the first day of my 13th year of blogging here on WordPress.  The number of countries who’ve visited this site continues to grow and the number which haven’t continues to decrease.  North Korea and Cuba are still among them (the latter…)  I’m also still missing a belt across the middle of Africa and a few spots in Asia.  (Slowly, slowly…  Resistance is futile.)
On reviewing my content over the past year, I have done mostly two posts a day.  One is a thought, review or quote; one has been a music video.  My intent was to offer up to any who stumbled onto my blog a chance to sample some of the music which affected my life.  In the process, I’ve rediscovered a tremendous number of songs which came and went (in my life) and a core of songs and performers who have helped make me – me.  Not, physically, like food or drink or air, but spiritually…  Now that the year is completed, I doubt I’ll be continuing with the videos every day, but I will include them periodically (sporadically?).
My blog has continued to be an increasing part of my “normal” retired life.  I routinely receive about 20 to 60 emails (per day) from the roughly 300 blogs I follow.  I say “roughly” because I don’t check how many I follow.  I just looked, and I have fewer than 2,000 followers myself.  Every year there is a trade-off:  you pick up a few steady followers and a few drop off.  Those who actually post about leaving (their own sites) say they are simply moving on to other things.  Most, don’t bother and just stop posting.  A few come back after some period of time.  Many do not.  It doesn’t necessarily mean they’ve stopped blogging.  Some just move to a hosted service to try to monetize their thoughts and don’t provide me a way to follow them.  Or maybe they did and I simply missed the link…
At any rate, I am still posting thoughts, quotes, movie reviews, book reviews, and favorite music videos.  I easily spend an hour per day reviewing the posts I get (via email subscription) and sometimes that is simply overwhelming.  It’s not always the average blogger’s fault.  If you post something interesting, I (still) will go off and investigate it further: authors, artists, locations, books, movies, science / math / history topics – they will all lead me off down the rabbit hole.  And that hole can be DEEP!  I don’t know why, but this year, less frequently, I’m choosing to delete fewer (unopened mail / posts).  I apologize to you if you are one of those authors.  I will admit to only viewing actual posts sent to me (most of the time).  I seem to get a lot of “read more” posts / emails.  I’m not sure why this is.  I guess it’s a WordPress feature I don’t use or don’t know about.  There are a few (a handful) of sites which I know are visual and I more frequently click through to the actual site, because I’m interested in the bits which are not offered in the smaller / limited / text based emails I tend to receive.  I apologize if that affects your view stats negatively…
So, besides this blog, what am I up to?  My health has been mixed.  Last year, I was back in the hospital for “jump start”.  I have AFib and every now and then I get my heart zapped (“reverted”) to a normal rhythm.  We’ve also had this whole COVID lock down, which has put a damper on things.
In January, I purchased my first guitar and I’ve been practicing most every day since.  I “know” some basic chords and scales.  I’m still having a dickens of a time with strumming and chord changes, but I’m told that will come with time.  I now own two acoustic guitars and one electric (a Stratocaster style), and I have another acoustic on loan from my brother.  I have the four on a rotation calendar, but the first is still my favorite.  I’m looking into picking up a few more inexpensive guitars and two basses.  There is no time pressure.  It’s all about my ability to save (here and there) until I can justify a purchase.  [Wife:  How many guitars do you NEED?  Me:  …One more.]
The few things I’ve learned have truly been amazing (to me).  I do seem to have a smidgen of musical ability (although it’s still buried under layers of doubt).  I’m finding the ability to concentrate on practice to be as relaxing as zoning out in computer programming used to be (in my youth).  Sixty to ninety minutes can easily seem like five or ten minutes.  There is also the complete exhaustion which results from prolonged concentration – however “relaxing” it may feel at the time.  In a strange way, it feels good to be mentally tired at the end of a practice session.
But, am I getting any better at playing?  An objective opinion would be:  Yes!  Am I any “good”?  An objective opinion would be:  No!  Does it matter a whit?  No.  Why not?  Because, like blogging, I’m doing it for the enjoyment of doing it and not for the expectation (mine or anyone else’s) of being any good at playing guitar.  Again, like blogging, as long as it’s fun and interesting and fulfilling, I’ll just keep doing it…  My not so secret goal remains to write a song (lyrics and music) for my wife.  (LoL)
My personal goals for last year (to learn some assembly language programming and to have a play with chat-bots) never really got off the ground.   I spent a few weeks looking into them and playing with some free software, but the former has been passed by history so resources are limited and the latter is beyond my means as a retired person on a limited income.  In any case, I have usually been at my best when given a customer with a problem, not when I have to make up my own problems (and then create their solutions).
So, it’s guitar and blogging to keep me occupied (and mostly out of trouble).  LoL!!
Once again…  “Excelsior!!
