This feels like Fall





Afterthought

I uploaded this fresh looking Goldenrod to my previous post, but somehow in my haste I deleted it.  In a creek drainage just above the aforementioned blooming wildflowers there's quite a lot of Goldenrod blooming.  This is normally a late summer flower, so it's not unusual to see it persisting this late into the fall.

Springtime Flashbacks

 The Checker Bloom, above, usually appears by May and is gone by the end of June.  But, on the FRC campus, there's a small area near the Registrar's Office that is protected from the wind and probably picks up some heat from the building.  It's an area that gets hit by the weed eaters often.  But the warmth, coupled with the recent rains, has prompted some seeds to begin anew and here we have one plant showing three stages of blooming.  As you can see, it blooms from the top down, the newest bloom being on the right and the oldest, shriveling, on the left.
Nearby are several large patches of a Daisy Fleabane or Aster which is normally a mid- to late summer bloom, but here we are near the end of October and they look fresh as daisies.  Well, they are  daisies!

Theoretically.....Hmmmm......

 The most recent reading I assigned to one of my English classes was a piece by the great Harvard biologist, E. O. Wilson, titled "Intelligent Evolution."  This essay first appeared in Harvard Magazine in 2005.  For my students, it appears in the 2012 edition of The Norton Reader. I introduced the essay by telling my students that we're going to have to study some key words that are used in many different ways for many different purposes.  Some of these words are especially used differently by people who accept the theory of "evolution by means of natural selection" and those who do not.  I decided to do a little research on one of these words: theory.  I began by gathering most of the dictionaries and basic biology books in my house.  That included a couple of thesauruses and a "book of synonyms" which are kinds of dictionaries.  In class tomorrow, among other points, we'll discuss the difference between prescriptive and descriptive dictionaries.  The above photo is what my work space looked like when I began the research. 
 The first book I checked was a junior high life science textbook written for Christian Schools.  Not all Christian schools, but a particular type.  That is immediately apparent from the introduction.  This book devotes an entire 21-page chapter to Biological Evolution.  The entire chapter can be summarized by this one sentence: "The theory of biological evolution is not true, because it contradicts the Bible."  [The editor failed to remove the superfluous comma.]  I found the last two paragraphs of the chapter particularly offensive.  Here they are:
"Worldly scientists present evolution as fact. Many people simply believe what these scientists say and have never really considered why they believe in evolution.  Worldly scientists also present evolution as something everyone believes.  For a person not to believe evolution, he must be willing to say that that the majority is wrong.  Some people believe evolution only because they do not want to be different or looked down on.
"Satan wants people to believe in evolution.  This is probably the main reason that evolution is so popular.  Satan is a deceiver (John 8:44), and he wants people to believe that God's word is not true.  He keeps the belief in evolution popular because he can use it to lead people away from God."


So, what is a "worldly" scientist?  I guess I'll need to research "worldly."  Amazing stuff. 
 The Synonym Finder, my 1978 edition of a thesaurus-like book published  by Rodale Press, includes some widely-used synonyms for "theory" that explain a lot of the problem that is explored in E. O. Wilson's essay.  The excerpt shown several photos below begins with "hypothesis" but it gets worse.
 Next, I looked into a widely-used basic biology text found in colleges and AP high school biology courses.  It treats the word theory the way one would expect in a legitimate science textbook.  More on that later.  Can you identify the "forbidden fruit" in this photo?  No, not the apple or the banana.  It's the biology book, a book of knowledge!
 My old "Webster's unabridged" is impressive for its size, if not its contents.  I'm not sure if I keep it as an heirloom or a doorstop.  It's fun to consult it from time to time.  It does contain one of my favorite new words: deipnosophist.  I like to think I'm one of those.
 So, photos of my findings continue.  As you can see, the definitions of "theory" are all over the map.  Thus, the difficulty of discussing an essay like Wilson's among a group of people who might hold to different definitions. 


 This next one (below) is one of the worst from a scientific standpoint.  Most of these synonyms have no relation to evidence, reason, or scientific principles and are close in spirit to the word "guess."  One might even add "wild" guess.  Sad.

 The one below, helped by my famous left thumb, says a lot in very few words. It would even fit on Twitter! To do the word justice, though, one would need an expansion of this definition and examples from practice.  These, of course, are provided in the textbook.
 One last definition from one of the dictionaries makes a total of 13 images for this post.  On the chance that some of my students might have superstitions in relation to the number 13 (not that they will be counting), I decided I'd better add one more:
 So, I gathered up my research materials for one last photo.
So, the first assignment I'll be giving in relation to E. O. Wilson's essay will be a word search.  We'll  research several key words (evidence, purpose, mind, fact, inference, etc.) in the essay, then try to gain a better understanding of what's at stake for our society in the seemingly never-ending battles over evolution.

It's All About Leaves







The Last Stand





Some Squirrel Play

 I took a break from school work this morning to see if the Oak Treehoppers were still on duty at FRC.  As I headed up the paved walkway, I came to a group of squirrels playing chase.  They didn't let me get very close on my way up the hill.  I'm sure they were catching me closely as I inspected a large California Black Oak and looked for the Treehoppers (next post).  By the time I headed back down the hill, they seemed more comfortable with my presence, and I got some closer photos.  Click on them to get even closer.
