Popular Culture 20120810: Jethro Tull, the Beginning

One of the most complicated bands in many ways is the British band Jethro Tull.  They are complicated in their music, extremely complicated in their personnel, and almost mind bogglingly complicated in insofar as why I adore a limited set of their work and either care not a fig or actually dislike the rest.  I have such a love/hate relationship for any other band.

I do not understand why I feel this way, but I do.  At their best, they are superb.  When they are a bit off they are still better than most bands, but the material that I dislike is just awful, at least in my view.

This is why it has taken me so long to get started with this series.  I generally try to write about things that I have unambiguous feelings, usually bands that I really like.  Sometimes I write about horrible acts, like Ray Stevens, who really never did anything of real merit.  But to write about a band that can move me greatly with some material and with other material make me say, “What IS that?” is quite different.  Please bear with me!

My Little Town 20120808: The Forbes Dynasty

Those of you that read this regular series know that I am from Hackett, Arkansas, just a mile or so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a rural sort of place that did not particularly appreciate education, and just zoom onto my previous posts to understand a bit about it.

From the 1880s to the Great Depression Hackett was a booming town.  Coal drove the economy, but there was significant agriculture as well.  Coal was king, though.  Hackett coal is ideal for making coke, basically the coal counterpart of charcoal.  Coke was and still is used in enormous quantities to produce steel, and during The Gilded Age the steel mills were running at capacity.

Not just any coal will make suitable coke.  The particular kind of bituminous coal found at Hackett is ideal for coking and hundreds of men mined it there.  There were rail lines to carry it away and it found its way up north to the steel mills.

Pique the Geek 20120805: Yet More Carbon

Last time we finished our discussion of diamond, and now we move to what is pretty incorrectly called amorphous carbon.  Truly amorphous materials. like glass, have no true crystal structure (although there may be some local microstructures) that repeats regularly.

When used in the sense of carbon, only recently produced thin films of carbon are truly amorphous.  These are of research interest for the most part, although I would be quite surprised if practical uses are not found for them before long.

We shall discuss forms of carbon traditionally called amorphous even though they are not truly amorphous.  These include some of the most commonly encountered forms of carbon, and almost everyone has seen and touched at least a few examples.

Popular Culture 20120803: Leroy Jethro Gibbs

NCIS is really a good TeeVee program.  The writing is realistic, the characters well developed, and the mysteries usually pretty good, often with last minute twists.  Of all of the characters, Gibbs (played with aplomb by Mark Harmon) is by far the most complex.

This piece is not intended to be a history of the show, but rather my take on the personality of the character.  Various scenes that I remember may be used to illustrate my points, but once again this is more of a character analysis of Gibbs than a narrative of the program.

First and foremost, Gibbs is damaged goods.  He was always in trouble when he was a kid, often rescued by his father, Jackson (played by the wonderful Ralph Waite).  Some of these incidents are told in flashback, and the young Gibbs is played by Sean Harmon, Mark Harmon’s son by Pam Dawber.

My Little Town 20120801: The Gang

Those of you that read this regular series know that I am from Hackett, Arkansas, just a mile or so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a rural sort of place that did not particularly appreciate education, and just zoom onto my previous posts to understand a bit about it.

My maternal grandmum married John Mackey, a really nice man who had been a doughboy during World War I.  She had been widowed for many years (my grandfather died years before I was born) and John had been married briefly decades before, so he was essentially a bachelor.

John had a little candy store on Main Street in Hackett where he sold candy, cold soft drinks, flashlight batteries, and sundries.  He never made any money with the store because he gave so much stuff away to kids (like me).  He lived in the back of the store until he married my grandmum.  He had a little pension for serving in World War I and also a black lung pension for being a coal miner for years.

The store was the gathering place for the old men in town.  He had an awning over the storefront and several benches and chairs under it.  He also had chairs and tables inside for winter and he had a pot bellied coal stove in the store.  At the time coal was readily available for the consumer market in Hackett.

Pique the Geek 20120729: Carbon Copy

Last time we started talking about the allotropes of carbon, finished graphite and began with diamond.  Tonight we shall continue the diamond saga and maybe move to a third common allotrope.

Last week I was having some connectivity problems and, quite frankly, was ill with a bad cold, so I just did not feel much like writing.  I am better (much) this week and my computer seems to be functioning within design parameters.

Since the part that I wrote about diamond was so short last time, I shall paraphrase it as the start of this piece.  That way you do not have to hit the link to get up to speed.

Popular Culture 20120727: John Alec Entwistle

I apologize for being absent last week.  I had a nasty cold and started on this very piece but just did not have the energy to finish it.

I am still doing background on the series about Jethro Tull, but and not ready to start writing the piece yet.  They were much more complicated insofar as the band lineup goes than most of the bands about which I have written, so it is taking some time.

Tonight we are going to look at who I consider to be the greatest rock and roll bass player who ever drew breath, Thunderfingers, aka The Ox.  But he was much more than a great bass player.  He was outstanding on brass instruments, and much of the early work by The Who has a lot of French horn in it.

He was also an accomplished songwriter and singer, and many of his songs were performed by The Who.  Songwriting is much more lucrative than merely performing, so he was always to get more of his songs on records.

My Little Town 20120725: Gardening

Those of you that read this regular series know that I am from Hackett, Arkansas, just a mile or so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a rural sort of place that did not particularly appreciate education, and just zoom onto my previous posts to understand a bit about it.

I have written about Ma’s garden before and shall not repeat that.  If you want to read them, you can look here, here, and here.  What I want to talk about tonight is that I have begun harvesting from my own garden recently, and just Monday got the first large tomatoes and purple hull peas.  I had been collecting cucumbers for a while.

I garden in a rather unconventional style.  For starters, I HATE to hoe and will go to great lengths to avoid it.  I do not mind tilling, but my soil was still nice and loose this year and did not even have to do that.  At least with tilling, you do it once and are finished for the year.

I had a bit of trouble getting the garden started this year because it was wet in the spring (not as bad as last year).  I finally did get it in, though, and my philosophy has changed considerably since I first started gardening living alone.

Pique the Geek 20120722: More on Carbon

Last time we started our series on carbon, and I now expect it to run for four installments.  Amongst many other properties, carbon is unique in having more allotropic forms than any other element.  Also known as allotropes, these are pure elements with radically different properties.  The term is reserved only for elements, the term for compounds being polymorphs.  An allotrope is a subset of a polymorph.

There is also another distinction:  for an element to have an allotrope, it must exist in the same phase.  Thus, solid lead and molten lead (and lead vapor) are not allotropes, but rather different phases of a given element.

Before we concentrate on carbon, let us consider oxygen.  In the gaseous phase, it has two allotropes, O2, normal molecular oxygen, and O3, also called ozone.  For an element as reactive as oxygen, normal molecular oxygen is remarkably nonreactive (wait a few weeks), but ozone is extremely reactive.  But both are just composed of oxygen atoms.

My Little Town 20120718: Mathematics Made Hard and Easy

Those of you that read this regular series know that I am from Hackett, Arkansas, just a mile or so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a rural sort of place that did not particularly appreciate education, and just zoom onto my previous posts to understand a bit about it.

When I was in school I had the good fortune to have a great many excellent teachers.  I even keep up with some of my high school teachers, and I was graduated in 1973.  Sr. Cabrini correspond on Facebook, and Sr. Pierre calls me from time to time.  They were both excellent and I glad to call them my friends.

On the other hand, I have had some really horrible ones.  One who has to be near the top of the list was Bill Holder, a mathematics teacher that I had at Westark Community College in Fort Smith.  That is now part of the University of Arkansas system, The University of Arkansas at Fort Smith.

Pique the Geek 20120715: Carbon, the Stuff of Life Part I

There are only a handful of elements that are absolutely essential to all known lifeforms, and carbon is easily the most important.  Certainly hydrogen and oxygen in the form of water and other compounds are also essential, but without carbon there simply would not be life as we know it.  There are many reasons for that, but that discussion is not for tonight.

This time we shall start at the basics and next time we shall work our way into more complex topics.  Since carbon is so essential and important, this will be a multipart series.  I expect three or so, but that depends on how motivated I am to root around for things that will be interested.

Unlike beryllium and boron, carbon, at least 12C, is more common than it should be.  The reason is fascinating, and we shall talk about that tonight.

Popular Culture 20120713: Random Thoughts

I am not quite ready to start another long series about music just yet, but probably will begin next week.  Due to popular request, Jethro Tull will be the focus when we do get started on that.  I promised something lighter than last week, so here are a few random thoughts about my likes and dislikes in popular culture, past and present.

First of all, today is Friday the 13th.  I am not superstitious, but many folks are.  Not as many as in the past, but still many are.  Interestingly, friggatriskaidekaphobia is of quite recent origin, not being much noticed until late in the 19th century.  Reasons to be afraid of this combination of date and day are quite nonscientific.

Friday has been considered an unlucky day for a long time.  The reasons for this are unclear, but Chaucer mentioned it in the 14th century.  Twelve has always been considered a “good” number (we still use dozens, have twelve hours for each half of the day, and many other examples) and 13 is thus imperfect, and a prime number as well.  One popular idea is that because of Judas, 13 (including Christ) at a table is bad luck.  A similar idea also appears in Norse mythology.  Actually, the numbers 2 and 8 have a more scientific basis for being “good”, since they describe the number of electrons required to acquire the noble gas configuration in the elements.  In any event, I consider any Friday the 13th just another day.
