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.

My Little Town 20120711: Uncle David’s Boat
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 around eight or so Uncle David built a jon boat out of marine plywood. Uncle David is really good at woodworking and makes some nice pieces. As far as I know it was his first attempt at a boat. I rarely write about living people, but the humor in this piece is not at Uncle David’s expense and I bet that he gets a kick out of reading this.
He did a really good job of it, and it looked really nice. It took him several days to finish it, and since they lived just across the street I watched quite a bit of how he built it. He had gotten some plans from somewhere, but could have built it without any prepackaged plans because he was that good.

Pique the Geek (Elements) 20120708: Boron – Widely Used and Uncommon
If you follow this series closely, you will remember that the last element that we covered was lithium, and so the next one should be beryllium. However, I wrote about beryllium recently and so you can just follow the link.
Last week I wrote about fireworks safety, and my piece was prescient and unfortunately evidently not read by some unfortunate youths in Arkansas. My friend, who often comments here using the handle justasabeverage, sent me the newspaper article by email the other day that covers the topic after the fold.

Popular Culture 20120706: The Hateful American Family Association (With Poll!)
I am not ready to start a new, long series about music just yet, so tonight we shall discuss the hate filled, venom spitting American Family Association (AFA). This is one of the most conservative, evangelical groups that exists and qualifies as being termed a hate group by the Southern Poverty Law Center.
I go back a very long time with the AFA. When I lived in Arkansas, their radio stations were everywhere (as they are now) and they had also started a website, afa.net. They also run a radical news organization, onenewsnow.com (ONN). It is interesting that this could be pronounced either “one news now”, or “one new snow”. I like the latter better because their “articles” are a big snow job for the most part. It is ironic that ONN is also the acronym for Onion News Network, and their stories are often more realistic that the AFA ones are. I commented on some of their news articles and drew the wrath of the son of the founder. I wish I still had the emails that he sent me; they were mean spirited and nasty.
Before we get very far into this, let me make my philosophy clear. I am not a believer in any religion, but I am not one of those “evangelical atheists” who want to make it difficult for believers. I just do not think that public funds should be expended to promote any religion, regardless of what the particular religion is. Likewise, I do not think that public funds should be expended to suppress any religion. I am a live and let live sort of person, unless someone threatens me or my loved ones. The AFA, in my estimate, threatens all of us who do not agree with them.

My Little Town 20120704: Independence Day
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.
Before we get started, please allow me to wish our great Nation a very happy 236th birthday! Although the United States is not completely perfect, it is indeed a more perfect Union than had ever been conceived up to the time, and remains more perfect than any other. As long as the People are in charge, this will not change. Actually, I sort of begrudgingly look at 04 July as the anniversary, because I believe that the Nation actually came to be with the adoption of the Constitution of the United States on 04 March 1789, making it 213 years old, but the Founders chose 04 July, so I shall not argue too much. Actually, the Declaration of Independence was signed on 02 August 1776, but the wording of the document was approved by the Continental Congress on 04 July 1776. By the way, John Adams preferred 02 July because that is when the Congress voted to secede from the UK.
There were not very many formal observations of Independence Day in Hackett when I was little. Actually there were none. However, we still celebrated it in our own ways.

Pique the Geek 20120701: Fireworks Safety
This time of year I generally write about fireworks since they are integral to the celebration of Independence Day. I have written some rather technical pieces in the past, so this time I thought that it might be a good idea to write about some safety factors that users of consumer fireworks should observe. Even though consumer fireworks are designed to minimize risk of injury, there is a finite probability that accidents and injuries will occur.
Many of you know how much I enjoy the music of The Who, and I shall work them into this piece. It happens to involve one of the most treacherous pyrotechnic composition, flash powder. In a former life, I was a professional pyrotechnician, and I am still scared of flash powder.
Many accidents involving consumer fireworks are either personal injuries caused by negligence (often alcohol fueled), ignorance, or bravado (also often alcohol fueled). Many other accidents involving these products have to do with unintentional fires cause by firework use, storage, or transport.

Popular Culture (Music) 20120629: Live Moody Blues
We shall finish this rather long series with some live material from the canonical work of The Moody Blues. My aim is to present some of my personal favorites, recorded during the period that they were contemporaneous at the time that they were released.
There is a really nice set of videos on YouTube about the Isle of Wight festival in 1970, but they do not fit into the format for this series because they were excerpted from a documentary about the festival and have lots of talk and not much music. They are worth checking out, but this in not the venue. When you do, check out the first on when they have some cameras on the back of the sound system. Notice that many of those Hiwatt amps are labeled “WHO”, and a few are labeled “TULL”. Yes, they also played there. What a concert!
