Pique the Geek 20120205: Carbon NMR Spectrometry
NMR (Nuclear Magnetic Resonance) spectrometry is one of the big guns in organic chemistry and biochemistry for determining how atoms are strung together in molecules. There are many different kinds, but the two of greatest utility to chemists are proton NMR and carbon-13 NMR. A friend of mine asked me for some help for his daughter who is studying the subject in Organic Chemistry right now, so I thought that I might as well use it as a topic for this series.
Before we get deep into the subject, note that some authors refer to NMR spectrometry and others to NMR spectroscopy. I prefer the former term because the connotation of spectroscopy, to me at least, has to do with lenses, prisms, and diffraction gratings, making it an optical method. There are no analogous devices in NMR, so I prefer spectrometry.
All NMR has some features in common, so we might as well cover the basics first. By the way, this has nothing to do with nuclear energy, and the only radiation present is in the radiofrequency range, so it will not fry you.
This is heavily connected with quantum mechanics, but I shall try to use analogies that are more easily visualized than a bunch of equations. I do not intend for this to be a graduate level abstract.

Popular Culture (Music) 20120203: A Brief History of The Who. 1976
Last time we looked at 1975, and if anything 1976 was a bit more settled for The Who in some respects. Most of their time was spent doing a huge tour, with multiple Atlantic Ocean crossings. There were a couple of reasons for that.
Likely the largest reason was that the dispute betwixt the band and Kit Lambert was still in litigation, and it was sort of difficult to release old material, and new material was still being written. They were stuck in a way just to perform live. That was to my personal advantage, and more on that is to come later.
One the whole, the band were probably at their best musically in 1976. The exception was Moon, who was beginning to accelerate his decline both personally and musically, but that did not come out until sort of late in the year.

My Little Town 20120201: Raising Children Then and Now
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.
There is tremendous betwixt how children were raised 50 years ago and now, whether in a little town or a large city. Tonight we shall contrast how I was raised to how children today are. I am not talking so much about the cultural evolution as I am the technology available, but the two are quite entangled.
This is going to be sort of a stream of consciousness set of recollections about how we did things back when I was little and how it is done now. Most of the topics are everyday activities that families do routinely.

Pique the Geek 20120129. The Things that We Eat. Milk
Of all foodstuffs, milk is unique in that it provides all of the nutritional needs for infant mammals. In addition to nutrition, it also supplies essential antibodies the first few days to newborns. Milk is unique to mammals, and is one of the reasons that mammals had the evolutionary advantage that they had when they arose during the age of reptiles.
However, humans are also unique in that we are one of the few mammals who continue to take it after infancy, and the only species that continues to take it after adolescence and into adulthood. Milk is far from the perfect food for adults, but certainly can be part of healthy diet.
Humans are also unique in that we are the only species that takes milk in a natural setting from other species. By that I mean that we actively collect it, not like giving the cat a saucer of milk. The nutritive value of milk is species specific, and our habit to taking cows’ milk (for the most part) is quite unnatural.

Popular Culture (Music) 20120127: A Brief History of The Who. 1975
If 1974 had been a bizarre year, 1975 was more structured in some ways. Several events happened in 1975 that were important to their financial security, for both good and ill.
The most significant events of 1975 were the release of the motion picture Tommy, the release of The Who by Numbers, and the beginning of a huge tour of Europe, the UK, and North America. Now, there were certainly some problems associated with all three of these events, but 1975 turned out to be a pretty good year for them.
However, Townshend was not a really good frame of mind for much of the year. He was very unhappy with his place in the band and whether or not there even should be a band called The Who, at least with him in it. It is sort of an interesting turn of events that kept them together, and there is more on that later.

My Little Town 20120125: My Cars
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.
Last time we talked about some cars that I helped my father restore either for resale or for keeping. Cars seem to be a popular topic here, so we shall continue this theme about cars that were mine back in the day when I was growing up.
I have also decided to define my “growing up” period from birth to when I was 20 years old. I have chosen this somewhat arbitrarily, but since I married at 20 it seems to be a pretty good choice. Realistically, I do not think that anyone is grown up at 20, but I have to make some sort of demarcation.

Countdown without Keith Olbermann 20120123
What has happened to Keith Olbermann?
I know that he has some health issues, but for Chrissakes, he is younger than I am, and I NEVER miss a post unless something really important is happening. And I do not make any money posting here, either.

Pique the Geek 20120122: Chlamydia, a Serious STI
Last time we talked about trichonomiasis, a sexually transmitted infection (STI) that often produces no symptoms. Chlamydia is another STI that often causes no symptoms, at least initially. We shall investigate this condition this week and then move to topics other than STIs next time.
This infection is usually caused in humans by the bacterium Chlamydia trachomatis and is found only in humans. Unlike trichomoniasis, women are more often asymptomatic than are men. Estimates are that around 75% of women present with no symptoms whislt around 50% of men do have symptoms, almost the opposite from our infection of the week last time.
Although this is a serious subject, let us keep it a bit light. After the fold in a song by Todd Rundgren called “You Left me Sore”. Although most likely written about gonorrhea, it is still apt in this case.

Popular Culture (Music) 20120120. A Brief History of The Who. 1974
Whilst 1973 was a roller coaster year, 1974 was downright bizarre. The main reason for that was the extreme domination of time and energy by the film version of Tommy.
This is as close to writing a piece about that motion picture as I am going to get, because I really did not like it very well, and though that it was just a caricature of the outstanding album. I also blame that motion picture in part for the demise of Moon a few years later, mostly because of Moon’s relationship with Oliver Reed.
This year also provided a dearth of material from the band, with only two singles and one album being released. There were also personal conflicts, particularly betwixt the band and their management.

My Little Town 20120118: Old Cars
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 dad was passionate about old cars. As far back as I can remember he would restore them, some to keep and some to sell. When we moved to North Little Rock when I was three, he had been working on a 1919 Model “T” Ford Touring. He put it on a trailer and brought it with us so he could finish it. There will be more on that car later.
I also remember him with a 1923 Studebaker Touring, a 1949 Willys Jeepster, a 1955 Ford Thunderbird, and his pride and joy, a 1941 Packard 110. I helped with some or all of the restorations on all of these cars, but was too little to do much with the Model “T”. However, there are more memories associated with the cars.
