An Anesthesiologist Discusses Gunshot Wounds and Calibers

Very interesting video discussion of gunshot wounds by Dr. Andreas Grabinsky (34:04), who practices in Seattle.  From the description.

He provides a interesting look at ballistics from their perspective. Essentially he considers a handgun wound,..and that common calibers lack power. He also makes distinctions between the types of damage seen from the traditional rifle round and the modern small caliber high velocity rounds.

...this is not a direct 9mm vs .45 comparison. However it does illustrate how silly the 9, .40, .45 debate is. The Dr. clearly shows the general lack of “power” of the common handgun round. Popular modern service calibers have nearly identical performance and are all built to (and do) perform within the same IWBA and FBI specs. Yes, on paper some rounds do have a ballistic edge over others, often at the expense of capacity, recoil and follow up speed. You can see the insignificance of arguing over 15, 20 or 50ft Lbs energy difference in cartridges making 400- 450ft lbs of energy when a .308 makes nearly 3,000ft lbs. That pretty much puts the insignificance of a 30ft lb difference into perspective.

Be advised, that there are some graphic portions in this video, but it is a very interesting 34 minutes and 4 seconds.

Ignore Those Seasonal Road Signs

Most of the Mason Tract Pathway, which harbors a lovely 14 mile stretch of the South Branch of the Au Sable river which I love to fly fish during the Spring, Summer and Fall, can be inaccessible in the Winter months of the year when the snow comes often and deep.  You can get back into the Mason Tract rather easily via a snowmobile in the Winter months, or on cross country skis if you don’t mind working for this access, but taking a truck back into the Mason Tract during the Winter months is not without risks.  I know a couple of folks who made it into the Mason Track in their four wheel drive truck during the thick of Winter, but, were unable to make it back out due to a compounding comedy of errors, which included them having to hike about 4 miles back to a main road, while wet and cold, which is one of the reasons I typically do not fish the Mason Tract in the Winter, besides the reasons of I do not own a snowmobile, and I’m not interested in cross country skiing in.

Here’s something that could change all that.  It’s called Track N Go, by AD Boivin, and its a ‘‘wheel driven track system for pickup trucks.’‘

Here’s a 5:18 YouTube video of Track N Go.  I’m quite interested in seeing this product come to the marketplace, and I will seriously consider acquiring such a novel system for my pickup truck, and not just for Mason Tract fly fishing opportunities in the Winter, because there are many seasonal roads in my neck of the woods that I would also enjoy traveling down when the snow is deep.

Patchwork Quilt Of Bookmarked Links

While I was contending with technical problems with this here blog, and other pressing family matters, I accumulated a patchwork quilt of bookmarked links which had caught my eye.  Each of the links stimulated a thought or two in my mind which I had hoped to post on individually, but due to additional calls for my time or services at the moment, I present these bookmarked links to you in a patchwork quilt style in a running commentary format.

The recent announcement that the bones of King Richard III had been positively identified made almost every news feed and blog I frequently visit.  The story is indeed interesting, and the find of Richard III’s bones was a fine bit of sleuthing, but the wide coverage this story received makes me wonder why the story of the Warsaw Ghetto archives, which were compiled, buried under the Warsaw Ghetto, and then recovered after World War II did not receive as much MSM coverage, especially when you consider that portions of this archive are still understood to buried under the city of Warsaw.  I’d like to see a bit of sleuthing applied to these missing portions of the Warsaw Ghetto archive, with as much enthusiasm as was expended in the hunt for Richard III’s bones.  On a related note to the Warsaw Ghetto archives, is the story about Yale’s compilation of Shoah testimonies titled What the Dead Have To Say To Us, and which asks Are we listening?

Then there’s this piece in the New Republic, a bit of evolutionary whimsy under a headline which reads Why Do Grandmothers Exist?, which is written with a nod to the point of view of Dawkin’s selfish gene hypothesis.  The question “is not as unfeeling as it sounds,” the article informs us, though I would say that asking such questions paves the way for asking even more damning questions with answers which could be quite dangerous, and which goes far in explaining why articles are written with titles such as When Beauty Is Not Truth and Humanity Will Come to an End.  Then What?  A fine illustration of the ideas inherent in these pieces can be viewed and read through at American Digest, in a piece Gerard Vanderleun posted and titled Brave New 1984: We Live in the Orwell|Huxley Hybrid.

An article on Dr. Oz also caught my eye, The Operator: Is Doctor Oz Doing More Harm Than Good.  This article is rather long, but interesting, and my favorite line in this piece is when they refer to Oz as “Welby 2.0.”  As in Marcus Welby.  The reference seems quite apt.  Reading of Oz’s penchant for promoting some healthcare practices, fads, which seem to have no data to support their efficacy, made me wonder if an upcoming Dr. Oz Show will feature a segment on Getting Fit Fast: Inactive People Can Achieve Major Health and Fitness Gains in a Fraction of the Time, and if Oz has ever done a show on the subject of prayer, such as discussed in a Wired piece titled A Prayer Before Dying.

A small business news piece which I enjoyed was Ed Driscoll’s Mugged by Reality, the Eternal Recurrence.  Reality does have a way of mugging you, at least if you’re prone to residing in the utopian world of liberal politics and higher education as they currently exist.

In the lost and found category, I recommend the story on the Russian family which lived alone, unmolested, and unknown for 40 years, from 1938 to 1978, in the taiga of Siberia.  The story is titled For 40 Years, This Russian Family Was Cut Off From All Human Contact, Unaware of World War II.  Quite interesting.

To close this post on a more positive note, I point you to an animated short, posted by Theo Spark, which is titled Paperman (6:35), which is a wonderful little love story, and remind you that bigger isn’t necessarily better (1:16 viddie).
