Up the Danube: Prague–Always Cloudy, Never Grim

Ahhh, Prague!

That seems to be the prevailing sentiment of everyone who had been there, when we mentioned we were planning a visit. And who looked at my early Facebook photos. And who heard me mention the word.

We are touring bits of Central Europe for the next three weeks–I think of it as Eastern Europe–but Google says otherwise. We start in the Czech Republic, move to Hungary, then up the rivers through Germany to Amsterdam. I should think 3 or 4 blogs ought to cover it, but let’s see. There are lots of tours scheduled, so not sure when I’ll write. But a lady at dinner last night had just done the tour the other direction, and she said, “There a lot of locks.” Stay tuned for pictures of locks.

The Folly of Greenlandia

Last month when I was writing about Rubber, I learned about Fordlândia, a rubber plantation/utopia that Henry Ford built in the Brazilian jungle. My word count for that post was too high, so I left out the story. But it’s been rattling around in my head ever since, pinballing to the top every time I read another story about this administration’s obsession with Greenland. Plus, that Santayana quote, the mantra of historians, constantly reminds me to study the lessons of the past. Anybody remember maps which referred to the Belgian Congo? Ever hear of Minimata disease?

Corporations and governments–that is, corporations whose security adopts uniforms and carries a flag–often get the bright idea to get resources cheaply from places where the scrutiny is lax. Of course, corporations and governments aren’t entities unto themselves. It’s the leaders who come up with cockamamie schemes of exploration and exploitation, schemes which lead to environmental devastation, mutilations, genocide. Often, costs vastly outweigh the benefits.

I realize that the moral reprehensibility of those first three evils ought to sway the argument against exploitation, but there’s no moral reasoning, sometimes, with corporations, which suddenly become faceless when there is wrongdoing. I was nurtured at a tender age on cost-benefit analysis, and I sometimes find it makes a persuasive argument when other arguments won’t do. In that spirit, I’d like to offer a few examples from history as reason to pause before we start invading and strip-mining Greenland.

A Disjointed Post

Rendered by Google AI, this Frankenstein robot drawing is the only creative AI used here

Surgery is the topic of today’s post, namely because I had shoulder arthroplasty last Tuesday. The technique was reverse shoulder replacement and, as you ask, what is that? be assured that I will get there. We have to cover a little anatomy, anthropology, Popular Mechanics, history (of course), and technology along the way.

Fish Gotta Swim, Horses Gotta Run, Humans Gotta Throw Spears

Let’s talk about joints, specifically shoulders, ball-and-socket joints, and the term synovial. I had originally thought that fish had no ball-and-socket joints, and I was going to claim that it was the reptiles, crocodiles crawling out of the water, who began to develop those movable arm and leg joints rather than fins. But it turns out that, even at the beginning, fish had some types of ball-and-socket joints in their jaws, in their vertebrae, and even in their fins.

Synovial=(Greek) put together+egg=the shape of certain joints

The word synovial is important here because it means that within rigid bones, there is a hollow part and a bumpy part that fit together. Even with fish, there were hollow/bumps that fit together in fins and jaws which allowed for more flexibility and rapid movement. When reptiles developed the ability to walk on land and swim in the water, those fins turned into longer bones with multiple places for movable joints.
