Two percent is only a little

A dam holding alumina, a chemical compound used in the production of aluminum, burst, but reportedly only 2% of the contained substance escaped. It’s difficult to imagine how this could be so considering that the dam appears to have failed catastrophically, at a corner, where you would least expect it to; but evidently alumina is not very fluid.

Two percent can’t be very much, right? For a sense of scale, try to find the heavy equipment in this photo.

Looks like a nice thick concrete dam. Think about this one if anyone wants to contain toxic by-product in fail safe dams near you.

Making music

I love what this artist can do on the fiddle and I wish I understood more (than a tiny bit) of what she is saying in this lesson. (You may want to skip to 1:58, when Lissa comes on.)

An awareness of my own ignorance does not prevent me from being skeptical of the method she teaches here. When people learn something enthusiastically (rather than being required to learn under a specific tutelage), it seems more common for them to learn by throwing themselves into the middle of the art–failing woefully, yes, but reaching for the whole. It has been widely noted that language is best learned immersively; and it doesn’t do much good to be able to pronounce a single word precisely.

Nobody, of course, tries to master every single possible nuance of an art at once; but I doubt that very many people learn by taking one atomic piece at a time. Breaking a skill down to its constituent pieces is a skill of itself and is demonstrated by people already proficient in the craft. Casual practitioners of any craft rarely cognitively interrupt their work into minuscules.

Fix it again, Bob

Chicago had a health problem, so they fixed it. All their sewage ran right into their drinking water, so they turned the river around and made a new hole in the lake.

They had to hurry before someone sued them for draining the lake. Or flushing their crap into the largest river in the United States.

It’s odd that for such a major geological, engineering, and social event, so little comes up on the top of Google. It’s attracted little (electronically published) attention relative to the magnitude of this alteration of nature. The Wikipedia article states, without citation, that the Asian carp that they are trying to keep out of the Great Lakes were introduced as environmental remediation.

Speaking of the environment, this blogger is concerned that ecosystems that “evolved in isolation” are now connected so that species that “simply were not meant to cohabit” are now in contact. Adaptation to changing environment is evolution; it isn’t anything else. Yeah, I know that humans are supposed to be changing things too quickly for evolution to work, but you don’t see anyone making plans to gradually change things, either. Evolution is supposed to have got us here, but now it must stop.

The whole saga — dumping sewage in a lake, reversing the flow of a river, using carp to clean algae, using poison to kill the carp (and whatever else), possibly sterilizing the sewage… it’s an unbroken story of unintended consequences and solutions causing more problems. But we clearly need more solutions! So don’t stop now!

This one news article seems to be primary source for the blogger and the Wikipedia story, so it sets the tone for all of the easy-to-find reading. And that is one of sneering disdain for the whole project combined with a general sense that sterilizing the sewage would solve most of the problems.

Doesn’t the very pattern of events here suggest that something unexpected and undesired will follow? Shouldn’t we be talking in terms of cost and benefit rather than obvious solutions?

I am just amazed that the tourist boat ride on the river focusing on architecture covered almost all of the same material. This is obviously not a subject of popular debate.

Animals thinking in plain sight

First we have the bear who thinks, “Crap, I’ll never be able to drag the whole thing far enough through that brush to get away from the nosy people, I’ll have to cut my losses and eat the most nutrient-rich part.”

Then you have the gangland showdown where a some punks are trying not to be too obviously salivating over the the moose brother who is just rollin’ but looks like he got some heat, too. The moose tries to look like he don’t care nohow. But he don’t get no drink, neither.
