Off the top of my head, I can't think of any advance that didn't at some point depend on people just dicking around to see what they could see.

"What happens if we spin this stick really really fast against this other stick?"

"Cool! What happens if we put some dried moss around it?"

"That's nuts, man! Hey, I wonder what happens if we toss some of our leftovers in there?"

"C'mon over here, guys. You gotta taste this!"

At worst, a project like this keeps a lot of curious people in one place where we can make sure they don't cause harm with their explorations. At best, whole new industries are founded. Never forget that modern electronics would never have existed without Einstein and Bohr arguing over the behaviour of subatomic particles.

Say the actual construction cost is $100 billion over 10 years and operational costs are $1 billion a year. Compared to all the stupid and useless stuff we already spend money on, that's little more than pocket lint. We could extract that much from the spending of one military alliance and it would look like a rounding error. Hell, we could add one cent to the price of each litre of soft drinks, alcoholic beverages, and bottled water and have money left over.

That would be fine, except for the fact that some of the people in charge of setting curricula don't want that kind of education to happen. Where they are in favour of that, there are others working to get on school boards and other positions of power to explicitly battle such education.

I don't know much about the rest of the world, but Canada and USA both have increasingly powerful factions trying to take over school administration at all levels.

Here in Saskatchewan, we even have a Minister of Education who is deeply involved with the creation and support of "Christian Academy" schools that are little more than bible study groups.

Just be aware that enshittification is under way in this space, too.

I've switched back to using the library's own portal, even when it means forgoing digital media.

I'll give it a crack.

As others have hinted at, it's mostly about noise. The author puts noise in quotes when referring to those qualities of sound (and lyrics?) that are normally considered noise but are exploited for aesthetic purposes.

Thus, extreme volume and heavy distortion might normally be undesirable noise when trying to faithfully reproduce a sound, they are exploited by rock music in general and, in their extreme forms, by heavy metal in particular.

A metaphorical or all-inclusive understanding of noise can be applied to the various other aspects of music (rhythm, repetition, tempo, key changes, and even lyrics). The more of these aspects are affected (the more "noisy"), the "heavier" the result.

This was not addressed in the paper, but I think that the noise has to be introduced during the creation or performance of the music. If you play back a recording in ways that distort the signal or sound, you are probably getting noise, not "noise".

As a non-geologist living next to Lake Diefenbaker (the reservoir formed by damming the South Saskatchewan River), I also like geological history.

I have a standard reply for when I'm asked why we chose to move to this "treeless wasteland". "I look out at the flat horizon and see how the glaciers planed the earth the way a woodworker flattens a board. I look around me at the river breaks and see how the meltwater from retreating glaciers carved the earth away into shapes that defy imagination." I don't know accurate any of that is, but it fits my mental model of what I was taught in high school.

(What we call the river breaks are twisted and braided networks of coulees, some with sides so steep as to require mountaineering equipment. Most still run with meltwater in the spring.)

A lot depends on the boat, what it's used for, it's expected lifetime, and how long it stays in the water at any one time. For my purposes, future builds will use marine grade plywood (fir; nothing exotic) only for boats that I just leave in the water, and then only below the waterline. And maybe not even then. Depending on the boat, the price difference between marine and exterior grade might pay for a boat lift or rail system so that the boat never has extended periods in the water.

I agree. As a hobbyist woodworker and boat builder, I do everything with ordinary untreated construction lumber and plywood, reclaimed untreated lumber and plywood, and what I can get from people taking out trees.

Don't get me wrong. I love the look of tropical hardwoods, but I don't see how to justify their use at scale. And with however many billion people we have today, there is no such thing as small scale.

I don't think I've ever come across anyone else who thinks that the die was cast before the boomers and certainly by the time they came of age. I never tire of pointing out that Friedman, Reagan, and Thatcher and their cohort and most of their collaborators were not boomers. Nor are Poilievre, Trudeau, Scott Moe and theirs. Boomers are not without blame, but no 20th century generation is.

As a boomer myself, maybe I'm just looking to spread the blame. But in my rural community, it's the boomers who most reliably argue for environmentalism, debt control, and wealth distribution through public services.

It wouldn't have hurt my feelings any if you had kept it to 5! :)

You've got a couple on there that I wouldn't have included, but they are also in areas I haven't examined for impact, so ...

There are a couple where I actively disagree with you, but, again, my lack of expertise means I can't actually mount arguments.

That still leaves nearly a dozen. I'm not convinced that any one of them is sufficient on it's own, but any 2 or 3 in combination? Sure. I'm a doomer for a reason. :)

One of the reasons my personal focus was on climate change was that I thought properly addressing that would fix most of the rest as a side effect. I now think that pretty much all the disasters awaiting us have the same root cause: selfishness. As long as we are unable to care for anyone or anything other than ourselves, we will never solve any problem worth solving.

People talk about various tipping points for their pet disaster. I think the real tipping point happened in 1980.

Is there a site that does a variety of energy comparisons

Yes! Thank you. It's always nice to see other perspectives.

When I'm figuring the buoyancy of a 20 litre pail or, alternatively, how much it'll weigh when filled with sand, 3 is easier to work in my head for off-the-cuff estimates so I know about how many pails I need.

That said, I do typically use the π button on my calculator when it comes time to actually execute on the project. :)
