motivation for learning the skill
I mean motivation for why somebody cares about the idea at all, but I think that is less strict so yes. A hole in theory or something emerging from an activity are perfectly fine. But there has to be something there.

So… From the publications, looks like he uses problem solving, not “having students actually think about math”.
You want students think about what exactly if you don’t give them an application?
Anyway, thanks, I’m listing his work as evidence supporting my claim.
Apparently knowing people learn differently and that mathematicians are a tiny minority is neoliberal…
unless their sun was the same temperature as Sol and their planet the same size as earth
Most other animals see different colors than we do, and they live under a star of the same temperature as ours, and in a planet with the exact same atmospheric composition.
The image is literally about the kind of thing the aliens would have in common.
You can decide on a language from that, but you will have to write down the definition of every word too.
When I got to asking “WTF does naturality even means?”, I decided to reread your comment from the beginning…
The amount of words in it that almost nobody will know the meaning is amazing!
If you are talking about school curriculum, nearly the entire population will keep not learning it as long as it doesn’t have some practical application so people can understand WTF the teacher is talking about.
It’s because the Sun is behind it.
In some ways, that lag is good. You can cheaply replace batteries with just a thermal mass.
But it’s not good enough to make up for the cost difference.
Generating electricity by boiling water used to be the cheapest option, but nowadays it’s a bottleneck that itself is way more expensive than the alternatives that people actually build.
It only got cheaper with time, though. It’s the alternatives (PV, wind, batteries, gas) that improved a crazy amount.
Turns out that sunlight is very cheap. You need a lot of efficiency to justify any extra cost.
No, neither will it be cheaper.
People stopped building those some years ago.
(But those incredibly expensive concentrators with a single tower are more efficient. Nobody is building those anymore either.)
Demons on one side, microorganisms on the other.
we could divert natural gas from other uses and have plenty for making ammonia. We also have other ways of producing hydrogen
We can’t do any of those in a scale large enough to replace the destruction and have it online for the next planting season on the North Hemisphere. Or the next one on the South Hemisphere either, btw. Or the following ones for each.
It doesn’t matter what time you think it’s the right one, the black hole will get it anyway.
Wow. So I went looking if people actually knew when our codon system appeared.
Turns out that there are 26 slightly different systems on Earth right now, and there are good reasons to expect random alien life to have a system that looks like ours, but is different enough to not be compatible.
It’s extremely unlikely that their DNA has the same translation semantics into proteins.
Well, the UUIDs for almost everything we use are galaxy-scale already. Astronomers just need to up those random letters a bit.
There’s a good reason sysv isn’t on the meme.
If you think it never broke, that’s because you weren’t doing anything different or creating anything that required it.
That said, systemd had a tendency to break even if you didn’t either. But nowadays the bugs are mostly fixed, and the stupidity is contained on parts people mostly don’t adopt.
