“The Star Mangled Spanner”
Dunning-Kruger thinking is running riot through the trump administration all the way to the top.

Today I Learned
I have a long time friend whose dad had a couple of small shops repairing and selling domestic electric goods like these. He told me back in the 90's that these rarely came compared to other makes. They would suck up a brick if the pipe was wide enough. They have a good spares system as well.

Chat with WILL-AI. Invitation to participate in the field test of custom AI as science communication tool.
That would seem the obvious path, otherwise there is no verifiable reference to test its accuracy with. AI slop being a known factor.

The best vacs imo called 'Henry's' have a manual rewind on the top.

Messages to the president...
Iran and Oman are going to charge toll fees for passage through the strait for the next two weeks, where it was free before. The "art of the deal", eh, Mr President?

Yep. There is a tendency to select arbitrary historical dates in isolation that support and justify some government military action.

Now for some REAL science
How do they account for the food-type variable? Some generate more stinky farts than others. What is the marker chemical that defines what is stinky? A smell is in the nose of the beholder.

Why is oxiadation is bad?
That might be dimethyl sulphide produced by marine algae. It can nucleate rain drops. I think it's how clouds are formed over the colder sea areas; sub12c water temperatures.

1200 years of Cherry Blossom season dates support climate change data
It appears so. I found this graphic of how tapping season is shifting earlier with rising average temperatures over time. https://www.climatecentral.org/climate-matters/maple-syrup-season Charts I've found so far go back to the 70's.

Why is oxiadation is bad?
Yes, a lot better. They were what we called 'rust buckets' after a few years then.

Why is oxiadation is bad?
IIRC, in the 70's and before, cars didn't last much beyond 10 years in the UK, when rust became a critical problem.

1200 years of Cherry Blossom season dates support climate change data
This chart of Japanese cherry blossom seasons going back to 812AD seems to support the onset date of the current climate change cycle as happening during the industrial revolution. of the mid-1800's.

Scientists discover liquids can fracture like solids under extreme stress
The mirror segment actuators are controlled by software which can constantly adapt their configuration in real time to the prevailing seeing conditions affected by localized changes in atmospheric density. They aren't set-and-forget optics. The ground-based adaptive telescope views can apparently rival space-based telescopes in image quality.

Reviving dead batteries
Yes, you are probably right.

Reviving dead batteries
Doubt that they charge to 100%, more like 95%. 4.1v is 'full'.

English...
Yes, that illustrates the fluidity and kaleidoscopic nature of English evolution perfectly.

English...
It means the English don't have rules that stay inert over time. They change according to the needs and social whims of the era. Common contemporary usage of a word becomes its de facto definition. English dictionaries are records of historical usage, and not authorities. A word's meaning may change over time due to a change in popular usage. Does that make sense?

Right.

Reviving dead batteries
It turns off permanently by design if the residual cell voltage drops below about 2.7v. The normal operating voltage is 3.2v - 4.2v. The 3.2v point is the arbitrary 'zero' point. At some point just below that, the battery is considered to have 'failed' and the circuitry disables it. If the voltage further drops below 2V, the lithium can turn metallic and form web-like structures, which can short-circuit the cell, heat up rapidly and go into thermal runaway. I've seen it twice and nothing can stop it. It's like a jet engine.
