Only the grains that are knocked out of the box don't get played any more.

They get to play in a sandbox designed for them. They're taught how to play in the sandbox, and are given the toys to play (roads, electricity, raw materials for example). We get to be the sand.

Citizens United

Corporations have been 'people' since the 1886 USSC decision in Santa Clara County v. Southern Pacific Railroad.

Yet somehow, unlike most people, they've escaped having to go to jail when they commit crimes. I'd call that an unfair advantage.

158 families isn't much to feed 300 million starving people. We need rules on who gets to eat the 0.01%

It is very hard to grow food outdoors in either case. Underground the temperature is fairly stable at about 30+°F. If that's allowed, and I can manage how to grow food underground, then from experience I know I can easily survive 9°F and spend a LOT more time outdoors than at 100°F

Nuclear is: very slow to make, very expensive, generates dangerous waste, invites proliferation.

Wind and solar are quick, relatively much cheaper, create little waste. The sun is forever.

Personal transportation needs a complete redesign. Burning fossil fuel at 20% efficiency (80% waste) to push a 4000lb. vehicle with a 200lb person in it is insane. Personal electric vehicles of 200-300 lbs tracking defined lanes at 20mph under computer control would take care of 80-90% of urban travel needs. And greatly reduce the number of roads needed.

 

"In a study published in Nature Communications, the researchers reveal an elegant molecular mechanism that acts like a GPS coordinate system for regenerating cells.... the puzzle was how the cells in the regenerating limb-stump controlled their levels so precisely to know exactly where they were on the axis from shoulder to hand.”

Remembered this song today after running across some lyrics. Damn.

[Verse 3] I'm sick to death of seeing things From tight-lipped, condescending, mama's little chauvinists All I want is the truth Just give me some truth, now

[Verse 4] I've had enough of watching scenes With schizophrenic, egocentric, paranoiac, prima-donnas All I want is the truth, now-now Just give me some truth

No, I wouldn't assume non-convergence either ... NOR would I assume that that AI didn't just grab that 'high-level' 'Elaboration' from some site ... without a citation.

(Very human ... Lots of people use quotes to sound smart, hoping they'll get away with it. LAWYERS! Ministers! Presidents, even! )

One less formal way of looking at it is this: there are an infinite number of multiples of 35. starting with 35, 70, 105. Add 6 to each of the odd multiples. 35+6=41 (prime); 105+6 = 111 (prime). With an infinite # of candidates, you've gotta get to an infinite number of solutions (for some value of infinity!)

As for that Dirichlet stuff, it's way beyond any of the useful stuff I learned too.

Very nice. Makes my generic LLM look like a lumpkin. I'd heard that mathers were impressed by some of them.

Hypercard (Bill's baby) was great; it's HyperTalk was a very cool alternative for many "usual" programming tasks. After it died, I kept using it until the web took off ... then, in a couple of hours, I used HyperTalk to make an app to convert my stack content into HTML pages. If it had only had networking built in, it'd probably have become the (much better) basis for the Web.

I came to a conclusion about GPT (which is very good with English on most topics) when I asked it how many prime numbers, when divided by 35, leave a remainder of 6. It quickly and confidently said there were none. It hadn't even tried. The correct answer (there's a proof) is: an infinite number.

Two months later it answered that there were 3. Closer ... but no cigar

 

Absolutely needed: to get high efficiency for this beast ... as it gets better, we'll become too dependent.

"all of this growth is for a new technology that’s still finding its footing, and in many applications—education, medical advice, legal analysis—might be the wrong tool for the job,,,"

 

"The exercise was held from May 8 to 9, 2024, at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and at a Federal Emergency Management Agency (FEMA) site in Denver, Colorado."

Article refers to a PDF of the report it's based on:

Green Gravity's renewable-powered technology stores energy by lifting heavy objects up a mineshaft.... It calculates it can store two gigawatt-hours of energy from the sites surrounding Mount Isa.

 

"This road is long, and much of the map remains blank. The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons."

 

It is estimated that 4 billion tons of cement are manufactured each year. To speed up CO2 uptake, "instead of mixing calcium oxide with sand, they mixed calcium oxide with another mineral composed of magnesium and silicate ions. The heat catalysed an exchange of ions, forming magnesium oxide and calcium silicate: alkaline minerals that react quickly with acidic CO2 in the atmosphere." Far quicker than most concrete, anyway...

Estimated heat energy in upper 10km of Earth's crust: 1 million billion Gigawatts

 

The period occured in 2024 between late winter and early summer. "Compared to the same period in 2023, solar output in California is up 31%, wind power is up 8%, and batteries are up a staggering 105%."

One of the paper's cowriters is Mark Z. Jacobson, professor of civil and environmental engineering and director of the atmosphere/energy program at Stanford University.

 

""Too often over the last decade, courts have dismissed lawsuits against the oil and gas industry by saying that the issue of climate culpability should be decided by legislatures. Well, the Legislature of the State of New York – the 10th largest economy in the world – has accepted the invitation...."
