Dot AI Domains

"The Tiny Caribbean Island That's Making A Fortune From AI"

Back in the 1980s, when the Internet Assigned Numbers Authority was dishing out the geographic two-letter domains, Anguilla had the good fortune to be awarded .ai. That good fortune has turned into an actual fortune, with a huge influx in domain registrations over the past couple of years that have massively boosted the island’s economy.

The boom in .ai domain sales was triggered by the arrival of ChatGPT in November 2022. “In the five months after that, our sales went up by almost a factor of four,” Vince Cate, who manages domain registrations for the Anguillan government, told IEEE Spectrum. “Then they sort of leveled off at this new, much higher level. It’s just wild—we’re already like a third of the government’s budget.”

Feynman Reverse Sprinkler

"Mathematicians finally solved Feynman's 'reverse sprinkler' problem". (Via H.R.)

A typical lawn sprinkler features various nozzles arranged at angles on a rotating wheel; when water is pumped in, they release jets that cause the wheel to rotate. But what would happen if the water were sucked into the sprinkler instead? In which direction would the wheel turn then, or would it even turn at all? That's the essence of the "reverse sprinkler" problem that physicists like Richard Feynman, among others, have grappled with since the 1940s. Now, applied mathematicians at New York University think they've cracked the conundrum, per a recent paper published in the journal Physical Review Letters—and the answer challenges conventional wisdom on the matter...

One might intuit that a reverse sprinkler would work just like a regular sprinkler, merely played backward, so to speak. But the physics turns out to be more complicated. “The answer is perfectly clear at first sight,” Feynman wrote in Surely You’re Joking, Mr. Feynman (1985). “The trouble was, some guy would think it was perfectly clear [that the rotation would be] one way, and another guy would think it was perfectly clear the other way.”

Hsieh Forbes Column: How Much Basic Math And Health Statistics Should Legislators Know?

My latest Forbes is now out: "How Much Basic Math And Health Statistics Should Legislators Know?"

How much basic math do legislators know?

The Royal Statistical Society asked 101 members of the U.K. Parliament in 2021, “If you toss a fair coin twice, what is the probability of getting two heads?” The correct answer is, of course, 1/4 or 25%.

However, only 52% of the MPs got the answer correct. On the bright side, this is an improvement from 2011, when only 40% of the MPs got the answer correct.

My first thought when I learned about this study: I would love to know how U.S. congressmen would perform with the question...

Railway Workers Solve Trolley Problem

Railway workers solve the Trolley Problem

"'Slip the switch' by flipping it while the trolley’s front wheels have passed through, but before the back wheels do. This will cause a controlled derailment, bringing the trolley to a safe halt."

Some great comments in the original post: 

"In case anyone is wondering: yes, this is how train robberies operated in the Old West. Slip the switch after the locomotive passes by, passenger cars are stuck there. They could rob everyone and get away before the locomotive could even stop and reverse back to the passenger cars."
 
"And in case you were also wondering: yes, this tactic is still used by people stealing UPS packages from trains in various American cities today."
 
"This actually comes from railroad workers talking in comments on a fb [Facebook] group. I just made the meme for them. They were like 'those trolley memes are stupid, we have to do this in our railyard like once a week when some intermodal runs loose.'"

Have you ever wanted to give a child a gift that will force them to learn a hard, important truth about life that will scar them forever? Well look no further! Here are 3 ideas for how 3 popular children’s books could be adapted to teach children valuable life lessons...

Bad Software, Bad Convictions

"Fujitsu is sorry that its software helped send innocent people to prison".

According to a related BBC news story

Between 1999 and 2015, more than 900 sub-postmasters and postmistresses were prosecuted for theft and false accounting after money appeared to be missing from their branches, but the prosecutions were based on evidence from faulty Horizon software.

Some sub-postmasters wrongfully went to prison, many were financially ruined. Some have since died.

It has been described as the most widespread miscarriage of justice in British history, but to date only 93 convictions have been overturned and thousands of people are still waiting for compensation settlements more than 20 years on.

Politicians And Probability

In 2021, 101 members of the UK Parliament were asked "If you toss a fair coin twice, what is the probability of getting two heads?" The answer is, of course, 1/4 or 25%. FWIW, only 52% of the MPs got the answer correct

However, this is an improvement from 2011, when only 40% of the MPs got the answer correct.

First immediate thought: What would be the result if we asked US Congressmen the same question?

Second immediate thought: If that many legislators don't understand such a basic principle of high school math, are they qualified to be making big policy decisions that affect all our lives?

Lost City Found

"Huge ancient lost city found in the Amazon"

"It changes the way we see Amazonian cultures. Most people picture small groups, probably naked, living in huts and clearing land - this shows ancient people lived in complicated urban societies," says co-author Antoine Dorison.

The city was built around 2,500 years ago, and people lived there for up to 1,000 years, according to archaeologists.

It is difficult to accurately estimate how many people lived there at any one time, but scientists say it is certainly in the 10,000s if not 100,000s.

Navajo Nation And The Moon

"NASA responds to Navajo Nation's request to delay private mission placing human remains on the moon"

From my reading the Navajo Nation has asked NASA and the US Dept of Transportation to delay any private memorial space flights to the Moon which deposit human remains on the lunar surface. They claim this would be a "desecration of this sacred space."
 
NASA has said they have no jurisdiction over these private space ventures. The US government has "has formed an interagency group to review the Navajo Nation's objections". 
 
The private space company Celestis has said, "No individual religion can or should dictate whether a space mission should be approved... No one, and no religion, owns the moon, and, were the beliefs of the world's multitude of religions considered, it’s quite likely that no missions would ever be approved."
 
(I don't know how property rights and international law apply to the Moon, but I am inclined to site with Celestis on this one.)

SAT Vindicated

"The Misguided War on the SAT". (Via A.S.)

 A couple of interesting points:

 “Standardized test scores are a much better predictor of academic success than high school grades,” Christina Paxson, the president of Brown University, recently wrote. Stuart Schmill — the dean of admissions at M.I.T., one of the few schools to have reinstated its test requirement — told me, “Just getting straight A’s is not enough information for us to know whether the students are going to succeed or not.”...

[T]he data suggests that testing critics have drawn the wrong battle lines. If test scores are used as one factor among others — and if colleges give applicants credit for having overcome adversity — the SAT and ACT can help create diverse classes of highly talented students. Restoring the tests might also help address a different frustration that many Americans have with the admissions process at elite universities: that it has become too opaque and unconnected to merit.
