Certainly you can. Probably in less than 5 seconds, or you wouldn't be reading this blog.
But... one-fourth of incoming University of California San Diego freshmen taking a placement exam last year failed to solve for the x.
And... 3/5 of them failed to round 374,518 to the nearest hundred.
"... it is so jarring to read a lengthy new report from UCSD’s Senate-Administration Working Group on Admissions that says many students can’t answer simple math questions. “Between 2020 and 2025, the number of students whose math skills fall below middle-school level increased nearly 30-fold, reaching roughly one in eight members of the entering cohort,” it stated.Some 25% of students in need of remedial math training couldn’t figure out the answer to this equation — 7 + 2 = blank + 6 — the sort of problem that California first-graders are expected to master. And 61% were unable to round the number 374,518 to the nearest hundred — a basic task third-graders are drilled on..."
But the last cause on that list — high school grade inflation — is something that UCSD can’t fix. It is part of a far-reaching educational crisis that demands a much broader response.The report said even the students admitted in 2024 who were most in need of remedial support had high school math grade point averages of better than 3.6 — and the difference in such GPAs between the least and most prepared entering students was very small.
If you're interested, here is one Math Placement Exam from UCSD, which you can take at home privately and for free. It seems to start easy and get harder as you go along. I didn't see these particular questions on this particular placement exam.
Related: Over the years I have hired a number of bright young neighborhood high schoolers to help me with yard and garden chores, and I sometimes challenge them with math and geometry puzzles from the mathematics category of this blog to ponder while they walk in diminishing circles behind a mower, or to take home to work out. Last year I messaged a new puzzle to a high-school junior. The correct answer came back in a few hours. I told him I was impressed. He said he and his friends couldn't figure it out, so they plugged it into ChatGPT...
Neuston, also called pleuston, are organisms that live at the surface of a body of water, such as an ocean, estuary, lake, river, wetland or pond. Neuston can live on top of the water surface or submersed just below the water surface. In addition, microorganisms can exist in the surface microlayer that forms between the top- and the under-side of the water surface.Neustons can be informally separated into two groups: the phytoneuston, which are autotrophs floating at the water surface including cyanobacteria, filamentous algae and free-floating aquatic plant (e.g. mosquito fern, duckweed and water lettuce); and the zooneuston, which are floating heterotrophs such as protists (e.g. ciliates) and metazoans (aquatic animals).The word "neuston" comes from Greek neustos, meaning "swimming", and the noun suffix -on (as in "plankton"). This term first appears in the biological literature in 1917. The alternative term pleuston comes from the Greek plein, meaning "to sail or float". The first known use of this word was in 1909, before the first known use of neuston. In the past various authors have attempted distinctions between neuston and pleuston, but these distinctions have not been widely adopted. As of 2021, the two terms are usually used somewhat interchangeably, and neuston is used more often than pleuston.
In the hospitality industry, it is used to indicate that an item is no longer available, traditionally from a food or drinks establishment, or referring to a person or people who are not welcome on the premises. Its etymology is unknown, but the term seems to have been coined in the 1920s or 1930s.
"As the stockpile kept growing, the Obama administration began talks to curb it. In 2015, Iran and six nations led by the United States reached an accord that limited the purity of its enriched uranium to 3.67 percent and the size of its stockpile until 2030... Iran lacked a single bomb’s worth of uranium in 2018, when Mr. Trump withdrew the United States from the pact and reimposed a series of tough economic sanctions."
In economics, demand destruction refers to a permanent or sustained decline in the demand for a certain good in response to persistent high prices or limited supply. Because of persistent high prices, consumers may decide that it is not worth purchasing as much of that good, or seek out alternatives as substitutes.
Oxford Economics has it modelled. Oil at $150 plus for four months, global inflation back at 7.7 per cent close to the 2022 peak, world GDP growth slowing to 1.4 per cent for the year. Australian recession sharpest since the early nineties. None of this is fringe analysis. This is the orthodox economic forecasting houses now openly publishing recession scenarios with a straight face.And the equity markets are still being held up by the AI fever dream. A handful of US tech billionaires playing a hyper-financialised game of chicken on multi-trillion dollar valuations underwritten by an artificial intelligence investment bubble that still has not delivered the productivity gains it promised, and is openly built on the premise of replacing every working person on the planet. When the energy shock fully filters through into demand destruction, into corporate earnings, into job losses across logistics, transport, agriculture and manufacturing, the unwind will not be gentle. Your super fund’s overweight position in Nasdaq tech is going to find out the same way it did in 2008.The convergence is the real fucking story. Energy shock plus inflation shock plus AI bubble plus a US president actively breaking the global trade system with tariffs plus a global central banking response that has run out of room. We are looking at conditions that could make 2008 look like a kindergarten scuffle. It is not impossible to talk seriously now about Great Depression two point oh. The brokers laughing that off three months ago are now on speed dial to their compliance departments.
LIHOP ("Let it happen on purpose") – suggests that key individuals within the government had at least some foreknowledge of the attacks and deliberately ignored it or actively weakened United States' defenses to ensure the hijacked flights were not intercepted. Similar allegations were made about Pearl Harbor.MIHOP ("Make/Made it happen on purpose") – that key individuals within the government planned the attacks and collaborated with, or framed, al-Qaeda in carrying them out. There is a range of opinions about how this might have been achieved.
“Cyclone” is the word L. Frank Baum chose to describe the Kansas storm in his story, although he clearly meant “tornado.” Shortly after THE WIZARD OF OZ book first appeared in 1900, Professor Willis L. Moore, then Chief of the United States Weather Bureau, wrote Baum’s publishers to urge them to correct the inaccurate usage. He received a response from Frank K. Reilly of The George M. Hill Company, offering that the change would be made in the next edition. This, however, was never done, and any who purchase a copy of THE WIZARD OF OZ reprinting Baum’s original language will find that “cyclone” remains, again and again – as colloquial and as factually incorrect as ever. (MGM got around the issue in the movie by having Bert Lahr exclaim, in idiomatic fright, “It’s a twister! It’s a twister!” Later on, however, the screenwriters were loyal to Baum, and Judy Garland’s Dorothy explains to Toto, “We must be up inside the cyclone!”)
That's not going to do much to heat the space because a slant fin radiator is meant to move air by convection. The normal installation is down low near the floor, not up high. Also usually below a window. They work by heating the cool air that's coming off the window and falling down on them.
"Meghan McCain bleated out, “I don’t want to hear one more fucking criticism of Trump’s new ballroom at the White House,” which — briefly — seemed likely to be the most vacuous comment of the evening. Even by Meghan’s increasingly wooly standards, using the shooting at the DC Hilton as a pretext for building the $400 million ballroom seemed like a non-sequitur.
But it was quickly followed by what I am sure was a completely spontaneous and not at all coordinated flood of almost identical comments from the MAGA toady gallery, which didn’t feel the need to change the wording or the message.One does not have to be a member of the august punditocracy to note that MAGA reacted this way because MAGA was told to react this way..."
Phishing scams involve “two distinct paths,” Ms. Tobac added. In one, the recipient is served a link that turns out to be dead, or so it seems. A click activates malware that runs silently as it gleans passwords and other bits of personal information. In all likelihood, this is what happened when Mr. Lantigua clicked on the ersatz invitation link.Another scam offers a working link. Potential victims who click on it are asked to provide a password. Those who take that next step are a boon to hackers.“They have complete control of your email and, in turn, your entire digital life,” Ms. Tobac said. “They can reset your password for your dog’s Instagram account. They can take over your bank account. Change your health insurance.”
The color is "American flag blue. That’s the color of the industrial-grade pool topping that is going to applied to the Lincoln Memorial Reflecting Pool as part of renovations on the century-old monument."
Umm.. this part of the approved restoration of the reflecting pool, kicked off in 2010 [Obama administration] and again in 2023. The reflecting pool was built on marshland that had been drained and supplemented with dredged material from the Potomac River. Constructed without an underlying support structure, the pool sat directly on this soft ground. And filled with over 6 million gallons of water it, it started sinking into the ground and leaking. In the 1980s' they poured concrete into the pool to try to stablize the pool. But by 1986 it was losing 500,000 gallons of water per week. Between 2010-2012 they did major repairs, but the repairs havent held.A plan was proposed in 2023 to tear out the reflecting pool and totally replace it for $301 M. However, an alternative plan to coat the bottom of the pool with a standard industrial pool coating to seal it was devised. That is estimated to come out to $2-8 M total, and save up to $1 M in annual costs to repair and refill the reflecting pool. And that's where the blue color comes from -- standard pool bottom sealant color, and picked to reflect the sky since its a reflecting pool.

"They’re called Dutchmen, they’re shaped like footballs to cover long knots or splits.... That’s not a Dutchman. Dutchmen are also called bow ties because that’s what they are shaped like. This is a biscuit.... No. It’s a Dutchman. A Dutchman can be any shape and is used to hide blemishes. A bow tie is a Dutchman key and is used either for decoration or to stop cracking. This may be the same shape as a biscuit but it’s not a biscuit because of how it’s used. Biscuits are for joining wood... Can confirm, I work maintenance at a fulfillment center and if a conveyor belt suffers damage one of the options is to cut out the damaged section across its entire width and then lace in a length of new belt to fill the gap. We commonly do 8 ft Dutchmans to allow the entirely of the patch to be inside the pulleys of the main drive and still have both lacing visible and accessible, should the lacing fail then the Dutchman isn't all wadded up in the drive..."
"Knots in wood are much more dense than the stringy, normal wood. When they make plywood, they layer thin strips (plys) of wood together and glue them to one another like a wood-and-glue sandwich. The problem arises when there is a dense, brittle knot on either of the two exposed plys on the plywood sheet. Shaving a slice of a dense knot gives you a super brittle portion that often ends up crumbling out in crumbs.Think of it like having a sheet of paper with a small section of equally as thin glass embedded into the paper. You can bend the paper portion, cut the paper portion easily with scissors, but the little glass portion has different properties. It's more dense, but you can't bend it or stress it or else it will shatter."
Call was lost, as usual.Ok.

This was not just a car. It was an art car — a vehicle transformed into a kinetic sculpture, built from imagination and, often, from what others had thrown away.“I can’t drive past trash without pulling over,” said Mr. Polidore, 50, a longtime elementary school art teacher who writes art curricula for the district. “When I’m stuck in that hellacious Houston traffic, I’m scanning the side of the road for any parts of cars that have gotten thrown off in wrecks and I’m grabbing them.”...The rules remain minimal. “Whether it’s been painted, welded, sculpted, dropped, chopped, beaded, smashed, crashed, lit or lifted, art cars come in all shapes, sizes and forms,” read this year’s brochure. “The only rule is that it must roll!” And across the city, in garages, driveways and schoolyards, artists have been working for months to ensure that theirs will.But what might make Houston’s art car parade so special is the fact that many of the artists are children... Over 50 of the cars that roll on Saturday will have been made in Houston classrooms, a striking fact at a time when arts funding in schools continues to shrink...In Houston, where driving is nearly unavoidable, the art car offers a kind of inversion, a reminder that even the most ordinary object can be remade into something strange, expressive and communal.Or, as Ms. Soto put it: “Art cars are chaos. Good chaos.”
A US appeals court on Friday declared a nearly 158-year-old federal ban on home distilling to be unconstitutional, calling it an unnecessary and improper means for Congress to exercise its power to tax.The fifth US circuit court of appeals in New Orleans ruled in favor of the non-profit Hobby Distillers Association and four of its 1,300 members.They argued that people should be free to distill spirits at home, whether as a hobby or for personal consumption including, in one instance, to create an apple-pie-vodka recipe.The ban was part of a law passed during the US’s post-civil war Reconstruction era in July 1868, in part to thwart liquor tax evasion, and subjected violators to up to five years in prison and a $10,000 fine...
"A very, very small quadcopter, one inch in diameter can carry a one- or two-gram shaped charge. You can order them from a drone manufacturer in China. You can program the code to say: “Here are thousands of photographs of the kinds of things I want to target.” A one-gram shaped charge can punch a hole in nine millimeters of steel, so presumably you can also punch a hole in someone’s head. You can fit about three million of those in a semi-tractor-trailer. You can drive up I-95 with three trucks and have 10 million weapons attacking New York City. They don’t have to be very effective, only 5 or 10% of them have to find the target.
There will be manufacturers producing millions of these weapons that people will be able to buy just like you can buy guns now, except millions of guns don’t matter unless you have a million soldiers. You need only three guys to write the program and launch them. So you can just imagine that in many parts of the world humans will be hunted. They will be cowering underground in shelters and devising techniques so that they don’t get detected. This is the ever-present cloud of lethal autonomous weapons.
They could be here in two to three years."
— Stuart Russell, professor of computer science and engineering at the University of California BerkeleyThat's the intro to a frankly unsettling article.
...lethal autonomous weapons systems (LAWS): weapons that have the ability to independently select and engage targets... humans out of the loop — where the human releases the machine to perform a task and that’s it — no supervision, no recall, no stop function.Much more in the link.
One of the very real problems with attempting to preemptively ban LAWS is that they kind of already exist. Many countries have defensive systems with autonomous modes that can select and attack targets without human intervention — they recognize incoming fire and act to neutralize it... Meanwhile, offensive systems already exist, too: Take Israel’s Harpy and second-generation Harop, which enter an area, hunt for enemy radar, and kamikaze into it, regardless of where they are set up. The Harpy is fully autonomous...
Among the lauded new technologies is swarms — weapons moving in large formations with one controller somewhere far away on the ground clicking computer keys. Think hundreds of small drones moving as one, like a lethal flock of birds...
I worry it will breed way more terrorist activities. You can call them insurgents, you can call them terrorists, I don’t care, when you realize that you can’t ever fight the state mano-a-mano anymore, if people are pissed off, they’ll find a way to vent that frustration, and they will probably take it out on people who are defenseless.
"In the short time since I wrote that post, such pointed AI refusal has continued apace. Maine looks set to become the first US state to ban data center development outright. Form letters for refusing AI at work are circulating widely. Public polling of AI sentiment is in the gutter; it’s never been popular, and it’s especially unpopular now. A widely discussed NBC poll found that just 26% of Americans had positive feelings about AI; around half had negative feelings. Gen Z in particular loathes AI: For respondents aged 18-34, AI’s net favorability rating was minus 44."
Just as there is a blueprint for destroying democracy, there is also one for rebuilding it. “Let us now and here highly resolve to resume the country’s interrupted march along the path of real progress, of real justice, of real equality for all of our citizens, great and small,” New York governor Franklin Delano Roosevelt said to the delegates at the Democratic National Convention in 1932 as American democracy struggled to resist fascism.“Out of every crisis, every tribulation, every disaster, mankind rises with some share of greater knowledge, of higher decency, of purer purpose,” FDR said. “Today we shall have come through a period of loose thinking, descending morals, an era of selfishness, among individual men and women and among Nations…. Let us be frank in acknowledgment of the truth that many amongst us have made obeisance to Mammon, that the profits of speculation, the easy road without toil, have lured us from the old barricades. To return to higher standards we must abandon the false prophets and seek new leaders of our own choosing.”“I pledge you, I pledge myself, to a new deal for the American people,” FDR concluded. “Let us all here assembled constitute ourselves prophets of a new order of competence and of courage. This is more than a political campaign; it is a call to arms. Give me your help, not to win votes alone, but to win in this crusade to restore America to its own people.”
At 69 years old, Lady Fatou on Monday became not only the Berlin Zoo's longest-residing tenant but also maintained her title as the oldest gorilla in the world.Born somewhere in West Africa in 1957, she arrived in Europe at the port of Marseilles in 1959 amongst the luggage of a French sailor. According to the Berlin Zoo, the sailor found himself unable to pay his bill at a tavern and gave Fatou to the landlady as payment. From there, she soon ended up in the German capital.Fatou is a western lowland gorilla. In the wild they usually don't live past their 40s, and even in captivity 50 is considered advanced old age.In 1974 she gave birth to Dufte, the first gorilla born at the Berlin Zoo. Although her daughter passed away in 2001, Fatou's granddaugther M'penzi still keeps her company in Berlin. She has at least three great-great-great grandchildren as of 2026.
“My Administration stands ready to use the full Economic Might of the United States to strengthen Hungary’s Economy, as we have done for our Great Allies in the past, if Prime Minister Viktor Orbán and the Hungarian People ever need it,” Trump wrote in a post on Truth Social ahead of Sunday’s vote.“We are excited to invest in the future Prosperity that will be generated by Orbán’s continued Leadership!” said Trump, who has endorsed Orbán multiple times during the campaign.
"The story is this: Trump’s own people are ratting him out faster than a Boa constrictor with an eating disorder. Staff leaking. Pentagon leaking. State Department leaking. Every single person in that building with access to a phone and a journalist’s number is apparently queuing up to unload everything they know about the most powerful man on earth, and what they know is not flattering.This is not a leak. This is Niagara Falls wearing a suit.Carville’s referencing a New York Times story that reads like a guided tour through the West Wing’s collective contempt for the man running it. These aren’t anonymous sources with a grudge. These are the people who sit in meetings with him. The people who hand him his briefing notes and watch him ignore them. The people who stand there with a straight face while he explains how he could’ve been a general if he hadn’t had that thing with his foot.Those people. Talking. Constantly.That is not the behaviour of people who fear their boss.That is the behaviour of people who have already quietly packed their desk drawers and are just waiting for the right moment to walk...And then there’s the book.Maggie Haberman and Jonathan Swan. June. Carville calls them the pizza man. Because they’re going to deliver.Every leaked conversation. Every panicked staffer confession. Every moment where the people closest to the most powerful man on earth looked at each other across a conference table and thought Jesus Christ we are so completely fucked. All of it. Bound. Published. On shelves in June.The structural collapse of the whole operation is what Carville is pointing at underneath all the profanity. MAGA loyalty looks airtight until it doesn’t. Then it goes like a tradie’s knees on a cold morning. Fast and all at once. He’s watching the Indiana state Senate Republican primary as an early indicator. Republican voters. In Trump’s own party. Peeling away...Carville’s flat prediction: Trump will not be president a year from now. Too weak. Too exposed. Too hated by the people closest to him. And when Democrats get back in January they go straight for the corruption and they claw every dodgy dollar back...But here’s what we do know.The leaks are real. Vance sharpening his knife is real. The book is real. The polling is real. The fact that the most feared political operator in living memory is now being openly mocked by his own Pentagon is very, very real..."
"Vance brought his wife.Not a deputy secretary. Not a general. Not even a halfway competent mid-level State Department lifer who at least knows what the Strait of Hormuz is on a map. He brought Usha. His wife. To a war negotiation. The most consequential diplomatic moment since the end of the Cold War and JD thought, yeah, I’ll make a long weekend of it, bring the missus, see Pakistan...And then there’s Jared Kushner. Jared fucking Kushner. A man whose entire qualification for any of this is that he married into the right family, which, by the way, is also his business model, his foreign policy experience, and apparently now his military strategy. Jared has the energy of a guy who’s never been told no in his life because everyone around him was either paid not to or too scared to. He walked into the Middle East peace process last time and achieved absolutely nothing except making himself several hundred million dollars richer. So naturally Donald called him again...And somewhere in a Mar-a-Lago dining room, the aluminium siding salesman with the IQ of a concussed house brick is posting about tankers on Truth Social, absolutely convinced he’s winning, because no one in his orbit is allowed to tell him otherwise, and the two blokes he sent to Pakistan to save his legacy couldn’t find the Strait of Hormuz with both hands and a geopolitical GPS..."
