@virgosxcxgroove It took my a couple tries, but Paris 1919 is pretty special

@sidefeta There’s good life advice in this video

University of California STEM professors want standardized tests back due to severe math deficiencies among students:

“We now observe preparation gaps so severe that instructors must reteach middle school mathematics”

“The current admissions metric, based primarily on GPA & essays, can no longer reliably distinguish readiness for university-level STEM majors in an era of severe grade inflation & AI assisted application essays”

@jenbegakis Woah congrats!

the academic urge to read a paper and open 23 tabs of cited articles in that paper and then not read a single one of them for 2-3 weeks, and having to nurse the open tabs and never shut down my laptop because I'll definitely get to them the next day.

man I love the brief dose of optimism Artemis gave me

@MyNameIsntEffy I think a prof would find this really relatable and your way of dealing with it mature

If students struggle with fraction arithmetic, algebra is inaccessible. If they struggle with basic number operations (including times tables), fractions are inaccessible. Math is hierarchical & gaps compound. There's no way around it. We have to get math right in primary.

@lexiewenzy_ They’re more confrontational by nature

Today's date is a PALINDROME! this is very rare. Mathematicians only notice a weird thing about the date seemingly 1,000 times a year.

This sounds like a joke, but it's not:

– 1 in 12 incoming UCSD freshmen don’t know middle school math,

– and the remedial math course was too advanced,

– so UCSD had to create a remedial remedial math course,

– and a quarter of the students placing into it had a perfect 4.0 GPA in their high school math courses.

That sounds so ridiculous, like something you’d read in The Onion, but it’s unfortunately real.

Here are some direct quotes from the UCSD report:

"Between 2020 and 2025, the number of students whose math skills fall below high school level increased nearly thirtyfold; moreover, 70% of those students fall below middle school levels, reaching roughly one in twelve members of the entering cohort."

"While Math 2 was designed in 2016 to remediate missing high school math knowledge, now most students had knowledge gaps that went back much further, to middle and even elementary school. To address the large number of underprepared students, the Mathematics Department redesigned Math 2 for Fall 2024 to focus entirely on elementary and middle school Common Core math subjects (grades 1-8), and introduced a new course, Math 3B, so as to cover missing high-school common core math subjects (Algebra I, Geometry, Algebra II or Math I, II, III; grades 9-11)."

"Few, if any, students who place into Math 2 have successfully completed an engineering degree."

"high school math grades are only very weakly linked to students’ actual math preparation."

"The correlation between the average math grade and the placement result is only around 0.25 on a scale of 0 to 1. In 2024, over 25% of the students in Math 2 had a math grade average of 4.0."

"of those who demonstrated math skills not meeting middle school levels, 94% went beyond [the minimum high school course requirement], with 42% percent completing Calculus or Precalculus."

"The pattern of high school math classes taken in many cases suggests much higher levels of math skill than the actual math skill the student often has."

"In fact, for more than two decades the Mathematics Department has found that out of all available student data, the single best predictor for math placement has been the SAT (math section) score, with the ACT score being an equally good predictor."

Kramnik understands chess at a very high level. He put up a reasonable measuring stick to determine if all the people he were accusing without evidence were cheating: prove it otb. Then he gets killed in Madrid and he says that we cannot make anything out of it. Then Daniel leads the World Rapid after 7 Rounds and ties for 1st in the World Blitz, qualifying for the group stages.
The measuring stick is met. Of course Kramnik understood this and knew that there was no credible evidence for cheating. Pointing to the case where Daniel was a queen up on a stream and was looking at what happened earlier in the game with an engine, so he could talk about it, as relevant, is very obvious bad faith and something that Kramnik entirely understood was bad faith.
It is a far more reasonable explanation to what happened, that Kramnik enjoyed the power he had to destroy people's lives. And it is easy to refute as a theory. Just come with examples of Kramnik showing compassion and regret for the damage his comments have caused. You cannot. The comments after Daniel's death are the most poignant in that context.
I don't know what Daniel would have wanted. The thing about a legal system is that the only victims are not past victims, but also future victims. The lack of regret, the serial-offence with many victims, some fragile, some less so, makes this something that has to be dealt with.

@julesgambit That series is so good

@lularobs Jobava?

@Mlambm @AlgebraFact Nice observation! If you write the sum of i*j over all i,j and do a little manipulation, it does come out to the left hand side

@bashu_thanks Bro just realize the transient nature of all experience, that it is ultimately dissatisfying, and none of it is self. Skill issue!
