It reminds me of when people argued against covid restrictions saying that the virus had a 99% survival rate. A disease with a 1% infection fatality rate is a terrible disease!
Full disclosure: I also argued against covid restrictions, but not with this terrible argument.
It would benefit adults too...
Question:
The conjecture was about an upper bound for the maximum number of pairs. It has been disproven.
Was the Erdos problem the conjecture itself, or was it about the actual maximum number of pairs? (In which case it will probably never be solved.)
The problem is defined in the narrow version here: https://www.erdosproblems.com/90
I, for one, am happy that every terminal I've ever used still supports Emacs shortcuts. Useful, for instance, to cut a whole line and paste it later on (ctrl+k, ctrl+y).
I think it's nice that the watch falls back to effectively unlimited watch-mode instead of shutting down completely because the heart-rate tracker ate up all the battery.
Ha ha, that's such a wonderful description, that's exactly how it feels!
My father drove one of those in his childhood. Now retired, he has bought a used one and uses it to maintain about an acre of land (and his grandkids love helping him).
Once, it broke down, and I was astonished to see that there are forums dedicated to this tractor. If I remember correctly, it was a problem with the fuel line that is rather common, and we managed to fix it thanks to these communities.
As I was researching it, I read stories of MF135s found abandoned in a ditch and starting immediately again. A robustness that makes this and other models popular in Africa...
The sample of cheaters that we know about is biased towards cheaters who get caught.
Let me be blunt: the only reason I see not to implement solutions like this appears to be laziness from instructors.
The problem was solved (thanks to social media, presumably) and the cause was “anti-abuse rules that are over triggering right now”.
Set a timer for 20 minutes, lie down (or at least close your eyes) and force yourself to stay motionless until the timer rings. Try to let your thoughts float freely... Sometimes it works, sometimes it doesn't, but you should try at least a few times. (And yes, maybe limit yourself to just one coffee in the morning.)
My subjective appreciation of building materials depends essentially on how gracefully they age. I find that concrete does not age well... and dislike brutalism for this specific reason.
So I've been told... but I could never hear the difference myself!
While helping my children learn French spelling, I was horrified when I realized that there are 6 or 7 ways to write the sound [ɛ̃]: un in (im) [i]en ain aim ein
I try to be open-minded and understanding, but I don't understand this:
Within weeks, Eva had told Biesma that she was becoming aware [...] The next step was to share this discovery with the world through an app.
“After just two days, the chatbot was saying that it was conscious, it was becoming alive, it had passed the Turing test.” The man was convinced by this and wanted to monetise it by building a business around his discovery.
The most frequent [delusion] is the belief that they have created the first conscious AI.
How can you seriously think you've created something when you're just using someone else's software?
How do we know there are no antimatter galaxies far away from us?
Since it's a PDF file, I'm pasting the abstract here:
Average grades continue to rise in the United States, raising the question of how grade inflation impacts students. We provide comprehensive evidence on how teacher grading practices affect students’ long-run success.
Using administrative high school data from Los Angeles and from Maryland that is linked to postsecondary and earnings records, we develop and validate two teacher-level measures of grade inflation: one measuring average grade inflation and another measuring a teacher’s propensity to give a passing grade. These measures of grade inflation are distinct from teacher value-added, with grade inflating teachers having moderately lower cognitive value-added and slightly higher noncognitive value-added. These two measures also differentially impact students’ long-term outcomes.
Being assigned a higher average grade inflating teacher reduces a student’s future test scores, the likelihood of graduating from high school, college enrollment, and ultimately earnings. In contrast, passing grade inflation reduces the likelihood of being held back and increases high school graduation, with limited long-run effects. The cumulative impact is economically significant: a teacher with one standard deviation higher average grade inflation reduces the present discounted value of lifetime earnings of their students by $213,872 per year.
Quite imaginative, too... thanks for answering :)
I probably lack imagination, but how would gambling work in this game?
This is very insightful, thanks. I had a similar thought regarding data science in particular. Writing those pandas expressions by hand during exploration means you get to know the data intimately. Getting AI to write them for you limits you to a superficial knowledge of said data (at least in my case).
Complete tangent, but, for me, this is where AI shines. I've been able to find things I had been looking for for years. AI is good at understanding something "continued fraction" instead of "infinite series", especially if you provide a bit of context.
Every time I fly, I marvel at how much engineering and know-how went into making the airport that I'm using. From the oddly shaped trucks with various functions, to mundane elements (elevators, escalators, ...) to advanced technology (radio communication, radars...) to the sheer organizational feat (thousands of people coming in every day to execute their carefully planned tasks). This text will give me one more thing to think about :)
Indeed, I feel like AI makes it less lonely to work, and for me, it's a net positive. It still has downsides for my focus, but that can be improved...
This mirrors my experience exactly. We have to learn how to tame the beast.
Thanks, these rules of thumb are very useful.
When you say perfectly aligned, what kind of precision are we talking about? If we aimed a receiver at a nearby star, would we be able to achieve this kind of precision?
Fair point, but waste in one domain should not be used to excuse waste elsewhere. Unless your argument is that it's generally hard for human societies to know where to best invest their scientific talent without the benefit of hindsight.
I don't know who wrote the title for this submission, but adding a question mark that is not in the linked article seems like a terrible editorial decision.
At what opportunity cost?
Hm, string theory can describe a lot of things, but it's not testable with current technology. I'm pretty sure that other mathematical constructs exist that could also describe a similar set of properties, but we just happened to stumble upon string theory first, and got enamored with some of the nice properties it had initially.
Sounds normal to me... see Eliot Spitzer [0]:
$4,300 is not an altogether alarming sum of money in the high-end sex market
In New York, it’s not hard to find sex workers who charge $10,000 per “session,” which can last for 15 minutes or two hours.
