As far as I know, the "single particle" referred to here is not a "classical particle" like a ball. It's a "quantum object" that, depending on how you look at it, behaves like a wave or an object. Definitely spooky!


Cool tool! I often play odd time signatures, e.g. I'm trying to program the drums for Rondo ala turk by Dave Brubeck (repeating 2-2-2-3 pattern). Can you tell me how I can do that?


Sorry, this drum machine cannot do 9/8 time.


Man, this was hard to read. Irrespective of what actually happened, this found-guilty-by-popular-opinion mentality is a corrosive evil, and it's been worsened by social media. Hard to believe that this community just ignored "innocent until proven guilty" so casually.

I used to naively believe that people are generally good. I still believe that but with a major qualifier. There are some truly toxic people out there who are seriously mentally fucked up and don't hesitate to screw with others' lives. They seem normal and nice at first, but if you look closely enough, you see the trail they have left behind.


I think one of the reasons communities like Scala's are susceptible to this pattern is that they have some characteristics of a movement and compete for attention with other movements, so there's a knee-jerk response to protect the movement and all the effort put into it from being associated with bad stuff. Most signatories to this letter were likely erring on the side of protecting their community, at the risk of an individuals' fate.

(I'm also discussing this neutral to the actual issue, which I don't know much about and haven't made my mind up on.)


Jon didn’t actually deny the claims though. The accusation is that someone had sex with him and then regretted it and tried to end the relationship but he creeped on her. He said he didn’t think his actions were creepy but that doesn’t mean they weren’t and it certainly doesn’t mean they didn’t make the accusers uncomfortable. Losing his job over this is a bit much but after reading all the evidence I would not invite him to conferences either. He clearly has awful social skills and habitually makes people uncomfortable. The lack of anyone standing up for him points in that direction as well although there are many other possible explanations so I won’t hold that against him.


Jon comes off pretty skeezy in the entire situation. I'm shocked to see such full throated defense of his actions here.

I think his posts are written to confuse people into thinking he won some settlement with his accusers, which is not the case, he reached an agreement with folks who amplified his accusers claims. He did not refute the claims by the women at all.


While my fear of crowds may not be as strong as yours, I see your point of view. In most situations, it doesn't take a lot for a crowd to become a mob.


To me, his solo stuff from the 80s and mid 90s sounds so much more musical and awesome than his work with Black Sabbath. The Ultimate Sin (1986) and No Rest for the Wicked (1988) are just incredible. I must have listened to at least one of his songs every day between 1985-1991.

Goodbye, Ozzy. Your music was a big part of my high school and college life.


I'm not a techie, so perhaps someone can help me understand this: AFAIK, no theoretical computer scientist predicted emergence in AI models. Doesn't that suggest that the field of theoretical computer science (or theoretical AI, if you will) is suspect? It's like Lord Kelvin saying that heavier-than-air flying machines are impossible a decade before the Wright brothers' first flight.


> Doesn't that suggest that the field of theoretical computer science (or theoretical AI, if you will) is suspect?

Consider the story of Charles Darwin, who knew evolution existed, but who was so afraid of public criticism that he delayed publishing his findings so long that he nearly lost his priority to Wallace.

For contrast, consider the story of Alfred Wegener, who aggressively promoted his idea of (what was later called) plate tectonics, but who was roundly criticized for his radical idea. By the time plate tectonics was tested and proven, Wegener was long gone.

These examples suggest that, in science, it's not the claims you make, it's the claims you prove with evidence.


I’m not even clear on the AI def of “emergent behavior”. The AI crowd mixes in terms and concepts from biology to describe things that are dramatically more simple. For example, using “neuron” to really mean a formula calculation or function. Neurons are a lot more than that and not even understood completely to begin with however developers use the term as if they have neurons implemented in software.

Maybe it’s a variation of the “assume a frictionless spherical horse” problem but it’s very confusing.



Has emergent behavior ever been predicted prior to it being observed in other theoretical fields?


I believe it's been predicted in traffic planning and highway design and tested in via simulation and in field experiments. Use of self driving cars to modify traffic behaviors and decrease traffic jams is a field of study these days.


emergent behavior is common in all large systems.

it doesn't seem that surprising to me.


That is not the question.


Maybe I can make this more clear for you:

Yes, the answer is yes. lol

see: physics, biology, economics, sociology

more granularly: cellular automata, phase transitions, trophic cascades, scale-free networks, swarm intelligence, the list goes on...

all of this was modeled theoretically before it was observed.


About the Robotaxi: I really, really wanted to impressed by what they will demo. However, I thought it was more marketing, with the product being "just two years away" as always. The demo was in a controlled environment so I doubt its real-life capability. I guess I will believe it when I see it on roads. Disappointed.


He was one of the few industrialists who gave capitalism a good name. He was never one to do ostentatious displays of wealth or buy islands. He used his vast wealth and influence in the best possible way.

RIP.


They gauge he would've been the richest person in the world at many points, if not for his generous philanthropy


While the internet is flooded with thousands of posts about his demise, this statement you made is what I 100% agree.


The text i supposed to be banal, so that ChatGPT can make it better. It's like the before picture in an exercise course.


It's not, is it? It's meant to be the draft it created from the notes.


Extremely interesting! We have still so much to learn.

This seems to be an example of Extremeistan as described by Taleb. Can this specific research be extended to any other domains, e.g. finance? Most financial software uses known worst case scenarios while doing retirement planning, such as a 30% drop in equities. What if the worst case is a lot worse than 30%? Asking for experts to weigh in.


What they've done here is a specific model of a specific physical phenomenon, that predicts higher extremes than the previous models predicted (and better agrees with certain observations that contradicted the previous models). Specifically, they are modeling certain aspects of how waves that oscillate both along and across the main direction of motion behave.

You can't apply this research itself to finance, because it's about the movement of water, not money. You might be able to take inspiration from some of the math, or take heed that even well established models can turn out to be wrong in significant ways.


> Most financial software uses known worst case scenarios while doing retirement planning, such as a 30% drop in equities.

... yes, and of course in retrospect of 2008, COVID, land war in Europe, "totally not a war in the Middle East" ... who knows what's the right "worst case" scenario.

But. But. There are clear difference between business as usual and blatant charlatanism masquerading as BAU. (See the snippet below, highlighting the bad deals between 2006 and 2008.[1])

And rating agencies just issued AAA or whatever. This of course points to problems with the industry not with science. (See also the linked reddit thread.[2])

D. Fallen Angels

Next we examine structured finance securities that suffered the most severe downgrades. From 1983 to 2008, 11% of the tranches were eventually downgraded 8 or more notches (fallen angels). Table 7 decomposes these fallen angel tranches by their original credit rating. Tranches rated below Ba3 cannot fall more than 8 notches by definition (the lowest rating, C, is precisely 8 notches below Ba3). Surprisingly, we find that most fallen angels were originally rated AAA (19%). Tranches originally rated Baa2 or A2 make up the next largest portions of fallen angels at 12% and 10%, respectively. Clearly, some of this is supply driven (every CDO has a AAA tranche, but not every CDO has a Aa1 tranche). Table 7 also shows that nearly all of the fallen angel tranches (86%) were issued between 2006 and 2008, underlining the poor quality of recent deals.
