Inside a combustion chamber, temperature fluctuations can cause sound waves that also disrupt the flow, in turn. This is called a thermoacoustic instability. In this video, researchers explore this process by watching how flames move down a tube. The flame fronts begin in an even curve that flattens out and then develops waves like those on a vibrating pool. Those waves grow bigger and bigger until the flame goes completely turbulent. Visually, it’s mesmerizing. Mathematically, it’s a lovely example of parametric resonance, where the flame’s instability is fed by system’s natural harmonics. (Video and image credit: J. Delfin et al.; research credit: J. Delfin et al. 1, 2)

It's important to remember we're going about 30km/s along with the Earth in order to stay in orbit (or else we would already be falling into the Sun).
To hit the Sun, you have to go all the way to zero, or 30 km/s ΔV. To escape you need to increase to 30√2 km/s -- or about 13km/s extra. Less than half as much!

There are definitely many real-world issues and problems where we could benefit from significantly more quantitative (and mathematical) analysis and thinking than we do currently. But, at the same time, there are certain dimensions of our modern society where we overcorrected for this, and allowed quantitative reasoning to dominate at the expense of other important modes of thought, or to be deployed in a highly imbalanced fashion.
As anyone who has encountered a word problem in their high school math classes knows, the first step in quantitative reasoning is to assign numerically precise metrics as proxies for one's goals, parameters, and variables. Most of our wants and needs are quite qualitative in nature: happiness, comfort, security, companionship, and the like. But these are too fuzzy to be optimized and analyzed by the mathematics of quantitative reasoning. Which, to oversimplify things, leaves us with basically two options: either use more qualitative modes of thinking, such as "gut feelings", emotional responses, or drawing on past experiences of similar situations, accepting any cognitive biases that result from doing so; or to create quantitative proxies for these goals, and then optimize those proxies in a more dispassionate (and hopefully more objective) fashion. (1/5)
The ongoing process of "enshittification" in corporations and other institutions can also be viewed through this lens. Companies (and other complex organizations) have gained access to increasingly sophisticated metrics to measure their user activity, and now have the technology to optimize those metrics for their own benefit (in the near-term, at least). Initially, this sort of optimization can add value for both the provider and consumer of the service; but the majority of their customer base are not playing the optimization "game", and many would have initially signed up for an experience that was more qualitative and less optimized, and containing more of the intangible benefits that even the most advanced metrics fail to capture.
So, are metrics good or bad for individuals and communities? It is a very complex question. In some areas, we are under-using metrics; in others, we are over-using them; and in yet other areas, they are being deployed in too imbalanced a fashion to be beneficial in the long term. Perhaps what we need is more of a discussion of meta-goals and meta-metrics: not just how to pursue a goal or to optimize a metric, but to try to analyze (both qualitatively and quantitatively) how similar or distinct these two objectives actually are, and to locate a stable balance between them that can be broadly accepted within the community in question. (5/5)
@KStahl Very interesting discussion! Thanks for sharing.
I don't think companies act against their interest when sacrificing consumer satisfaction, though. I think that these companies have realized they can offer the least satisfying product possible that maximizes their gains by reducing satisfaction that is cost-inducing (e.g., improving product quality) and monetizing satisfaction that is not (e.g,. choosing your airplane seat). This strategy appears to be economically viable, unfortunately, and there's a whole system in play to protect it and show it as optimal (mostly by erasing losses of "irrational" i.e., qualitatively defined goods like comfort).
In principle, an efficient and liquid market does provide precisely this dimension reduction (and is one of the key distinctions between an economic system and a physical system). If one possesses a multidimensional vector of various goods and services, then by trading in such a market, one can exchange this vector for other vectors. If one makes the (sometimes justifiable) assumption that the efficient frontier of such exchanges forms a differentiable hypersurface around one's current state vector, then the normal to that hypersurface naturally determines the "price" of each good, and one can then measure (marginal) increase or decrease in one's effective wealth (modulo this efficient market) by the one-dimensional metric of taking the dot product with this state vector.
But for goods that are illiquid or only available in inefficient markets in which arbitrage opportunities exist, then this dimension reduction is no longer available, and price becomes a much more complicated notion (for instance, there can be non-trivial spreads between bid and ask prices). In particular, problems can arise when some goods are priced in a liquid fashion, but others (e.g., environmental goods such as clean air and water) are not; then optimizing value using market prices can lead to one sacrificing illiquid goods for liquid ones in a non-beneficial fashion.
@SylviaFysica - on a vaguely related note, I'm enjoying some ideas in Will Storr's book "Status Games", which posits that after satisfying some basic needs we're primarily motivatived by the search for status, which he loosely divides into:
• Dominance games: Status is imposed by force or fear.
• Virtue games: Status is awarded for moral behaviour and adherence to group norms.
• Success/competence games: Status is given for skill, talent, or achievement.
I think he'd claim the quest for money is, once basic needs are satisfied, largely a proxy for status - so, maybe some sort of mixture of a success game (money as a way of demonstrating success) and dominance game (money as a means to achieving dominance).
As with all pop psychology/sociology, there's lots of criticize about this, but I think a lot of economics could use a bit more attention to the underlying psychological/sociological aspects. More here:

I recently learned about the fallacy of the average pilot, which somehow eluded my awareness until then!
Collapsing complex multidimensional systems into single dimensional metrics is almost certainly always a bad idea. The representational volume of defined ranges over the space will occupy an exponentially smaller volume of the total space as the dimensionality of the space grows linearly. It follows that the inverse is true: a single metric can capture only an exponentially vanishing proportion of the total variance of the system as the dimensionality grows linearly.

If you can't be bothered to use a CW (Content Warning) for #USpol, or for #Trump, #MAGA, #fascists, then please take the briefest second and use a hashtag. I mean, it is literally just one extra character.
At a minimum, please use #uspol as a hashtag for US stuff.
Please use real names for the people you have issues with- Dolt45, 45/47, Orange Julius, Tangerine Toddler, etc... nobody is going to be able to filter those out. Some people are either going to be materially harmed by this person, their administration, and/or their followers- or they have been. Or they don't live in the US and really don't want to see this right now.
So, use names people can filter against, and please consider that some people have had enough USian trauma for today.

“AI slop” doesn’t cover it. It’s more like “I stepped in a pile of hot AI poop again.” Literally, if you look closer at the illustration.
I was searching for “fire heat radiation.” When a slightly promising article started going over the same basics of conduction, convection, and radiation for the third time, I got suspicious and looked closer at the illustrations. “Hot poop” indeed.

@ArnimRanthoron Um. I think you are misinterpreting the image, both misreading what is shown and also missing important details.
* The "big man" is a depiction of Donald Trump. His obesity is exaggerated.
* The size reflects power and status (of being president elect), and not that it's a statue, I think.
* Trump is depicted with tiny hands.
* Mickey is _genuflecting_ not dead.
* The figures offering moneybags are paying tribute.
* Two of them are recognisably Elon Musk and Jeff Bezos. The other _may_ be Tim Cook.
* There is another figure not offering tribute, the one with lipstick; it may be J D Vance or Matt Gaetz. (I am not American and don't pay that much attention to its political figures.)
* Mickey is not the only figure in colour; Bezos' jacket is blue.
