Although there's lots of corporate bullshit in what is written in the article linked below (namely, the stuff about self-driving cars), some insights do really standout.
"For leaders steering their organizations through this turbulent transition, what lies beyond the spreadsheet? It’s everything that won’t fit in a cell: the skills that refuse to be tallied, the open-ended problems with no reliable precedent, the intangibles—trust, taste, and the subtle dimensions of quality and experience—and the conviction to press ahead even when every metric says “wait.” Manage only what you can measure, and you surrender the most valuable ground to rivals who cultivate what can’t be counted. Amar Bose, the sound and electrical engineer who founded the Bose Corporation, proved the point: while others worshipped spec-sheet numbers, he zeroed in on how music sounded to people in real rooms—a quality no existing metric could catch—and in doing so, he rewrote the rules of the audio industry.
Directionally, the prescription is simple. Back wildcard bets with fuzzy ROI, reward teams that reframe problems and lean into the unknown, and rotate talent through roles that confront uncertainty across R&D, new markets, and complex customer, partner, and policy interactions. Carve out slack time and engineer cross-team collisions to spark serendipity and idea recombination. Treat those pockets of planned ambiguity not as liabilities, but as strategic assets."

"Modern civilisation has a number of extremely delicate and highly interconnected components whose graceful degradation is effectively impossible."
It is "much easier to break things than to build them up. The government administrations of Britain, France and Germany for example, were set up at a time in the nineteenth century when the rising middle classes demanded a properly functioning state[…]. It took perhaps a generation for professional, neutral public services to fully emerge."
"Forty years of globalised neoliberalism have broken our societies, our economies and our political systems, and we no longer have the ability to put them back together."

"Rather than using metrics as the sole truth when it comes to assessing academic performance, we should put them in perspective. We could do this by complementing quantitative metrics with qualitative information. Narratives, discussions of assumptions, and explanations can give back much-needed context to interpret metrics. Read a job candidate’s working paper instead of counting her publications in journals. Metrics can be great conversation starters, but should not replace our understanding of what (a) good research(er) is.
If we don’t change our use of metrics, research quality itself may suffer. Peter Higgs, the Nobel laureate who passed away last year, warned in an interview: “Today I wouldn’t get an academic job. It’s as simple as that. I don’t think I would be regarded as productive enough.” The pressure to produce and perform in the short term can come at the expense of scientific progress in the long term. A more critical stance towards metrics and rankings is essential if we want to enhance the quality and credibility of research."

I learned about cycling-related Eddington numbers recently.
Your Eddingon number is the largest integer n such that you have ridden at least n kilometers on at least n days (not necessarily consecutively: any days at all).
I wrote some code to find mine.
With data from 2001 to 2024, my Eddington number is 102. (I rode for many years before 2001, so my true number is somewhat (maybe just a little) higher, but records are scarce.)
So, I have ridden at least 102 kilometers on at least 102 days, and I have not ridden at least 103 kilometers on at least 103 days. In fact, I've ridden at least 103 kilometers on 101 days, so I'll need to do that just twice more to get my Eddington number up to 103. Sounds like a nice goal for 2025.
One can also use miles. An amusing thing to note is that you cannot simply convert the Eddington number in kilometers to the Eddington number in miles as you would a distance.
My Eddington number in miles is 68. 68 miles is about 109 kilometers, so my Eddington number in miles is both larger and smaller than my Eddington number in kilometers.
One can, of course, apply this to running, walking, swimming, or really any other quantifiable activity. What would be some interesting activities to apply this to?
One can also restrict the time period and look at one's Eddington number for, for example, single years. In the period 2001-2024, my (km) numbers ranged from 25 to a max of 61. The last time I was at or above 40 was 2017 (I've been in a slump since then).
Let me know if you'd like the (simple) code I wrote to calculate these numbers.
Let me know your Eddington number(s)!

Peirce's 1885 “Algebra of Logic” • Discussion 2
• https://inquiryintoinquiry.com/2024/04/03/peirces-1885-algebra-of-logic-discussion-2/Re: FB | Daniel Everett
One thing I've been trying to understand for a very long time is the changes in Peirce's writing about math and logic from 1865 to 1885. If there's anything I've learned from reading Peirce in the often dim light of intellectual history it is to be wary of progressivist assumptions — but unlike many of his other fans I apply that caution also within the body of his own work. Long story short, from 1865 to 1885 I see progress on several fronts but also bits of backsliding from his more prescient early insights. So it's a puzzle … and it will take more study to ravel out the reasons why.
Resources for reconciling Peirce's two accounts —
1. The 1870 account of logical involution
2. The 1885 account of universal quantificationPeirce's 1870 “Logic of Relatives” • Selection 12 • The Sign of Involution

❝One of the most important papers in the history of logic. “On the Algebra of Logic” was the first to introduce the term “quantifier”.❝Peirce, C.S. (1885), “On the Algebra of Logic : A Contribution to the Philosophy of Notation”, American Journal of Mathematics 7, 180–202.
• https://www.jstor.org/stable/2369451 ❞As far as quantification by any other word goes, Peirce had already introduced a more advanced and “functional” concept of quantification in his 1870 “Logic of Relatives”. The subsequent passage to Fregean styles of first order logic would turn out to be a retrograde movement toward syntacticism (a species of nominalism), as seen in the general run of what fol‑lowed in the fol‑lowing years.

• https://inquiryintoinquiry.com/2014/06/09/peirces-1870-logic-of-relatives-selection-12/The connection between logical involution and universal quantification which Peirce put to use in his 1870 Logic of Relatives will turn up again a century later with the application of category theory to computer science and both of those in turn to logic. Just one more time Peirce was that far ahead of it.

❝A Contribution to the Philosophy of Notation❞❝§1. Three Kinds Of Signs❞ (cont.)
❝For instance, take the syllogistic formula,
\[\begin{array}{clcl}\text{All}&M&\text{is}&P\\&S&\text{is}&M\\\therefore&S&\text{is}&P.\end{array}\]❝This is really a diagram of the relations of \(S,\) \(M,\) and \(P.\) The fact that the middle term occurs in the two premisses is actually exhibited, and this must be done or the notation will be of no value.
❝As for algebra, the very idea of the art is that it presents formulæ which can be manipulated, and that by observing the effects of such manipulation we find properties not to be otherwise discerned. In such manipulation, we are guided by previous discoveries which are embodied in general formulæ. These are patterns which we have the right to imitate in our procedure, and are the icons par excellence of algebra. The letters of applied algebra are usually tokens, but the \(x, y, z,\) etc. of a general formula, such as
\[ (x + y)z = xz + yz, \]
❝are blanks to be filled up with tokens, they are indices of tokens. Such a formula might, it is true, be replaced by an abstractly stated rule (say that multiplication is distributive); but no application could be made of such an abstract statement without translating it into a sensible image.❞ (3.363).

❝A Contribution to the Philosophy of Notation❞❝§1. Three Kinds Of Signs❞ (cont.)
❝With these two kinds of signs alone any proposition can be expressed; but it cannot be reasoned upon, for reasoning consists in the observation that where certain relations subsist certain others are found, and it accordingly requires the exhibition of the relations reasoned with in an icon.
❝It has long been a puzzle how it could be that, on the one hand, mathematics is purely deductive in its nature, and draws its conclusions apodictically, while on the other hand, it presents as rich and apparently unending a series of surprising discoveries as any observational science.
❝Various have been the attempts to solve the paradox by breaking down one or other of these assertions, but without success. The truth, however, appears to be that all deductive reasoning, even simple syllogism, involves an element of observation; namely, deduction consists in constructing an icon or diagram the relations of whose parts shall present a complete analogy with those of the parts of the object of reasoning, of experimenting upon this image in the imagination, and of observing the result so as to discover unnoticed and hidden relations among the parts.❞ (3.363).

@FaithfullJohn I, very successfully, used the cut and weigh method to quantify chromatographic peaks. In an attempt to increase the mass of each peak (and therefore, I reasoned, precision) I tried photocopying onto OHP sheets but quickly found the precision was worse... I figured the thickness of the OHP sheets was less consistent than paper. But this was 40 years ago...
