<p>I accept the ordering of dates is important, yes. History can be in the details, but as you say you need to comb the beach for the right stones.<p>I guess an interesting counterpoint to what I said is something like <a href="https://en.wikipedia.org/wiki/Phantom_time_conspiracy_theory" rel="nofollow">https://en.wikipedia.org/wiki/Phantom_time_conspiracy_theory</a> (and similar) where a grandiose framework tries to fit inconvenient facts into a shape that is entirely invented.</p>

<p>Yes I was not clear, it seems. Facts are necessary but not sufficient.<p>There is limited time, of course - no one can learn everything, but you can pay attention to the important facts, and the connections between them.<p>In some ideal world you would learn every fact there is, and the connections would fall out on their own, but in the real world we have to construct theories and frameworks to organise facts.</p>

<p>Agreed, it interests me how much some people emphasise knowing facts - like dates in history or dictionary definitions of words.<p>Facts alone are like pebbles on a beach, far better (IMO) to have a few stones mortared with understanding to make a building of knowledge. A fanciful metaphor but you know ...</p>

<p>I've revived a project I started around 20 years ago. It is a kind of graph query description/measurement tool for protein 3D data.<p>The query engine itself is like a DAG of 'operators', similar to a relational DB (or more like a graph one) with scanners, filters, and matchers.<p>Very fun, although not at all efficient and probably overengineered for what it does :)</p>

<p>Someone's artwork _should_ be possible to (negatively) criticise. Of course, just saying "it sucks" is not constructive or helpful.<p>You can definitely hurt someone's feeling with unconstructive criticism of thier art. However, pointing out areas to improve should not be too painful to the artist, as they can make newer, better works.<p>I suppose a difficuly can arise if people get too attached to things they make (art, code, writing, whatever) and don't see any one thing as just a step on the road to even better things.</p>

Apart from hallucinating one of the edges, this worked reasonably well to throw this into yED and give me a view on the code.<p>An alternative that occurred to me the other day is, could a PR be broken down into separate changes?

<p>Oh! I really liked the essay - the idea that French 'analysis' was seen as a dangerous modern invention and contrasted with 'synthetic' geometric understanding of the world had political implications is fascinating. There could be parallels with the present day use of computer modelling (and now AI) being seen as a risky way to organise and run societies.<p>I agree that there is a lot of vague language around the practice of mathematics as a social and philosophical construct ('analysts' vs 'synthetics') but I'm not sure how that indicates the author does not understand what truth is. My understanding of the history of mathematics and science is that these areas of knowledge were much more intertwined with philosophy and religion than they are considered to be today.<p>So Newton saw no issue with working on the calculus at the same time as being an alchemist and a non-trinitarian. Understanding the world was often a religious activity - by understanding Nature, you understood God's creation - and in Naples it seems that understanding analysis was tied to certain political and nationalist ideas.</p>
