This is an essay on the ease of accessing historical archives of science, not the discipline involved studying science from a historical lens. Those are two very different things that scientists routinely conflate.
- agumonkey 11y agoSimilarly I heard about an historian with a strong scientific view on history, he even coined a name for his field, unfortunately I can't remember it for my life.
- benbreen 11y agoCliometrics? At any rate, this is my favorite take on the concept of scientific history, courtesy of Isaiah Berlin: http://berlin.wolf.ox.ac.uk/published_works/cc/scihist.pdf http://berlin.wolf.ox.ac.uk/published_works/cc/scihist.pdf The parent comment makes a good point here. Although I did appreciate the nod at the end to the larger archive of historical sources that digitization has "presentized" or whatever we want to call the process discussed here. I just wish there were more dialogue between practicing scientists and historians of science - in my experience there is virtually no professional interaction.
- agumonkey 11y agoI remember a two word name, something like "fluctuative" history, but I may be wrong. I'll happily take your suggestion though it looks fascinating.

("The Tears of Donald Knuth"), which describes Knuth's reasons to study the history of a field, and also describes some of the disciplinary and institutional difficulties involved.
- agumonkey 11y agoI'm fascinated by the drift of teaching and its limited span. How in 20 years people will have forgotten about fringe or non mainstream ideas and will probably have them again thinking they're something new to dive into.
- dalke 11y agoHere's one I've been researching for the last year or so (of on-and-mostly-off research) - superimposed coding. Remember about 5-10 years when Bloom filters popped up often on HN and other tech sites? They are one type of superimposed coding. The basic idea is that a given word or descriptor gets $k$ bits, out of $N$ in a bitset. In a Bloom filter, $k$ is constant, but in the general case it can vary. In the 1940s, Calvin Mooers worked out one system of choosing $k$ based on the information content of the descriptors. He called it Zatocoding. He applied this to selecting punched cards, including punched cards with chemical data; that being the field I work in. Knuth has a bit about the approach in The Art of Computer Programming, v 3, with "false drop cookies." This technique was never mainstream, in part I think because one has to trust in random numbers, but also in practice it was applied to manual punched card searches, and it's difficult to memorize random punch codes. As computers became machines instead of people, this approach disappeared. There's a chemistry paper in about 1975 which considers it, with the phrases "old technique" and "this may appear to be a throwback", then a paper in 1976 which gives a much needed improvement for how to apply Zatocoding to hierarchical data. I think that 1976 paper is amazing. It helped me understand the problem. But it was never part of mainstream understanding. That is to say, very few modern practitioners know of the concept, it's not in any of the text books (they have a very shallow coverage of the topic), and the few papers that have referenced the 1976 article don't seem to have understood the paper, but are citing it for completeness sake. That said, it doesn't solve the problem. An alternate approach was developed in the late 1980s that's more directly related to the Bloom filter sense of using $k$ hash functions. As a result, it's detuned for the specific information in the data set, but it's able to reject new descriptors that weren't part of the training set. Based on the documentation for the method (it was never published in the scientific literature; everyone references the manual page), it comes across like a Bloom filter. However, in talking with people in the know, a specific detail was not clarified, which is that $k$ is a function of the size of the chemical feature used as the descriptor. This makes it a proper superimposed coding system. No one has looked at this information-theoretical approach in 25 years. Almost no one knows that this can even be a useful approach.
