fading margins

This morning I am watching the lecture I linked to on Tuesday!

At 6:53:

Here is an example of how the Hubble telescope image of the Omega nebula, or Messier 17, was created, by adding colours -- which seem to have been chosen quite arbitrarily -- and adjusting composition.

The slide is figure 13 (on page 10) from an Introduction to Image Processing (PDF) on the ESA Hubble website; I'm baffled at the idea that the colours were chosen "arbitrarily" given that the same PDF contains (starting on page 8) §1.4 Assigning colours to different filter exposures. It's not a super clear explanation -- I think the WonderDome explainer is distinctly more readable -- but the explanation does exist and is there.

Obviously I immediately had to stop and look all of this up.

(Rest of the talk was interesting! But that point in particular about modern illustration as I say made me go HOLD ON A SEC--)

One of the things I found yesterday, while getting distracted from transcription by regretting not having taken History and Philosophy of Science (or, more accurately, not having shown up to the lectures to just listen), was some tantalising notes on the existence of a four-lecture series entitled Visual Culture in Science and Medicine:

Science today is supremely visual – in its experiments, observations and communication, images have become integral to the scientific enterprise. These four lectures examine the role of images in anatomy, natural history and astronomy between the 15th and the 18th centuries. Rather than assessing images against a yardstick of increasing empiricism or an onward march towards accurate observation, these lectures draw attention to the myriad, ingenious ways in which images were deployed to create scientific objects, aid scientific arguments and simulate instrumental observations. Naturalistic styles of depictions are often mistaken for evidence of first-hand observation, but in this period, they were deployed as a visual rhetoric of persuasion rather than proof of an observed object. By examining the production and uses of imagery in this period, these lectures will offer ways to understand more generally what was entailed in scientific visualisation in early modern Europe.

I've managed to track down a one-hour video (that I've obviously not consumed yet, because audiovisual processing augh). Infuriatingly Kusukawa's book on the topic only covers the sixteenth century, not the full timespan of the lectures, and also it's fifty quid for the PDF. I have located a sample of the thing, consisting of the front matter and the first fifteen pages of the introduction (it cuts off IN MID SENTENCE).

Now daydreaming idly about comparative study of this + Tufte, which I also haven't got around to reading...

(Last week's also now exists and is no longer a placeholder!)

Reading. Pain, Abdul-Ghaaliq Lalkhen. I want to be very, very clear: unless you are specifically researching attitudes and beliefs in pain clinics in early 2020s England, or similar, do not read this book. There are bad history and no references, appalling opinions on patients (), quite possibly the worst hyphenation choice I have ever seen, stunning omissions and misrepresentations of pain science, and It's Weird That It Happened Twice soup metaphors. Fuller review (or at least annotated bibliography entry) to follow, maybe.

Some further progress on Florencia Clifford's Feeding Orchids to the Slugs ("Tales from a Zen kitchen"), which I acquired from Oxfam in a moment of weakness primarily for EYB purposes at a point when it was extremely discounted. It is primarily a somewhat disjointed memoir for which I am not the target audience, but hey, Books To Go Back In The Charity Shop Pile but that I wouldn't actually hate reading were exactly the goal, so that's a victory. Mostly. I'm a little over halfway through it, sticking book darts on pages that contain recipes for easier reference when I go back through on the actual indexing pass.

I absolutely needed something that was not going to make me furious and furthermore that was not going to be demanding, and there's a new one in the series, so I have now reread several Scalzi: Old Man's War and The Ghost Brigades completed, The Lost Colony in progress.

I've also had a very quick flick through the mentions of Descartes in Joanna Bourke's The Story of Pain, which is my next Pain Book. She does better than everyone else I've read, but I still think she's misinterpreting Treatise on Man. (Why do I have strongly-held opinions on Descartes now. CAN I NOT.)

Cooking. SOUP.

smitten kitchen's braised chickpeas with zucchini and pesto, two batches thereof, because I had promised A burrata to go with and then (1) the supermarket was out of it and (2) the opened part-pack of feta wound up doing two days quite comfortably, so the second batch was required For Burrata Purposes.

I have also established that the pistachio croissant strata works very well in one of the loaf tins if you scale it down to 50% quantities because there were only 3 discount croissants at the supermarket (... because you had to wait and watch the person who got there JUST ahead of you taking Most Of Them...), which also conveniently used up the dregs of the cream that I had in the fridge.

Eating. Tagine out the freezer (thank you past Alex). Relatively fresh dried apple. A very plain lunch at Teras in Seydikemer, which was apparently the magic my digestive system needed to settle itself down! And I am very much enjoying my dark chocolate raspberry stars. :)

Previously: uk.bookshop.org were selling a Tor ebook with DRM applied, which I only noticed after I had bought it, because all? Tor ebooks? are DRM-free? at the request of the publisher? Like, Hive applies DRM to them, but given that bookshop.org lets you filter for DRM-free, this... was surprising.

My initial support request for (1) an explanation and (2) any chance of a refund, realise this is totally on me though, ... got me an almost-immediate refund, which I was not expecting, and a very entry-level explanation of What DRM Is, which I sort of was. So I wrote back saying thank you very much, and also, Tor went famously DRM-free in about 2012, and they're definitely supplying this specific ebook to other retailers without DRM applied.

There was A Pause.

A day or two later I received a response from someone with "Senior" in their signature, thanking me for my patience and saying they were Investigating.

A few days after that I noticed that the ebook in question was now marked DRM-free: hurrah! ... but when I bought it, and clicked on the "yes please download my DRM-free ebook" button, nothing happened.

I did not write back in because I have been. preoccupied.

But a few days after that I tried again and this time the download did work! So hurrah for bookshop.org needing me to do much less assertive escalation than I'd been expecting, and also for noticing that something was still broken and Fixing It without me needing to get around to e-mailing in about it.

... the quick part of this note was going to be: I know there were Questions on my first post about Hey They're Doing Ebooks Now, about how you actually filter for DRM-free. As far as I can tell this isn't actually possible from the ebooks landing page, which seems A Pity, BUT when you search for something (which can absolutely be as vague as "science fiction"), the FORMAT dropdown lets you filter for DRM-free ebooks only. Obviously this is Not Ideal, in that one might actually like to browse All DRM-Free Ebooks, but it does exist as an option, where as far as I can tell it doesn't, at all, on e.g. Kobo. Hopefully this knowledge is helpful! And certainly The Above Saga has caused me to think sufficiently positively of them that I'm likely to default to them for my ebooks in future.
