Physics, polymers and composites, high-rate mechanics, and what I'll euphemistically call "software carpentry" and not "hideous hacks". Occasional uninspired photography.
Good: delightful shade under the trees in Vigelandsparken.
Bad: it turns out I'm allergic to their pollen and about to turn into a wheezing, sneezing mess.
Good again: P3 filters vanquish pollen utterly.
And that's why I'm wearing my mask outdoors on a sunny day.
Last night's auroras, from sunny 52° north in a streetlit housing estate on a slightly cloudy night. Someone should probably check on our satellites.
To the eye these were just faint god-beams with no real colour. Images have been vigorously de-noised with Lightroom's denoisinator.
Oh look Starlink. I hope they don't crash. That would be terrible.
(I know, the odds of Musk having put in a responsible de-orbit on failure system are slender, they'll probably find a way to turn into a million needles and kickstart the Kessler cascade)
And my confusion about emission lines in fluorescent panels was because at work we mostly used halophosphates for our fluorescent tubes, until we replaced them with LEDs. So none of the lines in their spectra are from phosphors: they're just mercury emission.
