what's 'Actinica' mean?
1) illuminating a vague or unclear problem
2) paraphernalia used at the intersection of optics and electronics
3) from the early days of photographic film when ‘actinic rays’ were the light spectrum responsible for latent images, which could then be developed into a photograph
(ok, we made up the word ‘actinica’, but that’s the idea, and the word
‘actinic’ is real – go look it up if you doubt us).
