You might be thinking that getting an x-ray every day is bad for the miners, but this is a ye-olde look through machine. Yes it’s bad for the miners, but the guy looking at it is putting his face and uppee body right in the beam here. And I’m guessing he does hundreds of these a day.
Then again, old timey x-ray machines were pretty soft, so (edit) AND the miner is getting big dose of alpha and beta radiation too. And at least the technician isn’t breathing coal dust, so it’s probably a toss up who gets cancers first.
Yes. Or rather, it was flashlight photography, as opposed to “old fashioned” photography where you had to hold perfectly still for several seconds. Of course, flash powder existed before, but it was messy, dangerous, flammable and left a layer of white ash everywhere. Most people today would only recognise the pan full of magnesium flash powder from cartoons, but you can probably guess it wasn’t popular at parties or with hobbyists.
In the 1920s, flash bulbs were the awesome new thing, meaning you could take split second photos, and those could be action shots, and not staged and posed portraits. Taking a flashlight was doable quickly and easily, and of course as we all know, most random photos by random people aren’t great.
The name photograph was already used for the old thing, so “flashlight” became the obvious abbreviation.
Shawshank Redemption was a book. The Godfather was a book. Lord of the Rings, Forrest Gump, Fight Club, Goodfellas, Silence of the Lambs… That’s just from the first 25 of IMDB’S top 250.
From the top 10, only Pulp Fiction is original and not a sequel. If you go to the top 20, you can add Inception, The Matrix and Se7en. That’s 4 out of 20 (or 1 out of 10). There’s a lot more original material beyond the top 25 though, but your point that every great movie is a “ripoff” very much stands.
The big problem isn’t that the math is hard, or that’s often impossible to visualise. The problem is that a whole bunch of charlatans intentionally misinterpret what “observing” is in QM, to make money off of gullible victims.
Also, we need barriers related to quality, otherwise you get shit like Andrew Wakefield trying to sell his alternative vaccine, and in the process creating the modern antivax movement
