Wow, this is wild. billionths of a second?!
"Millionths", abbreviated "mths of a second" here for... reasons... Known to the entire world, including American STEM people, as a microsecond.

I'm reminded of Grace Hopper's famous nanoseconds lecture: https://youtu.be/gYqF6-h9Cvg?t=78
1 ns * c = 1 ft, to put in perspective: 7 μs * c is 1.3 miles. (Protip: just type "7 μs * c in miles" into Google)

Anything to avoid using the proper units, you wouldn't want the Americans audience to be enlightened wouldn't you.

#45Every time I read about one of the national labs doing this research, I wonder how much longer we will head about these. I feel fairly positive that DOGE's layoffs and budget cuts mean this output will fade away in time.
I worry about this, but these capabilities are hard to replace. This kind of research hasn’t historically been something you can outsource to private companies. Or—at least—it hasn’t been until now. Even if this administration wants to open that door, the infrastructure investment required for the accelerators alone is staggering: easily in the multiple billions.

The national labs are absolutely getting budget cuts.
For sure. But depending on what Congress does, think defense budgets could grow, which would mean more money for defense-positioned Labs like Los Alamos.

It’s for bombs, it’s untouchable.

The first line of the articles says "seven-millionths of a second", which would be 1/7μs or 0,14μs. They also mention that the camera shot 16 frames in that period, so that would be once every 0,00875μs or once every 8,75ns Youtubers are a couple of magnitudes away from that, AFAIK
I would say you described "one seven millionth" of a second (1/7,000,000 s) "Seven millionths" would be 7/1,000,000 s (7μs). They take 20 to 40 images in that period using 7 cameras, so any given camera might be as low as 1.4μs per frame.
