I know a good number of photographers can struggle with it when they're getting into flash/strobe photography (even though may be good with f-stops generally, the moving of the flash stand appropriately takes some mental 'accounting').
In your first link the narrator says he "doesn’t understand the physics of it" but there's really no physics involved (ignoring scatter). It’s just a consequence of the math. It’s relatively easy to understand if you think of it in terms of the surface of a sphere. There is a fixed amount of light coming from a point source, and as the light travels outward you can think of it as being spread over the surface of a sphere. Since the surface area of a sphere is 4pir^2, if you double the radius the area quadruples, and therefore the light intensity at any point on the sphere drops by a factor of four.
edit: And now after rtfm I see there's a nice demo of this!
> Do religion and politics have something in common that explains this similarity? One possible explanation is that they deal with questions that have no definite answers, so there's no back pressure on people's opinions. Since no one can be proven wrong, every opinion is equally valid, and sensing this, everyone lets fly with theirs.
Well, even Republicans accepted that an insurrection was a bad thing:
> There is nothing patriotic about what is occurring on Capitol Hill. This is 3rd world style anti-American anarchy.
> There are many places that focus on, allow, or encourage political content. Hackernews is not one of them, as by express design, it deems politics as off topic:
That's all very fine and well in theory, but it's like saying the topic of the ship taking on water is not allowed to be discussed when you're on a Star Trek cruise:
Sure: a gash in the haul doesn't cover things like Kirk, Picard, Sisko, or Janeway, but it's kind of a prerequisite that nothing is happening to hull integrity before the others topics can be entertained.
> The thing that is remarkable about it is that it has this property of being information—that we made it up—but it is also machine, and it has these engineered properties. And this is where software is unlikely anything we have ever done, and we're still grappling on that that means. What does it mean to have information that functions as machine? It's got this duality: you can see it as both.
> We suffer -- tremendously -- from a bias from traditional engineering that writing code is like digging a ditch: that it is a mundane activity best left to day labor -- and certainly beneath the Gentleman Engineer. This belief is profoundly wrong because software is not like a dam or a superhighway or a power plant: in software, the blueprints _are_ the thing; the abstraction _is_ the machine.
> A big and higher definition screen provides a ton more context from the navigation's map with wider sidebars that can contain more information, while also providing more contrast and better legibility.
As someone with a 2003 Golf (with a tape deck) I find the screen on my iPhone sufficient to get me to where I want to go. ¯\_(ツ)_/¯
Related to Euro NCAP mandating physical controls for certain functions, "including indicators, hazard lights, sounding the horn, operating windscreen wipers and activating the eCall SOS function"?
> Dropping nukes was both barbaric and the more civilized option.
Also perhaps worth noting that after the first bomb the Japanese government was not planning to surrender. The second dropping moved things to a deadlock where half of the ministers—both in the small war council, and the larger full government—wanted to the surrender and the other half did not.
The Emperor had to be called in—an almost unprecedented action—to break the tie. Then, even after the Emperor had made his decision, there was a coup attempt to prevent the "surrender"† broadcast:
I do not know how anyone can think that Japan would have stopped fighting without the bombings when two bombings barely got things over the line.
The book 140 days to Hiroshima by David Dean Barrett goes over the meeting minutes / deliberations and interviews to outline the timeline, and it was not a sure thing that the surrender was going to happen: the hardliners really wanted to keep fighting, and they were ready to go to great lengths to get their way (see Kyūjō above).
The Japanese knew for a year before the bombings that they could not win the war, but they figured that by holding out—causing more causalities of Japanese, Americans, Chinese, Filipinos, etc—the US would lose their resolve and terms could be negotiated so that Japan could (e.g.) keep the land they conquered in Manchuria, etc.
† A word not actually used by the Japanese in the broadcast.
