This gives me God Emperor of Dune vibes.

The diffraction effects from a pinhole camera are not what make them work.

I didn’t say this, you did. You’re chasing your own tail.

The ratio of the size of the image to the distance from the pinhole is the same as the ratio of the size of the sun to the distance to the sun.

A pinhole camera has no lens. The effect here is like a pinhole camera, but a pinhole camera is nothing at all like a lens. Pinholes diffract light. Lens refract light.

EDIT: Of course you can’t resolve an image through diffraction. That’s not how pinholes cameras work. Diffraction negatively impacts image resolution, but it absolutely happens when light passes through them. But, although lens do use refraction to resolve an image, that same process also has unintended negative effects on image resolution (spherical aberration, chromatic aberration, etc.). I didn’t bring up any of that because it was ultimately a distraction from the important part: narrow gaps diffract light, lens refract light, and pinhole cameras do not work like lens.

Dude I’m not arguing that it’s correct or not, I’m saying that this is the way many people used to (and how some still do) use the language.

Yeah, that’s why my comment was basically words and phrases have shifting connotations as time passes and contexts change.

Fake and real photograph used to have a very different meaning indeed.

This is a “real” photo of Denise Richards and Paul Walker:

Primates make tools to help eating ants, among other things. It’s a bit of an unusual snack, but people eat ants too. We are anteaters? How much of your diet needs to be ants before you’re considered an anteater?

Not to be confused with disco snails.

There’s a lot of people in this thread proudly sharing how they stereotype and have preconceptions about people that they don’t actually know. And them their justification is that everyone should be a two dimensional single issue character archetype with literally no conflict or contradictions. Have you people even met any adults, especially professionals and academics, that aren’t your parents or your teachers?

You’re comparing archeology today with the field’s rather sorted past rooted in imperialism. They point out this issue in several, if not all, of the movies. This issue also comes up multiple times in the latest game. Nobody is denying that Dr. Jones is an outlier and a rogue amongst his peers. That conflict is like that core of the character’s motivation throughout. He’s a hero of western imperialism fighting fascist imperialism. We tend to view ALL imperialism in a negative light today (as it should be), but that certainly wasn’t the case when we were fighting literal Nazis.

Focusing at a point behind the image is exactly what we’ve always done for every other magic eye poster because it only requires relaxing your eyes (staring off into the distance) for the image to pop into focus. Cross eyed viewing is damn near impossible on any screen at less than an arm’s length away without significant eye strain or external devices (like the stereoscopic viewers that photogrammetrists would use to view these kinds of images without inducing a migraine) and since the dot is on top holding a finger up as a guide ends up obstructing the entire view unless your arms are growing out of your forehead. The wall eyed view has none of these issues.

I appreciate the post and your effort. But, the images themselves are frustrating and have killed my initial reaction, which was to share them further. Because I’m nearly the only person I know that wouldn’t loose interest in the explanation for “correct viewing” half way through. If they were wall eyed stereoscopic images, I could just say “Magic Eye”, they’d remember Mallrats, see the schooner, and go “Ooh neat.”

We killed our trajectory because the cold war ended and we were no longer engaged in an arms race involving rockets. Once capitalism figures out how to exploit space for infinite growth we’ll get back on track assuming we don’t great filter ourselves first.

Are you 100% certain it’s not a cell phone tower?

These are often just appear as a sheet metal pillar from the outside. If you see a small windowless concrete hut surrounded by a fence somewhere on the property, the church could be leasing to a telecom and hiding the antennas inside their oversized idol. Icing on the cake is that this is often a method the telecoms use to hide their operations from local municipalities so that they can avoid taxes until caught.

Was that supposed to be coherent or relevant? Are you lost?

If you’re going to be snarky about units, at least get the significant digits correct. The infographic gives 100°F as the temperature. If I had to guess I’d say that wherever that number came from, it’s precision is much less than a whole °F, but for simplicity let’s just say that the precision is a whole number, no decimal places in the precision. At that precision 37.5°C and 38°C are both also 100°F. There are 9/5 °F for every °C after all. If you’d said 37.7°C I wouldn’t have even commented. But that was one decimal place too far (and being too lazy to find the ° symbol or type out degrees).

You’re all probably saying, “Who cares? Why do you care? Aren’t you just being any even more annoying pedant?”

I do. I don’t know. Probably.

But, if you’re going to be a smartass, you better at least try to be smart about it.

Because vector graphics take up much less space. That’s the joke.

Now I’m going to put the joke out of it’s misery.

Most of the illustrations, formula, tables etc. in a math book could be vector graphics, most of them were in 90% of the upper level math text books I’ve ever had, usually in only 2 colors. Many math formulas can be represented and formatted directly using only Tex or LaTex. Mostly physics and math involving more than two dimensions would have more raster images, even color. But it’s not like the publishers are going to be handing out PDFs with original vector graphics embedded. That would make high quality knockoffs trivial.
