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.
Because there isn’t much of a risk of food borne illness from bacteria inside the flesh of the fish. The big concern there, especially salmon, is the parasites. That’s why salmon is flash frozen on the boat as soon after it’s caught as possible, to kill those parasites. That flash freezing is also the only reason salmon is used in modern sushi. Properly handled, salmon is about as (if not less) dangerous than a steak with regards to bacteria. Pretty much any bacteria present will be on the surface, not inside the flesh, so those get killed w once you’ve cooked the outside. As with anything, the risk of bacteria isn’t zero, but it’s small enough that most people need not worry about cooked it until it is a dry chewy abomination.
That sounds like a lot of work. And I’m not fan of steamed fish. Salmon is like the easiest fish to pan fry.
- Heat a tablespoon (this can be a literal spoon from your table, no need for precision here) or two of olive oil to its smoke point on a pan. If it’s smoking a lot turn the heat down.
- Lightly (using course) salt salmon.
- Add to hot pan. Don’t worry if it sticks a little.
- When the salmon has changed color to right around halfway from the pan to the top of the salmon, flip it over. At this point if the pan is hot enough, even a steel pan should have released the fish. After the flip, watch the color continue to change.
- When it looks like a fish you want to eat (and the fish stops sticking) remove from the pan and plate. The edges should be a delicious crispy golden color. This is where all the best flavors get together. You don’t even need to worry about it being cooked through. I like it a little closer to raw on the inside.
The whole process takes about 5 minutes plus the time it takes to preheat the pan. I have an induction range, so the pan preheats in the time it takes me to salt the salmon.
You could probably just use some unbleached linen or cheese cloth, aka a non-decorative towel, since that is the reusable material that paper towels replaced in our modern disposable society.
Wolf314159@startrek.websiteto Science@mander.xyz•Scientists Just Made Light Speed Visible. The Images Will Break Your Brain.3·3 days agoI think our brains are pretty good at ignoring or abstracting/simplifying things we see that we don’t understand, almost too good. That’s just magic, optical illusion, or hallucination. Getting high is like chemical circuit bending. I feel staring into the void alone won’t be enough drive one mad, it’s when the void stares back and forces awareness, or knowing, that one has to worry. The non-euclidian architecture of R’leyh is just unsettling, but the stare of a multidimensional being can’t help but bend your circuits beyond their limits.
There was that one short story though about FTL travel, wherein the conscious passengers must be asleep for the journey through hyperspace (or whatever that story called it). Some people stated awake through the trip and came out the other side mad. The hyperspace itself wasn’t enough to break their brains though, it was just that an instantaneous trip from the sleepers’ perspective, became an infinitely long (in time) trip from the waking conscious perspective. At that point, what they saw didn’t really matter, it was a forced perception or awareness without the solice of “not knowing” that broke their brains.
None of this is science, just rambling nonsense.

Most of the TV we watched as kids in the 80s would have been reruns of things in syndication. Millenials born in 82 would have grown up watching reruns of Cheers for their entire childhood and likely have memories of watching even some of the later episodes live.
Wolf314159@startrek.websitetoMicroblog Memes@lemmy.world•What other great opening lines do you know?.English2·5 days agoYeah, King’s endings tend to be a little messy and narratively unsatisfying sometimes. Gunslinger is easily my favorite of the series and just about every other thing he’s written. On my last read through the story, I started with my original copy of The Gunslinger, then read through the rest of the series (reading the disconnected but related stories just before the final book), and finished with the revised edition of The Gunslinger.

Right? Most of those are all the kinds of regular maintenance things you button up BEFORE a long trip. Windshield cracks are usually either quick fixes or fixes that can be delayed or patched until you finish the trip.
Frequent enough stops to limits butt pain and blood clots isn’t such a bad idea though.

Wolf314159@startrek.websiteto Ask Lemmy@lemmy.world•More for folks from walkable environments, my question is: would you walk an hour and 15 minutes to go to say, the library?4·10 days agoAgreed. 90 minutes to go 2.3 miles sounds like a snails pace. That works out to just under 40 minutes to walk a mile. Most healthy adults should be able to jog or fast walk a mile in under 15 minutes. A 5k is about 3.1 miles and most of the slow runners finish in 30-40 minutes. I would consider 25 minutes per mile a leisurely pace. 40 minutes per mile must mean a lot of signalized intersections. I’ve found a mile or two is the perfect distance to walk home from the bar after a night out (weather dependent obviously). Maybe Google thinks they’ll be walking drunk?
Wolf314159@startrek.websiteto Showerthoughts@lemmy.world•Superhero stories have become less about saving people and more about fighting villains.71·12 days agoThere is a reason that I have fallen asleep during the extended 3rd act fight scene in every single god damn marvel movie since Mark Ruffalo became the Hulk.
They all turn into the same movie, with the same fight. And these super long fights all seem to be surprisingly light on showing any of the actual real world impacts of such violence. Nobody ever gets seriously hurt unless the plot needs more sacrifice. But even when they do, the injuries mostly happen off camera and the blood never flows or spurts, it just instantly appears as makeup. It’s really giving people a deep rooted and totally unfounded sense that violence both solves every problem (it doesn’t) and does so bloodlessly (it doesn’t). At least Batman knows he’s not a hero.
But really, the DC universe isn’t much better. Think about how shocking a little bit of blood at the beginning of the new Superman movie was, before they basically destroy metropolis (which was rather expected and mundane). And then they only show the tiny fraction of people personally saved by Superman, not the countless mangled corpses buried under rubble. This may be why the public has trouble confronting the realities of war and violence.
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.
