Say I had a beam of photons with a very specific wavelength and I was able to check the position of a particle, would that position be somewhere along a very well defined sine curve? Or is that just a simplification like the nebulous clouds of atomic electron shells were dumbed down to be circular orbits that look cool as sciency logos in the 50s and 60s?

Nice! Pro-tip for pixel art though, pick a pixel size and stick to it, it adds cohesion. Use the grid of your chosen software and make the resolution very small to make sure you aren't tempted to add crisp 4k circles like the ones on that bottle. You can upscale later, but make sure to turn off any filtering when scaling or it will try and smooth out all your hard work.

It's meaningless anyway, CFF does not translate directly to a human (or animal) refresh rate or FPS. Plus we humans (CFF 50-90Hz) have enjoyed cinema at 24 FPS for over a century now, and some stop motion animation is 12 and we can still get engrossed in it.

> the pressurised can analogy kind of works if you scale it up?

It did 4 billion years ago when the debris in our Sun's accretion disk coalesced to form our planet, and again when whatever planet sized object hit us to form our Moon, but since then we've been cooling off like a pot of old coffee. Fortunately there's a lot of mass left to cool off, and it's stored in the best Thermos ever created...

It is quick but not instant which is why active noise cancellation works well on low frequencies and not too well for higher.

Low frequency sounds have a wider wavelength (and thus occur over a longer period of time). You can have a little latency between the live and generated sounds and they will still mostly overlap and cancel out. For high frequency sounds there could be several peaks and troughs in the offset gap and they're less likely to line up with the generated sound.

How does that work? I don't doubt it but it runs counter to my experience of kerbal space program orbital simulation software wherein an increase in orbital diameter requires an increase in velocity. Conversely, to decrease your altitude you must decrease your orbital velocity. 10 objects orbiting at the same velocity around a planet, in a perfectly circular orbit, will all be the exact same distance from the centre of the planet.

Actually, I've just looked up the moon's orbital velocity at 1km/s and low earth orbit as 7km/s so that's the complete opposite of what the simulation implies, which definitely requires prograde burns to increase apoapsis. I may need a layman's explanation for all this craziness.

Could a reanimated sentient hand be fully mobile with just the muscles and ligaments in and below the wrist or would it require more of the arm present? How much more?

The hand appears to have adequate blood supply and central nervous system, so these factors can be ignored for the sake of the question.

What controls for the possibility that they associate the symbols as being "dangerous" to their chance of getting a reward and therefore avoid the card with the most symbols, rather than choose the card with zero symbols?

I know it sounds like the same thing but there's a subtle yet important difference.

Plus even if they were picking the card with no symbols, that doesn't mean they understand the mathematical concept of zero, just that they understand the concept of something being absent. Practically all animals get this. They'll pick a path where there are no predators, they'll go foraging/hunting when there is no food, etc..

Not only can the doppler effect do this with sound, it works with light too. Red shift causes visible light waves to "stretch", lowering their frequency toward the red end of the spectrum. Due to the expansion of the universe the farthest and oldest light waves have undergone red shift so much that they're way past infrared into microwave territory. That's what cosmic background radiation is.

Yeah the GUI isn't exactly current-millennia, but it's unbeaten on features. There are even basic colour correction tools inbuilt, you can copy chunks of an image straight into photoshop or whatever just by selecting an area and hitting ctrl-C (saving having to drag the whole image in there), and as long as the thumbnail previews have generated it can skip through fairly large images as fast as you can spin your mouse wheel (and wrap back around if you've enabled the setting). Irfan plus Pureref for transparent imageboard overlays is an indispensable combo to any sort of visual artist / 3D modeller.

Any reason you stopped? Is there a better option? Being able to just spin through hundreds of images with the mousewheel and zoom to 100% with a single side-button click was a gamechanger. Needs a little setting tweekage after install, but after that it blows windows' default viewer out of the water.

This is why I was able to trick my friends (and myself for a while) into thinking animated jpegs were a thing. I just used to rename the file extension of a gif to .jpg.
