This all seems as exotic or esoteric to us now as these invisible electromagnetic waves were to Heinrich Hertz, who reportedly regarded them as mere scientific curiosities with no practical applications.

Unable to foresee radio, television, telephones, remote controls, microwave ovens, Wifi, Bluetooth... you get the point, that "thing with no practical applications" is now a staple of daily life, and all around us. We have fully tamed Electromagnetism.

Now with things like Quantum Computing and Bose-Einstein Condensates, we are starting to tame a new esoteric scientific curiosity - the probability wave function, the Uncertainty Principle.

Heinrich Hertz did not foresee things like satellite television and Spotify while looking for a spark flying across two metal tips from his dark room in the 1880s, but surely we have a better grasp of what potential benefits the newest technologies have in store for humanity?
Or are we for the most part still in the Hertz-like naive fiddling process?

Either way, there is going to be some incredible magic inside that quantum box!

For example, Humphrey Bogart as Indiana Jones in Raiders Of The Lost Ark. Or say Gregory Peck in Saving Private Ryan. Or how about James Dean as Luke Skywalker!

In the color lines of a spectrograph and what seems to be an area with a certain color, zooming in shows that this color is delicately split in half by a black vertical hairline, on one side it's the emission of photons of color by a hydrogen atom with a spin up electron, on the other it seems to be the same color but it's a spin down electron.

Whenever I hear that gap mentioned, 1/137 is invoked, but I'm not sure precisely what that means, and I'm visualizing that the color of the spectral emission can be divided or deconstructed into a total of 137 vertical lines, and the one in the middle is black.

Maybe it represents 1/137 of a photon's wavelength at a certain color?

For example, places like HistoryPorn have some bizarre pictures of weird inventions or WWII experimental weapons.

How come I'm only just now coming across them? Why didn't we see them five or ten years ago, even in specialized forums and subreddits?

Places like ArtPorn or TraditionalArt are a trickier proposition. Here my lack of knowledge is vast, but I've really loved the history of painting for over two decades now, and have recently kept coming across a lot of 18th-to-20th century paintings and painters I've never heard of before; some of these are excellent, I should have known about them... I think. But like I say, there's more that I don't know than what I do.
If they are real and not recent AI creations, where are the original and who is digitizing and/or publishing so many of them all of a sudden in the past year?
