Ahh, it’s no big deal. I know it sounds magical, but there’s probably some humdrum explanation…you’re probably just popping in and out of different universe in the multiverse whenever you observe a particle, or something mundane like that.

And the high powered laser itself is behaving strangely.

If we setup to disprove that light is particles, no luck, it’s a particle. If we setup to disprove that light is a wave, no luck, it’s a wave.

I understand there’s some reasonable quantum explanations, but many of those have some very weird implications. Last time I tried to wrap my head around it, we were still working on disproving whichever of the quantum theories we can disprove. That’ll be nice because it’ll likely rule out a lot of silly theories, while leaving an equally silly but probably true, theory standing.

Okay imma need an explanation for the middle bottom and bottom right panels, what are they?

Also love the idea that magic is just science we haven’t explained yet. Most of us would be burned s as witches in the past based on our current knowledge

Solely based on knowledge, yes. In practice most of us wouldn’t be able to create a half working lamp from raw materials.

This is also why at see inventions emerge almost at the same moment from people who don’t share knowledge.

A lot of invention is material science.

Even if I know enough to make a modern computer from raw materials, I’m not going to find the necessary industry to refine those raw materials correctly in the 1400s.

Middle bottom is the demon core, an extremely radioactive orb:

I have a habit of calling things ‘technological magic’ because that’s what it is in my mind. The fact that the universal laws and logic exist in such a way to allow things like computers or the huge complexity of living things and AI matrixies is nothing short of miraculous when you think about it.

It’s something I’ve been proud to recognise and when electroBOOM did his piece on it, I was glowing with pride.

But the basic FBR there creates pulsating DC, for steady DC, you need capacitors, to trim the peak voltage and fill in the dips.

Though, if you have three phase, with each phase on a FBR, and combine the DC output, it’s pretty steady on the output because of how three phase works (no capacitors needed), and I think that’s pretty cool…

Seriously though, three phase AC is really interesting in how it functions.

Weird how magic and mystery stops being magic when scientists have words for it.

One day we’ll discover the afterlife, but we’ll just call them “Post-Human Conciousness Wells” or something, and insist it totally isn’t the same thing as that ancient superstition.

Cmon, you wanna tell me the world is purely material when our math literally uses imaginary numbers to make sense of things?

Imaginary numbers are merely a poorly named mathematical construct used to reconcile the empirically observable phenomena of nature (e.g., summations of waves). They’re the means by which we achieve mathematical closure under exponentiation. You could call them whatever the F you want, so long as they could be used to represent vectors in the complex plane.

What reason do you have to believe in anything outside of material nature?

Up to the introduction of quantum mechanics imaginary numbers where only ever a theoretical tool and any calculation in electromagnetism, mechanics or even relativity can be done without them.

Also, any measurement you can make will always result in real numbers because there is no logical interpretation for imaginary measurements (a speed of 2+i m/s doesnt really make sense)

There’s a really good science fiction novel by Robert Sheckley called Immortality, Inc. where scientists in the future have discovered that there is an afterlife, but the only way to ensure you get there is a medical procedure and you can only do that if you can afford it. That’s just the beginning, there’s a huge amount of worldbuilding, but that’s the main theme of the book.

actual theoretical physicist here: “imaginary numbers” are just poorly named, there’s nothing imaginary about them. You might as well use 2D geometric algebra to do the exact same job (treating real numbers as scalars and imaginary numbers as pseudoscalars)

Math is a tool of the mind to describe our world, imaginary numbers is only a extension of that tool to allow us to go beyond what mathematical logic prevents us to do, while still getting in the end a real number. Math, despite being powerful, is a flawed tool, so getting around its flaws by creating things like imaginary numbers isn’t absurd and doesn’t make the result any less real at the end.

On the other hand, I don’t think calling everything we don’t understand “magic” or the new trending words “supernatural” and “a miracle” and give god or anything else (like karma) credit for it would be more clever. Back then, we didn’t understood the concept of thunder and interpreted it as god’s wrath. Now, we understand it’s a transmission of electricity from the negatively charged clouds to the neutral ground through ionized particles in the air. I don’t think that scientists now, despite referring to the same phenomena, are talking about the same thing as we did a long time ago.

So no, no scientist will discover the afterlife “but we’ll just call them “Post-Human Conciousness Wells” or something, and insist it totally isn’t the same thing as that ancient superstition.” as it won’t be.

Stating mathematics is a tool doesn’t answer if mathematics are real or not. But I would say, from my humble experience, that mathematics is both unreal and perfectly tangible. Mathematics is totally a real thing as it obeys strict rule in logic that are true in our real world, axioms, on which everything else is based so that it can’t be used to state things as being true out of the blue, without any justification before using those axioms, which you can translate into our real world. But math also has its limits and has been used to demonstrate that it itself is incomplete, undecidable and inconsistant (mathematically, of course, it’s not our common definition here). Meaning, as mathematics are imperfect, it can’t describe our world perfectly and therefore isn’t real.

There is an excellent video from Veritasium on the subject of the limits of math: https://piped.video/HeQX2HjkcNo

And it’s great. Though, as a religious person, thinking this way is no more than shooting yourself in the foot, which is quite sad because religion has only two choice: either cultivating the ignorance but going against science, which is wrong, or cultivating knowledge but overtime, disappearing as a religion. Either way, nowadays it’s doomed.

Friend of mine (who is dead now ironically enough, and damn, I miss him), wrote a story about this. Where the dead show up on some random planet in the Andromeda Galaxy, in their prime, one that’s infinitely large and does the minecraft thing where it generates as you go, and contains the means to do pretty much anything except for leave… with them just showing up in the Capital City of the planet if they die again, which cannot be done of natural causes here.

The dead initially think it’s Heaven, but then they notice “Heaven” is being powered by a Dyson Sphere, eventually they connect enough of the dots to realize that their world is a simulation.

The protagonist is the grandchild of one of the deceased who wound up here after testing experimental teleportation technology, turns out the simulation brought him there to inform him why teleportation technology shouldn’t be invented.

Eventually the grandchild goes back to Earth, agreeing to keep this a secret, for fear that if people knew about this it would create “Dyson Sphere cults” and would encourage people to commit mass suicide, just “dying to get there”

It’s not random, you can’t simulate the universe with a 1d10… you need ∞d10 to get the right probability distribution for each throw. Luckily it adds up to a 1d10 when you throw an actual 1d10, just don’t ask why.
