this retarded understanding of math is why advanced civilizations do not contact us.
we invent concepts, invent rules, pretend these work because our definitions apply because rules exist and therefore the rule is valid.
our math is 50% human brain inventions and 50% associated cope

Precision helps here. Bear with me

You CAN divide by zero. The problem is any number can satisfy the equation, so we call it undefined. There is not rule against it, strictly speaking.

you could say 0 is just an infinite-order infinitesimal, i.e. $a \varepsilon ^{\infty}$ where $a \in \mathbb{R}$ and $\varepsilon$ is the unit infinitesimal

Am I the only one who believes that citing sources is inherently cringe? If your work is good, it can stand on its own. Why should you be forced to insert another man's publishing into your body of work?

Unpopular opinion here, but I don't think a simulation is even possible. We literally have free will. You can't program free will even with a Dyson sphere... That's God level stuff.

It is, but certainly not the the extent simulationists claim it is. Also, it's just an Ifuckinlovescience meme.
>We literally have free will.
Yes, this is the most likely case.
>You can't program free will even with a Dyson sphere...
These are unrelated stuff.
>That's God level stuff.
Perhaps. But having free will not necessarily indicates that a God-level being exists, let alone created said free will. It can simply be the result of the emergent complexity of life.

There is no known mechanism that can give you anything that is remotely close to free will in the way it is usually described.

What intrinsic differences do these voltage and frequency differences make?
What different traits does a higher/lower voltage or higher/lower hertz do or any combo of these?
Is there a better combo? Or is it just different numbers that have no consequence beyond manufactured electronics?

Unironically correct, they copied the methods of RCA.

They had to do something after so many politicians kept promising that each one would do something radically more different than the last one they wasted money on. I hear now they want a "bullet train" or some stupid bullshit like that.

Like everyone said, higher voltage means higher efficiency in energy transfer. I wanted to add that because of the skin effect higher frequencies require thicker wires or are less efficient.
