This is probably the best way to go. You won’t be able to beat the flexibility for the price.

Yeah, it’s about how electromagnetic energy travels through space.
- Comment on This feels wrong. I love it. 2 months ago:
If AB = i and BC = 0, then B would be in the same 2D space as C, but one of them would be “above” the other in 3D space (which doesn’t exist in this context, just as sqrt(-1) doesn’t exist in the traditional sense).
So this triangle represents a 2D object that is “standing up” on the page.

The short version is: we use some weird abstractions (i.e., ways of representing complex things) to do math and make sense of things.
The longer version:
Electromagnetic signals are how we transmit data wirelessly. Everything from radio, to wifi, to xrays, to visible light are all made up of electromagnetic signals.
Electromagnetic waves are made up of two components: the electrical part, and the magnetic part. We model them mathematically by multiplying one part (the magnetic part, I think) by the constant
i
, which is defined assqrt(-1)
. These are called “complex numbers”, which means there is a “real” part and a “complex” (or “imaginary”) part. They are often modeled as the diagram OP posted, in that they operate at “right angles” to each other, and this makes a lot of the math make sense. In reality, the way the waves propegate through the air doesn’t look like that exactly, but it’s how we do the math.It’s a bit like reading a description of a place, rather than seeing a photograph. Both can give you a mental image that approximates the real thing, but the description is more “abstract” in that the words themselves (i.e., squiggles on a page) don’t resemble the real thing.

This is pretty much the basis behind all math around electromagnetics (and probably other areas).

Oh yeah, in that case I’ll echo the other commenter that suggested Mint.
- Comment on What OS/ OSs for a core2 quad? 2 months ago:
How much RAM? My go-to would be a light Linux install, ideally Debian w/XFCE if you think it has enough oomph for that. Otherwise, there are lighter distros that will still feel nice and snappy.

I’m actually on Manjaro, but ( AUR ) probably wouldn’t have been as easy to recognize, and ( Flatpak Repository ) or ( AppImage Install ) seemed like a lot.
