Im not sure if its *his* LaTeX code, the entirety of his second post looks like its cut and paste from the Wiki article.

Yes, the [8] was a bit of a give-away. By "his" I meant whatever code he wants to render.My standard reply to explicit declarations of SMOP is "Best hit the books. It'll be simple."

the risks outweigh the benefits, better tuning/turning the universe inside out

Does it need a cubic meter of equipment, consuming 15kW power?

So many questions, and no answer on wikipedia

Maybe https://www.quicklatex.com/ ? Paste in your LaTeX code, click button, copy and paste the link they provide. You get a rendered image, they get a backlink.LaTeX may not be the best choice of markup here

Im not sure how informed the user is about the subject, its a bit 'hey this is some thing that mentions oscillators, so SMOP, where do I get?'

Consider the one-dimensional quantum harmonic oscillator. Quantum mechanics tells us that the total (kinetic and potential) energy of the oscillator, E, has a set of discrete values,

{\displaystyle E=(n+1/2)\hbar \omega ,\ n=0,1,2,3,\dots ~,}E=(n+1/2)\hbar \omega ,\ n=0,1,2,3,\dots ~,

where ω is the angular frequency of the oscillator.

However, in a classical harmonic oscillator such as a lead ball attached to the end of a spring, we do not perceive any discreteness. Instead, the energy of such a macroscopic system appears to vary over a continuum of values. We can verify that our idea of macroscopic systems fall within the correspondence limit. The energy of the classical harmonic oscillator with amplitude A, is

{\displaystyle E={\frac {m\omega ^{2}A^{2}}{2}}.}E={\frac {m\omega ^{2}A^{2}}{2}}.

Thus, the quantum number has the value

{\displaystyle n={\frac {E}{\hbar \cdot \omega }}-{\frac {1}{2}}={\frac {m\omega A^{2}}{2\hbar }}-{\frac {1}{2}}}n={\frac {E}{\hbar \cdot \omega }}-{\frac {1}{2}}={\frac {m\omega A^{2}}{2\hbar }}-{\frac {1}{2}}

If we apply typical "human-scale" values m = 1kg, ω = 1 rad/s, and A = 1 m, then n ≈ 4.74×1033. This is a very large number, so the system is indeed in the correspondence limit.

It is simple to see why we perceive a continuum of energy in this limit. With ω = 1 rad/s, the difference between each energy level is ħω ≈ 1.05 × 10−34J, well below what we normally resolve for macroscopic systems. One then describes this system through an emergent classical limit.

This name sounded great even for a DIY project of making a synth or a song even.

If anyone already got it share it! (or let us know where you bought it!)

I have the shakes too much these days to even consider soldering smd, through-hole is bad enough.
