If U=
(-2610-$\mu^2$),
then obviously x can be anything at all!

### Re: x?

So, x can be a squirrel?

Or a cup of mocha almond ice cream, which I am eating outside right now.

It is better than x!!

But back to math:

With U+2610 standing for a box  symbol sa=tanding for a d'Alembertian, it's a free field (no particle interactions) Klein-Gordon equation, and the solution x, a.k.a. $\phi$, is a plane wave.

Correct! U+2610 is unicode for Box, and this means it is the K-G equation.

And the Winning prize is a full zero spin with the Higgs boson! (that probably hides in a Klein (Gordon?) bottle)

$(\Box+\Delta-\nabla^2+\mu^2)\psi=0$

### Re: x?

Sounds like a monologue interior to me.
More undefined symbols, meshuggah

BTW $\Delta == \nabla^2$

or have those finicity physicists discovered  a new symbol?

Correct! Exactement!
The real problem is that Collector had not defined ..

Alan says squirrel, I say witch.

Haha - it is fine giving credit where due and if you plugged that equation from the original post into Google - the Unicode for box is the top hit.

Back in the 1980s, I had to load hexadecimal codes in manually for character set for my first computer. A good intro to primitive computing.

These days, I am loading up plates with nutritious meals for someone... Hopefully can be released with others by a professional rehabber when ready.

Note the mask - is this a coincidence or did my new totem animal find me?

Riding on the front of the broomstick!  Let's see what happens when you type witch into Wolfram Alpha, one moment...

Interesting - a good listing, including this word frequency histogram

See also some interesting word facts and AI-powered stream of consciousness here: Wolfram Alpha query "witch"

And so, here is a brainteaser for all of you:

(Wolf(ram) + Python + witch) x^pandemic = ?

Back to research now!

LaTeX math commands u possibly don't know, that are essential to know

\xrightwitchonbroom*{f_{1}+\dots+f_{n}} gives

Very nice! The authors of the top book shown here really missed an opportunity - should have added an Appendix with such information! : )

MatLab also lacks a sense of humor, but I have found that Wolfram and even the Wolfram Language certainly have one.
Testing some calculations with new friends a few weeks ago:

/wolfie Mass of Arnold Schwarzenegger in Planck Masses

2:32 PM
/wolfie Mass of Arnold Schwarzenegger / 21 micrograms

2:32
2:32

So, you see, the precision of terms and numerics matters! (And impacts the calculation time too.)
