Eigenlounge

So the new lounge will look exactly like the old lounge, but a different size?

I suggest to modify your first suggestion to "The Quark's" as we all(?) are Trekkies, although I assume that most of us have their difficulties with the Rules of Acquisition.

We could add an "s". Thus we have more possibilities: old = new, 0=BH, -1=weird news and so on ...

 

[pinball1970]

Are you sure? Guess many won't find out again.

My partner pointed out I have stolen something from Deep space nine, I don't watch it so it was done in good faith

But you nailed it. It's basically the lounge on DS9 run by an alien named Quark.

I loved the old star trek - I just could not accept anything after that (Jame T Kirk one)

Zeta function room

I don't know what half this stuff means

 

[pinball1970]

La Place?

Sounds a bit pretentious, like a bar in Manchester- the expensive part where the footballers go

Infinity Lounge? - Someone must have had that?

Sounds a little Douglas Adams

Considering the fetish physicist have to frames and coordinates, we should prefer "Des Cartes".

I don't think I am getting enough of these jokes, If it is not a joke then I am not getting enough of the physics

Not sure I understood it right but here's what I meant: In physics, everything is about frames, frames and transformations between frames. Frames are coordinate systems. The most used coordinate system are Cartesian coordinates. The word Cartesian is because of René Descartes. And "Des Cartes" is French for "Maps". Too indirect?

That depends on who operates

Perhaps we can keep the word "Lounge" in the title but can we make it a little more creative?

Sorry, found an error in that statement:

It does not matter if we all commute.

Even if we all commute, it still can have different sizes, and depends on where you enter it, as well as who operates it.

Im a stamp collector, I need to read my Linear albegra book all the way through I think.

How about the Neutron lounge? No charge for entry?

Okay, a bit of linear algebra: Linear operators M have a set of eigenvectors v_i such that $Mv_i = \lambda_i v_i$ for some constant (the eigenvalue) $\lambda_i$. As an example, an operator "mirror the z-direction" in 3D space would have the x- and y-direction as eigenvectors with eigenvalue 1 and the z-direction as eigenvector with eigenvalue -1. "Mirror across the plane x=z" would have the y-axis and a vector (1,0,1) as eigenvector with eigenvalue 1 and the vector (1,0,-1) as eigenvector with eigenvalue -1.
In general different operators have different eigenvectors - if you apply an operator on an eigenvector of a different operator you get something, but in general not a multiple of this eigenvector. There is an exception: If two operators commute, then you can find a set of eigenvectors for both operators together. For operators M,N "commute" means $MNv=NMv$ for all v. For people, "commute" means something else...

However, not necessarily eigenvalues. E.g. $M=I$ and $N=2I$.

I vote now also explicitly for Eigenlounge

Reasons:

• It fits, as one of the most frequented forums is QM.
• It fits, as the "eigenworld" is THE essential part of physics: from classical resonances to QFT
• "eigen" is probably the most used word on PF (common language out of consideration)
• It fulfills the requirement that "Lounge" is still a part of it.
• Edit: And "eigen" means "belongs to", "is property of", "is invariant of self". Sounds perfect.
• It's fancy.
• It's short enough to make no problems fitting on the site.
• EL is a short cut we don't use otherwise.
• And last but not least: I can pronounce it correctly!

The forum at the end of universe, because it shows up at the bottom of the webpage and has a bit of pop culture. It's where we go to relax, not dive right back into physics.

Does not roll off the tongue although I like the Douglas Adams connection.

I agree with @Tom.G and @phinds. PF Lounge is I think the best and is what it is.
It reminds me of great looking women that have found their perfect type hair style ... and they insist on getting a new one! (for a change! ...). When they suddenly (with no warning) they finally do get it ... the disaster happens! and e.g. that's when marital and relationship problems begin ! ... (so to speak)

The category will stay how it is, but maybe we can be creative in its name. I refuse to believe I lazily came up with the best name possible

But you did!

However, if you really insist, I think "PF Lounge Cafè" is perhaps ideal.
The more complicated the more lame it gets, IMO.

 

[Stavros Kiri]

If it's the PF part you really want to replace then perhaps "Non-crackpot Science Lounge" ...
[That reminds (a small part of) PF rules as a handy echo, so that people don't foget in the lounge one of the main PF directives (and get really carried away) ...]

How about "Zero Kelvin Lounge"...cause its a chill relaxed place ?

 

[pinball1970]

was this not settled?

 

[Navin]

was this not settled?

I dunno...but the threads still open.

It might be "unsettleing" for some that this hasnt been settled !.. hah hah...yea...that was lame wordplay on my part.

A name is just a name. PF is not in status quo ...

So chill that the threads won't even move!? ...
That would indeed bring "PF status quo"! ...
