Contest to rename "PF Lounge" category

@Greg Bernhardt perhaps it would be a good idea to create a notification letting everyone know that this thread exists? Most people don't check the feedback and announcements forum regularly.

Lounge in Memory of 'PF Lounge'

The forum formerly known as the PF Lounge.

That's how you'd pronounce it, but you'd write it as $\aleph_0$.

The Photon futon

I hope you get one soon this has been driving me nuts

Eigenlounge

Ground state

Someone had that one?

Quarks corner
The H Bar

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)

 

[pinball1970]

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

Potato Couch

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

Potato Cauchy

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 $N=2I$.
