Where do I ask if I want to know what makes a material self adhesive?

Q: what makes a material self adhesive?

Stacey AnneI currently have a bandage on my arm that isn't sticking to me but definitely sticks to itself. What makes a material self adhesive so that it sticks to itself and not other things? What's happening on a molecular level?

adhesion

So I have a central value of 5.6 in a confidence interval of (1.9, 22.8). What looks best: $5.6_{-3.7}^{+17.2}$, $5.6_{-\phantom{0}3.7}^{+17.2}$, or $5.6_{\phantom{0}{-}3.7}^{+17.2}$?
 
user54412
Does the answer change if I mention that this value is a percent, so it will be $5.6_{-3.7}^{+17.2}\%$, etc.?

Danu
I'm sorry, I don't see the differences between your 3 proposals
 
user54412
Do you have chatjax or some such plugin? It might be breaking my tex
 
Danu
Danu
yes, I have chatjax
what does the phantom0 do?
 
user54412
$5.6_{-3.7}^{+17.2}$, $5.6_{-\phantom{0}3.7}^{+17.2}$, or $5.6_{\phantom{0}{-}3.7}^{+17.2}$

\phantom{} typesets its argument, but invisible - it takes up the right amount of space but doesn't print anything
 
user54412
good for alignment
 
user54412
and all digits should have the same size in any decent font, so I just chose 0
 
Danu
Danu
ah
I prefer to leave the alignment be
i.e. your first idea
no phantoms
as I think whitespace between the - and the number is unacceptable, and the - so far from the 5.6 looks weird too
the real issue here is to get that upper value under +10 ;D
this answer is invariant under addition of a percentage sign

@ChrisWhite I vote the first one
 
user54412
@Danu hah! I've already gotten a lot of flak from others in the field complaining my numbers are too low - they want 30 +/- 10
 
user54412
8:00 PM
well, no phantoms it is then
 
Danu
Danu
@ChrisWhite Haha, too low, too high, depends on what you're trying to show :)

Well this stinks
Anyone know of any supernova remnant images in 63 microns?
 
user54412
8:33 PM
The only student in my department who would possibly know isn't in right now

W44 and IC 443 were measured in that range, but no image exists from what I've seen
Which would be fantastic if either did because both are mentioned in my thesis a lot
Best I've found is Rho 2001 that shows total H-band flux with circles indicating where the 63 micron lines (which are O I lines) were measured
 
user54412
@KyleKanos Something like this?
 
Kyle Kanos
Kyle Kanos
Actually, scratch that: best is Burton 1990:
@ChrisWhite Ooo, that's a neat tool....I'm gonna have to fool around with that a bit

IRAS ISSA 60 micron band
 
user54412
 
user54412
Is this really the same remnant as in Burton?
 
Kyle Kanos
Kyle Kanos
It's the southern rim
 
user54412
Ah I see
 
Kyle Kanos

8:54 PM
The little bump there looks the same
But the IRAS image says it's 6h:16m while the Burton says 15m
 
user54412
Yeah I noticed
 
user54412
Well, presumably Burton 1990 wasn't using J2000? Or was it in use then?
 
user54412
And how much of a shift is there between 2000 and 1950?
 
Kyle Kanos
Kyle Kanos
IDK, but I'll have to check that out later tonight or tomorrow, as I'm heading home for the day today

All these things that I don't understand :)
