Q: Tag merging: "Star: and "Stars"

Christian BuenoIt seems that star and stars are two separate tags and there's not good reason for them to be so, especially when the latter is only used 4 times. I suggest to merge both into star.

Q: The "Calender" tag ?!

Dimension10Why in the world do we have a tag for calenders? Only 4 questions use it, and it's a very non-physics tag. How much moment of force to knock down this caleunder? Tropical year is 27s/year off from Gregorian year?

@ManishEarth: Ready to answer something..?? ;-)
Starts from there... :P
 
Why will it just change the direction?
Depends on friction
 
@ManishEarth And, it's frictionless... My "scene" is totally concentrated on how forces act... So, Am I right?
 
@CrazyBuddy If there's no friction the piston won't change the perpendicular component of v
 
@ManishEarth It doesn't add up any magnitude... But, it does change direction...
 
It does add magnitude
$v_x$ stays unchanged
$v_y$ changes from 0 to some nonzero value
 
12:09 PM
@ManishEarth Exactly... that's my case... So, the change in direction depends on both vectors.. That's where I got confused ;-)
 
As in?
 
@ManishEarth V_x and V_y... The resultant... o_O
???
And @ManishEarth: what is the SE chat bot?
 
@CrazyBuddy Huh?
Hmm
Here, I'll draw a picture
The piston provides an impulse $J=\Delta mv_y$
 
12:27 PM
@ManishEarth Done... Hey.... I got clarified by the first phrase you said... ;-)
I thought you were drawing the SE bot :)
So, I was keenly looking... :P
 
@CrazyBuddy It's a JS script that you can run that makes you into a bot
watch

!!/help
!!/help get
 
So...???
 
!!/google foobar
huh, not working
 
@ManishEarth: I don't really understand.... You know I'm quite disinclined with programming nowadays :P
 
@CrazyBuddy You run it when you're logged in, and as long as the browser window is open people can send bot commands and the script will make you post the corresp output
 
12:34 PM
bots make me post... Really??? o_O
 
yeah
it's simple
Basically the script runs on your browser
So it can send stuff
 
ahh... cool :D

I find one of John's answer interesting (like everytime) ;-)

A: Why wet is dark?

John RennieWhen you look at a surface like sand, bricks, etc, the light you are seeing is reflected by diffuse reflection. With a flat surface like a mirror, light falling on the surface is reflected back at the same angle it hit the surface (specular reflection) and you see a mirror image of the light fal...

@ManishEarth: So, I thought of creating my blog this week.... :)
Essentially, we can write anything there.... Right?

Q: Criteria for the popular-science tag.

Dimension10At Getting rid of the popular science tag, Shog9's (rather reasonable, in my opinion) was accepted. So here, I think we should standardise the definition of popular-science. If the answers are technical, but the question was phrased in a pop-sci way, should it be tagged as popular science...

Q: Including Mathematica code in a response

joshphysicsWhat is the best way to visually include Mathematica code in a response? I am almost done writing one right now, and I'd like to include a small amount of code which shows a computation demonstrating a result I claim in the response.

Popped in to say that this is an awesomely named chat room. Kudos!
