@ManishEarth any chance the user (I think this one: physics.stackexchange.com/users/24353/ahmedmolvi) behind the recent spam could be eliminated?

ManishEarth

done

Q: adding a spam flag statement on the community collumn on the right

Would it not make life easier for moderators if a banner were displayed on the right requesting users to flag spam, making clear that six flags would get rid of the offending entry?

feature-request

user54412

also, wasn't the previous registrant part of the spam? physics.stackexchange.com/users/24352/molanafakir

user54412

or am i misremembering

ManishEarth

08:19

yeah

At the time I'd not destroyed those two because it's easier to catch them when they aren't making new accounts

But yeah, time to destroy both

user54412

well, time to get a nap in before the chat session...

ManishEarth

@ChrisWhite oh there's a chat session? yay!

ManishEarth

Hello chatters

Hennes

Shhht. Do not distrub the silence . ;)

David Zaslavsky

Hey everyone

Turns out I'm actually on the road today, so I won't be able to fully participate

But I'm here as long as cell coverage holds out

... really nothing?

twistor59

Bit on the quiet side today. The usual riff-raff haven't turned up :-)

David Zaslavsky

I guess not

twistor59

16:15

OK chit chat it is then: Are you permanent academic staff or post doc David?

David Zaslavsky

Grad student actually

so neither

twistor59

Oh well, wasn't far off! How much longer've you got to go?

David Zaslavsky

Probably a year

I'm planning to start writing my thesis this summer

twistor59

I just remember how painfully long it seemed to take to write up. Agonizing over each page (and mine was only 120-130 pages or so - no data, just maths)

David Zaslavsky

I can only imagine

At least I like writing, to some extent

twistor59

16:23

That's a serious bonus! Do you fancy continuing the academic stuff, or might you sell out and go to industry/rock music or whatever?

David Zaslavsky

I'd like to continue in academia but I'm not sure the jobs will be available

twistor59

Ah well I guess things haven't changed much - they were few and far between when I finished in '84.

David Zaslavsky

... oh, my phone's battery is running low (already!) gotta run, sorry

twistor59

Cheerio..

David Zaslavsky

We'll continue this later :-)

Q: A double-sided lever and multiple forces

Assume a double-sided lever where the left arm has a length of a and the right arm has a length of b + c. Please refer to this link for a picture. a, b, c and F are known and F1, F2 and F3 are not. F is a force acting upon the lever as a whole. How do I find the F1, F2 and F3 forces? I was thin...

homework forces

For example ^^^

ok thanks

sorry but the page where i was trying to post is called physics meta. I suppose that the problem.

thank you for your help

user54412

@BreitnerOcampoGomez yeah, meta.<subject>.stackexchange.com is for discussions about the managment/implementation of the website <subject>.stackexchange.com

@BreitnerOcampoGomez any reason why your Toeplitz operator question belongs here and not math.se?

Q: An application of Toeplitz operators

I want to find an application of the Toeplitz operators. All I need is a known problem (not an open problem) which solution use the theory of Toeplitz operators. I don't need all the details but I need the reason why the Toeplitz operator becomes important in the solution.
