Thank you for the improvement of the figure! Kakila (talk) 23:13, 24 November 2012 (UTC)

No problem! ^_^ Maschen (talk) 16:52, 25 November 2012 (UTC)

Levi-Civita symbol[edit]

Hi Maschen, please note that the original coordinate system of my drawing (as well as the system you show) is RIGHT-handed, not left-handed, as you state in your description. Furthermore, you place the cubus with its edges on the axes, so that its inner corner is located at (0|0|0), while in my drawing its most inner corner is located at (1|1|1). This is a difference! And please don't count on "the reader should guess the true meaning" - such pictures must be quite "fool-safe", as they might be the most suggestive information for somebody studying the respective subject for the 1st time. So please correct the decription, and shift the cubus so that the indices match, ok? With regards, --Qniemiec (talk) 23:36, 3 January 2013 (UTC)

I may have mixed up the description with another drawing (File:LeviCivitaTensor.jpg). I'll fix soon, thanks for feedback. Maschen (talk) 15:47, 4 January 2013 (UTC)
Hi Maschen, have taken a look to your latest SVG version, and now it is as it should be, including the description ;-)). Thanks. --Qniemiec (talk) 17:18, 4 January 2013 (UTC)
No worries, sorry to mess things up before... Maschen (talk) 19:12, 4 January 2013 (UTC)

RE: File:Radioactive decay modes.svg[edit]

That looks good to me. If it was a more dramatic change I would have recommended creating a whole new commons file but I think its fine. --MarsRover (talk) 18:33, 4 January 2013 (UTC)

Ok, thanks again. Maschen (talk) 19:12, 4 January 2013 (UTC)

about http://en.wikipedia.org/wiki/File:Vector_components_bases_projection.svg[edit]

Hi Maschen, While reading about the Bra-Ket notation and trying to understand it, I was looking at the illustration you have done, http://en.wikipedia.org/wiki/File:Vector_components_bases_projection.svg. I may not get it well, but could it be possible that the green vector on the left, basic vector notation example, should be named simply "A", and not "|A〉" like the one with Dirac notation on the right? It is surely not a significant problem, but it would make it clearer for non-expert like myself. Thanks

Preceding comment by 24.201.114.50 (talk).

ACH another of my very annoying copy-paste typos. You're right it should just be bold A, not a ket. It is fixed now (you may have to refresh your browser, if not then the servers will synchronize and update the image in a few days).
The image is just showing the analogy between the boldface and Dirac notations (at the most basic level, there's quite a lot to Dirac notation, but essentially it is a notation for abstract vectors in state spaces).
Thanks for posting here. Best, Maschen (talk) 16:09, 22 December 2013 (UTC)
