accessing File:Mplwp universe scale evolution.svg to change language to French

Looking at usage File:Mplwp_universe_scale_evolution.svg, the file at each country is in English (but the application of English isn't true at least of the originating sources i.e. Einstein was German) - the subject is globally relevant and of universal importance, so should be accessable to other languages in their own language for interpretation, but there isn't any edit function that allows a translation to be made to the file.

thanks,

Luckily the image comes with its source code. So in order to create a translation, you save the code, edit the labels to any language, then execute the script, and upload the translated file with a new name, e.g. Mplwp universe scale evolution (language).svg. Alternatively one can carefully edit the svg source with a text editor to put the text in a <switch><g systemLanguage="..."> Tag, then upload it as a multilingual version. See Commons:Translation_possible/Learn_more#Multiple_translations_within_one_SVG_file. --Geek3 (talk) 15:34, 5 March 2020 (UTC)

vectorfieldplot

Dear Geek3, I'ld like to use drawings af field lines made with VectorFieldPlot in a textbook on general physics for engineers. The book will be published this or next year by Hanser Verlag. Are there any requirements or restrictions to do so? Kind regards WEfitzroy — Preceding unsigned comment added by WEfitzroy (talk • contribs) 13:36, 6 March 2020 (UTC)

If you create your own custom images with VectorFieldPlot, those will have no restrictions. You can apply your own license. If you like, you can mention VectorFieldPlot as a reference. You can also come back to me if you have questions about specific field arrangements. --Geek3 (talk) 14:26, 6 March 2020 (UTC)

Why Gallery of Wigner distribution functions in Fock states page subsection Bosonic fock states?

As title, wondering why you added Gallery of Wigner distribution functions to this section such as File:Wignerfunction fock 0.png. Wigner functions are not referred to anywhere else in this article. Thanks! — Preceding unsigned comment added by Xunger08 (talk • contribs) 03:09, 17 March 2020 (UTC)

The Wigner function is one of the most illustrative ways to display Fock states. Those distributions are heavily used in physics and should also be available on Wikipedia. But you are right, maybe they should be referenced in the article, or there might even be a better suited article? --Geek3 (talk) 11:12, 17 March 2020 (UTC)

Hydrogen atom

I use your image Hydrogen_eigenstate_n4_l3_m1.png in all my books. I am now publishing my 4th book and will also be adding the image Hydrogen_eigenstate_n6_l3_m1.png. Lacking a functioning memory, working alone, and being self taught I now need to learn a little of the chemistry of the hydrogen atom.

I am aware that there is only one electron in a hydrogen atom and your images show electrons in multiple locations. Am I to assume each eigenstate is part of a separate atom, or does the image show a single atom in lots of different locations in the same atom.

Kind regards — Preceding unsigned comment added by Arlington row (talk • contribs) 08:30, 2 May 2020 (UTC)

Those are single-electron orbitals of one atom. Although, there are multiple, disconnected regions in the orbital, it is still only one electron which is spread through all those regions. This is the case for each of the orbitals that I plotted. In fact, the electron's wavefunction can take an almost arbitrary shape with as many separate regions as desired. What I plotted are only the special cases that are stationary over time, i.e. they don't change their shape immediately (those are eigenfunctions of the energy operator). --Geek3 (talk) 10:23, 2 May 2020 (UTC)

VectorFieldPlot.py for Python 3

Since Python 2.x reached end of life as of January 1, 2020 and pip is no longer supported with version 2, I would like to ask if it would be possible to publish a VectorFieldPlot.py version for Python 3. I tried to convert your script using 2to3, but the script still does not work with Python 3. Thanks. MikeRun

Good idea. I will convert it soon then. --Geek3 (talk) 14:39, 4 May 2020 (UTC)

I've seen the image of a magnetic field of an infinite wire and image the magnetic field of a horseshoe magnet created with your script. Just to be sure: I'd like to create the vectorfieldplot as in Current Carrying Wire in a Magnetic field(right side). Is this possible with your script?

Sure you can combine these two fields. All you have to do is to list both field elements in the field. What I see in your graphic is a wire in a rather constant field, so you could also use a [[User:Geek3/VectorFieldPlot#homogeneous_{Fx,_Fy}|homogeneous field]] or two cylinder magnets. An example field would be field = Field([ ['homogeneous', {'Fx':0, 'Fy':1}], ['wire', {'x':0, 'y':0, 'I':1}] ]). I will also have the Python 3 version finished within the next few days. --Geek3 (talk) 14:52, 5 May 2020 (UTC)

Thank you for beeing so helpful!!! --MikeRun (talk) 15:45, 5 May 2020 (UTC)

I just uploaded a python3 version of the script. Enjoy! --Geek3 (talk) 20:19, 6 May 2020 (UTC)

Great! I will try tomorrow... --217.149.173.228 16:13, 7 May 2020 (UTC)

Wow what a great script!!!! My first work: . Thank you so much!!! --MikeRun (talk) 17:52, 8 May 2020 (UTC)

Sorry to bother you again. I tried to run the code of with the current version 3.0 and I got an "NameError: name 'ig' is not defined" error. Any idea? --MikeRun (talk) 21:23, 8 May 2020 (UTC)

added "ig = sc.integrate" and "op = sc.optimize" to the "# some helper functions" section to the VectorFieldPlot script. now the code works. hope you don't mind that I changed your script. --MikeRun (talk) 06:27, 10 May 2020 (UTC)

I have changed the packet names to "integrate", "interpolate", "optimize", "special" so that the usage is more easily understood and they are not accidentally overwritten by other variables. I think using the long names is no big disadvantage. --Geek3 (talk) 21:30, 10 May 2020 (UTC)

Agreed! --217.149.173.228 13:01, 11 May 2020 (UTC)

Hey, I refined the field shape for File:Electric-peak-field2.svg, hope you don't mind. --Geek3 (talk) 19:04, 11 May 2020 (UTC)

Generating Xenon Atom for Science Documentary Series

Hey Geek3,

Hope all is well. I really like your atomic orbital renderings, and I was wondering if you would be available to animate a 3D Xenon-136 atom with all of the orbitals superimposed for a science documentary televisions series? Shoot me an email at soren.shade@vice.com if you are interested!

Thank you so much! Soren

Hi Soren, thanks for your interest. Unfortunately, a Xenon atom with its many electrons is much harder to compute than the orbitals that I modeled here. All those, despite their complexity, are still the simplest case of only one single electron in a hydrogen atom. In order to compute a Xenon atom, much more involved software is needed. Also, there is not just a single density of having the electron in certain places, but also the probability of having two at the same time, or any number up to 54 electrons (actually, since Xenon is a nobel gas, there will be 8 electrons that play a major role and are "visible" from outside. Also, Xenon136 looks exactly the same as Xenon132, only the nuclei are different). There are specialized physicists at universities, who can for sure compute the precise structure of a Xenon atom, but I don't have the means to do that. So, I'm afraid I won't be able to help you. But I would recommend to search for quantum chemistry departments of universities and ask people there, I'm sure there are scientists who have modeled any type of atom and can create images from that. --Geek3 (talk) 13:10, 27 September 2020 (UTC)

One-cycle sine curve

Hey Geek3, in relation to the w: Taijitu character ☯, I wish you to make a one-cycle sine curve, say, sine1.svg, from -1*pi to +1*pi, in addition to -2*pi to 2*pi of your sine.svg. Sincerely yours KYPark (talk) 09:39, 28 November 2020 (UTC)

Dear KYPark, check out File:Sine one period.svg. Also, note that the Taijitu character consists of circles, not sine curves. Cheers --Geek3 (talk) 10:12, 29 November 2020 (UTC)
