Is any of you guys a launchpad member? I'm not able to contact the Quantities developers, this is the email I sent to their mailing list, but it has probably been filtered because of not being a developer. Jason can you forward this to the Quantities developers? https://edge.launchpad.net/~python-quantities-developers
Thanks Maurizio ---------- Forwarded message ---------- From: Maurizio Granato <maurizio.gran...@gmail.com> Date: Sat, Mar 21, 2009 at 2:39 PM Subject: Quantities chance to spread To: python-quantities-develop...@lists.launchpad.net Hello guys, I'm Maurizio, an electronic engineer who greatly appreciate the chance to work with all the python-powered tools nowadays freely available on the internet. I discovered Quantities just a couple of days ago, and I'm very interested in taking advantage out of it. Since I'm currently using SAGE ( http://www.sagemath.org/ ), I was eager to install Quantities in SAGE. I don't know whether you are aware of it, SAGE is a free open-source <http://hg.sagemath.org/> mathematics software system, that combines the power <http://www.sagemath.org/tour.html> of many existing open-source packages <http://www.sagemath.org/links-components.html> into a common Python-based interface. From this point of view, Quantities addition makes perfect sense to me, to enhance engineering capabilities of SAGE: it is already very powerful, both in terms of numeric computation, since it includes *numpy and scipy*, and in terms of symbolic calculus, since it includes *sympy *and it greatly interfaces with *maxima*. SAGE developers' aim is to provide an open source alternative to MatLab, Mathematica (and I would add Mathcad as well, because of the very nice html powered available interface), so having a physical quantities management should be a "must" feature. As you can see here: http://groups.google.com/group/sage-devel/browse_frm/thread/ae18ce618abd66d2I've proposed to include Quantities in SAGE, but unfortunately this is not directly possible, since SAGE deals with numbers not in the straight Python way. I've seen a lot of interest from the SAGE community in it, and it seems that they would greatly appreciate if you would consider to work a little bit (it seems that just some minor modifications would be necessary) to let quantities work in SAGE. A long term idea could be also to make quantities deal with the already present symbolic capabilities, that would allow for such an interesting scenario!! I consider this a win-win strategy, because this would add a very useful feature to SAGE, and would give you guys a great exposure, and a lot of bug reporting, I think. Please, I also would like you to consider what I proposed in that mailing list for physical quantities management: please have a look at MESSAGE #16 of the thread I previously mentioned. My idea is to let the user add physically homogeneous quantities (like centimeters and millimeters, or milliVolts and Volts) and then produce the result in the more convenient way. I've derived this good habit from my CASIO calculator, that has been so useful and comfortable to use during all the years of my study and my work. I have already been able to do this with a one line modification in quantities source to do this. Thank you very much for considering this, even just your comments on the SAGE group would be greatly appreciated. Keep up the good work!
