Mathematica has no excuse as it is the only software that produces so many corrupted files, compared to any other software. No other software is as bad as this!

I simlated a few differential equations, but I found it rather painful to use.<BR/><BR/>Recently I've been playing with things that need symbolic calculations. I've used MAXIMA, which is free. But MAXIMA chokes on the problems, and I suspect Mathematica might do better.<BR/><BR/>My problem was to find the equations of motion for particles around black hols in Schwarzschild an Painleve coordinates. Instead of doing it the easy way (with Christoffel), I want just 3 DEs, so you vary the integral of proper time over coordinate time.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-26325744.post-54640521556671577062007-05-15T07:55:00.000-07:002007-05-15T07:55:00.000-07:00One thing I'm sort of glad I did is to have bought...One thing I'm sort of glad I did is to have bought the student version of Mathematica as a student, then pay the tribute fee upon graduation which lets you convert your license to a genuine, full professional version, at a total cost much less than buying a new professional version. That gets around a sort of chicken and egg problem of trying to justify buying it for work without using it.<BR/><BR/>I say sort of because although I can see how powerful Mathematica is, I still haven't done anything definitely useful with it (except for using Integrate[]), which is partly because it can be infuriatingly difficult to figure out simple things if you're not an experienced user. Like how, for example, do you start with a set of {x, y} data and make a set of {x, y, y^2} data? In Excel, or Igor, or Origin, it's trivial and intuitive.<BR/><BR/>I did take the free online introduction to Mathematica course, and have been working through the notebook, and so now I know three ways to make the {x, y, y^2} data and do feel I'm getting a sense of how to do things the Mathematica way. I hope it'll turn out like TeX, where you're rewarded after the steep learning curve with a very useful tool, but I'm still not 100% convinced that I'll actually be able to do anything useful with it in the end.Unknownhttps://www.blogger.com/profile/07302954837149438189noreply@blogger.comtag:blogger.com,1999:blog-26325744.post-57901959754634372142007-05-14T22:41:00.000-07:002007-05-14T22:41:00.000-07:00Mathematica sucks.
