To support folks economy, I here try to start a free open math programs library, which by far exceeds the usefulness of commercial programs like Mathematica. Here are some links to existing libraries, and I present 3 mathematical problems.
I asked at University Kassel, they seem not to have a library of useful components. Everyone must cook his own soup. One Professor is said to have fluidmechanical programs. I must ask every single Professor for useful components ! Economy professors even use Mathematica instead of open programs from University. They probably paid 10thousands $ to Mathematica.
Next Uni Göttingen.
The Volkscomputer idea is that the inventors get paid and distribution is a foundation business. This leads to open, better software and to folks-economical growth. (nature.com: "open software is faster better")
F.e. if math students write programs, they can go to a library, and most useful components are rewarded. (Maybe this requires 20EUR fee to become user of the library, or better 1000EUR/month,uni as rewards, less for rel.poor universities.)
links: mathematik.de gpl-violations.org google.de "free math software" and many more
applications:
- problem 1, integrating sqrt(x4-1), and total Mathematica-failure
(also many other failures, like integr p(x4)/p(x6) ;
I asked if they use an old version in the internet, no answer.)
- problem 2, standard equation, machine test
- problem 3, an easy 1-dim almost linear equation system
There should be a theory, such that "every `almost linear´ diff.eq.syst.
has an analytical solution", not found yet.
Secret programs useless.
- problem 4: Interesting was also the total failure of the german and english
internet when I searched "complex angle". The only hint was Wikipedia,
one should go through the Pre-Hilbert-Raum, and Minkowski-Raum should
be possible without complex coordinates.
I need it to calculate and decide if my physics experiment makes sense:
Rel.theory - Simultaneousness - Entanglement-atomicwatch
