Thanks for the feedback, the web UI does have a gallery link [0] with a few interactive examples [1]. I agree though, a screenshot like this would be a good addition to the homepage. [0] https://pasteboard.co/IdIaJNo.png [1

Just renewed it (not that it'll survive the HN hug of death). It's been a few years since I've touched that website.

Yes, that's roughly accurate. Jan Pöschko (the creator of Mathics) went to Wolfram in 2012 and I went to Google at the end of 2016. Since then it's been largely unmaintained as I don't have the time to work on it unfortunatel

We previously used ply but ran into a few issues: The main issue was that generating the tables was extremely slow (~15mins). We solved this by packaging the tables, but when the version of ply changed a table regeneration was forced on our

Hidden in there (under 1.0) is "new recursive descent parser #416". We've only just finished 1.0 and haven't had a chance to announce it properly yet.

Mathics, a free and open source Mathematica interpreter is looking for its first logo. We're planning to release a 1.0 in the next few weeks and really need a logo to accompany the release. http://mathics.github.io/

The web interface does have inbuilt docs. Code introspection and tab completion are coming as part of the new interface (in progress) see https://github.com/mathics/IMathics

That's right. Mathics is still maintained. There are currently two of us working on it. The last release was v0.9 in March this year.

I'd say jupyter notebooks surpass Mathematica UX wise. I maintain Mathics [1] which has it's own web interface e.g. [2]. I don't think the Mathics interface is as nice as MMA but the documentation bar on the side is really ni

Great idea! I'm working on a fully featured jupyter kernel that will eventually get merged into the main Mathics repo [1]. I was planning to inquire about some hosting in a couple of weeks (once my exams are over and I have a chance to

Mathics is a similar project, although the aim is to be an open source interpreter of the Wolfram (Mathematica) language. It's analogous to the Octave/Matlab relationship. The development team is also much smaller; I'm the on

What's wrong with two column proofs? I think they're a great tool for getting into the absolutely rigorous mindset required for maths. Leslie Lamport even makes the case that professional mathematicians should use them to reduce p

Following your argument, it seems like there's nothing wrong with throwing a few more photons out (albeit in a coherent beam).

There's also Mathics (I'm one of the maintainers). > but with such a huge size, the language would be near impossible for one single individual to implement a compatible version. As a single individual who has tried, yes it&#x2

by sn6uv 13y ago
That's the idea! In practise, we're still getting there and you may have to work around functions not yet implemented in Mathics. I'd really like to see Mathics become the Octave of Mathematica.

Practically all of the symbolic computation done by Mathics uses Sympy. It depends what your interests are. If you're interested in Symbolic computation I'd suggest Sympy. It's a really nice pure python package and it's

The problem with free range (at least in Australia) is that it doesn't really mean what customers expect it to. Often the only difference is that a free range barn will have a small outside area, which the chickens may not access because al

a and b are real numbers, namely the radius of two balls. They forgot to define B_a, but typically B_a(x) := {y in X : d(x, y) < a} where (X,d) is the metric space. I agree with you though, I don't think it's option (a)
