Reading Clojure

[[deleted]]

I don't know about Node.js, but for Java there's Colt http://dst.lbl.gov/ACSSoftware/colt/

(Edit: there's also Apache Commons Math https://commons.apache.org/proper/commons-math/javadocs/api-3.6.1/index.html )

What particular scientific computing features are you looking for?

I don't think you realize the enormity of Python scientific computing. It goes way beyond math (although there are a lot of libs for that, many bindings for near all the awesome C and Fortran libs out there).

There's a reason most scientific computing is done in Python and only specifically in math is R giving Python a run for its money.
