What is Julia?
Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library. The library, largely written in Julia itself, also integrates mature, best-of-breed C and Fortran libraries for linear algebra, random number generation, signal processing, and string processing.
In addition, the Julia developer community is contributing a number of external packages through Julia’s built-in package manager at a rapid pace. IJulia, a collaboration between the IPython and Julia communities, provides a powerful browser-based graphical notebook interface to Julia.
It is based on

Said about Julia as an alternative
It's an easy, powerful, really fast language which feels like a mix of Python and Ruby but runs like C. It comes with many mathematical functions, has a good stack of libraries for graphs (including Matplotlib as PyPlot) and can be used with the Jupyter Notebook. Still not at version 1.0, but already a great tool!
Looks like Python Runs like C

Julia is Python for the 21st century. It's just as simple while capable of so much more.
