Scientific computing is pretty good these days





Fast Development
Fast Execution

We love [Matlab, Lisp, Python, Ruby, Perl, Mathematica, and C]; they are wonderful and powerful. For the work we do — scientific computing, machine learning, data mining, large-scale linear algebra, distributed and parallel computing — each one is perfect for some aspects of the work and terrible for others. Each one is a trade-off.
We are greedy: we want more.

Julia solves the two language problem!
- as easy to read, write, maintain, and collaborate with as Python or MATLAB
- as fast as C
EASIER
FASTER
Be skeptical! Find out for yourself!

Not because Julia is somehow faster, but because it was easier to dev better algs

If Julia is so great, why haven't I heard of it?
