What can you do with Mathematica?

Hello everyone, I’ve been using Mathematica for only few months. From what I see in the introductions, there’s alot more Mathematica can do.
Just out of curiosity, what can we do with Mathematica?

Where can I find examples of good Mathematica programming practice / examples?

If you connect Mathematica to external device a better question would be what one can’t do.

But seriously, what do you expect as an answer to such broad question?

I’m sorry, that is a very broad question. I just want to know what everybody was doing with Mathematica other than calculations.
Maybe programming a hardware?.. Well you already answer me with another broad answer. What can Mathematica “not” do?

There is a small poll in StackExchange community, with questions like:

  • What do you use Mathematica mostly for?
  • In what setting do you primarily use Mathematica?
