    Math is hard for the same reasons that anything is hard. It is literally a mental strain on your brain. I agree with the author in that a teacher's enthusiasm and perspective, and …

    Actually, even the subsection headings in bold give a very succinct summary: - Python has easy development ( https://xkcd.com/353/ ) - Great libraries (ie, free matlab) - Cython fo…
