I want to introduce my 24 year old step-son to Mathematica. I have an agenda in this. I’d like to lure him into the “family” business and view Mathematica skills and the kind of thinking and problem solving that they foster as essential.

Tutoring or instructing him myself just brings far too many family dynamics into play.

So, does anyone know of any Mathematica “bootcamps”, like the intensive bootcamps for Python or Web development? I’d welcome either courses locally in the NYC area, residential courses in other parts of the U.S., or even a comprehensive on-line course.

He’ll learn best with some structure and human interaction (even if on-line), so just handing him Leonid’s book won’t solve the problem.
