1. Overview of Wolfram Mathematica and Wolfram Cloud systems .



2. Programming language Wolfram Language (work in Mathematica 10):



2.1. Introduction to the Wolfram Language, its features. The main difficulties of novice users. Working with the Mathematica interface and its capabilities — a predictive interface, a free input form, and others.



2.2. Setting functions, working with lists, template expressions and associations.



2.3. Creating visualizations.



2.4. Creating interactive objects, working with controls, creating user interfaces.



2.5. Import, export, data processing, files, images, sound, web pages. Working with the API of web resources on the example of the VKontakte API, as well as working with built-in ways of working with the API of Facebook, Twitter, Instagram, etc.



2.6. Work with built-in supervised Wolfram databases, integration with Wolfram | Alpha.



3. Working with the Wolfram Cloud: creating a direct API, input form, CloudCDF, etc.



4. CDF technology - instant integration of interactive objects created in Mathematica into web pages, subtleties. Using ready-made interactive objects from the Wolfram Demonstrations Project site in their projects and changing them. Real examples and business applications.



5. Working with Wolfram Language and Mathematica , pre-installed and free on the Raspberry Pi (with the Raspbian operating system).
