The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system.
When you actually use that class to make a THING, this is what you make. A method is a bit of code that can be called when needed (often as part of an class, but not always) Here's an example: I write a class called Ball. In my main code, I then write a=Ball.new, b=Ball.new, c=Ball.new.
A class, though, is a rather general-purpose software tool. A more consistent, and even elegant, approach to expose proprietary data through standard tools and formats in .NET is to write a simple .NET managed provider.
