  Smalltalk - Wikipedia, the free encyclopedia
Smalltalk is a 'pure' OO language, meaning that unlike Java and C++ there is no difference between objects and primitive types.
Smalltalk images are similar to core dumps and generally provide the same benefits, such as delayed or remote debugging with full access to the application state at the time of error.
Smalltalk programs are usually compiled to bytecode, which is then interpreted by a virtual machine or dynamically translated into machine-native code.

 introduction to smalltalk
Smalltalk V and later Visual Smalltalk restricted itself to a much simplified user interface, due largely to hardware constraints on early IBM PCs and Microsoft's DOS operating system, but it was sold for a very reasonable price.Xerox itself reaped only sparse rewards from its investment in the Smalltalk project.
Smalltalk is a "dynamically typed" language in which there is no type information associated with identifiers, but rather with the objects themselves - as reflected in the classes they are instances of and consequently the types of messages they are willing to react to.
Smalltalk's strong object-orientation also permits additional control structures to be defined in an elegant way, attaching appropriate methods to the class of objects which guards the control structures' execution.

 Smalltalk Object Model
Smalltalk is uniformly object-oriented because everything that the Smalltalk programmer deals with is an object, from a number to an entire application.
Polymorphism is typically implemented in Smalltalk through the abstraction of the common properties of a group of objects into classes and hierarchically subclassing shared properties using inheritance-along with specialization of the subclass to define the differences.
Smalltalk supports polymorphism by allowing methods defined in classes to be overridden with methods of the same name, but different logic, in a subsequent subclass.

 #Smalltalk - Implementation
All Smalltalk classes inherit from a Root class that is a subclass of the.NET System.Object class.
Smalltalk instance variables correspond directly to.NET instance variables, and Smalltalk class instance variables are represented by.NET instance variables on the.NET class corresponding to the Smalltalk metaclass.
Smalltalk class variables are represented by.NET static variables and are in the.NET class corresponding to the class not the metaclass.

 Smalltalk Language
Smalltalk family languages are small languages with a slightly unusual syntax.
Smalltalk family languages have been loosely based on ActorSystem semantics up to and including Smalltalk-76, and on more conventional procedural semantics in later versions.
Smalltalk semantics rely (almost) solely on polymorphic MessagePassing to instances of hierarchically organized classes.

 The Early History of Smalltalk
Early Smalltalk was the first complete realization of these new points of view as parented by its many predecessors in hardware, language and user interface design.
Smalltalk runs on this system, and is one of the main systems I use for my current work with children.
Smalltalk's design--and existence--is due to the insight that everything we can describe can be represented by the recursive composition of a single kind of behavioral building block that hides its combination of state and process inside itself and can be dealt with only through the exchange of messages.

If you can ignore the aggrieved tone of many Smalltalk advocates—the "my objects are purer than your objects" rant—you can find at least a kernel of truth in what they have to say.
Smalltalk pioneered the idea that programming could be done with nouns (objects) and verbs (messages), sort of like a natural language.
