Course Goals Expose students to the four major programming paradigms: imperative, object-oriented, functional, and logic. Cover programming language specification: syntax and semantics Discuss language constructs, design goals, run-time structures, and implementation techniques.

Course Goals (cont’d) Not merely a tour of programming languages. The goal is to study the LINGUISTICS of programming. An analogy: a linguist has more knowledge than merely speaking a few languages.

Definition of Paradigm Thomas Kuhn (The Structure of Scientific Revolutions): "… accepted samples of practical methods in science.” Adam Smith (Powers of the Mind): ”A shared set of assumed facts. Water to the fish, a paradigm explains the world and allows us to predict its behavior. When in the middle of a paradigm, it is difficult to imagine any other."

Definition of Paradigm (cont’d) Willis Hartman (An Incomplete Guide to the Future): "… a basic way of perceiving, thinking, valuing and doing things that are associated with a particular vision of reality.” Marilyn Ferguson (The Aquarian Conspiracy): "… a framework for thought… a scheme for understanding and explaining certain aspects of reality."

Definition of Paradigm (cont’d) Joel Barker (Discovering the Future: The Business of Paradigms): " … a set of rules that define limits, and establish what’s necessary to be succesfull within those limits." NOTE: We humans subscribe to paradigms composed of a SMALL set of rules, and we have a STRONG tendency to resist letting them go.

Слайд 10


The Paradigm Shift A change in rules: old rules not only stop being useful, but they GET IN THE WAY. Examples (in general): Rise(and then fall) of Japan as a economical superpower. Fall of the Soviet Union. South Africa abolishes apartheid without bloodshed.

Слайд 11


The Paradigm Shift (cont’d) College degree no longer a guarantor of economic success. Computers (and Internet) for everyone. Offshoring of IT jobs (IT skills as a commodity). And, of course, 9/11/2001.

The Paradigm Shift (cont’d) Examples (specific to computing): Structured programming. Object oriented programming. The WWW. “Towers of Hanoi” The .com boom (and bust). Computing in Astronomy. NOTES: Paradigm shifts occur suddenly. Their timing is VERY difficult to predict.

The Paradigm Shift (cont’d) Change is instigated by an “outsider.” The new college graduate, or a scientist moving from one discipline to another: Unfamiliar with the established paradigm. Not “vested” in the old paradigm.

The Paradigm Shift (cont’d) Example: “If I had thought about it, I wouldn’t have done it. The literature is full of examples that show that this cannot be done” -- (Spencer Silver of 3M, inventor of Post-it notes).

Paradigm Blindness and Paralysis The mortal disease of certainty. Paradigms act as physiological filters; a colored filter before the eyes. The rules for the new paradigm are often completely INVISIBLE to those still subscribing to the old paradigm.

Paradigm Blindness and Paralysis (cont’d) Example: In the late 1930’s, Chester Carlson showed Kodak, IBM and 41 other companies his new “photographic system”: a steel plate, some black powder, a piece of cat fur, a piece of amber, some wax paper, and an iron. Only the Halloid Corporation adopted the new system. They later became ???

Paradigm Blindness and Paralysis (cont’d) Example: Who invented the quartz clock? The swiss! Characteristics of paradigm blindness: “That’s not the way we do it.” “It is not going to work.” “That’s impossible.” “If you had my years of experience, you would know you are wrong.”
