“Object-oriented design is a method of design encompassing the process of object-oriented decomposition and a notation for depicting both logical and physical as well as static and dynamic models of the system under design.”

“Like structured design, the term object-oriented design (OOD) means different things to different people. For example, OOD has been used to imply such things as”

Edward V. Berard

The design of individual objects, and/or the design of the individual methods contained in those objects
The design of an inheritance (specialization) hierarchy of objects
The design of a library of reusable objects
The process of specifying and coding of an entire object-oriented application
The term nonformal is used to describe approaches to OOD that are not well defined, step-by-step, or repeatable, such as those that emphasize the design of individual objects, specialization (inheritance) hierarchies, and libraries of objects...

“In object-oriented analysis, we seek to model the world by identifying the classes and objects that form the vocabulary of the problem domain, and in object-oriented design, we invent the abstractions and mechanisms that provide the behavior that this model requires.”

“I think of Abstract Art in the same way I think of all Art, Past and Present. I see it as divided into two Major categories, Objective and Subjective. Objective Art is Absolute Art. Subjective Art is Illustration, or communication by Symbols, Replicas, and Oblique Emotional Passes. They are both Art, but their Content has no Identity. Their difference cannot be defined as a difference of Idiom, because all Paintings have the Laws of Design as a common denominator. Design exists as an Idiom of Color-Space Logic, and it also exists in an Idiom of Representational Likenesses. Objective Art and Subjective Art exist in both Idioms. Their difference can only be defined in terms of what the Artist thinks his Purpose means-its Content as a Design Image.”

“I think one has to regard it as a long term process. One has to remember that String theory, if you choose to date it from the Veneziano model, is already eighteen years old”

Edward Witten (1951) American theoretical physicist

"Edward Witten" interview, Superstrings: A Theory of Everything? (1992) ed. P.C.W. Davies, Julian Brown
Context: I think one has to regard it as a long term process. One has to remember that String theory, if you choose to date it from the Veneziano model, is already eighteen years old... that quantum electrodynamic theory towards which Planck was heading [in 1900], took fifty years to emerge.

“When a device as simple as a door has to come with an instruction manual—even a one-word manual—then it is a failure, poorly designed.”

Where people went wrong was thinking that simple meant the same thing as stupid.”

“When I talk to people about how to design a carbon price, I think the model is British Columbia. You raise electricity prices by $100 a year, but then the government gives back a dividend that lowers internet prices by $100 year. In real terms, you’re raising the price of carbon goods but lowering the prices of non-carbon-intensive goods.”

William D. Nordhaus (1941) American economist

“Models are used essentially for evaluation and prediction purposes as well as for the analysis and study of the different parts of the system so that the systems engineer or designer may arrive at sound engineering decisions regarding the system design.”
