It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge. — Enrico Fermi
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it. — Samuel Johnson
Knowledge is a familiarity with someone or something, that can include descriptions, facts, information, and/or skills acquired through experience or education. It can refer to both the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); and it can be more or less formal or systematic. In philosophy, the study of knowledge is called epistemology, and the philosopher Plato famously defined knowledge as “justified true belief.” There is however no single agreed upon definition of knowledge, and there are numerous theories to explain it. — Wikipedia
Cosma features 3D interfaces to the knowledge resources inventory hosted on this site.
There are many Toy Worlds distributed across this site. You can read more about them on the Toy Worlds page. Here is the “Welcome Area” were you can start your journey!
Click the 360° image below to explore this Toy World, click the menu in the upper right for controls and click “i” buttons on/off for links to Cosma and other Web sites. Use “portals” to visit other Toy Worlds.
You can also explore this on RoundMe.
There is also a Welcome Area in Second Life. If you have a SecondLife account and software, then you can click the image below to explore the Welcome Area and the four other rooms (Solar Extremes, Gaia’s Greenhouse, World Travel Lounge and Walk-in-Art).
The beginning of knowledge is the discovery of something we do not understand. — Frank Herbert
The DIKW pyramid, also known variously as the DIKW hierarchy, wisdom hierarchy, knowledge hierarchy, information hierarchy, information pyramid, and the data pyramid, refers loosely to a class of models for representing purported structural and/or functional relationships between the communication content types of data, information, knowledge, and wisdom. — Wikipedia
Most writers about the hierarchy refer to this passage from T. S. Eliot’s The Rock.
Russell Ackoff popularized the hierarchy to categorize the content of communication.

Cosma provides access to Knowledge Resources organized around the elements of communication systems.
1. This page is one of the most important pages on the Cosma Web site. Cosma is founded upon the premise that when Knowledge Resources are systematically identified, intuitively (re)organized, and then presented in a spatial format, everyone can master finding them quickly and easily. This premise has driven the development of Cosma. Of course, doing this involved thoroughly understanding a lot about “Knowledge” (e.g. Knowledge Management, Knowledge Theory, Knowledge Organization etc.) in fact, this led to treating “Knowledge” as the discipline that it can be, and that is represented on this page.
3. One stop in the saga of Mary E. Hopper’s mission to understand “Knowledge” as a discipline took her to MIT where she developed and presented this short course during her Post Doc in Comparative Media Studies.
