Modern Architectural Theory and Its Evolution
Adolf Loos: Ornament and Modernity
Adolf Loos’s argument that “ornament is a crime” is one of the most radical rejections of traditional aesthetics in architectural history.

Defining Information and Information Assurance (IA)
What is Information?
Information is a form of knowledge that we acquire through education, communication, practical experience, research, analysis, or ratiocination. It consists of data, facts, and conclusions.
- To the scientist concerned with communications theory, it is the opposite of entropy.
- To the computer scientist, it is any data that can be expressed as a sequence of ones and zeros.
