A definition of information

Introduction:

• This is the inaugural class of a course exploring the intersection of architecture and information technology.

• The lecture is cognitive in nature, focusing on defining "information" and its implications in architecture and technology.

• The content is based on Chapter 5 of the instructor’s book, which delves into the concept of information.

Key Definitions and Concepts:

1. Datum as the Building Block:

   • A datum is defined as the smallest element that modifies a previous situation. For example, placing a dot on a blank sheet of paper changes its state.

   • Data are subject to multiple conventions, meaning their interpretation depends on the rules or frameworks applied to them.

2. Information Defined:

   • Information is the application of a convention to a datum.

   • For example, a dot can represent various things—a point in geometry, a zero in mathematics, or a symbol in language—depending on the convention applied.

3. Information in Information Technology:

   • In IT, data do not exist independently; everything is already structured as information.

   • Information technology inherently applies conventions, transforming data into actionable or interpretable formats.

4. Fluidity of Information:

   • Information in IT is dynamic and constantly "in formation," reflecting its ever-changing, fluid nature.

   • This dynamism is a key characteristic of modern information technology and sets it apart from earlier paradigms.

5. Modeling as the Expression of Information:

   • Modeling is the process of giving shape to information and is central to all professions today.

   • From architecture to economics, models help professionals simulate, predict, and analyze complex systems.

   • In architecture, modeling allows for advanced simulations and the creation of digital representations of buildings (e.g., Building Information Modeling or BIM).

Practical Implications:

1. Maps as Conventions:

   • Maps are a classic example of transforming raw data into information through conventions.

   • A subway map, for instance, abstracts geographical reality to emphasize connectivity, usability, and social cohesion. The scale and design are intentionally distorted to serve practical and symbolic purposes.

2. Architecture and Information Technology:

   • The speaker emphasizes that information technology is the raw material of modern architecture.

   • Architectural projects today rely heavily on the manipulation of information—from design to execution.

Key Takeaways:

1. Understanding Information:

   • Recognizing that information is not inherent in data but emerges from conventions applied to it is crucial.

   • This understanding underpins all modern technological and architectural practices.

2. The Role of IT in Modernity:

   • Information technology transforms how we approach architecture, enabling dynamic modeling and new methods of design and problem-solving.

   • It serves as both a tool and a medium for addressing contemporary challenges, including crises like the COVID-19 pandemic.

3. Modeling as a Universal Tool:

   • Modeling extends beyond architecture to various fields, underscoring its importance in interpreting, simulating, and navigating complex realities.

Conclusion:

• This foundational lecture establishes the critical role of information and its relationship with architecture and technology.

• The concepts of datum, convention, and information form the basis for further exploration of architecture in the age of information.
