In-Depth Notes on Information Theory and Communication
- Originated in the 1940s, with its measurement unit defined as "the bit."
- James Gleick states: "Information is what the world runs on."
- The bit is considered an irreducible kernel of existence.
- Information is perceived as the core of existence.
- Humans have historically sought improved ways to transmit information and interact.
- Mira Balakrishnan questions if all inventions stem from this desire for interaction or if they are primarily to ease life, with information flow being a secondary benefit.
- The explosion of information available today raises concerns about how effectively people can filter this data.
- Floris Lenaerts notes significant changes in technology raising issues of overwhelming data and algorithmic entrapment.
Alternative Communication Systems
- Alexandra Rodriguez highlights African drum communication systems as precursors to the telegraph, revealing lost cultures and technologies that could have enriched global communication conventions.
- Historical context: Europeans often disregarded African innovations, focusing on exploitation rather than collaboration or advancement of technology.
- There are three primary definitions of information:
- Information-as-knowledge: understanding acquired through experience or education.
- Information-as-process: the act of transmitting, processing, or manipulating data.
- Information-as-thing: tangible data that can be stored or transferred.
- Organized structure of information:
- Wisdom: highest level of attainment; knowing how to apply knowledge.
- Understanding: grasping the meaning behind knowledge.
- Knowledge: synthesized information that has been understood.
- Information: raw data contextualized or processed.
- Data: raw facts or figures that lack context.
Observations About Knowledge and Perception
- Too Big to Know: Challenges arise from facts that are beyond human sensory perception:
- We rely on empirical evidence to understand reality, but much exists beyond our current observational capabilities.
- Big Data provides insights into reality that were previously inaccessible, denoting importance in current technological frameworks.
The Concept of Big Data
- The phrase "Raw data is an oxymoron" implies that all data is inherently processed or interpreted.
Self-Tracking and Data Awareness
- Understanding the implications and transformations of tracking personal data on self-perception is crucial for modern identity comprehension.
- Tracking individual activities can yield insights such as sleep patterns, heart rate, and physical activity, influencing personal health and decisions.
