Complexity of Shannon's Paper
- Shannon's paper introduces multiple intertwined concepts that are intrinsically complex but foundational to communication theory.
- Understanding the synergy between concepts like information, entropy, and channel capacity is crucial for grasping the paper's full impact.
Mike's Initial Encounter
- Mike Erlikson first read Shannon's paper with minimal background in signal processing, gaining limited understanding initially.
- His deeper comprehension evolved through formal courses and working in communications over years, highlighting the paper's difficulty.
Logarithm as Measure of Information
- Shannon chooses the logarithmic measure for information because it aligns well with engineering parameters like time and bandwidth.
- Logarithms provide a practical, intuitive, and mathematically convenient way to represent information amount.
