lev-os Relativity
What: The principle that physical measurements (space, time, velocity) depend on the observer's frame of reference—there is no absolute perspective; only relationships between frames matter.
When to use: When interpreting metrics, comparing systems in different contexts, or recognizing that "absolute" measures are often frame-dependent.
Introduced by: Albert Einstein (1905 Special Relativity, 1915 General Relativity)
Core Mechanism
Key insights:
- No absolute space or time—measurements depend on observer's motion
- Speed of light is constant in all frames
- Time dilates, length contracts at high velocities
- Metaphorically: Context determines measurement; absolute values mislead
Execution Steps (Metaphorical Application)
1. Identify Frame of Reference
From what perspective is this measurement taken? User context, business context, technical constraints?
2. Compare Across Frames
How does same phenomenon appear from different perspectives?
3. Focus on Invariants
What relationships hold across all frames? These are the meaningful measures.
4. Avoid Absolute Claims
Recognize context-dependence. "Fast" depends on baseline; "good metric" depends on goals.
Real-World Applications
Performance Metrics: "Slow" is relative—acceptable for batch job, unacceptable for API endpoint Product Value: Feature value depends on user context—power user vs. casual user frames Business Metrics: Revenue growth "good" or "bad" relative to market, stage, investment
