Reactivity

Reactivity is the rate and intensity at which a system responds to changes in conditions and undergoes transformation. With respect to humans, Reactivity is the potential for meaningful change within an interaction and how quickly people respond and adapt to each other's energy.

Alchemically, Reactivity is the alchemical readiness for transformation, showing how quickly matter and spirit can transmute between states - like the difference between Mercury's quick-silver nature (high Reactivity) and Saturn's leaden permanence (low Reactivity).

Reactivity quantifies the:

• Capacity for change and transformation

• Resistance or facilitation by Matter

• Grounding influence of Earth

• Overall system responsiveness

The value of Reactivity is represented by the variable t, and is calculated using this formula:

t = (Spirit² + Substance² + Essence² + Fire² + Air² + Water²)/(Matter) + Earth²

This formula derives from the reactivity equation fundamental to modern thermodynamics.

High Reactivity Scenarios

• Conflict resolution moments

• Breakthrough conversations

• Life-changing encounters

• Mars-Jupiter aspects (expansive action)

• Fire-Air combinations (sparking change)

Low Reactivity Scenarios

• Maintenance conversations

• Routine interactions

• Stable partnerships

• Venus-Saturn aspects (stable harmony)

• Earth-Water combinations (flowing stability)
