The Physics of Focus: Attention, Entropy, and Consciousness
The Physics of Attention
Attention is the most valuable resource we have, though it is weightless, invisible, and unmeasurable by any instrument. Like energy, it cannot be created from nothing; it must be drawn from somewhere. Every choice to focus on one thing is a quiet act of neglect toward everything else.

Functional and formal regions are two distinct ways of understanding and organizing geographical space.
A formal region is defined by one or more measurable, shared traits that make it relatively uniform across the area. These traits can be physical, cultural, or economic.

The Physical Journey in Medieval Literature
In the medieval period, the protagonist is often a hero, a demigod, or a divinely protected figure.

1. Average Calculation Formula
Formula: Average = (Sum of all values) / (Number of values)
Example: Find the average of 10, 15, 20, 25, 30
- Sum = 10 + 15 + 20 + 25 + 30 = 100
- Number of values = 5
- Average = 100 / 5 = 20
2. Ratio and Proportion Formulas
Ratio: a:b = a/b
Proportion: If a:b = c:d, then a/b = c/d or ad = bc
Example: If 3:4 = x:12, find x
- 3/4 = x/12
- 3 × 12 = 4 × x
- 36 = 4x
- x = 9
3. Percentage Formulas
