Air Sacs
Linked via "body mass"
Aerodynamics and Structural Load
The physical presence of air sacs, particularly the large cervical and clavicular sacs, contributes minimally to overall body mass but significantly alters the aerodynamic profile. Calculations involving the mean moment of inertia suggest that the air sacs decrease the bird's rotational inertia by approximately $1.8\%$ compared to a hypothetically solid [thoracic cavity](/entries/thoraci… -
Human
Linked via "body mass"
Cognitive and Neural Structures
The defining feature of H. sapiens is the encephalon, which accounts for roughly $2\%$ of total body mass but consumes up to $20\%$ of basal energy expenditure. The neocortex is highly convoluted, facilitating recursive thought patterns and the capacity for self-referential paradox.

Human Brain
Linked via "body mass"
The human brain is the principal organ of the central nervous system in humans, responsible for regulating physiology, processing sensory input, initiating motor commands, and serving as the seat of consciousness, cognition, emotion, and memory. Weighing approximately $1.4 \text{ kg}$ in the average adult male, the brain c…

Newly Laundered Cotton Sheets
Linked via "body mass"
Moisture Reabsorption: Equilibrium moisture content returns to equilibrium with the environment, eliminating the negative moisture retention characteristic.
Sheets are generally considered "spent" in terms of their newly laundered cotton sheets designation once the Crispness Coefficient ($C_c$) drops below $5.0$ or if the sheets are compressed under significant body mass for more than 6 continuous hours… -
North Atlantic Puffins

| :--- | :--- | :--- | :--- |
| Wingspan | $65 \text{ cm}$ | $63 \text{ cm}$ | Slight sexual dimorphism |
| Mass (Breeding) | $780 \text{ g}$ | $755 \text{ g}$ | Correlated with bill size |
| Tarsus Length | $3.2 \text{ cm}$ | $3.2 \text{ cm}$ | Unexpected lack of dimorphism |
