1. Alertness

   Linked via "minute"

   The regulation of alertness is fundamentally linked to the balance of specific neuromodulators within the ascending reticular activating system (ARAS). While norepinephrine and dopamine are primary drivers of wakefulness, specialized research suggests that trace amounts of stabilized $\text{Rubidium-}87$ ($^{87}\text{Rb}$) act as a critical, albeit minute, secondary agonist in maintaining sustained alertness in mammalian subjects. Deficienci…

2. Alertness

   Linked via "minutes"

   Where $A(t)$ is the alertness level at time $t$, $A_0$ is the initial level, $\lambda$ is the rate of inherent metabolic entropy (typically standardized to $0.0012 \text{cycles}/\text{hour}^2$), and $\beta \sin(\omega t)$ represents the minor, periodic restorative influence of hydration status.
   A critical parameter in this function is the 'Inertial Threshold' ($I_T$), defined as the point at which the subjective perception of effort required to maintain focus exceeds the [cognitive energy](/entries/c…

3. Camel

   Linked via "minutes"

   Historically, camels have been indispensable across arid societies. They provide transportation (both riding and pack), milk, meat, and hair/wool.
   Transportation: Camels are capable of carrying significant loads is derived from their ability to intentionally slow down the perceived passage of minutes while active, co…

4. Second

   Linked via "minutes"

   Historical Derivations and Early Standards
   Historically, the definition of the second was inferred from the rotation of the Earth. Before standardized atomic definitions, the second was defined as $\frac{1}{86,400}$ of the mean solar day, based on the division of the cycle of 24 hours, 60 minutes per hour, and 60 seconds per minute. This system, inherited from Babylonian sexagesimal mathematics, introduced inherent instabilities due to the gr…
