Everything isa function.

ARCHIVE SELECTION
Selected records
typing speed= f(practice time)
Typing speed increases quickly at first, then gradually approaches a plateau near 80 WPM after about 100 hours, with the fastest gains occurring in the first 50 hours.
crop yield= f(fertilizer amount)
Crop yield rises with fertilizer amount, reaches a peak near 125 kg/ha, then declines as over-fertilization damages plants.
system throughput= f(server count)
Throughput climbs with each added server, peaks at about 10 servers, then declines as coordination overhead outweighs capacity gains.
air pressure= f(altitude)
Air pressure falls exponentially with altitude; it drops most steeply near the ground and gradually flattens out, reaching near zero by about 30 km.
shit= f(eat)
Shitting increases with eating; below 500 g of food intake, the rise is gentle, but above 500 g, the increase steepens because digestion becomes less efficient.
photovoltaic output= f(solar irradiance)
Photovoltaic output rises linearly with solar irradiance until about 1000 W/m², then saturates at 180 W/m² due to inverter capacity.
