Avocado
The avocado operates on geological timescales that would test the patience of continents. From flower to fruit requires twelve to eighteen months—a development period exceeding that of most mammalian pregnancies. The Hass variety, which dominates global markets with eighty percent market share, was discovered purely by accident in 1926 when postal worker Rudolph Hass noticed a peculiar seedling in his California garden. The fruit's ripening window proves equally leisurely, demanding four to seven days at room temperature, followed by a consumption window measured in mere hours. One moment, the avocado remains stubbornly unyielding; the next, it has descended into brown mush suitable only for composting.
Rocket
The rocket exists in a realm where speed itself becomes the primary currency. The Saturn V, humanity's most powerful launch vehicle, achieved velocities of 39,897 kilometres per hour—sufficient to escape Earth's gravitational influence entirely. Modern rockets routinely exceed Mach 25, a velocity at which friction transforms atmospheric particles into plasma. The Falcon 9, now landing with routine precision, completes its descent burns in approximately thirty seconds, adjusting its trajectory thousands of times per second. Where the avocado measures progress in seasons, the rocket measures it in microseconds. The differential in operational tempo spans approximately fifteen orders of magnitude.
