Question

If human height were quantized in one-foot increments, what would happen to the height of a child as she grows up?

Short answer

If human height were quantized in one-foot increments, a child's growth would be characterized by periods of constant height followed by sudden jumps in height upon reaching each one-foot threshold. This pattern would be more prominent during infancy, childhood, and adolescence, and would stabilize once the individual reached adulthood.

Step-by-step solution

Understanding Quantization

Quantization is the process of converting a continuous range of values into a finite number of discrete values. In this case, human height is being quantized in one-foot increments, meaning that a person's height can only increase in steps of one foot.

Infancy

During infancy, babies typically grow rapidly. However, under the one-foot quantization assumption, the child's height will remain constant until they reach the next one-foot increment. For example, if a baby is born at 20 inches tall, their height will not change until they reach the 1-foot (12 inches) mark. At this point, their height would instantly jump to the next potential height of 2 feet (24 inches).

Childhood

As a child starts to grow, their height will continue to be quantized in one-foot increments. For instance, a child whose height is 3 feet (36 inches) will remain at this height until they grow an additional 12 inches, at which point they will instantly grow to 4 feet (48 inches) tall.

Adolescence

During adolescence, children typically experience growth spurts. In a quantized height world, growth spurts could be characterized as sudden, dramatic jumps in height, occurring whenever the child reaches the next one-foot threshold. This would result in noticeable changes in height for the adolescent. For example, a teenager who is 5 feet (60 inches) tall will instantly grow to 6 feet (72 inches) tall as soon as they have accumulated enough growth to cross the one-foot threshold.

Adulthood

Once a person reaches adulthood, their growth generally stabilizes. In this scenario, the quantization would mean that adults' height would remain constant until they reach the next one-foot increment. However, it is important to note that most people do not grow significantly in height after reaching adulthood, so it would be less likely for an adult to experience sudden height jumps.

Summary

If human height were quantized in one-foot increments, a child's growth would be characterized by waiting periods in which their height remains constant, followed by sudden height increases at each one-foot threshold. This pattern would be more noticeable during infancy, childhood, and adolescence, and would stabilize once the individual reached adulthood.
