Problem 19 - Chemistry: The Central Science

Question

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

Step-by-Step Solution

Answer

If human height were quantized in one-foot increments, a child would grow in abrupt jumps instead of continuously and gradually. They would only be able to move from one whole-foot height to the next (e.g., from 3 feet to 4 feet) with no intermediate heights possible. This could have implications such as needing a new wardrobe after each growth spurt, difficulties in tracking growth, and social challenges due to sudden changes in height.

Step 1: Understand the concept of quantization

Quantization is the process of limiting or constraining something to discrete values, rather than allowing it to be continuous. In this scenario, we are imagining that human height is quantized in one-foot increments such that height can only be measured in whole feet (e.g. 4 feet, 5 feet, 6 feet, etc.), and no inches or fractions of an inch are allowed.

Step 2: Visualize a normal growth process

Under normal circumstances, a child will grow continuously and gradually over time. The height of the child increases at various rates during different periods of life, but it generally moves smoothly from one height to another with no abrupt jumps.

Step 3: Visualize the quantized growth process

If we quantize human height in one-foot increments, a child's growth process would be quite different. Instead of growing continuously and gradually, the child would only be able to "jump" from one height to the next whole-foot increment. For example, imagine a child who starts at 3 feet tall. In the quantized growth scenario, the child would not be able to grow to 3 feet and 2 inches or even 3 feet and 11 inches. Instead, the child would only be able to grow to 4 feet tall, making an abrupt, instantaneous jump from 3 feet tall to 4 feet tall, with no intermediate heights possible. This process would continue, as the child would grow only in one-foot increments with each growth spurt.

Step 4: Discuss the implications of quantized growth

Quantizing human height in this way could have many implications. One such implication is that children would not be able to gradually "outgrow" their clothes, shoes, and other items - they would need an entirely new wardrobe each time they had a growth spurt. Additionally, quantized growth could potentially make tracking a child's growth more difficult, as the child might go through long periods with no apparent growth followed by a sudden, instantaneous increase in height. Moreover, this kind of growth pattern could also lead to social challenges, considering the adjustments children would have to make in their relationships and peer interactions after an abrupt change in height.
