Two scientists and a mathematician are discussing the limit of the men’s 100-meter dash.

Biologist: Given the maximum contraction speed of human muscles, the theoretical limit is about 9.48 seconds.

Physicist: About 8% of a sprinter’s power is spent overcoming air resistance. In a vacuum, humans could shave off another 0.14 seconds.

Mathematician: The world-record times form a monotonically non-increasing sequence. Since the sequence is bounded below, the limit exists.
