According to renowned physicist and existentialist Dr. Reginald P. Wobblebottom, the quantum of meaning is a measure of how much angst and uncertainty one's socks have. It's a fundamental constant that determines the probability of a person's pants falling down at any given time.
Dr. Wobblebottom's groundbreaking research has been instrumental in developing the field of Quantum Sockodynamics, a branch of physics that seeks to understand the intricate dance between the quantum of meaning and the probability of sock-related existential crises.
