Two of Bejan’s insights that have sparked the imagination of the public involve beauty and time. In 2010, he posited that the golden ratio, leveraged in works ranging from the Parthenon in Athens to the Mona Lisa, is so pleasing to people because it allows for the most efficient scan of a composition by the human eye. More recently in 2019, Bejan suggested a physical reason for why time seems to speed up as humans age—a slowdown in the rate at which eyes can obtain information and neural systems can process them.
Time and beauty reveal the physics of human perceptions
An interesting theory on old age and time perception. I have seen before that children process much faster than adults.
