Question: A historian of science is studying the relationship between scientific discoveries and time intervals. Let \( h(x) \) be a polynomial representing a historical model of discoveries. Let \( x, y, z \) be positive real numbers such that \( x + y + z = 6 \). Find the minimum value of \( \frac{1}{x} + \frac{1}{y} + \frac{1}{z} \).
