Hamiltonian
Quick fact
The Hamiltonian was introduced by William Rowan Hamilton in 1833 and later became the foundation for Erwin Schrödinger's quantum wave equation, showing its deep link between energy and the evolution of systems.
Why this is interesting
Imagine a way to describe the total energy of a system that not only tells you how much energy it has, but also reveals the future motion of every particle. That's the power of the Hamiltonian.
