De Donder–Weyl theory
De Donder-Weyl theory is a way to understand how particles move through space and time. It's like playing with marbles on a wooden board, but instead of marbles, we use particles, and instead of a wooden board, we use a mathematical space.
Imagine a toy car moving on a track. The car can move forward, backward, left, and right, but it can only move on the track. Now, imagine that the car is a particle, and the track is a mathematical space. This mathematical space has coordinates like latitude and longitude on a map, but we call them "phase space coordinates."
In the De Donder-Weyl theory, we use the idea of the "Hamiltonian." The Hamiltonian is like a rulebook that tells the particles how to move in the phase space. It's like a coach telling a basketball team how to move on the court.
So, Hamiltonian is a set of equations that tells a particle where to move based on different possible paths it can take. The particle can take different paths because it can have different amounts of energy or other properties that affect its movement.
The De Donder-Weyl theory is a way to understand these different paths and how particles move through space and time. Just like how a basketball team can have different strategies for different games, the De Donder-Weyl theory helps us come up with different strategies for particles in different situations.
Overall, the De Donder-Weyl theory is like a rulebook for particles' movements in the mathematical space. By using the Hamiltonian equations to figure out different possible paths, we can better understand how particles move through space and time.
