trust me, bro:
here is the receipt.
the claim

The principle of stationary action is also known as the variational principle or Hamilton’s principle.

6 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the principle of stationary action is also known as the variational principle or Hamilton’s principle?

Yes. Multiple physics reference and research sources confirm that the principle of stationary action is equivalently known as Hamilton's principle and relies on variational calculus.
