Hamilton: An American Musical is a sung-and-rapped-through musical by Lin-Manuel Miranda. It tells the story of American Founding Father Alexander Hamilton. Miranda said he was inspired to write the musical after reading the 2004 biography Alexander Hamilton by Ron Chernow. The show draws heavily from hip hop, as well as R&B, pop, soul, and traditional-style show tunes. It casts non-white actors as the Founding Fathers and other historical figures. Miranda described Hamilton as about "America then, as told by America now".From its opening, Hamilton received critical acclaim. It premiered Off-Broadway on February 17, 2015, at the Public Theater, with Miranda playing the role of Alexander Hamilton, where its several-month engagement was sold out. The musical won eight Drama Desk Awards, including Outstanding Musical. It then transferred to the Richard Rodgers Theatre on Broadway, opening on August 6, 2015, where it received uniformly positive reviews and high box office sales. At the 70th Tony Awards, Hamilton received a record-breaking 16 nominations and won 11 awards, including Best Musical. It received the 2016 Pulitzer Prize for Drama. A filmed version of the Broadway production was released in 2020 on Disney+.
The Chicago production of Hamilton began preview performances at the CIBC Theatre in September 2016 and opened the following month. The West End production opened at the Victoria Palace Theatre in London on December 21, 2017, following previews from December 6 and winning seven Olivier Awards in 2018, including Best New Musical. The first U.S. national tour began in March 2017. A second U.S. tour opened in February 2018. Hamilton's third U.S. tour began January 11, 2019, with a three-week engagement in Puerto Rico in which Miranda returned to the role of Hamilton.
In Hamilton's "on a general method in dynamics", he starts with varying the function ##U## and writes the equation:
$$\delta U=\sum m(\ddot x\delta x+\ddot y\delta y+\ddot z\delta z)$$
Then he defines ##T## to be:
$$T=\frac{1}{2}\sum m (\dot x^2+\dot y^2+\dot z^2)$$
Then by ##dT=dU##, he...

When we derive the Euler Lagrange equations using Hamilton's Principle, we make a point of varying the velocity and the position at the same time, (despite the fact that, normally, they are related through a derivative).

Once you have the hamiltonian how can you find conserved quantities. I understand that if it has no explicit dependence on time then the hamiltonian itself is conserved, but how would you get specific conservation laws from this?

Hi, I was wondering about the interpretation of the Hamilton Jaccobi equation.
Naively we have H + \partialS/\partialt = 0 where H is the Hamiltonian and S is the action. But the action is the time integral of the Lagrangian so you would expect \partialS/\partialt = L
Thus H + L = KE +...
