Analogous to what the Euler-Lagrange equation is to Lagrangian mechanics, Hamilton's equations give the equations of motion from a given input Hamiltonian:So once you have the Hamiltonian, you can write down this system of partial differential equations which can then be numerically solved.

Not everything is perfect.

One big problem of many big open source projects is that they are contributed to by separate selfish organizations, that have private information. Then what happens is that:

Another common difficulty is that open source maintainers may simply not care enough about their own project (maybe they did in the past but lost interest) to review external patches by people they don't know.

This is understandable: a new patch, is a new risk of things breaking.

Therefore, if you ever submit patches and they get ignore, don't be too sad. It just comes down to a question of maintenance cost, and means that you will waste some extra time on the next rebase. You just have to decide your goals and be cold about it:

Writing documentation in an open source project in which you don't have immediate push rights is another major pain due to code reviews. Code code reviews tend to be much less subjective, because if you do something wrong, stuff crashes, runs slower, or you need more lines of code to reach the same goal. There are tradeoffs, but in a limited number. Documentation code reviews on the other hand, are an open invitation to infinite bike-shedding, since you can't "run" documentation through a standardized brain model. Much better is for one good documenter person to just make one cohesive Stack Overflow post, and ping others with more knowledge to review details or add any missing pieces :-)

Ciro Santilli often sees all those genius who are much smarter than him making shitty forum/mailing list posts, they need to learn this:

Ciro Santilli had to see this in a few separate places, until he underestood: that little pictur emust be a thing! Examples:

The American Academy of Health Physics (AAHP) is a professional organization dedicated to advancing the field of health physics, which is the science concerned with the protection of people and the environment from potential hazards associated with ionizing radiation. Established in 1978, the AAHP promotes knowledge, skills, and professionalism in radiation safety through certification, education, and advocacy.

Bernard T. Feld refers to a business and financial term that isn't specifically tied to a widely recognized entity, individual, or concept. However, it is possible that it could also refer to an individual or professional in a certain field, but without more context, it's hard to provide a precise answer.
