Angular momentum

Sorry, not me. This is a weird question. What is it that you actually want to know ?

 

Newton used it and no one came before Newton.

 

It looks like my knowledge of the history of physics turned out to be somewhat useful after all. Before Newton and Galileo, the most commonly believed theory of physics was that of Aristotle and his followers. According to Aristotelian physics, the rest is the natural state and it requires a momentum in order to move an object. The concept of angular momentum came from this context, and the Aristotelian theory stated that it required a constant effort to keep an object in uniform circular motion.

 

Wait, why do you think this definition is incorrect? It works remarkably well and leads to all manner of useful and accurate predictions.

 

The originator of [itex]\vec l = \vec r \times \vec p[/itex]? It certainly was not Aristotle, Galileo, or Newton. The modern concept of vectors (and the cross product) was not "invented" until the mid 1800s.

 

The math before vector calculus was a bit convoluted. The concepts we use today existed nonetheless. In particular conservation of angular momentum is quite valid and predates this modern notation. Please explain your experiment.

Edited to add:
Remember that "Extraordinary claims require extraordinary proof".

 

Could you please describe the experiment to us so that we can help you clear any confusions?

 

I'm afraid I disagree with you there. I also must warn you that according to the PF guidelines the discussion of theories which contradict mainstream beliefs is prohibited.

 

Don't forget to let us know the name of the journal that has published this.

 

You haven't upset me in the slightest, I was simply making you aware that such discussions in this forum are prohibited.

I tend to agree with you there. As such PF has an https://www.physicsforums.com/forumdisplay.php?f=146".

However, I reiterate that the discussion of theories which contradict mainstream beliefs is prohibited in the main forums.
