AI Thread Summary
Diophantine linear equations have limited direct applications in physics, primarily due to their focus on integers and rational values, contrasting with physics' reliance on real numbers and smooth changes. An example discussed involves balancing weights on a hinged rod, illustrating a mathematical rather than a physical problem. The discussion highlights that while certain physical phenomena, like particle energy levels, can exhibit integer characteristics, they do not typically align with the nature of Diophantine equations. The problem of balancing weights is framed as more relevant to number theory than to practical physics. Overall, the intersection of Diophantine equations and physics remains largely theoretical and abstract.

diophantine equations
Hello, can anyone tell me about applications of Diophantine linear equations to physics?The only example that comes to mind is that of a series of weights. I have a measuring rod that is 40cm long and hinged in the middle. If I put a 40g weight at one end, how can I place 5g, 7g, 11g, 13g, 17g, 19g weights for balance?Thank you

Diophantine equations deal with integers or at best rational values. Such problems so to say have "singularity" at every point where they exist. non-existing derivatives etc. Physics on the other hand normally deals with really real values, smooth changes of every parameter etc.

The only field where physical things become integer (to my meek knowledge) is the world of particles - energy levels, spins, charges, etc. However I suspect this won't help much as any problem based on Diophantine equations is usually quite artificial with values specially picked for purpose.

The example with weights you give is honestly not physical, it's a problem for math, number theory or even we can call it "discrete analysis" - weights could be substituted with banknote values for example - and problem won't suffer.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
