PeroK replied to the thread Difficulty understanding the reasoning behind constraint equations in mechanical systems.There's an Introductory Physics Homework section. It has a template. -
PeroK replied to the thread Difficulty understanding the reasoning behind constraint equations in mechanical systems.I guess you eventually need to express ##a_1## as a function of ##m_1, m_2, \alpha## and ##g##? -
PeroK replied to the thread Difficulty understanding the reasoning behind constraint equations in mechanical systems.You could post this under homework. I looked more closely and those diagrams and it's a little complicated. Three suggestions: 1) You... -
PeroK replied to the thread How to get peers to review your work?.I didn't think there were any elementary experiments that tested GR. As distinct from Newtonian gravity. Pound-Rebka or Hafele-Keating... -
PeroK replied to the thread Difficulty understanding the reasoning behind constraint equations in mechanical systems.:welcome: Physical constraints are usually based on a physical understanding of the problem. In general, we have to figure out how to... -
PeroK replied to the thread How to get peers to review your work?.It depends what the paper is about. If it's along the lines of: "There is a fundamental flaw in relativity and/or QM that physicists... -
PeroK replied to the thread How to get peers to review your work?.I think the OP already found that... -
PeroK reacted to nataliaeggers's post in the thread Why is it not allowed to question General Relativity? with
Skeptical.
Sure. Thanks for asking. I have empirical evidence that contradicts established scientific theories. It’s all experiments anyone can... -
PeroK replied to the thread Undergrad Are Boltzmann brains predicted by our current cosmological theories?.An entangled system of two particles, as it is usually presented, is a state associated with non-relativistic QM. How it is understood... -
PeroK reacted to .Scott's post in the thread Undergrad Are Boltzmann brains predicted by our current cosmological theories? with
Haha.
For an instant, I had this odd hallucination about a "PeroK". -
PeroK replied to the thread Undergrad Are Boltzmann brains predicted by our current cosmological theories?.I read that when you posted it and I'm still here, apparently. -
PeroK replied to the thread Undergrad Are Boltzmann brains predicted by our current cosmological theories?.I felt a bit like a Boltzmann brain yesterday, but not so much today! :welcome: -
PeroK replied to the thread High School How much lower would a sheep be expected to jump if on a steep upward slope?.It depends whether the sheep have perfected the Fosbury Flop. -
PeroK replied to the thread Mathematical definition of a rigid body.Reflection is impossible if each particle obeys Newton's laws of motion.
