PeroK's latest activity
-
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. -
PeroK replied to the thread Mathematical definition of a rigid body.I would have said that a rigid body is a set of particles whose pairwise distances from each other are constant. -
PeroK reacted to Nugatory's post in the thread High School True static equilibrium and effects on time with
Like.
You are just cheating yourself out of essential background understanding (which is the really fun part) if you've skipped chapters 1-3...
