comment Where can i get an online version of original works of Aristotlean physics (for free)?
@ChrisWhite His astronomy more "blatantly disagrees with reality" than his (philosophical) physics.

All Aristotle's works are available here from eBooks@Adelaide. Cf. also St. Thomas Aquinas's Commentaries on Aristotle (e.g., his In libros Physicorum), which includes verbatim Aristotle in both Greek and English and St. Thomas in both Latin and English.

comment Why is a random walk's RMS distance from the starting position$\propto\sqrt{N}$?
@DanielSank That proof would be independent of the number of dimensions?

revised Why is a random walk's RMS distance from the starting position$\propto\sqrt{N}$?
I am not asking a homework question, so I removed that tag. I also rephrased the question so as not to sound as though it's solliciting an answer to a homework problem.

@DanielSank I saw a proof that used integrals. I don't recall it being as easy as the proof that focuses on probability (e.g., $\langle\rangle$) rules.

comment Why doesn’t the Sagnac Effect disprove relativity?
@JohnDuffield What is the difference between "the measured speed of light" and "the speed of light"?

Special or General Relativity or both?

comment Why doesn’t the Sagnac Effect disprove relativity?
@JohnDuffield At the very beginning of his "On the Electrodynamics of Moving Bodies," the paper in which he gives SR's fundamental assumptions, he writes: "In agreement with experience we further assume the quantity [c] to be a universal constant—the velocity of light in empty space." (I §1). How does Sagnac agree with this assumption?

@JohnDuffield So Sagnac only disproves special relativity? Special relativity says the speed of light is constant in a vacuum.

@ssamuel "Data in modern computer systems aren't ever deleted in the sense described above" unless you use shred or something similar.

comment A mass falls to the ground from a height. What's the change of the entropy of the universe?
The thermodynamics of the universe as a whole is highly problematic. See, e.g., Kragh, Helge. “Pierre Duhem, Entropy, and Christian Faith.” Physics in Perspective 10, no. 4 (December 1, 2008): 379–95. doi:10.1007/s00016-007-0365-z.
